In 2011 as the state legislature finalized its lame-duck session and the clock ticked toward midnight, then-Rep. Annazette Collins of Chicago’s West Side joined a majority of her fellow Democrats and supported a 67% income tax increase. Corporate income taxes went up 46%.

On Wednesday, Collins became the latest public official charged in a federal corruption probe alleging she didn’t pay her own taxes. It’s a tool prosecutors often use to encourage cooperation on more significant matters; the winding corruption probe underway at U.S. Attorney John Lausch’s office is no exception.

The irony, of course, is that several of the public officials embroiled in federal tax indictments so far — allegedly trying to evade their own tax burden — were consistent, reliable votes to raise taxes on everyone else. Taxes for thee but not for me?

Collins, who lobbied for Commonwealth Edison and ran her own consulting firm, is slated to be arraigned Tuesday and expected to plead not guilty. She is charged with two counts of “willfully filing a false individual income tax return, two counts of willfully failing to file a corporate income tax return, and one count of willfully failing to file an individual income tax return,” according to the indictment.

For calendar year 2014, about a year after she left the General Assembly, she claimed personal income of $11,533. For the next year, she claimed $10,154, the feds allege. She didn’t file with the IRS for two years on her lobbying and consulting firm, according to the feds. She joins several other public officials connected to the ComEd corruption case who face tax-related charges.Former Rep. Eddie Acevedo, Democrat of Chicago, was charged along with two of his sons in tax evasion cases. Prosecutors accuse Acevedo of underreporting his income, failing to pay what he owed and failing to file timely returns. His sons Alex and Michael are accused of underestimating income and/or failing to file and pay taxes in certain years. They all pleaded not guilty.
