Do I need to periodically renew resale and exemption certificates I've collected from customers, and do I need my customers to show me a copy of their Texas sales tax permit?

Plain-English summary

A retailer asked the Comptroller about the mechanics of handling Texas resale and exemption certificates from customers — specifically, whether these certificates need to be periodically renewed, and what documentation the retailer should keep.

The Comptroller's answer was short and practical: there is no requirement to renew either a resale certificate or an exemption certificate once collected. That said, it's good practice to periodically check with the customer that the certificate's information — address, phone number, and similar details — is still accurate. Separately, there's no requirement that a customer provide the retailer a copy of their Texas sales tax permit as backup documentation. Rule 3.285 ("Resale Certificates; Sales for Resale") and Rule 3.287 ("Exemption Certificates") govern the certificates themselves, and sample certificate forms were provided to the retailer for reference.

What this means for you

Retailers accepting resale or exemption certificates from customers

Once you have a valid certificate on file from a customer, you don't need to make them fill out a new one periodically — just spot-check that their contact information hasn't changed. You also don't need to demand a copy of their sales tax permit as part of your certificate file.

Businesses providing resale or exemption certificates to their vendors

You're not required to resubmit your certificate on any schedule, though your vendor may reasonably ask you to confirm your details are still current from time to time.

Accountants and tax professionals advising on certificate recordkeeping practices

This letter simplifies what's often assumed to be a periodic-renewal compliance burden — Rule 3.285/3.287 don't require it. The practical audit-readiness advice is simply keeping the original certificate and verifying customer information stays current, not chasing renewals.

Common questions

Q: Do resale certificates need to be renewed periodically?
A: No — there's no renewal requirement, though it's wise to verify the customer's information on file is still accurate.

Q: Do exemption certificates need to be renewed?
A: No, same answer as resale certificates.

Q: Do I need to collect a copy of my customer's Texas sales tax permit along with their resale certificate?
A: No — there's no such requirement.

Q: Can I rely on this letter for my own certificate recordkeeping practices?
A: No. This opinion is based on the facts presented, and additional or different facts may yield different results; it can be relied on only by the taxpayer it was issued to.

Original ruling text

January 25, 2000

Dear **:

Thank you for your recent letter regarding Texas sales tax resale and exemption
certificates.

I have enclosed a copy of Rule 3.285 "Resale Certificates; Sales for Resale"
and Rule 3.287 "Exemption Certificates" for your review. I also enclosed a copy
of a Texas Resale Certificate and a Texas Exemption Certificate.

There is no requirement to renew exemption or resale certificates. It is wise,
however, to verify with your customer that the information (address, phone
number, etc.) on the certificate is still correct.

Additionally, there is no requirement that a taxpayer provide a copy of his or
her Texas sales tax permit to his/her supplier.

This opinion is based on the facts presented. Additional or different facts may
yield different results.

You may call me toll free 1-800-531-5441, extension 5-9787, if you have any
questions or need more information. The direct line is 512/305-9787. You may
also write to Tax Policy Division, Comptroller of Public Accounts.

Sincerely,

Philip Knisely
Tax Policy Division
