S-Corp Election in Massachusetts (Form 2553) (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

You make an S-corp election in Massachusetts by filing IRS Form 2553 no later than 2 months and 15 days after the start of the tax year the election should take effect. Massachusetts recognizes the federal election automatically — there is no separate state form — but the S corporation still files Massachusetts Form 355S and pays an entity-level corporate excise with a $456 minimum.

What an S-Corp Election Is

An "S corporation" is not a kind of entity you form with the state — it is a federal tax election. You first have a corporation or a limited liability company, then you ask the IRS to tax it under Subchapter S of the Internal Revenue Code. Making the election changes how profits are taxed: instead of the entity paying corporate income tax (a C corporation) or the owner paying self-employment tax on all profit (a default LLC), income passes through to owners, who can be paid a salary plus distributions. For the broader comparison, see S-Corp vs LLC and our business tax hub.

The election is made on IRS Form 2553, and every shareholder (or LLC member) must consent. Because the S election is federal, the same Form 2553 works whether your entity is organized in Massachusetts or another state. What sets Massachusetts apart is the state side: unlike states that leave S corporations untaxed at the entity level, Massachusetts recognizes the federal election yet still charges a corporate excise on the S corporation itself. This guide explains eligibility, the deadline, and the Massachusetts obligations that continue after you elect.

It helps to understand what you are electing away from. By default, a single-member LLC is a disregarded entity and a multi-member LLC is a partnership, so all net profit is subject to self-employment tax on the owners' returns. A corporation that makes no election is a C corporation, taxed at the entity level and again when profits are distributed as dividends — the classic "double taxation." The S election is the middle path: a single federal layer of tax, income passing through to owners, and the ability to characterize part of an owner-employee's return as wages and part as distributions.

Eligibility Requirements for S-Corp Status

To qualify for an S election, the entity must be a domestic corporation or LLC and meet strict shareholder rules. It may have no more than 100 shareholders, and all shareholders must be eligible — generally U.S. citizens or resident individuals, certain trusts, and estates. It may not have nonresident alien shareholders, and it may have only one class of stock (differences in voting rights are allowed, but not differences in distribution or liquidation rights). Partnerships and corporations generally cannot be shareholders.

An LLC can elect S status if it meets these tests; the check-the-box rules treat the Form 2553 as also electing corporate classification, so a separate Form 8832 is usually not required. Before electing, confirm your ownership structure fits the rules and make sure your entity is in good standing. You can verify status with the Massachusetts business entity search and review single-member LLC mechanics if you own the business alone.

How to Make the Election, Step by Step

1. Confirm eligibility. Check the shareholder count, eligible-owner, and one-class-of-stock tests above so the IRS does not reject the election.
2. Get an EIN. The entity needs a federal EIN before filing; the number and entity details go on Form 2553.
3. Complete and file Form 2553. Enter the effective date, the tax year, and every shareholder's name, ownership, and signed consent. File by mail or fax to the IRS service center for your state within the deadline.
4. Address Massachusetts treatment. No separate Massachusetts election is needed. Going forward, file Massachusetts Form 355S, pay the corporate excise, and keep the entity's annual report and registered agent current.
5. Set up payroll. Put owner-employees on payroll at a reasonable salary, withhold and remit employment taxes, and document how distributions are handled.

Keep a copy of the accepted election (the IRS sends a CP261 notice) with your records. If you missed the deadline, the IRS provides late-election relief under Revenue Procedure 2013-30 when you had reasonable cause and have otherwise acted as an S corporation for the period involved.

The Form 2553 Deadline

Timing is the most common trap. To take effect for the current tax year, Form 2553 must be filed no later than 2 months and 15 days after the beginning of that tax year. For a calendar-year business starting January 1, that puts the deadline around March 15. You may also file at any time during the preceding tax year for an election effective the following year. A newly formed entity's tax year begins when it first has shareholders, acquires assets, or begins doing business — whichever is earliest — so new owners should calendar the deadline immediately after formation with the Secretary of the Commonwealth.

