Orange County taxpayers facing IRS or FTB collection: here is what shifted in 2026

Three pressures hit Orange County filers harder than the statewide average this cycle. First, Newport Beach and Irvine real-estate transactions hit by the post-2023 commercial-property reset are generating Section 1031 exchange examinations where the IRS challenges identification timing under IRC §1031(a)(3) and the 45-day / 180-day windows. Second, the IRS resumed full passport-revocation referrals under IRC §7345 for federal balances above $62,000 — a serious problem for the Persian-American and Vietnamese-American business owners in the county who travel internationally. Third, FBAR enforcement under 31 USC §5314 ramped back up after the Bittner Supreme Court decision; Orange County's diaspora-heavy population has unusually high foreign-account exposure, and FTB residency audits at Cal. Rev. & Tax. Code §17014 hit departing residents heading to Nevada and Texas particularly hard.

A California firm representing Orange County taxpayers across all 34 cities

Victory Tax Lawyers, LLP is a California-licensed tax-law firm with its principal office at 1100 S. Robertson Boulevard in Los Angeles, roughly 45 minutes up the 405 from Newport Beach and Irvine. Both of our attorneys hold the State Bar of California license in active standing — Parham Khorsandi, Cal Bar #266658, and Amir Boroumand, Cal Bar #269570 — and both are admitted to practice before the United States Tax Court. Because we are California-admitted, we appear directly before the FTB, CDTFA, EDD, and the California Office of Tax Appeals on behalf of Orange County clients. No referral-out, no co-counsel arrangement.

Orange County has its own tax-controversy profile. The county hosts roughly 3.1 million residents across 34 incorporated cities, anchored by Santa Ana as county seat and by major population centers in Anaheim, Irvine, Huntington Beach, Garden Grove, Orange, Fullerton, and Costa Mesa. The Irvine Spectrum corridor concentrates technology employment; Newport Beach and Costa Mesa hold a dense cluster of private-equity firms, wealth managers, and family offices; Anaheim hosts the Disneyland tourism economy; and the Little Saigon area straddling Westminster and Garden Grove is the largest Vietnamese-American community outside Vietnam. Each of these communities walks in the door with different tax problems.

For Newport Beach and Irvine clients in real estate, the work is partnership taxation under IRC §707 disguised-sale rules, IRC §704(b) substantial-economic-effect testing, IRC §1031 like-kind exchange examinations, and carried-interest planning under IRC §1061. For Little Saigon and the Persian-American community in Newport Coast and Irvine, the work is often FBAR delinquency under 31 USC §5314, the FinCEN Form 114 streamlined filing compliance procedures, and IRC §6038D Form 8938 specified foreign financial asset reporting. For Anaheim and Santa Ana small-business owners, the work is more often Trust Fund Recovery Penalty defense, EDD AB 5 worker-classification audits, and CDTFA cash-business sales-tax determinations.

The rest of this page lays out the federal and California overlap as it applies to Orange County specifically: the courthouses where these matters are heard, the IRS Taxpayer Assistance Center serving the county, the County Treasurer-Tax Collector and Assessor offices that handle Orange County property-tax exposure, and the specific FTB, CDTFA, and EDD pressure points that hit OC filers.

Your tax rights as an Orange County taxpayer

Federal taxpayer rights are codified across the Internal Revenue Code and summarized in IRS Publication 1, the Taxpayer Bill of Rights. California layers its own taxpayer-rights regime on top, primarily through the FTB Taxpayer Bill of Rights at Cal. Rev. & Tax. Code Part 10.7 and parallel provisions for CDTFA and EDD. The major rights you can invoke in a Orange County tax matter:

Right to representation (federal)

Under IRC §7521(b)(2), an IRS examiner or collection officer must suspend an interview if you state you wish to consult an authorized representative. A signed Form 2848 puts your tax attorney between you and the IRS for the remainder of the matter. The IRS Santa Ana Taxpayer Assistance Center honors this immediately at the in-person counter.

