Quick answer
Idaho payroll tax registration at a glance
Idaho employers register through one Idaho Business Registration (IBR) application. If you have employees, IBR gets you an income tax withholding account with the Idaho State Tax Commission plus permits from the Idaho Department of Labor (IDOL) and the Industrial Commission. You need a federal EIN first.
In 2026, unemployment tax applies to the first $58,300 of each employee's wages. New employers start at the standard rate, 1.000% in 2026, for at least their first six calendar quarters. New hires go to IDOL within 20 days.
Who must register
Who registers in Idaho
Most employers need both accounts.
| Situation | Idaho requirement |
|---|---|
| You withhold Idaho income tax from wages | Get an EIN, then register for a withholding account through IBR |
| You pay $1,500 in wages in a calendar quarter, or have a worker in 20 different weeks of a year | You are covered for Idaho unemployment insurance |
| You become a covered employer | Submit the IBR form within six months of becoming covered, or face penalties of up to $500 |
| You acquire a business that was already a covered employer | You are covered right away and report all wages |
| You hire or rehire employees | Report them to IDOL |
| You have one or more employees, full-time, part-time, seasonal or occasional | Carry workers' compensation insurance before the first employee is hired, unless exempt |
Registration steps
How to register in Idaho
One application, then new hire reporting.
- Get your federal EIN from the IRS. The Tax Commission requires it before you apply for a withholding account.
- Register your business and any assumed business names with the Idaho Secretary of State.
- Submit the IBR application at business.idaho.gov. Use the same employer name and EIN you'll put on W-2s. Online applications get permits in 10 to 15 business days; mailed ones can take up to four weeks.
- Set up your IDOL Employer Portal account to file quarterly unemployment reports online.
- Report each new hire and rehire to IDOL within 20 days of the hire date.
- Watch for your filing cycle. The Tax Commission assigns your Form 910 cycle and sends instructions for setting up a TAP account.

Pitfalls
Idaho mistakes to avoid
Most problems come from missed dates and zero filings.
- Skipping zero filings. File a "zero" Form 910 when you didn't withhold, and file IDOL quarterly reports even with no wages.
- Counting on a grace period. IDOL reports and payments are due the last day of the month after the quarter, with no grace period.
- Registering late. The IBR form is due within six months of becoming a covered employer, with penalties of up to $500.
- Reusing an old account after a change. A new EIN, an acquisition or a new entity type needs a new withholding account.
- Missing the annual reconciliation. Form 967 is due every year, whatever your Form 910 cycle.
Related duties
Other Idaho employer obligations
These run alongside the tax accounts.
- New hire reporting. Report new hires to IDOL within 20 days of the hire date, plus rehires whose prior job ended at least 60 days earlier. Electronic reporters send two transmissions a month, 12 to 16 days apart.
- Workers' compensation. Employers with one or more full-time, part-time, seasonal or occasional employees must have a policy in place before the first employee is hired, unless specifically exempt.
- Online UI filing. IDOL requires online quarterly reporting unless you get written approval to file on paper.
Filing calendar
Idaho deadlines after registration
Your Form 910 cycle sets the payment dates.
- Semimonthly filers (at least $25,000 a month, or $300,000 in 12 months): by the 20th for the 1st through 15th, and by the 5th of the next month for the 16th through month-end.
- Monthly filers (under $25,000 a month and over $750 a quarter): by the 20th of the next month.
- Quarterly filers ($750 or less each quarter): by the last day of the month after the quarter.
- Annual filers (under $750 a year): by the last day of January.
- Form 967 and W-2s: by the last day of January. 1099s are due the last day of February.

Idaho registration questions
How do I register for Idaho payroll taxes?
Get a federal EIN, then submit the Idaho Business Registration (IBR) application. If you have employees, it sets up your Tax Commission withholding account and your Idaho Department of Labor permits.
How long does Idaho registration take?
The Tax Commission says permits arrive in 10 to 15 business days when you apply online, and up to four weeks by mail.
What is the Idaho new employer unemployment rate?
For 2026 the standard rate is 1.000%, applied to the first $58,300 of each employee's wages. New employers keep it for at least their first six calendar quarters.
How fast must I report new hires in Idaho?
Within 20 days of the hire date. Rehires count when the prior job ended at least 60 days earlier.
How often do I file Idaho withholding?
It depends on how much you withhold: semimonthly, monthly, quarterly or annually on Form 910, plus an annual Form 967 for every employer.
Do I file if I didn't withhold anything?
Yes. File a "zero" payment form for the period, and keep filing IDOL quarterly reports even with no wages.
I am the only employee of my S corporation. What do I need in Idaho?
If you pay yourself wages, you need the withholding account. IDOL treats corporate officers as employees, and an officer can file an exemption form by March 31 to opt out of state unemployment reporting for two calendar years. A dedicated tax manager can complete the registrations with you as part of our S corp payroll package.
How is registration priced?
Most states issue two IDs, one for withholding and one for unemployment insurance. Pricing depends on the states and accounts involved. We'll quote it on a quick consultation.
Is this tax advice?
No. It summarizes official guidance from Idaho state agencies. Ask your CPA or tax advisor about your own facts.
