The three deadlines seniors ask about most
| Deadline | Detail |
|---|---|
| Exemption application | April 30 (the Comptroller's own Exemptions page says "before May 1" and its 65+ FAQ page says "April 30" — we follow April 30 as the operative statutory deadline and flag the inconsistency) |
| Appraisal protest | May 15, or 30 days after the appraisal district mails the notice, whichever is later |
| Late exemption filing window | up to two years after the delinquency date |
For the exemption application process itself, see how to apply. For protest timing, see should you protest.
