Massachusetts Inheritance Tax: What Beneficiaries Actually Owe

You just inherited money or property from someone who died in Massachusetts. The first question most people ask: do I owe a tax on this?

The short answer is no — Massachusetts does not have an inheritance tax. There is no state form to file, no percentage withheld from your check, and no bill from the Department of Revenue addressed to you as the person receiving the assets.

But "no inheritance tax" does not mean the estate settlement is tax-free. Massachusetts does impose an estate tax — and that tax is paid by the estate before anything reaches you. Understanding the difference between these two concepts saves a lot of confusion and prevents families from either panicking unnecessarily or being blindsided by delays they did not anticipate.

The Difference Between Inheritance Tax and Estate Tax

An inheritance tax is levied on the person who receives the assets. The rate often depends on your relationship to the deceased — a spouse might pay nothing, while a distant cousin pays a higher percentage. Six states currently impose some form of inheritance tax: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Massachusetts is not among them.

An estate tax is levied on the total net worth of the deceased person's estate before any distribution occurs. The executor pays this tax out of estate funds. Only after it is paid — along with debts and other creditor claims — do beneficiaries receive their shares. The tax burden falls on the estate, not on you.

So when someone dies in Massachusetts, the estate may owe estate tax to the Commonwealth. The beneficiaries owe nothing on the principal they receive.

Who Owes Massachusetts Estate Tax

The Massachusetts estate tax applies when the gross estate, plus adjusted taxable gifts made during the decedent's lifetime, exceeds $2 million. If the total falls below that threshold, no estate tax return needs to be filed and no state estate tax is owed.

For 2026, the federal estate tax exemption sits at $15 million per individual — the result of the One Big Beautiful Bill Act raising it permanently. That means the vast majority of estates face state estate tax exposure in Massachusetts long before they come anywhere near the federal threshold. A Massachusetts family with a home, retirement accounts, and some savings can easily exceed $2 million while remaining far below the $15 million federal mark.

If the estate does exceed $2 million, the executor files a Massachusetts Estate Tax Return (Form M-706) and pays any calculated tax. The marginal rates start at 7% and climb to 16% for the highest brackets. Only the value above $2 million is effectively taxed — thanks to a $99,600 credit that eliminates the punitive "cliff" that existed before 2023.

The 2023 Reform That Changed Everything

Prior to 2023, Massachusetts had one of the harshest estate tax structures in the country. The threshold was $1 million — and the system operated as a cliff. If an estate was worth exactly $1,000,000, it owed zero tax. But if it was worth $1,000,001, the entire estate, back to the very first dollar, was subject to taxation. Middle-class families whose primary wealth was tied up in appreciated Boston-area real estate were frequently forced to sell inherited homes just to generate the cash to pay the Department of Revenue.

In October 2023, the legislature enacted St. 2023, c. 50, retroactive to January 1, 2023. That law did two things: it raised the filing threshold to $2 million, and it introduced a uniform $99,600 credit against any calculated estate tax. The credit effectively kills the cliff. Under the current rules, only the value exceeding $2 million is meaningfully taxed.

A September 2024 amendment went further. Under St. 2024, c. 206, the value of real estate and tangible personal property located outside of Massachusetts is now excluded from the Massachusetts estate tax calculation — retroactive to deaths on or after January 1, 2023. Before this change, the DOR required Massachusetts residents to include out-of-state property in the taxable estate, which was ultimately ruled unconstitutional in Dassori v. Commissioner of Revenue. The legislature codified that ruling.

For beneficiaries: if the estate was open before 2024 and an executor overpaid state estate tax by including out-of-state property, an amended return may be warranted.

What Beneficiaries Do Owe

Just because you receive an inheritance tax-free does not mean inherited assets are forever beyond the reach of taxation. There are two situations where you, as a beneficiary, will have tax obligations:

Income generated after the date of death. If estate assets produce income during the probate period — rent from an inherited property, interest in an estate bank account, dividends from an investment portfolio — that income is taxable. The executor files a Massachusetts Fiduciary Income Tax Return (Form 2) to report it. You will receive a Schedule 2K-1 showing your share of that income, which you report on your personal return.

Selling inherited assets. When you sell an inherited home or investment, you may owe capital gains tax — but the calculation starts from the stepped-up basis, not the original purchase price. Your tax basis in an inherited asset is its fair market value on the date of the decedent's death, not the price paid decades ago. If you sell shortly after inheriting and values have not changed, you may owe little or nothing in capital gains. If you wait years and the property appreciates significantly, your gains will be measured from that stepped-up value.

One critical caveat: beneficiaries cannot finalize a sale of Massachusetts real estate until the estate tax lien is cleared. Massachusetts law imposes an automatic ten-year lien on all real estate owned by the decedent at the time of death. Even if the estate owes zero estate tax, the executor must record either an Affidavit of No Estate Tax at the Registry of Deeds or obtain a Certificate Releasing Massachusetts Estate Tax Lien (Form M-4422) from the DOR before a title insurer will underwrite the transaction. This step is what stalls closings — not inheritance tax, but the lien release process.

Inherited Retirement Accounts Are Different

Retirement accounts — traditional IRAs, 401(k)s, 403(b)s — do not receive a step-up in basis when inherited. These assets are classified as Income in Respect of a Decedent (IRD). Every dollar you withdraw from an inherited traditional retirement account is taxed as ordinary income at your marginal federal and state rates. Liquidating a large inherited IRA in a single year can push a Massachusetts beneficiary into the highest tax bracket, creating a massive tax bill that catches families completely off guard.

The strategy matters here. Depending on your relationship to the decedent and the size of the account, you may have options — a spousal rollover, a ten-year drawdown for non-spouse beneficiaries, or a qualified disclaimer — but each has its own deadline and eligibility requirements.

The Bottom Line for Massachusetts Beneficiaries

If someone left you money or assets in Massachusetts, you do not owe an inheritance tax. What may delay your receipt of those assets is the estate tax process — if the estate exceeds $2 million, the executor must file Form M-706, pay any tax owed, and obtain lien releases before real estate can transfer. Below $2 million, the process is administratively simpler but the lien release step still applies to real property.

Once you actually receive the assets, your tax obligations depend on what you do with them: hold income-producing property, sell appreciated assets, or draw from retirement accounts. The principal inheritance itself arrives tax-free.
