Pro Tip
Write a Business Plan
A written business plan is required by most banks and all SBA lenders before they will approve financing. Include at minimum your revenue model, target customer, startup costs, and 12-month cash flow projections.
Use our business plan guide to build a lean plan in a weekend. Keep it under 15 pages and focus on the numbers, not the narrative.
Pro Tip
Choose Your Business Structure in Maine
Most founders in Maine choose an LLC because it combines personal liability protection with pass-through taxation. Filing a Certificate of Formation costs $175 at the Maine Secretary of State.
The four main structures are sole proprietorship, LLC, S-Corp, and C-Corp. See the full comparison below before deciding, or read our Maine LLC formation guide for a detailed walkthrough.
Pro Tip
Business Structure Comparison — Maine
Full comparison guide| Structure | Maine Filing Cost | Personal Liability | How You're Taxed | Best For |
|---|---|---|---|---|
| Sole Proprietorship | $125 (DBA) | ❌ None | Personal income tax. No separate return. | Freelancers, consultants, side hustles testing an idea with no employees. |
| LLC Most Common | $175 online | ✅ Personal assets protected | Pass-through by default. Elect S-Corp when profitable. | Most small businesses. Best balance of liability protection, flexibility, and tax options. |
| S-Corporation | ~$175 + IRS election | ✅ Personal assets protected | Pass-through. Owners pay themselves a salary — can reduce self-employment tax. | Profitable businesses (typically $50K+ net) where payroll tax savings justify the complexity. |
| C-Corporation | $145 | ✅ Personal assets protected | Corporate tax rate (21% federal). Double taxation on dividends. | Startups planning to raise VC funding, issue stock options, or eventually go public. |
| General Partnership | Free / No State Filing | ❌ None — all partners personally liable | Pass-through. Each partner reports share on personal return. | Two or more owners who trust each other and don't need liability protection. |
Which should you choose? Most first-time founders in Maine pick an LLC — it protects your personal assets without the complexity of a corporation. If you're not sure, consult a CPA or business attorney before filing. Read the full Maine LLC guide →
Choose and Register Your Business Name
Your business name must be distinguishable from any entity already on file with the Maine Secretary of State. Search the Maine corporate name database to confirm availability before filing.
If you form an LLC, the name must include "LLC" or "Limited Liability Company" as a designator. You can reserve a name for 120 days for a $20 fee if you are not ready to file immediately.
Pro Tip
Check Maine Business Name Availability
Search the official Maine Secretary of State, Bureau of Corporations, Elections & Commissions database before you file.
Register Your Business with the State of Maine
File your Certificate of Formation with the Maine Secretary of State by mail for $175 (plus a $3 copy fee). Maine does not currently accept online LLC formation filings, so plan for 10 to 15 business days of standard processing.
Pay an extra $50 for 24-hour expedited processing if you need faster turnaround. You will receive a stamped Certificate of Formation as proof your entity exists.
A registered agent with a physical Maine address is required for every LLC. See our Maine registered agent guide for affordable options.
Pro Tip
Important
File Online with Maine Secretary of State, Bureau of Corporations, Elections & Commissions
Official Maine business registration portal. Standard processing: 10-15 business days.
Get Your Federal EIN from the IRS
Apply for your Employer Identification Number (EIN) for free at the IRS EIN portal. The online application takes about 10 minutes and you receive your EIN immediately.
You need an EIN to open a business bank account, file federal taxes, and hire employees. Even single-member LLCs benefit from having one to keep their Social Security number off business documents.
Pro Tip
Get Your Maine Licenses and Permits
Requirements vary by industry, but most Maine businesses need some combination of the following:
- Sales Tax Registration (required if selling taxable goods or services; register free at Maine Revenue Services)
- Local Business Permits (Maine has no general state business license, but most municipalities require a local occupational or business permit)
- Professional License (required for contractors, healthcare providers, real estate agents, and other regulated professions; check the Maine Office of Professional and Occupational Regulation)
- Employer Registration (required before hiring; register with the Maine Department of Labor for unemployment insurance)
- Food Establishment License (required for restaurants, food trucks, and food manufacturers from the Maine Department of Health and Human Services)
Pro Tip
Important
Open a Business Bank Account
Bring your EIN confirmation, Certificate of Formation, government-issued ID, and LLC operating agreement to the bank. Keeping business and personal funds in separate accounts is essential for maintaining your LLC's liability protection.
Compare account options in our best business bank accounts guide. Many online banks offer free business checking with no minimum balance, which works well for early-stage startups.
