Tax Commission News Release

File Idaho income taxes starting Jan. 29

BOISE, IDAHO — Jan. 23, 2018 — The Idaho State Tax Commission will start to process 2017 Idaho individual income tax returns on Monday, Jan. 29. This is the same date the Internal Revenue Service begins to process federal returns.  

As in past years, all Idaho tax returns will go through identity theft fraud detection and accuracy checks. Before issuing your refund, the Tax Commission may ask you to:

  • Verify that you filed a return
  • Verify your identity
  • Provide more information

E-filing your return is the quickest way to receive a refund. Using direct deposit for your refund gets the money to you even faster.  

Typical Refund Timeframes

E-filers: Expect your refund about seven to eight weeks after the date you receive a filing acknowledgement from the state.

Paper filers: Expect your refund about 10-11 weeks after the Tax Commission receives your return.  

Refund Exceptions

First-time filers: It takes about three weeks to enter your account into the Tax Commission’s system. Until that time, any refund update will report your return as “not entered in system.” Add those three weeks to the estimates above to determine your refund timeframe.

Received a Tax Commission letter asking for more information: Your refund will be delayed until the Tax Commission gets the requested information. It will then take about six weeks to review your material and finish processing your refund.  

You can check your refund status by visiting You can also get help through the website or by calling (208) 334-7660 in the Boise area or toll-free at (800) 972-7660.