Miss the window and the entity is taxed under its default rules for the year unless it qualifies for relief. Late-election relief lets many businesses still obtain the intended effective date by attaching a reasonable-cause statement to a properly completed Form 2553. Because the consequences of a rejected or late election are real, confirm the current instructions on the IRS Form 2553 page before filing, and see how to form an LLC in Massachusetts if you are still choosing an entity.

Massachusetts Corporate Excise on S Corporations

This is where Massachusetts diverges from most states. Even after a valid federal S election, Massachusetts imposes a corporate excise on the S corporation itself, filed on Form 355S with the Massachusetts Department of Revenue. The excise has two components. First, a non-income measure of $2.60 per $1,000 of the corporation's taxable Massachusetts tangible property or, if applicable, its net worth. Second, an income measure that applies only to S corporations with total receipts of $6 million or more: 2.0% of net income for receipts between $6 million and $9 million, and 3.0% for receipts of $9 million or more. Below the $6 million receipts threshold, the income measure does not apply.

Whatever those two measures produce, the corporate excise is subject to a minimum of $456. An S corporation that owes less — including one with little property and modest receipts — still pays at least the $456 minimum when it files. Separately, the pass-through income flows to shareholders, who report their shares on their Massachusetts personal income tax returns; resident shareholders are taxed on their full share and nonresidents on Massachusetts-source income. Entity registration is handled by the Secretary of the Commonwealth, while the excise and personal income tax are administered by the Department of Revenue. See Massachusetts LLC tax filing and Massachusetts LLC cost for the entity-level fees.

The practical takeaway is that a Massachusetts S election never eliminates state-level filing. You budget for two returns and two kinds of tax: the entity's Form 355S with its corporate excise, and each owner's personal income tax on the pass-through share. That is different from states with no entity-level tax on S corporations, and it matters most for capital-intensive businesses (which feel the non-income measure on tangible property) and for higher-revenue businesses that cross the $6 million receipts threshold and pick up the income measure. Model both measures against your property, net worth, and receipts before assuming the election saves money, and keep the Massachusetts DBA filing and entity records consistent with what you report to the state.

Reasonable Salary and Payroll Obligations

The tax advantage of an S corporation comes from splitting an owner-employee's pay between a salary and distributions. Only the salary is subject to Social Security and Medicare (payroll) taxes; distributions are not subject to self-employment tax. To prevent abuse, the IRS requires that S-corporation shareholder-employees be paid reasonable compensation for the services they perform before taking distributions. Paying an artificially low salary to dodge payroll tax is a frequent audit target.

Practically, that means running real payroll: registering as an employer, withholding income and FICA taxes, filing federal Forms 941 and 940, issuing a W-2, and meeting Massachusetts withholding requirements. These added costs, together with the corporate excise and its $456 minimum, are why an S election in Massachusetts usually makes sense only once profits comfortably exceed a reasonable salary.

Frequently Asked Questions

Does Massachusetts require a separate state S-corp election?

No. Massachusetts recognizes a corporation or LLC with a valid federal S election automatically; there is no separate state election form. However, the S corporation still files Massachusetts Form 355S and pays the corporate excise at the entity level.

What is the deadline to file Form 2553 for a Massachusetts business?

File no later than two months and 15 days after the beginning of the tax year the election should take effect, or any time during the preceding tax year. Late elections may qualify for relief under Revenue Procedure 2013-30.

Do Massachusetts S corporations pay entity-level tax?

Yes. Massachusetts imposes a corporate excise on S corporations: a non-income measure on tangible property or net worth and, for S corporations with total receipts of $6 million or more, an income measure, subject to a $456 minimum.

What is the minimum corporate excise in Massachusetts?

The minimum corporate excise is $456. An S corporation that owes less under the non-income and income measures still pays at least this amount to the Department of Revenue when it files Form 355S.

How is S corporation income taxed to Massachusetts owners?

Pass-through income flows to shareholders, who report their shares on their Massachusetts personal income tax returns. Owner-employees must first receive reasonable compensation subject to payroll tax before taking distributions.
