Individual Income Tax Login Functions

(Require a MyTax Illinois Account)

In most cases, MyTax Illinois users can log in to file returns for any of the last three tax years. However, if the original return was filed using a paper return, or if the taxpayer is changing his or her filing status (e.g., from married filing jointly to married filing separate), then the taxpayer must file Form IL-1040-X using a paper return.

To file a return: Log in to your MyTax Illinois account. (Joint filers — log in to the account of the primary taxpayer.) Select “File a Return,” and choose the year of the return you wish to file.

To view a return: Log in to your MyTax Illinois account. (Joint filers — log in to the account of the primary taxpayer.) Select “View more account options.” Then, under the panel for “Periods and Submissions,” select ‘View account periods.” Select the tax filing period you wish to view. Then, select the hyperlink for the processed return in the Period Activity Panel.

To amend a return: Log in to your MyTax Illinois account. (Joint filers — log in to the account of the primary taxpayer.) Select “View more account options.” Then, under the panel for “Periods and Submissions,” select ‘View account periods.” Select the tax filing period you wish to amend. Select “File or Amend a Return,” and then choose the link “Amend.”

You can make payments in a number of ways using MyTax Illinois, and you can do so using checking or savings accounts. To pay assessed balances, you can use “Manage Payments and Returns.” To make estimated and extension payments (i.e., IL-1040-ES and IL-505-I payments), choose “View more account options,” and use the links for estimated and extension payments. If you are filing a tax return with a payment due, you will have the option to include payment information when filing the return.

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.

You can use your MyTax Illinois logon to respond to some notices. Select “View more account options,” and then “Respond to a notice” in the Letters and Messages panel.

Select “respond” in the row of the notice to which you would like to respond. Responses in MyTax Illinois are immediately logged on your account. You can view your submitted responses in MyTax Illinois by selecting “View more account options” and then “View Account Messages” in the “Letters and Messages” panel. The response will be in the Outbox tab in Messages. IDOR reviews these responses on a first in, first out basis. Once your correspondence is reviewed, we will mail you a notice explaining the outcome of the review. You can view this notice in MyTax Illinois by selecting “View more account options” and then “View Account Letters” in the “Letters and Messages” panel. While you are not actively being billed for any balance corresponding to the notice during the time that you are waiting for a review of your correspondence, a balance due may still display in MyTax Illinois.

For certain notices issued to taxpayers by the Federal State Exchange Unit at IDOR, we allow the taxpayer the option of sending a response using MyTax Illinois. To send a response to such a notice, log in to your MyTax Illinois account, and select “More Account Options” for the account type for which the notice was sent. Under the panel “Account Options,” select the link “Respond to an Examination.”

Please see your Examination notice for specific instructions. For assistance with how to respond to an examination, please contact REV.FSEU@illinois.gov or 217 782-7962.

For certain audit notices issued to taxpayers by IDOR, we allow the taxpayer the option of sending a response using MyTax Illinois. To send a response to such a notice, log in to your MyTax Illinois Account, and select “More Account Options” for the account type for which the notice was sent. Under the panel “Account Options,” select the link “Respond to Audit.’

Please see your audit notice for specific instructions. You can contact your auditor with questions or assistance with how to respond to a notice.

You can use your MyTax Illinois account to submit Form CPP-1, Installment Payment Plan Request, electronically, when certain conditions are met.

Log in to your account, and select “More….” Under the panel “Payments and Returns,” choose “Set up a Payment Installment Plan with IDOR.” For assistance with your payment plan, please contact Rev.PayPlan@illinois.gov, 217 785-8556, or the number on your most recent collection notice.

Note: You must have a balance due that is actively in collection with IDOR to use MyTax Illinois to submit your payment plan request. If you have only received your final notice of tax due from IDOR or if you have not yet been billed for any outstanding balances, you cannot use MyTax Illinois to submit your request for a payment plan.