Right to representation (California)

FTB Form 3520-PIT (or 3520-BE for entities) appoints a representative with full authority before the Franchise Tax Board. CDTFA Form 392 and EDD DE 48 do the same for sales-tax and payroll matters. Once filed, all FTB Santa Ana field-office notices route to counsel.

Right to Collection Due Process

After a Notice of Federal Tax Lien (IRC §6320) or a Final Notice of Intent to Levy (IRC §6330), you have 30 days to request a Collection Due Process hearing on Form 12153. CDP requests pause federal collection enforcement and preserve U.S. Tax Court review.

Right to OTA appeal

Effective 2018 under AB 102, the California Office of Tax Appeals hears appeals from FTB, CDTFA, and EDD determinations. The appeal window is 30 days from the Notice of Action for FTB matters. Orange County cases are heard at the OTA Los Angeles location at 355 S. Grand Avenue.

Right to U.S. Tax Court review

A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Orange County petitioners typically designate Los Angeles as the place of trial — the closest Tax Court trial city — held at the Edward R. Roybal Federal Building at 255 E. Temple Street. There is no separate Tax Court trial location in Orange County.

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 has compromise authority under Cal. Rev. & Tax. Code §19443. CDTFA operates a parallel offer program under Cal. Rev. & Tax. Code §6832. EDD compromise authority sits at Cal. Unemp. Ins. Code §1192. Each program has its own form, financial-disclosure standard, and review track.

Right to a Collection Statute

IRC §6502 gives the IRS 10 years from assessment to collect. California's parallel period under Cal. Rev. & Tax. Code §19255 is 20 years — double the federal CSED. Pull both transcripts before negotiating.

How Victory Tax Lawyers helps Orange County taxpayers

Federal & California Offer in Compromise

We prepare and file federal Form 656 with Form 433-A(OIC) under IRC §7122, and FTB Form 4905 PIT or BE with the parallel California financial under Cal. Rev. & Tax. Code §19443. The two reviews run in parallel but use different Reasonable Collection Potential math. California is harder on equity in primary residences than the IRS — a real factor when the residence is a Newport Beach property with substantial appreciation.

Installment Agreements (IRS & FTB)

Streamlined IRS IAs under $50,000, Non-Streamlined IAs over $50,000 with Form 433-F disclosure, and Partial Pay Installment Agreements under IRC §6159 that run only through the CSED. FTB monthly-payment plans under FTB Form 3567. CDTFA and EDD have their own payment structures.

Lien release and withdrawal

A federal Notice of Federal Tax Lien under IRC §6321 and an FTB State Tax Lien under Cal. Gov. Code §7170 both attach to Orange County real and personal property and record at the Orange County Clerk-Recorder in Santa Ana. We pursue release after payment, certificate of discharge for refinancing or sale, subordination, and lien withdrawal under the Fresh Start program for IAs under $25,000.

Levy release (IRS, FTB, EDD)

Federal wage levies (CP90 / LT11) and bank levies under IRC §6331 stop with CNC, an accepted IA, an accepted OIC, or a CDP request. 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 bank levies hold 10 business days. The clock matters.

Audit and exam defense

Federal correspondence, office, and field audits. FTB residency audits under Cal. Rev. & Tax. Code §17014 — especially common after a move from Newport Coast or Coto de Caza to Henderson or Austin. CDTFA sales-tax audits aimed at Anaheim and Santa Ana cash businesses. EDD AB 5 worker-classification audits hitting Irvine consulting firms and construction trades.

Penalty abatement

Federal First-Time Penalty Abatement and reasonable-cause requests under IRC §6651. FTB penalty waivers under Cal. Rev. & Tax. Code §19131 (failure to file) and §19132 (failure to pay), and CDTFA waivers under §6592. Reasonable-cause for OC filers affected by the 2018 Holy Fire, 2020 Silverado and Bond Fires, and the 2025 Airport Fire.

12 types of Orange County tax issues we handle

Federal and California state practice areas, framed for the matters that actually walk in the door from Newport Beach, Irvine, Santa Ana, Anaheim, Costa Mesa, Westminster, Garden Grove, and the rest of the county.

