Start Your Own Business in Maine: Seven Steps You Need to Take

From licenses and permits to taxes and insurance, learn what you need to do to start a business in Maine.

Here’s an overview of the key steps you’ll need to take to start your own business in Maine.

Step 1. Decide on a Legal Structure

The most common legal structures for a small business are:

  • sole proprietorship
  • partnership
  • limited liability company (LLC), and
  • corporation.

There also are special versions of some of these structures, such as limited partnerships and S corporations. You’ll want to consider which business entity structure offers the type of liability protection you want and the best tax, financing, and financial benefits for you and your business. Check Choose Your Business Structure on Nolo’s website for more information on how to choose the best ownership structure for your business.

Step 2. Choose a Name

For LLCs and corporations, you will need to check that your name is distinguishable from the names of other business entities already on file with the Maine Secretary of State (SOS). Names can be checked for availability by searching the Maine SOS corporate name search. You can reserve an available name for 120 days by filing anApplication for Reservation of Name with the Maine SOS. There are also certain name requirements for LLCs and corporations (like including a word such as “LLC” for LLCs or “Company” for corporations). See How to Form an LLC in Maine and How to Form a Corporation in Maine for more information.

If you plan on doing business online, you may want to register your business name as a domain name. See Choose and Register a Domain Name for more information. In addition, to avoid trademark infringement issues, you should do a federal and state trademark check to make sure the name you want to use is not the same as or too similar to a name already in use. See How to Do a Trademark Search for more information.

Step 3. Create Your Business Entity

  • Sole proprietorship: To establish a sole proprietorship in Maine, you don’t need to file any documents. For more information, see How to Establish a Sole Proprietorship in Maine.
  • Partnership: To create a general partnership in Maine, you don’t need to file any organizational documents with the state. Although not legally required, all partnerships should have a written partnership agreement . The partnership agreement can be very helpful if there is ever a dispute among the partners. For more information, see How to Form a Partnership in Maine. To form a limited liability partnership (often used by professionals), you must file a Certificate of Limited Liability Partnership with the Maine SOS. For more information, see How to Form a Limited Liability Partnership in Maine.
  • LLCs: To create an LLC in Maine, you must file a certificate of formation with the Maine SOS. You will also need to appoint a registered agent in Maine for service of process. Although not required by law, you should prepare an operating agreement to establish the basic rules about how your LLC will operate. The operating agreement is not filed with the state. For more information, see How to Form an LLC in Maine and How to Form a Professional LLC in Maine (for professionals).
  • Corporations: To create a corporation in Maine, you must file articles of incorporation with the Maine SOS. You will also need to appoint a registered agent in Maine for service of process. Although not legally required, you should prepare bylaws to establish your corporation’s internal operating rules. Bylaws are not filed with the state. S Corporations must also file IRS Form 2553, Election by a Small Business Corporation,with the IRS. For more information, see How to Form a Corporation in Maine.

Step 4. Licenses and Permits

Tax Registration. If you will be selling goods in Maine, you must register your business with Maine Revenue Services (MRS). If you will have employees in Maine, you must register with MRS and the Maine Department of Labor (DOL). For both kinds of registration, you can use the MRS/DOL application for tax registration.

EIN. If your business has employees or is taxed separately from you, you must obtain a federal Employer Identification Number (EIN) from the IRS. Even if you are not required to obtain an EIN, there are often business reasons for doing so. Banks often require an EIN to open an account in the business’s name and other companies you do business with may require an EIN to process payments. You can get an EIN by completing an online application on the IRS website. There is no filing fee.

Regulatory licenses and permits. These cover areas such as:

  • health and safety
  • the environment
  • building and construction; and
  • specific industries or services.

General licenses needed to operate a business are handled at the town or city level. You should contact the town or city office where your business is located for more information. You can find contact information for a particular town office through the Local Government portal.

Professional and occupational licenses. These cover people who work in various fields. You can find a list of state-issued professional and occupational licenses at the Resources by Profession section of

Step 5. Business Location and Zoning

You’ll need to pick a location for your business and check local zoning regulations. That includes if you work from home. You may be able to find zoning regulations for your town or city by checking

Step 6. Taxes and Reporting

Maine taxes every kind of business. See Maine State Business Income Tax for more information on state business taxes in Maine.

Sole proprietorships. Pay state taxes on business income as part of their personal state income tax returns (Form 1040ME).

Partnerships. Partners pay state taxes on partnership income on personal tax returns. If your partnership has non-Maine partners, you must also file Form 941P-ME for the partnership.

LLCs. Members pay state taxes on their share of LLC income on personal tax returns. In addition, the LLC itself must file an annual report and pay an $85 filing fee. See Maine LLC Annual Report and Tax Requirements for more information.

Corporations. Shareholders must pay states taxes on their dividends from the corporation. A shareholder-employee with a salary also must pay state income tax on his or her personal state tax return. Moreover, the corporation itself is subject to Maine corporation taxes. And, finally, corporations must file an annual report and pay an annual filing fee of $85.

If you have employees, you must also deal with employer taxes.

And, apart from Maine taxes, there are always federal income and employer taxes. Check IRS Publications 334,Tax Guide for Small Business, and 583, Taxpayers Starting a Business, available at

Step 7. Insurance

Insurance is a good idea for most kinds of business. While insurance often is regulated at the state level, the types of business insurance available are usually similar across the fifty states. Check Obtaining Business Insurance for more information.
