What to know
Connecticut takes back the benefit of its lower brackets at high incomes; for large wins the tax is higher than the brackets alone show.
Connecticut taxes its residents on winnings from anywhere. If you won in another state as a non-resident, that state may tax the prize too, and your home state usually gives a credit for it. The federal tax is the same everywhere: see the 2026 federal rules, or compare every state.
