Contra Costa County taxpayers facing IRS or FTB collection

If you live in Concord, Richmond, Antioch, Walnut Creek, San Ramon, Pittsburg, Brentwood, Pleasant Hill, Martinez, or any of the other incorporated cities in Contra Costa County, you sit inside one of the most distinctive corporate-headquarters concentrations in California. The Chevron Richmond refinery and Bishop Ranch business park in San Ramon — home to Chevron's corporate headquarters, Cooper Tire, GE Pharmaceuticals, and dozens of tech and pharma occupiers — drive executive compensation work involving Restricted Stock Units, Performance Stock Units, Incentive Stock Options under IRC §55, and Section 83(b) elections under IRC §83. SF and Oakland commuters in Walnut Creek and Lafayette generate Schedule C work-from-home and multi-state wage-allocation questions. Lamorinda — Lafayette, Moraga, and Orinda — concentrates high-net-worth estate, gift, and FTB residency matters. If you have an IRS or FTB balance, an audit notice, or a wage levy from the EDD, this page walks through what Contra Costa representation looks like.

Why Contra Costa County tax matters require a California-licensed firm

Contra Costa County is the ninth-most-populous county in California and arguably its densest corporate-headquarters footprint outside the City of San Francisco. The county is home to Chevron's global headquarters at Bishop Ranch in San Ramon, the Chevron Richmond refinery (one of the largest petroleum-refining complexes on the West Coast), AT&T's Western region operations also at Bishop Ranch, the Walnut Creek banking and finance corridor, and a Lamorinda enclave — Lafayette, Moraga, and Orinda — whose median household incomes and property values place it among the wealthiest sub-regions in Northern California. Layered on top: the Antioch and Pittsburg East-County suburbs that function as a commuter feeder for both the Bay Area and the Central Valley.

Victory Tax Lawyers, LLP is a California-licensed tax-law firm. Both managing attorneys — Parham Khorsandi, Cal Bar #266658, and Amir Boroumand, Cal Bar #269570 — are members of the State Bar of California in active standing and admitted to practice before the United States Tax Court. We represent Contra Costa County clients directly before the California Franchise Tax Board, CDTFA, EDD, and the California Office of Tax Appeals — no Power-of-Attorney workaround through out-of-state counsel, no referral chain.

On the federal side, our Tax Court bar admission has nationwide reach. A Contra Costa County petitioner designating the U.S. Tax Court's San Francisco trial city under Tax Court Rule 140 hears the case at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco. That same building houses the U.S. District Court for the Northern District of California, where federal refund suits and criminal-tax matters proceed.

The pages that follow lay out the practice areas, the venue map, settlement ranges from prior cases, the seven-step engagement process, and 12 FAQs answering what Contra Costa County taxpayers actually ask.

Your tax rights as a Contra Costa County taxpayer

Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1. California layers its own rights through the FTB Taxpayer Bill of Rights at Cal. Rev. & Tax. Code Part 10.7 and parallel provisions for CDTFA and EDD. Contra Costa County executives at Chevron, AT&T, Cooper Tire, and the Walnut Creek financial-services firms add a layer of stock-compensation issues that intersect with both regimes.

Right to representation (federal)

Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview when you state you wish to consult an authorized representative. Form 2848 puts a tax attorney between you and the IRS for the remainder of the matter.

Right to representation (California)

FTB Form 3520-PIT or 3520-BE appoints counsel before the Franchise Tax Board. CDTFA Form 392 covers sales-tax matters; EDD DE 48 covers payroll. Once on file, every notice routes to your attorney.

Right to Collection Due Process

A Notice of Federal Tax Lien (IRC §6320) or Final Notice of Intent to Levy (IRC §6330) opens a 30-day window to request a CDP hearing on Form 12153. A timely CDP request pauses federal collection and preserves Tax Court review.

Right to U.S. Tax Court review

A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Contra Costa County petitioners can designate San Francisco as the place of trial, with sessions at the Phillip Burton Federal Building.

Right to challenge MHST surtax allocation

Under Cal. Rev. & Tax. Code §17043, the Mental Health Services Act adds a 1 percent surtax on taxable income above $1 million. Chevron, AT&T, and Bishop Ranch executives with large RSU vest years routinely cross the threshold. Source-allocation arguments matter where part of the income relates to services performed outside California.

