California FTB Notice Final Request for Federal Information – Pending Claim for Refund (FTB 1526Q)

The FTB 1526Q is a final request notice from the Franchise Tax Board asking you to provide federal tax information to support a pending refund claim you’ve filed with California. It’s a last-chance letter—the FTB has already asked for this information at least once, and you haven’t responded or your response was insufficient. If you don’t reply, the FTB will deny your refund claim and close the case.

California frequently requires federal information to verify state refund claims because California income tax is tied so closely to federal adjusted gross income. If you filed an amended California return claiming a refund—based on a federal audit change, an amended federal return, or a corrected income figure—the FTB wants to see the corresponding IRS documentation. Common documents requested include IRS audit reports, Form 4549 (Income Tax Examination Changes), or a copy of the amended federal return and proof the IRS accepted it.

The Reed Corporation helps clients respond to FTB 1526Q notices with properly organized, complete documentation packages. We know exactly which IRS documents the FTB needs and how to present them so the FTB reviewer can match everything up quickly. A complete first response avoids additional delays and gets your refund processed faster.

If you don’t respond to the FTB 1526Q within the timeframe stated on the notice—typically 30 days from the notice date—the FTB will deny your pending refund claim. You won’t get the money you’re owed, and the FTB will close the file. To reopen a denied refund claim, you’d need to file a new claim, which starts the clock on California’s refund statute of limitations over again and extends the entire process by months.

California Revenue and Taxation Code Section 19306 generally limits refund claims to the later of four years from the original return due date or one year from the date of overpayment. If your refund claim is based on a federal adjustment, Section 19311 gives you two years from the date the IRS assessment or refund becomes final to file with California. Missing the FTB 1526Q deadline doesn’t toll those periods—you could lose your refund permanently.

The Reed Corporation treats FTB 1526Q notices as urgent. We immediately gather the required federal documentation, prepare a cover letter identifying each document’s relevance to the California refund claim, and submit everything by certified mail with return receipt. Deadline tracking is critical, and we make sure nothing slips through.

The specific documents vary based on the reason for your refund claim. If your California refund flows from a federal audit that reduced your taxable income, the FTB needs the IRS Revenue Agent Report (Form 4549), the closing agreement or consent form (Form 870 or 906), and the IRS tax account transcript showing the assessment change. If the refund stems from an amended federal return, the FTB needs a copy of Form 1040-X and proof the IRS accepted and processed it—usually an IRS account transcript showing a refund or balance reduction.

California’s conformity to federal income rules under Revenue and Taxation Code Section 17024.5 means that many federal adjustments automatically affect your California tax. But California doesn’t process those changes automatically—you have to file a protective claim or amended California return within the applicable window and then provide the federal backup when asked. The FTB 1526Q is the FTB’s way of saying the backup documentation is missing.

The Reed Corporation often prepares California conformity packages when clients undergo IRS audits. We get ahead of the FTB 1526Q by submitting a complete California protective claim at the same time as the federal audit closes, with all supporting documentation attached. That eliminates the back-and-forth and typically speeds up the California refund significantly.

After you respond to the FTB 1526Q with complete documentation, the FTB typically takes 6 to 12 weeks to review your submission and issue a refund determination. Processing times vary based on claim complexity and FTB workload. If the FTB approves the refund, you’ll receive a Notice of Proposed Refund giving you 30 days to respond before the refund is issued. If they deny it, you’ll get a Notice of Action explaining the denial.

Interest on a delayed refund is a silver lining. California Revenue and Taxation Code Section 19340 requires the FTB to pay interest on refunds not issued within 45 days of the original claim—or within 45 days of when you filed the complete response to the 1526Q. The current rate is tied to federal rates under IRC Section 6621, which has been around 7% to 8% for 2023-2024 returns.

The Reed Corporation monitors FTB refund timelines for clients and follows up when processing runs long. We know when to call the FTB practitioner priority line versus when to wait for the standard process to run. If your refund is being held up by something beyond the 1526Q documentation, we’ll identify it and address it directly.

Yes. California isn’t bound by IRS refund determinations. California has its own conformity rules, its own adjustments to federal AGI, and its own audit process. The FTB can agree with your federal position and still deny a California refund for reasons specific to state law—like a California add-back item you didn’t account for, or a difference in how California treats a particular deduction. Getting a federal refund is evidence that your federal income was overstated, but it doesn’t automatically transfer to California.

One specific area of non-conformity that trips people up: California doesn’t conform to the federal exclusion for qualified opportunity zone investments under IRC Section 1400Z-2, California doesn’t follow the federal SALT deduction cap the same way, and California has its own rules on net operating loss carrybacks that differ from federal. If your federal refund is based on a provision California doesn’t follow, the FTB can legitimately deny the state refund even after approving the federal piece.

The Reed Corporation reviews both the federal and California tax positions side by side when preparing conformity-based refund claims. We identify California non-conformity items before filing and disclose them properly so the FTB has a complete picture. That upfront transparency tends to result in faster, cleaner refund processing with fewer information requests like the 1526Q.
