How to Register Your Business in Maine in 7 Simple Steps

Starting a business in Maine is a hassle-free experience when you’re well-informed about the necessary steps. Implement this expert 7-step process to facilitate the prompt registration of your Maine-based business.

Step 1: Determine Your Business Structure

The appropriate business structure for your Maine-based enterprise depends on the nature of your business and your growth objectives. You can choose from several incorporated and unincorporated business types. The following is a brief overview of each structure and its associated requirements.

Please note that only certain business structures require registration with the Maine Secretary of State, such as those necessitating incorporation.

Sole Proprietorship

In Maine, a sole proprietorship is the simplest business structure, with the owner and business considered the same legal entity. The owner is personally responsible for the business’s debts and liabilities. Establishing a sole proprietorship is relatively easy and has limited legal and administrative requirements. In Maine, you do not need to register a sole proprietorship with the state, but you may need to obtain local permits or licenses.

General Partnership

A general partnership is a business owned by two or more individuals who share profits and losses. Each partner is personally liable for the business’s debts and legal obligations. In Maine, you do not need to register a general partnership with the state, but you may need to file a “Maine Assumed Name Certificate” (DBA) in the county where your business is located.

Limited Partnership (LP)

In Maine, a limited partnership consists of one or more general partners who manage the business and assume unlimited personal liability and one or more limited partners who contribute capital but have limited liability. To establish an LP in Maine, you must file a “Certificate of Limited Partnership” with the Maine Secretary of State.

Limited Liability Company (LLC)

An LLC is a flexible business structure that offers the limited liability protection of a corporation while maintaining the tax benefits and simplicity of a partnership. In Maine, you must file a “Certificate of Formation” with the Maine Secretary of State and create an Operating Agreement to outline the company’s management and ownership structure.


A corporation is a separate legal entity from its owners (shareholders) and provides limited liability protection. Two types of corporations exist in Maine:

  • C-corporations
  • S-corporations

To establish a corporation in Maine, you must file “Articles of Incorporation” with the Maine Secretary of State. Corporations necessitate more formalities, such as creating bylaws, issuing stock, and holding regular board and shareholder meetings.

Choose the business structure in Maine that best suits your needs based on liability protection, taxation, and management requirements. Consult with a legal or business professional if you need assistance in making this decision.

Step 2: Select a Unique Business Name

In Maine, there are several avenues available for naming your business. You can choose a name by registering a legal entity name, obtaining a trademark, or registering a legal name while operating under a different one. It’s important to note that naming rules and regulations vary from state to state, so it’s necessary to review the specific requirements for Maine.

Similar to the process of incorporating your business, the naming approach you select in Maine will depend on the individual needs and circumstances of your entity.

While you have the option to pursue all three routes to ensure the exclusivity of your business name, you can also opt to utilize a single option. Although it’s not mandatory, it’s recommended to use the same name for each registration method.

Let’s explore the details of each naming option in Maine:

In Maine, businesses must register a legal entity name, which serves as the official identification of the company by the state. Entity names need to be unique, ensuring that your business is protected from the possibility of another entity having the same name.

Maine’s naming laws encompass guidelines regarding company suffixes (e.g., LLC, LP, or Corp) and require the name to accurately reflect the type of business being registered. You can check for name availability by utilizing the Maine Secretary of State’s database.


In Maine, a trademark serves as a form of intellectual property protection for a business name or logo on a national level. To safeguard your name or logo, it’s crucial to conduct a comprehensive search in the USPTO database to ensure it’s not already registered.

Upon registration, a trademark grants exclusivity and prohibits others from using the same or similar name or logo for similar goods or services, providing nationwide protection. However, it’s important to note that obtaining a trademark does not automatically grant the right to use the name or logo in all circumstances.

Doing Business As (DBA)

In Maine, you have the option to register your business under an official name while operating under a different one. This is known as a Doing Business As (DBA) name. To establish a DBA, you must file a Certificate of Assumed Name with the appropriate county clerk’s office where your business is located. While these names are subject to federal trademark laws, there is no requirement for a DBA to be unique at the state level.

