Illinois taxpayers will have to wait until Jan. 30 to file both their federal and state tax returns. The Internal Revenue Services has to comply with the American Taxpayer Relief Act by updating its forms and processing systems before it can accept tax returns.
As a result, Illinois taxpayers will have to begin filing state tax returns later than usual because in Illinois, federal tax forms must be completed before state forms. “We want to make sure that what they’re filling out is an accurate form,” says Susan Hofer, spokeswoman for the Illinois Department of Revenue.
There is not a set date for those with complex returns, but the IRS says they hope to begin accepting tax returns, including these tax forms, between late February and into March.
