Schedule G (IL-1040) — officially titled “Voluntary Charitable Donations” — is a supplemental form used by Illinois taxpayers who wish to donate part of their tax refund (or add to the amount owed) to specific charitable funds designated by the Illinois Department of Revenue. When you file your state income tax return using Form IL-1040, you may choose to support a variety of approved causes, such as wildlife preservation, Alzheimer’s research, hunger relief, and more.
The form makes it simple for Illinois residents to give back directly through their tax return. Each fund listed on Schedule G (IL-1040) supports local and statewide nonprofit initiatives that are officially recognized by the state government. Contributions must be whole-dollar amounts ($1 or more), and any donation you make reduces your refund or increases your total payment due.
Even if you are not receiving a refund, you can still make a contribution by sending the additional payment with your tax return. Donations are voluntary and will be distributed to the chosen funds in accordance with the Illinois Income Tax Act.
