What Happens to Your 401K and IRA When You Die

You have spent decades building your retirement savings. Your 401(k), IRA, Roth IRA, maybe a pension — all carefully contributed to over the course of your career. But here is a question that most people never think to ask: what actually happens to those accounts when you die?

The answer has major implications for your family — not just how much they receive, but when, how, and how much they will owe in taxes. And the rules changed significantly with recent federal legislation, making this more complicated than it used to be.

Let us walk through it clearly.

The Most Important Thing: Beneficiary Designations

Before we get into the details of different account types, you need to understand one critical concept: retirement accounts pass to your beneficiaries based on the beneficiary designation form you filed with the account provider — not based on your will.

Read that again. Your will does not control who gets your 401(k) or IRA. The beneficiary form does.

Your will and your beneficiary designations are separate legal channels. If your will says your IRA goes to your daughter but the beneficiary form names your ex-spouse, your ex-spouse gets the account.

This is one of the most common estate planning mistakes in America, and it causes real heartbreak. We cover this in depth in our article on beneficiary designations, but the bottom line is simple: check your beneficiary forms, and update them whenever your life circumstances change.

What Happens to a 401(k) When You Die

If You Named a Beneficiary

If you have a valid beneficiary on file, the 401(k) passes directly to that person outside of probate. The beneficiary contacts the plan administrator, provides a death certificate, and follows the distribution process.

What happens next depends on who the beneficiary is:

Spousal beneficiaries have the most options:

Roll it into their own IRA — This is the most common choice. Your spouse treats the inherited 401(k) as their own, contributing to it, managing it, and taking distributions based on their own retirement timeline.
Leave it in the plan — Some employer plans allow the surviving spouse to keep the funds in the existing 401(k).
Take distributions over time — Subject to the rules below.
Take a lump sum — Available, but usually not ideal due to the immediate tax hit.

Non-spousal beneficiaries (children, siblings, friends, etc.) have more limited options. Under current rules established by the SECURE Act, most non-spouse beneficiaries must withdraw the entire account within ten years of the account holder's death. There is no more "stretch IRA" option for most non-spouse beneficiaries.

If You Did Not Name a Beneficiary

If you did not designate a beneficiary — or if your named beneficiary died before you and you never updated the form — the account typically follows the plan's default provisions. This often means the funds go to your spouse first, then to your estate. If it goes through your estate, it becomes subject to probate, and the distribution options become much less favorable from a tax perspective.

If You Are Still Working

If you die while still employed by the company sponsoring the 401(k), the rules are the same. The beneficiary designation controls where the money goes.

What Happens to a Traditional IRA When You Die

Traditional IRAs follow similar rules to 401(k)s with some important differences:

Spousal Beneficiaries

A surviving spouse can:

Roll the IRA into their own IRA — The most flexible option
Remain as the beneficiary of the inherited IRA — This can be advantageous if the surviving spouse is under fifty-nine and a half, as inherited IRA distributions are not subject to the early withdrawal penalty
Take a lump sum distribution — All funds are taxable as ordinary income in the year received

Non-Spousal Beneficiaries

Under the ten-year rule, non-spouse beneficiaries must empty the account within ten years. There are exceptions for "eligible designated beneficiaries," which include:

Minor children of the account holder (but not grandchildren) — the ten-year clock starts when they reach the age of majority
Individuals who are disabled or chronically ill
Beneficiaries who are not more than ten years younger than the deceased

These eligible designated beneficiaries can still stretch distributions over their life expectancy.

The Tax Reality

Here is something many people do not realize: distributions from an inherited traditional IRA or 401(k) are taxed as ordinary income. If your beneficiary inherits a large account and must withdraw it all within ten years, the tax impact can be substantial.

For example, if you leave a traditional IRA worth several hundred thousand dollars to your adult child who is in their peak earning years, those withdrawals are added to their existing income. This could push them into a higher tax bracket.

