You must make estimated income tax payments if you can reasonably expect your tax liability to exceed $500.00 after subtracting your withholding, credits for Illinois Property Tax paid, income tax paid to other states, Education Expense credit, Earned Income Tax credit, and tax credits from
Schedule 1299-C. 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. For more information, refer to
Form IL-1040-ES, Estimated Income Tax Payments for Individuals.
