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 $10,000 pension exemption for retirees, and provides a generous Social Security deduction that fully shields lower-income residents from state tax on their benefits.

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 Three-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 three base MFJ brackets are 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 roughly $1.05M, 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 − $20,600 ($15,300 standard deduction + $5,300 personal exemption) = $79,400 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% × ($79,400 − $64,850) = 7.15% × $14,550 = $1,040
• Total Maine income tax: $5,157
• Effective rate: 5.16%

This $5,157 state income tax bill sits on top of federal income tax obligations. Maine does not allow a deduction for federal taxes paid on the state return (unlike some states such as Iowa and Oregon).

Maine Standard Deduction: Federal Conformity 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: $15,300
• Married Filing Jointly: $30,600

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 $10,000 federal SALT cap), 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

Unlike the federal government — which suspended the personal exemption from 2018 through 2025 under the Tax Cuts and Jobs Act — Maine reinstated its own state-level personal exemption. 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 higher-income filers.

Social Security Exemption: Income-Based Relief for Maine Retirees

Maine has expanded its Social Security income exemption in recent years to provide meaningful relief for lower and moderate-income retirees. The exemption structure is income-based rather than a flat universal exemption:

• Lower-income threshold: Residents with income below certain thresholds can fully exempt their Social Security benefits from Maine taxable income.
• Phase-out range: The exemption phases out as income rises above the threshold — a portion of Social Security becomes taxable at higher income levels.
• Higher incomes: Residents with income above the upper threshold face partial taxation of Social Security, similar to the federal model where up to 85% of Social Security is taxable at the federal level.

Maine's approach means that a retiree with modest income — primarily Social Security plus a small pension — may pay little or no Maine income tax on their Social Security. This is a meaningful benefit for lower-income retirees who might otherwise face unexpected state tax bills on their primary income source.

Practical Planning Note

Because Maine's Social Security exemption is income-based, managing taxable income near the phase-out threshold can be valuable. 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 Social Security deduction over time.

$10,000 Pension Exemption: What Maine Retirees Need to Know

Maine provides a $10,000 per-person exemption for pension and retirement income. This applies to qualifying pension distributions, including:

• Defined benefit pensions from private employers
• Maine Public Employees Retirement System (MainePERS) distributions
• Military retirement pay — also receives the $10,000 exemption
• Other qualifying retirement income

For a married couple who both receive pension income, the exemption can shelter up to $20,000 of combined pension income from Maine taxation — saving up to $1,430 in Maine income tax at the 7.15% top rate.

Pension Exemption vs. Full Retirement Exemption States

Maine's $10,000 pension exemption is meaningful but not as generous as states offering full retirement income exemptions (such as Iowa, which fully exempts all retirement income for residents 55+). For a retiree drawing $50,000 annually from a pension, only the first $10,000 is sheltered — the remaining $40,000 is taxable at Maine's ordinary income brackets. This is an important consideration when comparing Maine to neighbor states for retirement planning.

IRA and 401(k) Distributions

IRA and 401(k) distributions are generally taxed as ordinary income in Maine and do not benefit from the $10,000 pension exemption (which is directed at defined benefit pension income and similar distributions). This distinction matters for retirees with substantial IRAs: those distributions face full bracket taxation 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
• Most clothing and footwear: Exempt (Maine is one of a small group of states exempting most apparel)
• 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 assessed value for primary residences — saving homeowners approximately $275–$430/year depending on the local mill rate
• Property Tax Fairness Credit: A refundable credit for lower and moderate-income homeowners and renters where property taxes (or 25% of rent as a proxy) exceed a threshold percentage of income — up to $1,500 for most filers
• 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: Exempt (fully, for lower-income retirees; partially for higher incomes). Maine's expanded Social Security deduction has made the state significantly more retirement-friendly in recent years.
• Pension income: $10,000 per person exempt; income above that threshold taxed at Maine's bracket rates starting at 5.8%
• IRA / 401(k) distributions: Fully taxable as ordinary income at Maine brackets (no pension exemption applies)
• Military retirement: $10,000 exemption — same as civilian pension exemption

A Typical Maine Retiree Scenario

Consider a married couple receiving $28,000 in Social Security (potentially fully or largely exempt), $20,000 in pension income (mostly sheltered by the $20,000 combined exemption), and $30,000 in IRA distributions (fully taxable). Their Maine taxable income after the 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.

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.
