When is the property tax appeal deadline in my state?
Deadlines vary by state and follow one of four patterns: a fixed calendar date, a rolling window after your notice mails, sequential board sessions, or a prior-year filing — so the only reliable answer is your own assessment notice.
Property tax appeal deadlines are set by state law and fall into four patterns. The single most reliable source is your own notice of value, which prints your jurisdiction's exact deadline.
1. Fixed calendar dates. A specific date each year, regardless of when notices mail: Nevada around Jan 15, Massachusetts Feb 2 (an abatement application, and taxes must be current), Ohio Mar 31 (a complaint against valuation, strictly enforced), New Jersey Apr 1, Los Angeles County, CA Nov 30.
2. Rolling deadlines. A set number of days after your notice is mailed, often with an "or" clause. Texas is May 15 or 30 days after the appraisal district mails the notice, whichever is later, per the Texas Comptroller. Florida is 25 days after the TRIM notice; Washington is 60 days from notice or July 1, whichever is later, under RCW 84.48.010.
3. Board-session windows. Sequential township or county windows rather than one date: Cook County, IL opens township by township; Michigan uses the March Board of Review; Wisconsin requires a 48-hour intent-to-file before the Board of Review.
4. Prior-year filing. A few states file the year before the tax year — Pennsylvania counties typically around Aug 1 of the prior year; New Jersey added/omitted assessments by Dec 1.
Two universal rules. First, the head term differs by state — Texas "protest," New York "grievance," Florida/Arizona "petition," Massachusetts/New Hampshire/Maine "abatement," Ohio "complaint," Wisconsin/Colorado "objection," and "appeal" everywhere else — so search using your state's term. Second, deadlines are rarely extended; if you miss it, your remedy is usually a correction-of-error filing or trying again next year.
Always confirm the current-year date on your state tax authority or county appraisal/assessor site, because legislatures adjust these dates and a single weekend or holiday shift can move the effective deadline.