Right to a federal OIC

Under IRC §7122, the IRS may accept less than the full liability where doubt as to collectibility, doubt as to liability, or effective tax administration justifies settlement. Filed on Form 656 with Form 433-A(OIC) or 433-B(OIC).

Right to a California OIC

FTB compromise authority sits at Cal. Rev. & Tax. Code §19443. CDTFA runs a parallel offer program under §6832. EDD compromise sits at Cal. Unemp. Ins. Code §1735 and adjoining sections.

Right to a Collection Statute

IRC §6502 gives the IRS 10 years from assessment to collect. The California parallel under Cal. Rev. & Tax. Code §19255 runs 20 years — double the federal tail. Pull both transcripts before negotiating.

How Victory Tax Lawyers helps Contra Costa County taxpayers

Federal & California Offer in Compromise

We file federal Form 656 with Form 433-A(OIC) under IRC §7122, and FTB Form 4905 PIT or BE with the parallel financial under Cal. Rev. & Tax. Code §19443. The two reviews run on different Reasonable Collection Potential math, and California weighs Lamorinda real-estate equity (Lafayette, Moraga, Orinda) and Alamo, Danville, and Diablo properties tougher than the IRS does.

Installment Agreements (IRS & FTB)

Streamlined IRS IAs under $50,000, Non-Streamlined IAs above with Form 433-F disclosure, and Partial Pay IAs under IRC §6159 running through the CSED. FTB parallel plans under Form 3567; CDTFA and EDD have their own structures.

Lien release and withdrawal

A federal NFTL under IRC §6321 and FTB State Tax Liens under Cal. Gov. Code §7170 attach to Contra Costa County real property and are recorded with the Contra Costa County Clerk-Recorder in Martinez. We pursue release after payment, certificate of discharge, subordination for refinance, and lien withdrawal under Fresh Start for IAs under $25,000.

Levy release (IRS, FTB, EDD)

Federal wage and bank levies under IRC §6331 stop with CNC, an accepted IA, OIC processing, or a timely CDP. FTB Earnings Withholding Orders under Cal. Rev. & Tax. Code §18670 and bank levies under §18670.5 release under analogous resolutions. Federal bank levies hold 21 days; FTB holds 10 business days.

Audit and exam defense

IRS correspondence, office, and field audits with Walnut Creek-area examiners. FTB residency audits under Cal. Rev. & Tax. Code §17014 on Lamorinda and San Ramon executives relocating to Nevada, Texas, or Florida. CDTFA sales-tax audits on Walnut Creek restaurants, Concord retail, and Richmond marine-fuel dealers. EDD AB 5 audits on contractors classified as 1099 in construction, energy services, and tech.

Penalty abatement

Federal First-Time Penalty Abatement and reasonable-cause requests under IRC §6651. FTB waivers under Cal. Rev. & Tax. Code §19131 and §19132. Reasonable-cause for Contra Costa filers affected by 2017 and 2020 wildfire smoke, PG&E PSPS shutoffs, Chevron Richmond refinery flare events, and 2023 atmospheric-river flooding.

Twelve tax issues we handle for Contra Costa County clients

Federal and California state practice areas framed for the matters that walk through the door from San Ramon, Walnut Creek, Lafayette, Moraga, Orinda, Danville, Richmond, Concord, and the East County.

Chevron RSU and PSU underwithholding

Chevron Restricted Stock Unit and Performance Stock Unit vests at the San Ramon headquarters pile ordinary income onto W-2s. Employer withholding at the flat 22 percent supplemental rate underwithholds the all-in 37 percent federal plus California top brackets. April balances at six figures are routine. We file amended returns and structure payment plans.

Executive ISO and AMT exposure

Bishop Ranch tech and pharma executives at GE Pharmaceuticals, Cooper Tire, and resident startup occupiers who exercise Incentive Stock Options without selling create a preference item under IRC §55. A six-figure AMT bill on paper gains is common. We pursue Disqualifying Dispositions, AMT credit carryforwards, and reasonable-cause penalty defense.