Pro Tip
Set Up Accounting and Understand Maine Taxes
Maine has a graduated income tax with rates from 5.8% to 7.15% depending on your taxable income. LLC profits pass through to your personal return, so set aside approximately 25% to 35% of net income for combined state and federal estimated quarterly taxes.
Register with Maine Revenue Services to file and pay state taxes. Estimated payments are due quarterly (April 15, June 15, September 15, and January 15).
Use cloud accounting software from day one. Check our best accounting software guide for affordable options that automate invoicing and tax categorization.
Pro Tip
Get Business Insurance in Maine
Maine requires workers' compensation insurance for all businesses with one or more employees. Even if you have no employees, general liability insurance protects your LLC from lawsuits and property damage claims.
Compare quotes from multiple carriers using our best business insurance guide. Most Maine small businesses pay between $500 and $2,000 per year for a basic general liability policy.
Pro Tip
Important
Build Your Online Presence
Claim your free Google Business Profile before anything else. It takes 15 minutes and puts your business on Google Maps and local search results immediately.
Build a simple website using one of the platforms in our best website builders guide. Even a single-page site with your services, location, and contact info builds credibility with Maine customers.
Pro Tip
Stay Compliant After Forming Your Maine Business
After forming, keep your Maine business in good standing by meeting these requirements:
- Annual Report (due June 1 every year, fee: $85 for domestic LLCs; file through the Maine Secretary of State)
- State Tax Filings (file your Maine income tax return annually by April 15; pay quarterly estimates to Maine Revenue Services)
- Registered Agent (maintain a registered agent with a physical Maine address at all times)
- Business Licenses (renew any local permits and professional licenses on their annual renewal dates)
- Sales Tax Returns (file monthly, quarterly, or annually depending on your sales volume)
Missing the June 1 annual report deadline results in late fees and potential administrative dissolution. Track all deadlines with Geekdiys's compliance calendar.

Maine Business Background & Context
State-specific data to help you plan — taxes, economy, funding, and what to expect after you form.
Maine's 142,000 small businesses make up 99.2% of all businesses in the state and employ roughly 58% of the private workforce. That concentration means local communities actively support small business owners.
The state has no franchise tax and no gross receipts tax, reducing the annual compliance burden on small businesses. Combined with relatively low commercial rent outside Portland, operating costs stay manageable.
Maine's quality of life consistently ranks in the top 15 nationally, which helps attract and retain talent. The state also offers targeted incentives for businesses in rural areas through the Maine Department of Economic and Community Development.
Tourism brings over $6 billion in visitor spending each year, creating opportunities well beyond the hospitality sector. From craft food production to outdoor recreation gear, seasonal demand fuels year-round businesses.
Maine's tight-knit business community and strong "buy local" culture give new businesses a real advantage. Customers here actively prefer to spend money with local owners over national chains.
Maine Business Climate
Maine's top individual income tax rate of 7.15% is higher than the national average, but the state offsets that with no franchise tax and no inventory tax. The 5.5% sales tax rate is below the national average of 6.6%.
The state ranked 37th in the Tax Foundation's 2024 State Business Tax Climate Index. Regulatory requirements are moderate, with straightforward formation paperwork and no general state business license mandate.
Maine's unemployment rate has remained below 4% in recent years, reflecting a stable labor market. The Maine DECD offers tax increment financing (TIF) and Pine Tree Development Zone credits for qualifying businesses.
Broadband expansion initiatives are improving connectivity in rural areas, making remote and online businesses more viable across the state. The state has invested over $200 million in broadband infrastructure since 2020.
These industries drive Maine's economy and represent strong opportunities for new businesses:
- Tourism and Hospitality (over $6 billion in annual visitor spending; supports roughly 110,000 jobs)
- Healthcare and Biomedical (one of the fastest-growing sectors, adding jobs at nearly 3% annually)
- Fishing, Aquaculture, and Agriculture (Maine produces 90% of the U.S. lobster harvest and has a growing craft food movement)
- Forest Products and Manufacturing (wood products contribute over $8 billion to the state economy)
- Technology and Clean Energy (offshore wind and solar projects are creating new contractor and service opportunities)
- Craft Beverages and Food Production (Maine has over 150 craft breweries and a nationally recognized farm-to-table scene)
Maine taxes individual income at graduated rates of 5.8%, 6.75%, and 7.15%. LLC profits pass through to your personal return, so your tax rate depends on total taxable income.
The state sales tax rate is 5.5% on most tangible goods and some services. Prepared food and short-term lodging are taxed at higher rates of 8% and 9% respectively.
