Maine Estate Tax Guide | Settled Estate

Maine is one of the few states that runs its own estate tax. The state taxes the part of a taxable estate that sits above the Maine exclusion amount, which is $7,160,000 for deaths in 2026 (36 M.R.S. Section 4102), at rates of 8%, 10%, and 12%. The personal representative files Form 706ME within 9 months of death. Maine has no inheritance tax, and the federal estate tax reaches only estates above $15 million.

This guide covers who owes the Maine estate tax, the current rates and exclusion, how the spousal rules work, and where the federal estate tax fits for a larger Maine estate.

Does Maine Have an Estate Tax? Yes

Maine imposes an estate tax on the estate of anyone who dies a Maine resident, and on the Maine-situated property of a nonresident, when the taxable estate tops the Maine exclusion amount. For deaths on or after January 1, 2013, the tax applies even when no federal estate tax is due (36 M.R.S. chapter 577).

The Maine exclusion amount is the dividing line. An estate at or below it owes no Maine estate tax. Only the value above it gets taxed.

Deaths in 2024: exclusion of $6,800,000
Deaths in 2025: exclusion of $7,000,000
Deaths in 2026: exclusion of $7,160,000

The statute sets a base figure of $5,600,000 for deaths in 2018 or later, then adjusts it for inflation each year (36 M.R.S. Section 4102). Maine Revenue Services publishes the amount for each year of death. Because the number moves every January 1, confirm the figure for the exact year your loved one died before you decide whether a return is required.

Maine Estate Tax Rates and Brackets

Maine taxes the estate on a graduated schedule, and the tax applies only to the amount above the exclusion, not to the whole estate (36 M.R.S. Section 4103). Here is how the brackets work for a 2026 death, using the $7,160,000 exclusion.

Maine Taxable Estate (2026 Death)	Maine Estate Tax
$7,160,000 or less	$0
More than $7,160,000 up to $10,160,000	8% of the amount over $7,160,000
More than $10,160,000 up to $13,160,000	$240,000 plus 10% of the amount over $10,160,000
More than $13,160,000	$540,000 plus 12% of the amount over $13,160,000

The two upper breakpoints track the exclusion plus $3 million and the exclusion plus $6 million, so they shift each year with the exclusion. An estate worth $8,160,000 in 2026, made up of a paid-off home, a retirement account, and a life-insurance payout, would owe 8% on the $1,000,000 above the exclusion, which comes to $80,000.

Maine Has No Inheritance Tax

People often mix up two different taxes, so it helps to separate them:

An estate tax falls on the estate itself, based on total value, before anything is distributed. Maine has one.
An inheritance tax falls on the person who receives the property, based on what they get and how they were related to the person who died. Maine does not have one.

Because Maine has no inheritance tax, a child, sibling, or friend who inherits from a Maine estate owes Maine nothing on the inheritance itself. That said, two cross-border traps still catch Maine families:

If you inherit from someone who lived in a state that does levy an inheritance tax, such as Pennsylvania, Kentucky, or New Jersey, that state may tax you even though you live in Maine.
If a Maine resident owned real estate in a state with its own estate tax, that state may tax the property inside its borders. This is a common reason to file a return in more than one state.

Form 706ME: Filing the Maine Estate Tax Return

The personal representative files the Maine estate tax return on Form 706ME with Maine Revenue Services. A return is required when the estate is large enough to cross the Maine filing threshold for the year of death, or when the estate needs to record a Maine QTIP election for a surviving spouse.

Due date. Form 706ME is due 9 months after the date of death, the same clock as the federal return (36 M.R.S. Section 4107). Maine grants an automatic filing extension equal to any federal extension or 6 months, whichever is longer. The extension covers filing, not payment: the tax is still due at 9 months, and interest runs on anything paid late.

What it reports. The return starts from the federal gross estate, applies the Maine adjustments (including any Maine elective property and Maine-situated real and tangible property for a nonresident), subtracts deductions, and figures the tax against the exclusion. Estates that also file a federal Form 706 attach it.

Filing the return correctly matters even when the math looks simple, because the Maine QTIP election and the valuation of real estate and business interests both get made on this return.

The Marital Deduction and Maine Elective Property

Property left outright to a surviving spouse passes free of estate tax under the unlimited marital deduction, at both the federal and Maine levels. The tax on that property is deferred until the second spouse dies.

Where Maine differs from the federal system is what happens to a couple's two exclusions. The federal rules let a surviving spouse carry over a deceased spouse's unused exclusion (portability). Maine does not offer portability of its own exclusion amount. Instead, Maine uses a Maine QTIP election and Maine elective property to shelter property that passes to a spouse in a qualifying trust, then taxes that property in the survivor's estate (36 M.R.S. chapter 577; Maine Revenue Services Rule 603).

The practical takeaway for a couple whose combined assets could top one exclusion: the plan has to be built for Maine on purpose. A married couple who leaves everything outright to each other can waste the first spouse's Maine exclusion. A trust structured for the Maine QTIP election can preserve it. The Maine surviving spouse rights guide covers the elective share and the allowances that sit alongside these tax rules.

Federal Estate Tax: When It Applies

The federal estate tax reaches only estates above the federal exclusion, so most Maine estates never touch it. Still, a larger estate has to plan for both layers.

2026 federal exclusion. For deaths in 2026, the federal exclusion amount is $15 million per person and is indexed for inflation. A married couple can shield up to $30 million by combining that with federal portability. Only the amount above the exclusion is taxed, and the top federal rate is 40%.

