Massachusetts at a glance
What makes Massachusetts different
- The MA LLC vs Corp cost asymmetry is the single biggest customer surprise. LLC formation $500 + LLC Annual Report $500 = $1,000/year recurring. Profit Corp formation $275 + Corp Annual Report $125 = $400/year recurring. A Massachusetts LLC costs 2.5x…
- All checks payable to "Commonwealth of Massachusetts" (not "Secretary of State" or "Corporations Division"). Common rejection cause.
- Corp annual report has tiered late penalty: $125 timely, $150 if late, $100 if filed electronically (and timely). Customers get a $25 discount for filing electronically + on time. LLCs and LPs DO NOT get an electronic discount on Annual Report ($500 either way).…
- Corp formation fee is tiered by authorized shares. $275 minimum (up to 275,000 shares), +$100 per additional 100,000 shares. Wizard must prompt for authorized share count and compute.
- Foreign Corp registration is $400 (not $275). Higher than domestic Corp formation. LLC foreign registration is same as domestic ($500).
- Massachusetts has a corporate excise tax (8% on net income + $2.60 per $1,000 of taxable tangible property OR taxable net worth), minimum $456/year. Filed separately with MA Department of Revenue, NOT with SOS. Wizard must remind customers.
- Personal income tax 5% flat. Plus 4% surtax on income over $1M ("Millionaires Tax", passed 2022, in effect since 2023). Total top rate 9% on income over $1M.
- Annual Report due date is the anniversary of original filing (for Corp, LLC, LP). NOT a fixed calendar date like CT's Mar 31 or FL's May 1.

Common questions.
What is the first step to start a business in Massachusetts?
The first real decision is your entity type, because it drives everything after: taxes, liability, and paperwork. For most small businesses in Massachusetts that means forming an LLC, which you do by filing a formation document with the state and naming a registered agent. Get the structure right first, then EIN, banking, and licenses follow in order. We walk you through the Massachusetts sequence so nothing is done out of turn.
Which business structure should I choose in Massachusetts?
Most Massachusetts founders land on an LLC for its liability protection and simple pass-through taxes, but a corporation makes sense if you plan to raise venture capital or issue stock. A sole proprietorship is simplest but leaves your personal assets exposed. The honest answer depends on your goals, so we lay out the LLC-versus-corporation trade-offs for Massachusetts rather than pushing one.
Do I need a registered agent in Massachusetts?
Yes. Massachusetts requires every LLC and corporation to name a registered agent with a physical in-state address to receive legal and state notices. You can be your own, but then your address is public and you must be available during business hours. Most owners use a service to stay private and never miss a notice. We include agent service so this box is checked from day one.
How much does it cost to start an LLC in Massachusetts?
The cost is the Massachusetts state filing fee plus any service you use, and Massachusetts also charges recurring fees such as an annual or biennial report. Our formation service itself is free, and we pass state fees through at cost with no markup. Because state figures change over time, current Massachusetts amounts are on the pricing page rather than quoted here where they could go stale.
Do I need a business license in Massachusetts?
Often yes, and it is usually layered. Massachusetts may require a state-level license for certain activities, and your city or county frequently adds its own, plus industry permits. Very few businesses need nothing at all. We map every Massachusetts license and permit your specific business needs so you open legally instead of guessing which ones apply.
What taxes will my Massachusetts business pay?
It depends on your structure and activity, but expect some mix of federal income and self-employment tax, Massachusetts state taxes where they apply, and sales tax if you sell taxable goods. Some states have no income tax while others add franchise or gross-receipts taxes. Once profits grow, an S-corp election can reduce self-employment tax. We flag which Massachusetts taxes actually apply to you rather than listing every possibility.
Do I need an EIN for my Massachusetts business?
Almost certainly. You need an EIN to open a business bank account, hire employees, or file most business taxes, and it keeps your Social Security number off company paperwork. It is free from the IRS, and our value is getting it right and fast, including for founders without an SSN. We obtain it as part of setting up your Massachusetts entity so banking is not held up.
Can I form my business in another state instead of Massachusetts?
You can, but if you operate in Massachusetts it usually backfires. Forming in Delaware or Wyoming while doing business in Massachusetts means registering in Massachusetts as a foreign entity anyway and paying two states. The out-of-state advantage is real mainly for venture-backed or holding companies. For a business rooted in Massachusetts, forming at home is almost always cheaper and simpler.
What are the ongoing compliance requirements in Massachusetts?
After formation, Massachusetts expects you to keep a registered agent, file the periodic annual or biennial report, pay any state fees, and renew licenses on schedule. Miss these and the state can revoke your good standing or dissolve the entity. We track your Massachusetts deadlines in a compliance calendar and can file the reports for you so nothing lapses while you run the business.
