Washington state doesn’t have income tax like most states, but business owners do need to pay Business and Occupation (B&O) tax, and this is usually on a state and city level. Here’s what the B&O tax looks like for your business.
Washington State
B&O tax is based on the gross income from business activities. This means there are very limited deductions for business-related expenses.
2024 Washington State B&O Tax Classifications
To find out your tax rate, you’ll first need to determine your business classification. The Department of Revenue groups businesses into tax classifications based on common business activities. Some businesses may fall into multiple classes. The major classifications and tax rates are:
Retailing: 0.471%
Wholesaling: 0.484%
Manufacturing: 0.484%
Service and Other Activities: 1.5%
If you’re unsure how your business is classified, the Department of Revenue provides a list of common business activities and their corresponding tax classification(s).
Starting April 1, 2020, an additional B&O tax was implemented for those under the Service and Other Activities classification. This additional tax, created to fund workforce education, is known as the Workforce Education Surcharge. There are two tax rates for this surcharge on your tax returns:
Service and Other Activities ($1 million or greater in the prior year): 1.75% tax rate
Service and Other Activities: 1.5% tax rate
B&O Due Dates
Once you’ve registered your business with the Department of Revenue, they will provide information about filing deadlines. You may need to file monthly, quarterly, or annually depending on the projected gross receipts of your business. The due dates for each are:
Monthly: The 25th of the following month
Quarterly: The end of the month following the close of the quarter
Annually: April 15th
If a due date falls on a weekend or holiday, returns are due the next business day.
Credits
The Department of Revenue offers credits to certain businesses, including a Small Business B&O Tax Credit. There are two credits available under the Small Business Tax Credit depending on your taxable income and total B&O tax liability.
The Small Business Tax Credit [720] applies if:
50% or more of your taxable income was reported under Service and Other Activities, Gambling Contests of Chance, For-Profit Hospitals, and/or Scientific R&D and
Your B&O tax liability is under:
$141 for monthly taxpayers
$421 for quarterly taxpayers
$1,681 for annual taxpayers
The Small Business Tax Credit [815] applies if:
Less than 50% of your taxable income was reported under Service and Other Activities, Gambling Contests of Chance, For-Profit Hospitals, and/or Scientific R&D and
Your B&O tax liability is under:
$71 for monthly taxpayers
$211 for quarterly taxpayers
$841 for annual taxpayers
If you qualify, the Department of Revenue provides worksheets to figure out how much your Small Business Tax Credit will be for monthly, quarterly, and annual taxpayers.
