How to Start a General Contractor Business in Maine: No State Contractor License, the $3,000 Written Contract Rule, 1/3 Down Payment Cap and $100 to $1,000 Penalties

If you want to start a general contractor business in Maine, the first thing to know is that the state does not issue a general contractor license. Maine has no general contractor, remodeler, roofer, painter or carpenter license, registration, bond or exam at the state level. That makes the search for a general contractor license Maine results somewhat misleading. What Maine does regulate is the contract. Once a residential job involves more than $3,000 in materials or labor, the agreement must be in writing, signed by both sides, and include specific terms. Each violation carries a civil forfeiture of $100 to $1,000.

This guide walks through the steps for choosing a business structure, registering it, handling taxes and insurance, and writing contracts that meet Maine's rules.

Maine Contractor License Requirements: What Actually Applies

Maine's contractor rules work differently from many states. For a general contractor, the requirements break down like this:

• State general contractor license: None. Maine does not license, register, bond or examine general contractors at the state level.
• Town and city licenses: Maine has no general town business license. Municipal officers license named activities under 30-A MRSA 3701, and fees vary widely by town. Ask your municipal office whether any activity you plan to perform needs a local permit or license.
• Trade licenses: Electrical, plumbing and fuel work each keep their own state license through the Department of Professional and Financial Regulation. If you or your subcontractors perform that work, those licenses still apply.
• Home construction contracts: The Home Construction Contracts Act, 10 MRSA ch. 219-A, applies to residential work over the $3,000 threshold.

What You Need Before You Start

• A business name that meets Maine's naming rules, plus a backup choice in case your first pick is taken
• A physical street address in Maine for your business or registered agent (a P.O. box is not enough for a noncommercial registered agent)
• Form MLLC-6 (LLC) or Form MBCA-6 (corporation), downloaded from the Secretary of State site and printed
• Payment for the filing fee, plus the name reservation fee and any expedited fee you choose
• A registered agent who has agreed to serve, or a commercial registered agent listed with the Secretary of State
• A federal Employer Identification Number from the IRS
• Contract templates that include every element required by the Home Construction Contracts Act
• Insurance quotes for general liability and, if you have employees, workers' compensation
• A calendar reminder for June 1 every year

Step-by-Step: Forming and Running a Maine Contractor Business

Step 1: Confirm which licenses apply to your trades

List every type of work you plan to perform. General carpentry, remodeling, roofing and painting do not require a state license. Electrical, plumbing and fuel work do. If you subcontract those trades, confirm that each subcontractor holds the required state license before work begins. Verify requirements for your specific work with the relevant board under the Department of Professional and Financial Regulation.

Then call the city or town office where you will work. Business Answers, a free licensing assistant run by the Department of Economic and Community Development at maine.gov/businessanswers, can also help you identify the permits and licenses that apply to your activities.

Step 2: Pick a business structure

Most contractors choose between a sole proprietorship, an LLC and a corporation. The state filing and fee differ for each:

Structure	Filing	State fee	Where you file
Sole proprietor	Sworn assumed-name certificate, only if you operate under a trade name	Set by each town (not published by the state)	Municipal clerk where the business is carried on
LLC	Certificate of Formation (Form MLLC-6)	$175	Secretary of State
Corporation	Articles of Incorporation (Form MBCA-6)	$145	Secretary of State

An LLC is taxed by default as a pass-through, so members report income on their Maine individual returns at rates of 5.8% to 7.15%. Maine has no LLC franchise tax or separate LLC annual tax. An LLC that elects corporate treatment pays Maine corporate income tax at 3.5% to 8.93%. The right structure depends on your income, your liability exposure and your tax plans, so review it with a CPA.

Step 3: Choose and reserve your name

An LLC name must include "limited liability company," "limited company," "L.L.C.," "LLC," "L.C." or "LC." Search the Secretary of State's business database at apps3.web.maine.gov/nei-sos-icrs/ICRS before you commit to a name. If you need time, reserve it for 120 days on Form MLLC-1 for $20, available at the MLLC-1 form.

Step 4: File your formation documents with the Secretary of State

Maine does not accept online filing of formation documents. Fill in the fillable PDF, print it, and mail or deliver it with payment to the Division of Corporations, UCC and Commissions. The Secretary of State's corporations and LLC pages state a processing time of 2 to 7 business days for corporate filings, but earlier snapshots listed longer times, so confirm the current estimate before you plan a launch date. Expedited handling costs $50 per request for 24 hour service or $100 per request for immediate service, and availability depends on staffing at the time you ask.

