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.
You must file Form 967 annually to reconcile your withholding account regardless of your filing cycle for Form 910.
Monthly filers: You must file Form 910 monthly if you're in one of these situations:
- You withhold less than $20,000 a month and more than $750 a quarter.
- You have only one monthly pay period.
Semimonthly filers: You must file Form 910 twice per month if you're in one of these situations:
- You withhold at least $240,000 in a 12-month period.
- You withhold at least $20,000 per month.
Quarterly filers: You must file Form 910 quarterly if you're in one of these situations:
- You withhold $750 or less each quarter.
- You're a farmer who's required to file with the Idaho Department of Labor.
Annual filers: You must file Form 910 once per year if you're in one of these situations:
- You withhold less than $750 annually.
- You're a farmer who isn't required to file with the Idaho Department of Labor.
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.
- Email: email@example.com
- Fax: (208) 334-7650
- Mail: Idaho State Tax Commission, Permit Accounting, PO Box 36, Boise ID 83722-3220
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.
