How may I file Form IL-1040?

File your individual income tax return electronically by using

  • MyTax Illinois, available on our website for free,
  • a tax professional, or
  • tax preparation software.

Almost all taxpayers can file electronically.  If you do not wish to file electronically, you may use the paper Form IL-1040.
