Thanks for that, however, my original question was in regards to previous years. Actually, the law in general. It is NOW an allowable deduction (credit) in Illinois, however, it was NOT in previous years. “You may not claim a credit for tax paid to another state on gambling winnings earned in the other state while you were a resident of Illinois” taken directly from a letter from the IL Dept of Revenue for tax year 2018 and 2017. They changed it beginning in 2019.
my question was, how did they get away with not allowing it previously because of the rules about double taxation re: comptroller of Maryland v Wynne.