By understanding and considering these naming options, you can successfully register your business name in Maine and protect your brand identity.

Step 3: Consider Taxes and Other Costs in Maine

When operating a business in Maine, it’s essential to consider taxes and other associated costs. Understanding the tax obligations and potential expenses will help you effectively manage your finances and make informed business decisions. Here are some key points to consider:

Maine Sales Tax

  • Maine has a statewide sales tax of 5.5%
  • The sales tax applies to most goods and services sold in Maine, with a few exceptions
  • Businesses that sell taxable goods or services in Maine are required to collect sales tax from their customers
  • Businesses can remit sales tax to the Maine Department of Revenue by mail, online, or through a third-party vendor

Maine Income Tax

  • Maine has a graduated income tax rate ranging from 5.8% to 7.15%
  • The income tax is assessed on the net income of individuals and businesses
  • Individuals and businesses must file an income tax return with the Maine Department of Revenue if their net income exceeds certain thresholds
  • The income tax can be paid by mail, online, or through a third-party vendor

Employer Payroll Tax Withholding

All employers in Maine are required to withhold federal taxes from their employee’s wages. The taxes that must be withheld include the following:

  • Social Security tax (6.2%)
  • Medicare tax (1.45%)

Federal income tax (varies)

Employers are also required to pay a portion of these taxes to the federal government. For more information on employer payroll tax withholding, please visit the IRS website.

In addition to the taxes mentioned above, Maine businesses may also be subject to other taxes, such as excise taxes, property taxes, and franchise taxes. Please consult with a tax professional to determine which taxes apply to your business.

Simplifying the registration procedure, business owners in Maine can avail themselves of online services such as ZenBusiness. Esteemed for its expertise, ZenBusiness provides an array of services aimed at assisting entrepreneurs in registering their businesses, encompassing the submission of filings to the Secretary of State, procurement of an Employer Identification Number (EIN), and establishment of an operating agreement. 

Moreover, ZenBusiness offers ongoing compliance support to ensure businesses maintain favorable compliance standing within the state.

Step 4: Register and Acquire Licenses and Permits in Maine

To ensure legal compliance and operational readiness, it’s necessary to apply for the appropriate licenses and permits for your business. Here are the key registrations and permits you need to consider:

Tax Registration: If you plan to sell goods in Maine or employ individuals within the state, you must register your business with the Maine Revenue Services (MRS) and the Maine Department of Labor (DOL). The MRS/DOL application for tax registration can be used for both types of registration.

Employer Identification Number (EIN): If your business has employees or is subject to separate taxation, obtaining a federal Employer Identification Number (EIN) from the IRS is essential. Even if not mandatory, obtaining an EIN can be beneficial for business purposes, such as opening a business bank account or facilitating payment processing. You can acquire an EIN by completing an online application without any filing fees.

Regulatory Licenses and Permits: These pertain to various areas, including health and safety, environmental regulations, building and construction, and specific industries or services. The specific licenses required for your business are typically managed at the local level by the town or city authorities. Contact the appropriate town or city office where your business is located for detailed information. The Maine Local Government Portal provides contact information for town offices.

Professional and Occupational Licenses: These licenses are specific to individuals working in various professions or occupations. The state website offers a comprehensive list of professional and occupational licenses issued at the state level. You can refer to the Resources by Profession section on the state website for further details.

Ensuring compliance with these licensing and permit requirements will help your business operate within the legal framework and maintain necessary certifications for your industry or profession. It’s advisable to seek guidance from the relevant authorities and complete the application processes on time.

Step 5: Open a Bank Account For Your Business in Maine

Once you have obtained your EIN, you can proceed to open a business bank account in Maine.

The laws governing LLPs, LLCs, and corporations necessitate the establishment of a business bank account. However, sole proprietors and unincorporated partnerships are not legally required to maintain separate personal and business accounts.

