The Illinois Department of Revenue (IDOR) will begin accepting 2017 individual state returns on Jan. 29, the same day that the federal Internal Revenue Service (IRS) will begin accepting federal individual income tax returns.
IDOR reminds taxpayers that filing returns electronically and utilizing direct deposit is the fastest way to receive refunds. The agency estimates that direct deposit refunds will be issued four weeks from the time that error-free returns are submitted. Taxpayers can use the MyTax Illinois online service to file returns, make payments, and check the status of refunds, as well as to look up their IL-PIN, estimated tax payments, and 1099-G amounts. More information is available on the IDOR website at tax.illinois.gov.
