Estimated Payments

 
 
You must make estimated income tax payments if you reasonably expect your tax liability for the year to exceed $500 after subtracting your Illinois withholding, pass-through entity payments, and tax credits for

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

You will likely need to make estimated payments if your income is either fully or partially exempt from Illinois withholding.

For more information, refer to Form IL-1040-ES, Estimated Income Tax Payments for Individuals.
