Napa County taxpayers facing IRS or FTB collection — what changed in 2026
Three matters drive Napa Valley filings this cycle. First, IRS Examination remains focused on winery UNICAP capitalization under IRC §263A — multi-year barrel aging is the textbook application of the uniform capitalization rules, and Napa wineries with multi-vintage cellar inventories continue to draw correspondence and field exams. Second, the 2017 Atlas Fire, 2017 Tubbs Fire incursion at the Sonoma line, the 2020 LNU Lightning Complex, and the 2020 Glass Fire produced insurance recoveries and replacement-property timing questions that the IRS is still working through under IRC §1033 involuntary-conversion deferral. Third, the Franchise Tax Board continues to pursue Napa County residents who moved to Nevada, Texas, Tennessee, or Idaho under the nine-factor domicile test at Cal. Rev. & Tax. Code §17014, with a retained estate vineyard or a Napa second-home treated as a strong domicile indicator.

A California law firm serving Napa County and the Napa Valley
Napa County is the premier wine-producing region in the United States and the densest concentration of estate-winery, hospitality, and viticultural-tax practice anywhere in the country. The county covers roughly 750 square miles between the Mayacamas Range to the west and the Vaca Range to the east, running about thirty miles north-to-south from San Pablo Bay up to Mount Saint Helena. Inside that footprint sit 16 federally recognized American Viticultural Areas, including the Napa Valley AVA itself plus sub-AVAs at Rutherford, Oakville, Stags Leap District, Mount Veeder, Spring Mountain District, Howell Mountain, Atlas Peak, Diamond Mountain District, Yountville, Oak Knoll District, St. Helena, Calistoga, Coombsville, Wild Horse Valley, Chiles Valley, and Los Carneros. More than 400 bonded wineries operate within the county, including names that built the modern California wine industry — Robert Mondavi, Caymus, Opus One, Stag's Leap Wine Cellars, Beringer, Domaine Chandon, Inglenook, Schramsberg, Trefethen, Cakebread, Joseph Phelps, Spottswoode, and hundreds of smaller estate and custom-crush operations.
Five incorporated cities cover the county: the City of Napa as the county seat at the south end of the valley, American Canyon along the Highway 29 corridor between Napa and Vallejo, Yountville in the heart of the valley floor, St. Helena in the upvalley AVAs, and Calistoga at the north end near Mount Saint Helena. Unincorporated communities anchor the valley's working agriculture and hospitality footprint — Oakville and Rutherford on the valley floor, Pope Valley and Chiles Valley in the eastern hills, Angwin on Howell Mountain, Deer Park north of St. Helena, and the Carneros lowlands shared with Sonoma County. Tourism and hospitality anchor a second economic pillar alongside wine, with destination resorts such as Auberge du Soleil in Rutherford and Meadowood in St. Helena drawing visitors year-round. The Veterans Home of California in Yountville is one of the largest veterans' residential facilities in the country.
Victory Tax Lawyers is a California-licensed tax-law firm headquartered at 1100 S. Robertson Boulevard in Los Angeles. Both attorneys are members of the State Bar of California in active standing: Parham Khorsandi, Cal Bar #266658, and Amir Boroumand, Cal Bar #269570. Both are admitted to practice before the United States Tax Court.
California is our home jurisdiction. That matters in Napa County, where a single client engagement routinely touches the IRS (winery Schedule F, UNICAP capitalization under IRC §263A, alcohol federal-excise coordination with the TTB, federal disaster-relief filings tied to multiple FEMA declarations), the FTB (state income tax, residency for out-of-state moves with a retained Napa vineyard or estate), CDTFA (sales tax on tasting-room retail, restaurant operations, alcohol delivery and direct-shipment compliance), EDD (worker classification for vineyard crews, harvest contractors, and hospitality staff under AB 5), and Napa County Superior Court (Williamson Act and Prop 13 property-tax assessment-appeal litigation, divorce-tax allocation on vineyard estates, multigenerational winery probate). Wildfire recovery overlays nearly every active file — Atlas Fire 2017, the Tubbs Fire spillover at the Sonoma County line, the LNU Lightning Complex and Glass Fire in 2020, and ongoing rebuild work that produces insurance proceeds, §1033 elections, and casualty-loss filings the IRS is still examining.
If you have a federal tax problem, a California tax problem, or both, and you live or operate in Napa County, this is the page for you. The rest of it lays out who collects, where matters get heard, and what resolution actually looks like in this county.
