Estimate your property taxes at

BOISE, IDAHO — June 18, 2020 — Did you know that an increase in a property’s value won’t automatically equal a tax increase? 

To find out the impact of rising property values on them, residents in 29 Idaho counties now can estimate their 2020 property taxes by using a calculator on the Idaho State Tax Commission’s website at The calculator also is available through a link on the “Quick Picks” section of the home page. Your assessment notice has the value and tax code area information needed to use the estimator.

Estimates provided by the calculator might not include levies for new taxing districts and recent voter-approved funds. They also don’t include fees (e.g. solid waste, forest protection) that may be billed on tax notices. Please contact your county treasurer for a list of fees in your area.  

Actual tax amounts will be determined after cities, counties, and other taxing districts set their budgets in late summer.

The tax estimator is a joint effort between the Tax Commission and these participating counties: Ada, Adams, Bannock, Bear Lake, Benewah, Bingham, Blaine, Boise, Bonner, Bonneville, Boundary, Butte, Canyon, Caribou, Cassia, Clark, Clearwater, Elmore, Franklin, Jefferson, Jerome, Latah, Minidoka, Nez Perce, Owyhee, Power, Twin Falls, Valley, and Washington. Idaho’s other 15 counties don’t contribute their data to the tax estimator service.
