File property tax protest by May 15 if value is too high. The window to protest an appraisal district valuation generally closes May 15 (or 30 days after the appraisal notice, whichever is later), and missing it locks in the year's tax bill.
Pay property taxes by January 31. Texas property taxes become delinquent February 1, after which penalties and interest accrue on the unpaid balance.
