Property-tax appeal deadlines, explained by the states that set them

Published 2026-11-09 · FairAppealPacket

Every property-tax appeal starts the same way: a notice in the mail and a clock already running. The deadline is printed on the notice or runs from it, and in most jurisdictions there is no late filing — miss it and you wait a full year.

The windows we have sourced

Florida gives owners 25 days from the TRIM notice. Georgia allows 45 days from the notice date. Texas protests are due May 15 or 30 days after the notice, whichever is later. New Jersey's standard date is April 1; Pennsylvania's is September 1; Ohio allows until March 31 of the following year; Michigan commercial petitions are due May 31. Most deadlines cluster between February and September, with outliers on both ends — which is why a portfolio owner has a filing season in most months, not one annual crunch.

The trap inside the process

Most jurisdictions offer an informal review with the assessor's staff first, and many challenges resolve there. But as process guides state plainly: pursuing an informal review does not extend your formal appeal deadline. Owners lose their rights every year by waiting on a friendly phone call while the formal clock runs out.

What to do this week

Find your notice. Note the deadline. Then decide whether to appeal with your eyes open: what evidence you have, what a win is worth (reduction × your tax rate, repeated until reassessment), and — in Georgia, Pennsylvania and Washington — the disclosed risk that an appeal can raise your value. Our free check applies your numbers to your state's sourced rule. The full table lives on our deadlines page.
