If you owe back taxes in Rockville, here is the 2026 picture

Maryland stacks a county-level "piggyback" income tax on top of the graduated state personal income tax. The state rate runs from 2.0% to 5.75% under Md. Code, Tax-General § 10-105, and Montgomery County layers another 3.20% local income tax on top — the maximum local rate allowed in Maryland, tied with Baltimore City and Howard County. The combined top marginal rate for a Rockville resident hits 8.95%, putting Montgomery County among the highest state-plus-local income tax burdens in the country for middle-income earners. The corporate rate is 8.0% under Md. Code, Tax-General § 10-105(c). Maryland is also one of only two states (with New Jersey) that imposes both a Maryland estate tax and a separate Maryland inheritance tax on the same death.

If you have received an IRS CP504, LT11, or Statutory Notice of Deficiency, or if the Maryland Comptroller of Treasury has issued a Notice of Assessment with proposed tax, penalty, and interest, the deadline to act is short. We pull your IRS account transcripts, calculate your CSED, file Form 2848 Power of Attorney with the IRS and Form 548 with the Maryland Comptroller, and put administrative brakes on collection while the case is built.

Federal tax representation for Rockville taxpayers

Victory Tax Lawyers, LLP is a California-Bar-admitted tax-resolution law firm based in Los Angeles. Our federal practice runs nationwide: the Internal Revenue Service accepts our Form 2848 Power of Attorney in every state, and the U.S. Tax Court — a single federal tribunal with jurisdiction over IRS deficiency cases — holds regular trial sessions serving Maryland taxpayers at the Edward A. Garmatz United States Courthouse, 101 W Lombard Street in Baltimore (roughly 30 miles northeast of Rockville). From our Robertson Boulevard office in Los Angeles, we represent Rockville residents, Montgomery County biotech executives, NIH researchers, and Maryland-domiciled businesses in IRS audits, collection cases, Tax Court petitions, Offers in Compromise under IRC § 7122, Installment Agreements under IRC § 6159, lien discharges under IRC § 6325, levy releases under IRC § 6343, and Trust Fund Recovery Penalty defenses under IRC § 6672.

For Maryland state tax matters — the 2.0% to 5.75% graduated personal income tax under Md. Code, Tax-General § 10-105, the 3.20% Montgomery County piggyback local rate, the 8.0% Maryland corporate income tax, the 6.0% state sales tax under Md. Code, Tax-General § 11-101 (with a higher 9.0% rate on alcohol), withholding-tax assessments, or contested matters headed to the Maryland Tax Court — we file Form 548 with the Comptroller and handle the administrative track directly. For formal litigation in the Maryland Tax Court (the state's specialized administrative tribunal, established in 1959 and one of the oldest dedicated state tax tribunals in the country, seated at 6 Saint Paul Street in Baltimore) or in the Maryland Court of Special Appeals, we refer to locally admitted Maryland counsel under a co-counsel arrangement. The federal layer is where most Rockville high-income, biotech-executive, and NIH-researcher cases live, and that is where our engagement carries the load.

Rockville sits at the center of one of the densest federal-and-biotech economies in the country. The National Institutes of Health main campus in Bethesda, five miles south, anchors a workforce of more than 20,000 federal employees, intramural researchers, postdoctoral fellows on F32 and NRSA appointments, and 1099 grant-supported principal investigators. Walter Reed National Military Medical Center and the former Naval Medical Center Bethesda add a layer of military-physician W-2 and combat-zone-exclusion considerations under IRC § 112. The I-270 biotech corridor running through Rockville, Gaithersburg, and Germantown houses GSK, AstraZeneca (with MedImmune as its biologics arm in nearby Gaithersburg), Genentech, Lonza, Catalent, United Therapeutics, Emergent BioSolutions, Novavax, and Macrogenics — each producing the RSU, ISO, IRC § 83(b), and IRC § 1202 qualified-small-business-stock fact patterns that drive the heaviest federal cases on the corridor. Montgomery County's combined 8.95% state-plus-local rate compounds every federal adjustment. The federal procedures are uniform; the facts are Rockville-specific.

Your tax rights as a Rockville taxpayer

Two parallel rights frameworks apply when you owe tax. Federal rights come from the Internal Revenue Code and IRS Publication 1, the Taxpayer Bill of Rights. State rights come from the Tax-General Article of the Maryland Code and the Comptroller's Taxpayer Bill of Rights. Knowing both is the difference between a clean resolution and a missed 30-day Maryland Tax Court appeal window that ends in a state tax lien against your King Farm, Twinbrook, or Fallsmead property.

Right to representation

IRC § 7521(b)(2) and (c) give you the right to be represented by an attorney, CPA, or Enrolled Agent during any IRS examination or interview. Once Form 2848 is on file, the IRS must deal with us first, not you. Maryland mirrors this through Comptroller Form 548 Power of Attorney, accepted for all Comptroller of Treasury matters including Montgomery County local-income-tax issues administered by the Comptroller.

Right to U.S. Tax Court review

IRC § 6213(a) gives you 90 days from a Statutory Notice of Deficiency to petition the U.S. Tax Court without paying the tax first. Miss the 90 days and the federal assessment becomes final. The U.S. Tax Court holds regular trial sessions serving Maryland taxpayers in Baltimore at the Edward A. Garmatz United States Courthouse, 101 W Lombard Street — about 30 miles northeast of Rockville.

Right to Maryland Tax Court review

Md. Code, Tax-General § 13-510 gives you 30 days from a final Comptroller Notice of Assessment to appeal to the Maryland Tax Court — the state's specialized administrative tribunal seated at 6 Saint Paul Street in Baltimore. The 30-day window is much tighter than the federal 90-day Tax Court deadline. Missing it forfeits the right to pre-payment review.

