What the Form Is For
Texas Form 00-985, Assignment of Right to Refund, is an official document issued by the Texas Comptroller of Public Accounts that transfers the right to claim a sales tax refund from the seller who collected the tax to the purchaser who paid it. Think of it as a "permission slip" that allows you, the buyer, to go directly to the state for your refund instead of relying on the seller to handle it.
This form becomes necessary when you've paid sales or use tax in error but you're not the business that actually sent that tax money to the Texas Comptroller's office. The seller collected the tax from you and remitted it to the state, so technically the seller holds the right to request any refund. Form 00-985 formally transfers that right from the seller (called the "assignor") to you, the purchaser (called the "assignee").
The form is most commonly needed when purchasers don't hold a Texas sales and use tax permit at the time of purchase, or when sellers prefer not to process refunds themselves. Once properly completed and signed by both parties, this assignment gives you the legal authority to file a refund claim directly with the Comptroller's office without further involvement from the seller.
When You’d Use Form 00-985
Common Situations
You'll typically need Form 00-985 in several specific situations. The most common scenario occurs when you're a purchaser without a sales tax permit who paid tax on an item that should have been exempt or tax-free. For example, if you bought equipment that qualifies for manufacturing exemptions but were incorrectly charged sales tax, you'd first ask the seller for a refund. If the seller refuses to process the refund or prefers you handle it directly, they must complete Form 00-985 to assign their refund rights to you.
Amended Claims or Past Errors
Another situation arises when filing an amended claim or correcting past purchases. Perhaps you discovered months or years later that multiple purchases were taxed incorrectly. Rather than asking the seller to amend their own returns, the seller can provide you with Form 00-985 for each vendor, allowing you to consolidate all your refund claims in one submission to the Comptroller's office.
Industry-Specific Use
The form is also used by crude oil and natural gas producers for invoices dated before September 1, 2021. While newer legislation allows these severance taxpayers to claim direct refunds without Form 00-985, transactions before that effective date still require the traditional assignment process.
Statute of Limitations Reminder
Importantly, you must obtain and submit Form 00-985 within the four-year statute of limitations period. The clock starts from the date the tax was originally due and payable to the state, not from when you paid the seller. If you wait too long to request the assignment from your seller, you may lose your right to any refund entirely.
Key Rules or Details for 2022
Four-Year Statute of Limitations
The four-year statute of limitations is the most critical rule governing Form 00-985. A valid assignment must reach the Comptroller's office before this deadline expires. The four years run from the date the tax was due and payable to Texas, which is typically when the seller filed the return that included your transaction. Missing this deadline means you forfeit your right to the refund permanently.
One Form Per Vendor
Each vendor requires a separate Form 00-985. If you paid tax in error to five different sellers, you must obtain five separate assignment forms—one signed by each seller.
Required Signatures and Details
Both the assignor (seller) and assignee (purchaser) must sign the form with authorized personnel. The form must include detailed information about the tax payment being assigned, including:
- Specific period
- Transaction details
- Exact refund amount
Must Be Submitted With Claim
Form 00-985 must accompany your refund claim. You’ll still need to complete Form 00-957 or use the online system and attach supporting documentation.
Tolling the Statute
The statute of limitations stops running only when your complete refund claim package arrives with all required elements.

FAQs
What’s the difference between the assignor and assignee on Form 00-985?
The assignor is the seller who collected and remitted the tax. The assignee is the purchaser who paid the tax. The form transfers the refund rights from the seller to the buyer.
Can I use one Form 00-985 for multiple sellers?
No. Each seller requires a separate form to ensure proper documentation of assigned refunds.
What if the seller refuses to sign Form 00-985?
They are not required to assign the right. You may need to pursue other legal options if they refuse both refund and assignment.
How do I calculate the four-year deadline?
Count four years from when the tax was due to the state—not the purchase date.
What if I submit Form 00-985 without a claim?
Nothing happens. The assignment alone does not trigger a refund—you must submit a full claim.
Can I submit Form 00-985 electronically?
Yes. The Comptroller accepts electronic submissions and signatures via email or online systems.
Do I need Form 00-985 if I had a sales tax permit?
Not always. Permit holders may use alternative refund methods, but non-permit holders must use this form.
