Tex. Loc. Gov't Code § 130.008
If the comptroller or the Texas Department of Motor Vehicles determines that the county tax assessor-collector has accepted payment for fees and taxes to be remitted to that department in violation of Section 130.004 or that more than two percent of the fees and taxes to be received from the assessor-collector are not remitted because of the acceptance of checks that are not honored by the drawee bank or of credit card invoices that are not honored by the credit card issuer, the department may notify the assessor-collector that the assessor-collector may not accept a check or credit card invoice for the payment of any fee or tax to be remitted to that department. A county tax assessor-collector who accepts a check or credit card invoice for the payment of a fee or tax, after notice that the assessor-collector may not receive a check or credit card invoice for the payment of fees or taxes to be remitted to a department, is liable to the state for the amount of the check or credit card invoice accepted.
