What a prize is worth in Connecticut

Three prizes, as the cheque is written and after the federal return. The return is a single filer earning $50,000 besides the prize, with the 2026 brackets and standard deduction; other income changes the bill, which is what the calculator is for. What you finally owe Connecticut is worked out on its own return at its own income-tax rates, so the state line here is the withholding.

A $1,000 prize has nothing withheld federally and is under the $2,000 at which the lottery reports it on Form W-2G, but it is still taxable income. Connecticut starts withholding on prizes of $2,000 or more. The withholding is a deposit against the federal bill, not the bill: on $1,000,000 the 24% falls $94,680 short, and on $1,000, with nothing withheld, about $120 is still owed.
