Helpful Tips on Preparing for Property Taxes

Your Ada County Consolidated Property Tax Bill will be mailed out by the 4th Monday in November. Property Taxes directly affect all of us, so we want to make sure families and individuals understand payment options, and how those tax dollars are distributed.

Be sure to listen to “Idaho Matters” on Boise State Public Radio Today (Tuesday, November 12th) at 12:00 pm by tuning into 91.5 FM or by streaming online at: Boise Public Radio’s Website

Ada County Treasurer Elizabeth Mahn and Ada County Assessor Robert McQuade will join host Gemma Gaudette to discuss what you need to know about property tax bills.

It’s never too early to start preparing for property tax deadlines. Tax bills for the primary assessment roll will be mailed on or before the fourth Monday of November in accordance with Idaho Code 63-902.

1. Sign up for Ada County’s Property Portal which allows you to register for e-mail and/or text notifications when your tax bill becomes available to view electronically.

You’ll continue to receive a paper bill, but given that things can happen during the mailing process there is always a chance the bill doesn’t reach you. This portal serves as an extra tool for accessing information regarding your property. Please remember, failure to receive a tax bill does not excuse the taxpayer from paying the taxes, late charges and interest accured if any (Idaho Code 63-902(9)).

Please note:

  • If you are responsible for paying your property taxes or they are paid through escrow by a mortgage lender, you can also view any delinquent notices on your parcel.
  • If you recently paid off your mortgage and did not notify us of this change before November 1, please contact our office for the current status of your taxes.

2.  Complete any mailing address changes with the Assessor’s Office right away to help ensure documents reach you properly.

3. If planning to use online bill pay through your banking institution, remember to verify your parcel number prior to any payments.

Other Ways to Pay Your Bill

Property Taxes on New Construction

Primary Roll: If you are the property owner of new construction you will receive a property tax bill for the land and any structure on the property prior to improvements starting.

Subsequent Property Tax Roll or Occupancy Roll: If construction is completed after the primary roll assessment deadline of May then you will receive a tax bill for the improvement or structure in January which will be due by February 20, 2019.

Missed Roll: The Assessor’s Office may reassess the property from date of ownership change to December 31. This generates a missed roll bill sent in February and due by March 20, 2019. If a developer owned the property they may have a “developer’s exemption”. Once ownership changes the exemption is no longer applicable.
