What are property taxes like in Caldwell, Idaho?

How much might that be on a typical home?

It depends on the property's assessed value, any exemptions, and its tax area. As an illustration only: on an owner-occupied home assessed at $400,000, the Idaho homeowner's exemption (the lesser of 50% of assessed value or $125,000 — confirm the current cap on the Tax Commission site) would reduce taxable value to $275,000. At the 2026 range of about 0.66% to 0.73%, the annual property tax would be roughly $1,800 to $2,005. A home that does not qualify for the exemption would be taxed on a larger taxable value. The county's figures control the actual bill.

This is general information, not tax advice. Rates and exemptions change. Verify current figures independently with the Canyon County Assessor or Treasurer, or the Idaho State Tax Commission.