Your tax rights as a Napa 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 through the FTB Taxpayer Bill of Rights at Cal. Rev. & Tax. Code Part 10.7 and parallel provisions for CDTFA and EDD. The rights you can invoke from anywhere in Napa County — whether from a Rutherford tasting room, an estate winery on Howell Mountain, or a hospitality kitchen in downtown Napa:
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 places counsel between you and the IRS for the rest of the matter — whether you operate in Stags Leap District, Oakville, Mount Veeder, or Calistoga.
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-tax matters. Once filed, all 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 CDP hearing on Form 12153. CDP requests pause federal collection enforcement and preserve U.S. Tax Court review.
Right to disaster-zone postponement
Under IRC §7508A, the IRS may postpone deadlines for taxpayers in federally declared disaster areas. Napa County qualified under multiple FEMA declarations for the 2017 Atlas Fire, the 2020 LNU Lightning Complex, the 2020 Glass Fire, and subsequent atmospheric-river winter storms. Postponement covers return filing, payment, refund-claim windows, and Tax Court petition deadlines.
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. OTA holds hearings in Sacramento, Los Angeles, and Fresno; Napa County appellants generally select the Sacramento hearing site as the closest panel.
Right to U.S. Tax Court review
A Notice of Deficiency triggers a 90-day petition window under IRC §6213(a). Napa County petitioners designate San Francisco as the place of trial — the U.S. Tax Court holds trial sessions at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco. Filing in Tax Court means you litigate without paying the deficiency first.
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. EDD compromise authority sits at Cal. Unemp. Ins. Code §1192. Each program has its own form, financial disclosure standard, and review path.
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 anything.
How Victory Tax Lawyers helps Napa County taxpayers
Federal & California Offer in Compromise
We prepare and file federal Form 656 with the supporting Form 433-A(OIC) under IRC §7122, and FTB Form 4905 PIT or BE with the parallel financial under Cal. Rev. & Tax. Code §19443. For a Napa County winery owner with estate vineyard ground in Rutherford, Oakville, or Stags Leap District, the federal and state Reasonable Collection Potential math diverges quickly — California pulls Napa Valley comparables for AVA-designated vineyard land that differ from how the IRS values agricultural land in revenue officer worksheets, and equity in tanks, barrels, presses, and bottling lines gets treated differently on each side.
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. For winery clients, the IA negotiation often turns on the multi-vintage cash-flow pattern — barrel-aging cash goes out years before tasting-room and direct-to-consumer revenue comes in, and a fixed monthly payment that ignores that cycle defaults faster than it should. FTB offers parallel monthly-payment plans under FTB Form 3567 that can be structured to match the operating year.
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 California real and personal property — recorded against Napa County parcels through the County Assessor-Recorder-County Clerk's office. We pursue release after payment, certificate of discharge for specific property (often needed for a vineyard sale or a refinance through American AgCredit, Silicon Valley Bank's wine division, or another regional ag lender), subordination for refinancing, and lien withdrawal under Fresh Start 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 for Taxes under Cal. Rev. & Tax. Code §18670 and bank levies under §18670.5 release under parallel resolutions. Federal bank levies hold for 21 days; FTB bank levies hold for 10 business days — the clock matters when the levy hits a tasting-room operating account or a winery's distributor-payment account on a Friday before harvest payroll.
Audit and exam defense
Federal correspondence, office, and field audits — including winery UNICAP examinations under IRC §263A (the textbook industry application of multi-year inventory capitalization), Schedule F farm-income examinations on vineyard operations, IRC §179 farm-equipment expensing on tractors and bottling lines, casualty-loss filings tied to Atlas Fire, LNU Lightning Complex, and Glass Fire damage under IRC §165(i), and TTB-coordinated federal excise issues. FTB residency audits under Cal. Rev. & Tax. Code §17014 (FTB Pub. 1031 nine-factor analysis), CDTFA sales-tax audits on tasting-room retail and direct-shipment compliance, and EDD worker-classification audits on vineyard labor crews, harvest contractors, and hospitality staff.
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). Disaster reasonable-cause for filers covered by FEMA declarations for the Atlas Fire, Tubbs Fire spillover, LNU Lightning Complex, Glass Fire, and subsequent atmospheric-river floods affecting Napa County.
12 types of Napa County tax issues we handle
Federal and California state practice areas, framed for the matters that actually walk in our door from Napa Valley.
