Ag/Timber Numbers and Exemption Certificates

Texas law requires a person claiming an exemption from sales tax on the purchase of certain items used to produce agricultural and timber products for sale to hold an Agricultural and Timber Exemption Registration Number (Ag/Timber Number). The law also requires the Ag/Timber Number to be renewed every four years on a uniform date, regardless of the date the number was first issued.  The next renewal deadline will be December 31, 2023.

For more information, please visit the Texas Comptroller’s website at or contact their office by calling 1-800-252-5555.  You may print the application form or apply online by visiting                                                                 

BCEC encourages Ag/Timber Number holders to verify that their Ag/Timber numberare up to date and have a current expiration date.  Members who are exempt are responsible for furnishing BCEC their Ag/Timer information.  Tax exemptions will apply only to BCEC members who submit their updated Ag/Timber verification.
