The most important issues you should ask about are background checks, workman’s compensation, business licenses, and insurance. If you end up hiring an independent cleaner who doesn’t have those things, you are at risk of the IRS viewing you as their employer in the event any on-the-job injuries occur at your house. These types of injuries can result in you being liable for employer payroll taxes, workman’s compensation, medical payments, and house repairs for any damage to your property and home.
