Texas Sales and Use Tax Frequently Asked Questions

A prepayment discount is a discount of 1.25 percent that monthly or quarterly taxpayers can take in addition to the 0.5 percent timely filing discount allowed any taxpayer filing timely reports and payments.

A monthly or quarterly filing taxpayer can take a prepayment discount if the taxpayer does each of the following:

• prepays a “reasonable estimate” of their state and local sales and use tax liability for the entire reporting period
• files a prepayment report (PDF) if paying by mail
• files their monthly or quarterly report showing the total tax amount due on or before the reporting period’s due date, and pays the balance of the tax due for the period

The prepayment report and tax prepayment for a monthly filer are due on or before the 15th day of each month. For example, for a January return that’s due on Feb. 20, the prepayment report and tax prepayment are due on Jan. 15.

The prepayment report and tax prepayment for a quarterly filer are due on or before the 15th day of the second month of each quarter. For example, for the first quarter return filing period that is due on April 20, the prepayment report and tax prepayment are due on Feb. 15. See the Prepayment Discount Examples.
