Tax Commission News Release

Idaho’s income tax, property tax relief applications deadlines extended to May 17

BOISE, IDAHO — March 25, 2021 — The Idaho State Tax Commission voted today to extend the 2020 Idaho income tax filing and payment deadlines from April 15, 2021, to May 17, 2021, to match the federal extended deadline. 

The extension applies to all taxpayers subject to Idaho’s individual income tax (i.e., individuals, trusts, and estates), regardless of the amount owed. Penalty and interest won’t apply if taxpayers file their return and pay the income tax they owe by May 17.   

Governor Brad Little asked the Tax Commission to conduct a special meeting on extending the filing deadline.

The Tax Commission’s resolution also extended the deadline to apply for property tax relief programs from April 15 to May 17. The programs include:

  • Property Tax Reduction (circuit breaker)
  • Property Tax Deferral 
  • 100% Service-Connected Disabled Veterans Benefit

E-filing your return remains the safest and easiest way to file. The software walks you through the steps and does the math for you. You also get confirmation that the state received your return. 

The Tax Commission website – – includes links to software providers offering free e-filing options for many people with an adjusted gross income of $72,000 or less. 

If you’re expecting a refund, 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 when filing your individual income taxes.

If you owe tax, you can schedule electronic payments on dates you choose by using the website’s free Quick Pay service or through e-file providers that offer a free direct debit option. You can use either option to spread out payments until the May 17 due date.
