Texas Tax Code - TAX § 156.153. Reimbursement for Tax Collection

The person required to file a report under this chapter may deduct and withhold from the taxes otherwise due to the state on the monthly or quarterly return, as reimbursement for the cost of collecting the tax, one percent of the amount of the tax due as shown on the report.  If taxes due under this chapter are not paid to the state within the time required or if the person required to file a report fails to file the report when due, the person forfeits the claim to reimbursement that could have been taken if the tax had been paid or the report filed when due.
