Maine Income Tax Guide 2026: 4 Brackets, 9.15% Top Rate & Simple 5.5% Sales Tax

Maine levies income tax across four brackets, with a 7.15% rate applying from $64,850 up to $1,000,000 in taxable income for single filers, and a new 2% millionaire surtax pushing the marginal rate to 9.15% above $1,000,000 (effective January 1, 2026). Maine's overall tax design has meaningful relief features: the state sets its own standard deduction and personal exemption (not simple federal conformity), offers a pension income deduction of up to $49,824 per person for 2026 (reduced by any Social Security benefits received), and fully exempts Social Security benefits from state tax.

For residents and those considering a move to Maine, the state's sales tax picture is unusually simple — a flat 5.5% with no local additions anywhere in the state. You pay the same rate whether you shop in Portland, Bangor, or Augusta, with no need to track city or county surcharges. Maine's income tax brackets are indexed to inflation annually, meaning the thresholds shift year to year to prevent bracket creep. This guide covers the 2026 rates, how to estimate your Maine tax bill, and the key planning considerations for workers, retirees, and families.

Maine Income Tax Brackets 2026: How the Four-Rate Structure Works

Maine uses a four-bracket progressive income tax system for 2026, after adding a 2% millionaire surtax effective January 1, 2026. The brackets apply to Maine taxable income — that is, gross income minus your standard deduction, personal exemption (or itemized deductions, if larger), and any other Maine-specific adjustments.

2026 Maine Income Tax Brackets — Single Filers

2026 Maine Income Tax Brackets — Married Filing Jointly

Maine indexes its brackets to inflation annually. The base MFJ brackets are about double the single brackets, but the new millionaire surtax threshold is not — it kicks in at $1.5 million for joint filers, not $2 million (double the $1 million single threshold).

How Maine's Top Rate Compares to the Region

Maine's new 9.15% top rate (7.15% base plus the 2% millionaire surtax on income above $1 million single / $1.5 million joint, effective January 1, 2026) is now the highest top marginal income tax rate in New England — surpassing Massachusetts (5% base plus a 4% surtax above $1,107,750 for 2026, effectively 9%), Vermont (8.75%), Connecticut (6.99%), and Rhode Island (5.99%). New Hampshire famously has no broad income tax on wages. For income below the surtax threshold, Maine's 7.15% top bracket remains in the middle of the New England pack — above New Hampshire and below Vermont — but for million-dollar-plus earners specifically, Maine now tops the region.

Example Tax Calculation — Single Filer at $100,000

Starting from $100,000 gross income:

• Subtract standard deduction and personal exemption: $100,000 − $21,000 ($15,700 standard deduction + $5,300 personal exemption) = $79,000 Maine taxable income
• First bracket: 5.8% × $27,400 = $1,589
• Second bracket: 6.75% × ($64,850 − $27,400) = 6.75% × $37,450 = $2,528
• Third bracket: 7.15% × ($79,000 − $64,850) = 7.15% × $14,150 = $1,012
• Total Maine income tax: $5,129
• Effective rate: 5.13%

This $5,129 state income tax bill sits on top of federal income tax obligations. This example stays below the $102,250 Maine AGI level at which the standard deduction begins to phase out for single filers. Maine does not allow a deduction for federal taxes paid on the state return (unlike some states such as Alabama and Oregon).

Maine Standard Deduction: Maine's Own Amount and What It Means

Maine sets its own standard deduction amounts — it does not simply mirror the federal figure. For 2026, the standard deduction amounts are:

• Single / Married Filing Separately: $15,700
• Married Filing Jointly: $31,400
• Head of Household: $23,550

Filers age 65 or older add $2,050 (unmarried) or $1,650 per married spouse. The standard deduction phases out for Maine income above $102,250 (single) / $204,550 (MFJ) in 2026.

Maine's standard deduction is set annually by Maine Revenue Services and, in recent years, has tracked close to (but not identically to) the federal standard deduction. Most middle-income Maine residents use the standard deduction; itemizing is uncommon unless mortgage interest, state and local taxes (subject to the federal SALT cap, $40,400 for 2026), or charitable contributions exceed the standard deduction amount.

Itemized Deductions in Maine

Maine allows itemized deductions for filers who itemize on their federal return, with some Maine-specific modifications. Maine follows federal treatment for most itemized deduction categories.

Personal Exemption: Maine Kept Its Own

Maine kept its own state-level personal exemption, which the federal return no longer offers. For 2026, Maine's personal exemption is $5,300 per taxpayer (and spouse, if married filing jointly), claimed in addition to the standard deduction. This exemption phases out for single filers with Maine AGI above $341,000 ($409,150 for married filing jointly).

