Cost of hiring an employee in Washington

Washington has the highest unemployment wage base of these ten states by a wide margin, and it charges workers compensation by the hour rather than as a share of payroll.

What makes Washington distinctive

The number that changes the arithmetic in Washington is the taxable wage base of 78,200 dollars. In most states the unemployment tax stops after the first few thousand dollars of wages, so it is a rounding error. In Washington almost the entire salary of a typical hire is taxable, which turns state unemployment from a footnote into a real line item.

New employer rates are set by industry rather than by a single statewide figure, so two employers opening in the same month can face very different rates depending on the claims history of their sector. Construction and seasonal industries open high.

Washington also runs a paid family and medical leave program funded by a premium split between employer and employee, and it charges workers compensation through a state fund on an hours worked basis rather than per 100 dollars of payroll. That hourly structure means a low paid role and a high paid role in the same class code cost the same in premium, which quietly penalises labour intensive, lower wage staffing.

The employer cost breakdown in Washington

Employer FICA, 7.65 percent

Social Security at 6.2 percent up to the annual wage cap and Medicare at 1.45 percent with no cap. This is identical in every state and is the largest single statutory line for most employers.

Federal unemployment tax

Federal unemployment tax runs at the standard 0.6 percent effective rate on the first 7,000 dollars, about 42 dollars per employee per year.

Washington unemployment insurance

New employer rate: varies by industry for new employers, commonly in the 1 to 3 percent range. Taxable wage base: 78,200 dollars per employee per year. That works out at about 700 to 2,100 dollars per employee at a 70,000 dollar salary.Experienced employers are given an individual rate based on their own claims history, which can be lower or higher than the new employer figure.

The wage base is the highest in this cluster, so most of a typical salary is subject to state unemployment tax.
New employer rates are assigned by industry, not by a single statewide default.
Paid family and medical leave premiums are shared between employer and employee.
Workers compensation is charged per hour worked through the state fund, so it scales with hours rather than with wages.

Workers compensation

Because premiums are per hour, a full time worker in a heavy class code can cost well over a thousand dollars a year regardless of salary. Part time and seasonal patterns change the total more than pay level does.

Benefits and overhead

Seattle metro salaries and medical premiums both sit above the national picture, and several local ordinances add compliance overhead that smaller employers underestimate.Medical, dental, vision, life, disability and any retirement match usually dwarf the tax lines. Add equipment, software seats and a share of space or remote stipend on top.

Worked example: a 70,000 dollar salary in Washington

Total employer cost lands somewhere in the region of 89,000 dollars to 113,000 dollars a year. The range is wide because benefits design and workers compensation class code move the total far more than any tax rate does.

Base salary	70,000 dollars
Employer FICA at 7.65 percent	about 5,355 dollars
Federal unemployment	about 42 dollars
State unemployment on the full salary	about 700 to 2,100 dollars
Paid family and medical leave, employer share	about 150 to 400 dollars
Workers compensation, hourly	about 250 to 2,000 dollars
Benefits and retirement	about 9,000 to 21,000 dollars
Equipment, software and overhead	about 3,000 to 12,000 dollars
Estimated total employer cost	89,000 dollars to 113,000 dollars

Washington is the clearest case in this cluster where state unemployment tax is worth modelling properly rather than treating as noise.