Form 706. The federal estate tax return, Form 706, is required when the gross estate plus lifetime taxable gifts tops the exclusion, or when the estate elects federal portability for a surviving spouse. It is due 9 months after death, with an automatic 6-month filing extension available on Form 4768. A married couple should weigh filing Form 706 to claim portability even when no tax is due, because it preserves the first spouse's unused federal exclusion.

Gift tax and the annual exclusion. The federal gift and estate taxes share one lifetime exclusion, so large lifetime gifts draw it down. For 2026, you can give up to $19,000 per recipient per year (a married couple, $38,000) without using any lifetime exclusion or filing a gift tax return. Direct payments to a medical provider or a school for someone else, gifts to a spouse, and gifts to charity fall outside the gift tax entirely.

What Counts Toward the Estate

Both the Maine and federal calculations start from the gross estate, which reaches more than the assets you own outright:

Real estate, bank accounts, brokerage holdings, and cash
Retirement accounts, such as IRAs and 401(k) plans
Life insurance you owned or controlled
Business interests and partnership shares
Your share of jointly owned property
Trust assets you kept the power to control
Some gifts made within three years of death

Debts, funeral costs, administration expenses, charitable gifts, and the marital deduction come off the gross estate to reach the taxable estate. That figure, not the headline value, is what gets measured against the exclusion.

Ways to Reduce a Taxable Maine Estate

A larger Maine estate can lower the tax with planning done during life. A few options families weigh with an estate planning attorney:

Annual gifting. Regular gifts under the annual exclusion move value out of the taxable estate over time without a gift tax return.
Irrevocable life insurance trust. Holding a policy in an irrevocable trust keeps the death benefit out of your estate, instead of adding it to the gross estate the way a policy you own does.
Charitable gifts. A bequest to a qualified charity is deductible from the estate dollar for dollar.
Marital planning with a Maine QTIP. Structuring a trust to capture the Maine QTIP election preserves the first spouse's Maine exclusion.

One point trips people up: a revocable living trust does not cut the Maine estate tax. It avoids probate for funded assets, but those assets still count in your taxable estate because you kept control. The how to avoid probate in Maine guide explains that difference, and a transfer on death deed has the same limit: it skips probate on a home without shrinking the taxable estate.

Income Tax on Inherited Assets in Maine

Maine has no inheritance tax, but inherited assets can still generate Maine income tax after you receive them:

Retirement account withdrawals. Money you pull from an inherited IRA or 401(k) is ordinary income for Maine income tax, the same as it was for the person who died. Most non-spouse beneficiaries have to empty an inherited account within 10 years under the SECURE Act.
Capital gains on a sale. When you sell inherited property for more than its stepped-up basis, the gain is taxable income in Maine. Maine taxes capital gains as ordinary income.

Because the basis resets to the date-of-death value, a fast sale often produces little or no gain. The selling inherited property in Maine guide walks through the sale, the transfer tax, and the paperwork the personal representative signs.

When to Bring in a Professional

Estate tax questions sit where federal law, Maine law, and a family's own finances meet. Talk to a tax advisor or estate planning attorney when:

The estate may top the Maine exclusion, the federal exclusion, or both
The estate owns a business, a farm, or property in more than one state
A married couple wants to preserve both Maine exclusions
You need to file Form 706ME or Form 706
You want to make large lifetime gifts

If you are settling an estate now, the Maine probate guide explains how to open the case and where the estate tax return fits in the timeline.

Frequently Asked Questions

Does Maine have an estate tax?

Yes. Maine taxes the part of a taxable estate that sits above the Maine exclusion amount, which is $7,160,000 for deaths in 2026 under 36 M.R.S. Section 4102. The tax runs at 8%, 10%, and 12% on the amount over the exclusion (36 M.R.S. Section 4103), and the personal representative files Form 706ME with Maine Revenue Services.

Does Maine have an inheritance tax?

No. Maine has no inheritance tax, so a beneficiary owes Maine nothing just for receiving an inheritance. If you inherit from someone who lived in a state that does levy an inheritance tax, such as Pennsylvania, Kentucky, or New Jersey, that state may tax you even though you live in Maine.

How much can pass free of Maine estate tax in 2026?

For deaths in 2026, the first $7,160,000 of a Maine taxable estate passes free of Maine estate tax. The exclusion re-indexes each January 1, so confirm the figure for the actual year of death with Maine Revenue Services before you run the numbers.

When is the Maine estate tax return due?

Form 706ME is due 9 months after the date of death, the same deadline as the federal Form 706 (36 M.R.S. Section 4107). Maine grants an automatic filing extension equal to any federal extension or 6 months, whichever is longer, but the tax itself is still due at 9 months.

Can spouses share the Maine exclusion the way they share the federal one?

No. Maine does not offer portability of its own exclusion amount. Instead of a transfer of unused exclusion, Maine uses a Maine QTIP election and Maine elective property rules to defer tax on property left to a surviving spouse, then taxes that property in the survivor's estate (36 M.R.S. chapter 577; MRS Rule 603).

Does a revocable living trust avoid the Maine estate tax?

No. A revocable living trust keeps funded assets out of probate, but those assets still count in your Maine taxable estate because you kept control during life. Only transfers that remove assets from your estate, such as completed gifts or an irrevocable trust, lower the Maine estate tax.