Section 83(b) elections and missed windows

Bishop Ranch startup founders and pre-IPO grantees often miss the 30-day Section 83(b) window under IRC §83(b). Late filings are challenged, and the consequences compound at vest. We document mailing, USPS receipts, and reasonable cause where the window was missed.

Chevron refinery severance and retirement

Chevron Richmond refinery downsizing, voluntary separation packages, and early-retirement offers create lump-sum severance and pension events. Federal supplemental withholding rarely covers the all-in rate. We coordinate Form 5329 early-distribution penalty defense, Net Unrealized Appreciation under IRC §402(e), and rollover sequencing.

SF and Oakland commuter wage allocation

Walnut Creek and Lafayette residents who commute to San Francisco or Oakland for work, then converted to hybrid or remote in 2020-2024, face wage-allocation and home-office Schedule C questions. The City of San Francisco gross-receipts and payroll-expense taxes can also surface for employers and self-employed consultants.

FTB departing-resident audits

Lamorinda and San Ramon residents who moved to Nevada, Texas, or Florida often trip the nine-factor domicile test under Cal. Rev. & Tax. Code §17014. Properties retained in Lafayette, Orinda, Diablo, or Alamo weigh heavily. We document driver's-license changes, voter registration, and physical-presence days.

Mental Health Services Act 1% surtax

Chevron, AT&T, and Bishop Ranch executives, Walnut Creek wealth-management partners, and Lamorinda founders crossing $1 million in taxable income face the 1 percent MHSA surtax under Cal. Rev. & Tax. Code §17043. Income-sourcing arguments and timing of equity events become material.

Trust Fund Recovery Penalty

Under IRC §6672, the IRS reaches owners of Contra Costa County LLCs and S-corps for unpaid payroll trust funds after Form 4180 interviews. EDD asserts the parallel state piece under Cal. Unemp. Ins. Code §1735.

CDTFA sales-tax audits

Cash-intensive Walnut Creek downtown restaurants, Concord and Antioch retail, Richmond marine and fuel dealers, and Brentwood agricultural operators draw CDTFA mark-up audits. We push back on the test-period methodology before it scales across the audit period.

EDD AB 5 worker-classification

Post-AB 5 and Prop 22, EDD reclassifies 1099 contractors under the ABC test. Common in Contra Costa County energy-services contractors, construction, refinery turnaround crews, and tech consultants embedded at Bishop Ranch occupiers.

Estate and gift tax planning (Lamorinda)

Lafayette, Moraga, and Orinda concentrate high-net-worth households whose estates approach or exceed the federal exemption. We coordinate Form 706 estate returns, Form 709 gift returns, GST planning under IRC §2601, and Prop 19 parent-child property-tax exclusions with the County Assessor.

U.S. Tax Court petitions

A 90-day petition in response to a Notice of Deficiency, designating San Francisco as the place of trial. Sessions are held at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco.

Nine common causes of tax debt in Contra Costa County

1. RSU vest underwithholding

Chevron, AT&T, and Bishop Ranch employers withhold federal tax on RSU vests at the flat 22 percent supplemental rate. Employees in California's top brackets owe an additional 15 to 20 percent come April, and prior-year balances roll forward into wage levies if untreated.

2. ISO exercise without sale

A Bishop Ranch executive or San Ramon pre-IPO grantee exercises Incentive Stock Options, holds the shares, and triggers AMT on the spread between exercise price and fair-market value — even though no cash changed hands.

3. Refinery severance lump sums

A Chevron Richmond refinery operator or process engineer accepts a voluntary-separation package. The lump-sum severance, accrued vacation, and accelerated retirement distribution arrive in a single year, pushing the household into top brackets with under-withheld supplemental rates.

4. Small-business payroll lapses

A Walnut Creek restaurant or Concord contractor stops depositing Form 941 trust funds during a slow quarter. The IRS asserts TFRP under IRC §6672 against owners personally; EDD asserts the state side under Cal. Unemp. Ins. Code §1735.

