Massachusetts Powerball Tax Calculator: How Much Would You Keep?
Estimate a Massachusetts Powerball cash payout after federal and Massachusetts income taxes. See the 24% federal withholding and 5% state withholding separately from the additional 4% surtax that can apply to high income.
Massachusetts Withholds 5%, but a Giant Powerball Win Can Face a 4% Surtax Too
Massachusetts generally taxes ordinary personal income at 5%. Beginning above the annual surtax threshold, another 4% applies. For tax year 2026, that threshold is $1,107,750 — far below a typical Powerball cash payout.
State withholding
Mass Lottery withholds 5% Massachusetts tax from qualifying prizes, but that does not automatically cover the millionaire surtax.
Millionaire surtax
For 2026, taxable income above $1,107,750 is subject to an additional 4% Massachusetts surtax.
Powerball-sized income
Above the surtax threshold, the Massachusetts marginal rate on ordinary taxable income is effectively 9% before considering individual deductions or credits.
This is why a simple “5% Massachusetts tax” calculator would be misleading for a jackpot. The 5% Lottery withholding is shown separately from the estimated final Massachusetts tax.

The winning-ticket state is fixed to Massachusetts. Use the current stored Powerball jackpot and cash option or enter your own amounts. For a Massachusetts resident, the state estimate applies the 5% ordinary rate plus the 2026 surtax to income above the threshold.
Massachusetts Powerball payout estimate
Estimated share of the cash option remaining after modeled federal and Massachusetts tax.
Massachusetts estimate is deliberately simplified: other income is treated as Massachusetts taxable income before the prize, and state exemptions, deductions, credits and special income categories are not modeled.
Massachusetts Lottery Withholding on a Powerball Jackpot
Mass Lottery currently states that prizes greater than $5,000 have 24% withheld for federal tax and 5% withheld for Massachusetts tax.
| Tax layer | Withholding | Threshold | What it means |
|---|---|---|---|
| Federal | 24% | Prize greater than $5,000 | Initial withholding only; final federal liability is estimated separately. |
| Massachusetts | 5% | Qualifying Lottery prizes | Does not automatically include the full 4% millionaire surtax exposure. |
A Powerball winner can owe more Massachusetts tax than the 5% withheld. The calculator therefore shows a separate Massachusetts reserve estimate.
Massachusetts 4% Surtax Threshold for 2026: $1,107,750
Massachusetts imposes an additional 4% tax on taxable income above an inflation-adjusted threshold. For tax year 2026, the threshold is $1,107,750.
Ordinary Massachusetts rate on the taxable income modeled here.
The additional surtax applies to taxable income above the threshold.
At Powerball-sized ordinary income, much of the prize sits above the 2026 surtax threshold.
The surtax is not 4% of the entire jackpot. It applies to taxable income above the 2026 threshold. The calculator measures the surtax attributable to the prize by comparing the modeled surtax with and without the prize.
Massachusetts Taxes Lottery Winnings as Income
Massachusetts includes lottery and gambling winnings in Massachusetts gross income. For Massachusetts purposes, the cost of the winning ticket can reduce taxable lottery income, although that tiny adjustment is not material to a Powerball-sized estimate and is not modeled here.

Massachusetts Powerball Tax FAQs
Does Massachusetts tax Powerball winnings?
Yes. Massachusetts treats lottery winnings as taxable income. A Massachusetts-bought Powerball prize can therefore face both federal and Massachusetts income tax.
How much Massachusetts tax is withheld from a Powerball jackpot?
Mass Lottery states that 5% is withheld for Massachusetts tax on qualifying prizes, while 24% federal tax is withheld on prizes greater than $5,000.
Is the 5% Massachusetts withholding the final state tax?
Not necessarily. Massachusetts also imposes a 4% surtax on taxable income above the annual surtax threshold. For 2026, that threshold is $1,107,750.
What is the Massachusetts millionaire tax threshold in 2026?
The Massachusetts Department of Revenue sets the tax-year 2026 surtax threshold at $1,107,750 of taxable income.
Does that mean Massachusetts taxes the whole jackpot at 9%?
No. The ordinary rate is 5%, and the additional 4% surtax applies only to taxable income above the 2026 threshold. For a very large jackpot, however, most of the taxable prize can sit above that threshold.
Does Massachusetts tax nonresident Powerball winners?
Yes, when the winnings are Massachusetts-source income. Massachusetts specifically includes a multi-jurisdictional lottery when the ticket was bought within Massachusetts.
Can I deduct the cost of my winning Powerball ticket in Massachusetts?
Massachusetts allows the cost of the winning ticket or chance to reduce taxable lottery winnings. This calculator does not model that small adjustment because it is immaterial compared with a Powerball jackpot.
Why does filing status matter if Massachusetts has a flat 5% rate?
The federal calculation still depends heavily on filing status. The simplified Massachusetts state model on this page uses taxable income directly and does not attempt to reproduce every Massachusetts exemption or deduction.
Does the 4% surtax threshold change every year?
The threshold is adjusted annually for inflation. That is why this page displays a visible last-checked date and uses the 2026 threshold rather than the original $1 million figure.
Is this Massachusetts Powerball tax calculator exact?
No. It is an educational planning estimate. It does not reproduce every Massachusetts exemption, deduction, credit, special income category, part-year residency rule, trust or entity issue. A real jackpot winner should obtain professional federal and Massachusetts tax advice.