Social Security Exemption: Fully Exempt for Maine Retirees

Maine does not tax Social Security benefits. Maine starts from federal adjusted gross income and subtracts the Social Security and railroad retirement benefits included in it, so the exemption applies at every income level rather than phasing out:

• All income levels: Social Security benefits that are taxable on the federal return are subtracted from Maine income.
• Federal treatment differs: Up to 85% of Social Security can be taxable at the federal level, but that federally taxed portion is not taxed by Maine.
• Pension interaction: Social Security received does reduce the size of Maine's pension income deduction (see below), so it can still affect the Maine tax of retirees who also have pension income.

This means a retiree living mainly on Social Security may pay little or no Maine income tax, which is a meaningful benefit for retirees on fixed incomes.

Practical Planning Note

Because Social Security is exempt but reduces the pension deduction, the mix of income sources matters. Strategies such as Roth conversions (to reduce future required minimum distributions), timing of other income, and charitable giving should be considered with a Maine tax professional to optimize the overall Maine tax result over time.

$49,824 Pension Deduction: What Maine Retirees Need to Know

Maine provides a pension income deduction of up to $49,824 per person for 2026 (up from $48,216 for 2025). It applies to qualifying pension and retirement income, including:

• Defined benefit pensions from private employers
• Maine Public Employees Retirement System (MainePERS) and other government pension distributions
• IRA and employee-plan distributions taken at age 55 or older

The deduction is reduced dollar for dollar by any Social Security and railroad retirement benefits you receive, and from tax year 2025 it phases out for higher-income filers based on federal AGI. Military retirement pay is treated separately: it is fully deductible and is not reduced by Social Security. For a married couple who both receive pension income, each spouse has their own deduction — up to $99,648 combined before any reduction.

Pension Deduction vs. Full Retirement Exemption States

Maine's pension deduction is substantial but is not a full retirement-income exemption like the one Iowa offers (Iowa fully exempts retirement income for residents 55+). For example, a retiree drawing $50,000 a year from a pension and receiving no Social Security can deduct up to $49,824 of it (subject to the AGI phase-out), while a retiree who also receives $30,000 of Social Security has the deduction reduced to $19,824 ($49,824 − $30,000). Income above the available deduction is taxable at Maine's ordinary brackets. This is an important consideration when comparing Maine to neighbor states for retirement planning.

IRA and 401(k) Distributions

IRA and employee-plan (such as 401(k)) distributions can qualify for the same pension income deduction when taken at age 55 or older; distributions before age 55 that are not part of a series of substantially equal periodic payments do not qualify. Amounts above the available deduction are taxed as ordinary income in Maine starting at 5.8%.

Capital Gains Tax in Maine: Taxed as Ordinary Income

Maine taxes capital gains — both short-term and long-term — as ordinary income. There is no preferential capital gains rate in Maine. Long-term capital gains that benefit from the federal 0%, 15%, or 20% federal rates are still taxed at the full Maine bracket rate (up to 9.15% for gains that push total income above $1 million single / $1.5 million joint, the new millionaire surtax threshold effective January 1, 2026; otherwise up to 7.15%) on the Maine return.

This means a Maine resident selling appreciated stock, real estate, or a business interest faces both federal capital gains tax and Maine income tax at up to 9.15% on the gain. Combined with the 23.8% federal long-term capital gains rate (20% + 3.8% net investment income tax for high earners), the total combined rate for a high-income Maine resident can reach approximately 33% on long-term capital gains large enough to trigger the millionaire surtax (around 31% below that threshold).

Real Estate Capital Gains

The federal primary residence exclusion ($250,000 single / $500,000 MFJ) applies for Maine purposes as well — Maine conforms to this exclusion. Gains within those thresholds are excluded from both federal and Maine income tax. Gains above those thresholds are taxable as ordinary income in Maine at rates up to 9.15% (7.15% below the millionaire surtax threshold).

Maine Sales Tax: A Notably Simple Uniform 5.5% System

Maine's sales tax structure is one of its most distinctive and genuinely taxpayer-friendly features — not because the rate is particularly low, but because of its exceptional simplicity:

• Single statewide rate of 5.5% — no county additions, no city additions, no special district surcharges
• Whether you shop in Portland, Augusta, Bangor, Lewiston, or a small coastal town, the rate is 5.5%
• No need for retailers or consumers to track different rates by zip code or municipality

This contrasts sharply with most US states where local jurisdictions layer their own sales taxes on top of the state base rate. In states like Colorado, the combined state, county, city, and special district rate can exceed 10% in some areas. Maine's uniformity eliminates that complexity entirely.

