California FTB Penalty Waiver: Form 2917 and One-Time Abatement

The California Franchise Tax Board will waive a late-filing or late-payment penalty in two situations: you show reasonable cause for missing the deadline, or you qualify for the one-time abatement under Revenue and Taxation Code Section 19132.5. Individuals and fiduciaries request a California FTB penalty waiver on Form FTB 2917; business entities use Form FTB 2924. The concept is simple, but the FTB denies requests that lack specific documentation, skip the pay-first rule, or miss the refund-claim window, so the details decide the outcome.

Which Penalty You’re Trying to Remove

Two penalties can be waived through this process: the late-filing (delinquency) penalty and the late-payment penalty. Both statutes contain the same escape valve, which is that the penalty does not apply if the failure was “due to reasonable cause and not due to willful neglect.”¹

Interest is a different animal. A successful penalty waiver removes the penalty charges from your account, but interest on the underlying tax keeps running, including during the months the FTB is reviewing your request. Interest can only be abated in narrow circumstances, and it uses a different form. More on that below.

Reasonable Cause: What the FTB Accepts

Reasonable cause means you exercised ordinary business care and prudence but still couldn’t file or pay on time because something outside your control got in the way. The FTB’s internal audit procedures spell out what reviewers treat as acceptable and what they reject.

Reasons that generally work:

Death or serious illness of the taxpayer, a responsible officer, or the person who handled the filing, where no one else could step in.
Destruction of records by a fire, flood, or other unforeseeable event that eliminated the documents needed to prepare the return.
Presence in a governor-declared disaster zone, where the taxpayer filed within the extended relief period.

Reasons that almost never work: confusion about filing due dates, the belief that a return wasn’t required because the business was inactive or operated at a loss, failure to receive forms after an address change, and lack of funds to pay the tax.² That last one trips people up. The FTB treats “I couldn’t afford to pay” as separate from “I couldn’t comply despite trying.” If you had the information needed to file but simply didn’t have the money, the filing penalty may be abatable while the payment penalty typically is not.

When Your Tax Preparer Missed the Deadline

Hiring an accountant who drops the ball does not automatically give you reasonable cause. You can delegate the technical work of preparing a return, but you cannot delegate the basic responsibility to file on time and pay what you owe. If your preparer missed the date, the FTB will ask whether you supplied the necessary information, checked on the status before the due date, and chose someone competent in the first place. Reasonable reliance on professional advice can support a waiver for a substantive tax position, but it rarely excuses a missed filing date.

The One-Time Abatement Under Section 19132.5

Revenue and Taxation Code Section 19132.5 sidesteps the reasonable-cause analysis entirely. If you’ve maintained a clean record with California, you can request a one-time waiver of a timeliness penalty, meaning either the late-filing or late-payment penalty, for a single tax year. You don’t need to explain why you were late.³

All three of these must be true when you request it:

You’ve never been granted this one-time abatement before, and you either had no prior California personal income tax filing requirement or have never had an unabated timeliness penalty. A penalty that was later removed for reasonable cause does not count against you.
Every California personal income tax return you were required to file has been filed.
All tax, penalties, fees, and interest on those returns are paid in full or covered by a current installment agreement, aside from the penalty you’re asking to have removed.

The request can be made orally or in writing.³ This option applies only to individual taxpayers and only to taxable years beginning on or after January 1, 2022. Because it’s genuinely once per lifetime, most tax professionals suggest saving it for a year with a sizable penalty rather than burning it on a small one.

How to File Form FTB 2917 or 2924

Individuals and fiduciaries use Form FTB 2917, “Reasonable Cause – Individual and Fiduciary Claim for Refund.” Business entities use Form FTB 2924, “Reasonable Cause – Business Entity Claim for Refund.”⁴ Both are on the FTB website. The forms work the same way; the account they link to is the main difference.

A few ground rules before you fill anything out. Prepare a separate form for each tax year. The FTB will not act on your claim until the balance for that tax year is paid in full, which means you typically pay the penalty first and then request a refund of it.⁵ If you’re filing on someone else’s behalf, submit a Power of Attorney (Form FTB 3520 PIT for individuals) separately.

Writing Part 3: The Reasonable Cause Explanation

Part 3 is where most requests succeed or fail. The FTB wants a factual narrative tied to specific dates, not a general plea for mercy. Describe what happened, when it started, when it ended, and why it prevented you from filing or paying despite your best efforts. For a medical emergency, include the dates of hospitalization or incapacity. For destroyed records, describe what was lost and why replacements couldn’t be obtained in time.

Attach third-party documentation that corroborates your timeline: medical records, hospital discharge summaries, death certificates, police reports, insurance claims, FEMA correspondence. Order the documents to match the chronology in your explanation so the reviewer can follow the story without hunting through loose pages.

Don’t Miss the Refund Statute of Limitations

Your claim must be filed within the refund statute, which is the latest of three dates: four years after the original return due date, four years after the date you timely filed the return, or one year from the date of overpayment.⁴ Miss the window and the FTB cannot issue a refund no matter how strong your reasonable cause is.

Where to Send It

By mail:

Franchise Tax Board
PO Box 942840
Sacramento, CA 94240-0040⁵

You can also log in to your MyFTB account and upload the form with a message explaining the request.⁶ The online route gives you confirmation of receipt, which matters when a deadline is close.

What Happens After You File

There is no guaranteed processing time. The FTB will mail a letter approving or denying the claim. If six months pass with no response, the claim is automatically deemed denied, a detail that’s easy to miss because silence feels like the agency is still working on it.⁶

The FTB does not handle appeals internally. If your claim is denied, or deemed denied after six months, you can appeal to the Office of Tax Appeals or file suit in superior court.⁶ For most taxpayers, the OTA is the practical route. You have 90 days from the date the FTB mails its denial notice to file. If your claim was deemed denied with no written response, you can appeal at any time, but once the FTB actually issues a written denial, the 90-day clock starts.⁷ Appeals can be filed through the OTA Portal, by mail, or by fax. Include a copy of the denial notice and all supporting documentation, even if you already sent it to the FTB.⁸

Interest Abatement Is a Separate Request

If you believe the FTB’s own processing delay caused interest to pile up, that’s handled on Form FTB 3701, not FTB 2917 or 2924. The FTB can only abate interest when it resulted from an unreasonable error or delay by an FTB or IRS employee performing a ministerial or managerial act, or when a governor-declared state of emergency or federal major disaster declaration caused the delay. Ordinary delays on your end, including the same illnesses and disasters that support penalty relief, do not qualify for interest relief. Interest keeps accruing until the balance is paid in full.⁹
