Washington State Taxes? Consider It Done.
B&O tax, use tax, quarterly filings—Uncle Sam speaks fluent DOR. You run your business. We'll handle Olympia.

What is MyDOR?
MyDOR (My Department of Revenue) is Washington State's online tax filing system. If you do business in Washington, you're likely required to file B&O tax returns and potentially other taxes through this system.
The Business & Occupation (B&O) tax is Washington's primary business tax. Unlike income tax, it's based on gross receipts - which means proper classification and deductions are crucial to avoid overpaying.
Did You Know?
Washington has no income tax, but B&O tax applies to almost all businesses. Even out-of-state businesses with WA customers may have filing requirements.
Quarterly Filing Deadlines
Monthly filers have different deadlines. Annual filers are due January 31.