Collection Due Process

IRC § 6320 (lien) and IRC § 6330 (levy) give you a 30-day window to request a CDP hearing once the IRS files a Notice of Federal Tax Lien or issues a Final Notice of Intent to Levy. A timely CDP filing halts collection and preserves judicial review through the Tax Court.

Right to settle for less than owed

Federally, IRC § 7122 authorizes Offers in Compromise based on doubt as to liability, doubt as to collectibility, or effective tax administration. Maryland runs a parallel program under Md. Code, Tax-General § 13-1101 and Comptroller Form MD 656, with similar hardship and insolvency standards. Both programs require all returns filed before consideration.

Right to recover fees

IRC § 7430 allows recovery of administrative and litigation costs if the IRS takes a position that is not substantially justified and the taxpayer prevails. The threshold is high, but real, especially in audit reconsideration and Innocent Spouse cases under IRC § 6015.

How Victory Tax Lawyers helps Rockville taxpayers

Offer in Compromise under IRC § 7122

We file Form 656 with Form 433-A(OIC) or 433-B(OIC), document the Reasonable Collection Potential, and negotiate doubt-as-to-collectibility offers when full collection is not feasible within the remaining CSED. For Rockville taxpayers, a federal OIC does not resolve Maryland state liability; we run a parallel Maryland Form MD 656 filing with the Comptroller of Treasury under Md. Code, Tax-General § 13-1101 where the state debt is real. The combined 8.95% Montgomery County rate often produces a state component that materially affects RCP.

Installment Agreements under IRC § 6159

Streamlined IAs (under $50,000), partial-pay IAs under IRC § 6159(d), and full-pay agreements. We push for partial-pay structures where the IRC § 6502 ten-year CSED will extinguish the balance before payoff — an underused resolution path for Rockville taxpayers carrying between $50,000 and $250,000 in federal debt, particularly NIH grant recipients and biotech employees whose RSU vests have caught up with them.

Lien discharge, subordination, and withdrawal

When a Notice of Federal Tax Lien blocks a Rockville property sale or refinance, we file Form 14135 (discharge), Form 14134 (subordination), or Form 12277 (withdrawal). NFTLs filed with the Circuit Court for Montgomery County Clerk in Rockville encumber title on King Farm, Twinbrook, Fallsmead, Aspen Hill, Potomac, and North Bethesda properties; the IRS procedures under IRC § 6325 set the cure path. Timing must align with the closing.

Levy release under IRC § 6343

Wage levies, bank levies, and accounts-receivable levies. We document economic hardship under IRC § 6343(a)(1)(D) and Treasury Reg. § 301.6343-1(b)(4), and where the levy is procedurally defective, we challenge it through Collection Due Process or Appeals. Maryland state tax liens follow a parallel track under Md. Code, Tax-General § 13-805 and § 13-806, recorded with the Circuit Court Clerk in the county of the taxpayer's property.

Audit defense and U.S. Tax Court litigation

Correspondence audits, office audits, and field examinations — including sensitive issues like cryptocurrency, foreign accounts under FinCEN Form 114 (FBAR), S-corporation reasonable-compensation, NIH postdoctoral fellowship characterization under IRC § 117(c) and Publication 970, IRC § 174 capitalization of biotech research expenditures, and IRC § 1202 qualified-small-business-stock exclusion claims on biotech founder shares. If the audit closes unfavorably, we petition the U.S. Tax Court within the 90-day IRC § 6213(a) window. Baltimore trial sessions cover Maryland taxpayers including those in Rockville.

Penalty abatement under IRC § 6651 and IRM 20.1.1

First-Time Abate administrative relief, reasonable-cause abatement, and statutory exceptions for failure-to-file and failure-to-pay penalties. On accuracy-related penalties under IRC § 6662, we document substantial authority or adequate disclosure to defeat the assessment. Maryland penalties under Md. Code, Tax-General § 13-701 and § 13-702 follow a separate reasonable-cause analysis applied by the Comptroller and reviewable by the Maryland Tax Court.

Twelve types of Rockville tax matters we handle

Federal cases for Rockville residents and businesses, framed against the Maryland Comptroller and Montgomery County overlay where it matters.

NIH postdoctoral fellowships and F32 awards

NIH F32 fellowships, NRSA-supported postdoctoral appointments, and intramural fellowships at the Bethesda main campus are routinely under-withheld. IRC § 117(a) excludes qualified-scholarship amounts for degree candidates only; IRC § 117(c) taxes the rest as ordinary income, with no withholding by the institution. Publication 970 sets out the analysis. Rockville fellows often face a five-figure April surprise once Montgomery County's 3.20% piggyback and Maryland's 5.75% state top rate stack on top.

Biotech RSU, ISO, and IRC § 83(b) elections

AstraZeneca, MedImmune, GSK, Lonza, Catalent, United Therapeutics, Emergent BioSolutions, Novavax, Macrogenics, and Genentech all issue equity compensation along the I-270 corridor. RSU vest events generate W-2 inclusion taxed at the default 22% supplemental rate — well below the actual marginal rate for high earners. ISO disqualifying dispositions trigger AMT under IRC § 55. IRC § 83(b) elections for restricted-stock grants in early-stage biotechs demand exact 30-day filing windows.

IRC § 1202 qualified-small-business-stock exclusion

Early-stage I-270 biotech founders and employees frequently hold C-corporation stock that qualifies for the IRC § 1202 100% federal exclusion on up to $10 million of gain (or 10x basis), if the five-year holding period and active-business tests are met. The IRS scrutinizes § 1202 claims closely on audit. We document original issuance, gross-asset limits, and the redemption rules under § 1202(c)(3). Maryland does not conform fully to § 1202 — the gain may still be taxed at the 5.75% state plus 3.20% Montgomery County local layer.

