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 16, 2018. 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.
Please note it is your responsibility to apply each year, however.
A complete copy of Idaho Code, Title 63, Chapter 6 may be available at your local library, or you can review the code online on the State of Idaho webpage
