Tax system of Maine
Income Tax
Maine uses a progressive personal income tax with rates ranging from 5.8% to 7.15%. All major categories of income are subject to tax — wages, business profits, rental income, dividends, and capital gains. Tax deductions and credits are available, including standard and child-related ones, as well as limited benefits for retirees.
Sales Tax
Maine's base sales tax rate is 5.5%, and unlike many other states, local jurisdictions cannot impose additional surcharges. The tax applies to most sales of goods, as well as certain services, including rentals, entertainment events, hair salons, and tourism services. Groceries, prescription drugs, and certain medical items are exempt. Determining the taxable base and the correct sales tax rate can be quite complex and requires a professional approach and knowledge of state law. Our firm provides services for obtaining a Sales Tax Certificate and for preparing and filing the Sales and Use Tax Return. We advise business owners on all matters related to this tax, including registration, calculation, and reporting.
Property Tax
Property tax in Maine is set at the municipal level. The statewide average effective rate is about 1.09% of market value, but can vary significantly depending on location. For example, in tourist areas (on the coast) rates can be higher, especially on second homes or commercial real estate. The state offers benefit programs including the Homestead Exemption, a property tax credit for seniors, and exemptions for veterans and people with disabilities. Property is assessed annually, and owners can appeal.
Business Taxes
Maine imposes a Corporate Income Tax on a progressive scale from 3.5% to 8.93%, depending on the company's profit level. This is one of the higher top rates among U.S. states. The tax applies only to C-corporations. All companies doing business in Maine are required to file an Annual Report (due by June 1 each year). Our firm provides services for business registration, Annual Report preparation, corporate tax calculation, support for LLCs and S-corporations, and tax planning consulting to minimize overall tax burden.
Excise Taxes
Maine levies excise taxes on gasoline, tobacco, alcohol, car rentals, tourism services, ferry transportation, and legal cannabis sales. Excise rates vary by product category and require separate registration and reporting. To work with excise-taxable goods, companies must obtain state licenses and comply with specific storage and labeling requirements.
Favorable Tax Conditions
Despite the high income tax rates, Maine offers a number of competitive advantages for small business and startups, including tax credits for investment and job creation, and programs supporting eco-friendly business, agriculture, and high technology. The absence of local surcharges on sales tax simplifies tax administration. Equipment tax incentives (BETR and BETE) are also available, allowing companies to receive a refund of part of the property taxes paid on equipment used in manufacturing. This is especially important for manufacturing, construction, and technical companies.
Compared to Other States
Maine is among the states with a high income tax burden and one of the highest corporate tax rates. However, unlike New York, Illinois, or California, Maine has no city-level income taxes and no additional local surcharges on sales tax, which makes the system more predictable. In addition, the sales tax rate is lower than in most other Northeastern states. Maine also requires businesses to file annual reports on tangible personal property, including furniture, equipment, tools, and vehicles — similar to Pennsylvania and Maryland. That said, the BETE program allows new equipment to be exempt from taxation under certain conditions.