Winery UNICAP examinations (IRC §263A)
Napa Valley wineries are the textbook application of IRC §263A — multi-year barrel aging of Cabernet Sauvignon and estate red blends drives years of capitalized barrel-aging interest, cellar labor, bottling, labeling, storage, and allocable overhead into the cost-of-goods schedule. The IRS examines Napa wineries for understated UNICAP, mis-aged inventory accounts, and Rev. Proc. 2002-9 method-change posture. We defend the capitalization schedule and the underlying cost-accounting records across multiple cellar vintages.
Schedule F vineyard-income examinations
Napa County grape growers and estate vineyards file Schedule F on the farming side and a separate winery entity return for the production-and-sales side. The IRS examines cash-versus-accrual reporting, prepaid-expense deductions limited under IRC §464, vineyard development costs subject to capitalization under IRC §263A(d), and the timing of bulk-grape and crush contract income under IRC §451.
Wildfire casualty loss & §1033 deferral
The 2017 Atlas Fire on Atlas Peak, the Tubbs spillover at the Sonoma line, and the 2020 LNU Lightning Complex and Glass Fire destroyed vineyards, wineries, and homes across the county. Insurance proceeds above adjusted basis create gain that can be deferred under IRC §1033 if replacement property is acquired within the statutory window (two to four years depending on circumstances). We file the election, track the replacement period for vine-replanting cycles, and defend the basis math when the IRS examines.
IRC §179 farm and winery equipment
Tractors, sprayers, harvest gondolas, presses, fermentation tanks, bottling lines, and labeling equipment qualify for IRC §179 first-year expensing within the annual limit, plus bonus depreciation under IRC §168(k) for items that remain. The IRS audits aggressive year-end equipment buys and listed-property usage allocations on shared trucks and SUVs.
TTB federal excise & alcohol-tax coordination
Napa County wineries pay federal alcohol excise tax to the Alcohol and Tobacco Tax and Trade Bureau (TTB) at the per-gallon rate set under 26 U.S.C. §5041. The Craft Beverage Modernization Act credit, bonded-warehouse compliance, and TTB-versus-IRS Schedule of Liabilities reconciliation regularly produce notices. We coordinate TTB matters with federal income-tax exposure on the same entity.
Vineyard labor & AB 5 classification
Farm labor contractors supplying crews to Napa Valley vineyards face EDD audits on whether crew members run W-2 through the FLC or through the grower. AB 5 and the ABC test at Cal. Lab. Code §2775 reach H-2A and domestic crews alike. Reclassification carries UI, ETT, SDI, and PIT withholding plus penalties — significant exposure for estate-vineyard operations across Rutherford, Oakville, and St. Helena.
Vineyard sale §1031 like-kind exchanges
A Napa Valley vineyard sale, often involving multimillion-dollar AVA-designated ground, can defer the federal capital-gain hit through an IRC §1031 like-kind exchange into replacement farmland. The 45-day identification period and 180-day closing window are unforgiving, and the qualified-intermediary structure has to be in place at the original closing. We unwind failed exchanges and structure new ones.
Brand and winery sale — §1060 + §197
An estate-winery sale typically allocates the purchase price among land, vineyard improvements, tanks and equipment, inventory in bottle and barrel, trademarks, customer lists, and goodwill under IRC §1060. Brand-related intangibles amortize over 15 years under IRC §197. Allocation choices drive seller capital-gain treatment and buyer depreciation schedules — the IRS audits aggressive allocation positions.
Hospitality & restaurant payroll trust funds
A St. Helena restaurant, a Yountville hospitality group, or a downtown Napa boutique hotel stops depositing Form 941 trust funds during a slow tourism quarter. The IRS asserts Trust Fund Recovery Penalty under IRC §6672 personally against the responsible person. EDD parallels under Cal. Unemp. Ins. Code §1735.
FTB residency audits (out-of-state moves)
Napa County residents who relocated to Nevada, Texas, Tennessee, or Idaho with a retained estate vineyard, a Napa Valley second-home, or family ties on the valley floor are textbook FTB residency-audit targets. The nine-factor domicile test under Cal. Rev. & Tax. Code §17014 and FTB Pub. 1031 weighs driver's-license, vehicle registration, voter registration, banking, family location, and physical-presence days.
Federal and California tax liens
NFTLs filed with the California Secretary of State and recorded with the Napa County Assessor-Recorder-County Clerk, and FTB State Tax Liens under Cal. Gov. Code §7170 et seq. Both cloud title on vineyard land, hospitality real estate, and residential property until released or withdrawn — a real obstacle to operating-line renewals at American AgCredit, Silicon Valley Bank's wine division, and other regional ag lenders.
