Property taxes
Behind on property taxes, sued by the county, or facing a sheriff’s or constable’s sale? Find the paper you got, see the dates and the money, and write to the right office yourself.

Penalty & interest calculator
Type the unpaid tax and the day you would pay. The penalty (6% the first month, up to 12% on July 1), interest (1% a month) and the collection penalty are computed exactly as Tax Code § 33.01 and § 33.07 describe — with the month-by-month cost of waiting.

Unpaid tax Taxes for 2025 are delinquent if not paid before 2026-02-01. Tex. Tax Code § 31.02(a) | $2,500.00 |
Penalty12% The penalty is 6% for the first month, plus 1% for each additional month or part of a month before July 1. From July 1 it is 12%, and it does not go higher. Tex. Tax Code § 33.01(a) | $300.00 |
Interest8% Interest is 1% for each month or part of a month the tax stays unpaid. It has no cap and keeps running even after a court judgment. Tex. Tax Code § 33.01(c) | $200.00 |
Collection penalty (attorney fee)20% If the taxing unit hired a delinquent-tax attorney, it may add a penalty of up to 20% of the tax, penalty and interest. It was incurred on 2026-07-01. This uses 20%; your tax office may use a different rate or recompute it as interest grows. Tex. Tax Code § 33.07(a) | $600.00 |
