(a) If a person who has filed a security under this subchapter fails to pay the taxes imposed by this chapter or by a city under the Local Sales and Use Tax Act or fails to file a tax return required by this chapter or under the Local Sales and Use Tax Act, the comptroller shall issue a deficiency or jeopardy determination containing a demand for the amount of taxes, penalties, and interest due. The determination shall state that if payment is not made on or before the last day that the deficiency may be paid without incurring further penalty, the security or a part of the security may be forfeited.(b) If the security filed by the person is a surety bond, the comptroller shall send a copy of the determination to each surety on the bond and shall demand payment from both the person filing the bond and each surety. A surety's obligation under the bond is not affected by whether the surety has a record of the receipt of a copy of the comptroller's determination notice or payment demand.
