Does Maine Have an Inheritance Tax? Estate Tax Rules for 2026

Maine does not have an inheritance tax. Beneficiaries who receive assets from a Maine estate — whether as heirs under a will, through intestate succession, or via non-probate transfers — do not owe Maine state tax on what they inherit.

But Maine does have a state estate tax, and it comes with a procedural trap that applies to virtually every estate, not just large ones.

Maine Estate Tax: The $7,160,000 Exclusion

Maine is one of a small number of states that imposes its own estate tax separate from federal estate tax. For deaths occurring in 2026, the Maine estate tax exclusion is $7,160,000.

That means: if the total federal gross estate — plus taxable gifts made within one year of death, plus certain Maine elective property — exceeds $7,160,000, the personal representative must file Form 706ME (Maine Estate Tax Return) with Maine Revenue Services. Tax is owed on the amount above the exclusion, at rates starting at 8% and climbing to 12% for estates above approximately $13.16 million.

The exclusion has been increasing steadily:

Form 706ME and any tax owed must be submitted electronically through the Maine Tax Portal within nine months of the date of death.

The Federal Exemption in 2026

The federal estate tax exemption for 2026 is significantly higher. Under the One Big Beautiful Bill Act signed in 2025, the federal exemption was made permanent at elevated levels. Most Maine families will owe no federal estate tax. Maine's $7.16 million threshold is much lower than the federal figure, making the Maine estate tax the more relevant concern for high-asset families in the state.

The Automatic Estate Tax Lien: Applies to Everyone

Here is where things get consequential for every Maine estate, regardless of size.

Maine law places an automatic, statutory lien on all real property and tangible personal property located in Maine at the exact moment the owner dies. This is not triggered by the estate's value. A house worth $300,000 has this lien. A summer camp worth $80,000 has this lien. A property held by someone whose total estate is worth $400,000 — millions below the $7.16M threshold — has this lien.

The lien does not disappear on its own, and title companies will not issue title insurance on a Maine property until it is formally discharged.

How to discharge the lien:

If the estate is below the tax threshold and no Form 706ME is required, the personal representative must file Form 700-SOV (Statement of Value) electronically with Maine Revenue Services. This form documents the estate's value and requests a Certificate of Discharge of Estate Tax Lien.

Once Maine Revenue Services processes the filing and issues the certificate, the personal representative must physically record that certificate at the county Registry of Deeds where the property is located. Effective January 1, 2026, the Registry of Deeds recording fee is a flat $40 per document for non-municipal submitters — a change from the old per-page fee structure that applied previously.

This process must be completed before closing any sale of Maine real estate that passed through the estate. Missing it does not mean the estate owes tax — it means the title is unmarketable until the discharge is recorded.

What If There Is No Real Estate?

If the estate has no real property — only bank accounts, personal property, and financial assets — the automatic lien has no practical impact. The lien applies to real and tangible personal property, but for most families, the real estate question is where it matters.

If the decedent owned only personal property below the $52,500 small estate threshold, they may qualify for the small estate affidavit process and bypass probate and the lien issue entirely. See the Maine small estate affidavit guide for details.

MaineCare Recovery: A Separate Issue From Estate Tax

Families sometimes conflate estate tax with MaineCare (Medicaid) estate recovery. These are different programs with different rules.

Maine's estate tax applies based on total asset value relative to the $7.16M exclusion. MaineCare estate recovery is a separate process where the Department of Health and Human Services seeks reimbursement from the probate estate for long-term care services provided to individuals aged 55 and older. It has nothing to do with estate size — a family with a $200,000 estate can face MaineCare recovery claims if the decedent received nursing home care or home-based long-term care funded by MaineCare.

Summary: What Maine Families Actually Owe

For the overwhelming majority of Maine estates:

• No inheritance tax. Beneficiaries owe nothing.
• No Maine estate tax. Estates under $7,160,000 (2026) pay no Maine estate tax.
• No Form 706ME required. Below-threshold estates do not need to file the Maine estate tax return.
• Form 700-SOV is almost always required. If there is any real estate in the estate, the personal representative must file this form and record the lien discharge certificate before selling or transferring the property.

That last item is the one families consistently miss. It is not a tax. It does not cost money beyond the $40 recording fee. But it takes time to process, and skipping it blocks the real estate closing.

The Maine Estate Settlement Guide includes step-by-step instructions for filing Form 700-SOV, what to submit to Maine Revenue Services, and how to record the Certificate of Discharge at the county Registry of Deeds — including the 2026 flat-fee recording schedule.
