Washington requirements for this business

  • You need a Washington business license if, among other triggers, your gross income is $12,000 per year or more, you use a name other than your legal name, or you plan to hire employees within 90 days. [source]
  • Janitorial services regularly performed by commercial janitorial businesses are taxed under service and other activities B&O tax and are not subject to retail sales tax. [source]
  • Specialized or non-repetitive cleaning, such as mold abatement, duct cleaning, fire damage cleanup, hoarder cleanup, and exterior building cleaning, is a retail sale subject to sales tax. [source]
  • DOR's janitorial rule is framed around commercial janitor service businesses and does not specifically address residential cleaning, so home cleaners may want to confirm their classification with DOR. [source]