IRC § 174 research-and-experimental capitalization

The Tax Cuts and Jobs Act amendment to IRC § 174, effective for tax years beginning after December 31, 2021, requires biotech and pharmaceutical companies to capitalize and amortize domestic R&E expenditures over five years (15 years for foreign research) rather than expensing them. Rockville and Gaithersburg pre-revenue biotechs took the largest hit; NIH-grant-supported research adds complication where grant funds are involved. We coordinate with the company's tax department on examination responses and Form 3115 method-change filings.

Trust Fund Recovery Penalty

IRC § 6672 imposes personal liability on officers, partners, and check-signers for unpaid employment-tax withholding. Rockville medical-practice owners (Shady Grove Adventist staff physicians with side practices, Holy Cross and MedStar Montgomery affiliates), restaurant owners around Rockville Town Center, and biotech startup founders are common targets. The IRS uses Form 4180 interviews to identify responsible persons; Maryland applies a parallel responsible-person rule to withheld state income tax under Md. Code, Tax-General § 13-1101.

Maryland estate and inheritance tax

Maryland is one of only two states (with New Jersey) that imposes both a state estate tax and a separate state inheritance tax on the same death. The Maryland estate tax exemption is $5 million per estate under Md. Code, Tax-General § 7-309; the inheritance tax under Md. Code, Tax-General § 7-204 hits non-lineal beneficiaries at 10%. Coordinating the federal estate tax (Form 706, $13.61M exemption for 2024) with both Maryland layers is its own engagement on top of a federal income-tax matter, particularly for Potomac and North Bethesda estates.

Notice of Federal Tax Lien

NFTLs filed with the Circuit Court for Montgomery County Clerk at the Rockville courthouse encumber title and trigger CDP rights under IRC § 6320. A parallel Maryland state tax lien may be recorded under Md. Code, Tax-General § 13-805. King Farm, Twinbrook, Fallsmead, Aspen Hill, Wheaton, and Bethesda refinances and sales stall fast when an NFTL hits the title search.

IRS bank or wage levy

Bank levies on accounts at Capital One (a major Maryland retail bank presence), Truist, PNC, Sandy Spring Bank (a Maryland-chartered community bank with Rockville branches), M&T, Wells Fargo, or Bank of America. Wage levies hit Rockville-area biotech employers, NIH contractors, and federal civilian payrolls within days of CP90 or LT11 issuance.

Passport revocation under IRC § 7345

A seriously delinquent tax debt (over $62,000 for 2025, indexed annually) triggers State Department certification and passport hold. With Dulles and Reagan National within reach and an unusually high frequency of international business travel by NIH researchers, NIH visiting fellows, biotech executives, and Indian-American and Korean-American Montgomery County residents, this hits Rockville taxpayers especially hard. We file the IRC § 7345(e) action to reverse the certification.

FBAR, FATCA, and Streamlined Filing

FinCEN Form 114 for foreign accounts over $10,000 aggregate. Montgomery County has one of the largest Asian-American populations by percentage of any U.S. suburb — substantial Indian-American, Korean-American, Chinese-American, and Iranian-American communities, plus a large Jewish-American and Israeli expatriate community in Rockville and surrounding Kemp Mill. FBAR exposure on Bank Hapoalim, Bank Leumi, Bank Discount Israel, State Bank of India, ICICI Bank, Korean Exchange Bank, and Bank of China accounts is steady. We run the IRS Streamlined Filing Compliance Procedures, IRC § 6038D Form 8938 cleanups, and ITIN applications routinely. Indian-treaty Article 4 residency tiebreakers and IRC § 911 Foreign Earned Income Exclusion for H-1B and L-1 visa holders round out the file.

NIH grant principal-investigator Schedule C

NIH grants paid to a principal investigator outside an institutional appointment are taxable as ordinary self-employment income on Schedule C, subject to IRC § 1401 self-employment tax. Rockville-area independent researchers, small biotech consultants, and grant-supported clinicians often miss the estimated-tax payments under IRC § 6654. IRC § 174 capitalization rules apply on the expense side; lab equipment may be eligible for IRC § 179 expensing within limits.

Federal employee and military physician tax issues

NIH civilian employees, Walter Reed National Military Medical Center uniformed-service physicians, NIST in Gaithersburg, the Department of Energy, the FDA campus in White Oak, and the cluster of federal contractors in the Rockville-Bethesda-Gaithersburg corridor produce a steady book of federal-employee W-2 cases, security-clearance debt sensitivity, IRC § 112 combat-zone exclusion for deployed military, and 1099 contractor underpayment under IRC § 6654.

Nine common causes of tax debt for Rockville taxpayers

Patterns we see repeatedly in Rockville-based engagements. None of them are unusual — all of them are resolvable.

1. Underwithheld RSU vest events

An AstraZeneca, MedImmune, United Therapeutics, or Emergent BioSolutions employee at the 35% or 37% federal marginal bracket sees only 22% supplemental withholding on RSU vests. The shortfall, plus 5.75% Maryland plus 3.20% Montgomery County, produces a five-figure balance due the following April.

2. NIH fellowship under-withholding

F32 and NRSA postdoctoral fellowships at the NIH Bethesda campus are not subject to mandatory federal withholding. Fellows who relocated from Massachusetts, North Carolina, or California to take an NIH appointment often discover the gap only when the first April federal balance and the Maryland-plus-Montgomery layer arrive together.

