Bill Overview

Analyzed Economic Effects

6 provisions identified: 4 benefits, 0 costs, 2 mixed.

Counties can choose alternate tax protests

Beginning January 1, 2027, counties can choose an alternate property tax protest and appeal process at the assessor’s request. The county must choose by May 1 for that year. Its choice can cover real property, personal property, or both. In counties using this process, personal-property protest hearings must end by July 31.

Higher local limits for property tax refunds

The law raises the local property tax refund or reduction threshold from $10,000 to $20,000 per tract, parcel, lot, or personal-property schedule. Assessors can settle claims up to that amount by written agreement. County boards recommending more than $20,000 must send one application to the state property tax administrator, electronically or on paper. No application is required for valuation changes that ensure matching values within the same reassessment cycle.

Later deadlines for some valuation appeals

After a county board denies all or part of your valuation petition, the latest applicable deadline controls further review. The dates are September 1, or December 1 in counties using the alternate process. For notices outside the regular schedule, the appeal-or-arbitration deadline also allows 30 days after the denial is mailed. For appeals to the state assessment appeals board, that 30-day window runs from the board’s decision. The latest applicable date governs in each case.

Simpler forms and fairer valuation hearings

The state property tax administrator must publish standard forms and instructions for every appeal level, including a letter of authorization. Notarization is unnecessary when the administrator’s guidance allows other reliable ways to confirm authenticity. County boards must weigh valuation evidence without assuming the current valuation is correct. The state assessment appeals board must treat hearing requests as timely unless it presents evidence otherwise.

Senior homeowners get limited late filing

Beginning January 1, 2027, applications for qualified-senior primary-residence classification are due July 15. Assessors must accept late applications through August 15. However, the assessor’s decision on any application filed after July 15 is final and cannot be challenged. This includes applications filed after August 15.

Taxpayers get arbitration deadlines and limits

To choose arbitration, notify the county board by the latest applicable date: September 1, or December 1 in alternate-process counties. For off-schedule notices, the deadline also allows 30 days after the board’s decision. You and the board must select an arbitrator within 15 days after your notice or 30 days after the annual list becomes available, whichever is later. If you cannot agree in time, the district court chooses an arbitrator from the list. Arbitration is final and cannot be reviewed further.
