Forming a Massachusetts LLC in 2026: Costs, Filings, Annual Duties

Filing to form a Massachusetts LLC online

An LLC is still the most popular structure for new Massachusetts businesses. It’s flexible and quick to set up, and it separates business debts from your personal assets. Here’s what forming one involves today.

Step 1: Pick a name and a resident agent

Your LLC’s name must be distinguishable from other entities on file with the Secretary of the Commonwealth, and it must include “LLC” or similar. Every Massachusetts LLC also needs a resident agent with a Massachusetts address to receive legal papers.

Step 2: File a Certificate of Organization

You file online with the Corporations Division. The filing fee is $500. The certificate names the LLC, its address, its business purpose, its resident agent, and at least one manager or person authorized to sign documents.

Step 3: Get an EIN and open a business bank account

Apply for a free Employer Identification Number from the IRS. Use it to open a bank account in the LLC’s name. Keeping business money separate is one of the most important ways to preserve your liability protection.

Step 4: Put an operating agreement in writing

Massachusetts doesn’t require one, but an operating agreement is where the real protection lives. It covers who owns what, who makes decisions, how profits are split, and what happens if a member leaves or dies.

Step 5: Register for taxes and licenses

Register with the Massachusetts DOR through MassTaxConnect if you’ll collect sales tax or have employees. Check your city or town for any local licenses. If the LLC will operate under a name other than its registered name, file a business certificate (DBA) with the city or town clerk.

Every year after that

The tax information above is general information, not tax advice. Talk with an accountant or tax advisor about how your LLC should be taxed.

One filing you can skip: FinCEN now exempts companies formed in the U.S. from federal beneficial ownership (BOI) reporting.

Is an LLC right for you?