3. Self-employment underpayment

Shady Grove and Holy Cross attending physicians with private 1099 practices, consultants serving the federal-contracting corridor, real-estate agents working King Farm and Potomac, and tradespeople file Schedule C or K-1 income with no estimated-tax payments. The first IRS CP14 lands the following spring with penalties under IRC § 6654.

4. Business closure

When a biotech LLC or S-corp closes with unpaid Form 941 payroll-tax balances, IRC § 6672 follows the responsible officer personally — well after the entity is dissolved. Common in pre-revenue biotech startups that ran out of Series A runway.

5. Divorce and joint-return fallout

A jointly-filed return tied to a now-former spouse's understatement leaves both parties liable until Innocent Spouse relief under IRC § 6015 is granted. Common when one spouse holds biotech equity and the other did not see the K-1 detail.

6. Cryptocurrency CP2000 surprise

Exchanges issue Form 1099-DA (introduced 2025), and the IRS computer matches reported gains. Missed basis records turn into ordinary-income assessments at the full sale price. Rockville's biotech and federal-tech populations carry steady crypto exposure from 2021-2024.

7. Late-filed or unfiled returns

Failure-to-file under IRC § 6651(a)(1) compounds at 5% per month, capped at 25%. After three years, refunds are barred under IRC § 6511. Maryland mirrors the federal three-year refund bar under Md. Code, Tax-General § 13-1104.

8. Real-estate sale without estimated tax

A North Bethesda, Potomac, King Farm, or Twinbrook home sale generating substantial capital gain, with no Form 1040-ES payment, produces a tax bill the next April. Investor flips taxed at ordinary-income rates — not capital-gain — under the dealer-status rules of IRC § 1221.

9. Stock-option exercise without planning

ISO disqualifying dispositions and NSO ordinary-income inclusions hit Rockville biotech, federal-tech, and pharmaceutical employees with AMT under IRC § 55 and large balances due. IRC § 83(b) elections missed within the 30-day window create their own irreversible problem.

Eight tax liabilities that pull in Rockville taxpayers

Federal authority alongside the Maryland statute where there is a parallel.

Failure to file federal return

IRC § 6651(a)(1) imposes 5%/month, max 25%, plus interest under IRC § 6601. The Maryland mirror is Md. Code, Tax-General § 13-701 imposing a similar late-filing penalty on unpaid Maryland tax.

Failure to file Maryland state return

Md. Code, Tax-General § 13-701 imposes a 10% penalty on the unpaid tax for failure to file, plus interest under § 13-604. The Comptroller may issue a Notice of Assessment under § 13-401 triggering the 30-day Maryland Tax Court appeal window. The Montgomery County local piggyback rate of 3.20% is collected by the Comptroller and distributed to the county.

Federal § 7122 Offer in Compromise eligibility

All federal returns must be filed (IRC § 7122(d) compliance) and the offer must reflect Reasonable Collection Potential. The non-refundable $205 application fee may be waived for low-income certified offers.

Maryland sales-tax delinquency

Md. Code, Tax-General § 11-101 sets the 6.0% state sales tax (Maryland has no local-option sales tax stack, simplifying the rate but raising the base). The 9.0% rate on alcohol is administered separately. Md. Code § 13-1101 imposes personal liability on responsible persons for unpaid trust-fund sales tax.

Trust Fund Recovery Penalty

IRC § 6672 imposes 100% personal liability on responsible persons for unpaid trust-fund employment tax. Maryland applies a parallel responsible-person rule to withheld state income tax under Md. Code, Tax-General § 13-1101.

Accuracy-related penalty

IRC § 6662 imposes 20% on substantial-understatement or negligence; IRC § 6663 imposes 75% on fraud. Defense is built on substantial authority, adequate disclosure, or reasonable cause — particularly relevant on biotech IRC § 1202 QSBS positions and IRC § 174 R&E capitalization disputes.

Maryland estate and inheritance tax

Md. Code, Tax-General § 7-309 imposes the Maryland estate tax (16% top rate on amounts over $5 million). Md. Code, Tax-General § 7-204 imposes a separate Maryland inheritance tax at 10% on transfers to non-lineal beneficiaries (siblings, nieces/nephews, friends; lineal descendants and spouses are exempt). The two layers can apply to the same decedent's estate, with separate filings on Form MET-1 and Form MET-2.

Transferee liability

IRC § 6901 lets the IRS pursue a transferee — a person who received property from a delinquent taxpayer — for the transferor's unpaid tax, up to the value of the transferred property.

What resolution can look like

Debt reduced

An accepted IRC § 7122 Offer in Compromise can resolve six-figure balances for cents on the dollar where Reasonable Collection Potential supports the offer. The acceptance rate sits around 33% nationally; preparation determines the outcome.

Penalties abated

First-Time Abate removes a single year of failure-to-file or failure-to-pay penalties for taxpayers with a clean three-year compliance record. Reasonable-cause abatement under IRM 20.1.1 reaches further when supported by documentation.

Lien released or withdrawn

Once a debt is paid in full, the IRS releases the Notice of Federal Tax Lien within 30 days per IRC § 6325(a). On an Installment Agreement of $25,000 or less, lien withdrawal under Form 12277 can be requested to clear title with the Circuit Court for Montgomery County Clerk.

Sample tax-resolution outcomes

Anonymized client matters drawn from our $100M+ aggregate tax-relief record across 2,000+ resolved cases.

Year	Tax debt	Resolution	Final outcome
2024	$152,296	IRC § 6159 Installment Agreement	Accepted at $25/month, partial-pay
2024	$138,296	Streamlined Installment Agreement	Accepted at $25/month
2023	$130,555	Partial-Pay Installment Agreement	Accepted at $50/month
2023	$128,206	IRC § 6159 Installment Agreement	Accepted at $25/month
2022	$116,451	Partial-Pay Installment Agreement	Accepted at $50/month

Past results do not guarantee future outcomes. Each tax case is unique. Results depend on the specific facts of the matter, including the taxpayer's financial condition, compliance history, and the discretion of the Internal Revenue Service and the Maryland Comptroller of Treasury.