Step 5: Appoint a registered agent

Every Maine LLC and corporation must appoint and maintain a registered agent. A noncommercial agent must give a physical street address in Maine, not a P.O. Box. Your formation document must show that the agent has consented to serve. Appointments and changes are filed on Form CLKRA-3 for $35.

Step 6: Register an assumed name if you need one

If you operate under a name other than your legal name or your entity's name, you need an assumed-name filing. Registered entities (LLCs and corporations) file a Statement of Intention to do Business under an Assumed Name on Form ASUM-5 with the Secretary of State for $125. Sole proprietors and general partnerships file a sworn assumed-name certificate with the municipal clerk instead, and the clerk sets that fee.

Step 7: Register for taxes

Get a federal Employer Identification Number from the IRS. Maine's general sales tax rate is 5.5%. Maine's list of taxable services is closed, and it does not include handyman work, but whether your specific contracting services or materials sales are taxable is a question for Maine Revenue Services at maine.gov/revenue. If you hire employees, confirm payroll registration and withholding requirements with the same agency before your first payday.

Step 8: Arrange insurance

Maine does not require a state contractor bond, but customers and general contractors may ask for proof of insurance before they hire you. General liability coverage is the usual starting point. If you have employees, confirm workers' compensation requirements with your insurer or agent. Ask about coverage limits and exclusions before you sign a contract, because gaps in coverage can become your problem on a job site.

Step 9: Check lead paint rules for older homes

If you will renovate homes built before 1978 for compensation, EPA's Renovation, Repair and Painting rule applies. Maine is not an EPA-authorized state for this program, so EPA certifies renovation firms directly. Confirm the current certification steps with EPA before you bid on pre-1978 work.

Step 10: Check door-to-door sales licensing

If you or your staff sell home repair services door to door, a seller needs a Department of Professional and Financial Regulation license. The fee is $30, plus a $21 background check, and the license renews each April 30.

Step 11: Write every residential contract to the statute

This is the step that matters most in Maine. Under the Home Construction Contracts Act, any contract for more than $3,000 in materials or labor to build, remodel or repair a residence of three or fewer living units must meet these rules:

• It must be in writing and signed by both sides, and each side must hold a copy before work starts.
• It must include the names and addresses of both parties, the start and completion dates, the total price, the payment method, and a description of the work.
• The down payment cannot exceed 1/3 of the total price.
• It must include the statutory warranty wording, a dispute-resolution option statement and a change-order statement.
• It must include the Attorney General's consumer-protection addendum under 10 MRSA 1487.
• Electrical, plumbing and heating work is covered by the same rules, so it cannot be left out of a written contract.

Change orders must also be written and signed (10 MRSA 1488). Do not start extra work on a handshake. Each violation carries a civil forfeiture of $100 to $1,000 (10 MRSA 1490). Build these elements into a template once, then fill it in for every job. Have an attorney review the template before you use it.

Step 12: Calendar your annual report

LLCs and corporations file an Annual Report every year, due June 1. The first report is due between January 1 and June 1 of the year after formation. The fee is $85. The LLC form is MLLC-13 and the corporation form is MBCA-13. Missing the deadline can jeopardize your good standing, so set a reminder for May.

Common Mistakes to Avoid

• Assuming no state license means no rules. The contract requirements apply to every residential job over $3,000 even though no contractor license exists.
• Taking a large deposit. A down payment above 1/3 of the total price violates the statute.
• Starting work before both signatures. Each side must hold a signed copy before work begins.
• Handling changes verbally. Change orders must be written and signed.
• Using a registered agent with a P.O. box. Noncommercial agents need a physical street address in Maine.
• Using a trade name without filing. Skipping the ASUM-5 or the municipal certificate can cause problems when you open accounts or sign contracts.
• Hiring unlicensed electricians or plumbers. Those trades keep their own state licenses, and your subcontractors need to hold them.
• Assuming no local rules apply. Towns license named activities by ordinance, so call your municipal office before you advertise.
• Missing the June 1 annual report. The $85 fee is small, but a late or missed report can create avoidable problems.

Expected Results

Completing these steps may put your business in a position to sign contracts in its own name, open a business bank account, and bid residential jobs with clear, enforceable terms. Many contractors also find that a standard written contract template reduces disputes over scope and payment, though results depend on your work, your customers and the quality of your documentation. Nothing in this guide guarantees any outcome, and your results will depend on how carefully you follow each requirement.