1031 like-kind exchange audits

Newport Beach and Irvine investor exchanges challenged on the 45-day identification deadline, 180-day closing deadline, related-party rules under IRC §1031(f), and qualified-intermediary structure. The 2017 TCJA limited §1031 to real property; personal-property exchanges still in audit pipelines remain a problem.

Carried-interest and partnership tax

Costa Mesa and Newport Beach private-equity and venture partnerships under IRC §1061 three-year holding rule, §707 disguised-sale exposure, and §704(b) substantial-economic-effect testing. The 2017 TCJA tightened carried-interest treatment; California treats the same income as ordinary at the 13.3 percent rate.

FBAR and foreign-account disclosure

Persian-American clients in Newport Coast, Irvine, and Mission Viejo, and Vietnamese-American clients in Westminster and Garden Grove, with accounts in Iran, Vietnam, Hong Kong, the UAE, and Singapore. FinCEN Form 114 under 31 USC §5314, Form 8938 under IRC §6038D, and the Streamlined Domestic Offshore Procedures.

FTB residency audits

The nine-factor domicile test under Cal. Rev. & Tax. Code §17014 and FTB Pub. 1031. Common after moves from Coto de Caza, Newport Coast, Yorba Linda, and Laguna Beach to Henderson, Austin, Naples, or Bellevue. We document driver's-license changes, voter registration, real-property transfers, and physical-presence days.

Trust Fund Recovery Penalty

Under IRC §6672, the IRS pierces the corporate veil for unpaid payroll trust funds. Anaheim restaurants, Santa Ana auto-repair shops, and Buena Park family-owned businesses that fell behind on Form 941 deposits often discover this through Form 4180 interviews.

EDD AB 5 worker-classification

Irvine consulting firms, real-estate brokerages, construction trades in Anaheim and Santa Ana, and beauty-services operators reclassified from 1099 to W-2 under the Dynamex ABC test now codified at Cal. Lab. Code §2775. Back UI, ETT, SDI, and PIT withholding for three years plus penalties.

CDTFA cash-business audits

Cash-intensive restaurants in Little Saigon, auto-body shops along Beach Boulevard, convenience stores, and dispensaries draw CDTFA mark-up audits using observation tests and POS reconciliation. Test-period methodology gets challenged before it scales statewide.

Wage and bank levies

IRS CP90 / LT11 levies, FTB Earnings Withholding Orders for Taxes (EWOT) under Cal. Rev. & Tax. Code §18670, CDTFA collector levies, and EDD wage garnishments. Move to release before the next payroll runs.

Federal and California tax liens

NFTLs filed with the California Secretary of State and the Orange County Clerk-Recorder in Santa Ana, and FTB State Tax Liens under Cal. Gov. Code §7170 et seq. Both cloud title on Orange County real property until released or withdrawn — a particular problem mid-escrow on a Newport Beach sale.

Passport revocation defense

IRC §7345 certifications to the State Department. We work to decertify before travel for Irvine tech executives, Newport Beach finance professionals, Persian-American business owners with cross-border commerce, and Vietnamese-American clients with annual family travel.

Equity compensation back taxes

Irvine Spectrum tech employees with ISO exercises into Alternative Minimum Tax exposure under IRC §55 and RSU vest spikes at biotech and aerospace employers along the 405 corridor. Multi-state allocation for employees who changed residency mid-vest.

Innocent Spouse Relief

Federal Form 8857 relief under IRC §6015 and California parallel relief under Cal. Rev. & Tax. Code §18533. California is a community-property state under Cal. Fam. Code §760 — the analysis is fact-heavy, especially in Orange County divorces involving a closely-held business.

Nine common causes of tax debt in Orange County

1. Investment-property gains without 1031

Orange County saw aggressive 2020-2023 commercial and multi-family appreciation. Investment-property sales without a properly executed like-kind exchange under IRC §1031 triggered surprise federal capital gains plus California's 13.3 percent treatment of capital gains as ordinary income.

