What's Next After Filing

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

  • Create Corporate BylawsDraft internal corporate bylaws that govern the management and operations of the corporation, including rules for shareholder meetings, board of directors, officer roles, and voting procedures. While not filed with the state, bylaws are legally important governing documents.
  • Hold an Organizational MeetingConduct the initial organizational meeting of the board of directors to adopt bylaws, appoint officers, authorize the issuance of stock, and address other foundational business matters. Document the meeting with formal minutes.
  • Obtain EIN and Fulfill Tax & Licensing RequirementsApply for a federal Employer Identification Number (EIN) from the IRS, register with the Maine Revenue Services for state tax obligations, and obtain any required local or state business licenses or permits applicable to your industry.

Advantages

  • Limited liability protection shields shareholders' personal assets from corporate debts and legal judgments
  • Ability to raise capital by issuing multiple classes of stock and attracting investors, including venture capital
  • Perpetual existence means the corporation continues regardless of ownership changes or death of shareholders
  • Eligible to elect S-Corp tax status with the IRS to avoid double taxation and pass income through to shareholders
  • Enhanced credibility with customers, vendors, and financial institutions compared to unincorporated entities

Considerations

  • Subject to potential double taxation at both the corporate and shareholder level if operating as a C-Corp
  • More complex formation, governance, and compliance requirements compared to an LLC, including mandatory meetings and record-keeping
  • Higher ongoing administrative burden including annual reports, corporate minutes, and maintaining formalities to preserve liability protection
  • Greater regulatory scrutiny and costs associated with maintaining corporate structure, especially if publicly traded

Annual Obligations

Report Due:June 1
Maine corporations must file an Annual Report with the Secretary of State by June 1 each year. The filing fee is $85 for domestic corporations. Failure to file on time can result in administrative dissolution. Maine does not impose a separate state franchise tax on corporations, but corporations are subject to Maine corporate income tax, which has a graduated rate starting at 3.5% and reaching up to 8.93% on income over $3,500,000.
