Quick Start for:

October is tax bill mailing month in the property tax calendar and kicks off 1999 property tax collections. With recent legislative changes, property tax collectors are asking questions about sending late and corrected tax bills. The Texas Property Tax Code addresses 27 different "types" of property tax bills. These bills may vary by delinquency date and in applying delinquent penalty and interest charges. The chart that begins below details each type of bill, its delinquency date, any penalty, and interest amount. The chart reflects recent legislative changes, including the application of the attorney's fees for delinquent taxes.

All property tax bills are due on receipt. Section 31.01, Property Tax Code, provides that failure to send or receive the tax bill does not affect the validity of the tax, penalty, or interest, the due date, the existence of a tax lien, or any procedure instituted to collect a tax.

The only exception is that a property tax collector may provide for not sending a bill under the total unpaid taxes for all taxing units the collector serves is $15 or more. A property owner also may file a written request with the collector that a tax bill not be sent until the total amount of unpaid taxes on the property is $15 or more.

For questions about property tax bills and collections, call the Property Tax Division's technical assistance hotline at 1-800-252-9121. In Austin, call 305-9999.
