Closing and opening tax accounts

You can use MyTax Illinois to add new tax registrations. After logging in to MyTax Illinois, choose “More…,” and then under the “Registration Information” panel, select “Register for New Tax accounts.” You can also select “Reopen Closed Accounts” if you need to register again for a tax account type that you had previously closed.

To request to close a tax account, next to the account on the Summary screen, choose “More account options,” and under the “Account Maintenance” panel, choose “Request to close account.”

Note: Businesses registered as Sole Proprietors must contact Central Registration for assistance in registering for additional tax accounts.

For questions about opening and closing tax accounts, please contact Central Registration at or 217 785-3707.
