Determining your tax rates
Washington's unemployment-insurance program is an experience-based system. In general, your tax rate depends on how much your former workers collect in unemployment benefits and the size of your payroll.
There are two major components of state unemployment taxes, an experience-rating tax based on an average of the employer's layoff history over the past four fiscal years and a shared-cost (social) tax based on costs from the previous year that can't be attributed to a specific employer.
Employers with delinquent tax bills also may receive a range of delinquent-tax rates. The lowest delinquent-tax rate for experienced employers in 2021 is 1.13 percent, and the highest is 8.03 percent.

Calculate your tax rate
You can use our online calculators to figure out your tax rate. Use this calculator (.xls) if you have your taxable wages and benefit charges for the last four years.
If you are a new employer or haven't been in business long enough, you won't have enough "experience" to get your own tax rate. Instead, you will be assigned a rate based on your industry. For 2021, new employers will pay 115 percent of the average rate for all businesses in their respective industries, with the minimum rate being 1.00% as set by federal law.
You must send all past-due taxes and/or late reports to us by September 30 to avoid a delinquent tax rate for the following year.
If you owe taxes and cannot make full payment, contact the collections unit by emailing firstname.lastname@example.org for setting up a payment plan. If your payment plan is approved before September 30, you will receive your earned tax rate for the following year, rather than the delinquent rate.
