Extended deadline nears for filing income tax returns

Tuesday September 27, 2022

BOISE, Idaho — Sept. 27, 2022 — Time’s running out to file your 2021 Idaho income tax return. The Idaho State Tax Commission says taxpayers who qualified for an automatic extension to file must send in their return and full payment by October 17.

“We expect to receive about 36,000 individual income tax returns in October,” Tax Commission Chairman Jeff McCray said. “That’s in addition to the 925,000 returns we’ve received so far this year.”

Idaho law allows you to avoid a penalty for filing a late return if you have an extension. But you’ll still owe 3% interest on any income tax due that you didn’t pay by April 18, the original due date.

You can file your income tax return electronically, and you might qualify to prepare and file it online for free. Visit to learn more.

You also can pay taxes electronically through The free Quick Pay option lets you make a payment without creating a special account.

If you qualify for Idaho’s two 2022 tax rebates, you’ll receive them after the Tax Commission has processed your 2021 tax return.
