Ada County Commissioners
For questions regarding property tax exemptions in Ada County, please contact the Commissioners’ Office at 208 287-7000. The deadline for filing tax exemptions is MONDAY APRIL 15, 2020. Please include by-laws, articles of incorporation, financial statements and any other documents that support your request for exemption. Organizations must apply each year for an exemption. Just because you may have been previously exempt, it does not carry over to the next year.
Note: No late tax exemption applications/forms will be accepted.
You may download or print an Application and Worksheet (see item 12 on the Application to determine which Worksheet is appropriate) and return them, with supporting documents, to the Board of Ada County Commissioners at 200 West Front Street, 3rd Floor, Boise, Idaho 83702. If you prefer, you may fax the documents to the Commissioners’ office at 208 287-7009.