What Happens to a Roth IRA When You Die

Roth IRAs are different in an important way: you already paid taxes on the contributions. That means distributions to your beneficiaries are generally tax-free, as long as the account has been open for at least five years.

Spousal Beneficiaries

A surviving spouse can:

Roll the Roth IRA into their own Roth IRA — Continues tax-free growth with no required distributions during their lifetime
Remain as beneficiary — Start taking distributions, which are tax-free

Non-Spousal Beneficiaries

The ten-year rule still applies — non-spouse beneficiaries must empty the Roth IRA within ten years. However, because Roth distributions are generally tax-free, this is much less painful than it is with traditional IRAs. Beneficiaries can let the money grow tax-free for up to ten years and then withdraw it without any income tax.

If you are trying to maximize what you pass to the next generation, Roth conversions during your lifetime can make inherited accounts significantly more valuable to your heirs.

This is why many financial advisors recommend Roth conversions as part of an estate planning strategy — paying the taxes now so your beneficiaries do not have to.

Pensions and Employer Plans

Pension benefits depend on the plan and the choices you made when you began receiving benefits:

Single life annuity — Payments stop when you die. Nothing passes to your family.
Joint and survivor annuity — Your spouse (or other named beneficiary) continues to receive a percentage of the benefit after your death.
Period certain annuity — If you die during the guaranteed payment period, your beneficiary receives the remaining payments.

If you are still working and have not started pension benefits, the plan may offer a death benefit to your spouse or beneficiary. Check your plan documents.

Common Mistakes That Cost Families

Forgetting to Name a Beneficiary

This is more common than you think, especially with old employer plans. If you rolled over a 401(k) from a previous job into an IRA years ago, did you update the beneficiary? If you opened the account when you were single and are now married, is your spouse listed?

Naming Your Estate as Beneficiary

When your estate is the beneficiary, the retirement account must go through probate and loses most of the tax-advantaged distribution options. The ten-year rule may not even apply — instead, the entire account might need to be distributed within five years or based on the deceased's remaining life expectancy.

Not Updating After Life Changes

Divorce, remarriage, the birth of children, the death of a beneficiary — all of these require you to review and potentially update your beneficiary designations. A divorce decree does not automatically remove your ex-spouse from your 401(k) beneficiary form (though some state laws may override this in certain situations — consult an attorney for your specific situation).

Overlooking Contingent Beneficiaries

Most accounts allow you to name both primary and contingent beneficiaries. If your primary beneficiary dies before you and you have not named a contingent, the account may default to your estate — the exact situation you want to avoid.

What Your Family Needs to Know

When you die, your family needs to move quickly on retirement accounts — but they also need to move carefully. Mistakes in handling inherited retirement accounts can trigger unnecessary taxes and penalties.

Make sure someone in your life knows:

Which retirement accounts you have — Include the institution, account type, and approximate balance
Who the named beneficiaries are — And when you last updated them
Where to find the account information — Login details, statements, or contact information for the plan administrators
Whether you have a financial advisor — They can guide your beneficiaries through the distribution process

This information does not belong locked in a filing cabinet that nobody knows about. It needs to be documented somewhere your family can find it.

Action Steps

Check every beneficiary designation. Log into each retirement account and verify who is listed. Do this today.
Name contingent beneficiaries. Always have a backup in case your primary beneficiary cannot inherit.
Consider the tax implications. Talk to a financial advisor about whether Roth conversions or other strategies could reduce the tax burden on your heirs.
Document everything. Create a record of all your retirement accounts, beneficiaries, and relevant details. Keep it where your family can find it.
Review after every major life change. Marriage, divorce, birth, death — any of these should trigger a beneficiary review.

The Bottom Line

Your retirement accounts may be the most valuable assets you leave behind. How they pass to your family — and how much your family keeps after taxes — depends on decisions you make now. Beneficiary designations are not a "set it and forget it" task. They are a living part of your estate plan that needs regular attention.

And beyond the legal paperwork, your family needs the practical details: which accounts exist, where they are, and who to call. That information is just as important as the beneficiary form itself.
