The Illinois Department of Revenue website uses a system called Web File for electronic filing. Using this, taxpayers can file free directly through the state. Tax help is also available on the site, and you will be able to save and print your return. The system will guide you through the process, asking you for the same information you would enter on a tax form. Web File cannot be used to file a previous tax year's return or to file a return for a deceased person.
Things You'll Need
- Tax documents
- Personal identification
Find your PIN (IL-PIN) in your IL-1040 book, or click on the "Individuals" tab, then "Get Your IL-PIN" under the "File" heading. Enter your Social Security number along with one of the following: your Adjusted Gross Income (AGI) from the previous year's return, your 9-digit ZIP code, driver's license number, or Illinois state ID number. If filing jointly, enter Social Security numbers and associated information for both filers. If you are a first-time online filer without an IL-PIN, you might be able to use the system with a valid driver's license or state identification number.
Click on the "Individuals" link, then "File a Return" under the "File" link. Use the "IL-1040" link, followed by "Click Here to Web File." Use Web File to start a new return, access a previously saved return, or print an Illinois tax return you have already submitted. Have your W-2 and other tax forms nearby, and enter information in the blanks according to the prompts provided by the Web File program.
Click the "Save" button at the bottom of the page after you fill in the blanks. Keep your federal return handy if possible. Illinois Web File often gives you line item numbers from federal income tax forms 1040, 1040-A, and 1040-EZ to make it easier for you to supply the information for your state tax return. Submit your return. You will not need to mail in a paper copy or any forms, unless you want to mail a payment instead of paying your tax bill online, if you owe any money.
