2025 and 2026 Penalty and Interest Chart

The Comptroller’s Property Tax Assistance Division provides the penalty and interest (P&I) chart below for use in calculating the total amount due on delinquent property tax bills based on the P&I rates established by Tax Code Section 33.01. The chart applies to delinquent tax payments in the months of October 2025 through September 2026.

To use this chart, find the month in which the tax is being paid. Go to the tax year in the column for which the delinquent tax was assessed. Then, multiply the corresponding P&I percentage amount by the tax amount to determine the amount of P&I on the delinquent base tax.

This chart does not apply to taxes that are under a deferral or abatement agreement. Penalty and interest on delinquent taxes that accrued prior to the deferral or abatement do not continue to accrue. Deferred or abated taxes have an interest rate of 5 percent annually.
