How property tax assessments work
How your county turns market value into a tax bill: the valuation date, the assessment ratio, caps and exemptions, and where an appeal fits.
How assessments work and how to appeal one, written by Appealmetrics Research from statutes, state revenue departments and county assessors. Each guide lists its sources.
How your county turns market value into a tax bill: the valuation date, the assessment ratio, caps and exemptions, and where an appeal fits.
The three figures to find on an assessment notice, what each state calls its market value, the property facts to check, and where the appeal deadline is printed.
A market-value appeal says your home would sell for less than its assessment; an unequal-appraisal appeal says it is assessed higher than comparable homes. Which one your state recognizes decides the evidence.
How homestead caps limit yearly increases in taxable value, the caps in each state, and why a value appeal only saves money when it lands below the capped figure.
What happens at an informal review with the assessor, what happens at a formal board hearing, and where you can go after the board.
What appeal boards accept: recent comparable sales, comparable assessments where uniformity counts, factual errors and condition problems. And what they ignore.
The deadline rule for a first-level property tax appeal in every state and DC, from 25 days after the notice to fixed dates like May 15, March 31 and June 30.
The assessment ratio is assessed value divided by market value. What it is in each state, how ratio studies measure it, and how to use it to check your assessment.
Skip the appeal when the value is fair, the saving is small, a cap already holds your taxable value below market, or the board could raise your value.
After you file: acknowledgement, an informal offer, the hearing, the written decision, the next level’s deadline, and how a reduction reaches your bill.
