Massachusetts Corporation Requirements and Compliance

To form a corporation in Massachusetts, you file Articles of Organization with the Secretary of the Commonwealth under Chapter 156D of the General Laws. The base filing fee is $275, which covers up to 275,000 authorized shares.¹ Before you file, you need a name the state will accept and a basic governance structure in mind. After you file, you need a federal EIN, and from year one you need to keep up with the annual report and the corporate excise tax.

Pick a Corporate Name the State Will Accept

Your proposed name has to be distinguishable from every other entity already registered in Massachusetts. The Secretary of the Commonwealth will reject your filing if the name is the same as, or confusingly similar to, an existing corporation or other registered business.²

If you want to lock a name in before you’re ready to file, submit an Application of Reservation of Name with a $30 fee. The reservation holds for 60 days, and you can extend it once for another 60 days with a second $30 payment.² That window gives you room to finalize bylaws, line up directors, and handle other formation details without worrying that someone else will take the name first.

File the Articles of Organization

The Articles of Organization is the document that actually creates the corporation. It’s filed with the Secretary of the Commonwealth under Chapter 156D, Section 2.02. The form requires:

the corporation’s exact legal name
its business purpose
the name and address of the initial registered agent
the names and addresses of the initial directors, president, treasurer, and secretary¹

Unless you write in a narrower purpose, the corporation is automatically authorized to engage in any lawful business activity. Most incorporators keep the purpose broad to preserve flexibility.

Expect the share count to drive your fee. The $275 base covers up to 275,000 authorized shares. Above that, you pay an additional $100 for each 100,000 shares (or fraction) beyond the first 275,000.¹ First-time incorporators who authorize a large block of shares at a low par value, assuming the fee is flat, sometimes get caught by this.

Get a Federal EIN

Once the state approves your Articles of Organization, apply to the IRS for an Employer Identification Number. You need an EIN to hire employees, open a business bank account, and file corporate tax returns. The IRS issues EINs free and specifically warns against third-party websites that charge for the service.³

The online application is the fastest route and issues the EIN immediately. You have to finish it in one session (it can’t be saved and times out after 15 minutes of inactivity), and the IRS limits applicants to one EIN per responsible party per day. The online tool runs Monday through Friday, 6 a.m. to 1 a.m. Eastern, with reduced weekend hours.³ Form the entity with the state first; the IRS may delay the application if you haven’t.

Set Up the Required Officers and Directors

Massachusetts law sets a minimum governance structure that your articles and bylaws have to meet.

Board of Directors

Every Massachusetts corporation must have a board of at least one director, with the exact number set in the articles of organization or bylaws.⁴ Directors are elected by shareholders and owe fiduciary duties to act in the corporation’s best interests, exercise reasonable care, and avoid conflicts of interest. One director is fine for a single-owner corporation; expanding the board makes sense as the business takes on investors.

Officers

Every corporation must have at least a president, treasurer, and secretary. The bylaws or the board can add other officer positions.⁵ The secretary prepares minutes of directors’ and shareholders’ meetings and authenticates corporate records. One person can hold multiple officer titles, which is common in small corporations where the sole owner is president, treasurer, and secretary all at once.

If you’re working from older guidance that mentions a mandatory Massachusetts-resident “clerk,” that’s out of date. Chapter 156B’s resident clerk requirement was replaced by Chapter 156D’s “secretary,” and there’s no residency requirement.

Choose the Right Type of Corporation

The structure you choose affects taxes, ownership flexibility, and in some cases reporting obligations. The decision is usually made at or just after filing.

C Corporation vs. S Corporation

A C corporation is the default. It gives limited liability and can issue unlimited shares to any number of investors, which makes it the standard vehicle for businesses planning to raise outside capital. The tradeoff is double taxation: the corporation pays tax on its profits, and shareholders pay tax again on dividends.

An S corporation avoids that second layer by passing income and losses through to shareholders’ personal returns. The federal eligibility rules are strict: no more than 100 shareholders, all U.S. citizens or residents, and only one class of stock. The S election is made at the federal level with IRS Form 2553. Massachusetts generally follows the federal S election for state tax purposes, though S corporations still file a state return.

