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
Underestimating Medicare/Medicaid billing complexity — hire an experienced home health biller from day one
- 2
Not understanding EVV compliance requirements — penalties for non-compliance are severe
- 3
Insufficient payroll capital — caregivers must be paid weekly even when insurers pay in 60-90 days
- 4
Not vetting caregiver staff thoroughly — one abuse or neglect incident can result in license revocation
- 5
Entering the market without building hospital and SNF discharge planner relationships first
