Assumptions

  • Tax rate. 68.5 mills, the statewide average levy (68.504) used in the Legislative Service Office's fiscal note for SF 69, based on tax year 2024. Local levies vary.
  • Stacking. This scenario assumes the 25% exemption stacks with Prop 1, which is how the law reads if the Legislature doesn't change it. Each is figured on the value before any exemption, so they add. On a home under the $1M cap, that exempts 75% of the structure. Pending proposals would instead repeal the 25% exemption or make owners choose one.
  • Best choice. The owner is assumed to claim whichever eligible combination saves the most. An owner who claims the long-term exemption can't get the 25% (SF 69) or Prop 1 (HB 45, 2026).
  • Caps. The 25% exemption's $1M cap and the long-term exemption's $3M cap apply to home and land together. Where a cap binds, the exempt amount is split between home and land in proportion to value. The statutes don't say how to split it.
  • Not modeled. The 4% annual caps on growth in residential value, the veterans' exemption, and other credits and refund programs. Agricultural land is valued on what it produces and is outside these exemptions. The ranch presets treat the land as residential.
  • Property type. The 25% exemption covers single-family homes, including mobile homes, townhouses and condos. Prop 1 also covers a home in a multi-family building, one exemption per building. The calculator assumes a single-family home.
  • Timing. Prop 1 is on the Nov. 3, 2026 ballot. This page assumes it passed. The Secretary of State expects it to apply first in tax year 2027.