Professional Corporations

Licensed professionals such as doctors, lawyers, and accountants can form professional corporations under Chapter 156A.⁶ These entities carry limited liability while allowing the owners to practice their licensed profession through a corporate structure. They face extra filing requirements, including attaching regulatory board approval at registration and listing the names, addresses, and licensed services of all shareholders in annual reports.⁷

Benefit Corporations

Massachusetts has authorized benefit corporations under Chapter 156E since December 2012. Directors of a benefit corporation are expressly permitted to consider and prioritize social and environmental impacts in their decisions, rather than focusing solely on financial returns.⁸ The corporation still operates for profit and can distribute earnings to shareholders.

Expect an added reporting layer. Along with the standard annual report, benefit corporations must file a benefit report describing their activities implementing their public benefit mission, including an assessment of overall social and environmental performance measured against a third-party standard. The benefit report is filed as a narrative attachment and carries an additional $75 fee on top of the regular annual report fee.⁸

Keep the Corporation in Good Standing

Annual Report

Every Massachusetts corporation must file an annual report with the Secretary of the Commonwealth under Chapter 156D, Section 16.22. The standard fee is $125; electronic filing drops it to $100. Missing the deadline bumps the fee to $150.⁹ Repeated failure to file can eventually lead the state to administratively dissolve the corporation, which creates real problems if you later need to enforce contracts or defend a lawsuit.

Corporate Excise Tax

Massachusetts imposes a corporate excise tax with two components: an income measure (currently 8% on income attributable to Massachusetts) and a non-income measure based on tangible personal property or net worth. A corporation doing business in the state, owning property there, or employing workers there is generally subject to this tax.¹⁰

C corporations file by the 15th day of the fourth month after the close of their tax year. S corporations file by the 15th day of the third month. Corporations expecting to owe more than $1,000 in excise tax must make estimated quarterly payments.¹¹

Records

Beyond government filings, Massachusetts corporations must maintain accurate records of financial transactions, meeting minutes, and shareholder actions. Shareholders have the right to inspect those records. Keeping them organized is also the single best defense if someone later tries to go after the owners personally.

Protect the Liability Shield

The core payoff for incorporating is limited liability: shareholders are not personally responsible for corporate debts beyond their investment. Creditors can reach corporate assets, but your personal bank account, home, and other property are generally off-limits.

That protection is not absolute. Massachusetts courts will “pierce the corporate veil” and hold shareholders personally liable when the facts justify it. The standard requires showing either active and pervasive control of the business entity by the same people with a fraudulent or injurious consequence, or a confused intermingling of corporate activity with substantial disregard for the corporation’s separate existence. Courts weigh whether the corporation was adequately capitalized, whether formalities were observed, whether records were kept, and whether owners treated corporate funds as their own.

The practical takeaway is straightforward. Keep separate bank accounts. Hold your annual meetings, even if it’s just you in a room signing a resolution. Keep minutes. Don’t run personal expenses through the corporate checking account. Corporations that actually function like corporations rarely get their veil pierced.

If the Corporation Was Formed Outside Massachusetts

If your corporation was formed in another state and you now want to do business in Massachusetts, you don’t file Articles of Organization. You file a foreign corporation certificate of registration with the Secretary of the Commonwealth within 10 days of starting to transact business.⁷ The fee is $400, or $375 by fax.⁹ The application must include a certificate of good standing from the home jurisdiction, and if the name is already taken in Massachusetts, the corporation has to agree not to do business under that name here. Once registered, foreign corporations face the same annual report requirements as domestic ones.

Federal Beneficial Ownership Reporting

One federal filing people frequently ask about doesn’t currently apply to Massachusetts-formed corporations. In March 2025, the Financial Crimes Enforcement Network issued an interim final rule exempting all U.S.-formed companies from the beneficial ownership reporting requirements of the Corporate Transparency Act. Only entities formed under foreign law and registered to do business in a U.S. state are currently required to file beneficial ownership reports with FinCEN.¹² If your corporation is formed in Massachusetts, you don’t need to file a BOI report under the current rule.
