How to Start an LLC in Maine (2026 Guide)

Maine’s economy runs on tourism, fishing, forestry, food and a growing number of remote workers and small makers. Forming an LLC costs $175, one of the higher filing fees in New England, and the annual report costs $85, due June 1. Here’s how to set up a Maine LLC and the rules worth knowing before you start.

What a Maine LLC costs

Item	Cost	When
Certificate of Formation	$175	At formation
Annual report	$85	By June 1, from the year after formation
Late annual report	Late penalty	If filed after June 1
Assumed name registration (if using a DBA)	State fee	When registering
Sales tax registration (if selling taxable goods or services)	No fee	Before your first taxable sale

Step 1: Choose your LLC name

The name must include "limited liability company", "limited company", "LLC", "L.L.C.", "LC" or "L.C." and be distinguishable from other names on file. Search the Secretary of State’s business records, then check federal trademarks, domains and social handles with our business name checklist.

To trade under another name, file a statement of intention to transact business under an assumed name with the Secretary of State.

Step 2: Appoint a registered agent

Every Maine LLC needs a registered agent with a physical Maine address. Maine distinguishes between commercial registered agents, which are listed with the state, and noncommercial agents, such as yourself or another individual. Either works; a commercial agent keeps your address off the public record.

Step 3: File the Certificate of Formation

File a Certificate of Formation with the Maine Secretary of State’s Bureau of Corporations and pay $175. Maine has traditionally accepted LLC formation filings by mail, so check the bureau’s website for whether online filing is available when you form, and allow extra time for processing if you file on paper. You’ll include the LLC’s name, registered agent, and the signatures of the people forming it.

Step 4: Create an operating agreement

Maine doesn’t require you to file an operating agreement, but every LLC should have one, covering ownership, management, profit sharing and what happens when members join or leave.

Step 5: Get an EIN and open a bank account

Apply for a free EIN from the IRS online, then open a business bank account using your filed Certificate and EIN. See choosing a business bank account.

Step 6: Register with Maine Revenue Services

Register with Maine Revenue Services for:

• Sales and use tax, if you sell taxable goods or services. Maine’s general rate is 5.5%, with higher rates for prepared food and for lodging and short-term rentals.
• Employer withholding, if you hire.

Employers also register with the Maine Department of Labor for unemployment insurance and the state’s paid leave program.

Step 7: Get licenses and permits

• Contractors. Maine doesn’t license general contractors statewide, but electricians, plumbers and oil and solid fuel technicians need state licenses. Maine also requires written contracts for most home construction and repair jobs above a modest dollar amount, with specific required terms.
• Food businesses. Home cooks generally need a home food manufacturing license from the state agriculture department, a low-cost license that lets you sell many home-made foods. Restaurants and food trucks need health licenses.
• Many professions are licensed by state boards.
• Towns handle zoning, building permits and some local licenses.

Step 8: File your annual report by June 1

Every Maine LLC files an annual report with the Secretary of State by June 1 each year, starting the year after formation. It costs $85. Late reports bring a penalty, and an LLC that keeps failing to file can be administratively dissolved.

How a Maine LLC is taxed

By default, LLC profits pass through to the owners, who pay federal income tax, self-employment tax and Maine’s graduated personal income tax. Multi-member LLCs taxed as partnerships file a Maine partnership return. LLCs electing C corporation status pay Maine corporate income tax. Ask a tax professional which option suits you.

Hiring your first employee in Maine

Beyond the federal steps in our first employee guide, Maine employers generally:

• Register for withholding with Maine Revenue Services and unemployment insurance with the Department of Labor.
• Remit contributions for Maine Paid Family and Medical Leave, the state program that began collecting contributions in 2025.
• Carry workers’ compensation insurance, required for most employers once they have employees.
• Provide earned paid leave under Maine law, which applies to many employers.
• Report new hires to the state.

Seasonal businesses in Maine

Many Maine businesses earn most of their income in summer and early fall: lodging, restaurants, tours, boat rentals, farm stands and craft sales. A few practical points:

• Plan cash flow for the off-season. Set aside money during peak months for winter costs, including the June annual report and insurance renewals.
• Hire early. Seasonal workers are in demand; start recruiting in spring.
• Collect the right sales tax. Prepared food and lodging are taxed at higher rates than general goods.
• Check short-term rental rules, which many Maine towns have tightened.

Our break-even calculator helps you check whether peak-season sales will carry the whole year.

Running a Maine LLC from home or remotely

Maine has attracted many remote workers and home-based makers in recent years. If you’re running your LLC from home:

• Check your town’s zoning and home occupation rules, which vary widely between Maine towns.
• Talk to your insurer, since home policies often exclude business equipment, inventory and customer visits.
• Use a commercial registered agent if you’d rather keep your home address off the public record.
• Keep business and personal finances separate, making expenses and any home-office deduction easy to support.
• If you work for clients in other states, ask an accountant whether those states expect you to register or file taxes there.

Maine rules for other common businesses

Fishing, forestry and agriculture. Commercial fishing, aquaculture, logging and farm businesses often need specific state licenses and permits.

Childcare. Child care facilities and family child care providers are licensed by the state health and human services department. See our home daycare guide.

Mistakes to avoid

• Missing June 1, which falls just as many seasonal businesses get busy.
• Selling home-made food without a home food manufacturing license.
• Doing home construction work without a written contract.
• Charging the general sales tax rate on prepared food or lodging.
• Overlooking paid leave contributions when you hire.
• Letting your registered agent lapse, so state notices and legal papers go astray.

Frequently asked questions

When is my first annual report due? By June 1 of the year after your LLC is formed, and every June 1 after that.

What happens if my LLC is dissolved for a missed report? Maine generally allows reinstatement by filing the missing reports and paying fees and penalties, but your LLC loses good standing in the meantime.

Can I file my Certificate of Formation online? Check the Bureau of Corporations’ website; Maine has traditionally accepted LLC formations by mail.

Can I be my own registered agent? Yes, as a noncommercial registered agent with a physical Maine address.

Is my LLC’s information public? Your LLC’s name and registered agent appear in the Secretary of State’s records.