Why Victory Tax Lawyers for a Rockville federal-tax case

Victory Tax Lawyers is California-Bar-admitted, not Maryland-Bar-admitted. That distinction matters — and it does not block our work. The U.S. Tax Court is a federal court with nationwide jurisdiction; an attorney admitted to that court may petition and try cases at any of its trial locations, including Baltimore at the Edward A. Garmatz United States Courthouse for Maryland taxpayers. IRS administrative practice runs on Form 2848 Power of Attorney, which is accepted from any attorney in good standing with any state bar plus an active Centralized Authorization File number. Most of our Rockville clients never need a separately admitted Maryland attorney because the case is, at its core, federal.

For administrative work before the Maryland Comptroller of Treasury — protests, audit responses, OIC submissions under Md. Code, Tax-General § 13-1101, and installment-agreement requests — we file Comptroller Form 548 Power of Attorney and handle the matter remotely. When a case must move to the Maryland Tax Court (the state's specialized administrative tribunal, established 1959, seated at 6 Saint Paul Street in Baltimore) or appeal further to the Maryland Court of Special Appeals, we coordinate with locally admitted Maryland counsel under a co-counsel arrangement. The federal portion of the engagement, which is usually the bigger exposure given Maryland's high combined state-plus-local income-tax burden, stays with us.

What distinguishes our firm: a California-Bar-admitted managing attorney with active U.S. Tax Court admission, an Enrolled Agent on staff for IRS administrative work, a 5.0 / 72-review Google rating, and $100M+ in cumulative tax relief secured across 2,000+ resolved matters. No marketing claim of being a Maryland-licensed firm — we are not. A factually accurate offer of federal tax representation, available to any Rockville taxpayer, at the same standard we apply to a Los Angeles client. Our 100% remote workflow runs through a secure document portal — you never have to drive to Robertson Boulevard.

Our seven-step process for Rockville clients

Free consultation

A 30-minute call with a tax attorney to scope your matter, identify deadlines, and decide whether engagement is the right move.

Engagement letter

A written scope, fee structure, and conflict check. Flat fees for administrative resolution; hourly or hybrid for litigation.

Form 2848 and CAF

We file the federal Power of Attorney with the IRS and Form 548 with the Maryland Comptroller, register on the CAF system, and step in as the contact of record.

Transcript and CSED analysis

We pull IRS account transcripts via Form 8821, calculate each year's CSED under IRC § 6502, and identify tolling events.

Strategy memo

A written summary: the resolution path (OIC, IA, CNC, audit response, CDP, Tax Court), the timeline, and the realistic outcome range.

Filing and negotiation

We file the operative document — Form 656, Form 433-A(OIC), Form 9423, Form 12153, or a Maryland Tax Court petition through local counsel — and handle every IRS and Comptroller contact.

Compliance monitoring

After resolution we monitor compliance through the OIC five-year terms or the IA term, file future returns, and prevent default.

Two collection clocks: federal CSED and Maryland's seven-year statute

The IRS has ten years from the date of assessment to collect a federal tax under IRC § 6502. After the Collection Statute Expiration Date, the debt is extinguished by operation of law. The clock pauses ("tolls") when an Offer in Compromise is pending, when a Collection Due Process petition is filed, during bankruptcy, when an installment agreement is requested, and when the taxpayer is outside the United States for six months or more — a common tolling event for NIH international researchers and biotech executives on extended overseas assignments.

Maryland runs a parallel state collection rule under Md. Code, Tax-General § 13-1103: the Comptroller must assess Maryland income tax within three years of the return due date (Md. Code, Tax-General § 13-1101 extends the period to seven years for substantial understatement or unreported gross income exceeding 25%, with no statute on collection in cases of fraud or non-filing). Once assessed, the Comptroller's collection right runs for seven years from the date of assessment under Md. Code, Tax-General § 13-1103, with renewal possible by re-recording the state tax lien. Many Rockville taxpayers carry a federal CSED that will run out before the Maryland collection statute expires — or vice versa. Pull both records and know both dates before agreeing to any payment plan or amended return that could restart a clock.

Rockville tax authorities and venues

A working knowledge of the tribunals, agencies, and field offices that touch a Rockville matter is what separates an answered Notice from a wage levy. Below is the working list our firm uses on every Rockville engagement.

Internal Revenue Service — Rockville/Wheaton TAC

The federal tax authority, at irs.gov. The IRS Taxpayer Assistance Center serving Rockville is located on the federal complex at 12055 Government Center Pkwy (with the Wheaton TAC frequently the closer practical option for Rockville residents). Appointments are required — verify the operating address on irs.gov before traveling. Most administrative work runs through the centralized IRS service centers, not the TAC.

U.S. Tax Court — Baltimore trial sessions

The U.S. Tax Court holds regular trial sessions for Maryland taxpayers in Baltimore at the Edward A. Garmatz United States Courthouse, 101 W Lombard Street, Baltimore MD 21201 — about 30 miles northeast of Rockville. Petitions are filed at ustaxcourt.gov; the 90-day deadline runs from the IRS Statutory Notice of Deficiency under IRC § 6213(a).

