How to start a nonprofit in Massachusetts

Short answer: To start a nonprofit in Massachusetts, you incorporate by filing Articles of Organization with the Secretary of the Commonwealth, Corporations Division ($35 as of 2026), get a free EIN from the IRS, adopt bylaws, and seat a board with at least a president, treasurer, and clerk. Then comes the part people miss: a nonprofit is not automatically tax-exempt, so you file IRS Form 1023 (or 1023-EZ) to become a 501(c)(3). On the Massachusetts side, you register with the Attorney General’s Non-Profit Organizations/Public Charities Division before you solicit donations (initial fee $100), file the Form PC every year, and — unlike many states — you can claim a real sales tax exemption from the Department of Revenue, which issues a Certificate of Exemption (Form ST-2) you then use with Form ST-5 at the register. The honest warning most guides bury: the charitable registration is required, not optional, and skipping it can stall your fundraising before it starts.

The federal core — EIN, bylaws, board, and the 501(c)(3) application — is the same in every state. For the full national walkthrough, read how to start a nonprofit; this page focuses on the Massachusetts layer stacked on top of it, where the state-specific forms, fees, and agencies actually live.

The formation steps that are the same anywhere

Forming a nonprofit in Massachusetts follows the standard checklist, and most of it is federal rather than state-specific:

1. Incorporate as a nonprofit corporation under Chapter 180 (the Massachusetts-specific part — covered in detail below).
2. Get an EIN — a free federal tax ID from the IRS, applied for directly at irs.gov. Never pay a third party for one; the EIN is always free.
3. Adopt bylaws — the organization’s internal rulebook for decisions, leadership, and money. Start from a proven document rather than a blank page; see nonprofit bylaws for what to include.
4. Seat a board of directors who govern the organization, set policy, and hold it accountable.
5. Apply for 501(c)(3) with Form 1023 — this is the step that turns a nonprofit corporation into a tax-exempt charity. Unlike a church, an ordinary nonprofit is not automatically exempt; you must file IRS Form 1023 (or the streamlined Form 1023-EZ if you qualify) and receive a determination letter (IRS, applying for 501(c)(3) status). The full path is in how to start a 501(c)(3).
6. Open a bank account in the nonprofit’s legal name using the EIN and formation documents.
7. Set up the books on fund accounting from day one, before the first grant or donation arrives.

Each of these is walked step by step in the national formation guide linked above. The rest of this page is the Massachusetts layer on top.

Incorporating a nonprofit in Massachusetts

Massachusetts creates the nonprofit as a legal entity when you file Articles of Organization under General Laws Chapter 180 with the Secretary of the Commonwealth, Corporations Division. The filing fee is $35 as of 2026 (filing by fax or online adds a small expedite fee), and you can submit online, by fax, by mail, or in person; confirm the current amount with the Secretary of the Commonwealth, Corporations Division, since fees change.

The Articles of Organization ask for the nonprofit’s name, its purpose, and its officers and directors. Two clauses matter for what comes next with the IRS, and you should write them in rather than leave them out:

• A 501(c)(3) purpose clause stating the organization is formed exclusively for charitable, religious, educational, or other exempt purposes.
• A dissolution clause stating that if the nonprofit closes, its assets pass to another 501(c)(3) organization, not to any individual.

Getting that language right at formation saves an amendment later. The full breakdown of what these documents need is in articles of incorporation. On people: a Chapter 180 corporation must have a president, a treasurer, and a clerk, and the clerk must be a Massachusetts resident unless the corporation appoints a resident agent (Mass. General Laws c.180 § 6A). The state will approve a filing with as few as one director, but three mostly-unrelated directors is the practical standard, and the IRS treats a one-person board as a red flag on the 1023.

One ongoing duty the state requires of every Chapter 180 corporation: a Non-Profit Annual Report filed with the Corporations Division on or before November 1 each year, carrying a $15 fee as of 2026 (Secretary of the Commonwealth, non-profit corporation filing). The annual report keeps your officers, directors, and address current on the public record; let it lapse and the corporation can fall out of good standing.

Registering with the Massachusetts Attorney General

Here is the step that trips up nonprofits coming from a church background, where it often does not apply: Massachusetts requires public charities to register with the Attorney General’s Non-Profit Organizations/Public Charities Division when they begin operating in the Commonwealth, and a charity must hold a valid registration before it solicits contributions from the public. A general nonprofit asking the public for money cannot skip this.

Registration runs through the Attorney General’s online Charity Portal, which has been the required channel for charitable registrations since September 1, 2023 (Massachusetts Attorney General, online charity filing portal). A first-time registrant submits the registration form with supporting documents — Articles of Organization, bylaws, and the IRS determination letter if you have it — and the office issues an Attorney General Account Number for all future filings. The initial registration fee is $100 as of 2026, with an additional $50 Schedule A-2 fee in certain cases; confirm the current schedule with the Attorney General before paying, since the fees are tied to the registration form you file.

