Kentucky Inheritance Tax: Rates, Classes, and Who Actually Pays

Most people settling a Kentucky estate discover the inheritance tax late — after they have already distributed money to family members, and before they realize the personal representative can be held personally liable for any unpaid tax. That is the wrong order of operations.

Kentucky is one of only six states still levying an inheritance tax. Understanding who owes it, how much, and when to file protects both the estate and the person administering it.

Who Pays Kentucky Inheritance Tax — and Who Doesn't

Kentucky's inheritance tax is assessed against the person receiving the property, not against the estate as a whole. But the personal representative is legally responsible for filing the return and ensuring the tax is paid before assets are distributed. Both the beneficiary and the executor can be held personally liable if the tax goes unpaid.

The key is knowing which class a beneficiary falls into.

Class A — Completely Exempt

For deaths occurring after June 30, 1998, Class A beneficiaries pay zero Kentucky inheritance tax. This class includes: surviving spouses, parents, children by blood, stepchildren, adopted children, grandchildren, and siblings (including half-siblings).

The vast majority of Kentucky estates pass entirely to Class A beneficiaries. When that is the case, no inheritance tax return needs to be filed with the Department of Revenue. Instead, the fiduciary completes an Affidavit of Exemption (Form 92A300) and files it only with the District Court to facilitate the estate's final settlement. Do not send the 92A300 to the Department of Revenue — doing so creates unnecessary administrative friction without any legal benefit.

Class B — Taxable at 4% to 16%

Class B includes: nieces and nephews (by blood — not by marriage), half-nieces and half-nephews, daughters-in-law, sons-in-law, aunts, uncles, and great-grandchildren.

Class B beneficiaries receive a $1,000 exemption on inherited value. Everything above that threshold is taxed on a progressive sliding scale from 4% up to 16%.

Class C — Taxable at 6% to 16%

Class C is the catch-all for everyone else: cousins, unrelated friends, domestic partners who are not legally married, nieces and nephews by marriage, and non-exempt organizations or charities. Class C beneficiaries receive only a $500 exemption, with the remainder taxed aggressively from 6% to 16%.

Kentucky Inheritance Tax Rates in Detail

The progressive rate structure means the tax on a Class B or Class C inheritance increases as the inherited amount grows. The personal representative should calculate each beneficiary's net taxable amount (gross inheritance minus applicable exemption) before distributing any assets.

A tax professional should handle the calculation when distributions involve multiple Class B or Class C beneficiaries, or when some heirs are exempt and others are not. Mixing Class A and non-Class A beneficiaries in the same estate requires careful allocation of assets to determine each taxable share.

Filing the Kentucky Inheritance Tax Return

When any estate assets pass to Class B or Class C beneficiaries, the fiduciary must file the Kentucky Inheritance Tax Return with the Department of Revenue. Two forms are available: Form 92A200 (the comprehensive version) and Form 92A205 (the short form). The short form applies to simpler distributions; the comprehensive form handles more complex estates.

The return must be filed before assets are distributed. An executor who distributes the estate and then discovers a Class B nephew is owed a significant inheritance — and that the tax was never calculated or paid — faces personal liability to the Department of Revenue for that unpaid amount.

The 5% Discount and the Installment Option

Kentucky incentivizes prompt payment with a 5% discount if the inheritance tax is paid within nine months of the date of death. On a $50,000 taxable distribution, that discount can be meaningful — do not miss it by delaying until the estate is fully settled.

For beneficiaries with a net inheritance tax liability exceeding $5,000, the law allows an election to pay in ten equal annual installments. However, interest begins accruing 18 months after the date of death on any deferred amount. The installment option is a cash-flow tool, not a way to reduce the overall tax burden — the total paid will exceed the lump-sum amount.

When the Estate Passes to Class A Only

If every heir is a Class A beneficiary — spouse, children, parents, siblings — the process is simpler:

1. Complete Form 92A300 (Affidavit of Exemption).
2. File it with the District Court only (not the Department of Revenue).
3. The court uses it to facilitate final settlement of the estate.

No inheritance tax is owed, and no separate tax return goes to the Department of Revenue.

Common Mistakes That Create Personal Liability

Distributing before confirming beneficiary class. A fiduciary who assumes everyone is Class A without verifying can distribute the estate, then face a demand from the Department of Revenue after the estate accounts are empty.

Sending the Affidavit of Exemption to the wrong office. The 92A300 goes only to the District Court. Sending it to the Department of Revenue does not trigger a review but creates confusion in both agencies' records.

Missing the 5% discount window. The nine-month clock runs from the date of death, not from the date of estate opening or the date the fiduciary was appointed. Track the deadline from day one.

Confusing Kentucky inheritance tax with federal estate tax. The federal estate tax has an exemption of over $13 million per decedent in 2026. Most Kentucky estates owe no federal estate tax. The Kentucky inheritance tax operates entirely separately and applies at much lower thresholds.