Maryland Comptroller of Treasury — Rockville office

The state tax authority, at marylandtaxes.gov. Headquartered at 80 Calvert Street, Annapolis MD 21401, with a Rockville taxpayer-service branch at 30 W Gude Drive, Suite 400, Rockville MD 20850. Administers the 2.0-5.75% graduated personal income tax, the 8.0% corporate income tax, the 6.0% state sales tax (9.0% on alcohol), withholding tax, the Montgomery County 3.20% piggyback local rate (collected by the Comptroller and distributed to the county), the Maryland estate tax under Md. Code, Tax-General § 7-309, the Maryland inheritance tax under § 7-204, and the Maryland Offer in Compromise program under Form MD 656.

Maryland Tax Court

The state's specialized administrative tax tribunal, established 1959 and among the oldest dedicated state tax tribunals in the country. Seated at 6 Saint Paul Street, 18th Floor, Baltimore MD 21202 — about 30 miles northeast of Rockville. Hears disputes between taxpayers and the Maryland Comptroller of Treasury, the State Department of Assessments and Taxation, and other tax-administering agencies. 30-day appeal deadline from a final Comptroller assessment under Md. Code, Tax-General § 13-510. Decisions are appealable to the Maryland Court of Special Appeals.

Montgomery County Department of Finance

The county finance authority for Montgomery County, located at 255 Rockville Pike, L-15, Rockville MD 20850. Administers Montgomery County property-tax billing and supports the Montgomery County 3.20% piggyback local income-tax rate (collected by the Maryland Comptroller and distributed back to the county). NFTLs affecting Montgomery County property — Rockville, Bethesda, Potomac, Gaithersburg, Germantown, Wheaton, Silver Spring, Chevy Chase — are recorded with the Circuit Court for Montgomery County Clerk in Rockville. The Montgomery County Department of Finance Tax Division at the same Rockville Pike address handles county property and special income-tax administration.

City of Rockville Department of Finance

The municipal finance authority for the City of Rockville (an incorporated municipality within Montgomery County), located at 111 Maryland Avenue, Room 100, Rockville MD 20850. Administers City of Rockville business licensing, the city's portion of property-tax billing, and municipal collections. Most state and federal income-tax obligations are administered by the Comptroller of Treasury and the IRS, not by the City of Rockville directly, but business-license and city-property issues touch the same engagement on certain matters.

Montgomery County Department of Permitting Services

Located in Rockville, the Department of Permitting Services handles county-level building permits, business licensing, and rental licensing — relevant on real-estate matters where a federal or Maryland audit reaches into short-term-rental compliance, dealer-status classification under IRC § 1221, or commercial-property cost-segregation studies.

U.S. District Court — District of Maryland, Greenbelt Division

Rockville sits within the Greenbelt Division of the U.S. District Court for the District of Maryland. Refund suits filed after payment of tax and exhaustion of administrative remedies under IRC § 7422 may be brought in the Greenbelt Division at 6500 Cherrywood Lane, Greenbelt MD 20770, or alternatively in the Baltimore Division at the Garmatz Courthouse or in the U.S. Court of Federal Claims in Washington, D.C.

IRS Independent Office of Appeals

The administrative-appeals body within the IRS that resolves cases without litigation. Rockville cases run through the Appeals offices serving the Mid-Atlantic region. Filings: Form 9423 (collection appeal) and Form 12153 (CDP). Page: irs.gov/appeals.

Taxpayer Advocate Service — Maryland

An independent organization within the IRS that helps when normal channels stall. The Local Taxpayer Advocate office serving Maryland handles Rockville cases. Page: taxpayeradvocate.irs.gov.

State Department of Assessments and Taxation (SDAT)

Maryland's separate property-tax assessment agency, headquartered at 700 E. Pratt Street, Baltimore MD 21202, with a Montgomery County local office that handles real-property assessments for Rockville and the surrounding county. Page: dat.maryland.gov. Administers real-property assessments, business personal-property reporting, and the Homestead Tax Credit. Property-tax assessment appeals run to the Property Tax Assessment Appeal Boards and then to the Maryland Tax Court.

Circuit Court for Montgomery County

Located in Rockville at the Montgomery County Judicial Center. The Clerk's office records Notices of Federal Tax Lien filed by the IRS and parallel Maryland state tax liens under Md. Code, Tax-General § 13-805 that encumber Montgomery County property. Title searches for Rockville real-estate transactions pull from this record.

Frequently asked questions — Rockville tax

Why is the Montgomery County combined income-tax rate so high?

Maryland is one of the few states that allows local jurisdictions to layer a "piggyback" income tax on top of the state graduated rate. The state personal income tax runs from 2.0% to 5.75% under Md. Code, Tax-General § 10-105. Montgomery County imposes the maximum-allowed local rate at 3.20% (tied with Baltimore City, Howard County, and Prince George's County). For a Rockville resident at the top state bracket, the combined state-plus-local rate hits 8.95% — one of the highest middle-and-upper-income marginal rates in the country, sitting closer to California's combined burden than to a neighboring jurisdiction like Northern Virginia (top rate 5.75% with no local layer). The Comptroller of Treasury collects the local piggyback alongside the state portion and distributes it back to Montgomery County.

Where is the closest U.S. Tax Court trial location to Rockville?

The U.S. Tax Court holds regular trial sessions in Baltimore at the Edward A. Garmatz United States Courthouse, 101 W Lombard Street — about 30 miles northeast of Rockville. A Rockville taxpayer can request the Baltimore trial location when filing the Tax Court petition; alternatively, Washington, D.C. trial sessions are held at the National Courts Building, 400 Second Street NW. Petitions are filed electronically through DAWSON at ustaxcourt.gov; the 90-day deadline from the IRS Statutory Notice of Deficiency under IRC § 6213(a) is jurisdictional — a single day late and the federal assessment becomes final.

What is the Maryland Tax Court and what is its deadline?

