Inheriting a retirement account—whether a Traditional IRA, Roth IRA, or 401(k)—is often a bittersweet experience. While the windfall can provide financial security, navigating the distribution rules and tax implications requires careful attention.
Changes from the SECURE Act 1.0 and 2.0 significantly shifted how inherited accounts are treated. The strategy depends on your relationship to the deceased, whether the account holder had already reached their Required Minimum Distribution (RMD) age, and the type of account involved.
1. The Starting Line: Who Are You to the Deceased?
The IRS divides beneficiaries into three distinct categories, and your rules depend heavily on which group you fall into.
A. Surviving Spouses (Maximum Flexibility)
Spouses have the most options when inheriting retirement assets. A surviving spouse can:
-
Roll the assets into their own IRA: Treats the funds as if they were theirs all along. RMDs are delayed until the surviving spouse reaches their own RMD age.
-
Maintain an Inherited IRA: Useful if the surviving spouse is under age 59½ and needs access to the cash, as withdrawals from an inherited IRA avoid the 10% early withdrawal penalty.
-
Take a lump-sum distribution: Immediate liquidity, though subject to ordinary income tax on traditional assets.
B. Eligible Designated Beneficiaries (EDBs)
Certain non-spouse beneficiaries are permitted to “stretch” distributions across their own single life expectancy rather than emptying the account quickly:
-
Minor children of the deceased (up to age 21, at which point the 10-year rule triggers).
-
Disabled or chronically ill individuals.
-
Beneficiaries who are not more than 10 years younger than the deceased account owner.
C. Non-Eligible Designated Beneficiaries (Most Adult Children & Relatives)
Most adult heirs (such as adult children, grandchildren, or siblings) fall into this category. Under the 10-year rule, the entire account balance must be fully distributed by December 31 of the 10th year following the account owner’s death.
2. The 10-Year Rule: How Distributions Work
If you are subject to the 10-year rule, how you withdraw the money depends on whether the original account owner had reached their Required Beginning Date (RBD) for RMDs:
| Owner Died… | Annual RMD Requirement | Account Depletion Deadline |
| Before RMD Age | No required annual withdrawals during Years 1–9. You can wait and take it all in Year 10 or spread it out. | December 31 of the 10th year following death. |
| On or After RMD Age | Must take annual RMDs in Years 1–9 based on your life expectancy. | Entire remaining balance emptied by Year 10. |
3. Traditional vs. Roth Inherited Accounts
Tax treatment varies significantly depending on the account type:
-
Inherited Traditional IRA / 401(k): Distributions are taxed as ordinary income in the year you receive them. If you withdraw a large sum in a single tax year, it could push you into a higher federal and state income tax bracket.
-
Inherited Roth IRA / 401(k): Withdrawals are generally 100% tax-free, provided the original Roth account met the 5-year aging rule. Because growth is tax-free, it often makes sense to leave inherited Roth funds inside the account until Year 10 to maximize growth before taking the full balance.
4. Key Rules at a Glance
-
No Early Withdrawal Penalty: Inherited accounts are exempt from the 10% early withdrawal penalty regardless of your age, though standard income taxes still apply to traditional balances.
-
No New Contributions: You cannot make additional contributions to an inherited IRA or 401(k).
-
Disclaiming Assets: If receiving the inheritance would trigger unwanted tax burdens, you can legally disclaim (refuse) the assets within 9 months of the date of death. The funds then pass to the contingent beneficiaries.
Next Steps
Before taking a distribution, review your current tax year projection to avoid unintended tax spikes. Spreading distributions across multiple tax years during the 10-year window is often a practical way to manage the income tax impact.
