Make a payment

You can make payments in a number of ways using MyTax Illinois, and you can do so using checking or savings accounts. To pay an outstanding assessed balance, you can use “Manage Payments and Returns” on the Summary screen in MyTax Illinois or you can select the applicable item on the Action center screen.

Certain account types offer links to make specific payment types (e.g., “Make an IL-501 Payment” for Illinois Withholding Income Tax). To direct a specific type of payment for a particular tax reporting period select “More account options” and then “View Account Periods.” After selecting the period for which you need to make a payment, select “Make a Payment” and indicate the type of payment you want to make, along with the payment details.

If you are filing a tax return with a payment due, you will have the option to ‘Proceed to payment’ after submitting the return request. MyTax Illinois also offers the option to “pay by mail” for several payment types. This will generate a voucher that you can print and mail with your payment.

Note: Payment requests submitted in MyTax Illinois take three to five business days to fully post to your account and for the balance to be updated.
