SECTION 100.3310 BUSINESS INCOME OF PERSONS OTHER THAN RESIDENTS (IITA SECTION 304) – IN GENERAL

Section 100.3310  Business Income

of Persons Other Than Residents (IITA Section 304) – In General

The business income of a person other

than a resident is allocated to Illinois if such person's business income is

derived solely from Illinois. Note that any reference to person in this section

shall refer to a person other than a resident. Every person who derives business

income from Illinois and one or more other states must apportion such business

income between Illinois and such other state or states in accordance with the

provisions of IITA Section 304. Special apportionment rules are provided for

the business income of insurance companies, financial organizations, and

persons furnishing transportation services, and for alternative methods of apportionment

(and allocation) where the specific statutory provisions do not fairly

represent the extent of a person's business activity in Illinois. See IITA

Section 304(b),(c),(d) and (e) of the Act.
