Superbowl Sunday is perhaps the biggest one day celebration in all of America.  It’s that one day when everyone, from your office secretary to your betting buddies at the local pub, put down some bucks in Superbowl office pools or place bets legally and illegally.  Some are estimating that more than $10 billion will be bet this year on Superbowl Sunday on office pools, football final scores and even what team wins the coin flip. 

Regardless of the gambling venue, bettors are required to report winnings on income-tax returns. How seriously people take this responsibility is anyone’s guess.

It seems that most people don’t really know that they are supposed to report it on their federal income tax return.  According to one H&R Block survey, only one-third of those responding realized gambling winnings are taxable.

If you receive money, prizes or awards like a trip or new car from a lottery, a local raffle, a casino or sports betting, you are supposed to report the winnings as income on Schedule A of your federal-tax return. You could be subject to estimated tax payments on your winnings as well.

If you win an office pool, you technically are supposed to report it.

But the IRS is more concerned about Internet betting, which is easier to track through credit cards. And the most likely time a gambling situation could come to the IRS’ attention is during an audit.

Gambling losses are deductible, but only to the extent you use them to reduce winnings. In other words, you can’t deduct net losses. And if you are deducting losses, the IRS requires an accurate log of your betting.

“The larger gamblers do keep track,” said Taylor, adding that a lot of casinos furnish tracking cards on request.
