86 Ill. Adm. Code 690.110
Claims to Recover Erroneously Paid Tax
Section 690
Section 690.110Â Claims to
Recover Erroneously Paid Tax
Claims for Multiple Taxes. If a
claimant files a claim for refund on a transaction which was subject to State
and local taxes administered by the Department, the claim need not be filed
separately for each type of tax. A single claim for the total of all
applicable taxes will suffice. The claim will be audited, heard, or otherwise
processed as a single claim whenever possible. A single credit memorandum will
be issued which may be used by the claimant or his authorized assignee to pay
State or local tax liability.
