How to start a pet sitting business in Massachusetts
Pet sitting and dog walking need no degree or state exam, but a few registrations come up in every state. Here is what Massachusetts's own agencies say, checked October 7, 2026. Rules change, so follow each link before you file.
1. Register the business
LLCs file a Certificate of Organization with the Secretary of the Commonwealth's Corporations Division. A business using a name other than its legal name, including a sole proprietor not using their own name, files a business certificate (DBA) with the clerk of the city or town where the business is located.

2. Sales tax on pet sitting
Not confirmed: ask the state
We could not find a Massachusetts Department of Revenue statement on pet sitting or boarding. Check with the Department of Revenue before you start.

3. Licenses for boarding and pet care
Massachusetts law treats any establishment that boards, holds or provides day care, overnight stays or training for other people's animals for pay as a commercial boarding or training kennel. The only exception for individuals is someone who boards or cares for animals temporarily and not in the normal course of business. Kennel licenses come from your city or town clerk (in Boston, the police commissioner), so check with them before boarding dogs in your home.
