Kentucky
Reviewed July 2026Federal §453 conformity
Yes — Kentucky starts from the federal return and taxes installment gain as payments arrive at a flat rate that keeps falling: 3.5% for 2026, with further half-point cuts scheduled whenever the state's revenue triggers are met. Like North Carolina, the calendar works for the installment seller here — a payment received three years from now may simply face a lower rate than the same dollar today.
Nonresident sourcing
Gain from Kentucky real estate or a business operating in Kentucky is Kentucky income for sellers anywhere, and the payments keep that character; intangible gain generally follows the seller home.
Withholding
Kentucky imposes no closing-table withholding on nonresident real estate sellers. The compliance obligation sits at the entity: pass-throughs withhold on nonresident owners' Kentucky income or fold them into a composite filing — every year the entity recognizes installment gain — unless the PTE election covers it.
Selling, then moving (residency change)
Kentucky-source gain stays taxable here after a move; other gain travels with the seller, and no rule accelerates deferred gain at the border. With a 3.5% falling rate, Kentucky is more destination than departure in these plans.
Pass-through entity (PTE) tax election
Kentucky's PTE election is available at the flat individual rate with owner credits, made annually — the familiar keep-the-entity-alive logic applies for the life of the note. Separate from the election, and easy to miss: Kentucky's limited liability entity tax rides every pass-through with Kentucky receipts regardless of any election, computed on gross receipts or gross profits. It is usually small, but on a large asset sale flowing through the entity, run the LLET number before assuming it rounds to nothing.
Estate and IRD
Kentucky has no estate tax but keeps an inheritance tax that turns entirely on the recipient: spouses, children, grandchildren, parents, and siblings (Class A) take free of it, while nieces, nephews, and in-laws (Class B) owe 4% to 16% above small exemptions, and unrelated beneficiaries (Class C) owe 6% to 16% above almost none. An installment note routed to a Class A heir passes clean; the same note left to a niece or a family friend hands Kentucky up to 16% of its value. Map the beneficiaries before the estate plan is signed, not after.
Planning notes
Kentucky's list: treat the falling rate as a modest bonus for deferral, run the LLET computation on the entity before assuming the state-tax story ends at 3.5%, make the PTE election year by year, and route the note's inheritance with the class list in hand — the difference between Class A and Class C is the difference between zero and 16%.
Kentucky exempts spouses, lineal family, and siblings from its inheritance tax — but nieces, nephews, in-laws, and unrelated beneficiaries owe up to 16% of the note's value above minimal exemptions. Route the note in the estate plan with the class list open.
Kentucky's limited liability entity tax applies to pass-throughs on a gross-receipts or gross-profits base independent of any PTE election. On a large entity-level sale, check whether the proceeds enter the LLET base before calling the state cost 3.5% and done.
