Washington Unemployment Insurance Tax: $78,200 Wage Base in 2026, New Employer Rate and Shared-Cost Surcharge
Washington Unemployment Insurance Tax: $78,200 Wage Base in 2026, New Employer Rate and Shared-Cost Surcharge
If you have employees in Washington, you pay the Washington unemployment insurance tax on a capped slice of each worker's wages. For 2026, that cap, called the taxable wage base, is $78,200. It was $72,800 in 2025 and rises to $82,000 in 2027. Your actual rate depends on your own claims history, whether you are a new employer, and a flat shared-cost tax that applies on top. This guide walks through each piece so you can budget payroll and avoid surprises when your rate notice arrives.

What the $78,200 wage base means
The wage base is the maximum amount of each employee's wages in a calendar year that is subject to unemployment insurance (UI) tax. Wages above the base are not taxed for UI that year. The base changes from year to year:
| Year | Taxable wage base |
|---|---|
| 2025 | $72,800 |
| 2026 | $78,200 |
| 2027 | $82,000 |
Here is how that plays out. An employee paid $50,000 in 2026 has all $50,000 taxed. An employee paid $95,000 has only the first $78,200 taxed, and the remaining $16,800 is not subject to UI tax. The base applies to each employee separately, not to your total payroll, so track each worker's year-to-date wages from the first pay period of the year.
How your UI tax rate is built
Washington does not use one flat UI rate. Your rate is assembled from three parts:
- Experience rate: based on your own unemployment claims history, capped at 5.4%.
- Shared-cost (social) tax: a flat rate, capped at 1.22%.
- Employment Administration Fund fee: between 0.02% and 0.03%.
Your experience rate plus your shared-cost tax generally cannot exceed 6%. RCW 50.29.025 sets a different limit for certain agriculture and food-processing industries, so if your business falls into one of those, confirm your ceiling with ESD before you budget.
Under the general 6% ceiling, the most a standard employer would pay on one worker's 2026 wages is $4,692 (6% of $78,200), plus the Employment Administration Fund fee. That figure is a ceiling, not a typical bill. Your actual rate is set by ESD for your account.
Your experience rate and the 40 rate classes
ESD places each employer into one of 40 rate classes. Placement is based on the unemployment benefits charged to your account over a four-year look-back period. When former employees collect benefits charged to your account, your experience generally moves toward a higher class. An account with few charges generally moves toward a lower one.
Your rate applies to the next calendar year. ESD mails rate notices each December, so the notice you receive in December 2026 sets your rate for 2027. Read it when it arrives and compare the figures against your payroll budget.
For example, if ESD assigned you a 2.0% experience rate, you would owe $1,564 on a $78,200 wage (2% of $78,200) before the shared-cost tax and the Employment Administration Fund fee. The 2.0% figure is an illustration only, not a published Washington rate.
New employer rate
If your business has no Washington unemployment claims history, ESD treats it as a new employer. For 2026, new employers pay 115% of their industry's average rate. New employer status generally lasts 2.5 to 3 years, after which your own experience determines your rate. Confirm the exact period that applies to you with ESD.
As an illustration only, if your industry's average rate were 1.5%, a new employer would pay 1.725% (1.5% multiplied by 115%). Ask ESD for the industry average that applies to your business and check it against your rate notice.
The shared-cost surcharge explained
The shared-cost tax is the social tax portion of your UI bill. It is a flat rate capped at 1.22%, and it is added to your experience rate, not substituted for it. This is the surcharge in the title, and it is easy to overlook when you estimate costs from the experience rate alone.
Despite the name, employees do not pay any part of Washington UI tax. The employer bears the full cost of the experience rate, the shared-cost tax and the Employment Administration Fund fee.
Delinquency add-ons
Delinquent employers face add-ons of 0.5%, 1.0%, 1.5% or 2.0%. These add-ons are the cost of falling behind, so the simplest way to avoid them is to keep every report and payment on schedule. ESD sets the conditions that trigger each add-on and how long it lasts. Confirm those details with ESD before you assume your rate is final.
Weekly benefit amounts
For claims opened on or after July 5, 2026, the weekly benefit amount ranges from a minimum of $383 to a maximum of $1,208. Benefits charged to your account are what feed your experience rate, so the benefit schedule affects your costs over time, even though you do not set it.
Washington UI tax compared with B&O tax
Do not confuse UI tax with the business and occupation (B&O) tax. Washington has no corporate income tax and no personal income tax on wages. Instead, most businesses pay the state B&O tax, a gross receipts tax with more than 50 activity classifications and no deduction for labor, materials or other costs. About 54 cities also levy their own B&O tax, which the Department of Revenue does not administer. UI tax is a separate payroll cost based on wages, not revenue.
Common budgeting mistakes
- Applying the $78,200 base to your total annual payroll instead of to each employee's wages.
- Estimating costs from the experience rate and leaving out the shared-cost tax and the Employment Administration Fund fee.
- Assuming the new employer rate lasts indefinitely instead of planning for the move to an experience rate.
- Deducting UI tax from employee paychecks. Employees do not pay UI tax in Washington.
Steps to take now
- Check whether you need a state business license. The Business License Application through the Department of Revenue's Business Licensing Service is required if you plan to hire employees within 90 days. The application also issues your 9-digit Unified Business Identifier (UBI).
- Set up your employer account with ESD before your first payroll, and confirm the setup steps on the ESD website.
- Track each employee's year-to-date wages against the $78,200 base for 2026.
- Budget at the new employer rate of 115% of your industry average, plus the shared-cost tax and the Employment Administration Fund fee, for as long as you remain a new employer.
- Read your December rate notice carefully. It sets the rate for the next calendar year.
- File reports and make payments on time to avoid delinquency add-ons.
