Texas Sales Tax Refund: Deadline, Filing, and Appeals

If you overpaid sales tax in Texas, you can get it back by filing a Texas sales tax refund claim with the Comptroller of Public Accounts within four years of the date the tax was due and payable.¹ How you file depends on whether you hold a Texas sales and use tax permit. Permit holders file directly. Everyone else has to go through the seller first.

Who Files and How

If you hold a Texas sales and use tax permit, you file your own refund claim with the Comptroller using Form 00-957, the Texas Claim for Refund.² You already have a tax account with the state, so the claim goes straight to the agency that collected the money.

If you don’t hold a permit, the seller is the first stop. The vendor can refund the tax to you directly, or the vendor can sign Form 00-985, the Assignment of Right to Refund, which transfers the vendor’s refund rights to you so you can file your own claim with the Comptroller.³ You need a separate Form 00-985 for each vendor you paid tax to in error, and every form has to be signed by the vendor’s authorized personnel. One exception: if you are asking only for a refund of local tax paid to a remote seller, the assignment form is not required.⁴

There is a practical trap here. If the vendor has gone out of business, getting a signed Form 00-985 is difficult or impossible, and the Comptroller does not publish a specific workaround. If that is your situation, call the Comptroller’s office before you assemble the rest of your claim package.

The Four-Year Deadline

Texas gives you four years from the date the tax was due and payable to file a claim. Miss that window and the statute treats it as a permanent waiver of your demand against the state.¹

One narrow exception. If the Comptroller issued a jeopardy or deficiency determination against you, you have six months after that determination becomes final to file a refund claim for amounts found due in the determination, even if the four-year window has already closed.¹ Texas Tax Code Section 111.1042 also allows a taxpayer and the Comptroller to agree in writing to extend the limitations period before it expires, though those agreements typically come out of audits rather than routine requests.

The clock matters. If you discover an overpayment pattern running five or six years back, you will only recover the last four.

What to Include With Your Claim

The core document is Form 00-957. It asks for your taxpayer identification number, the total refund amount, the type of tax, the period covered, and a written statement explaining each reason a refund is owed.⁴ That written statement carries more weight than most filers realize. A vague reason like “tax was charged in error” invites follow-up questions and stalls the review. Cite the specific exemption or legal basis for each category of transactions.

Alongside Form 00-957, you generally need:

Detailed invoices showing the tax paid on each transaction. If you have more than ten invoices, put them on the Comptroller’s schedule using Form 01-911.⁵
Form 01-911, which lists vendor name, vendor taxpayer number, invoice number and date, item description, an exemption code tied to the applicable rule, and a breakdown of state, city, county, and special district tax amounts. List invoices in date order grouped by vendor.⁵
Valid exemption certificates, if the claim rests on an exemption. Incomplete certificates will be disallowed regardless of when you obtained them.⁶
Form 00-985 for each vendor, if you did not remit the tax to the Comptroller yourself.²
Form 01-137, Limited Power of Attorney, if an accountant, attorney, or other representative files the claim on your behalf.²

Confirm the totals on Form 01-911 match the amount on Form 00-957. Mismatched totals and missing taxpayer ID numbers are the errors that bounce a claim before anyone reviews the substance.

How to Submit the Claim

You have three options. The most convenient is the online Texas Claim for Refund web form on the Comptroller’s website, which accepts supporting documents as PDF or ZIP files up to 2MB.² You can also download the fillable Form 00-957 PDF and email it with supporting documentation to refund.request@cpa.texas.gov. Or print everything and mail it to the Comptroller of Public Accounts, Attn: Sales and Motor Vehicle Tax Refunds, 111 E. 17th Street, Austin, TX 78774-0100.⁴

Whichever route you choose, check that scanned or uploaded documents are legible. Blurry invoice images are a common reason a claim stalls in review.

When the Audit Division Gets Involved

Larger claims get closer scrutiny. The Audit Division reviews a claim if it is for $25,000 or more in taxes, if the refund period overlaps with an ongoing or completed audit, or if your smaller claims over the past four years add up to $25,000 or more.⁷

Once assigned, an auditor will reconcile your sales and use tax accounts against what you reported, review invoices and exemption certificates, and research whether the claimed exemptions actually apply. The auditor may ask to see the purchased items in person to confirm how they are being used, and may use statistical sampling for claims that involve a large volume of transactions.⁷

Two things to watch. The auditor will set a deadline for producing requested documentation, usually about 30 days, and missing it can lead to the claim being denied in full or in part.⁷ The auditor may also discover tax underpayments during the reconciliation and issue an assessment against you on top of processing the refund. Make sure your overall reporting is clean before you file a large claim.

After verification, the auditor holds an exit conference to walk through the results. Approved refunds are paid by paper check mailed to the address on file unless you have provided special instructions.⁷ Any timely filing discount you took, outstanding penalties, or existing tax liabilities can reduce the final amount you receive.²

Interest on Approved Refunds

Texas pays interest on refunded amounts, at the lesser of the annual rate earned on deposits in the state treasury during November of the prior calendar year, or the rate set under Tax Code Section 111.060. Interest starts accruing on the later of 60 days after you paid the tax or the due date of the tax report, and runs until the Comptroller issues the refund.⁸

One exception matters: if you take a credit on your own tax return instead of filing a formal refund claim, that credit does not earn interest.⁸ On a large overpayment where the review takes months, the interest can be meaningful.

Appealing a Denied Claim

If the Comptroller denies your claim, you have 60 days from the date of the denial letter to request an administrative hearing. That deadline is firm. Miss it and you lose the right to a hearing, and you cannot later file a lawsuit to recover the refund.⁹

The request must be in writing and include a Statement of Grounds that explains the legal and factual basis for why the refund should be granted. A request that fails to state valid grounds will not be accepted. You can submit it by mail or hand-delivery to the Comptroller’s Audit Processing Section at 1801 Congress Avenue, Suite 14.300, Austin, Texas 78701-1320, by email to audit.processing@cpa.texas.gov, or by fax to (512) 463-2274.⁹

Extensions of the 60-day period are granted only for emergencies or extraordinary circumstances, and you have to request the extension before the original deadline expires. Late requests are not considered.⁹ Put that date on your calendar the day the denial letter arrives.

A Note on Federal Tax Treatment

Texas has no state income tax, so the federal question turns on whether you previously deducted state and local sales taxes on your federal return. If you itemized and claimed Texas sales taxes, you may need to include the refund amount in federal income for the year you receive it, though the $10,000 cap on state and local tax deductions means many itemizers could not deduct the full amount paid in the first place, which reduces or eliminates the taxable portion of the refund.¹⁰ If you took the standard deduction in the year you paid the tax, a sales tax refund is not taxable income. For a business, the refund typically reverses a previously deducted expense. If the refund is large enough for the federal treatment to matter, talk to a tax professional.
