Gambling Losses Up to the Amount of
Gambling Winnings
You must report the full amount of your gambling winnings
for the year on your Schedule 1 (Form 1040). You deduct
your gambling losses for the year on your Schedule A
(Form 1040). Gambling losses include the actual cost of

wagers plus expenses incurred in connection with the
conduct of the gambling activity, such as travel to and
from a casino. You can't deduct gambling losses that are
more than your winnings. Generally, nonresident aliens
can't deduct gambling losses on your Schedule A.

Diary of winnings and losses. You must keep
an accurate diary or similar record of your losses
and winnings.

Your diary should contain at least the following information.
• The date and type of your specific wager or wagering
activity.
• The name and address or location of the gambling establishment.
• The names of other persons present with you at the
gambling establishment.
• The amount(s) you won or lost.

Proof of winnings and losses. In addition to your diary,
you should also have other documentation. You can generally
prove your winnings and losses through Form
W-2G, Certain Gambling Winnings; Form 5754, Statement
by Person(s) Receiving Gambling Winnings; wagering
tickets; canceled checks; substitute checks; credit records;
bank withdrawals; and statements of actual
winnings or payment slips provided to you by the gambling
establishment.
