How to Start a Short-Term Rental Business in Maine: Vacation Rentals Need No State License, the 9% Lodging Tax and Why the Town Rules Decide Everything

If you own a house, cottage or camp in Maine and want to rent it to visitors by the night or week, the state will not ask you for a license to do it. The harder work is everything around that: the town ordinance that may or may not allow rentals on your street, the 9% lodging tax you must collect and report, and the annual registration some towns require. Maine short term rental laws are mostly local, so the order you work in matters. This guide walks through the steps in the order we recommend.

Informational content only. This article is not legal, tax or insurance advice. Town rules are changing right now, and several 2025 and 2026 changes are still being applied. Confirm every figure with the agency named before you spend money or sign anything.

What You Need Before You Start

Gather these items before you file anything. Most of them take an afternoon to find, and having them ready keeps the process moving.

• The property address, the owner name as it appears on the deed, and the parcel or tax map number from your town assessor
• Your lease, or your HOA or condo declarations if the property is in a common-interest community, because private rules can prohibit rentals even where the town allows them
• A unit count and a simple floor plan, since many towns price registration by the number of units
• A federal EIN if you plan to form an entity, or your Social Security number if you will operate as a sole proprietor
• A Maine street address for a registered agent if you form an LLC or corporation, because a P.O. Box will not work for a noncommercial agent
• A business name checked in the Secretary of State database at https://apps3.web.maine.gov/nei-sos-icrs/ICRS
• A printer and a payment method, because Maine formation forms are filed on paper
• A calendar for the deadlines listed near the end of this guide

Step 1: Confirm You Are Running a Vacation Rental

Maine requires no state license for vacation rentals under 22 MRSA 2501. That is why most owners never deal with a state licensing agency. The state lodging license administered by the Department of Health and Human Services Health Inspection Program applies to bed and breakfast and inn style operations, not to a standard vacation rental where guests have the home to themselves.

Be honest with yourself about which model you are running. If you plan to serve meals, share living space with guests or operate something closer to a bed and breakfast, ask the Health Inspection Program before you list the property. Serving food to guests can raise a separate licensing question, so do not assume breakfast is a minor detail.

Step 2: Check the Town Before Anything Else

Towns may regulate short-term rentals by ordinance under 30-A MRSA 4364-C(2), so the local rule usually decides whether you can operate at all. There is no single Maine answer, and the rules vary widely. Examples as of October 2026 include:

• Portland: Registration is due annually by January 1, with fees based on unit count. Ask the city whether a citywide cap affects your property.
• Bar Harbor: Chapter 174, effective December 18, 2025, requires annual registration at $275. It also creates a VR-2 category that is capped and operates with a waitlist, so a permit may not be available when you want it.
• Bangor: Non-hosted rentals are capped at 1% of dwelling units.
• York: Voters rejected a proposed rental ordinance in May 2024. Check with the town for what currently applies rather than assuming the vote settled the question.

If your property sits in the unorganized territory, the Land Use Planning Commission requires a free online notice for short-term rentals under a rule effective January 12, 2026. Separately, two 2025 housing laws, PL 2025 c. 385 and PL 2025 c. 733, change local zoning. Ask the municipal office whether those changes affect your zone. Our town-by-town table of short-term rental rules is a useful starting point, but the municipal office is the final word because local ordinances change.

Step 3: Choose Your Business Structure and File It Correctly

Maine does not require a particular structure for a rental. Your choice affects liability, taxes and paperwork, so this is a good point to ask a CPA or attorney if the property is valuable or you have partners.

• Sole proprietorship: No state formation filing is required. If you operate under a name other than your own, you file a sworn assumed-name certificate with the clerk of the city or town where the business is carried on, under 31 MRSA 1. Municipal fees are set by each town, so call the clerk to confirm the amount.
• LLC: Form MLLC-6, the Certificate of Formation, is filed under 31 MRSA 1531 with a $175 filing fee. Maine does not accept online formation filings, so print the fillable PDF and mail it or deliver it with payment. The name must include words such as limited liability company, limited company, LLC, L.L.C., LC or L.C. You can reserve a name for 120 days on Form MLLC-1 for $20.
• Corporation: Form MBCA-6, the Articles of Incorporation, is filed under Title 13-C with a $145 filing fee. Most small rental owners do not need this structure.

For any LLC or corporation, you must appoint a registered agent and keep that appointment current. The agent can be a commercial registered agent listed with the Secretary of State or a noncommercial agent with a physical Maine street address. Changes are filed on Form CLKRA-3 for $35.

Expedited handling is available. Twenty-four hour service costs $50 per request, and immediate service, completed when the request is made, costs $100 per request. Availability depends on staffing, and the Bureau notes delays during high volume, so do not build your launch date around an expedited filing.

