How often properties are reassessed is a local rule: some counties rewrite value every year, others wait two to six years. There is no national cadence.
How often properties are reassessed varies by state: some write a new value every year, and others wait two to six years between full reappraisal cycles. There is no single national cadence. IAAO names that interval a reappraisal cycle, set by local law, not by a nationwide clock.
Do all counties reassess property every year?
No. The IAAO glossary defines a reappraisal cycle as the time taken or permitted to reappraise a class of property. Ohio's Department of Taxation describes a six-year full reappraisal plus a third-year update in between. Other places rewrite the roll every year. This page does not invent a U.S. average.
Example: one county mails a new number every January. Another waits six years for a full pass, with a midpoint update. Those two calendars are illustrations of the range, not a schedule for a named street.

What is a reappraisal cycle for property taxes?
A reappraisal cycle is the local interval between full mass revaluations of the roll. Annual counties catch market swings faster. Multi-year counties can carry an older printed value for longer. A property tax appeal, when one is filed, is aimed at the number on this cycle's notice. The property tax glossary and the mass appraisal page stay on what that group run is. FairAppeal monitors your assessment every year, not just once. The Fair Appeal review carries no upfront cost.
