How to Start an LLC in Massachusetts (6 Steps)

Step 1: Name Your Massachusetts LLC

Your Massachusetts LLC name must be distinguishable from any other business entity on file with the Secretary of the Commonwealth. The name must include a designator such as “Limited Liability Company,” “LLC,” “L.L.C.,” or similar abbreviation. You can search for available names using the Massachusetts business entity search.

If you find an available name and aren’t ready to file immediately, you can reserve it for 60 days by filing a Name Reservation with the Secretary of the Commonwealth for $30. This prevents anyone else from registering the same name while you prepare your formation documents.

Before finalizing your name, check whether the matching domain name is available for your website and whether the name is available on social media platforms. You should also search the USPTO trademark database to make sure your desired name doesn’t infringe on an existing trademark.

Massachusetts naming rules:

• Must include “Limited Liability Company,” “LLC,” “L.L.C.,” or similar abbreviation
• Must be distinguishable from other business names on file with the Secretary of the Commonwealth
• Cannot include words that imply the LLC is a bank, insurance company, or government agency without proper licensing
• Cannot contain language suggesting a purpose the LLC is not authorized to pursue

Step 2: Choose a Resident Agent

Massachusetts requires every LLC to have a resident agent (Massachusetts uses the term “resident agent”) with a physical street address in Massachusetts. The resident agent receives legal documents — including lawsuits, subpoenas, and official state correspondence — on behalf of your LLC. This is a legal requirement, and your LLC cannot be formed without designating a resident agent.

You can serve as your own resident agent (if you have a Massachusetts address), appoint a trusted friend or family member, or hire a professional registered agent service. While acting as your own resident agent saves money, it means your personal address becomes public record and you must be available at that address during all normal business hours to accept documents.

Our top recommendation is Northwest Registered Agent ($39/year), which also handles LLC formation for $39 + the $500 state fee. Using a professional service provides privacy, ensures you never miss an important document, and frees you from having to be physically present at a fixed address during business hours.

Step 3: File Your Certificate of Organization

To officially create your Massachusetts LLC, you need to file a Certificate of Organization with the Secretary of the Commonwealth. The fastest way to file is online through the Massachusetts Corporations Division. You can also file by mail, but online filing is recommended for faster processing.

When completing the Certificate of Organization, you’ll need to choose between a member-managed and manager-managed structure. In a member-managed LLC, all owners participate in running the business. In a manager-managed LLC, one or more designated managers handle day-to-day operations while other members are passive investors. Most small LLCs choose member-managed.

Filing details:

• Filing fee: $500
• Online filing: Massachusetts Corporations Division (recommended)
• Processing time: 5-7 business days (standard)

Information required:

• LLC name
• Principal office address
• General character of business (purpose)
• Resident agent name and address
• Manager or member names and addresses
• Effective date (can be a future date)
• Fiscal year end date

Step 4: Create an Operating Agreement

Massachusetts does not legally require an operating agreement, but having one is strongly recommended for every LLC, whether single-member or multi-member. An operating agreement is an internal document that establishes the rules for how your LLC is run, including ownership percentages, profit and loss distribution, voting rights, and what happens if a member wants to leave or if the LLC is dissolved.

Without an operating agreement, your LLC will be governed by the default rules in the Massachusetts Limited Liability Company Act, which may not align with your intentions. For example, the default rules assume profits are split equally among members regardless of their capital contributions. An operating agreement lets you customize these terms. Most banks and financial institutions also require a copy of your operating agreement before they will open a business bank account.

Step 5: Get an EIN

Apply for an Employer Identification Number (EIN) through the IRS website. It’s free and takes about 15 minutes online. An EIN is a nine-digit number assigned by the IRS that acts as your LLC’s tax identification number — think of it as a Social Security Number for your business. You need an EIN to open a business bank account, hire employees, file federal taxes, and apply for business permits. Even single-member LLCs with no employees should get an EIN, as it helps keep your personal Social Security Number off business documents.

Step 6: File Your Massachusetts Annual Report

All Massachusetts LLCs must file an annual report with the Secretary of the Commonwealth. The filing fee is $500, making it one of the most expensive annual report requirements in the country. The annual report is due on the anniversary date of your LLC’s formation. For example, if you formed your LLC on June 15, your annual report is due by June 15 each year.

File your annual report through the Massachusetts Corporations Division online portal. Failure to file can result in your LLC being revoked by the state. Massachusetts also requires LLCs to file state income tax returns, as the state imposes a flat 5% income tax on income passed through to members.

Massachusetts LLC Costs

Total first-year cost: $1,000-$1,300. This range covers the required state filing fee ($500) plus the annual report ($500) and an optional resident agent service. If you serve as your own resident agent, your mandatory costs are $1,000 in the first year. Massachusetts is one of the most expensive states for LLC formation and maintenance. See our complete guide to LLC costs by state.

Massachusetts LLC Taxes

Massachusetts has a flat 5% state income tax rate, which applies to LLC profits passed through to members. This flat rate applies to all income levels, making tax calculations straightforward. LLCs are treated as pass-through entities for tax purposes, meaning the LLC itself does not pay state income tax — instead, profits flow through to the members’ personal tax returns.

Massachusetts does not impose a separate franchise tax on LLCs, though the $500 annual report fee effectively functions as an annual business tax. Multi-member LLCs taxed as partnerships must file a Massachusetts partnership return (Form 3) with the Department of Revenue.

Massachusetts has a state sales tax rate of 6.25% with no additional local sales taxes. If your LLC sells taxable goods or services, you’ll need to collect and remit sales tax. Clothing items under $175 are exempt from sales tax. You can register for a sales tax license through the Massachusetts Department of Revenue.

Remember that all LLC members still owe federal income tax and self-employment tax (15.3%) on their share of LLC profits, regardless of the state’s tax treatment. Massachusetts also taxes short-term capital gains at 8.5% and long-term capital gains at 5%.

Massachusetts LLC Annual Requirements

Every Massachusetts LLC must file an annual report with the Secretary of the Commonwealth on the anniversary of the LLC’s formation date. The filing fee is $500. This report updates the state on your LLC’s current information, including your resident agent, principal office address, and management details. File online through the Corporations Division for the fastest processing.

In addition to the annual report, you should keep your resident agent information current and file an amendment if your LLC’s name, resident agent, or other key information changes. Maintain accurate internal records, including your operating agreement, meeting minutes, and financial statements. Massachusetts LLCs must also file state income tax returns and comply with any local business license requirements.

If you want to confirm that your LLC is in good standing, you can request a Certificate of Good Standing from the Secretary of the Commonwealth for $15. This document is sometimes needed when applying for business loans, opening bank accounts in other states, or registering your LLC as a foreign entity in another state.