Maine has no franchise tax and no gross receipts tax. That means your LLC only pays taxes on actual profits, not on total revenue.
Corporate income tax in Maine ranges from 3.5% to 8.93% for C-Corps. S-Corps and LLCs avoid corporate-level tax through pass-through treatment.
Register with Maine Revenue Services for all state tax accounts, including income tax withholding if you have employees. Property taxes are assessed locally and vary widely by municipality, averaging around $13.10 per $1,000 of assessed value statewide.
Maine's cost of living index is approximately 103 (compared to the national average of 100), with Portland being the most expensive market. Rural areas and smaller cities like Bangor and Lewiston offer significantly lower commercial rents and housing costs.
The state minimum wage is $14.15 per hour as of 2026, which is above the federal minimum. Average commercial rent ranges from $12 to $22 per square foot depending on location and property type.
Energy costs in Maine are above the national average, with commercial electricity averaging around $0.17 per kWh. Businesses should factor heating costs into their budget, especially for brick-and-mortar locations in northern Maine.
The Maine SBDC offers free business advising at locations statewide. Their advisors help with business plans, financial projections, and loan application preparation at no cost.
The SBA Maine District Office in Augusta connects businesses with SBA-backed loan programs. SBA 7(a) loans provide up to $5 million in financing with competitive rates for qualifying small businesses.
The Finance Authority of Maine (FAME) offers direct loans, loan insurance, and equity capital for Maine businesses. FAME's programs include microloans starting at $5,000 for early-stage companies.
The Maine Technology Institute (MTI) awards grants of up to $75,000 for technology-based startups and innovation projects. Apply through their competitive grant rounds announced on the MTI website.
In your first 30 days, open your business bank account, register for Maine state taxes at Maine Revenue Services, and obtain any required local permits. If you plan to hire, register for unemployment insurance with the Maine Department of Labor and get workers' comp insurance before your first employee starts.
Between days 30 and 60, set up your accounting system, claim your Google Business Profile, and launch at least a basic website. File your first estimated tax payment by the next quarterly deadline (April 15, June 15, September 15, or January 15).
By day 90, mark June 1 on your calendar for your first annual report ($85). Review your insurance coverage and adjust if your operations have changed since formation.

I have three staff at a small bakery in Brunswick and a payroll deduction turned up on my first pay run that I had not budgeted for. What is it, and does it apply to me as the owner too?
Jennifer PayneGeekdiys team
Director of Entrepreneurial Strategy · September 3, 2026
Maine runs a paid family and medical leave programme funded by a payroll contribution, and it starts with your first employee, so a three person bakery is fully inside it. Size decides who pays rather than whether you pay. Above a headcount threshold the contribution is split between you and the worker. Below it the total is smaller and an employer is allowed to withhold the whole thing from wages rather than contributing. Both are set as a percentage of pay, so it scales with your payroll. As the owner you are outside it unless you choose to opt in, which self employed people can do at their own rate, and doing so is what makes you eligible to claim later.

trying to find out how to get a business licence in maine and every page including this one basically says there is not one. so what is the thing i keep being asked for. two customers have now asked whether i am licensed and i sell handmade furniture
Jennifer PayneGeekdiys team
Director of Entrepreneurial Strategy · August 22, 2026
There genuinely is not one, and what your customers are asking about is something else. Maine issues no general business licence, so there is no certificate covering a furniture maker as such. Three things fill the gap. Some trades and professions are licensed individually by state boards, and furniture making is not one of them. Your town may want a local permit, particularly for a workshop with machinery or for anything customer facing, so ask the municipal clerk. And if you sell to the public you need a sales tax registration with Maine Revenue Services, which is free and is the closest thing you have to a document to wave at people. Two customers asking usually means they want proof of insurance rather than a licence, so worth asking them exactly what they need.

Everyone in my line of work keeps telling me to become an S corp and nobody explains what Maine wants for it. Do I file something with the state as well as the federal election, and does Maine actually tax it differently, or is the whole benefit federal?
Jennifer PayneGeekdiys team
Director of Entrepreneurial Strategy · August 13, 2026
Nothing extra goes to Maine. The state follows your federal election, so once the IRS accepts it Maine treats the company the same way with no separate state form. The benefit is federal too. It is about splitting your income between a wage and a distribution so that part of it escapes self employment tax, and that split is a federal calculation. Maine adds one thing worth knowing about rather than a tax. If any owner lives outside Maine, the business generally has to withhold Maine tax on their share of the income and file for it, which is real paperwork for a company with an out of state partner. And the wage side means running actual payroll, which costs money, so the election only pays off above a certain level of profit.
