How to start a pet sitting business in New Hampshire

Pet sitting and dog walking need no degree or state exam, but a few registrations come up in every state. Here is what New Hampshire's own agencies say, checked October 7, 2026. Rules change, so follow each link before you file.

1. Register the business

A sole proprietor doing business under any name other than their own legal name must register it as a trade name with the Secretary of State (Form TN-1, $50), renewed every five years. LLCs are formed with the Secretary of State.

2. Sales tax on pet sitting

Not taxable

New Hampshire has no general sales tax. Its 8.5% Meals and Rentals Tax covers meals, rooms, and motor vehicle rentals.

3. Licenses for boarding and pet care

The state's Pet Vendor License is for people who transfer animals (for example 30 or more dogs a year), not for boarding. We found no statewide license for pet sitting. Check with your town for local rules.
