01.Kentucky has a state inheritance tax — but Class A heirs (immediate family) are exempt.
Kentucky is one of only a handful of states with a state inheritance tax. The rate depends on the heir's relationship to the decedent: Class A (spouse, parents, children, grandchildren, siblings) pay nothing. Class B (nieces, nephews, daughters/sons-in-law, aunts, uncles) pay 4-16%. Class C (everyone else, including charities other than qualified ones) pay 6-16%. For most KY families leaving assets to immediate family, the tax is zero.
