Park County property tax appeals
The 2026 deadline was Wednesday, May 27 and has passed. The next window opens in 2027.
Appeals go to Park County Board of Equalization.
Wyoming values property each January and gives owners 30 days from the assessment schedule to appeal.
- Sales evidence shows fair market value is too high.
- The assessor's property record is wrong.
- The complaint is only about the tax bill.
- You miss the 30-day schedule window.
Read the full explanation
Wyoming county assessors determine fair market value as of January 1 each year and mail assessment schedules by the fourth Monday in April. To contest the value, an owner files a written statement with the assessor within 30 days after the schedule's date or postmark, whichever is later. County commissioners sit as the county board of equalization. This is general information, not tax advice.
