Wyoming Property Tax Appeal Guide
Deadline varies by county — check your county's appraisal district.
| Deadline | File a written statement of disagreement with the county assessor no later than 30 days after the date the assessment notice (assessment schedule) is mailed. Assessment schedules are mailed on or before the fourth Monday in April, so the actual deadline rolls 30 days off each county's mail date. A taxpayer who timely files is heard by the county Board of Equalization (county commissioners sitting as the board); the board notifies parties of its findings no later than the first Monday in August. — Wyo. Stat. §39-13-109(b)(i); §39-13-103(b)(iii) |

How to Appeal in Wyoming
File your appeal with your county's County BOE by the deadline above. Contact your local county assessor's office for the specific portal or form required in your county.
If your appeal is denied, escalation options include: Informal review with the county assessor — file a written statement of disagreement (on the assessor's form or by letter) within 30 days of the assessment-notice mail date; the assessor and protestant exchange evidence no later than 30 days before the county board hearing → County Board of Equalization — the county commissioners sit as the board and hear timely appeals (typically mid-June), issuing findings no later than the first Monday in August → Wyoming State Board of Equalization — appeal of a county board's final decision, filed within 30 days from the date the decision is entered or mailed, whichever is later (Wyo. Stat. §39-11-102.1; §39-13-109) → District court — judicial review of the State Board of Equalization's final decision under the Wyoming Administrative Procedure Act → Wyoming Supreme Court — appeal from the district court's judgment on review.
