California Franchise Tax Board Representation: Audits, Assessments, and Appeals

The Franchise Tax Board is California’s income and franchise tax agency. It is a state agency — not a federal one, and not a division of the IRS — and it operates under its own statutes, its own procedural deadlines, and its own appeals forum. Taxpayers who assume an FTB matter works like an IRS matter are frequently surprised, almost always unpleasantly.

The most consequential difference is time. The IRS generally has ten years to collect an assessed liability. Under California Revenue and Taxation Code section 19255, the FTB has twenty years — and that clock restarts when certain subsequent items, including collection cost recovery fees and lien fees, are assessed against the same year. A California liability can therefore remain enforceable long after its federal counterpart has expired.

At The Law Office of Pietro Canestrelli, we represent individuals and businesses in FTB audits, protests, appeals, and collection matters throughout Temecula, Murrieta, San Diego, Riverside, and San Bernardino, as well as for former residents now living outside California who remain under FTB scrutiny.

What the FTB Actually Administers

The FTB collects personal income tax, corporate franchise and income tax, and a range of related items. It is one of three California tax agencies a business may deal with simultaneously, and confusing them costs taxpayers real deadlines:

• FTB — income and franchise tax
• CDTFA — sales and use tax and special taxes
• EDD — payroll and employment tax, including worker classification

Each has a different notice, a different protest deadline, and in the EDD’s case a different appellate body altogether. A business under examination by more than one is running parallel clocks that do not pause for each other.

How FTB Matters Begin

Federal Adjustments That Flow to California

The most common path is derivative. When the IRS adjusts a federal return, Revenue and Taxation Code section 18622 requires the taxpayer to notify the FTB within six months. The notification deadline controls how long California then has to assess:

• Notified within six months — the FTB has two years from notification to assess
• Notified after six months — the FTB has four years
• Never notified — the FTB may assess at any time, with no expiration

That last line does most of the damage. A taxpayer who settles an IRS audit, pays the federal bill, and considers the matter closed has often left an open-ended California assessment window behind. We see these surface five and ten years later.

Residency and Sourcing Audits

California audits departure aggressively. According to FTB data, the agency completed 520 residency audits of out-of-state filers in 2023 — up 126% from 230 in 2019. There is no California exit tax; the 2026 billionaire tax measure is a proposed ballot initiative, not law. What exists instead is a factual inquiry into whether you ever stopped being a resident.

California presumes continued residency until domicile is affirmatively changed. FTB Publication 1031 applies a closest-connections analysis across roughly nineteen factors — where your home, family, vehicles, professional licenses, physicians, bank accounts, and social ties are located. A 546-day safe harbor exists for certain employment-related absences, and a rebuttable presumption applies to taxpayers present in California more than nine months of the year.

Selling a business, exercising options, or recognizing a large capital gain in the year of a move reliably draws a residency examination. So does keeping a California home.

Filing Enforcement and Nonfiler Cases

The FTB matches income data and issues a Demand for Tax Return when it believes a return is due. Ignoring it produces a Notice of Proposed Assessment computed from gross receipts with no deductions and no credits — nearly always far higher than the real liability. The remedy is to file, not to argue. Our page on unfiled returns covers the sequence.

The Notice of Proposed Assessment and the 60-Day Protest

An FTB examination concludes with a Notice of Proposed Assessment (NPA). You have 60 days to file a written protest. This is the single most important deadline in California income tax practice.

A timely protest keeps the assessment from becoming final, suspends collection, and moves the file to an FTB protest hearing officer, where the case can be developed with documents and legal argument. Miss it and the NPA becomes a final assessment. Your remaining options narrow to paying the tax and filing a refund claim — meaning you fund the dispute in full before you can litigate it.

The protest window rewards preparation. The strongest protests arrive with the documentary record already assembled: bank statements reconciled, substantiation organized by issue, and a legal position stated with citation. Protests written as a general objection to the result rarely move the number.

Appealing to the Office of Tax Appeals

If the protest is denied, the FTB issues a Notice of Action, and the appeal goes to the Office of Tax Appeals — generally within 30 days.

