Bexar County Property Tax Timeline: Key Dates for 2025

Property tax season in Bexar County can be overwhelming—especially if you’re unfamiliar with the deadlines and steps involved. Understanding the 2025 property tax calendar can help you stay on track and avoid missing crucial windows to take action. Whether you're a first-time homeowner or a seasoned property owner, this guide breaks down every important date and what you need to do.

Why the Timeline Matters

When it comes to protesting property taxes, timing is everything. From receiving your appraisal notice to preparing evidence, scheduling meetings, and attending hearings, every step is tied to a specific deadline. Missing one can cost you the opportunity to reduce your property tax bill for the year.

Key 2025 Property Tax Dates for Bexar County

January 1: Appraisal Date

This is the date used by the Bexar Appraisal District (BCAD) to determine your property’s market value. Any evidence you use to protest must reflect the condition and market trends as of this date.

April: Appraisal Notices Mailed

BCAD typically mails out appraisal notices in early to mid-April. These notices detail your property’s new assessed value and instructions for filing a protest.

What to do: Review your notice as soon as it arrives. Compare the new value to previous years and check for errors in property details.

May 15 (or 30 Days After Notice): Protest Deadline

This is your last chance to file a protest. The official deadline is either May 15 or 30 days after your notice was mailed—whichever is later.

What to do: File your protest online, by mail, or in person. Don’t wait until the last minute in case of technical issues.

June–July: Informal Reviews and ARB Hearings Begin

Once protests are submitted, BCAD will schedule informal review meetings. If your case isn’t resolved informally, you’ll proceed to a formal hearing before the Appraisal Review Board (ARB).

What to do: Gather strong evidence (comps, photos, estimates) and organize your argument. Ballard Property Tax Protest can handle this for you to ensure your case is airtight.

October: Tax Rates Finalized

Local taxing entities, like school districts and cities, finalize their tax rates in October. This is the final step in determining your total tax bill.

Note: You cannot protest the tax rate, only the value set by BCAD.

November: Tax Bills Issued

Tax bills are mailed out once the rates are set. Even if you’re still appealing your valuation, you must be prepared to pay your taxes by the due date.

January 31, 2026: Tax Payment Deadline

This is the final date to pay your 2025 property taxes without penalties or interest. After this date, late fees and collections may apply.
