When I help clients plan their estates, one question comes up often: “Are retirement plans included in the gross estate?” The answer is not straightforward. Retirement accounts like 401(k)s, IRAs, and pensions may or may not be part of your taxable estate, depending on beneficiary designations, account types, and tax laws. In this article, I break down the rules, exceptions, and strategies to minimize estate taxes on retirement assets.

Understanding Gross Estate Under U.S. Tax Law
The gross estate includes all assets a person owns at death. The IRS defines it under 26 U.S. Code § 2031. Retirement plans often fall into this category, but exceptions exist.
What Counts as a Retirement Plan?
- Traditional IRAs & 401(k)s – Tax-deferred accounts.
- Roth IRAs & Roth 401(k)s – Funded with after-tax dollars.
- Pensions & Annuities – Employer-sponsored plans.
- SIMPLE & SEP IRAs – Small business retirement accounts.
When Are Retirement Plans Included in the Gross Estate?
1. Account Ownership & Beneficiary Designations
If you are the primary owner of a retirement account, the full balance is included in your gross estate—even if you named a beneficiary.
Example:
- John has a $500,000 IRA.
- He names his daughter as the beneficiary.
- At his death, the full $500,000 is part of his gross estate.
2. Spousal Inheritance Rules
If a spouse is the sole beneficiary, they can roll over the funds into their own IRA, deferring estate tax until their death.
Example:
- Susan inherits her husband’s $1M 401(k).
- She rolls it into her IRA.
- The $1M is not taxed in her husband’s estate but will be in hers later.
3. Non-Spouse Beneficiaries & the 10-Year Rule
Under the SECURE Act (2019), most non-spouse beneficiaries must withdraw all funds within 10 years. The account value at death is included in the estate.
Example:
- David leaves his $750,000 IRA to his son.
- The $750,000 is part of David’s gross estate.
- His son must empty the account within 10 years, paying income tax on withdrawals.
4. Trusts as Beneficiaries
If a trust is named the beneficiary, the retirement account may or may not be included in the estate, depending on the trust’s structure.
Key Factors:
- Revocable Trusts – Included in the estate.
- Irrevocable Trusts – May avoid estate inclusion if properly structured.
How Estate Tax Applies to Retirement Plans
The federal estate tax exemption for 2024 is $13.61 million per individual (IRS Rev. Proc. 2023-34). If your estate exceeds this, retirement accounts could push you into taxable territory.
Calculating Estate Tax on Retirement Accounts
The estate tax rate is 40% on amounts above the exemption.
Example Calculation:
- Estate Value: $15M
- Retirement Accounts: $2M
- Taxable Amount: $15M - $13.61M = $1.39M
- Estate Tax Due: $1.39M * 0.40 = $556,000
State Estate Taxes
Some states (e.g., Oregon, Massachusetts) have lower exemptions. A $5M IRA could trigger state estate taxes even if federal taxes don’t apply.
Strategies to Minimize Estate Taxes on Retirement Plans
1. Roth Conversions
Converting a traditional IRA to a Roth IRA means paying income tax now but eliminating future RMDs and reducing estate tax exposure.
Example:
- Convert $500k IRA → Roth IRA.
- Pay $185,000 in taxes (37% bracket).
- The $500k grows tax-free and is not included in the estate.
2. Charitable Remainder Trusts (CRTs)
- Donate retirement assets to a CRT.
- Avoid estate tax and receive a charitable deduction.
3. Stretch IRA Strategies (Pre-SECURE Act)
Before 2020, beneficiaries could “stretch” IRA distributions over their lifetime. Now, only eligible designated beneficiaries (minor children, disabled individuals) qualify.
4. Life Insurance Trusts (ILITs)
Use IRA distributions to fund a life insurance policy held in an irrevocable trust, keeping proceeds out of the estate.
Comparison: How Different Retirement Accounts Are Treated
| Account Type | Included in Gross Estate? | Taxation on Withdrawals |
|---|---|---|
| Traditional IRA | Yes | Ordinary Income Tax |
| Roth IRA | Yes (but tax-free growth) | Tax-Free |
| 401(k) | Yes | Ordinary Income Tax |
| Pension | Yes (if beneficiary is estate) | Ordinary Income Tax |
Final Thoughts
Retirement plans are usually included in the gross estate, but smart planning can minimize tax burdens. Strategies like Roth conversions, trusts, and charitable giving can help preserve wealth for heirs. If your estate nears the federal exemption limit, consult an estate attorney to optimize your plan.