If you operate under a trade name as an LLC or corporation, file a Statement of Intention to do Business under an Assumed Name (Form ASUM-5) with the Secretary of State for $125. The form is available from the Secretary of State at https://www.maine.gov/sos/corporations-commissions.

Step 4: Register for Maine Lodging Tax

Rental of living quarters is taxed at 9% under 36 MRSA 1811. This is a separate rate from the 5.5% general state sales tax, and it applies to your nightly or weekly rent.

Anyone who manages or operates a rental on a casual basis, or who collects its rents, must register with Maine Revenue Services under 36 MRSA 1754-B(1-B)(E) and (F). Transient rental platforms must also register. Do not assume the booking platform handles everything. Contact Maine Revenue Services and ask whether the platform collects the tax on your stays and whether you still need to register yourself. Get the answer in writing if you can, and keep it with your records.

Also note that other rates apply to other sales. If you sell prepared food, such as breakfast you charge for separately, the 8% rate on prepared food may apply. Confirm the treatment of any extras with Maine Revenue Services before you publish your pricing.

Step 5: Register With Your Town

Once you know the local rule, complete the town registration. Expect to provide the property address, owner contact information, unit count, a local contact who can respond to complaints, and the fee the town sets. Some towns also require safety items, occupancy limits or parking plans. Ask the municipal office for its application and its current fee schedule, then get written confirmation of your approval or registration number.

Step 6: Check Trade and Activity Licenses

Maine has no general statewide business license and no general town license. Registering an entity or an assumed name is a filing, not a license. Licensing is by activity. Municipal officers license named activities by ordinance, and fees vary by town. Use the free Business Answers assistant at https://maine.gov/businessanswers to identify state requirements for your specific activities.

If you renovate, repair or hire contractors, check with the Department of Professional and Financial Regulation boards about which trade licenses apply. Maine has no HVAC license and no general contractor license, but some trades are licensed by state boards, so confirm before you hire or do the work yourself.

Step 7: Review Insurance Before You Accept Bookings

Insurance is the step owners most often skip. Many standard homeowners policies limit or exclude business activity, and a guest injury or property loss may fall outside coverage. Ask your insurance agent in writing whether your policy covers short-term rental activity, and ask about liability coverage specifically. Insurance costs vary widely, so get quotes rather than estimates from this article.

Step 8: Plan for Maine Income Tax

An LLC is taxed by default as a pass-through, so members report rental income on Maine individual income tax returns at graduated rates of 5.8% to 7.15%. An LLC that elects corporate treatment pays Maine corporate income tax at 3.5% to 8.93%. Maine has no LLC franchise tax and no separate LLC annual tax. The only recurring state filing charge for an LLC is the $85 annual report fee. Work with a CPA on depreciation, deductible expenses and whether an election makes sense for your situation.

Step 9: Build a Deadline Calendar

Missed deadlines cause more problems than most filing errors. Put these on your calendar when you start:

1. January 1: Portland registration is due each year if your property is in Portland.
2. January 1 to June 1 in the year after formation: The first LLC annual report window. Your first report is due in that window.
3. June 1 each year: LLC annual report, Form MLLC-13, for $85, filed through the Annual Report Online system at https://apps1.web.maine.gov/cgi-bin/online/aro/index.pl.
4. Your town's annual deadline: Confirm the date with the municipal office, because it varies.
5. Lodging tax filing: Confirm your filing frequency and due dates with Maine Revenue Services after registration.

Common Mistakes to Avoid

• Listing before checking zoning. A booking you accept before the town approves your registration can leave you refunding guests and absorbing the cost.
• Treating no state license as no state obligations. The lodging tax registration applies even though no state license does.
• Assuming the platform collects everything. Ask Maine Revenue Services directly and keep the answer on file.
• Using a trade name without filing. An LLC operating under a different name needs an ASUM-5, and an individual needs a sworn certificate with the municipal clerk.
• Naming a P.O. Box as your registered agent address. A noncommercial agent needs a physical street address in Maine.
• Relying on current rules forever. Towns can change ordinances, and the 2025 housing laws are changing zoning. Ask each year whether your status has changed.
• Ignoring HOA or lease terms. A town permit does not override a private restriction.
• Mailing forms without the correct payment. Maine formation filings are paper filings, so a wrong or missing fee can delay everything.

Expected Results

Completing these steps may help you operate on firm footing and avoid the most common enforcement and tax problems. It may also give you clear records if a town, the state or a platform asks questions later. Revenue depends on location, season, pricing, occupancy and your costs, and nothing in this guide is a projection of income. Many owners find that the first season is slower than they expect, so plan your budget for a slow start.
