Quick Answer
In Massachusetts, inherited IRAs carry real tax obligations. Distributions count as ordinary income, taxed at a flat 5% under Part B, with a 4% surtax kicking in above $1.08 million. Non-spouse beneficiaries must empty the account within 10 years per the SECURE Act. Pull too much in a single high-income year and you risk crossing that surtax threshold unexpectedly. Missing your filing deadline costs $500.

Inheriting an IRA in Massachusetts is not a tax-free windfall. Every dollar you pull out is ordinary income, taxed at the state’s flat 5% Part B rate, and once your total income clears $1.08 million, an additional 4% surtax applies on top of that. Massachusetts levies no separate inheritance tax, but it taxes distributions fully regardless of whether the original account was held at Fidelity in Boston or a credit union in Arizona.
Non-spouse beneficiaries face the SECURE Act’s 10-year withdrawal deadline. That clock starts the year the original owner dies. Spreading distributions strategically across those 10 years, rather than draining the account all at once, is usually the smarter tax move.
What Happens When You Inherit an IRA in Massachusetts?
The first thing to understand is simple: you owe Massachusetts income tax on whatever you withdraw. The rate is 5%, flat. Large balances can push your total income past $1.08 million, adding that 4% surtax to everything above the threshold.
Massachusetts has no inheritance tax. That’s the good news. The bad news is the state doesn’t care where the IRA originated; if you’re a Massachusetts resident receiving distributions, the Department of Revenue wants its share.
Non-spouse beneficiaries must withdraw the entire balance within 10 years under the SECURE Act. Say you inherit a $400,000 traditional IRA from a parent who died in 2024. You have until December 31, 2034 to withdraw every cent. Taking roughly $40,000 per year keeps each distribution manageable and avoids clustering taxable income into one ugly year. If you happen to be in a low-income year, taking a larger chunk then, say $70,000 or $80,000, can actually lower your overall tax burden across the decade.
Massachusetts also folds the full value of an inherited IRA into the decedent’s gross estate for estate tax purposes. The 2023 exemption sits at $2 million, so estates below that threshold owe nothing at the state level, though the IRA distributions themselves remain taxable as income to whoever inherits them.
Key Takeaway: Inheriting an IRA in Massachusetts triggers income tax on every distribution, at 5% flat plus a 4% surtax above $1.08 million. Non-spouse beneficiaries must clear the entire balance within 10 years. Spreading withdrawals across that window usually produces a lower total tax bill than taking everything at once.