2. Carried-interest holding-period misses

Costa Mesa and Newport Beach private-equity partners caught by the three-year holding requirement at IRC §1061. A sale inside the window converts what would have been long-term capital gain into ordinary income, with California then layering its top rate on the entire amount.

3. FBAR and Form 8938 omissions

Persian-American and Vietnamese-American families with inherited or family-business accounts in the home country who did not realize the U.S. reporting obligation. Bittner v. United States (2023) capped non-willful penalties per form per year, but willful exposure remains the greater of $129,210 or 50 percent of the account.

4. Departing-resident FTB audits

High earners who moved from Orange County to Nevada, Texas, Florida, or Washington routinely trip the FTB nine-factor domicile test. The FTB asserts continued California domicile for one to three additional tax years, generating substantial state-tax assessments after the move.

5. Tech equity compensation

An ISO exercise creates an AMT preference item even without a sale; RSU vests pile ordinary income onto a W-2. The April balance for Irvine Spectrum engineers, biotech R&D staff, and Aliso Viejo software employees routinely runs six figures.

6. ERC clawback exposure

Employee Retention Credit claims submitted by promoter mills are being clawed back through CP207/CP207L letters. Anaheim hospitality groups, Newport Beach professional-services firms, and Santa Ana medical and dental practices are inside the audit wave.

7. Small-business payroll lapses

An Anaheim restaurant, Westminster nail salon, Santa Ana auto shop, or Fullerton construction subcontractor stops depositing 941 trust funds during a slow quarter. The IRS asserts TFRP against the owner personally under IRC §6672, and EDD assesses parallel state payroll under Cal. Unemp. Ins. Code §1735.

8. Crypto trading without records

Irvine and Newport Beach hold heavy crypto-investor concentrations. Exchanges issued 1099-K and 1099-MISC reports; the IRS matches them to filed returns and issues CP2000 notices for the gap. FTB pursues the parallel California assessment using the federal data.

9. Wildfire-disrupted filing

Filers in the 2018 Holy Fire (Trabuco Canyon area), 2020 Silverado and Bond Fires (Foothill Ranch, Lake Forest), and 2025 Airport Fire (Trabuco Canyon, El Toro) zones missed deadlines. Disaster-zone extensions help, but penalty stacks accumulate fast when the disaster window lapses.

Who is on the hook: eight Orange County tax-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 after divorce — subject to Innocent Spouse Relief under IRC §6015 and Cal. Rev. & Tax. Code §18533. Especially relevant in Newport Beach high-asset divorces.

Partnership general partners

Under IRC §6231 and the BBA centralized partnership audit regime, general partners of Newport Beach and Costa Mesa real-estate and PE partnerships face imputed underpayment liability for partnership-level adjustments. Push-out elections under IRC §6226 shift the burden to the partners' year of audit.

Responsible persons for payroll

Trust Fund Recovery Penalty under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes. State parallel sits at Cal. Unemp. Ins. Code §1735 for EDD payroll. Reaches Anaheim, Santa Ana, and Garden Grove small-business owners after the entity folds.

CDTFA dual-determinations

CDTFA issues dual-determination notices personally against corporate officers, directors, and LLC members of entities that fail to remit sales tax in trust, under Cal. Rev. & Tax. Code §6829. Common against Little Saigon restaurant operators after the business closes.

FTB suspended-entity personal exposure

An entity that fails to pay California minimum franchise tax or file a Statement of Information is suspended by FTB under Cal. Rev. & Tax. Code §23301. While suspended, the entity loses its right to contract, sue, or defend in California courts — including the Orange County Superior Court. Officers signing on behalf during suspension can incur personal exposure.

Transferee liability

IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Orange County family-LLC restructurings, Prop 19 child-to-parent transfers under Cal. Const. Art. XIII A, and intra-family trust funding moves can trigger this analysis.

Successor business liability

Asset purchases of an Orange County restaurant, manufacturing operation, or auto-dealership can carry forward CDTFA sales-tax successor liability under Cal. Rev. & Tax. Code §6811-6814 and EDD payroll successor liability under Cal. Unemp. Ins. Code §1731. Clearance letters from CDTFA and EDD before close are the buyer's protection.

