How to Change Your LLC Name in Maine

Changing your LLC name in Maine requires filing Articles of Amendment with the Maine Secretary of State. Whether you’re rebranding, expanding your business scope, or simply want a better name, the process involves specific steps and costs you need to understand upfront.

When You Might Need to Change Your LLC Name

Business owners change their LLC names for various strategic reasons. You might be expanding into new markets and need a name that better reflects your broader services. Perhaps your original name is too similar to another business, creating customer confusion or potential trademark issues.

Some owners discover their name doesn’t work well for marketing or is difficult for customers to remember or spell. Others simply outgrow their original name as their business evolves. Before starting the legal process, make sure your new name aligns with your long-term business goals.

Step 1: Check New Name Availability

Before filing any paperwork, you must verify your desired name is available for use in Maine. The name must be distinguishable from other LLCs and corporations already registered in the state.

You can search Maine’s business name database through the Secretary of State website. This free search shows you registered business names to help avoid conflicts.

Name Requirements

Your new LLC name must:

• Include “Limited Liability Company” or an accepted abbreviation like “LLC”
• Not contain prohibited words without proper licensing
• Be distinguishable from existing registered entities
• Not imply government affiliation without authorization

Optional Name Reservation

If you want to secure your chosen name while preparing other aspects of your name change, Maine allows you to reserve a name for 120 days at a cost of $20. This prevents other businesses from registering your desired name during the reservation period.

Step 2: File Articles of Amendment

Once you’ve confirmed your new name is available, you’ll need to file Articles of Amendment with the Maine Secretary of State. This document officially changes your LLC’s name in the state records.

Filing Details

Maine requires paper filing only for LLC amendments. The state doesn’t offer online filing for these documents, which contributes to the longer processing times compared to other states.

The filing fee for Articles of Amendment is $50. You’ll need to submit:

• Completed Articles of Amendment form
• $50 filing fee
• Credit card payment voucher (Maine’s unique payment system)

Processing Time

Maine takes 35-40 business days to process Articles of Amendment. Unlike many states, Maine doesn’t offer expedited processing options, so plan accordingly if you have time-sensitive business needs.

Step 3: Update Your Records After Approval

Once Maine approves your name change, you’ll need to update your information with various agencies and organizations. This ensures your LLC operates legally under its new name and avoids confusion with customers and vendors.

Update Your EIN with the IRS

Your LLC keeps the same Employer Identification Number (EIN) after a name change, but you must notify the IRS of the change. Send a letter to the IRS stating your old name, new name, EIN, and the effective date of the change. This is sometimes called a Letter 147C.

Mail this notification to the IRS address for your state. Keep a copy for your records, as you may need to provide this documentation to banks or other institutions.

Update Banking and Financial Accounts

Contact your business bank to update your account information. Most banks require documentation of the legal name change, so bring your filed Articles of Amendment from the Maine Secretary of State.

You’ll also need to update:

• Business credit cards
• Payment processing accounts
• Business loans or lines of credit
• Investment accounts

Update Business Licenses and Permits

Review all your business licenses and permits to determine which ones need updates. This typically includes:

• State and local business licenses
• Professional licenses
• Sales tax permits
• Federal licenses (if applicable)
• Industry-specific permits

Contact each issuing agency to understand their process for name changes. Some may require new applications, while others allow simple amendments.

Update Your Operating Agreement

Amend your LLC’s operating agreement to reflect the new name. While Maine doesn’t require operating agreements, if you have one, it should stay current with your legal name.

Have all LLC members sign the amended operating agreement to maintain proper documentation of the change.

Update Marketing Materials and Public Information

Don’t forget to update all customer-facing materials and accounts:

• Website domain and content
• Business cards and letterhead
• Social media accounts
• Google My Business listing
• Directory listings
• Marketing materials
• Email signatures
• Contracts and proposals
