Massachusetts LLC Taxes & Fees 2026: Complete Cost Guide

Annual Report Fee (Ongoing Cost)

Massachusetts LLCs must file an Annual Report each year with the Secretary of the Commonwealth. The filing fee is $500, and the deadline is the anniversary date of your LLC's formation.

The Annual Report updates your business information on file with the state — including your principal office address, registered agent details, and the names and addresses of managers or members. Even if nothing has changed since your last filing, you must still file the report and pay the $500 fee.

If the Secretary of the Commonwealth doesn't receive your filing by the anniversary date, you'll face a $25 late fee plus $5 per month for each month the report remains overdue. While the late penalty itself is relatively modest compared to the filing fee, continued non-compliance can result in your LLC losing its good standing and eventually being administratively dissolved.

An administratively dissolved LLC cannot legally conduct business in Massachusetts. Reinstatement requires filing all overdue reports, paying all back fees and penalties, and submitting a reinstatement application — a process that can become expensive and time-consuming. Staying current with your annual report is far simpler and cheaper than dealing with dissolution.

Registered Agent Cost

Massachusetts requires every LLC to maintain a resident agent (Massachusetts's term for registered agent) with a physical Massachusetts address. The resident agent receives legal documents, service of process, and official state correspondence on behalf of your LLC.

If you hire a commercial registered agent service, typical pricing ranges from $100 to $300 per year. Given that Massachusetts already charges $500 for formation and $500 for the annual report, some LLC owners try to save money by serving as their own resident agent. This is allowed, but it means your personal address becomes part of the public record filed with the Secretary of the Commonwealth.

There are practical trade-offs to consider. Serving as your own agent means you must be available at the listed address during normal business hours to accept legal documents. If you miss a service of process delivery, it could result in a default judgment against your LLC. Many business owners find that the $100–$300 annual cost of a professional service is worthwhile for the privacy, reliability, and peace of mind it provides.

Massachusetts Taxes for LLCs

Massachusetts does not impose a traditional "franchise tax" on LLCs. However, your Massachusetts tax obligations depend on how your LLC is classified for federal tax purposes:

• Personal income tax (pass-through LLCs): Massachusetts imposes a flat 5% personal income tax on all taxable income, including a member's share of LLC income. Unlike states with graduated brackets, every dollar of income is taxed at the same rate.
• Annual excise tax (corporate-taxed LLCs): If your LLC elects to be taxed as a corporation, Massachusetts imposes a minimum annual excise of $456. If your LLC's net income results in a higher excise amount, you pay the higher figure instead. The excise tax rate is 8% of net income for most business corporations.
• Sales and use tax: If your LLC sells taxable goods or services in Massachusetts, you must collect and remit the state 6.25% sales tax. Certain items like clothing (up to $175 per item) and groceries are exempt.

Massachusetts does not impose a separate local or county income tax — the flat 5% state rate is the only income tax layer. This is a meaningful advantage compared to states like Maryland, where county income taxes add 2%–3% on top of the state rate. However, the combination of high formation fees, high annual report fees, and the potential $456 minimum excise still makes Massachusetts one of the more expensive states for LLC compliance overall.

Foreign LLC Registration Fee

If your LLC was formed in another state but you will be doing business in Massachusetts, you need to register as a foreign LLC with the Secretary of the Commonwealth. The filing fee is $500 — the same as domestic formation.

To register, you file a Foreign LLC Registration with the Corporations Division. You'll need to provide a certificate of good standing (or equivalent) from your home state, the name and address of your Massachusetts resident agent, and your LLC's principal office address.

After registration, you'll also be subject to the same $500 Annual Report requirement due on the anniversary of your foreign registration date, plus you'll need to maintain a Massachusetts resident agent. This means operating as a foreign LLC in Massachusetts is just as expensive as forming a domestic LLC in the state.

If you're considering forming in a low-cost state like Wyoming or Delaware and then registering as a foreign LLC in Massachusetts, run the numbers carefully. You'll pay formation fees in the other state plus $500 to register in Massachusetts, plus annual fees in both states. In most cases, unless you have a specific legal or structural reason, forming directly in Massachusetts is simpler and may not cost more overall.

Typical Total Cost (Year 1 vs Ongoing)

Massachusetts is undeniably one of the most expensive states for LLC formation and ongoing compliance. The $500 formation fee is among the highest in the nation, and the $500 annual report fee compounds that cost every year. By comparison, states like Colorado ($50 formation, $10 annual report) or Kentucky ($40 formation, $15 annual report) cost a fraction of what Massachusetts charges.

That said, if your business operates in Massachusetts, you likely need a Massachusetts LLC regardless of the cost. The state's strong economy, access to talent (particularly in the Boston metro area), and robust consumer market make it a valuable place to do business. Just make sure you budget for the higher-than-average state compliance costs from day one so there are no surprises.