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. Personal liability for the executor attaches under 31 USC §3713(b) if distributions are made before federal tax claims are satisfied. Probate of high-asset Orange County estates moves through the Orange County Superior Court Probate division.

What resolution can look like in Orange 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.

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 Holy Fire, Silverado/Bond Fire, and Airport Fire disaster periods, serious illness, and preparer reliance. FTB waivers under §19131 and §19132 follow parallel principles.

Liens and levies released

A federal NFTL withdraws once a streamlined IA is in place under Fresh Start. FTB State Tax Liens release on payment, accepted compromise, or release-for-cause — critical when refinancing or selling Orange County real property. Wage and bank levies stop when the account moves to CNC, IA, or OIC processing. Passport certifications reverse once federal debt drops below the §7345 threshold.

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 an Orange County tax matter

Orange County taxpayers deal with two tax systems that interact in ways most out-of-state firms do not understand. A residency adjustment at the FTB can trigger a federal income re-allocation. A federal NFTL filed with the Orange County Clerk-Recorder sits in the same recording index as the FTB's own State Tax Lien against the same Newport Beach or Irvine property. An IRS Form 4180 interview on an unpaid 941 trust fund often runs in parallel with an EDD payroll audit and a CDTFA sales-tax determination on the same Anaheim or Santa Ana business. The matters do not stay in their lanes.

Victory Tax Lawyers is California-admitted, headquartered in Los Angeles, and built around exactly this overlap. Parham Khorsandi (Cal Bar #266658) and Amir Boroumand (Cal Bar #269570) appear directly before the FTB, CDTFA, EDD, and the California Office of Tax Appeals, and on the federal side before the IRS and the U.S. Tax Court. No out-of-state coordination, no Form 2848 workaround. The same attorneys handle the whole engagement from initial Form 12153 through final Tax Court trial in Los Angeles.

California is one of the most lawyer-intensive tax environments in the country. The State Bar's Rule of Professional Conduct 7.1 (formerly Rule 1-400) tightly 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, which is why this page does not promise outcomes, does not promote dollar averages without context, and does not list testimonials without proper disclosure.

Orange County is also unusual for the diaspora-driven volume of foreign-account, partnership-tax, and high-asset divorce matters that show up in the practice. We see more FBAR work from Newport Coast and Westminster than from any other county in California outside Los Angeles. We see more 1031 exchange and carried-interest work from Newport Beach and Costa Mesa than from any other zip clusters in the state. That practice density shapes how we approach an Orange County engagement.

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 the realistic resolution options for an Orange County matter.

2

Engagement letter

A written attorney-client agreement defines scope, fee, and authority. California-bar privilege and federal common-law attorney-client 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. All 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 account, CDTFA records, 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 on either side. 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 generally has ten years from the date of assessment to collect a tax. After the federal Collection Statute Expiration Date, the debt becomes uncollectible by operation of law. Tolling events that extend the federal CSED include a pending Offer in Compromise (extends by OIC pendency plus 30 days), bankruptcy filing (extends by bankruptcy stay plus six months), Collection Due Process hearings (extends while pending), Innocent Spouse claims, and continuous absence from the United States for six months or more — relevant for Orange County clients with international family commitments.

The California side is the opposite of forgiving. Under Cal. Rev. & Tax. Code §19255, the FTB has 20 years from the latest of the assessment, the date the liability becomes due and payable, or the date a final return was filed, to collect. That is double the federal CSED. CDTFA collection statutes for sales-and-use tax are governed by Cal. Rev. & Tax. Code §6711, generally 10 years from determination but with similar tolling. EDD has its own collection window under Cal. Unemp. Ins. Code §1701.

The practical impact for an Orange County filer: a federal balance assessed in 2016 may be approaching 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, not in isolation.

Orange County venue: where federal and state tax matters are heard

Federal tax matters affecting Orange County taxpayers proceed in federal venues, almost all of which sit within Los Angeles County for OC filers. State matters at the FTB, CDTFA, and EDD that reach a formal appeal proceed through the California Office of Tax Appeals, with judicial review available in the Orange County Superior Court for certain collection actions.

