Calculating KY Corporate Income Tax

There are three steps involved in calculating Kentucky Corporate Income Tax.

1)	Make Kentucky adjustments to Federal taxable income.
	Kentucky’s corporate income tax calculation starts with federal taxable income as reported on a business’s federal tax return. Then that income is adjusted according to Kentucky’s specific tax laws. Kentucky’s laws require some amounts to be added to federal income and some amounts to be subtracted. For example, federal law includes amounts received as dividends in a company’s taxable income. Kentucky does not tax such dividend income, so the amount of dividends received is subtracted from a company’s federal income. On the other hand, the IRS allows companies to deduct the amount they pay in state income taxes; Kentucky requires those amounts to be added back. After all the various additions and subtractions, a company arrives at Kentucky net income.
2)	Apportion net income to Kentucky.
	Kentucky only taxes a business on the portion of its net income that was generated by its business activity in Kentucky. To figure Kentucky's portion, Kentucky net income is multiplied by an apportionment factor. For most companies that do business in Kentucky, that formula is calculated by taking the amount of receipts derived from its business activity in Kentucky and dividing it by the amount of receipts derived from its business activity everywhere. (Certain types of companies must use different apportionment formulas, depending on the industry in which they operate). The apportionment factor is then multiplied by Kentucky net income to derive Kentucky taxable net income. (Certain other types of income generated by intangible assets sited in Kentucky may get allocated to Kentucky and be included in taxable net income.)
3)	Multiply taxable net income by the tax rate.
	After subtracting any net operating loss carryforwards from taxable net income, the taxpayer calculates its tax due by multiplying taxable net income by the Kentucky tax rate. Kentucky's current tax rate is a flat 5%. The total tax due may be reduced by various tax credits offered by the state to arrive at the business's net income tax liability.

Calculating KY Limited Liability Entity Tax (LLET)

Kentucky imposes a tax on every business that is protected from liability by the laws of the state. This includes corporations, LLCs, S-Corporations, limited partnerships, and other types of businesses. It does not include sole proprietorships and general partnerships because these types of businesses do not have limited liability. (There are also some types of businesses that are statutorily exempt from the LLET).

There are three steps involved in calculating the LLET.

1)	Calculate Kentucky gross receipts and Kentucky gross profits.
	The amount of LLET is based on the amount of business a company does in Kentucky. This is measured by the company's Kentucky gross receipts or its Kentucky gross profits. Kentucky gross receipts is calculated by figuring the total receipts earned in the state after returns and allowances. A pass-through entity also reduces its Kentucky gross receipts by the share of those receipts allocable to any tax-exempt organizations. A company then subtracts the Kentucky share of its cost of goods sold from its Kentucky gross receipts to derive Kentucky gross profits. Only companies in certain economic sectors (manufacturing, producing, wholesaling, retailing, and reselling of tangible products) are allowed to deduct cost of goods sold from their Kentucky gross receipts. Kentucky's definition of cost of goods sold also differs from the federal definition, so certain costs cannot be included in Kentucky cost of goods sold.
2)	Calculate total gross receipts and total gross profits.
	There is a small-business exemption to the LLET based on a business's amount of total gross receipts or total gross profits. Total gross receipts includes receipts from all business activities everywhere, adjusted for returns and allowances. Companies operating in the economic sectors that are allowed to subtract cost of goods sold subtract costs from gross receipts to derive total gross profits. If either total gross receipts or total gross profits amounts to $3 million or less, then the company just pays a $175 minimum LLET.
3)	Multiply Kentucky gross receipts and Kentucky gross profits by the applicable tax rate.
	If a business does not qualify for the small-business exemption and has total gross receipts or total gross profits in excess of $6 million, it multiplies its Kentucky gross receipts by 0.095% and its Kentucky gross profits by 0.75% to figure its LLET liability. (If total gross receipts or total gross profits falls between $3 million and $6 million, a sliding-scale formula is applied to the amount to calculate the LLET liability). The company then pays the smaller of the amount calculated on gross receipts or the amount calculated on gross profits. If a company also owes Kentucky corporate income tax, it is allowed to reduce its income tax liability by the amount of its LLET liability less the minimum $175.
