State-Specific Property Tax Appeal Filing Timeline
Builds a personalized, backward-planned calendar that takes a homeowner from the day they receive their assessment notice all the way to their appeal hearing. The homeowner supplies their state, county, the date their assessment notice was mailed or received, and today's date. Working backward from the state's filing deadline rule, the tool lays out dated milestones in order: notice received, the evidence-gathering window (pulling comparable sales and checking the county's record for errors), the date to file the appeal by, the informal review or settlement opportunity, the point at which to request and review the appraisal district's evidence, hearing preparation, and the formal hearing itself. Because deadline mechanics differ sharply by state - a rolling number of days after the notice in Texas, Florida, and Georgia; a fixed calendar date in California, New Jersey, and on New York's Grievance Day; rolling township board sessions in Illinois; and a prior-year filing in Pennsylvania - the timeline is computed from the correct rule for the homeowner's state rather than a generic template. It tells the homeowner how many days remain and whether they still have time to file.
Example
Input: State: Texas; county: Harris County; notice mailed/received: April 8, 2026; today: April 12, 2026.
Output: Here is your Texas protest timeline, built backward from the filing deadline. Your deadline: Texas lets you file your Notice of Protest until May 15, OR 30 days after the appraisal district delivers your notice, whichever is LATER (Tex. Tax Code Sec. 41.44). Your notice was delivered April 8, 2026; 30 days from then is May 8, 2026, which is earlier than May 15 - so your deadline is May 15, 2026. As of today (April 12, 2026) you have 33 days. You have time. Your timeline: - April 8, 2026 - Notice received. (done) - Now through about May 8, 2026 - Evidence-gathering window. Pull recent comparable sales near your home, check your Harris Central Appraisal District record for factual errors (square footage, bed/bath count, lot size, condition), and write down your own opinion of value. This is the longest stretch - use it. - By May 15, 2026 - File your protest. The standard form is the Property Owner's Notice of Protest (Form 50-132); Harris County also accepts protests through its online iFile system. File before the deadline; confirm the exact method on the appraisal district's official page. - After filing, before your hearing - Informal review. Harris County offers an informal conference (and an online settlement option) where many protests are resolved without a formal hearing. Take it - bring your comps and your opinion of value. - At least 14 days before your ARB hearing - Request the district's evidence. Texas gives you the right to request copies of the information the appraisal district will use at your hearing at least 14 days beforehand (Tex. Tax Code Sec. 41.461). Request it as soon as your hearing is scheduled, then review it against your own evidence. - The few days before the hearing - Preparation. Organize your comparable sales, a one-page requested-value sheet, and a short opening statement. - Summer 2026 (date set by the board) - Formal hearing before the Appraisal Review Board (ARB). Harris County ARB hearings typically run from late spring through summer; the ARB will mail you a scheduling notice with your exact date and time - watch for it. Verify every date and the correct form on the Harris Central Appraisal District's official page before you rely on this.
