If you’re asking about taxes on inheritance in Massachusetts, the short answer is that you personally do not owe a state tax just for receiving money or property from someone who died. Massachusetts has no inheritance tax. It does have an estate tax, but that tax is paid by the estate before anything reaches you. The one place a tax bill can land on you later is income: some inherited assets, especially retirement accounts, produce taxable income when you withdraw or sell them.
No Inheritance Tax in Massachusetts
An inheritance tax would put the bill on you, the heir, based on what you received. Massachusetts got rid of that tax for deaths after December 31, 1975.1Massachusetts Department of Revenue. AP 500: Estate and Inheritance Tax What replaced it is an estate tax, which is calculated on the value of the deceased person’s total property and paid out of the estate’s own assets. By the time your share is distributed, that tax has already been handled.
Practically speaking, this means most beneficiaries in Massachusetts receive their inheritance with no state tax paperwork of their own to file for it. The check, the deed, the account transfer — none of it goes on your Massachusetts income tax return as taxable income.
The Massachusetts Estate Tax and the $2 Million Line
Massachusetts taxes estates worth more than $2 million. Estates at or below that amount get a credit of up to $99,600 that wipes out the tax entirely, a credit created by a 2023 law and applied to deaths on or after January 1, 2023.2Massachusetts Department of Revenue. FAQs: New Estate Tax Changes
The gross estate includes almost everything the deceased owned or held an interest in: real estate, bank and investment accounts, vehicles, personal property, life insurance proceeds (even those paid directly to a named beneficiary), retirement accounts, jointly held property, and assets over which the deceased held a general power of appointment.3Massachusetts Department of Revenue. Massachusetts Estate Tax Guide Debts, funeral costs, administration expenses, property passing to a surviving spouse, and gifts to qualified charities are deductible, and those deductions can pull an estate below the threshold.
The Cliff, With Numbers
Massachusetts calculates the tax on the entire estate once you cross $2 million, not just the portion above it. Rates are graduated, starting at 0.8% and climbing to 16% on amounts above roughly $10 million, applied to the “adjusted taxable estate,” which is the taxable estate minus $60,000.3Massachusetts Department of Revenue. Massachusetts Estate Tax Guide
Take a $2.5 million estate with $80,000 in allowable deductions. The taxable estate is $2,420,000, the adjusted taxable estate is $2,360,000, and the tax under the rate table comes to roughly $130,400. Subtract the $99,600 credit and the estate owes about $30,800. A $2 million estate, by contrast, owes zero. That’s the cliff, and it’s the reason estate planning in Massachusetts pays such close attention to the $2 million line.
Federal Estate Tax Is a Separate Question
A federal estate tax also exists, but the exemption is much higher: $15 million per individual for 2026, set by the One Big Beautiful Bill signed on July 4, 2025.4Internal Revenue Service. What’s New — Estate and Gift Tax The two taxes are calculated independently. A $3 million estate owes Massachusetts estate tax but nothing federally.
One place the two systems diverge in a way families notice: portability. Federal law lets a surviving spouse use the deceased spouse’s unused exemption, effectively doubling what a married couple can pass on tax-free at the federal level.5Internal Revenue Service. Frequently Asked Questions on Estate Taxes Massachusetts does not offer portability. Each spouse’s estate is measured on its own against the $2 million threshold, so a couple with a combined estate above that number can’t simply rely on the survivor to absorb the exemption.
When an Inheritance Does Create a Tax Bill for You
The inheritance itself is not taxable income. Cash, a house, or stocks passing to you from an estate don’t go on your Massachusetts or federal income tax return as income. What happens after you receive them is a different story. Rent from an inherited property, dividends from inherited stocks, and interest from an inherited bank account are all taxable to you in the year you receive them, the same as any other income you earn.
Stepped-Up Basis Cuts Capital Gains When You Sell
When you inherit an asset like real estate or stock, its cost basis resets to the fair market value on the date the original owner died.6Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent If a parent bought a house for $150,000 and it was worth $500,000 at their death, your basis is $500,000. Sell it for $510,000 and you owe capital gains tax only on the $10,000 of appreciation after the death, not on the $360,000 that built up during your parent’s lifetime. Sell at or below $500,000 and there’s no capital gains tax at all.
Income in Respect of a Decedent
One important category of assets does not get a stepped-up basis: income the deceased had earned but not yet received. This is called income in respect of a decedent, and the most common examples are traditional retirement accounts, unpaid wages or bonuses, and accrued but unpaid interest.7eCFR. 26 CFR 1.691(a)-1 – Income in Respect of a Decedent When you receive these, you owe ordinary income tax on them just as the deceased would have.6Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
Inherited Retirement Accounts Are the Big One
Inherited traditional IRAs and 401(k)s are the single biggest source of unexpected tax bills for beneficiaries. Every dollar you withdraw is taxed as ordinary income.8Internal Revenue Service. Retirement Topics – Beneficiary There is no stepped-up basis because the account was funded with pre-tax dollars and the IRS is collecting the deferred tax on the way out.
How fast you have to take the money depends on your relationship to the person who died:
- A surviving spouse can roll the account into their own IRA and take distributions on their own schedule, or treat it as an inherited IRA and stretch withdrawals over their life expectancy.
- Certain other eligible designated beneficiaries — minor children of the deceased, disabled or chronically ill individuals, and anyone less than 10 years younger than the deceased — can also stretch distributions over their own life expectancy.
- Everyone else, which covers most adult children and other heirs, has to empty the account by the end of the tenth year after the year of death. If the original owner had already started required minimum distributions, annual withdrawals during the 10-year window may also be required.9Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
The 10-year rule is a planning problem worth thinking about. Pulling everything in one year can push you into a much higher tax bracket. Spreading withdrawals across all 10 years often keeps more of the money by keeping you in lower brackets. Inherited Roth IRAs follow the same 10-year timeline, but because Roth distributions are generally tax-free, the pressure is much lower.
Ways to Reduce the Massachusetts Estate Tax
Because $2 million is a low threshold compared to the federal exemption, strategies that seem unnecessary elsewhere carry real weight in Massachusetts.
- Lifetime gifting. The federal annual gift tax exclusion lets you give up to $19,000 per recipient in 2026 without using any lifetime exemption or filing a gift tax return, and a married couple can give $38,000 per recipient. Massachusetts has no gift tax, so these transfers shrink the taxable estate without any state-level cost.4Internal Revenue Service. What’s New — Estate and Gift Tax
- Irrevocable life insurance trusts. Life insurance proceeds are in the gross estate if the deceased owned the policy. Transferring the policy to an irrevocable trust removes the proceeds from the taxable estate, but the transfer must happen at least three years before death to be effective.
- Charitable giving. Assets left to qualified charities are fully deductible from the gross estate. For an estate sitting just above $2 million, a charitable bequest can bring the total below the threshold and cancel the tax.
- Credit shelter trusts for married couples. Property passing to a surviving spouse qualifies for an unlimited marital deduction, deferring tax to the second death. But because Massachusetts does not offer portability, the survivor’s estate is measured against its own $2 million line. Trusts that use both spouses’ exemptions remain a common tool in Massachusetts even when they’d be unnecessary at the federal level.
The gap between the state’s $2 million threshold and the federal $15 million exemption is where most Massachusetts planning happens. If your family’s estate falls in that range, the strategies above are the ones worth talking through with an estate planning attorney.
