MyDOR Filing Services
Washington Department of Revenue filings made simple. B&O tax, use tax, and more - we handle your state tax obligations so you don't have to.
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.
