Florida corporate income apportionment is the method a company uses to figure out how much of its income the state can tax when it does business both inside and outside Florida. Rather than paying the 5.5 percent corporate rate on every dollar of profit, a multistate corporation applies a weighted three-factor formula built on property, payroll, and sales, and pays Florida tax only on the resulting share.1Florida Department of Revenue. Tax and Interest Rates2Florida Statutes. Florida Code 220.15 – Apportionment of Adjusted Federal Income
Which Companies Have to Apportion
Apportionment applies to corporations that conduct business both inside and outside Florida.2Florida Statutes. Florida Code 220.15 – Apportionment of Adjusted Federal Income A company that operates entirely within the state doesn’t apportion; it reports 100 percent of its net income to Florida.
The threshold question is whether the corporation has nexus with Florida, meaning a connection sufficient to give the state constitutional authority to tax it. Physical presence is the clearest trigger: an office, owned property, or employees in the state. Nexus can also arise from economic activity alone, such as substantial sales into Florida, even without any in-state employees or facilities. Companies uncertain about their obligations can request guidance from the Department of Revenue.3Florida Department of Revenue. Corporate Income Tax
When Federal Law Blocks Florida From Taxing at All
Before running any apportionment numbers, check whether Public Law 86-272 removes the corporation from Florida’s corporate income tax entirely. The federal statute prohibits any state from imposing a net income tax on a company whose only in-state activity is soliciting orders for tangible personal property, provided those orders are approved outside the state and fulfilled from outside the state.4Congress.gov. The Evolution of PL 86-272 State Income Tax Immunity for Income The protection extends to solicitation carried out by independent contractors.
The shield is narrower than most businesses assume. It covers only solicitation of orders for physical goods. Providing services in Florida, licensing software, or performing post-sale work like warranty repairs pushes the company outside the protection, and it must file and apportion like any other multistate corporation. Even a modest amount of non-solicitation activity can void the exemption, so companies relying on it should document their Florida activities carefully.
The Three-Factor Formula
Florida’s apportionment fraction combines three factors at fixed weights: sales at 50 percent, property at 25 percent, and payroll at 25 percent.2Florida Statutes. Florida Code 220.15 – Apportionment of Adjusted Federal Income The double weighting on sales means a company’s Florida customer base drives more of its tax liability than its Florida footprint, though property and payroll still count.
Each factor is a fraction: the Florida amount over the everywhere amount.
- Sales factor (50 percent): Florida sales divided by total sales. Sales generally means gross receipts, excluding interest, dividends, rents, and royalties, with exceptions for companies whose core business involves leasing property or mineral production.
- Property factor (25 percent): the average value of real and tangible personal property owned or rented in Florida, divided by the average value of such property everywhere.
- Payroll factor (25 percent): compensation paid to employees working in Florida, divided by compensation paid everywhere.
Multiply the combined fraction by adjusted federal income to get the amount Florida can tax. Adjusted federal income starts with federal taxable income and applies the Florida-specific additions and subtractions in Section 220.13.5Florida Statutes. Florida Code 220.13 – Adjusted Federal Income A $50,000 exemption is then subtracted from apportioned net income before the 5.5 percent rate is applied.6Florida Statutes.

How Sales Get Sourced to Florida
Because sales carry half the formula’s weight, the sales factor is where most of the real work happens. The sourcing rule depends on what the company sells.
Tangible Personal Property
Sales of physical goods count as Florida sales when the property is delivered or shipped to a buyer in the state, no matter where the order was placed or where the shipment started.7Florida Senate. Florida Code 220.15 – Apportionment of Adjusted Federal Income Under this destination test, a Georgia manufacturer shipping to Florida customers includes those receipts in the Florida numerator. One narrow exception applies to frozen fruit juice concentrate manufacturers classified under NAICS 311411: if the product’s ultimate destination is outside Florida, the sale is not sourced to the state regardless of the shipping point.
Financial Organization Income
Banks, investment companies, real estate investment trusts, and brokerage firms follow separate sourcing rules. Income is Florida-sourced when it comes from financial services performed in the state, trading in securities managed in the state, interest received within the state (other than interest from loans secured by out-of-state property), or rents on Florida property.7Florida Senate. Florida Code 220.15 – Apportionment of Adjusted Federal Income These rules are transaction-specific, and financial organizations generally need to work through each revenue stream individually.
What Gets Apportioned and What Gets Allocated
Not every dollar of corporate income runs through the three-factor formula. Florida separates business income, which is apportioned, from nonbusiness income, which is allocated in full to a single state. That distinction matters because allocated income either sits entirely in Florida’s tax base or entirely outside it.
Business income arises from the company’s regular trade or business operations. Nonbusiness income covers rent and royalties from real property, capital gains from property sales, interest, dividends, and patent royalties that fall outside ordinary operations. Florida allocates each category by its own rule: real property income goes to the state where the property sits, capital gains from tangible property go to the state where the property was located at sale, and interest and dividends go to the state of the taxpayer’s commercial domicile, generally the headquarters where the business is directed or managed.
Misclassifying a large item can move significant income into or out of the formula. Selling a building used in regular operations may produce business income that gets apportioned; selling an unrelated investment property may produce nonbusiness income allocated entirely to one state. Aggressive positions on this line attract audit scrutiny.
Industry-Specific Formulas
Several industries don’t use the standard three-factor formula at all. Section 220.15 defers to the special rules in Section 220.151 when they apply.8Florida Senate. Florida Code 220.151 – Special Apportionment Formulas
- Insurance companies apportion using a single fraction: direct premiums written on Florida properties and risks over direct premiums written everywhere. Companies whose primary business is reinsurance use a modified version that adds reinsurance premiums to the calculation.
- Transportation companies apportion using revenue miles in Florida over revenue miles everywhere.
- Citrus processing companies may elect to use only the sales factor instead of the three-factor formula.
The Records Apportionment Depends On
Apportionment accuracy hinges on documentation that most accounting systems don’t generate on their own. Taxpayers need records showing the destination of every shipment, the location where services are performed or received, the average value of property held in each state, and payroll broken out by work location. For the sales factor, the controlling fact is where the customer takes delivery, not where the sale was negotiated or where the invoice was sent.
Those records have to support the figures reported on Form F-1120 and its apportionment schedules.3Florida Department of Revenue. Corporate Income Tax The Department of Revenue can request backup during an audit, and reconstructing apportionment data after the fact is both expensive and unreliable. A company doing business in several states is far better off building the tracking into its accounting from the start than piecing it together at year-end.
