Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Custer County Assessor / Custer County Treasurer.

No county-specific annual valuation cap was verified. Nebraska residential and commercial real property is generally assessed at 100% of market value and agricultural special valuation at 75% of agricultural market value; consolidated local tax districts set tax rates. Nebraska homestead maximum-value limits affect exemption eligibility, not the assessed-value roll.

Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: On or before June 30, 2026; Custer County requires Form 422 filed in triplicate with the County Board of Equalization at the County Clerk’s office. Official page: https://custercountyne.gov/county-assessor/property-valuation-protests/.
