Beginning Jan. 1, 2012, a person claiming an exemption from motor vehicle sales tax and limited sales tax on the purchase of certain items used in the production of agricultural and timber products will be required to have a Texas Agriculture and Timber Exemption Registration Number (Ag/Timber Number). This will not be their social security number. Farmers can apply for their 11 digit farm registration number at www.getreadytexas.com.
