Federal, State, and Local Tax Withholding in Maine in 2026

Federal Income Tax

Maine residents are subject to federal income tax, just like all other U.S. citizens. The federal tax is calculated based on a progressive tax system with varying rates depending on income brackets, meaning that individuals pay higher rates on higher income. For the 2026 tax year, the federal tax brackets are as follows:

• 10%: Applies to taxable income up to $11,925 for single filers and up to $23,850 for married couples filing jointly.
• 12% to 24%: Tax rates increase incrementally based on income, with intermediate rates including 12%, 22%, and 24%, covering different portions of taxable income.
• 37%: The top rate applies to taxable income over $626,350 for single filers and $751,600 for married couples filing jointly.

The progressive nature of these rates means that as income increases, additional earnings are taxed at higher rates. These rates apply nationwide and are adjusted annually to account for inflation. Employers withhold federal income tax from each paycheck based on the employee’s Form W-4.

Maine State Income Tax

Maine imposes its own progressive state income tax across three income brackets. The brackets are adjusted annually for inflation using the Chained Consumer Price Index (C-CPI). For 2026, the inflation adjustment multiplied the lowest bracket dollar amounts by 1.303 and the highest by 1.298. The resulting 2026 tax brackets are:

• 5.8%: Applicable to taxable income up to $27,400 for single filers and up to $54,850 for married couples filing jointly.
• 6.75%: Applies to taxable income between $27,400 and $64,850 for single filers, and between $54,850 and $129,750 for joint filers.
• 7.15%: Levied on income over $64,850 for single filers and over $129,750 for married couples filing jointly.

For 2026, the standard deduction is $15,300 for single filers and $30,600 for married filing jointly. The personal exemption is $5,300 per allowance claimed on Form W-4ME. The standard deduction phases out entirely for single taxpayers with income above $177,250 and for married taxpayers with income above $354,550.

Starting in 2026, Maine also imposes a 2% surcharge on the portion of taxable income exceeding $1,000,000 for single taxpayers and $1,500,000 for married taxpayers filing jointly. This means the effective top rate on income above those thresholds is 9.15% (7.15% + 2%).

Maine also allows certain deductions and credits, such as the Property Tax Fairness Credit and the Earned Income Tax Credit (EITC), which can significantly reduce tax liability for eligible residents. These deductions are designed to make taxes more equitable, especially for low and moderate-income earners.

Local Taxes in Maine

Maine does not impose local income taxes, which simplifies income tax filings for residents. However, local municipalities do levy property taxes and sales taxes, which contribute significantly to the state’s revenue system.

• Property Taxes: Levied at the municipal level. Rates vary considerably between municipalities, with urban and coastal areas often seeing higher rates.
• Sales Taxes: Maine imposes a statewide sales tax rate of 5.5% on most goods and services. No additional local sales taxes apply. Groceries are exempt; prepared food, car rentals, and lodging are subject to higher rates of approximately 8% to 10%.

FICA and State Insurance Taxes in Maine in 2026

FICA Taxes include Social Security and Medicare:

• Social Security is taxed at 6.2% on income up to $184,500 in 2026. This wage base increased from prior years. Once an employee’s wages with a single employer cross $184,500 in the calendar year, Social Security withholding stops.
• Medicare is taxed at 1.45% on all income, with an additional 0.9% surtax on wages over $200,000. Employers must begin withholding the additional 0.9% automatically once an employee’s wages exceed $200,000 with that employer in the calendar year, regardless of the employee’s filing status.

Maine employers and employees both contribute to Unemployment Insurance (UI), which supports residents in case of job loss. Employer UI rates are experience-rated and vary by employer.

Pre-Tax Deductions in Maine in 2026

Pre-tax deductions play a crucial role in reducing your taxable income, thereby lowering your overall tax liability. These deductions are taken from your gross income before any taxes are applied, which ultimately reduces the amount of income subject to taxation. Here is a detailed breakdown of common pre-tax deductions that Maine residents can utilize:

Health Insurance Premiums

Employee contributions toward medical, dental, and vision insurance are generally deducted from wages on a pre-tax basis. This means that amounts contributed for these health insurance plans are not included in taxable income, effectively reducing the employee’s federal, state, and FICA tax liability.

401(k) Contributions

Contributions to 401(k) retirement accounts are pre-tax. For 2026, the contribution limit is $24,500, up from $23,500 in 2025, with an additional $7,500 catch-up contribution allowed for individuals aged 50 to 59 and 64 or older. Individuals aged 60 to 63 may contribute an enhanced catch-up of up to $11,250 under the SECURE 2.0 Act.

• Health Savings Accounts (HSAs) are available to individuals enrolled in high-deductible health plans (HDHPs). For 2026, the HSA contribution limit is $4,400 for self-only coverage and $8,750 for family coverage. Funds roll over year to year.
• Flexible Spending Accounts (FSAs) allow employees to contribute pre-tax dollars for medical and dependent care expenses. The FSA contribution limit for 2026 is $3,300. FSAs generally have stricter rules regarding fund rollover.

Income disparities are evident between rural and urban areas, with Portland and the greater Cumberland County area (median household income of $92,983 per the Census Bureau’s 2019–2023 ACS) and other coastal regions enjoying higher income levels compared to inland and rural parts of the state.

Maine Tax Brackets 2026

Maine uses a progressive income tax structure to ensure that taxpayers contribute based on their income level. This means that higher earners pay a higher tax rate, while lower earners benefit from lower rates. Maine’s three brackets are adjusted annually for inflation using the Chained Consumer Price Index published by the U.S. Bureau of Labor Statistics.

For the 2026 tax year, Maine’s income tax rates are divided into three brackets:

For Single Filers

For Married Couples Filing Jointly

The tax brackets for married couples are essentially doubled to account for two incomes:

For Head of Household Filers

Remember that Maine taxable income is gross income minus the standard deduction and personal exemptions. For a single filer claiming one exemption, that means subtracting $15,300 (standard deduction) and $5,300 (personal exemption) from gross wages before applying the brackets above. For most full-time employees, this brings the first $20,600 of gross wages effectively to zero Maine state tax.

The progressive nature of Maine’s tax system ensures that people contribute according to their capacity to pay, which helps fund public services like education, healthcare, and infrastructure while supporting lower-income earners.
