You're over-assessed when the County's value is higher than what your home would actually sell for — and then you're over-paying every year until you appeal. Ohio complaints against valuation are filed with the County Board of Revision by March 31 for the prior tax year, per Ohio Rev. Code §5715.19. Ohio reappraises on a 6-year cycle with a 3-year update.
Honest null: Cuyahoga County's assessment roll isn't onboarded into our live check yet, so we can't pull your specific over-assessment here. Compare your assessed value to recent nearby sales on the county assessor portal — if it's higher than what your home would sell for, you're over-assessed and should appeal by the deadline above.
Most owners who win use a contingency property-tax appeal firm — it costs nothing unless they cut your bill, then takes a share of the first-year saving. About 95% of over-assessed owners never appeal, so the saving is usually left on the table.
