Amends existing law to revise provisions related to the assessment of market value and the homestead exemption.
House Bill 354 revises several Idaho property tax provisions. It directs the State Tax Commission to update market-value assessment rules, including requiring assessors to use recognized appraisal methods, consider actual and functional use as a major factor, and apply statistical testing to ensure assessed values stay within a specified range of market value. For income-producing property, it limits market value calculations by excluding contract rent tied only to the real estate and exempt intangible personal property, and requires assessors to provide owners with the calculations used on request.
The bill also changes the property tax appeal process and homestead exemption administration. It adjusts appeal rules from county boards of equalization to the Board of Tax Appeals or district court, clarifies burden-of-proof rules, and adds a special burden-shifting rule when a valuation increase over 10% results from an assessor’s failure to use required equalization methods. For the homestead exemption, it preserves the existing exemption amount but revises eligibility, application, proration, recovery, penalty, lien, and appeal procedures, including stronger enforcement against multiple or improper claims and continued coordination with voting-residence verification. It also amends the property tax payment deadline provisions to align with the new homestead-related timing rules, and the act takes effect January 1, 2026.
The bill amends Idaho Code sections 63-208, 63-511, 63-602G, and 63-903. Its practical effect is to tighten assessment standards, expand disclosure to property owners regarding valuation calculations, refine appeal procedures, and modernize homestead exemption administration and enforcement. It also affects county assessors, county auditors, county treasurers, the State Tax Commission, the Board of Tax Appeals, and property owners claiming the homestead exemption or appealing assessed values.
The available voting history shows strong bipartisan support and no recorded opposition in either chamber: the House passed the bill 69-0 and the Senate passed it 34-0. No committee transcript is available, but the unanimous votes suggest the bill was viewed favorably as a technical and administrative update to property tax law rather than a controversial policy change.
No explicit contention appears in the available record. The most likely areas of interest are the bill’s stricter assessment methodology, the burden-shifting rule for certain valuation increases, and the enhanced enforcement provisions for homestead exemptions, including penalties for multiple claims and information-sharing tied to voting residence. These provisions could matter most to county assessors, taxpayers challenging valuations, and homeowners claiming the exemption, but the unanimous votes indicate no visible legislative division.