Opening a business account in Maine is a straightforward process involving a visit to a local bank and the completion of the requisite paperwork. It’s prudent to conduct a thorough evaluation of different banking institutions, comparing their rates and advantages, before selecting a specific provider.

Even if you operate as a sole proprietor or an unincorporated partnership in Maine, it’s advisable to maintain a designated company bank account to ensure the segregation of personal and business finances. This will prove beneficial in case you decide to incorporate your business at a later stage, saving you potential inconveniences.

Step 6: Protect Your Intellectual Property in Maine

When establishing a business in Maine, it’s crucial to consider the protection of your valuable intellectual property (IP) assets, depending on the nature of your company.

For instance, most businesses aim to safeguard their name and logo from unauthorized replication and usage by others. Depending on whether your business involves selling goods or offering services, you may also want to protect the design of your products or the creative works (such as writing, designs, or music) that you produce.

Maine offers various avenues for protecting your IP, and it’s advisable to initiate the necessary applications promptly to prevent unauthorized use of your intellectual property.

File a Trademark with Bizee


In Maine, a trademark is a recognizable symbol, phrase, word, or design that distinguishes a product or service from similar offerings in the market.

To obtain legal protection, trademarks must be registered with the United States Patent and Trademark Office (USPTO). The registration process typically takes four to six months. Once registered, the trademark is safeguarded nationwide, and legal action can be taken against any unauthorized use.

Businesses in Maine can protect their trademarks by registering them with the USPTO. This not only safeguards their brand and reputation but also provides legal recourse against unauthorized use of the trademark.

In Maine, original works of authorship, such as literary, dramatic, musical, artistic, and certain other intellectual works, are protected by copyright law. This includes written content, software, web content, films, sound recordings, images, and other forms of creative expression.

When you create a new work in Maine, copyright protection is automatically granted to you as the creator. As the owner of exclusive rights to distribute, reproduce, create derivative works, and sell intellectual property, you have the legal authority to control the use of your work.

However, registering your copyright with the U.S. Copyright Office can provide additional legal protection and serve as evidence of ownership. Registering your copyright in Maine helps protect your work against infringement and provides a means to enforce your rights in court, if necessary.


If you invent a new product or piece of machinery in Maine, obtaining a patent is crucial. A patent grants the holder exclusive rights over the item, preventing others from making, selling, or importing the patented invention for a specified period.

The patent process is complex and can take up to five years to complete. Therefore, it’s advisable to initiate the process early if you have a unique invention that requires protection. Patent applications are submitted to the United States Patent and Trademark Office (USPTO).

By protecting your intellectual property in Maine, you can safeguard your brand, products, and creations, ensuring that your business maintains a competitive edge and continues to thrive.

File a Trademark with Bizee

Step 7: Set Up Your Payment Infrastructure in Maine

To ensure the prompt commencement of your registered business operations in Maine, it’s crucial to establish a streamlined and hassle-free payment infrastructure that allows you to accept payments with ease.

There are several payment processing services available, offering intuitive interfaces and seamless integration options for your website or point-of-sale (POS) system. Prominent choices include Square, Stripe, and PayPal, all of which provide flexibility and straightforward setup, enabling you to customize them to align with your unique business goals.

These payment processors enable you to accept various payment methods, including credit and debit cards, ACH transfers, digital wallets like Apple Pay and Google Pay, and more. By selecting a dependable payment processing service, you can offer your customers the convenience of paying through their preferred methods via a secure platform, ensuring a smooth and secure transaction experience for both you and your valued clients.

Additionally, establishing sales tax compliance in Maine is essential. This involves obtaining a Maine Sales and Use Tax Registration from the Maine Revenue Services, granting you the authority to collect sales tax on taxable goods and services.

With a well-established payment infrastructure in place, your Maine-based business will be fully equipped to serve customers efficiently and generate revenue while adhering to legal obligations.
