86 Ill. Adm. Code 100.5240
Claims for Credit of Overpayments
Section 100
Section 100.5240 Claims for
Credit of Overpayments
a) In general. If a taxpayer becomes a member of a combined
group during a common taxable year, any requested credit carryforward shown on
its separate return for the taxable period ending with its entry into the
combined group shall be credited against the combined liability, and the
designated agent shall claim this credit on the combined return, for the
taxable year in which the member joins the combined group. A taxpayer that
leaves a combined group may not claim a credit shown on a combined return against
its separate tax liability in a subsequent taxable year. When an election is
revoked, any claim for credit shown on the last combined return shall be
credited against the separate liabilities of the electing members in the manner
designated by the designated agent that is satisfactory to the Department. The
manner designated will be satisfactory to the Department if it does not
jeopardize the collection of any liability.
b) Examples. The provisions of this Section may be illustrated
by the following examples:
1) Example 1. Corporation P and S-1 file a combined return in
1985. S-2 becomes an eligible member on January 1, 1986. S-2's 1985
overpayment of tax which it elected to be credited to 1986 shall be utilized
against the combined 1986 liability.
2) Example 2. The 1985 combined return of P, S-1 and S-2 shows
an overpayment which the designated agent elects as a credit against its 1986
liability. If S-2 leaves the combined group during 1986 it does not share in
the overpayment credit.
