How to Avoid Kentucky Inheritance Tax on an Inherited IRA: The 36-Month Annuity Rule

Under KRS 140.063, an inherited IRA or 401(k) in Kentucky is completely exempt from the state inheritance tax if the funds are distributed as a series of substantially equal periodic payments over at least 36 months. If the beneficiary instead takes a lump-sum distribution — withdrawing the entire account at once — the full balance is subject to Kentucky inheritance tax at rates up to 16%. This rule applies to Class B and Class C beneficiaries: nieces, nephews, aunts, uncles, cousins, friends, and anyone other than the deceased's spouse, parents, children, grandchildren, or siblings. For a $200,000 IRA passing to a niece, the difference between a lump-sum withdrawal and a structured annuity payout is roughly $30,000 in Kentucky inheritance tax. This page explains exactly how the rule works, what documentation the Kentucky Department of Revenue requires, and how to make the right distribution decision before the money leaves the account.

The Financial Difference in Concrete Terms

The following example uses the Class B progressive rate table with a $1,000 exemption:

Scenario: $200,000 IRA inherited by a niece (Class B beneficiary)

The annuity payout still subjects the distributions to federal and Kentucky income tax as ordinary income — the inheritance tax exemption is separate from income tax treatment. But the inheritance tax savings are substantial and immediate.

Scenario: $50,000 IRA inherited by a friend (Class C beneficiary)

Who This Applies To (and Who It Does Not)

This rule matters for:

• Nieces, nephews, and half-nieces/nephews (Class B)
• Daughters-in-law and sons-in-law (Class B)
• Aunts, uncles, and great-grandchildren (Class B)
• Cousins, great-nieces, great-nephews (Class C)
• Unrelated friends and unmarried partners (Class C)
• Non-exempt organizations named as IRA beneficiaries

This rule does not apply to Class A beneficiaries — surviving spouses, parents, children, stepchildren, grandchildren, siblings, and half-siblings are fully exempt from Kentucky inheritance tax on all assets, including retirement accounts. The lump-sum vs. annuity decision has no inheritance tax consequence for them.

Exactly What "36-Month Annuity" Means Under KRS 140.063

The Kentucky statute does not require an annuity contract or an insurance product. It requires that the funds be distributed as "substantially equal periodic payments" for a "minimum period of 36 months" following the date of death. In practice this means:

• The account custodian (the financial institution holding the IRA or 401(k)) distributes the balance in regular installments — monthly, quarterly, or annually — spread over at least three years
• The payments must be substantially equal — you cannot take 95% in month one and call it a payment schedule
• The 36-month clock starts from the date of death, not the date the beneficiary submits a distribution request

Most IRA custodians have a process for setting up this payment schedule. The key step is requesting it explicitly and confirming with the custodian that the distribution plan meets Kentucky's 36-month requirement before any funds are withdrawn.

Documentation the Kentucky Department of Revenue Requires

Under KRS 140.063(4), the Kentucky Department of Revenue will not grant the inheritance tax exemption without documentation from the account custodian confirming that the funds are being distributed as a qualifying periodic payment. Specifically:

• A letter or statement from the financial institution confirming the annuity schedule
• Confirmation that the distribution period is at least 36 months from the date of death
• The total account balance as of the date of death (needed for the inheritance tax return regardless of the distribution method chosen)

If this documentation is not provided with the inheritance tax return, the Kentucky Department of Revenue treats the full account balance as a taxable lump-sum distribution and calculates the inheritance tax accordingly. The burden of proof for the exemption is on the beneficiary or executor.

The Timing Problem: This Decision Must Be Made Before the Money Moves

The most common and expensive error is submitting a distribution request to the IRA custodian without knowing this rule exists. Once a lump-sum withdrawal has been processed, the funds are gone from the account and the distribution is fixed. There is no way to retroactively restructure a completed lump-sum withdrawal into an annuity payout for Kentucky inheritance tax purposes.

