Where to find your deadline

Start with your assessment notice. Then confirm the date on the official assessor, appraisal district, board of review, tax commission, or county website. If the notice and website conflict, call the local office.

Why deadlines vary

Some places start the clock when notices are mailed. Others start after assessment rolls are published. Some use fixed annual dates, while others use a number of days after notice.

What to prepare before the window opens

Even if your local filing window is not open yet, you can review your record, gather comps, check exemptions, and decide whether the assessment is worth challenging.