5. Lamorinda real-estate sales

Lafayette, Moraga, Orinda, Alamo, Danville, and Diablo saw aggressive 2020-2023 appreciation. Investment-property sales without a like-kind exchange under IRC §1031 trigger federal capital gains plus California's ordinary-income treatment at 13.3 percent.

6. FTB residency audit after move

Retiring Chevron and AT&T executives relocating to Nevada, Texas, or Florida often retain a Lafayette or Orinda home, a Walnut Creek consulting practice, or California family ties — all factors the FTB weighs to assert continuing California domicile under §17014.

7. Multi-state wage allocation

Walnut Creek and Lafayette professionals who split time between an SF office, a remote Contra Costa home office, and travel to client sites in Nevada or Texas need source-rule allocation done correctly. Mistakes draw FTB Notices of Proposed Assessment two to three years later.

8. ERC clawback exposure

Employee Retention Credit claims filed by promoter mills for Contra Costa restaurants, dental practices, energy-services firms, and Bishop Ranch tenants are being clawed back through CP207 and CP207L letters.

9. Wildfire and PSPS gaps

Filers affected by 2017 Atlas Fire smoke, 2020 SCU Lightning Complex, recurring PG&E Public Safety Power Shutoffs, and 2023 atmospheric-river flooding missed deadlines. Disaster-zone extensions help during the active period, but penalty stacks accumulate once the window lapses.

Who is on the hook: eight Contra Costa County liability scenarios

Joint filers (community-property state)

California is a community-property state under Cal. Fam. Code §760. Joint federal returns create joint-and-several liability under IRC §6013(d)(3). One spouse can be pursued for the entire balance — even post-divorce — subject to Innocent Spouse Relief under IRC §6015 and Cal. Rev. & Tax. Code §18533.

Lamorinda HNW divorces and tax allocation

The Wakefield Taylor Courthouse at 725 Court Street in Martinez sees high-net-worth Lamorinda and San Ramon dissolutions. Allocation of joint federal liability, Chevron and AT&T deferred-compensation division under QDROs, and RSU vesting through transition matter. We coordinate with family-law counsel.

Responsible persons for payroll

TFRP under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes. The California parallel sits at Cal. Unemp. Ins. Code §1735 for EDD payroll personal liability.

CDTFA dual-determinations

CDTFA can issue personal dual-determinations against corporate officers, directors, and LLC members for unremitted sales tax under Cal. Rev. & Tax. Code §6829.

FTB suspended-entity exposure

A Contra Costa County LLC suspended by FTB under Cal. Rev. & Tax. Code §23301 loses its right to contract or defend in California courts. Officers signing on behalf may incur personal exposure.

Transferee liability

IRC §6901 reaches transferees where the transfer rendered the transferor insolvent and tax debt remains. Common with Prop 19 parent-child transfers of Lamorinda and Alamo real property and family-LLC restructurings.

Successor business liability

Asset purchases continuing a seller's Contra Costa County operation can carry CDTFA successor liability under Cal. Rev. & Tax. Code §6811-6814 and EDD successor liability under Cal. Unemp. Ins. Code §1731. Buyers protect with clearance letters.

Estate and decedent returns

California has no state estate tax. The decedent's final 1040 and the estate's 1041 are the executor's responsibility, with personal liability under 31 USC §3713(b) for premature distributions. Contra Costa County Superior Court probate jurisdiction at the Wakefield Taylor Courthouse governs the priority of state-tax claims.

What resolution can look like in Contra Costa County

Debt reduced

An accepted federal OIC settles the IRS liability for less than the full amount. A parallel FTB §19443 compromise can settle the California side. Partial Pay IAs cap recovery at what you can pay through the federal CSED or the FTB 20-year statute. Currently Not Collectible status freezes federal collection while finances stabilize after RSU vest spikes, refinery severance years, or business cycles.

Penalties abated

Federal First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests address PSPS shutoffs, fire-disaster periods, serious illness, and preparer reliance. FTB waivers under §19131 and §19132 follow parallel principles.

Liens and levies released

A federal NFTL recorded with the Contra Costa County Clerk-Recorder withdraws once a streamlined IA is in place under Fresh Start. FTB State Tax Liens release on payment, compromise, or release-for-cause. Wage and bank levies stop when the matter moves to CNC, IA, or OIC processing.

