- IdahoInfo
The State of Idaho collects no property tax; counties assess and levy it locally. Property is assessed at 100% of market value as of January 1, less exemptions. The homeowner's exemption removes 50% of an owner-occupied home's value plus up to one acre (capped at $125,000) from the taxable amount. Local taxing-district budgets set the rate.

- OregonInfo
County-administered: county assessors value property and collect the tax for 1,200+ local taxing districts. Tax applies to the lesser of real market value or maximum assessed value — MAV growth is capped at 3%/year (Measure 50) — with district permanent rate limits and Measure 5 category limits ("compression"), so bills do not track market value directly. Appeals go to the county Property Value Appeals Board by Dec. 31.
