LLC requirements vary state by state, so it’s important that you are well-versed in Maine laws before proceeding. Generally, it comes down to these steps:
Pick a unique name for your LLC. The first step is selecting an LLC name. That may sound simple, but it’s important to consider a few factors. You need a name that’s clear and identifiable for your Maine business.
Maine state law requires that your business name include one of the following designators in its name indicating that the company is an LLC:
Be careful about names that can sound questionable in nature. Maine forbids using obscene language, as well as anything that promotes illegal activity. You also can’t use a name that makes a false connection to a public entity.
If you’re forming a Maine PLLC, you might have extra naming requirements to uphold. While you can use the same designators as a regular LLC, you will need to check your industry’s rules for naming a business. Every PLLC needs a name that complies with industry requirements. Each regulatory board can have different requirements for a business name, so please consult with them to help ensure you don’t overlook any name requirements.
Before finalizing anything, though, you need to research whether the name you want is available. You can’t have the same name as any other business in Maine.
If you find a name you like but aren’t yet ready to file your Articles of Organization, Maine allows you to reserve a business name for 120 days for a $20 filing fee. This reservation can’t be renewed.
When you’re coming up with a business name, it’s wise to consider whether you can secure a matching domain name so that your future website can be easily found online.
If you plan on naming your LLC one thing but want to do business with another name, you will need a DBA name, known in Maine as an “assumed name.” For this, you’ll need to file a Statement of Intention to Do Business Under an Assumed or Fictitious Name. There is a filing fee involved for an assumed name filing. Each assumed name filing costs $125 for LLCs.
Note that the Pine Tree State (unlike most other states) differentiates between an assumed name and a “fictitious name.” Here a fictitious name is a name adopted by a foreign (out-of-state) corporation authorized to transact business in Maine because its real name is unavailable. There’s a fee involved for a fictitious name filing.
To make sure you’re entirely in the clear with your business name, visit the United States Patent and Trademark Office website. There you can find out whether your business name or logo is federally trademarked.
Trademarks can also happen at the state level. To find out if your desired business name is already trademarked in Maine and/or apply for a trademark of your own, go to the Maine Secretary of State website and run a Corporate Name Search.
Choose a registered agent. A registered agent is a person or business entity designated to receive legal documents and certain correspondence from the Secretary of State on behalf of your business. Basically, an agent will be the designated recipient of legal summons if someone ever takes your business to court.
Because legal proceedings are quite important, Maine requires a registered agent to be listed and kept current.
To serve as a registered agent in Maine, the following criteria must be met. A Maine registered agent must:
Under those criteria, you can technically serve as your own agent, appoint a friend or family member, or hire a registered agent service. It’s generally recommended to appoint a registered agent service.
There are several reasons you should appoint a registered agent service.
File the paperwork to officially form your LLC. Now that you have your name and registered agent, it’s time to file your Certificate of Formation. To complete the application, you will need the following information:
The application also requires a cover letter that includes:
To file your application, you must pay a filing fee of $178. Expedited filing is an additional cost for 24-hour processing and immediate processing. All applications must be delivered by mail or in person. Maine is unusual in that it has no online filing option.
To mail in your Certificate of Formation, send it to:
Department of the Secretary of State
Division of Corporations, UCC and Commissions
101 State House Station
Augusta, ME 04333-0101
Write an operating agreement. Unlike most states, Maine requires LLCs to have an operating agreement, which it calls an LLC Agreement. According to the statute, you can create the agreement before or after filing your Certificate of Formation, but you must create one.
Even if Maine didn’t require an LLC operating agreement, we’d still recommend writing one. That’s because a Maine operating agreement presents a lot of benefits:
Your operating agreement, once complete, should be kept with your business filings.
Get an EIN. The fifth step is to apply for an Employer Identification Number (EIN), also called a Tax ID Number. You can apply for an EIN through the IRS website or by mailing Form SS-4.
Your business EIN works like a Social Security number for your business and is also referred to as a Federal Tax Identification Number. Among other things, you need an EIN if you have multiple LLC members or if you plan to hire employees. Still, even if neither of those applies to your business, you should consider obtaining an EIN, anyway. Most banks require an EIN to open a business bank account.
Your Maine LLC may also need to pay a variety of state and local taxes. These include taxes that are payable to the Maine government, like sales tax. If you plan to sell products or services taxable in Maine, you will need to file an Application for Tax Registration with the Maine Revenue Services.
For state income taxes, your LLC will be taxed the same way as you elected to have it taxed by the federal government. If you have your LLC taxed as a corporation at the federal level, you’ll also need to pay Maine’s corporate income tax.
To learn more about your tax responsibilities, contact the Maine Revenue Services and your local tax authorities. We also advise consulting a tax professional.
There’s a very good chance that your Maine LLC will need at least one license or permit. But it’s not quite as simple as saying, “File this form with the Maine Secretary of State.” For this step, you’ll need to dig in and do some research.
