Many Texas property owners focus on the Texas property tax protest deadline May 15. However, the deadline may also be 30 days after delivery of the notice of appraised value, whichever is later. Do not rely only on a generic date without checking your 2026 notice.
January 1 is the valuation date for many Texas property tax purposes. Appraisal districts generally determine what the property was worth as of this date for the tax year.
Property tax bills from the prior year are often due by the end of January. If taxes remain unpaid, delinquency, penalty, and interest issues may follow. Owners concerned about payment penalties can also review our Texas property tax penalty calculator guide.
Taxes imposed for the previous year generally become delinquent on February 1 if the bill was mailed on time. This deadline is separate from the protest deadline for the current year’s appraisal notice.
Appraisal notices for residence homestead properties are commonly mailed in the spring. Once you receive a notice, review the market value, exemption details, property characteristics, and filing deadline immediately.
April 15 is an important rendition deadline for many property types, including business personal property. The deadline may be extended in certain situations if a proper request is made.
April 30 is commonly associated with many exemption application deadlines. Exemption timing can affect taxable value, so owners should confirm requirements with their appraisal district. For more guidance, visit our Texas property tax exemptions article.
Appraisal notices for properties other than single-family residence homesteads, including commercial real estate, are often mailed in the spring. Commercial owners should begin reviewing value, income data, and comparable sales as soon as the notice arrives.
May 15 is commonly the Texas property tax protest deadline. In many cases, this is the last day to file a protest with the appraisal district or Appraisal Review Board process. The deadline may instead be 30 days after the notice of appraised value is delivered, whichever is later.
If you are asking when the property tax protest deadline is in Texas, the safest next step is to review the current notice and file before the listed deadline. For a full protest overview, visit our Texas Property Tax Protest page.
This is the critical filing window for most owners who want to challenge an appraised value. Filing on time preserves your right to protest; evidence preparation and hearing strategy may continue after filing.
After filing, many owners may participate in informal review or an Appraisal Review Board hearing. Learn more in our Appraisal Review Board hearing guide.
Prior-year delinquent taxes may begin to incur larger penalties. This is separate from the current-year appraisal protest process.
Appraisal Review Board approval of appraisal records often happens during the summer, with timing depending on county size and procedure. If your protest result remains unfair, appeal options may need to be evaluated quickly.
Appeal deadlines can differ from the initial protest deadline. If the protest result does not resolve the issue, visit our Property Tax Appeal Texas page to understand next-step options.

Not always. May 15 is the commonly referenced deadline, but if your notice is delivered later, the deadline may be 30 days after delivery of the notice. Some situations may involve different timing.
