Roth Conversion for Legacy Planning: What Happens to Your IRA When Your Kids Inherit It?

Maybe you’ve reached a point where you’ve realized something:

You’re probably not going to spend all of your retirement money.

You have $750,000 in an IRA.

Maybe $1 million.

Maybe $2 million.

Your Social Security, pension, savings, or other income covers much of what you need.

So you start thinking less about yourself and more about your children.

Then a new question shows up:

“What actually happens to this IRA when my kids inherit it?”

That’s when Roth conversion planning can become about much more than your own retirement taxes.

It can become a legacy question.

Quick Answer: Can a Roth Conversion Be Used for Legacy Planning?

Potentially.

A Roth conversion can change the tax character of retirement assets that may eventually pass to your beneficiaries.

Traditional IRA distributions are generally taxable to beneficiaries to the extent the distributions represent taxable retirement money.

Qualified distributions from an inherited Roth IRA are generally tax-free, although inherited Roth accounts are still subject to beneficiary distribution rules.

So if you expect your children to inherit a substantial portion of your retirement assets, comparing a traditional IRA legacy with a Roth IRA legacy may be worthwhile.

But there’s an important tradeoff:

You generally have to recognize taxable income when you convert previously untaxed traditional IRA money to Roth.

In other words, you may be considering paying taxes during your lifetime to potentially change the tax treatment of what your family receives later.

That trade needs to prove itself.

What Happens When Your Kids Inherit a Traditional IRA?

Your IRA doesn’t simply become ordinary cash when you die.

Beneficiary rules apply.

For deaths occurring under current law, many adult children who inherit an IRA as non-spouse designated beneficiaries are subject to a 10-year distribution rule.

In general, that means the inherited account must be completely distributed by the end of the 10th year following the year of the original owner’s death.

There are exceptions and additional rules for certain beneficiaries, so the exact distribution schedule needs to be evaluated based on the beneficiary and the circumstances.

But for many adult children, the old idea of stretching an inherited IRA across an entire lifetime isn’t available.

Do Your Kids Pay Income Tax on an Inherited Traditional IRA?

Taxable distributions from an inherited traditional IRA are generally included in the beneficiary’s gross income.

Think about what that could mean.

Your son is 52 when he inherits your IRA.

He’s an executive earning $225,000 a year.

His wife works too.

They’re already in some of their highest earning years.

Then he inherits a large traditional IRA that has to be distributed according to inherited-account rules.

That’s a very different situation from inheriting ordinary cash.

And it’s why I want to know not only:

“How much are you leaving your children?”

but also:

“What exactly are you leaving them?”

A $1 Million IRA Isn’t Necessarily a $1 Million Inheritance They Can Spend

Suppose your children eventually inherit a traditional IRA worth $1 million.

The statement says $1 million.

But taxable distributions from that account may create income-tax obligations for the beneficiaries.

So the account value and the amount they ultimately have available to spend aren’t necessarily the same number.

This is the same distinction that matters during your retirement.

Account balance isn’t the same thing as after-tax value.

That matters to you.

And it may matter to your children too.

What Happens If Your Kids Inherit a Roth IRA?

Here’s where people sometimes get confused.

A Roth IRA doesn’t mean your children can simply leave the account untouched forever.

Inherited Roth IRAs are subject to beneficiary distribution rules too.

Many non-spouse designated beneficiaries are subject to a 10-year rule.

The major difference is taxation.

Qualified Roth IRA distributions are generally tax-free.

For inherited Roth IRAs, most withdrawals are generally tax-free, although earnings can be taxable in certain circumstances if the applicable Roth five-year requirement hasn’t been satisfied.

So your child may still need to empty an inherited Roth account within the required period.

But the income-tax character of those distributions can look very different from distributions from a traditional IRA.

Traditional IRA vs. Roth IRA Inheritance: What’s the Main Difference?

At a high level:

Traditional IRA: taxable distributions are generally included in the beneficiary’s gross income.

Roth IRA: qualified distributions are generally tax-free, while beneficiary distribution rules still apply.

