Gambling tax in Connecticut
Connecticut combines a high top rate with no gambling loss deduction, which is an unusually expensive pairing. The ladder runs from 2% to 6.99%, and none of it can be offset by the losses that produced the winnings.
Connecticut at a glance
Connecticut does not allow gambling loss deductions.
High rate, no offset
Most states refusing the loss deduction are cheap: Ohio charges 2.75%, Indiana 2.95% at the state level, Illinois 4.95%. Connecticut refuses it at rates reaching 6.99%. For a bettor whose winning and losing columns are both large, that costs more than a higher-rate state that accepts losses. New York's top rate is well above Connecticut's, but New York lets an itemizing bettor deduct, so on a break-even season the Connecticut bill can comfortably exceed the New York one. Joint filers do get roughly double-width brackets here, which is one of the few state-level levers available.
Connecticut gambling tax FAQ
Are gambling losses deductible in Connecticut?
No. Connecticut taxes gross winnings, so a break-even season still produces a full state bill.
Does filing jointly help in Connecticut?
Yes, more than in most states. The joint brackets are roughly twice as wide as the single ones, which keeps more of the winnings out of the higher bands.
