It’s time to renew your Ag/Timber number! 

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.

Persons claiming the agricultural exemption on their purchases already give their supplier an exemption certificate that includes the Ag/Timber Number.

Effective Jan. 1, 2016, the exemption certificate must also include a current expiration date.

Ag/Timber Number holders need to renew their Ag/Timber number before Jan. 1, 2016 in order to get a current expiration date.

We will send “how to renew” letters directly to persons already registered with us, and we are in the process of updating our website with this information. Renewal starts in October, and phone, online and mail renewal options will be available
