IL-PINs are only assigned to taxpayers who have previously filed an income tax return with the state of Illinois. You may obtain the IL-PIN assigned to you by
- using our
IL-PIN inquiry in MyTax Illinois, or
- calling our toll-free number at 1 800-732-8866 and selecting "individual income tax" and "PIN" and following the prompts.
Be sure to have your Illinois driver's license/state ID number or prior year adjusted gross income available before you make your inquiry.
If you do not have an 8-digit IL-PIN (you are a first-time filer in Illinois), you may not file your return electronically through MyTax Illinois. However, if you have a valid driver's license, or state ID card issued by the Illinois Secretary of State, you may be able to use a tax preparer or tax software to file your return electronically. Otherwise, you must file a paper Form IL-1040.
