Can I appeal property taxes for prior years?
Usually you can only appeal the current year's value through the normal appeal, but most states have a separate correction process that can fix certain prior-year errors — in Texas, for example, a §25.25(c) motion can correct qualifying errors going back up to five years.
The normal appeal deadline applies to the current year's assessment — once it passes, you generally cannot re-litigate the value for that year. But "appealing prior years" really means two different things, and one of them is often still available.
Current-year value appeal: time-limited. Every state sets an annual deadline to challenge that year's value (a fixed date, or a window after the notice is mailed). Miss it and the value for that year is typically final, subject only to limited late-filing or "good cause" exceptions in some states.
Prior-year correction: a separate, longer-window remedy. Most states have a correction-of-error process for objective mistakes — wrong square footage, a property that doesn't exist, double assessment, or a clerical error — that reaches back further than the appeal deadline. These fix factual errors, not differences of opinion about market value.
- Texas is the clearest example: under Tex. Tax Code §25.25(c), the appraisal review board can correct the appraisal roll for the five preceding years to fix clerical errors, multiple appraisals, inclusion of property that does not exist, or an error in who owned the property on January 1.
- California allows correction of clerical/mechanical errors not involving a value judgment within four years under Rev. & Tax. Code §4831.
What you usually cannot recover: a simple over-valuation for a closed prior year where you just disagree with the market value the assessor used. Correction statutes target errors of fact, not unappealed opinions of value.
Action steps: if you missed a deadline but believe the record contains a factual error, ask your assessor or appraisal district about the prior-year correction process and the form it requires (Texas uses a motion to the ARB under §25.25). If it's purely a value disagreement, focus on filing on time for the current and future years.
State-by-State Variations
| State | Exception or Variation |
|---|---|
| Texas | Texas allows a motion under [Tex. Tax Code §25.25(c)](https://statutes.capitol.texas.gov/Docs/TX/htm/TX.25.htm) to correct clerical errors, multiple appraisals, inclusion of nonexistent property, or an ownership error for any of the five preceding years; a §25.25(d) motion can address a value that exceeds the correct value by more than one-fourth (homestead) for the current year if filed before taxes go delinquent. |
| California | California permits correction of clerical or mechanical errors not involving the assessor's value judgment within four years under [Rev. & Tax. Code §4831](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=4831.&lawCode=RTC). |
