Tax Attorney in Antioch, California

The United States Tax Court holds Northern California trial sessions at the Phillip Burton Federal Building and U.S. Courthouse, 450 Golden Gate Avenue, San Francisco CA 94102 — about 50 miles west of Antioch through the Caldecott Tunnel and across the Bay Bridge, or via the eBART line out of the Antioch Station at Hillcrest Avenue plus BART transfer at Pittsburg/Bay Point. An Antioch petitioner designates 'San Francisco, California' as the place of trial on the petition under Tax Court Rule 140. Sacramento is the secondary California venue and is sometimes the better calendar choice for East Contra Costa petitioners depending on docket timing — Sacramento sits 60 miles northeast of Antioch up Highway 4 and I-5. The petition itself is filed with the Tax Court in Washington, D.C., or through the court's DAWSON electronic filing system. The 90-day deadline under IRC §6213(a) is jurisdictional and the court cannot extend it.

The closest IRS TAC is at the Ronald V. Dellums Federal Building, 1301 Clay Street, Suite 160S, Oakland CA 94612 — 45 miles west of Antioch via Highway 4 and I-580. Appointments are scheduled by calling 844-545-5640 or through apps.irs.gov/app/office-locator. For most resolution work, in-person TAC visits are not required — we represent Antioch clients by Form 2848 Power of Attorney and route IRS notices directly to counsel. Walk-in service at the TAC handles ITIN W-7 certification, account inquiries, payment processing, and Form 911 Taxpayer Advocate Service requests. Sacramento TAC at 4330 Watt Avenue and San Francisco TAC at 450 Golden Gate Avenue are alternatives if the Oakland calendar is full.

Kaiser Permanente Antioch Medical Center at 4501 Sand Creek Road operates with roughly 427 physicians across 52 specialties. Locum tenens, per-diem, and contract physicians paid 1099-NEC frequently see annual compensation between $300,000 and $500,000. Three rate-stacks drive the burden: federal income tax at the top brackets, self-employment tax under IRC §1401 at 15.3 percent on the first $168,600 of net earnings (2024 wage base, indexed) and 2.9 percent thereafter plus the 0.9 percent Additional Medicare on wages over $200,000 single or $250,000 joint, and California income tax topping at 13.3 percent under R&TC §17041. Quarterly Form 1040-ES estimates fix the federal side; FTB Form 540-ES fixes the California side. An S-corp election under IRC §1362 (Form 2553) can split income into reasonable compensation plus distribution where the practice supports it, lowering SE-tax exposure — subject to reasonable-compensation scrutiny under Watson v. Commissioner. Solo 401(k) and SEP-IRA contributions under IRC §401 and §408(k) reduce taxable income further.

A commercial fisher running out of the Antioch Marina at 5 Marina Plaza files Schedule C with the standard self-employment lines plus several fishing-specific items. Boat depreciation runs under IRC §168(k) bonus depreciation (phasing — 60 percent for 2024, 40 percent for 2025, 20 percent for 2026) or IRC §179 expensing where the §179 cap fits. Major boat repairs and engine replacements are capitalized under §263 then recovered through depreciation, with the §263A UNICAP rules excluded for small taxpayers under the §448(c) gross-receipts test. The federal fuel-tax credit under IRC §6427(l) for off-highway diesel is the largest line many Delta fishers miss — diesel used in a commercial fishing vessel qualifies for the per-gallon refund on Form 4136. The IRC §38 general business credit picks up several adjacent items. CDTFA fuel-tax administration handles the California side through Part 31 of the Revenue & Taxation Code. SE tax under §1401 runs against the net before the §199A qualified-business-income deduction, subject to the W-2 wage and UBIA tests. Striped bass, sturgeon, and Chinook seasonal-closure income volatility usually justifies a Partial Pay IA under §6159 rather than a streamlined plan when balances accumulate.

Newer Antioch subdivisions in the Sand Creek Focus Area — Vineyards at Sand Creek, The Ranch, and other approved tracts of the originally 8,950-home plan reduced to roughly 4,000 homes — sit inside a Community Facilities District established under Streets & Highways Code §53311 (the Mello-Roos Community Facilities Act of 1982). The CFD special tax funds the streets, parks, schools, and infrastructure that the city did not bond directly through the general property tax. Annual CFD assessments on Antioch newer subdivisions commonly run $1,200 to $3,500 per parcel, layered on top of the underlying 1 percent Prop 13 ad valorem rate under Cal. Const. Art. XIIIA §1, supplemental assessments on change of ownership, and county direct charges. The CFD line is not deductible as a property-tax itemized deduction under IRC §164 unless it qualifies as an assessment for general public welfare rather than a benefit to a specific parcel — most Mello-Roos charges fail that test under Treasury Regulation §1.164-4. Sellers must disclose CFD obligations under Cal. Civ. Code §1102.6b at the time of resale. A property-tax reduction petition on the underlying ad valorem amount goes to the Contra Costa County Assessment Appeals Board at 1025 Escobar Street, Martinez, by the September 15 or November 30 filing window depending on the assessment type.