Outcomes vary. Past results do not guarantee future outcomes. Each tax case is unique.

Settlement ranges from the firm's case files

The following ranges come from Victory Tax Lawyers cases over the past several years and contribute to the firm's $100M+ aggregate tax-relief figure. Names and identifying facts are removed for confidentiality.

Matter type Original liability Resolution Approximate result
Installment Agreement $138,296 IRC §6159 streamlined IA $25/month accepted
Partial Pay IA $126,489 IRC §6159 PPIA through CSED $50/month accepted
Installment Agreement $128,206 IRC §6159 streamlined IA $25/month accepted
Partial Pay IA $116,451 IRC §6159 PPIA through CSED $50/month accepted
Installment Agreement $152,296 IRC §6159 streamlined IA $25/month accepted

Past results do not guarantee future outcomes. Each tax case is unique and turns on facts, asset position, monthly disposable income, IRS Allowable Living Expense tables, FTB equivalent standards, and the discretion of the assigned Revenue Officer, Settlement Officer, or FTB compromise reviewer. Acceptance rates for federal Offer in Compromise vary widely — the IRS reported a nationwide acceptance rate of roughly 30 to 40 percent in recent years.

Why work with a California-licensed firm on a Contra Costa County tax matter

A Contra Costa County tax matter rarely sits in a single forum. A federal RSU underwithholding bill on a Chevron executive at San Ramon triggers a parallel California assessment within four years through the federal-state information-exchange agreement. An EDD AB 5 audit on a Concord trucking or energy-services contractor often runs alongside an IRS Form 4180 interview for Trust Fund Recovery. An FTB residency audit on a retired AT&T executive who relocated from Lafayette to Nevada usually pulls in property records from the Contra Costa County Assessor in Martinez. These matters do not stay in their lanes.

Victory Tax Lawyers is admitted in California, headquartered in Los Angeles, and built around this overlap. Parham Khorsandi (Cal Bar #266658) and Amir Boroumand (Cal Bar #269570) appear directly before the FTB, CDTFA, EDD, and OTA, and on the federal side before the IRS and the U.S. Tax Court. The same attorneys handle the whole engagement — no Form 2848 workaround, no referral chain through out-of-state counsel.

California Rule of Professional Conduct 7.1 governs lawyer advertising in the state. No superlatives without verifiable substantiation, no specific dollar guarantees, no testimonials without disclaimers. The firm operates under those rules natively. This page does not promise outcomes, does not promote dollar averages, and does not list testimonials without context.

If your case is purely federal — an IRS audit, a Tax Court petition with San Francisco place of trial, an Offer in Compromise — we handle it under Tax Court bar admission, Circular 230, and a Form 2848 Power of Attorney. The California-licensed difference shows up when the state side appears, which it usually does.

The seven steps of a VTL tax-resolution engagement

1

Free consultation

A 30-minute call with an attorney to outline the facts, the IRS or FTB notices received, and realistic resolution options.

2

Engagement letter

A written attorney-client agreement defines scope, fee, and authority. California-bar privilege and federal common-law privilege both attach.

3

Federal & state PoA

Form 2848 filed with the IRS, FTB Form 3520, CDTFA Form 392, or EDD DE 48 filed with the relevant California agency. Notices route to counsel.

4

Transcript investigation

IRS Account Transcripts, Wage-and-Income Transcripts, and Record of Account pulled across all open years. FTB MyFTB, CDTFA, and EDD records pulled. Federal CSED and California 20-year statute dates verified.

5

Strategy memo

A written analysis recommending federal OIC, IA, CNC, audit response, CDP, or Tax Court petition with the FTB, CDTFA, or EDD parallel strategy where applicable.

6

Resolution filed

Federal Forms 656, 433-A, 9423, 12153, or Tax Court Petition. State FTB Form 4905, CDTFA offer, or EDD compromise. Negotiations with Revenue Officers, Settlement Officers, Appeals Officers, FTB analysts, CDTFA supervisors, and OTA hearings handled directly.

7

Compliance close-out

Post-resolution monitoring: quarterly estimates, return filings, and protection against IA default. The case is done when the new pattern is stable, not when the offer is accepted.

