Claims to Recover Erroneously Paid Tax
Section 280
Section 280.110 Claims to
Recover Erroneously Paid Tax
a) Incorporation by Reference
In general, the provisions of Subpart N of the Service
Occupation Tax Regulations (86 Ill. Adm. Code 140) shall apply.
b) 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.
