If you run a business in Washington, you’ll want to know these fun facts about paying and filing payroll taxes in Washington.

Operating a business in Washington: here’s what you need to know about payroll tax

Business owners in Washington should understand that Washington is a no personal income tax state. It joins the ranks of these other states that do not have a state income tax: Nevada, Wyoming, South Dakota, Texas, Florida, Alaska, and Tennessee.

Though there is no personal income tax in Washington, you’ll need to pay and withhold federal payroll taxes and pay state unemployment tax.

Washington unemployment tax

To help workers who have lost their jobs through no fault of their own, Washington employers must pay unemployment tax.  For 2022, the first $62,500 of each employee’s wage is taxed for unemployment. Rates vary based on industry and the history of claims paid to former workers. 

Federal payroll taxes

There are four key federal payroll taxes, described below.

Federal income tax

Employers must withhold federal income tax (FIT) from their employees’ paychecks unless the employee is exempt. 

This tax is paid only by employees, and you can determine how much to withhold by obtaining a Form W-4 from each employee. This will provide the employee’s number of dependents, filing status, and other variables, which—along with their wage information—will allow you to determine the appropriate withholding amount.Fortunately, payroll software makes these calculations easy. When you add an employee and input their information, the software automatically calculates the tax amount to be withheld.


Federal Insurance Contributions Act (FICA) 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.

Additional Medicare tax

Certain employees who earn more than $200,000 in a year will be subject to the Additional Medicare tax. For 2022, you’ll withhold 0.9% of any wages above $200,000. 

This tax must be withheld, but the individual employee may not be required to pay this. It will be their responsibility to determine this when they file their tax return.

FUTA tax

Like the state, the federal government also has an unemployment tax. It’s called FUTA, Federal Unemployment Tax Act, 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 many employers only have to pay 0.6% each year.
