In Maine, you have three pathways to register your business name. You can establish it as an LLC or Corporation to have your business be a separate entity or you can opt for a DBA (officially recognized as an Assumed Name) if you’re a sole proprietor or part of a general partnership. If you want additional protection against people using your business name across the country, you can also opt to file a federal trademark with the USPTO.

Be sure to have your business name registered before completing the other registrations you’ll need to be legally compliant in Maine, like:

  • Creating your Maine Tax Portal account to register for Sales & Use Tax and/or income tax withholding with Maine Revenue Services
  • Acquiring mandatory state, municipal, and county licenses and permits
  • Obtaining an IRS Tax ID Number (EIN)
  • Setting up a dedicated business bank account

How much does it cost to Register a Business Name in Maine?

The cost to register a Maine business name varies depending on the type of registration:

  • Maine LLC cost: $175
  • Maine Corporation cost: $145
  • Maine DBA cost: $10

1. Check Business Name Availability

Before registering your Maine business name, you’ll want to confirm that your business name is available. Even if the exact name isn’t in use, you should also make sure that it isn’t too similar to other names in use. If another business is using your desired business name, you’ll need to come up with another name. To be thorough, you should include three types of searches:

Start your Maine business name search with the help of professionals.

Trademark Search

Federal trademarks are the highest registration level for a business name, so you should start there. Trademarks registered with the U.S. Patent and Trademark Office (USPTO) supersede state and local level registrations, so verifying the name you want isn’t trademarked is crucial. If it is trademarked, you’ll need to go back to square one and come up with a new name.

Visit the Trademark Electronic Search System (TESS) page to search the USPTO database directly. If you find the results overwhelming or difficult to understand, you can also use the Free Trademark Search available from Trademark Engine.

Maine Business Name Search

You can move on to verifying that your business name is available to use in Maine after you’re sure it hasn’t been trademarked. To do a Maine business name search, use the Maine Corporate Name Search to search the database of business names registered in the state.

You’ll want to search for your exact name and do some searches that include partial matches of your business name or use wildcard characters. This ensures that there aren’t businesses with very similar names that don’t appear from an exact name search. One of the number one reasons a business name registration is rejected is the name being too similar to an existing business.

Pro Tip: If you do a search and see your name is available but was used in the past, you should strongly consider choosing a new name. Using a previously registered name can cause issues with obtaining an EIN.

Since most businesses choose to get an EIN, it will be highly likely that an EIN has been issued with that name. If an EIN was previously issued under that business name, the IRS EIN system cannot issue an EIN online and will return a 101 reference error. When an EIN application gets a 101 error, the only way to get an EIN issued under that name is to call the IRS and fax them a copy of your business registration paperwork. So, do yourself a favor and pick a new name unless you absolutely need to use that name.

Website Domain Search

At this stage, you should have a good idea that your name is available to use in Maine and no trademark issues, so it’s time to ensure your domain name is available. For almost every business, it’s worth it to register a business domain name to prevent competitors from taking your domain name. If you want a professional business email address, you’ll also need to register your domain.

Domain Name and Business Email

You can use Namecheap to verify if your domain name is available. They also offer a business email service that’s free to try for the first 60 days when you purchase a domain.

2. Choose a Business Structure

Before you can file a business name registration in Maine, you need to decide on the structure your business will use. The specific registration requirements and type of filing will depend on if your business is an LLC, corporation, sole proprietorship, or general partnership. Each of these business structures has its own advantages and disadvantages. It impacts important aspects of your business, including the owners’ legal liability, how taxes are paid, and how easy it can be to get loans. Below is a comparison and explanation of each structure. If you require additional guidance, be sure to check out our guide, How to Choose your Business Structure, where we cover this decision in more detail.

Recommended Business Structure:

Starting an LLC is ideal for most new businesses because they can have any number of owners and have unique benefits. LLCs provide liability protection that isn’t available to sole proprietors and general partnerships with pass-through taxation that corporations lack.

For example, if your full name is “Kelly Martin” and you run an Italian restaurant, you won’t need to register the name “Kelly Martin’s Italiana,” but, if you want to use a branded name like “Cucina Amore Italiana,” you’d need Maine (DBA).

However, if they opt for a creative business identity like “Sweet Harmony Confections,” they must file an Assumed Name (DBA) name.

The rules for a Maine Assumed Name (DBAs) are not quite as strict as they are for LLCs or Corporations, however there are still restrictions. Mainly, your DBA can’t include designators used for legal entities like “LLC” or “Inc” in the Assumed Name. DBAs also can’t contain prohibited words or words that imply association with government entities.

Remember, if you’re running a business using any name other than your legal name in Maine, registering a DBA is necessary. Failure to file an Assumed Name Certificate is punished by a fine of $5 per day the business is delinquent.

4. File a Trademark (Optional)

Trademark registration can provide increased security for your business identity. A trademark is like a safeguard for your Maine business name, allowing you complete control over your brand. Unlike state-level registrations, trademarks offer federal-level protection that extends nationwide.

You can apply for a trademark online, but be aware that the process can be complex and time-consuming. Evaluation of a trademark application by a USPTO examining attorney takes approximately 7-9 months. Given the intricacies involved in the process, thoroughly preparing your initial application with great attention to detail is essential.

To streamline the trademark registration journey, seek guidance from a qualified attorney or specialized trademark filing service. Their expertise can save you time and simplify the complexities associated with application submission and follow-ups.
