SECTION 100.7090 RECIPROCAL AGREEMENT (IITA SECTION 701)
Section 100.7090 Reciprocal
Agreement (IITA Section 701)
a) General rule. The Director may enter into an agreement with the
taxing authorities of any state which imposes a tax on or measured by income to
provide that compensation paid in such state to residents of Illinois shall be
exempt from withholding of such tax; in such case, any compensation paid in
Illinois to residents of such state shall be exempt from withholding of
Illinois income tax. Pursuant to such reciprocal agreements, the employer in
Illinois should, upon request by an employee residing in such other state, withhold
tax on his compensation for the state of his residence. (See IITA Section 302(b)
which provides for agreements exempting compensation of nonresidents from
Illinois income tax.)
b) Example. This Section may be illustrated by the following
example: A, a resident of State X is employed by X Retail Clothing Store, an Illinois
corporation, and works each day in Chicago at X's store as a sales clerk. A's
wages are "compensation paid in Illinois" as defined in IITA Section
304(a)(2)(B). However, pursuant to a reciprocal agreement with State X, A's
compensation is not subject to withholding under the Illinois Income Tax Act. Accordingly,
X Company is not required to withhold Illinois income tax on the compensation
paid to A. However, X Company should, at A's request, withhold the State X
income tax due on A's compensation pursuant to the State X withholding
requirements on compensation paid to State X residents.
