Idaho State Tax Commission


Filing information returns (1099s, 1098, W-2Gs)

Copies of these forms are due to the Tax Commission by the last day of February.

How to file

1099s are information returns you use to report certain payments and services.

Form 967 and W-2s are due by the last day of January, and 1099s are due by the last day of February. If you have 1099s to file, you can use one of these options:

  • File all forms (967, W-2s, and 1099s) by the last day of January.
    • Following this schedule can help you reconcile your withholding because you'll be working with all your records at once.
    • You can file online using TAP, or you can file by paper.
  • File your Form 967 and W-2s by January 31, and file your 1099s by the last day of February.
    • Make sure to include the amount of Idaho withholding from the 1099s along with the withholding from the W-2s in the "Total Idaho Tax Withheld" amount you reported on the Form 967.
    • Also, include the number of 1099s with Idaho withholding on Form 967.
    • If you're participating in the Combined Federal/State Filing program, check the appropriate box on the form.
    • Read "Filing 1099s in February," below.

1099 Combined Federal/State Filing program

This program allows payers and agents to file an information return with the federal government, and it authorizes the release of this information to the applicable states. You must get permission from the IRS in advance to participate. See IRS Publication 1220.

If your information returns have Idaho withholding, you must complete Form 967, Idaho Annual Withholding Report.

If you file your 1099s and other information returns through the Federal/State Combined Filing program:

  • Don't file 1099s electronically through the Tax Commission's website.
  • Don't submit paper copies of 1099s with your Form 967.
