Tax
Multi-state Apportionment
Quick definition
Formula for dividing a company's income across states for state income tax purposes, typically based on sales, payroll, and property.
Apportionment determines how much of your total income each state can tax. Most states use a single-sales-factor formula (% of sales in that state ÷ total sales = % of income taxed in that state). A few still use three-factor (sales, payroll, property). Critical for multi-state businesses: done wrong, you can be double-taxed (or pay less than you owe and face audit penalties).
