Connecticut Powerball Tax Calculator: How Much Would You Keep?
Estimate a Connecticut Powerball cash payout after federal and State taxes. Connecticut Lottery currently withholds the full 6.99% top State rate from reportable CT Lottery winnings, including Powerball.
Connecticut Already Withholds the Full 6.99% Top State Rate
Connecticut differs from states where Lottery withholding is well below the final marginal rate. CT Lottery currently withholds 6.99%, which is also Connecticut's top individual income-tax rate. The final calculation still matters because Connecticut uses progressive brackets, exemption phaseouts, a 2% rate add-back, tax recapture and a personal tax credit.
State withholding
Reportable Connecticut Lottery winnings are subject to 6.99% State withholding, whether the winner is a Connecticut resident or not.
Progressive tax schedule
The underlying Connecticut schedule runs from 2% through 6.99%, so the final State tax is not literally a flat 6.99% of every dollar.
Jackpot-scale result
At giant-jackpot income, the lower brackets and Connecticut's recapture system make the final State liability land extremely close to the 6.99% amount already withheld.
Connecticut did not move to a 7.99% top rate in 2026. A bill proposed that increase, but the current 2026 CT Lottery and DRS materials still use 6.99%.

Connecticut Powerball Withholding Rates
CT Lottery currently states that federal income tax is withheld at 24% on gambling winnings valued at more than $5,000. Connecticut State income tax is withheld at 6.99% on reportable Connecticut Lottery winnings and applies regardless of the winner's state of residence.
| Tax layer | Withholding | What it means |
|---|---|---|
| Federal | 24% | Advance payment only. Final federal tax is progressive and can be substantially higher on a jackpot. |
| Connecticut | 6.99% | Advance State payment. On giant prizes it is usually very close to the modeled final Connecticut liability. |
Do not subtract 6.99% twice. The Connecticut withholding is a payment toward the final State liability. The calculator compares it with the modeled final tax and shows the difference separately.
The Final Connecticut Tax Is More Than a Simple 6.99% Multiplication
Connecticut's current calculation starts with Connecticut adjusted gross income, subtracts a filing-status personal exemption, applies the progressive tax schedule, then adds the 2% tax-rate phase-out amount and tax recapture before applying any available personal tax credit.
What the State engine includes
- Connecticut personal-exemption phaseout by filing status.
- 2%, 4.5%, 5.5%, 6%, 6.5%, 6.9% and 6.99% tax bands.
- 2% tax-rate phase-out add-back.
- Connecticut tax recapture.
- Personal tax credit phaseout.
- Incremental tax attributable to the Powerball prize for residents.
Connecticut Uses a Tax Recapture at Higher Income
Connecticut's tax calculation includes extra recapture amounts as adjusted gross income rises. At very high income, the current maximum recapture is $3,400 for Single/MFS, $5,320 for Head of Household and $6,800 for MFJ.
Single / MFS maximum
The current high-income recapture table tops out at $3,400 for Single and Married Filing Separately.
Head of Household
The maximum high-income tax recapture for Head of Household is $5,320.
Married Filing Jointly
The current MFJ high-income recapture reaches a maximum of $6,800.
For a nine-figure jackpot, withholding can end up almost perfectly matched. The lower tax bands reduce the average rate below 6.99%, while Connecticut's phase-out add-back and recapture narrow much of that gap.
What If You Buy the Winning Powerball Ticket in Connecticut but Live Elsewhere?
Connecticut DRS says reportable Connecticut Lottery winnings — including Powerball bought from a Connecticut Lottery agent — are Connecticut-source income for a nonresident. Nonresident tax is calculated in the same manner as a resident and then prorated using the Connecticut-source share of Connecticut adjusted gross income.
The calculator compares Connecticut tax with the prize against Connecticut tax on the entered other income alone.
The Connecticut Powerball prize is treated as Connecticut-source and entered other income as non-Connecticut-source. Home-state tax or credits remain separate.
The 6.99% withholding still applies to the CT Lottery payment regardless of residence. The final nonresident return may produce a different Connecticut liability, and the winner's home state can create another tax or credit calculation.
Connecticut Lottery No Longer Publishes Winners' Names Without Consent
Beginning October 1, 2025, CT Lottery says it no longer publishes winners' names without written consent under Public Act 25-112. Current winner listings commonly show “Winner” rather than the claimant's name.
Rule changed
The new publication policy took effect October 1, 2025.
Name publication is optional
CT Lottery says it will not publish a winner's name without written consent.
Visible on winner lists
Current 2026 winner lists often display the claimant simply as “Winner,” including Powerball prize claims.