U.S. Tax Court — Los Angeles trial sessions

There is no U.S. Tax Court trial location in Orange County. Orange County petitioners typically designate Los Angeles as the place of trial under Tax Court Rule 140; sessions are held at the Edward R. Roybal Federal Building at 255 E. Temple Street, Los Angeles — roughly 35 to 45 miles from Newport Beach, Irvine, Santa Ana, and Anaheim depending on starting point. San Diego is also a designated trial city for OC petitioners closer to the southern county line.

IRS Taxpayer Assistance Center — Santa Ana

The closest IRS TAC for most Orange County taxpayers is the Santa Ana office at 34 Civic Center Plaza, Santa Ana 92701, in the federal building complex adjacent to the Ronald Reagan Federal Building. Appointments are required and arranged through apps.irs.gov/app/office-locator or 844-545-5640. The TAC handles in-person account inquiries, payment intake, identity verification, and ITIN applications.

Orange County Treasurer-Tax Collector

The Orange County Treasurer-Tax Collector at 12 Civic Center Plaza, Room 100, Santa Ana 92701 administers Orange County property-tax billing, collection, defaulted-property auctions, and unsecured-roll collections under California Revenue and Taxation Code. Property-tax delinquencies on Orange County real property — including those triggered by Prop 13 reassessment changes — route through this office.

Orange County Assessor

The Orange County Assessor at 500 S. Main Street, Second Floor, Orange 92868 sets Prop 13 base-year value and annual assessed value for every parcel in the county. Prop 19 parent-to-child reassessment exclusions, Prop 8 decline-in-value applications, and assessment appeals to the Orange County Assessment Appeals Board start here. A South County branch operates in Mission Viejo.

Orange County Superior Court

The Orange County Superior Court Central Justice Center at 700 Civic Center Drive West, Santa Ana 92701 handles state-tax civil actions, FTB and CDTFA collection litigation, judicial review of OTA decisions, probate proceedings with tax components, and divorce matters involving community-property tax allocation. Additional justice centers in Newport Beach (Harbor), Fullerton (North), Westminster (West), and Laguna Niguel (South) handle regional dockets.

FTB Santa Ana field office

The California Franchise Tax Board operates a Santa Ana field office serving Orange County residents and businesses. Personal-income-tax audits, residency examinations under Cal. Rev. & Tax. Code §17014, and corporate franchise-tax matters under Part 11 route through here. Headquarters at 9646 Butterfield Way, Sacramento.

U.S. District Court — Central District of California

Orange County sits in the U.S. District Court for the Central District of California (Southern Division). Federal refund suits and criminal-tax cases involving OC defendants proceed at the Ronald Reagan Federal Building and U.S. Courthouse at 411 W. 4th Street, Santa Ana 92701. Appellate review goes to the U.S. Court of Appeals for the Ninth Circuit in San Francisco.

California Office of Tax Appeals

The California Office of Tax Appeals was created in 2018 under AB 102 to hear appeals from FTB, CDTFA, and EDD determinations. Orange County matters are heard at OTA Los Angeles at 355 S. Grand Avenue. Three-judge panels of Administrative Law Judges; decisions are precedential and published. Hearings also held in Sacramento and Fresno.

VTL represents clients in all 34 incorporated cities of Orange County, including Santa Ana, Anaheim, Irvine, Huntington Beach, Garden Grove, Orange, Fullerton, Costa Mesa, Mission Viejo, Westminster, Newport Beach, Buena Park, Tustin, Yorba Linda, San Clemente, Laguna Niguel, Lake Forest, Cypress, La Habra, Aliso Viejo, Fountain Valley, Placentia, Rancho Santa Margarita, Brea, Stanton, La Palma, Seal Beach, Laguna Hills, Laguna Beach, Dana Point, Los Alamitos, Villa Park, and the unincorporated areas including Coto de Caza, Ladera Ranch, and Rossmoor.
