Yuma County property tax appeal 2028: deadline, forms and how to file
To appeal a Yuma County assessment, file with the Yuma County Assessor's Office by mail or in person; in Arizona the deadline is 60 days after the Notice of Value is mailed. Confirm the exact date on your notice or with the assessor; we add each county's 2028 date here when it is published.
Notices of Value mail before March 1 (A.R.S. §42-15101), so the 60-day petition window usually closes by late April. The deadline is printed on your notice.

How to file in Yuma County
- Step 1
File the appeal
Use the method your notice lists, usually Form 82130R, by the deadline on the notice.
- Step 2 · before the hearing
Prepare and submit your evidence
The petition must state your opinion of full cash value and the information behind it (A.R.S. §42-16051): for a home, at least one comparable property’s value or sale in your area, or your own recent purchase. Appeal the total value, not land and improvements separately. Issues you do not raise with the assessor generally cannot be raised later at the board (§42-16056), so put all of it in the first petition.
- Step 3
Meet, then hear
An petition for review with Yuma County Assessor's Office comes first; if you decline the offer, the Yuma County Board of Equalization hears the case. Most reductions happen at the first step.
