What are estimated payments and how do I make them for individual income tax?

Page Content

You must make estimated income tax payments if you reasonably expect your tax liability to exceed $1,000 after subtracting your Illinois withholding, pass-through withholding, and tax credits for

• income tax paid to other states,
• Illinois Property Tax paid,
• education expenses,
• the Volunteer Emergency Worker Credit,
• the Earned Income Credit, and
• Schedule 1299-C, Income Tax Subtractions and Credits (for individuals).

You are likely to meet this requirement if your income is either fully or partially exempt from Illinois withholding. If you plan to file a joint income tax return, you must figure your estimated tax on the basis of your joint income. Payments may be made electronically through MyTax Illinois or via mail by using Form IL-1040-ES. For more information, refer to Form IL-1040-ES, Estimated Income Tax Payments for Individuals.

You can view the amounts of estimated payments you have made by visiting our IL-1040-ES Payment Inquiry application and entering the primary Social Security Number and first four letters of the last name.