The Maryland Tax Court is the state's specialized administrative tax tribunal, established in 1959 and among the oldest dedicated state tax tribunals in the country. It sits at 6 Saint Paul Street, 18th Floor, Baltimore MD 21202, and hears disputes between taxpayers and the Maryland Comptroller of Treasury, the State Department of Assessments and Taxation, and other tax-administering agencies. The appeal deadline is 30 days from a final Comptroller assessment under Md. Code, Tax-General § 13-510 — significantly tighter than the federal 90-day Tax Court deadline. Decisions are appealable to the Maryland Court of Special Appeals. Victory Tax Lawyers refers Maryland Tax Court litigation to locally admitted Maryland counsel; we handle the federal portion and the Comptroller administrative work directly.

I'm an NIH postdoctoral fellow — is my F32 stipend taxable?

Usually yes, in full or in part. IRC § 117(a) excludes amounts paid as a "qualified scholarship" used for tuition and required fees of a degree candidate; IRC § 117(c) makes everything else taxable, including any portion of a fellowship paid for services and any portion paid for room, board, or general support. Most postdoctoral fellowships at the NIH (NIH F32 NRSA awards, intramural postdoctoral appointments, IRTA/CRTA fellowships) are not for degree candidates and are fully taxable. The institution often does not withhold federal income tax, so quarterly estimated payments under IRC § 6654 are required. Publication 970 sets out the analysis. Maryland follows the federal definition under Md. Code, Tax-General § 10-208 for additions and subtractions. The Montgomery County 3.20% local rate applies on top of the 5.75% Maryland rate, stacking quickly on a $60,000-$80,000 stipend.

I'm an NIH principal investigator with grant funds on Schedule C — how is that taxed?

NIH research grants paid to an independent principal investigator (rather than to an institution) are taxable as ordinary self-employment income reported on Schedule C and subject to IRC § 1401 self-employment tax. Grant funds spent on lab equipment, supplies, and reasonable salaries to employees are deductible under IRC § 162, but under the post-2021 IRC § 174 amendment, domestic research-and-experimental expenditures must be capitalized and amortized over five years rather than expensed in the year paid. Equipment may qualify for IRC § 179 expensing within annual limits. Estimated-tax payments under IRC § 6654 are required to avoid quarterly underpayment penalties. The Comptroller of Treasury treats NIH grants identically for Maryland purposes.

I work for AstraZeneca / MedImmune / United Therapeutics / Novavax and have RSUs — why did I owe so much tax this year?

RSU vest events are taxed as W-2 ordinary income at the supplemental wage withholding rate, which is currently 22% federal on amounts up to $1 million per year (37% above). If your actual marginal federal rate is 32%, 35%, or 37%, you are underwithheld by 10 to 15 percentage points on every vest. Add 5.75% Maryland state plus the 3.20% Montgomery County local piggyback (with limited state withholding on supplemental wages depending on the employer's setup) and a single year of vesting can produce a $30,000 to $100,000+ balance due. The fix is W-4 adjustment plus quarterly Form 1040-ES under IRC § 6654.

Can a California-Bar-admitted attorney represent me in Rockville?

For federal IRS matters — yes. The IRS accepts Form 2848 Power of Attorney from any attorney in good standing with any state bar. The U.S. Tax Court is a single federal court with nationwide jurisdiction; an attorney admitted to that court may represent a taxpayer at any Tax Court trial location, including Baltimore which covers Maryland. For Maryland Comptroller administrative work, we file Form 548 Power of Attorney and handle the matter remotely. For formal litigation in the Maryland Tax Court or a Maryland Court of Special Appeals proceeding, we co-counsel with locally admitted Maryland attorneys. Most engagements — audit defense, OIC, IA, levy release, Tax Court — are federal and stay entirely with our firm.

I hold founder stock in a Rockville biotech — can I claim the IRC § 1202 QSBS exclusion?

Possibly, and the analysis is fact-dependent. IRC § 1202 allows a 100% federal exclusion on up to $10 million of gain (or 10x basis, whichever is greater) on the sale of qualified small business stock held more than five years. The issuer must have been a domestic C corporation with gross assets of $50 million or less at the time of issuance, must have used 80% of its assets in an active business (most biotech R&D and clinical activity qualifies), and must not have engaged in disqualified redemptions under § 1202(c)(3). The five-year holding period is strict. Maryland does not fully conform to § 1202 — the gain may still be taxable at the 5.75% state rate plus the 3.20% Montgomery County local rate, although Maryland does provide some conformity through general capital-gain treatment. We document original issuance and run the § 1202 analysis case by case.

I have foreign bank accounts in India / Korea / China / Iran / Israel — what is my FBAR exposure?

If the aggregate value of your non-U.S. financial accounts exceeded $10,000 at any point during the calendar year, you are required to file FinCEN Form 114 (the FBAR). Montgomery County has one of the largest Asian-American and Middle Eastern-American populations by percentage of any U.S. suburb — substantial Indian-American (State Bank of India, ICICI Bank, HDFC Bank), Korean-American (Korean Exchange Bank, Woori Bank), Chinese-American (Bank of China, ICBC), Iranian-American (legacy Bank Saderat / Bank Melli relationships), and Jewish-American / Israeli expatriate (Bank Hapoalim, Bank Leumi, Bank Discount Israel) communities. FBAR penalties under 31 U.S.C. § 5321 can reach $10,000 per non-willful violation per year and 50% of the account balance per willful violation. The IRS Streamlined Filing Compliance Procedures (Domestic and Foreign) provide reduced-penalty correction paths. IRC § 6038D Form 8938 thresholds apply separately. We run these cleanups regularly.

I'm on an H-1B or L-1 visa working for a Rockville biotech — what tax issues do I face?

