Property Tax Rolls

What are property tax rolls?

In Ada County, there are three (3) property tax rolls. A property tax roll is simply a bill that corresponds to specific assessment periods. Each property tax roll is created annually by the Ada County Assessor’s Office. The Assessor’s Office is responsible for determining each property’s appraisal value and its property tax, which is all detailed on the roll.

 

Why did I receive an additional property tax bill?

Additional tax bills may be sent if you occupied a newly constructed home or made improvements to your property. See Tax Rolls below to determine which apply to your situation.

Every Ada County property owner will receive a bill* yearly in late November detailing the taxing districts, levy rates, and the amount of property taxes owed for properties that are assessed between January 1st and the fourth Monday in May.

*Note: If a lender requests a bill, the property owner on record will receive a copy bill to make the property owners aware of the amount of taxes owed and what will be paid from their escrow account. When you get your property roll bill, please make sure the correct lender is listed under “Who Requested My Bill?” or on the return coupon. If a property owner does not have an escrow, they will receive a standard bill. Please notify our office if you have paid off your mortgage or are now otherwise responsible for making property tax payments. 

If new construction is completed and occupied between May’s Property Roll closure and November, the property owner will receive a Subsequent Roll assessment no later than the 3rd Monday in November (usually earlier), followed by a tax bill in January.  The first half payment of the Subsequent Roll tax bill will be due in February (please refer to your Subsequent Roll tax bill for the exact due date). This bill is in addition to any charges related to Property Roll assessments.

If a property is assessed between the Subsequent Roll’s closure and December 31st, the property owner will received a Missed Roll assessment no later than the first Monday of January (usually earlier), followed by a tax bill in February.  The first half payment of the Missed Roll will be due in March (please refer to your Missed Roll tax bill for the exact due date).  This bill is in addition to any charges related to Property and Subsequent Roll assessments.

If property owners or lenders choose to pay property taxes in halves, the first half is due by December 20th of the current year, and the second half is due by June 20th of the following year.

Note: If a property owner has paid off their mortgage but a lender requests the Reminder Notice, property owners will not receive any additional reminder documentation. Please remember that failure to mail or receive any tax notice does not excuse the timely payment of taxes (Idaho Code 63-902.10).
