How to start a pet sitting business in Illinois
Pet sitting and dog walking need no degree or state exam, but a few registrations come up in every state. Here is what Illinois's own agencies say, checked October 7, 2026. Rules change, so follow each link before you file.
1. Register the business
An LLC files with the Illinois Secretary of State. A sole proprietor using a name other than their full legal name registers it with the county clerk under the Assumed Name Act.

2. Sales tax on pet sitting
Not taxable
The Department of Revenue says Illinois doesn't tax sales of services, only items transferred as part of one, and we found no rule singling out pet care. Food or supplies you hand over as part of the service can be taxable, so check with the department if you do.

3. Licenses for boarding and pet care
The Illinois Department of Agriculture licenses kennel operators and day care operators under the Animal Welfare Act. A kennel operator keeps dogs, or dogs and cats, for boarding for a fee. We found no in-home exemption, so check with the department before boarding.
