CPA Services in Maine
Maine’s economy is centered on tourism, fishing and aquaculture, forestry, manufacturing, and a growing remote-work population attracted by the state’s quality of life. Maine has a progressive income tax with rates up to 7.15%, and property taxes vary significantly across the state’s many small municipalities.
The state’s strong small business culture, seasonal tourism economy, and significant retirement population create a broad range of tax planning needs. Maine CPAs are experienced with seasonal business income smoothing, the unique tax treatment of fishing income, vacation rental taxation, and retirement income planning for those who’ve relocated to Maine from other states.

Maine CPA & Tax FAQ
Q: What are Maine’s income tax rates?
Maine has a graduated income tax with rates from 5.8% to 7.15%. The highest bracket (7.15%) applies to income over $54,450 for single filers and $108,900 for joint filers, meaning most Maine wage earners will pay at or near the top rate. Maine taxes residents on all income and non-residents on Maine-source income.
Q: How does Maine tax seasonal tourism businesses?
Maine’s tourism industry creates unique tax situations for seasonal businesses. Sales tax (5.5% on most goods, 9% on lodging, 8% on prepared food) applies to most tourism-related transactions. Seasonal businesses need to register for sales tax even if they only operate a few months per year, and income averaging can help smooth out the tax impact of seasonal income.
Q: What should Maine fishermen know about state taxes?
Commercial fishing income is treated as self-employment income for Maine tax purposes. Maine fishermen may claim deductions for boat depreciation, fuel, maintenance, and other business expenses. Special accounting rules can apply to fish catch income. A Maine CPA familiar with the industry can provide valuable guidance on the intersection of state and federal fishing income rules.
Q: Does Maine have favorable tax treatment for retirees?
Maine offers a pension income deduction of up to $10,000 for qualifying pension and annuity income for residents who are 65 or older or who are totally disabled. Social Security benefits that are taxable at the federal level are also taxable in Maine, though some deduction may apply. Military retirement pay is fully excluded from Maine income tax.
Q: What are Maine’s sales tax rates and exemptions?
Maine has a 5.5% general sales tax, with a 9% rate on lodging, 8% on prepared food, and a 10% rate on auto rentals. Groceries and most clothing are exempt, as are prescription drugs and most professional services. Maine has a relatively simple sales tax structure, though the varied rates for hospitality businesses require attention.
