Sign Up Before May 15Texas Property Tax Protest Deadline 2026
The deadline to protest your Texas property taxes is May 15, 2026. If your appraisal notice arrives late, you have 30 days from the date it was mailed, whichever is later.
May 15, 2026
This is the last day to file a protest with your county appraisal district. If you receive your Notice of Appraised Value after April 15, you have 30 days from the mailing date instead.
If your Notice of Appraised Value is mailed after April 15, your deadline is 30 days from the mailing date rather than May 15. Check the date printed on your notice. Most Texas homeowners receive their notices in April, which means May 15 applies in most cases.
If You Miss the Deadline
Missing the protest deadline means you forfeit your right to contest your property's assessed value for the entire 2026 tax year. There are no late filings, no appeals processes, and no exceptions granted by appraisal districts. Your only recourse is to wait until 2027.