Key Maine Sales Tax Exemptions

• Groceries (unprepared food): Exempt from Maine sales tax — grocery shopping is not taxed
• Prescription drugs: Exempt
• Clothing and footwear: Taxable at 5.5% — Maine has no general clothing exemption
• Prepared food and restaurant meals: Taxed at 8% (higher rate than the base 5.5%)
• Short-term lodging (hotels, vacation rentals): 9% rate
• Car rentals: 10% rate

The higher rates on prepared food and lodging reflect Maine's significant tourism economy — a deliberate policy to generate revenue from visitors and tourist activity rather than residents' everyday consumption.

Maine vs. Other New England States on Sales Tax

Property Tax in Maine: ~0.98% Average Effective Rate

Maine's average effective property tax rate is approximately 0.98% of market value. This places Maine among the lowest in New England — lower than New Hampshire (1.50%), Vermont (1.51%), Connecticut (1.54%), and even slightly lower than Massachusetts (~1.00%).

Property taxes in Maine are set at the municipal level and vary significantly by town. Urban areas like Portland and Bangor tend to have higher effective rates than rural towns, though assessed values also vary. Maine municipalities use property tax revenue as a primary funding mechanism for public schools and local services.

Maine Property Tax Relief Programs

• Homestead Exemption: Maine provides a $25,000 reduction in the just value of primary residences
• Property Tax Fairness Credit: A refundable credit for lower and moderate-income homeowners and renters where property taxes or rent paid exceed a threshold percentage of income
• Tree Growth Tax Program: Reduced assessment for qualifying forest land — relevant for rural Maine property owners

Annual Property Tax Estimates by Area

Maine vs. New Hampshire: Income Tax Comparison for Border Residents

The Maine–New Hampshire comparison is one of the most commonly searched tax questions in the region. New Hampshire famously has no broad income tax on wages and salaries — residents earn income without state income tax deducted. Maine, directly to the east, levies 5.8–9.15% (the top rate includes a new 2% millionaire surtax above $1M single / $1.5M joint, effective January 1, 2026). For workers near the border (Portsmouth, NH area; Kittery, ME area), the difference is significant.

The Key Trade-offs

New Hampshire's lack of income and sales taxes is offset by property taxes that are among the highest in New England. A $400,000 home in New Hampshire generates approximately $6,000/year in property tax at the average 1.50% rate. The same home in Maine generates approximately $3,920/year at the 0.98% average.

Who Does Better in New Hampshire vs. Maine?

• High-income wage earners with modest property: New Hampshire wins — saving 7.15% on income more than offsets the property tax premium
• Retirees with modest income and significant home equity: Maine can be competitive — Social Security exemption and pension deduction reduce the income tax burden, while lower property taxes reduce fixed costs
• Remote workers buying high-value homes: A closer call depending on income level and home value

Retiring in Maine: Income Tax Considerations

Maine's retirement tax picture is mixed — more favorable than its 7.15% top rate suggests, but not as generous as states with full retirement income exemptions.

What Retirees Pay in Maine

• Social Security: Fully exempt at every income level — Maine subtracts Social Security benefits included in federal AGI.
• Pension income: Deduction of up to $49,824 per person (2026), reduced by Social Security received and phased out at higher federal AGI; income above the available deduction is taxed at Maine's bracket rates starting at 5.8%
• IRA / 401(k) distributions: Can qualify for the same pension deduction when taken at age 55 or older; the rest is taxed as ordinary income at Maine brackets
• Military retirement: Fully deductible, with no Social Security reduction

A Typical Maine Retiree Scenario

Consider a married couple receiving $28,000 in Social Security (fully exempt), $20,000 in pension income, and $30,000 in IRA distributions taken after age 55. Each spouse's pension deduction (up to $49,824) is reduced by the Social Security that spouse receives, so how the benefits are split matters, and the deduction phases out at higher federal AGI. Their Maine taxable income after the pension deduction, standard deduction and exemptions could be considerably lower than their gross income suggests — potentially resulting in a Maine tax bill well below what the 7.15% top rate implies. Use the Maine calculator or a Maine tax professional for your exact numbers.

Maine vs. Florida / New Hampshire for Retirement

High-income retirees with large IRA balances often find Florida (no income tax) or New Hampshire (no income tax) more favorable. However, Maine's lower property taxes relative to New Hampshire, combined with the Social Security exemption and pension deduction, make Maine competitive for retirees with moderate income who value Maine's quality of life, natural environment, and healthcare access.
