How to Start a House Cleaning Business in Illinois

Residential cleaning is one of the lowest-barrier service businesses: supplies and a reliable vehicle are the main costs. Trust is the product, so insurance, bonding and consistent quality matter more than equipment.

Illinois requirements for this business

  • Illinois does not tax the service itself; under the Service Occupation Tax, only tangible personal property transferred as part of a sale of service is taxable. [source]
  • Servicepersons with a physical presence in Illinois generally must register with IDOR and collect Service Occupation Tax, but a de minimis serviceperson (property transferred is under 35% of receipts, typical for house cleaning) may instead pay Use Tax to its suppliers and not register. [source]
  • Illinois says an employer with one employee, even a part-time employee, must obtain workers' compensation insurance; fines can reach $500 per day of noncompliance, with a minimum fine of $10,000. [source]
  • A sole proprietor doing business under a name other than the owner's real name files an Assumed Name Certificate with the county clerk, and the notice must be published once a week for three consecutive weeks. [source]

Statewide steps for every Illinois business — forming an LLC or registering a business name with the State of Illinois — are on our state licensing directory.

Licenses and registration

  • Get a free Employer Identification Number (EIN) from the IRS if you will hire employees or form an LLC or corporation. Beware of sites that charge for this. [source]
  • Register an LLC or corporation with your state's business registration office (sole proprietors usually register a trade name/DBA instead). [source]

Insurance to consider

  • General liability (accidental damage in client homes)
  • Janitorial bond (theft protection clients often ask about)