For starters, some LLCs need to get federal licenses. For example, suppose you’re going to craft the perfect brandy or cinnamon whiskey. In that case, you’d need to get a license from the Alcohol and Tobacco Tax and Trade Bureau since you’d be manufacturing and selling alcohol. Meanwhile, businesses in aviation would need to get a license from the Federal Aviation Administration. If your LLC involves a heavily regulated activity, there’s a good chance you’ll need a federal license, but it’s your responsibility to research and know for sure.
Next, you’ll have to check state-level licenses. Unlike some states, Maine doesn’t administer a general business license at the state level; that requirement comes in at the town or city level. That said, there are other state-level requirements to uphold. For example, if you’re going to be selling tangible products or offering a taxable service, then you’ll need to complete the state’s sales tax registration process.
You may also need to get local licenses from your city or county. These requirements vary a lot from one municipality to another. For example, Lewiston has over 40 different categories of business licenses, from bowling alleys to mobile home parks, and more. Augusta has its own list of business types that need a license. It’s crucial that you research your area’s unique requirements.
You may also need to get zoning permits for your location. Similarly, if you’re working out of your home, you may be required to get a home occupation permit. Ultimately, it’s your responsibility to research your local requirements.
Last but not least, you’ll need to research licenses related to your industry or profession. Many skilled trades, such as cosmetology, HVAC repair, or electrical work, all require professional licenses. Meanwhile, other professionals like doctors, nurses, therapists, and lawyers all need licenses from their profession’s regulatory board. And the list could go on.
Long story short: you’ll need to do plenty of research to ensure you get all of the licenses that apply to your unique business — your unique industry, services, and business location.
Licensing is extremely important for a PLLC in Maine. It’s your responsibility to ensure that everyone offering your company’s professional service, including your employees, is appropriately licensed. But professional licensing requirements don’t overwrite your other state and local license requirements; you’ll still need to get those licenses, too.
Once your Maine LLC is established, it’s crucial to undertake a few more steps to ensure smooth operation and compliance.
Implement an effective accounting system to manage your finances, track expenses, and prepare for taxes. It’s essential for maintaining financial health and compliance.
Once you’ve secured an EIN, you’ll be able to open a business bank account. Having separate accounts for your business and your personal banking is critical for sorting out your finances at tax time and helps you avoid commingling funds. Commingling funds can not only make your taxes more difficult, but it could also be used against you if someone takes you to court to challenge whether you and your LLC are truly separate entities.
Stay updated on ongoing legal requirements, including tax obligations and any changes in business laws, to ensure your LLC’s compliance in Maine. These obligations are subject to change at any time. That’s why a lot of entrepreneurs have a regular consultation with an attorney or tax professional to make it easier to stay informed.
If you accidentally made a mistake on your Certificate of Formation, don’t worry; you can correct them. The process involves filing the Certificate of Amendment form (available on the Maine Secretary of State website). Fill out the form with the correct information, clearly indicating the errors being corrected. After completing the form, submit it along with the required $50 filing fee. It’s important to double-check the form before submission to ensure all corrections are accurate.
Timely correction of these details is crucial for maintaining accurate public records and ensuring your LLC’s compliance with state regulations.
In Maine, various types of LLCs cater to different business needs and structures, each with unique characteristics.
A single-member LLC is tailored for individual business owners. It combines the simplicity of a sole proprietorship with the liability protection of an LLC, making it ideal for solo entrepreneurs in Maine.
A multi-member LLC is very similar to a single-member LLC in its structure, but instead of one owner, there are two or more. A multi-member LLC offers a flexible structure, allowing for shared decision-making and responsibility while maintaining the benefits of an LLC.
A foreign LLC is an LLC that was originally formed in another state but operates in Maine. To compliantly operate in the state, registering for authority to transact business is required.
Specifically for professionals who require state licensing (like doctors or lawyers), a professional LLC adheres to both the standard regulations of an LLC and the additional requirements of professional services. Members of a Maine professional limited liability company must be licensed in the profession the company represents.
No. As of this writing, Maine doesn’t allow Series LLCs. A Series LLC is set up with one primary LLC that acts as an umbrella over several other LLCs in order to shield the LLCs from each other’s liabilities.
Dissolving an LLC in Maine is a multi-step process that requires careful attention. First, refer to your LLC’s operating agreement for any specified dissolution procedures. You should follow those guidelines when getting consent for the dissolution from your members. After that, you’ll need to file a Certificate of Cancellation with the Secretary of State. This document officially notifies the state of your LLC’s termination.
As part of this process, you’ll also have to ensure that all debts and liabilities of the LLC are settled and that any remaining assets are distributed among the members according to the LLC’s operating agreement or state law. Additionally, it’s vital to address any final tax obligations. This includes filing a final tax return and paying any outstanding taxes. Properly concluding all business and tax affairs is essential to avoid legal complications or financial liabilities after dissolution.
