Illinois gambling tax revenues fell 13.4% due to pandemic shutdown Robert Channick, Chicago Tribune · October 9, 2020 at 7:33 am When Illinois passed sweeping legislation last year to expand gambling in the state, it was envisioned as a way to generate increased tax revenue. But the COVID-19 pandemic has led to a much different result, with gambling tax revenue down by 13.4% for the first full year under the new law. The state’s gambling tax revenue fell by nearly $200 million to $1.2 billion for fiscal year 2020, which ended June 30. Everything from horse racing to bingo took a hit, according to an annual wagering report by the state. East Peoria’s Par-A-Dice saw the largest percentage decline in annual revenue and in revenue over the last five years of all the state’s casinos, according to the data.
