How to change your address for Illinois state taxes
To change the address on your Illinois taxes, go through the Illinois Department of Revenue — the options are below. Do it separately from the IRS, though: updating your Illinois address does not change your federal record, so you’ll also need to file Form 8822 with the IRS.
What are your options with the Illinois Department of Revenue?
- File Form IL-1040 / IL-1040-X (address auto-updates on filing)
- MyTax Illinois (online)
- By phone (800-732-8866)
Official source: Illinois Department of Revenue — change of address. If you have not yet filed, your address updates automatically when you file IL-1040 or IL-1040-X. IDOR warns that most of its mail is NOT forwarded by USPS even if you set up forwarding, so updating directly matters.
Don’t forget the IRS — this is the part we handle
Federal taxes are separate from Illinois. The IRS keeps its own address for your notices and refunds, and for individuals the only way to update it is Form 8822 — by mail, with no online option. That’s the errand we take off your plate, nationwide.
Fill the federal Form 8822 online in about a minute, sign on screen, and we mail it to the correct IRS office — Certified, with tracking. (For your Illinois change, use the official link above; we don’t file state forms.)
