What's Next After Filing

Once your S-Corp is officially formed, you'll want to complete these important steps:

  • Hold Organizational Meeting & Issue StockConduct an initial organizational meeting of the board of directors to appoint officers, adopt bylaws, and authorize the issuance of stock. Issue shares only to eligible S-Corp shareholders (individuals, certain trusts; no more than 100 shareholders).
  • Obtain EIN and Elect S-Corp Status with IRSApply for a federal Employer Identification Number (EIN) from the IRS at no cost, then file IRS Form 2553 (Election by a Small Business Corporation) to elect S-Corporation tax status. The election must be filed no later than 2 months and 15 days after the beginning of the tax year it is to take effect.
  • Register for Massachusetts State TaxesRegister with the Massachusetts Department of Revenue (MassTaxConnect) for applicable state taxes, including withholding tax if you have employees and corporate excise tax. Massachusetts recognizes the federal S-Corp election for state tax purposes.

Advantages

  • Pass-through taxation avoids double taxation — corporate income passes directly to shareholders and is taxed only at the individual level on Massachusetts and federal returns.
  • Shareholders who are active employees can reduce self-employment/FICA tax liability by splitting compensation between reasonable salary and distributions.
  • Provides limited liability protection, shielding shareholders' personal assets from corporate debts and legal judgments.
  • Massachusetts recognizes the federal S-Corp election, simplifying state tax compliance and aligning state treatment with federal pass-through status.

Considerations

  • Strict IRS eligibility restrictions limit S-Corps to 100 shareholders, one class of stock, and only allowable shareholders (U.S. citizens/residents, certain trusts), restricting growth and outside investment options.
  • More administrative burden than an LLC, including requirements to hold annual meetings, maintain meeting minutes, and adhere to formal corporate governance structures.
  • Massachusetts subjects S-Corps to the corporate excise tax and associated minimum fees, adding a state-level tax cost not present for LLCs taxed as partnerships.

Annual Obligations

Annual Report Fee:$125
Report Due:March 15
Massachusetts S-Corporations must file an Annual Report with the Secretary of the Commonwealth by March 15 each year, with a $125 filing fee. Additionally, S-Corps are subject to the Massachusetts corporate excise tax, which includes an $8.00 per $1,000 of taxable Massachusetts net income plus a minimum fee based on gross receipts (ranging from $456 to $100,000). Shareholders pay personal income tax on passed-through income at the Massachusetts rate of 5% (or 8.5% for short-term gains and certain dividends).
