Providing for the apportionment of business income by the single sales factor and the apportionment of financial institution income by the receipts factor, deductions from income when using the single sales factor and receipts factor, the decrease in corporate income tax rates determining when sales other than tangible personal property are made in the state and excluding sales of a unitary business group of electric and natural gas public utilities.

HB 2336 changes how Kansas taxes business income. Starting in 2028, most businesses will use a single sales factor (based on where sales occur) to determine taxable income, replacing the current method that used sales, property, and payroll. Businesses can choose this single sales factor for 2025-2027, and financial institutions will use the sales factor for apportionment. The bill also automatically lowers corporate tax rates each year if tax receipts exceed the prior year's amount, with the reduction calculated and applied. Additionally, it excludes sales by electric and gas utility groups from certain tax rules.
