Under current law, residential real property that is classified as qualified-senior primary residence real property is subject to a reduced valuation for assessment for property tax years beginning on or after January 1, 2025, but before January 1, 2027. The act ends the qualified-senior primary residence real property classification for property tax years beginning on or after January 1, 2027, and changes related requirements for county assessors, county treasurers, and the property tax administrator so that the classification and all related administrative and reporting requirements end on dates that align with the end of the reduced valuation for assessment. The act changes the state property tax exemption for business personal property, commencing on and after January 1, 2027, by setting the exemption at $58,000, without an adjustment for inflation. The act also sets the reimbursement for property tax losses due to the exemption, for property tax years beginning on and after January 1, 2027, at the reimbursement amount for the 2026 property tax year.(Note: This summary applies to this bill as enacted.)
