Qualified for a 2021 Idaho income tax return extension? Your deadline is coming soon.

The clock is ticking for Idahoans to file 2021 income tax returns who qualified for an extension. The Idaho State Tax Commission says those who qualified for an automatic extension must send in their return and full payment by Oct. 17, according to a news release.

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

Idaho law allows taxpayers to avoid a penalty for filing a late return if you have an extension. However, those who qualify for the extension owe 3% interest on any income tax due that they didn’t pay by April 18, the original due date, the news release said.

You can file your income tax return electronically, and you might qualify to prepare and file it online for free at tax.idaho.gov/freefile.

You also can pay taxes electronically through tax.idaho.gov/epay. The free quick pay (https://idahotap.gentax.com/tap?Link=QuickPay) 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. The tax commission has an online tool where Idahoans can track the status of their rebates at tax.idaho.gov/rebate.
