Filing withholding returns

We'll send your personalized Idaho withholding forms after you register with the Tax Commission (see "Apply for a withholding account").

Don't mail paper forms if you file electronically.

If you can't find your personalized form and you want to file on paper, contact us and we'll mail you a new copy. Always use the personalized form that's both:

  • Preprinted with the correct period
  • Preprinted with the correct employer name and account number

Note: Printable withholding forms aren't available on the Tax Commission's website because they're personalized.

Filing cycles
Form 967

You must file Form 967 annually to reconcile your withholding account regardless of your filing cycle for Form 910.

Request a change to your filing cycle

Withholding account cycles are effective for a full calendar year. We'll change your filing cycle at the end of the year for the following year, if appropriate.

You can request a change to your filing cycle. You must send it by November 15 for the change to take effect for the following year.

Due dates

You must forward the withheld Idaho income taxes based on the account filing cycle the Tax Commission assigned to you (see Idaho Code section 63-3035). Report and forward taxes based on when you paid the wages, not when the employee earned them. You must file a "zero" payment form if you didn't withhold Idaho income taxes.
