A late charge equal to 2% of any unpaid portion of the first half of the tax is added at 5:00 p.m. on the due date. Interest accrues daily at 1% per month, on a per diem. The rate is .032854 beginning January 1st of the year following the December 20th first half due date.

When any portion of a manufactured home or personal property tax becomes delinquent, a Warrant of Distraint is issued to the County Sheriff for collection. Full payment of all tax, late charge, warrant fees and interest is required to release the warrant.

Ada County charges property taxes in arrears. For example, when you receive a tax bill in November the taxes owing are for that current year.

DUE DATE

• OPTION #1: Pay the whole amount by Dec 20th
• OPTION #2: Pay the first half on Dec 20th and second half on June 20th without penalties and interests.

Tax payments are governed by title 67 Idaho Code. Property taxes are due no later than December 20th, however, you may pay ½ of the total taxes due no later than December 20th; and use a grace period to pay the second ½ no later than June 20th of the next year. If ½ payment is not received by December 20th, your property tax bill is considered delinquent.

DELINQUENT PROPERTY

Partial payments toward real property delinquent taxes are accepted (any amount, any time) and are applied to tax, costs, interest and late charge in the proportion each bears to the total amount due.

PAYING FOR FUTURE TAXES

Partial payments of at least $25 can be applied toward current year or future taxes on all property types. Any remaining balance may be paid according to the standard schedules and regulations for property tax collection.

BUSINESS PERSONAL PROPERTY OR MANUFACTURED HOMES

Once any part of a personal property or manufactured home tax becomes delinquent, the unpaid portion of the entire tax shall immediately become due and payable.

An appeal of the taxable value of your property must be submitted by the 4th Monday in June. This appeal may be made by filing an appeal with the Board of County Commissioners. If you did not appeal the current year value during this time period, you must wait until next year to appeal the assessed value. Call the area appraiser listed on your assessment notice to begin the process.
If you feel that the levy of a taxing district is too high or you wonder what the levy pays for, call the district directly. The phone numbers of all of the taxing districts within Ada County can be found on your tax bill or your assessment notice.
