Can You Appeal Property Taxes for Previous Years? Multi-Year Appeal Guide
TL;DR
Some states allow retroactive property tax appeals for prior years, but most do not. Where allowed, you typically have to prove the assessment was wrong in the prior year using data available at that time. States like New York, New Jersey, and some others permit multi-year corrections. Check your state's rules before assuming you can recover past overpayments. Even if retroactive appeals are not available, filing now will save you money going forward.
States That Allow Prior-Year Appeals
Most states limit appeals to the current assessment year. However, some allow retroactive corrections:
- New York: SCAR and certiorari proceedings can cover prior tax years in some circumstances
- New Jersey: Tax Court appeals can address multiple years
- Michigan: Tax Tribunal can review prior years in specific situations
- Ohio: Board of Revision complaints can sometimes cover prior periods
- Pennsylvania: Some counties allow retroactive corrections for factual errors
When Retroactive Appeals Succeed
The strongest cases for prior-year appeals involve:
- Data errors. Wrong square footage, incorrect features, or other factual mistakes that inflated the assessment for multiple years
- Clerical errors. The assessor applied the wrong tax rate or classification
- Missed exemptions. You qualified for an exemption but did not apply. Some states allow retroactive exemption claims.
How to File a Multi-Year Appeal
- Check your state's statute for retroactive appeal rights
- Determine the lookback period (how far back you can go)
- Gather evidence that applied during each year you are appealing
- File with the appropriate body (often a state-level tribunal, not the local board)
- Consider professional representation for multi-year claims, as they tend to be more complex
Even If You Cannot Go Back, Act Now
If your state does not allow retroactive appeals, every day you wait costs money. Filing now stops the overpayment from continuing. A successful appeal this year saves you money every year going forward until the next reassessment.
