Current year's total payroll expense of less than $100 million Current year's total payroll expense of $100 million or more, but less than $1 billion Current year's total payroll expense of $1 billion or greater
Total annual payroll expense for employees who have annual compensation of $150,000 to $399,999.99 in the current year Rate = 0.7% Rate = 0.7% Rate = 1.4%
Total annual payroll expense for employees who have annual compensation of $400,000 or more in the current year Rate = 1.7% Rate = 1.9% Rate = 2.4%

This tax is paid to the City of Seattle and will require that businesses have an account with this agency. You'll need to provide the following information in the Tax Settings of your Payroll app in Zenefits.
