Illinois Administrative Code
Title 86 - REVENUE
Part 100 - INCOME TAX
Subpart M - BUSINESS INCOME OF PERSONS OTHER THAN RESIDENTS
Section 100.3360 - Payroll Factor (IITA Section 304)
Current through Register Vol. 48, No. 38, September 20, 2024
a) In general
b) Denominator. The denominator of the payroll factor is the total compensation paid everywhere during the tax period. Accordingly, compensation paid to employees whose services are performed entirely in a state where the employer is immune from taxation, by Public Law 86-272 for example, is included in the denominator of the payroll factor. Example: A corporation has employees in its state of legal domicile (State A) and is taxable in State B. In addition the corporation has other employees whose services are performed entirely in State C where the corporation is immune from taxation by Public Law 86-272. As to these latter employees, the compensation will be assigned to State C where their services are performed (i.e., included in the denominator - but not the numerator - of the payroll factor) even though the corporation is not taxable in State C.
c) Numerator. The numerator of the payroll factor is the total amount paid in this State during the tax period by the employer for compensation. The tests in IITA Section 304(a)(2) to be applied in determining whether compensation is paid in this State are derived from the Model Unemployment Compensation Act.
d) Compensation paid in this State. The term "compensation paid in this State" is explained in Section 100.3120 of this Part.
