Filing Late Property Tax Protests – Commercial/Residential Properties

Posted on:

04/29/2026

Missing the initial protest filing deadline does not always mean you are stuck with an excessive tax bill. In some cases, corrective action is still possible.

Filing a Late Protest: Section 25.25

Under Texas Tax Code Section 25.25, property owners may request certain corrections after the regular protest deadline.
Key points include:

  • Extended filing window: You may file a late correction request until January 31 of the following year.
  • Penalty consideration: If successful under certain provisions, a 10% penalty will apply to the corrected tax amount.
  • Value thresholds:
    • For non-homestead properties, the protested market value must exceed the final market value by at least one-third.
    • For homestead properties, the threshold is 25% over market value.
  • Clerical errors: You may also correct clerical mistakes, duplicate listings, or incorrect ownership information.
  • Notice issues: If you did not receive required notice, additional remedies may apply under Section 41.411.

Note: Property taxes must still be paid by January 31 to avoid delinquency and additional interest. The undisputed amount of property tax must be timely paid by the January 31 deadline to preserve late-file rights.
