Yes. California state gives you clear, formal paths to challenge Franchise Tax Board findings. Most income tax audits end with a Notice of Proposed Assessment. You generally have 60 days from the notice date to file a written protest. If you pay the proposed amount within 15 days of the Notice of Proposed Assessment date, FTB stops interest on that amount as of the notice date; if you pay later, interest stops as of the payment date while you continue your protest. If the FTB later issues a Notice of Action that you still disagree with, you have 30 days to appeal to the independent Office of Tax Appeals. These timelines are strict, so read every notice carefully and act before the dates shown.
Understand the Notice You Received and the Immediate Deadlines
A Notice of Proposed Assessment explains the proposed changes, penalties, and interest. It is not a bill unless you take no action by the “protest by” date. File a protest within 60 days to keep the matter in the administrative review track. Interest keeps running during the protest. To halt further interest, you may pay the proposed amount within 15 days of the notice and still continue your protest. If the FTB affirms some or all of the adjustments after a protest, it will issue a Notice of Action. At that point, you can file an appeal with the Office of Tax Appeals within 30 days of the Notice of Action date.
How to Build a Strong Protest and What a Review Looks Like
A protest should identify each disputed issue, state the facts, apply California state law, and attach organized support that ties back to your filed return. The FTB Protest Unit assigns a hearing officer who may request documents and hold an informal conference. For residency and sourcing, expect to provide domicile indicators, travel and work location records, and employer documentation. For pass-through owners, be ready with partnership or S corporation workpapers that connect apportionment and basis to your return. If the FTB sustains any part of the assessment, the Notice of Action will tell you what remains in dispute and start the 30-day appeal window at the Office of Tax Appeals. The OTA is independent of the FTB, can hold a hearing or decide on the papers, and applies California statutes and precedent to the record you present.
Missed the Protest Window or Seeking a Refund Instead
If you miss the 60-day protest deadline and the assessment becomes final, you can still pay and file a refund claim. For most individuals, a refund claim is timely if filed within the later of 4 years from the original due date of the return or 1 year from the date of the overpayment. If the IRS later changes your federal taxable income, different timing rules apply for related claims. If your claim is denied or six months pass without action, you can appeal to the OTA or file a refund suit in the superior court within the applicable time limits.
Interest, Penalties, and Settlement or Closing Agreement Options
Interest accrues from the original return due date and compounds daily at the state’s published rate, so running the numbers and paying strategically can reduce carry cost. California state offers a One-Time Penalty Abatement for eligible timeliness penalties if you meet the criteria, and separate reasonable cause relief may be available. For disputed cases, the FTB operates a Settlement Program that resolves protested or appealed matters based on hazards of litigation. The program is different from an Offer in Compromise, which turns on the ability to pay. The FTB also uses closing agreements to resolve specified issues conclusively. These resolution tools can be considered during a protest or appeal where appropriate.
Practical Steps that Improve Outcomes
File a California power of attorney so your representative can communicate directly with the auditor and Protest Unit. Rebuild the schedules an auditor will prepare, reconcile books and bank data to returns, and align California state entries with any federal tax changes. If you are disputing residency or sourcing, assemble contemporaneous proof before you file protest. If you need more time to gather documents, file a timely protest to preserve rights, and then work out a submission schedule with the reviewer. Keep current compliance clean while you contest past years; new delinquencies only complicate the file.