Marathon Petroleum acquired the Martinez refinery from Andeavor (formerly Tesoro) on October 1, 2018, and the facility has gone through several ownership names — Tosco Avon, Phillips Avon, Golden Eagle, Tesoro, Andeavor, Marathon. Marathon announced the Martinez shutdown / renewable-fuels conversion in 2020, displacing the bulk of the 740-person refinery workforce, many of whom live in Antioch, Pittsburg, Bay Point, Oakley, and Brentwood. The defined-benefit plan distribution at separation is reported on Form 1099-R and taxed as ordinary income under IRC §72 with after-tax basis recovery under the simplified method or general rule. A lump-sum eligible rollover distribution can be rolled to an IRA under IRC §402(c) within 60 days to defer the federal income tax — the 20 percent mandatory withholding under §3405(c) applies if the distribution is paid to the participant rather than direct-rolled. Pre-age-59½ withdrawals trigger the 10 percent additional tax under IRC §72(t) unless an exception applies — the §72(t)(2)(A)(v) separation-from-service-at-55 exception is the most common refinery-worker fix, and the §72(t)(2)(A)(iv) substantially-equal-periodic-payment series under Rev. Rul. 2002-62 is the secondary route. Net Unrealized Appreciation treatment under §402(e)(4) preserves long-term capital-gain treatment on employer-stock distributions in-kind. California conforms to the federal treatment with limited exceptions and adds the state income-tax layer at up to 13.3 percent.

PG&E gas-distribution and gas-transmission employees represented by IBEW Local 1245 working out of the East Bay operations centers commonly hold defined-benefit pension accruals under the PG&E Retirement Plan, employer stock under the PG&E Corporation Long-Term Incentive Plan, and post-bankruptcy settlement allocations from the 2019 Chapter 11 reorganization. Three federal-side issues recur for Antioch residents: (1) the §415(b) annual benefit limit on the defined-benefit accrual for higher-earning supervisors; (2) the §83(b) election window on restricted-stock grants — 30 days from grant under Treasury Reg. §1.83-2(c); and (3) tax treatment of the Camp Fire and other wildfire settlement allocations — most are excluded from gross income under IRC §139 as qualified disaster-relief payments where the recipient meets the §139(b) and (c) tests, but case-by-case review is required. The California layer applies through R&TC §17041 conformity. Union dues are no longer deductible as a federal miscellaneous itemized deduction after the 2017 TCJA suspension under §67(g), but the California return still allows union-dues deduction on Schedule CA under R&TC §17240.

Sutter Delta Medical Center at 3901 Lone Tree Way is a 145-bed Level II Trauma Center and the only not-for-profit hospital serving East Contra Costa County. Traveling nurses on 13-week contracts at Sutter Delta typically receive a split compensation package: a taxable hourly wage on W-2, plus per-diem stipends for housing, meals, and incidentals that are excluded from gross income under IRC §162 and §274 only if the assignment is genuinely 'away from home' as defined in Rev. Rul. 93-86 and the §911 tax-home rules. The §162 tax-home rule treats a regular place of business as the tax home — for a traveler with no fixed regular place of business, the IRS examines the taxpayer's regular place of abode in a real and substantial sense under Rev. Rul. 73-529. A traveler whose 'permanent tax home' is a parent's address with no actual rent or utility responsibility loses tax-home status — the per-diems become wages subject to FICA and federal income tax. The one-year rule under §162(a)(2) terminates the away-from-home status if the assignment is realistically expected to last more than one year. The IRS Travel Nurse compliance campaign opened in 2021 and remains active. We file CP2000 responses, audit-defense memoranda, and amended returns where the documentation supports the position.

Amazon East Bay facility-codes for delivery stations and sortation centers include sites in Tracy, Stockton, Oakland, San Leandro, and Hayward that draw Antioch and East County workers along the Highway 4 corridor. Amazon W-2 compensation typically includes Restricted Stock Units (AMZN RSUs) and Employee Stock Purchase Plan shares under IRC §423. RSUs are taxed as ordinary wage income at vest at the share's fair market value, and Amazon as the federal employer withholds at the 22 percent supplemental rate under IRC §3402(g). For Antioch residents in California's top brackets that undershoots the combined federal-plus-state ceiling — the 13.3 percent California addition under R&TC §17041 alone bridges the gap. Senior operations managers, software engineers, and AGM-track operators in the top brackets routinely owe an additional 15 to 20 percent in April. ESPP shares purchased at the §423 discount carry an ordinary-income component on disposition equal to the lesser of the discount or the actual gain, plus capital gain or loss on top. The qualified-disposition rules require holding two years from grant and one year from purchase to preserve favorable capital-gain treatment on the spread. Underwithholding usually rolls into a multi-year Installment Agreement under IRC §6159.

