You will owe a late-payment penalty for underpayment of estimated tax if you were required to make estimated payments and failed to do so, or failed to pay the required amount by the payment due date. You may be penalized even if you are receiving a refund. If your Illinois Income Tax exceeds the total tax withheld and credits by more than $1,000 for individuals, $400 for corporations, or $500 for partnerships or S corporations that elect to pay pass-through entity-level tax, you may have been required to make estimated payments. The late-payment penalty amount is based on the number of days the payment is late. Payments less than 31 days late are penalized at 2% of the amount due, and payments 31+ days late are penalized at 10% of the amount due. For more information, refer to Form IL-2210, Computation of Penalties for Individuals; Form IL-2220, Computation of Penalties for Businesses; and Publication 103, Penalties and Interest for Illinois Taxes.