Wage and bank levies (federal & state)
IRS CP90 / LT11 levies, FTB Earnings Withholding Orders for Taxes (EWOT) under Cal. Rev. & Tax. Code §18670, CDTFA collector levies, and EDD wage garnishments hit operating accounts, payroll runs, and personal accounts across the county. We move to release before the next harvest or hospitality payroll cycle.
Nine common causes of tax debt in Napa County
1. UNICAP understatement
Napa Valley wineries that fail to fully capitalize barrel-aging interest, cellar labor, and allocable overhead under IRC §263A produce understated inventory and overstated current deductions. Audit adjustments restore the capitalization and assess balances spanning multiple production vintages — particularly painful where a Cabernet program ages two-to-three years in barrel before release.
2. Wildfire insurance-proceed timing
Atlas Fire, LNU Lightning Complex, and Glass Fire insurance payouts received in one tax year for losses incurred in a prior year often miss the IRC §1033 election. Without the election and a documented replacement plan for vine-replanting, the entire gain hits in the year of receipt — often at the top federal bracket plus California's 13.3 percent.
3. Tasting-room and DTC sales tax
CDTFA audits Napa County tasting rooms and direct-to-consumer wine shippers on sales tax remitted on wine, retail merchandise, and food. Out-of-state direct shipments add interstate-tax complexity under Granholm-era state regimes and the 2019 Wayfair economic-nexus rules.
4. Hospitality payroll lapses
A Yountville restaurant, a St. Helena boutique hotel, or a Calistoga resort stops depositing Form 941 trust funds during a tourism downturn or a fire-suppressed visitor season. The IRS asserts TFRP under IRC §6672, and EDD assesses parallel state payroll under Cal. Unemp. Ins. Code §1735.
5. Out-of-state move and FTB pursuit
Residents who moved to Nevada, Texas, Tennessee, or Idaho often trip the FTB nine-factor domicile test — especially when an estate vineyard, a Napa Valley second-home, or family is left behind. FTB asserts that California domicile continued for one to three additional tax years.
6. ERC clawback exposure
Employee Retention Credit claims pushed by promoter mills are being clawed back through CP207 and CP207L letters. Napa County wineries, tasting rooms, restaurants, hotels, and hospitality vendors are part of the audit wave.
7. Bulk-grape sale income spikes
A strong vintage with cash-method bulk-grape sales clusters in one tax year — Napa Cabernet contracts often carry the highest per-ton prices in California. Without an IRC §1301 farmer income-averaging election or a deferred-payment crush contract, the grower kicks into the top federal bracket plus California 13.3 percent plus the §17043 MHSA 1 percent surtax above $1 million.
8. Brand sale allocation disputes
An estate-winery brand sale produces purchase-price allocation issues under IRC §1060 across land, equipment, inventory, trademark, customer lists, and goodwill. The IRS audits aggressive allocations that push value to inventory (ordinary) versus goodwill (capital gain) and the §197 amortization treatment on the buyer side.
9. Short-term-rental misreporting
Napa Valley short-term-rental hosts on Airbnb and VRBO often miss the Schedule C/E distinction, the IRC §280A vacation-home rules, and Napa County Transient Occupancy Tax registration. Misreported gross receipts and missed Form 1099-K reconciliation generate CP2000s and CDTFA notices.
Who is on the hook: eight Napa 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 filed at the Napa County Superior Court — subject to Innocent Spouse Relief under IRC §6015 and Cal. Rev. & Tax. Code §18533.
Responsible persons for winery and hospitality payroll
Trust Fund Recovery Penalty under IRC §6672 reaches anyone with check-signing authority who willfully failed to pay over withheld taxes — the FICA and federal income-tax-withholding portion of Form 941. The state parallel sits at Cal. Unemp. Ins. Code §1735 for EDD payroll-tax personal liability. Common in winery, tasting-room, restaurant, and boutique-hotel ownership across the valley.
CDTFA dual-determinations
CDTFA can issue dual-determination notices personally against corporate officers, directors, and LLC members that fail to remit sales tax in trust, under Cal. Rev. & Tax. Code §6829. Tasting rooms, restaurants, retail, and direct-to-consumer wine shippers in Napa, Yountville, Rutherford, St. Helena, Calistoga, and American Canyon draw these.
FTB suspended-entity personal exposure
An entity that fails to pay California minimum franchise tax or file a Statement of Information is suspended under Cal. Rev. & Tax. Code §23301. The entity loses its right to contract, sue, or defend in California courts — and officers signing on its behalf may incur personal exposure. Common for Napa vineyard LLCs and hospitality entities that fall behind on $800 minimum franchise tax filings.
