As a taxpayer, you’re probably used to the IRS getting a share of your income. But unfortunately, the agency’s reach extends to whatever additional income you bring in, including gambling winnings. If you have a good day at the track or casino, you should know that your winnings are indeed taxable at the federal level, and depending on where you live, you might pay state taxes as well. And it doesn’t matter how much you win either — you’re technically required to report all of your gambling winnings and pay taxes accordingly.
