If you have not yet filed your tax return, your address will be automatically updated when you file your Form IL-1040 or IL-1040-X. Make sure to include your updated address in the Personal Information section of the form.
You can update your address yourself if you have a MyTax Illinois account for Individual Income Tax. To create an account, you must have a recent bill or notice from the Department of Revenue.
If you need to update your address but have already filed your return, you may call our Taxpayer Assistance Division at 1-800-732-8866. To complete the address update, you will need to verify tax information from your account with our representative. Please call with a copy of your previously filed IL 1040 tax return or with a notice you received.
Please be aware most mail from the Illinois Department of Revenue is not forwarded by the US Postal Service, even if you have a forwarding address. This is for your protection. Please update your address with us if you have moved after you file your tax return.
