Connecticut lottery tax calculator
Connecticut taxes lottery winnings as ordinary income under its graduated schedule — the prize is stacked on your other income, so the rate depends on the total.
Lump sum: enter the cash option, not the advertised jackpot. Annuity: enter one year's payment.
The prize is stacked on top of this. It decides which bracket the winnings land in — and whether the 24% withheld was too much or too little.

At the counter
What is withheld in Connecticut
Federal first, everywhere: on proceeds over $5,000 the payer withholds 24% of the whole amount — not the part over the line — and reports it on Form W-2G. That is a prepayment. The tax is settled on your return.
Connecticut may also withhold state tax at the counter on larger prizes. That figure is not on this page yet, so the at-claim line is blank — what you see is the Connecticut tax you will owe on the prize, not what is taken at the window.

Questions
How much tax is taken from lottery winnings in Connecticut?
Two layers. Federal: the payer withholds 24% on proceeds over $5,000, and the prize is then taxed on your return as ordinary income at the 2026 rates — up to 37%. State: Connecticut taxes lottery winnings as ordinary income under its graduated schedule — the prize is stacked on your other income, so the rate depends on the total. Connecticut may also withhold state tax at the counter on larger prizes. That figure is not on this page yet, so the at-claim line is blank — what you see is the Connecticut tax you will owe on the prize, not what is taken at the window.
Does Connecticut tax lottery winnings?
Connecticut taxes lottery winnings as ordinary income under its graduated schedule — the prize is stacked on your other income, so the rate depends on the total.
What will the cheque be on a $100,000 prize in Connecticut?
About $76,000 — the prize less $24,000 federal withholding. The tax actually owed for a single filer earning $60,000 elsewhere is about $28,647, so what you keep is $71,354. Your own figure depends on your other income and filing status.
Is the withholding the same as the tax?
No. Withholding is a prepayment at a flat rate the IRS sets for everyone. The tax is worked out on your return from your total income. If your bracket is above 24% you owe the difference in April; if it is below, the excess comes back as a refund. On a jackpot the gap is large — roughly a third of the federal tax is still owed after the 24% is taken.
