Ada County Property Tax Calculator Now Available


(Boise, ID) – The Ada County Treasurer’s Office is excited to announce a new online tool!

Property owners are now able to calculate the current year tax amount that’s due online at adacounty.id.gov/treasurer . They’re also able to calculate a future interest amount if their taxes are delinquent. Tax information calculated using this tool represents the property tax owing as of midnight the day prior. Delinquent taxes accrue interest at 1% per month calculated from January 1st.

This tool can only calculate the current year tax amount. Taxpayers can obtain the outstanding balance for prior years by submitting their request to https://adacounty.id.gov/treasurer/tax-information-form/ or by calling  208-287-6800.


For important information, visit our website adacounty.id.gov/Treasurer or contact the Ada County Treasurer’s Office at 208-287-6800.