The executor or beneficiary must:

1. Identify the retirement account balance and the beneficiary's class before any distribution request is made
2. If the beneficiary is Class B or C, calculate the inheritance tax under both scenarios
3. Contact the custodian to discuss setting up a 36-month payment schedule if the tax savings justify it
4. Document the payment schedule before submitting the inheritance tax return

The 9-month early-payment discount for the inheritance tax adds pressure here. If the retirement account is to be paid out over 36 months, the inheritance tax on other (non-exempt) assets in the estate may still qualify for the 5% early-payment discount — but only if paid within nine months. The executor needs to track which assets generate a current tax liability and which are deferred under the annuity structure.

Why Immediate Liquidity Often Wins Anyway

The annuity rule creates a genuine tradeoff. A beneficiary who needs the money now — to pay for the deceased's outstanding debts, to cover funeral costs, or simply because they need the funds — may rationally choose the lump-sum route and pay the inheritance tax. The question is whether the tax cost is accounted for in that decision.

The wrong outcome is taking a lump-sum distribution without knowing the tax consequence and then being surprised by a $30,000 notice from the Kentucky Department of Revenue months later. The right outcome — whichever direction the beneficiary chooses — is making the decision with full awareness of the tradeoff.

Interaction with Federal Income Tax

The 36-month annuity structure eliminates Kentucky inheritance tax but has no effect on federal or state income tax treatment. Distributions from traditional IRAs and 401(k)s are taxable as ordinary income regardless of how they are structured. Under the SECURE Act 2.0, most non-spouse beneficiaries of inherited IRAs must fully distribute the account within 10 years — the 36-month minimum for Kentucky inheritance tax purposes sits well inside that 10-year federal window.

Roth IRA distributions are generally federal-income-tax-free to beneficiaries, which makes the 36-month annuity rule even more compelling for inherited Roth accounts: structuring distributions over 36 months eliminates Kentucky inheritance tax while the distributions themselves carry no federal income tax liability.

Who This Is NOT For

• Class A beneficiaries — there is no inheritance tax regardless of how the retirement account is distributed
• States other than Kentucky — this is a Kentucky-specific rule under KRS 140.063. Other inheritance tax states (Maryland, Nebraska, New Jersey, Pennsylvania, Iowa — which is phasing out its tax — and Kentucky) have different rules
• Beneficiaries inheriting non-retirement assets — the annuity rule applies specifically to qualified retirement accounts (IRAs, 401(k)s, 403(b)s). It does not apply to inherited brokerage accounts, real estate, or cash

Frequently Asked Questions

Does the 36-month rule apply to Roth IRAs as well as traditional IRAs? Yes. KRS 140.063 applies to both traditional and Roth IRAs, as well as employer-sponsored retirement plans. The inheritance tax treatment is the same regardless of the account type.

What if the beneficiary is already past the 9-month early-payment discount deadline? If the retirement account is being distributed under the annuity structure (inheritance-tax-exempt), there is no inheritance tax due on that asset — the 9-month discount is irrelevant for that piece of the estate. The discount deadline still applies to other taxable assets in the estate.

Can the executor require a Class B beneficiary to take the annuity structure to preserve the 5% discount on other estate assets? The executor has a duty to minimize tax liabilities where possible, but generally cannot force a specific distribution arrangement on a beneficiary without their consent. The practical resolution is explaining the tax consequences clearly so the beneficiary can make an informed decision.

What if the IRA custodian is in another state? The location of the custodian is irrelevant. Kentucky inheritance tax applies based on the residence of the deceased or the location of the property passing through the estate. A Kentucky resident's IRA held at a brokerage in New York is still subject to Kentucky inheritance tax.

Does Kentucky also impose income tax on inherited IRA distributions? Yes. Distributions from traditional IRAs are subject to Kentucky income tax at the state flat rate (3.5% effective January 1, 2026). This is separate from and in addition to any inheritance tax analysis. Roth IRA distributions are generally income-tax-free.

What form reports the IRA on the inheritance tax return if the annuity exemption is claimed? The full date-of-death value of the retirement account is reported on Form 92A200 or 92A205. The exemption is claimed on the return with supporting documentation from the custodian confirming the 36-month annuity payout structure. The Department of Revenue reviews this documentation and removes the account value from the taxable calculation.
