How to start a pet sitting business in Massachusetts (2026)

1Pet sitting demand in Massachusetts

About 49% of Massachusetts households own at least one pet. Greater Boston's hospitals, universities and biotech firms employ many people with long shifts and conference travel, which drives both drop-ins and overnights. Cats are a big share of the work in Boston, Cambridge and Somerville apartments where dogs are restricted. Summer weekends on Cape Cod, Martha's Vineyard and Nantucket, plus the February and April school vacation weeks, empty the suburbs at the same time, so Newton, Wellesley and the North Shore book up together. Second-home owners on the Cape and in the Berkshires add more sits.

The biggest markets: Boston, Cambridge / Somerville, Newton / MetroWest, Worcester.

2Can you board pets at home in Massachusetts?

Massachusetts draws a clear line. Visiting or staying overnight in the client's home does not need a kennel license, according to the Department of Agricultural Resources, though local bylaws can add rules. Boarding dogs at your own home for pay while the owner is away makes you a commercial boarding kennel under state law (MGL c.140, s.136A), with no minimum number of dogs. The only home exclusion is for someone who watches animals temporarily and not in the normal course of business. Under Ollie's Law (2024), you license with your city or town clerk, the animal control officer inspects first, and every boarded dog needs a current municipal dog license. Zoning still applies, and many towns restrict kennels in residential districts.

3Set up your business in Massachusetts

• File an LLC. $500 one-time filing with the Massachusetts Secretary of the Commonwealth (Corporations Division). It separates your personal assets from the business, which matters when you hold clients' keys.
• Recurring entity cost: $500/year, annual report filed with the Secretary of the Commonwealth by the anniversary of your original filing.
• Get an EIN from the IRS. It is free and takes about 10 minutes online.
• City or county business license: Massachusetts cities and towns generally don't sell a general business license. If you operate under any name other than your own legal name (or your LLC's legal name), you file a business certificate (DBA) with the city or town clerk where the business is located, with fees set locally. Pet sitting in clients' homes and dog walking do not need a kennel license, but check your town's bylaws.

Massachusetts-specific: Massachusetts charges $500 to form an LLC and another $500 for every annual report, so the entity costs about $500 a year for as long as it exists. That is among the highest ongoing LLC costs in the country. A lot of solo walkers start as a sole proprietor with a business certificate from their town clerk and good insurance, then form the LLC once revenue makes the $500 a year easy to absorb.

4Taxes for Massachusetts pet sitters

Sales tax: Massachusetts sales tax (6.25%) applies to tangible goods and telecom services, and the Department of Revenue lists personal and professional services as generally exempt. Dog walking, drop-ins and pet sitting are services, so no sales tax is charged on them. If you sell products (treats, leashes, branded gear), those are taxable, must be itemized separately, and require registering with MassTaxConnect. The DOR has no published ruling on pet care by name, so if you add something unusual (selling food, retail at a boarding space), check with the DOR Rulings and Regulations Bureau.

State income tax: Flat-rate state income tax.

Other taxes worth knowing: Massachusetts taxes income at a flat 5%, plus a 4% surtax only on income above $1,107,750 (2026 threshold), which almost no dog walking business will reach. If you hire, you also withhold Paid Family and Medical Leave contributions: 0.88% of wages in 2026, and businesses with fewer than 25 workers send 0.46%, all of which can come out of the worker's pay.

5Insurance and bonding in Massachusetts

Overnight sitting here means winter risks: a nor'easter can cut power, freeze pipes or leave you snowed in at a client's house. Ask your carrier how the policy handles damage to the client's home while it is in your care, and confirm lost-key coverage, since many Boston clients hand over building fobs as well as keys. Get each client's heating contractor and snow plan in writing. A bond protects clients against employee theft once you hire, and workers' comp is required from your first employee.

• General liability with care, custody and control covers harm to the pets in your care and damage in the client's home.
• Key and lockout coverage pays to rekey a home if you lose a client's key.
• A bond covers theft claims and is a cheap way to reassure new clients.

Workers' comp once you hire: Massachusetts requires workers' compensation for every employer, no matter how many employees, including a single part-time sitter. Solo owners with no employees don't need it. The Department of Industrial Accidents issues stop work orders to uninsured employers, with fines starting at $100 per day (weekends included) until coverage is in place.

6What to charge in Massachusetts

Typical Massachusetts bands for 2026:

• Drop-in visit (30 min): $22 to $38
• Overnight in the client's home: $80 to $130 per night
• Additional pet: +$5-10 per visit

Overnights and peak dates: Massachusetts overnights run about $80-130 a night, with Greater Boston at the top. Peak dates are Thanksgiving, the Christmas and New Year break, the February and April school vacation weeks, and summer weekends when families head to the Cape and islands. Open holiday booking early and add a holiday surcharge. Snow can slow travel between client homes, so line up backup coverage before winter.

7Hiring sitters in Massachusetts

Massachusetts has one of the strictest classification tests in the country (MGL c.149, s.148B). A worker is an employee unless you prove all three prongs: they are free from your control, the work is outside the usual course of your business, and they run their own independent business doing the same work. A sitter walking dogs for a dog walking company fails the second prong almost by definition, so plan on W-2 from your first hire.

Misclassification in Massachusetts is expensive because the burden is on you. If you can't prove all three prongs of the ABC test, the sitter is an employee, and Massachusetts law gives workers triple damages for unpaid wages and benefits plus attorneys' fees. Add back workers' comp exposure and a possible stop work order, and one unhappy former sitter can cost far more than a year of payroll taxes.
