I agree with the previous poster. The fine print in the IRS guidelines do say that you need to have proper licenses. But, you don't always have to have one for "babysitting". I went to get one recently and they said I didn't need one. In fact, they said if I wanted to get licensed by the state, my city would make me go before the city planning during a monthly meeting and get permission.
I've done this for 26 years, never been audited and no one has ever asked me about licenses. Just make sure you count only what's reasonable and go to the website and download the publication that's about daycare from the IRS.
Malia, the standard business use of home rules don't apply in any way to daycare or preschool. That's why she needs to look up the space/time rules and how they apply.
