Apportionment
How multi-state income is divided among states, usually by sales, property, and payroll factors.
In detail
California’s doing-business tests use $757,070 sales / $75,707 property / payroll or 25% of totals (2025 FTB).
Your share of a partnership’s in-state factors counts toward your own totals.
Corporations apportion net income; LLCs apportion gross receipts for the fee.
