The Sarpy County property valuation protesting period is open June 1 through June 30.
The county assessor has sent property owners who owned property as of May 20, 2026, a Notice of Valuation Change if their assessed value increased or decreased from tax year 2025 to 2026.
If you are not satisfied with your property's assessed valuation and choose to file a protest, you must complete Protest Form 422 and file it with the Sarpy County Clerk’s Office.
The forms are due June 30 in person by 4:45 p.m. or if filing online by 11:59 p.m. Forms submitted by mail must be postmarked no later than June 30. (Keep in mind that under updated guidance, the U.S. Postal Service cannot guarantee that the date a piece of mail is dropped in a box or given to a carrier will be the date reflected on the postmark.)
The Sarpy County Board of Equalization bases its final valuation decision on data from the County Assessor's office, data presented by each protester and the recommendation of an independent appraisal company.