Transferee liability (federal & state)
IRC §6901 reaches a transferee of assets where the transfer rendered the transferor insolvent and tax debts remain unpaid. Family-LLC vineyard restructurings, Prop 19 parent-to-child transfers of Napa Valley agricultural real estate, and trust-funding moves that put estate-vineyard or tasting-room land into the next generation's name can trigger this.
Successor business liability
Asset purchases where the buyer continues the seller's California operations 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 protect buyers in winery, tasting-room, restaurant, hotel, and retail acquisitions — critical in the active Napa estate-winery M&A market.
Nominee and alter-ego
The IRS files a nominee or alter-ego lien when assets titled in another's name actually belong to the taxpayer. Common in Napa Valley asset-protection structures using family-limited partnerships, irrevocable trusts, and out-of-state LLC layering — particularly when vineyard ground or estate-winery improvements have been moved between related entities.
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. California Probate Code §9000 governs state-tax claim priority in probate at Napa County Superior Court — particularly important for multigenerational winery transitions with Section 2032A special-use valuation issues.
What resolution can look like in Napa 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 a winery or hospitality operation stabilizes through a fire-suppressed season or a tourism downturn.
Penalties abated
Federal First-Time Penalty Abatement removes failure-to-file and failure-to-pay penalties for a clean compliance year. Reasonable-cause requests cover Atlas Fire, LNU Lightning Complex, and Glass Fire evacuations, smoke-tainted vintages, atmospheric-river flooding, serious illness, and preparer reliance. FTB waivers under §19131 and §19132 follow parallel principles.
Liens and levies released
A federal NFTL recorded with the Napa County Assessor-Recorder-County Clerk withdraws once a streamlined IA is in place under Fresh Start. FTB State Tax Liens release on payment, accepted compromise, or release-for-cause. Wage and bank levies stop when the underlying account moves to CNC, IA, or OIC processing on either side — critical before operating-line renewal at the ag lender.
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 Napa County tax matter
Napa County tax matters sit in a particular spot. Federal venue runs through San Francisco for both U.S. Tax Court (Phillip Burton Federal Building, 450 Golden Gate Avenue) and the U.S. District Court for the Northern District of California, San Francisco Division. The IRS Taxpayer Assistance Center for Napa County is at 1041 Jefferson Street, Suite 1, Napa, CA 94559 — one of the few federal walk-in points inside the county. California state tax appeals at the FTB, CDTFA, and EDD level proceed through the California Office of Tax Appeals; Napa County appellants generally select Sacramento as the closest of the three OTA hearing sites. County-administered property tax happens at the Napa County Treasurer-Tax Collector at 1195 Third Street, Suite 108, Napa, and valuation proceedings run through the Napa County Assessor at 1127 First Street, Room E.
The Napa Valley overlay produces federal-tax issues at a density unmatched elsewhere in the country: winery UNICAP capitalization under IRC §263A on multi-vintage barrel-aged inventories, IRC §1033 wildfire involuntary-conversion deferrals on Atlas Fire and Glass Fire losses with vine-replanting cycles that stretch the replacement period, IRC §179 farm-and-winery equipment expensing, IRC §1301 farmer income averaging on vintage-driven income swings, IRC §1060 brand-sale purchase-price allocation, IRC §197 trademark and goodwill amortization, TTB-coordinated federal alcohol excise issues, and ongoing FEMA-declared disaster postponements under IRC §7508A. On the California side, FTB residency audits for out-of-state moves with retained valley ground, CDTFA sales-tax issues on tasting-room and DTC wine shipments, and EDD AB 5 audits on vineyard labor crews and hospitality staff. The matters do not stay in their lanes.
Victory Tax Lawyers is admitted in California, 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 referral. The same attorneys handle the whole engagement.
Geography matters. The Robertson Boulevard office is about six and a half hours south of Napa on Interstate 5 / Highway 101. Most engagements run by phone, secure document portal, and email, with Form 2848 federal PoA and FTB Form 3520 PIT so every IRS or FTB notice routes to counsel. In-person meetings happen by appointment when that is what a client prefers. Spanish-speaking client service is available; vineyard and hospitality client teams are accommodated through scheduled secure-portal review of harvest-season and tourism-season records.
The seven steps of a VTL tax-resolution engagement
Free consultation
A 30-minute call with an attorney to outline the facts, the IRS or FTB notices received, and realistic resolution options.
