Licenses & Permits in Washington
General Business License
Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Common Mistakes to Avoid
- 1
Working without a state pesticide applicator license — it's illegal and results in fines and business closure
- 2
Not building recurring service contracts — one-time treatments are less valuable than quarterly service agreements
- 3
Underestimating the value of a pest control route — a recurring route of 200 customers at $100/quarter = $80,000/year of predictable revenue
- 4
Not investing in termite treatment capability — termite inspections and treatments are high-margin work
- 5
Skipping pollution liability insurance — a pesticide misapplication claim can exceed your general liability limits
