Welcome to the Ada County Treasurer’s Office! You now have the ability to view your property tax assessment notices and property tax bills electronically. As part of this service, you can also provide your cell phone number and/or email address when you register your account to receive an alert when these documents are ready for review. We are excited to introduce this new service to taxpayers and it’s our vision to continue implementing innovative solutions which provide more effective and efficient services.

Want to make an online payment? When processing debit or credit cards a convenience fee of 2.4% of the transaction amount will apply or you can process an e-check for a flat fee of $3.00.


The 2nd half tax payments need to be postmarked by the US Postal Service by 5:00 pm on June 20, 2019, to avoid late fees and interest. (In house mail meters are not proof of a timely payment)

Other Ways to Pay Your Bill

Remember to Reference Your Parcel!

Tax bills are mailed to each parcel. Failure to receive a tax bill does not excuse a taxpayer from paying the taxes, late charges or interest accrued.

Understanding Property Taxes on New Construction Homes

  • 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 Once ownership changes the exemption is no longer applicable.
