Idaho state payroll taxes and paycheck rules

What’s the salary threshold in Idaho?

Because the state of Idaho doesn’t have its own salary threshold, it adheres to the federal salary threshold, which is now $684 per week (equivalent to $35,568 per year for a full-year worker). The Department of Labor permits employers to count some bonuses, commissions, and other incentive payments toward meeting the standard salary level (up to 10%). Employees who earn at least $107,432 per year may qualify as “highly compensated.” See this Department of Labor fact sheet for details.

Do new employees need to be reported to the state?

Yes, you must report new hires. Employers have 20 days from the newly hired or rehired employee’s hire date to report them to the Idaho Department of Labor. 

When do Idaho employers need to have Workers’ Compensation insurance?

Requirements to obtain Workers’ Compensation vary by state, this table outlines some of these requirements. If you determine that your company is required to purchase Workers’ Compensation insurance in your state, learn how to sign up for this insurance with Gusto. Sometimes, companies get a request for a workers’ comp audit—head to this article and click the workers’ comp audit reports dropdown for more information.

When do final wages need to be paid?

Anytime an employee leaves, their final paycheck is due by the next regularly scheduled payday or ten days after separation, whichever is sooner. 

How is Idaho’s unemployment tax calculated?

When a new business registers for an unemployment account, it’s assigned a standard tax rate. For 2022, that rate is 1% for at least the first six calendar quarters. After that, employers are assigned an experience rate that reflects their use of the unemployment insurance system. Experience rates range from 0.207% to 5.4%. The Idaho Department of Labor mails rate notices to employers each December.

Idaho’s unemployment tax is charged on the first $46,500 of each employee’s wages each year. This number, called the wage base, can change each year. Idaho requires employers to pay their taxes and file their wage reports online

How do I know how much tax to take out of employees’ paychecks for state income taxes?

You need to get some information from your employee before you can calculate the withholding tax amount.

Have employees fill out Form ID W-4, Employee’s Withholding Allowance Certificate, when they start working for you. Information like tax filing status and the number of allowances are on this form and are needed to figure out the tax amount.

Idaho has several methods you can use to compute the withholding tax. They include:

  • Percentage computation method
  • Annualized wage method
  • Wage bracket method

Each method uses information from Form ID W-4 and some charts and formulas to calculate the amount to be withheld. But an easier way is to use payroll software to automate the calculations for you.

How to pay

You’ll need to send the taxes you collect to the Idaho State Tax Commission. How often you need to pay depends on the amount of tax owed. Payment frequencies can be:

  • Semi-monthly
  • Monthly
  • Quarterly
  • Annually

You have the option to pay by check or online

How to file

Payroll tax returns also need to be filed.

    • When to file:
      • Each time you make a payment or
      • When no payment is due because no wages were paid

Federal payroll taxes in Idaho

How do employers know how much tax to take out for federal taxes?

It starts with getting Form W-4, Employee’s Withholding Certificate, from employees when you hire them. Information on this form is critical for making an accurate tax calculation. Using this information and the federal tax tables, you can figure out how much tax to withhold. 

How is the FICA tax calculated?

The Federal Insurance Contributions Act, or FICA tax, is made up of the Medicare tax and the Social Security tax. In 2022, the Social Security tax requires employers and employees to each contribute 6.2% of wages up to $147,000. The Medicare tax requires each to contribute 1.45% of all wages. See the IRS webpage for details, like maximum thresholds.

Who pays the Additional Medicare tax?

Do employers need to pay federal unemployment tax if they already pay state unemployment tax?

Like the state, the federal government also has an unemployment tax. It’s called FUTA and it’s an annual tax employers pay on the first $7,000 of each employee’s wages. The FUTA rate for 2022 is 6%, but most employers only have to pay 0.6% each year.Yes, employers pay both state and federal unemployment taxes.