OTA was created by the Taxpayer Transparency and Fairness Act of 2017 to take tax appeals away from the elected Board of Equalization. Appeals are heard by panels of three Administrative Law Judges who are independent of the FTB, and OTA publishes precedential opinions that can be cited in later matters. It is a genuine forum, and it decides a meaningful share of cases for taxpayers — particularly residency and substantiation disputes where the record is well built.

It also rewards work done earlier. OTA reviews the record developed at protest. A thin protest produces a thin appeal.

FTB Collections

Once an assessment is final and unpaid, the FTB’s collection powers are broad and, in several respects, faster than the IRS’s:

• Bank levies — issued without the layered federal notice sequence
• Earnings Withholding Orders for Taxes — wage garnishment served directly on the employer
• State tax liens — recorded at the county level, reaching California real property
• License suspension — professional and occupational licenses for taxpayers on the top delinquency list
• Interception — refunds, lottery winnings, and other state payments

Available resolutions include installment agreements, hardship or currently-not-collectible status, penalty abatement for reasonable cause, and an offer in compromise on Form FTB 4905 PIT for individuals or 4905 BE for entities. Because of the twenty-year statute, California’s collection-potential math differs sharply from the IRS’s, and an offer accepted federally is evaluated independently by the FTB — acceptance in one does not carry to the other. Our liens, levies, and garnishments and tax relief pages address the collection side in more depth.

Where California Diverges from Federal Law

California is a fixed-date conformity state. Senate Bill 711, signed in October 2025, moved the conformity date to January 1, 2025 — before the One Big Beautiful Bill Act was signed in July 2025. California therefore does not conform to OBBBA, and the gaps are substantial:

• Bonus depreciation — never adopted, and OBBBA’s permanent 100% restoration does not apply
• Section 179 — capped at $25,000 with a $200,000 phaseout, against $2.5 million federally
• Qualified business income — no California equivalent of the Section 199A deduction
• Research expensing — California did not adopt OBBBA’s Section 174A relief
• Tips and overtime — the new federal deductions do not reduce California taxable income

Every one of these produces a Schedule CA adjustment. Returns that carry federal figures onto the California return without the add-back create visible discrepancies, and discrepancies generate assessments.

On the favorable side, the pass-through entity elective tax was extended through 2030 by Senate Bill 132. The entity pays 9.3% and the owner takes a credit. For 2026 and later years, missing the June 15 prepayment no longer voids the election, but it reduces the owner’s credit by 12.5% of the shortfall. For pass-through owners in S corporations and LLCs, this is often the largest single planning item on the return.

Frequently Asked Questions

How long does the FTB have to collect a tax debt?

Twenty years from the date the latest liability for the year becomes due and payable, under R&TC 19255. The clock can restart when a later item — a collection cost recovery fee, lien fee, or installment agreement fee — is assessed for that year, and it is suspended during bankruptcy and certain payment plans.

What is the deadline to protest a Notice of Proposed Assessment?

60 days from the date on the notice. A timely protest suspends collection and preserves your right to contest without paying first. After 60 days, the assessment is final and the only route is pay-and-claim-refund.

Can the FTB audit me after I moved out of California?

Yes, and it does — residency audits of out-of-state filers more than doubled between 2019 and 2023. California presumes continued residency until domicile changes, and examines the year of departure closely when a large gain, business sale, or option exercise falls in it.

Does the FTB automatically follow the IRS?

No. The FTB frequently mirrors federal adjustments, but it assesses independently and conformity gaps mean California can reach income the federal return does not tax. An IRS settlement does not resolve the state liability.

What happens if I never told the FTB about a federal audit adjustment?

Under R&TC 18622 the assessment window never closes. There is no expiration for that year, which is why old federal adjustments surface as new California assessments years later.

Is the Office of Tax Appeals independent of the FTB?

Yes. OTA is a separate agency, and appeals are decided by three-judge panels of Administrative Law Judges who do not work for the FTB. Its precedential opinions are published and citable.

Speak With a California Tax Attorney

FTB matters turn on deadlines that do not forgive lateness — 60 days to protest, 30 days to appeal, six months to report a federal adjustment. If you have received a Notice of Proposed Assessment, a Demand for Tax Return, a residency questionnaire, or a collection notice, the useful moment to get advice is now, while the options are still open.