Engagement letter
A written attorney-client agreement defines scope, fee, and authority. California-bar privilege and federal common-law attorney-client privilege both attach.
Federal & state PoA
Form 2848 filed with the IRS, FTB Form 3520 PIT or BE, CDTFA Form 392, or EDD DE 48 filed with the relevant California agency. All notices route to counsel — including for clients in unincorporated areas like Oakville, Rutherford, Angwin, Pope Valley, and Chiles Valley.
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.
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. For winery clients, we model IRC §263A method posture, IRC §1033 replacement-period elections, and IRC §1301 income averaging as part of the path.
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.
Compliance close-out
Post-resolution monitoring: quarterly estimates, return filings, and protection against IA default on either side. The case closes 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, Innocent Spouse claims, continuous absence from the United States for six months or more, and FEMA-declared disaster postponements under IRC §7508A.
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.
For a Napa County taxpayer who moved to Nevada or Texas thinking the California debt expires with the move — it does not. A federal balance assessed in 2016 may be approaching CSED expiration in 2026, while the FTB equivalent remains collectible until 2036. Submitting a federal OIC restarts part of 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.
Napa County venue: where matters are heard
Federal tax matters affecting Napa County taxpayers proceed in federal venues, most of which sit in San Francisco at the Phillip Burton Federal Building. State matters at the FTB, CDTFA, and EDD that reach formal appeal proceed through the California Office of Tax Appeals, with hearing locations in Sacramento (closest), Los Angeles, and Fresno. County-administered property tax and valuation matters happen in the City of Napa.
U.S. Tax Court — San Francisco trial sessions
The United States Tax Court holds Bay Area trial sessions at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco. Napa County petitioners designate San Francisco as the preferred place of trial under Tax Court Rule 140. From the City of Napa, the trip is roughly an hour south on Highway 29 / Interstate 80. Most cases settle before trial through IRS Office of Chief Counsel negotiations.
IRS Taxpayer Assistance Center — Napa
The IRS operates a TAC for Napa County at 1041 Jefferson Street, Suite 1, Napa, CA 94559. Appointments through apps.irs.gov/app/office-locator or 844-545-5640. TAC services include payment processing, transcript pickup, and identity-verification appointments. For controversy work, counsel-led communication with Revenue Officers and Settlement Officers is the better channel than walking into the TAC.
Napa County Superior Court
Napa County Superior Court is at the Historic Courthouse, 825 Brown Street, Napa, CA 94559. The Court hears divorce-related tax-allocation disputes, probate-tax priority (relevant on multigenerational winery transitions and Section 2032A special-use valuation), property-tax assessment appeals on writ review, and state-tax collection litigation. Civil tax-related actions route to the Historic Courthouse on Brown Street.
Napa County Treasurer-Tax Collector
The Napa County Treasurer-Tax Collector at 1195 Third Street, Suite 108, Napa, CA 94559 collects secured and unsecured property taxes under Cal. Rev. & Tax. Code Division 1. Property-tax disputes that touch federal-tax matters — a Prop 19 transfer triggering a federal gift-tax issue, an NFTL crossing a delinquent secured roll on vineyard ground — coordinate here.
Napa County Assessor
The Napa County Assessor at 1127 First Street, Room E, Napa, CA 94559 handles property valuation under Prop 13, Prop 8, and Prop 19 — including the Williamson Act agricultural-preserve contracts that apply to large portions of the county's working vineyards and rangeland under the Napa County Agricultural Preserve, the first such designation in California. Federal NFTLs and FTB State Tax Liens against Napa County parcels are recorded with the Assessor-Recorder-County Clerk. Assessment-appeal filings to the Assessment Appeals Board route through the Clerk of the Board.
U.S. District Court — Northern District of California
Napa County sits in the U.S. District Court for the Northern District of California, San Francisco Division. The San Francisco courthouse is at the Phillip Burton Federal Building, 450 Golden Gate Avenue, San Francisco, CA 94102. Federal refund suits under IRC §7422, federal-tax-lien priority disputes, and criminal-tax cases involving Napa County defendants proceed here. Appellate review goes to the Ninth Circuit.
California Office of Tax Appeals — Sacramento
The California Office of Tax Appeals hears appeals from FTB, CDTFA, and EDD determinations. Three-judge panels of Administrative Law Judges. Napa County appellants generally select Sacramento as the closest of the three OTA hearing sites, alongside Los Angeles and Fresno — the Sacramento panel sits roughly an hour and a half east of the City of Napa. Decisions are precedential and published.
