Washington · Sales tax registration
Washington business licence and sales tax registration.
Washington bundles this differently from every other state. The Business Licensing Service application with the Department of Revenue covers your licence and the excise tax account, which carries both retail sales tax and Business and Occupation tax, and it is also what opens your employer accounts if you are hiring.
Who you are dealing with
Washington Department of Revenue
- Handles:
- Business licence, retail sales tax, and Business and Occupation tax, reported together on the combined excise tax return
- System:
- Business Licensing Service, then My DOR
- Form:
- The Business Licensing Service application. Revenue shares what you submit with Employment Security and Labor and Industries where applicable
State fee. Washington charges a business licence fee through the Business Licensing Service. We pass it through at cost and show it as a separate line before you pay.
When you have to register
Register before making taxable retail sales in Washington. There is no state income tax, so there is no withholding account, but there is a Business and Occupation tax on gross receipts that has no equivalent in most states.
What comes next
Not applicable to a registration. Washington behaves the same way on the way out: Revenue shares your closure with Business Licensing, Employment Security, and Labor and Industries, and the final excise return is due with payment by the 25th of the following month.
How long it takes
Washington does not publish a turnaround we could confirm. The sequencing is what matters: the Business Licensing Service application is the entry point, and the other accounts follow from it.
What we do
We work out exactly which accounts you need, prepare and submit each registration, and hand you the account numbers, rates, and deposit schedules your payroll system asks for. One flat price per account, and any state fee passed through at cost.
What makes Washington harder than average
- Business and Occupation tax surprises people. Washington taxes gross receipts as well as retail sales, and both are reported on the same combined excise tax return. A business budgeting only for sales tax has missed half the picture.
- The licence carries a fee where most sales permits do not. It is a licence rather than a permit, and it is priced accordingly.
- Revenue is the hub, so start there. Applying directly to Employment Security or Labor and Industries first does not begin the chain. The Business Licensing Service application is the entry point in both directions.
- Records for five years. Washington asks businesses to keep records for five years after closing, which is longer than most people plan for.
Questions and answers
What is Business and Occupation tax?
A Washington tax on gross receipts, reported on the same combined excise tax return as retail sales tax. Most states have nothing equivalent, so it is the item most often left out of a Washington budget.
Is there a fee?
Yes. Washington charges a business licence fee through the Business Licensing Service, which we pass through at cost and show separately.
Do I need a separate registration if I hire?
Generally not for the notification itself. Revenue shares what you submit with Employment Security and Labor and Industries where applicable, which is unusual and genuinely helpful. You still owe those agencies their own filings.
Is there a withholding account?
No. Washington has no state income tax on wages, so there is no withholding registration. Payroll here means unemployment insurance, paid leave, and workers' compensation.
What do you need from me to start?
The legal name and FEIN, entity type, Washington locations, what you sell, the date taxable sales begin, and whether you will have employees and what work they will do, since that affects the Labor and Industries classification.
