Do Missouri sales tax exemption certificates expire?

Yes. Missouri exemption certificates are typically valid for five years, unless otherwise noted on the certificate. This is true for exemption forms used for resale or other qualifying tax-exempt purchases. After expiration, a new exemption certificate must be issued to suppliers to maintain compliance.

It is necessary to audit certificates on a regular basis. If your business experiences structural transformations, such as a new entity of ownership, a tax identification number change, or a business purpose modification, the exemption certificate needs to be revised with immediate effect. Not renewing an expired certificate can lead to your suppliers charging you sales tax or even fines at the time of audit.

These renewals can be time-consuming to administer, especially for those businesses operating in multiple jurisdictions. That's why most of the businesses opt for professional assistance to maintain compliance.
