How to calculate Florida Apportionment on the Florida Department of Revenue Corporate Income Tax Return (F-1120)

Florida corporate taxpayers conducting business within and outside the state of Florida are mandated to report apportioned business income to Florida. The corporation's adjusted federal income is multiplied by a three-factor formula to calculate Florida's portion of business income. The apportionment factors are calculated on Schedule III of the F-1120 and Florida's apportionment of business income is calculated on Schedule IV of the F-1120.

Instructions

1. The first factor is the property factor. Property is defined as the average value of real and tangible personal property owned or rented. To calculate the property factor:

   (Property value in Florida / Property value outside of Florida) * 25% = property factor

2. The second factor is the payroll factor. Payroll is defined as the total wages, salaries, commissions, back pay awards and cash value of all reimbursements paid in any other form other than cash. To calculate the payroll factor:

   (Total payroll in Florida / Total payroll outside of Florida) * 25% = payroll factor

3. The third factor is the sales factor. Sales are defined as the total gross revenue from transactions and activities derived from a business or trade. To calculate the sales factor:

   (Total sales in Florida / Total sales outside of Florida) * 50% = sales factor

4. Total all these factors and this calculates the apportionment fraction.

5. Multiply the corporation's federal adjusted income by the apportionment fraction and this calculates the Florida portion of adjusted federal taxable income.
