Kentucky Estate Tax FAQs
Does Kentucky have an estate tax?
No. Kentucky does not have a state estate tax. Only the federal estate tax applies (a permanent $15M exemption per person from 2026). This makes Kentucky more favorable for estate planning compared to the 13 states that do impose a state estate tax. Probate attorney fees here follow a mid-range statutory schedule, on top of moderate court filing fees.
Does Kentucky have an inheritance tax?
Yes. Kentucky has a state inheritance tax. Class A (spouse, child, parent, grandchild): exempt. Class B (niece/nephew, aunt/uncle): 4-16%. Class C (all others): 6-16%. Only six states impose an inheritance tax, which is paid by beneficiaries rather than the estate itself.
How long does probate take in Kentucky?
Probate in Kentucky typically takes 6 to 12 months. Estates under $30,000 may qualify for a simplified small estate procedure, which is significantly faster.
How much does probate cost in Kentucky?
Court filing fees in Kentucky range from $75 to $300. Attorney fees are typically 3% of the estate value (statutory). Executor compensation is typically around 3% of the estate.
Where does Kentucky sit among states on probate filing fees?
According to PlainEstate's compiled state court fee schedules, Kentucky ranks #13 of 51 surveyed states by maximum probate filing fee (lowest max fee = #1). That ordinal matches the /rankings/lowest-probate-costs listing. See /methodology/#corpus-placement for the exact sort basis.
Can you avoid probate in Kentucky?
Yes. Common probate avoidance strategies in Kentucky include revocable living trusts, transfer-on-death (TOD) deeds for real estate, payable-on-death (POD) accounts for bank and investment accounts, and joint ownership with right of survivorship. Kentucky also offers a simplified process for small estates under $30,000.
What happened to the 2026 federal estate tax sunset, and how does it affect Kentucky residents?
The TCJA provisions were scheduled to sunset after December 31, 2025, which would have cut the federal exemption from $13,990,000 to roughly $7,000,000 per person. The One Big Beautiful Bill Act (Pub. L. 119-21), signed July 4, 2025, repealed that sunset and set a permanent $15,000,000 per-individual exemption effective January 1, 2026, indexed for inflation. Because Kentucky has no state estate tax, only the federal exemption applies, and the permanent $15,000,000 threshold means very few Kentucky estates owe federal estate tax.
