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.
