Idaho homestead exemption

  • Idaho's homeowner's exemption takes the lesser of $125,000 or 50% of market value off an owner-occupied primary home.

This is the property tax homestead exemption, not the homestead exemption that protects a home from creditors in bankruptcy.

Does Idaho have a homestead exemption?

Idaho's homeowner's exemption takes the lesser of $125,000 or 50% of market value off an owner-occupied primary home. The calculator does not subtract it: the rates already reflect the exemptions owners received.

Why might a Idaho tax bill differ from this estimate?

The rate is what owner-occupiers in Idaho paid on average in 2020 through 2024, as a share of their homes' value. An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.

What the calculator leaves out

  • The rate is the total real estate tax owner-occupiers reported paying divided by the total value they reported for their homes, not a tax rate set by law.
  • The rate already reflects the exemptions, caps and credits typical owner-occupiers received, so the calculator does not subtract a homestead exemption again.
  • An actual bill depends on the home's assessed value, the levies where it sits and the exemptions its owner claims.
  • Survey estimates for small counties have wide margins of error.

Rates and medians are American Community Survey 2020-2024 5-year estimates: taxes owners paid in those years, not 2026 bills.