Registration is not one-and-done. Every year afterward, a public charity files the Form PC with the Attorney General, due four and one-half months after the end of its fiscal year, along with its IRS Form 990 and any required financial statements. The Form PC fee is not flat — it scales with the organization’s revenue, running roughly $35 to $2,000 depending on size — and the same filing renews the Certificate of Solicitation a charity needs to keep fundraising (Massachusetts Attorney General, Form PC instructions). Confirm the current fee tiers with the Attorney General before filing.

Claiming the Massachusetts sales tax exemption (ST-2)

Massachusetts is more generous than many states here: a qualifying 501(c)(3) can be exempt from the 6.25% sales and use tax on its purchases. The exemption is not automatic, though — it is a separate application to the Department of Revenue (DOR), and it works through two forms that people constantly mix up.

You apply through MassTaxConnect, attaching your IRS determination letter, and once DOR approves the organization it mails back a Certificate of Exemption, Form ST-2 (Mass. DOR, AP 101: organizations exempt from sales tax). The ST-2 is the proof that your nonprofit qualifies. To actually buy something tax-free, you then hand the vendor a completed Form ST-5, Sales Tax Exempt Purchaser Certificate, with a copy of your Form ST-2 attached, and the goods must be used for the organization’s exempt purposes. So the mechanism is: DOR issues the ST-2 to you; you issue the ST-5 (plus a copy of the ST-2) to your vendors. One detail to put on the calendar — a Form ST-2 carries a five-year limit and has to be renewed, so treat the certificate as something to track, not file and forget.

A note on income tax while you are with the DOR: a corporation that has received its federal 501(c)(3) exemption is generally exempt from the Massachusetts corporate excise as well, though income from an unrelated business can still be taxable (Mass. DOR, corporate excise tax exemptions). The federal determination letter does most of the work here; there is no separate state income-tax exemption application the way some states require.

Setting up the books once the nonprofit exists in Massachusetts

Once the entity is formed and the registrations are filed, the work shifts from one-time paperwork to the monthly routine — and that routine is where nonprofits either hold together or quietly fall apart. A nonprofit holds money in trust for the people and purposes it serves, much of it restricted by donors or grant terms, so it tracks money by fund rather than as a single bottom line. Set the books on fund accounting before the first grant lands, keep the giving records donors need, and document that the board reviews the finances; the discipline is covered in nonprofit accounting. The Massachusetts angle to keep on your calendar is the Form PC — that annual filing to the Attorney General is what keeps your charitable registration and your Certificate of Solicitation current, and letting it slip can interrupt your right to fundraise.

FAQ

How much does it cost to start a nonprofit in Massachusetts? The required state cost is modest. Filing Articles of Organization with the Secretary of the Commonwealth costs $35 as of 2026, and the Attorney General’s initial charity registration is $100 — so the Massachusetts paperwork runs about $135 plus your time, before the annual report ($15) and yearly Form PC come due. The bigger line item is federal: the IRS charges a $275 user fee for Form 1023-EZ or $600 for the full Form 1023, which is what actually makes you a 501(c)(3). Applying for the sales tax exemption (Form ST-2) through the Department of Revenue carries no fee. Realistically, a small Massachusetts nonprofit can be stood up properly for a few hundred dollars once you include the federal exemption application.

Do you have to register a nonprofit with the Massachusetts Attorney General? Yes. Public charities operating in Massachusetts must register with the Attorney General’s Non-Profit Organizations/Public Charities Division, and a charity must hold a valid registration before it solicits contributions from the public (Massachusetts Attorney General, online charity filing portal). Registration is separate from incorporating with the Secretary of the Commonwealth and separate from your IRS 501(c)(3) application — it is the charitable and fundraising registration, and skipping it can stall your fundraising before you have raised a dollar. After the initial filing, you renew every year with the Form PC.

Does Massachusetts exempt nonprofits from sales tax? Yes, which makes Massachusetts friendlier than many states. A qualifying 501(c)(3) applies through MassTaxConnect, and the Department of Revenue issues a Certificate of Exemption, Form ST-2. To buy tax-free, the nonprofit then gives vendors a Form ST-5 with a copy of its ST-2 attached, for purchases used for its exempt purposes (Mass. DOR, AP 101). The ST-2 is good for five years and has to be renewed, so put the expiration date on your compliance calendar.

How long does it take to start a nonprofit in Massachusetts? The Massachusetts incorporation itself is relatively quick — the Corporations Division processes Articles of Organization in a matter of days when filed online, faster than by mail. The slow part is federal: the IRS can take anywhere from about a month (Form 1023-EZ) to many months (full Form 1023) to issue the 501(c)(3) determination letter, and you generally want that letter in hand before applying to the Department of Revenue for the Form ST-2 sales tax exemption. Plan for the state entity to exist within a week or two but the full tax-exempt status to take several months end to end.
