How to Start a Business in Maine:

1. Decide on a business structure.

There are four popular business structures available, including:

  • A Sole Proprietorship has no legal difference between the owner and the business. Does not require filing with the state.
  • A partnership is a legally binding agreement between two or more individuals. The partners share management duties and profits.
  • A Limited Liability Company (LLC) is a hybrid business structure that offers limited liability to its owners. Includes certain characteristics of both a corporation and a partnership or sole proprietorship.
  • A corporation is a formal legal structure. It is authorized to act as a single entity and is recognized as such by law.

There are different taxation benefits associated with each business structure. You need to ensure your business structure is financially beneficial, with good liability protection.

Most small business owners prefer opening an LLC because of their flexibility and tax benefits. Depending on the circumstances, an LLC may choose to use corporate tax rules instead of being treated as a partnership. It combines the limited liability of a corporation with the availability of pass-through income taxation of a partnership. You can set up an LLC business in Maine for $175.00.