H-1B and L-1 visa holders working in Maryland are typically U.S. tax residents under the substantial-presence test of IRC § 7701(b) and are taxed on worldwide income. Common issues: missing reporting of foreign accounts (FBAR, Form 8938), failure to claim IRC § 911 Foreign Earned Income Exclusion in the year of arrival or departure, and dual-residency tiebreakers under the U.S.-India Article 4 or U.S.-Korea treaty residency articles. Departing visa holders may face a "sailing permit" issue under IRC § 6851. ITIN applications for spouses and dependents under W-7 are routine. We coordinate the federal positions with Maryland conformity rules where they diverge.

What is Maryland's collection statute of limitations?

Md. Code, Tax-General § 13-1101 gives the Comptroller three years from a return's due date to assess Maryland income tax (seven years for substantial understatement of gross income exceeding 25%, with no limit for fraud or unfiled returns). Once an assessment is final, the Comptroller's right to collect runs for seven years under Md. Code, Tax-General § 13-1103, renewable by re-recording the state tax lien. The federal CSED under IRC § 6502 is a separate ten-year clock running from the federal assessment date.

Can I be audited by both the IRS and the Maryland Comptroller for the same year?

Yes. The IRS and the Maryland Comptroller of Treasury operate independently and share information through the IRS-state exchange program. A federal audit adjustment is routinely reported to Maryland under the state's federal-change reporting rule (Md. Code, Tax-General § 13-409), and vice versa. We coordinate the two audits to prevent inconsistent positions on the federal record from costing you on the Maryland return — particularly important given the 3.20% Montgomery County piggyback, which multiplies any federal adjustment by an additional layer of state-plus-local tax.

Does Maryland offer an Offer in Compromise equivalent to the federal program?

Yes. The Maryland Comptroller of Treasury accepts Offers in Compromise on Form MD 656 under Md. Code, Tax-General § 13-1101 authority. The Comptroller considers offers based on doubt as to collectibility, doubt as to liability, and economic hardship — standards that parallel federal IRC § 7122 analysis but with state-specific procedural rules. All Maryland returns must be filed before consideration, and a financial-disclosure package is required. We typically run a state OIC in parallel with the federal Offer where both debts are real.

My family member died in Maryland — do I owe both estate and inheritance tax?

Potentially yes. Maryland is one of only two states (New Jersey is the other) that imposes both a state estate tax and a separate state inheritance tax on the same death. The Maryland estate tax under Md. Code, Tax-General § 7-309 applies to gross estates above $5 million per decedent, with a top rate of 16%, and is filed on Form MET-1. The Maryland inheritance tax under Md. Code, Tax-General § 7-204 is imposed on the beneficiary, not the estate, at a 10% rate on transfers to non-lineal beneficiaries (siblings, nieces, nephews, friends, business partners); transfers to spouses, parents, children, grandchildren, and other direct lineal descendants are exempt. The two layers can stack on the same estate. The federal estate tax under Form 706 ($13.61M exemption for 2024) is a third layer on top.

Can the IRS levy my Rockville bank account or wages?

Yes — after a Final Notice of Intent to Levy (CP90 or LT11) and expiration of the 30-day Collection Due Process window under IRC § 6330, the IRS may levy bank accounts at Capital One, Sandy Spring Bank, Truist, PNC, M&T, Wells Fargo, Bank of America, or any Maryland-chartered institution and serve wage levies on Rockville-area employers including AstraZeneca, MedImmune, GSK, United Therapeutics, Novavax, Emergent BioSolutions, and federal payrolls through the Defense Finance and Accounting Service for NIH and military physicians. A timely Form 12153 CDP request halts collection while the case is reviewed by Appeals. After a CDP determination, the taxpayer has 30 days to petition the U.S. Tax Court under IRC § 6330(d)(1). Maryland issues parallel state tax liens under Md. Code, Tax-General § 13-805 that work through Circuit Court Clerk filings.

What if I have unfiled returns going back several years?

The IRS Voluntary Filing Compliance policy and IRM 5.1.11.6 generally require the last six years of returns to bring a taxpayer back into compliance. Filing prior-year returns is the first step before any OIC, IA, or CNC request — IRC § 7122(d) compliance is a prerequisite for a federal Offer. Refunds claimed on returns filed more than three years after the original due date are time-barred under IRC § 6511(b)(2). Maryland follows a parallel filing-compliance posture; the Comptroller may assess based on the federal-change reporting rule or estimate tax under Md. Code, Tax-General § 13-401 when a taxpayer fails to file.

How long does a federal Offer in Compromise take to process?

An IRS Offer in Compromise typically takes six to twelve months from filing to a final decision. The IRS deems an Offer accepted if not rejected within 24 months under IRC § 7122(f). While the OIC is pending, IRC § 6331(k) bars most levies, and the CSED is tolled. Rejected offers carry a 30-day Appeals window. A well-documented Offer with a complete Form 433-A(OIC) or 433-B(OIC) financial package moves faster than one returned for incompleteness. A Maryland state OIC under Form MD 656 typically runs four to nine months on a parallel track.

Will hiring a tax attorney stop IRS collection action immediately?

Once Form 2848 is on file, the IRS routes all communication through the attorney and stops contacting the taxpayer directly. Active levies are not automatically lifted by the POA filing alone — release requires either a financial showing under IRC § 6343, a CDP filing under IRC § 6330, or an installment-agreement / OIC submission that triggers the IRC § 6331(k) collection bar. We move on those concurrently when a levy is in place. Maryland state collection follows a similar pattern: a Form 548 routes Comptroller contact, and a pending Maryland OIC pauses state tax-lien enforcement.