Antioch is a frequent origin point for California out-migration to lower-tax states. Cal. R&TC §17014 defines a California resident as anyone in the state other than for a temporary or transitory purpose, plus any person domiciled in California who is outside the state for a temporary or transitory purpose. The Office of Tax Appeals applies the nine-factor closer-connection test from Appeal of Stephen Bragg (2003-SBE-002) — physical presence, real-property holdings, vehicle registration, driver's-license state, voter registration, professional and business filings, banking relationships, family ties, and the locations where children attend school. Appeal of Bindley (2018-OTA-179P) layered on sourcing-of-services analysis. The cleanest record for an Antioch departure to Houston, Austin, Las Vegas, Henderson, Phoenix, Scottsdale, or Boise is: (1) sell or genuinely rent the Antioch home at arm's length; (2) re-title vehicles and surrender the California driver's license within 10 days of establishing residency in the new state under that state's rule (Texas 30 days, Nevada 30 days, Arizona 30 days, Idaho 90 days); (3) re-register to vote in the new state and cancel California voter registration; (4) move primary banking and brokerage accounts; (5) keep California physical presence under 45 days per year — 183 days is the safe-harbor outer limit but the FTB scrutinizes returns claiming non-residency at much lower day counts. The FTB has four years from filing under R&TC §19057 to open the audit and significantly longer if no return was filed. We build the closer-connection file before the move whenever possible, and we defend the audit when it lands.

90 days from the date stamped on the Notice of Deficiency (NOD or '90-day letter') to file a petition with the U.S. Tax Court under IRC §6213(a) — 150 days if the notice is addressed to a person outside the United States. The deadline is jurisdictional and the Tax Court cannot extend it. An Antioch petitioner designates 'San Francisco, California' as the place of trial. Filing the petition stops the IRS from assessing or collecting on the deficiency until the case resolves under §6213(a). Missing the 90 days forfeits prepayment review; you then either pay the deficiency and sue for refund in U.S. District Court (Northern District of California, Oakland Division) or the U.S. Court of Federal Claims under 28 USC §1346(a)(1), or wait for collection action and assert other defenses through a Collection Due Process hearing under IRC §6320 or §6330. The cleanest path is to file the Tax Court petition timely. The DAWSON electronic filing system at dawson.ustaxcourt.gov is the standard mechanism.

60 days from the date on the Notice of Proposed Assessment to file a protest under Cal. R&TC §19041. The protest goes to the FTB and triggers a Protest Hearing Officer review. If the FTB issues a Notice of Action against you, an OTA petition follows within 30 days under R&TC §19045. The OTA is an independent tribunal that replaced the Board of Equalization on tax appeals in 2018; Antioch petitioners draw either the Sacramento OTA hearing room at 400 R Street or the San Francisco OTA hearing room at 455 Golden Gate Avenue depending on calendaring. Missing the 60-day NPA protest window converts the proposed assessment into a final assessment and the FTB moves to collection. The fix at that stage narrows to a refund claim under R&TC §19306 after payment or a compromise under §19443 based on collectibility. Both protest and OTA windows can be extended only by mutual written consent of the FTB and the taxpayer.

The Trust Fund Recovery Penalty under IRC §6672 is the IRS mechanism to reach individuals personally for unpaid employment-tax withholdings the business failed to remit. The penalty equals 100 percent of the federal income-tax withholding plus the employee share of FICA — the 'trust fund' portion of Form 941. A Revenue Officer conducts a Form 4180 interview to identify 'responsible persons' (anyone with check-signing authority, ability to determine which creditors get paid, or operational control over payroll) and to establish 'willfulness' (knowing failure to pay over while paying other creditors). The TFRP is jointly and severally assessable against every responsible person. Common targets in Antioch are restaurant owners on Somersville Road and along East 18th Street, warehouse and 3PL operators along Wilbur Avenue and the Highway 4 corridor, owner-operator trucking LLCs running aggregates and fill out of the Delta region, and construction subcontractors. The criminal companion at IRC §7202 reaches willful failures to collect or pay over. EDD asserts a parallel state TFRP under Cal. Unemp. Ins. Code §1735.

For non-filers, the IRS generally accepts six years of back returns under IRM 1.2.1.6.18 as the compliance bar. The FTB looks back four years by default under R&TC §19057, longer for non-filed or fraud years. The sequence is: (1) pull IRS Account Transcripts and Wage-and-Income Transcripts across all open years to confirm what the IRS already knows; (2) pull FTB MyFTB records to confirm what the FTB has; (3) prepare and file the six federal years and at least the four California years; (4) once compliance is current, request a Collection Information Statement-based resolution (Installment Agreement, Currently Not Collectible status, or Offer in Compromise) sized to the facts. Filing the missing returns first is what unlocks every relief option. Refunds older than the §6511 three-year window (two years from payment if later) are forfeited. The §7201 felony exposure for willful failure to file rises with the count of unfiled years and the dollar size of the implied liability. The IRS Substitute for Return under §6020(b) is what the IRS prepares when you do not — usually disadvantageous and worth replacing with a filed return.

IRC §6502(a) gives the IRS 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 Offer in Compromise (OIC pendency plus 30 days), bankruptcy (stay plus six months), Collection Due Process hearings, Innocent Spouse claims, and continuous absence from the United States for six months or more. Cal. R&TC §19255 gives the FTB twenty years — double the federal tail. CDTFA collection runs ten years under R&TC §6711 with similar tolling. EDD operates under its own collection window in the Unemployment Insurance Code. A federal Antioch 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 Installment Agreement 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.