Collection statute warning — the California 20-year tail

Under IRC §6502(a), the IRS has ten years from the date of assessment to collect. After the federal Collection Statute Expiration Date, the debt becomes uncollectible by operation of law. Tolling events extend the federal CSED: a pending OIC (extends by OIC pendency plus 30 days), bankruptcy (extends by stay plus six months), Collection Due Process hearings, Innocent Spouse claims, and continuous absence from the United States for six months or more.

The California side is the opposite of forgiving. Under Cal. Rev. & Tax. Code §19255, the FTB has 20 years from the latest of assessment, due date, or final return filing to collect. That is double the federal CSED. CDTFA collection runs 10 years under §6711 with similar tolling. EDD operates under its own collection window in the Unemployment Insurance Code.

A federal balance assessed in 2016 may approach CSED expiration in 2026, while the FTB equivalent continues to be collectible until 2036. Submitting a federal OIC restarts the federal clock. Sometimes a Partial Pay IA that runs out the federal statute is the better federal play, paired with a separate FTB compromise to address the longer state tail. The two strategies are decided together.

Contra Costa County venue: federal and state tax forums

A Contra Costa County tax matter may proceed in any of several federal or state forums depending on the type of liability. Below are the offices, courthouses, and agencies serving the county.

U.S. Tax Court — San Francisco trial sessions

The United States Tax Court holds San Francisco trial sessions at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco CA 94102. A Contra Costa County petitioner designates "San Francisco, California" as the place of trial on the petition under Tax Court Rule 140.

IRS Walnut Creek Taxpayer Assistance Center

The IRS operates a TAC at 1301 S. California Boulevard, Suite 102, Walnut Creek CA 94596 — the closest TAC to most Contra Costa County residents. Appointments through apps.irs.gov/app/office-locator or 844-545-5640.

U.S. District Court (Northern District of CA)

Federal refund suits and criminal-tax cases proceed in the U.S. District Court for the Northern District of California, headquartered at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco. Appellate review goes to the Ninth Circuit in San Francisco.

Contra Costa County Superior Court

State-tax civil collection actions and probate-tax matters proceed at the Contra Costa County Superior Court Wakefield Taylor Courthouse, 725 Court Street, Martinez CA 94553. The court also hears the family-law matters that intersect with joint federal liability allocation.

Contra Costa County Treasurer-Tax Collector

The Contra Costa County Treasurer-Tax Collector handles property-tax billing and collection at 625 Court Street, Room 100, Martinez CA 94553. Property-tax delinquencies on Lamorinda, Alamo, Danville, and Diablo real estate proceed through this office.

Contra Costa County Assessor

The Contra Costa County Assessor at 2530 Arnold Drive, Suite 100, Martinez CA 94553 administers property valuation under Prop 13 / Prop 19 and records federal NFTLs and FTB State Tax Liens against Contra Costa County real property.

California FTB Oakland field office

The California Franchise Tax Board Oakland field office serves Contra Costa County. We appear there on residency audits, Notice of Action protests, and FTB compromise filings under Cal. Rev. & Tax. Code §19443.

Cities & service area

Contra Costa County contains 19 incorporated cities: Concord, Richmond, Antioch, Walnut Creek, Pittsburg, San Ramon, Brentwood, Pleasant Hill, Martinez (county seat), Hercules, Oakley, Lafayette, San Pablo, Pinole, Orinda, Moraga, Danville, Clayton, and El Cerrito. Unincorporated areas include Alamo, Diablo, Discovery Bay, Bay Point, and Kensington. We represent clients across all of them.

Request a free consultation with a Contra Costa County tax attorney

A 30-minute call with an attorney costs nothing. Bring your most recent IRS notice, last filed federal and California returns, any FTB or CDTFA or EDD correspondence, and — if you are a Chevron, AT&T, or Bishop Ranch executive — your equity grant agreements and most recent vest statement. We will tell you which resolution options fit your facts on both sides before you sign anything.

Principal office: 1100 S. Robertson Boulevard, Los Angeles, CA 90035. Statewide California service including all 19 cities of Contra Costa County.