That sounds like an easy win for Roth.

It isn’t that simple.

Why?

Because somebody generally paid the tax to get the money from traditional to Roth.

And if that somebody is you, the question becomes:

“Is paying the conversion tax during my lifetime worth what it potentially changes for me and my family later?”

Don’t Pay a Huge Tax Bill Just to Leave Your Kids a Roth IRA

This is important.

Your children aren’t the first priority of your retirement plan.

You are.

You need income.

You need liquidity.

You need flexibility.

You need enough money if you live much longer than expected.

You may have healthcare or long-term-care expenses.

So I would never start with:

“How can we convert as much as possible for the kids?”

I would start with:

“What gives you the strongest retirement outcome?”

Then, if you’re projected to leave substantial assets behind, we examine the legacy.

When Does an IRA Become a Legacy Asset?

There’s no official line.

But psychologically, you’ll know when the conversation changes.

You look at your retirement projections and realize:

“We’re probably not going to spend all of this.”

Maybe you have $1.5 million in tax-deferred retirement accounts.

Your home is paid off.

Your Social Security covers a meaningful part of your monthly expenses.

You have other savings.

You don’t live extravagantly.

At that point, some of the IRA may be doing two jobs:

Supporting your retirement.

And potentially becoming an inheritance.

That’s when beneficiary tax treatment deserves more attention.

Your Kids May Inherit the IRA During Their Highest-Earning Years

This is one of the biggest legacy issues people miss.

Imagine you’re 65.

Your daughter is 38.

You live another 25 years.

She’s 63 when she inherits the account.

Maybe she’s still working.

Maybe she and her spouse are both earning substantial incomes.

Maybe she’s already dealing with her own retirement-account distributions.

Then she inherits yours.

You don’t know what future tax laws will be.

You don’t know exactly what she’ll be earning.

But you can recognize the possibility that inherited taxable retirement distributions may arrive during an already complicated financial period.

The 10-Year Rule Can Compress the Decision

For many non-spouse designated beneficiaries, current rules require the inherited IRA to be fully distributed by the end of the 10th year following the year of death.

The exact annual distribution requirements can vary based on the circumstances.

That’s an important distinction.

The rule shouldn’t be interpreted as:

“Everyone can leave the entire account untouched for nine years and take it all in year ten.”

Some beneficiaries may have annual distribution requirements during the 10-year period.

So beneficiary planning needs to consider both the deadline and the applicable annual distribution rules.

What If You Leave $500,000 in a Traditional IRA?

Imagine you expect roughly $500,000 of your traditional IRA to remain when your children inherit it.

What happens?

We could model the traditional path.

How might the account grow?

What distributions might you take?

What might remain?

Then we can consider the beneficiary side.

How many children inherit?

How is the account divided?

What might their financial circumstances look like?

What tax assumptions are being used?

Now we have something meaningful to compare against a Roth conversion strategy.

What If You Leave $1 Million or More?

The larger the potential inherited account, the more meaningful the tax-character question can become.

Imagine two families.

Both leave $1 million of retirement assets to their children.

One inheritance is primarily traditional IRA money.

The other contains a substantial Roth IRA component.

The headline account values might look similar.

The beneficiary tax experience may not.

But again, the Roth didn’t appear magically.

The parents may have paid substantial conversion taxes earlier.

So the analysis has to go all the way back to the parents’ conversion years.

Who Should Pay the Tax: You or Your Children?

That’s one way to frame the question.

Suppose you’re considering converting part of your traditional IRA.

You could pay income tax associated with the conversion now.

Or you could leave the money traditional and allow future taxable distributions to occur under the rules applying to you and eventually your beneficiaries.

Which is better?

Don’t answer that emotionally.

Compare it.

Your tax situation matters.

The projected conversion cost matters.

Your children’s potential tax situations matter.

The amount you actually leave behind matters.

Investment assumptions matter.

Time matters.

What If You Have Multiple Children?

Now the planning gets even more interesting.

Maybe one child is a surgeon earning $400,000.

Another is a teacher earning $70,000.

Another owns a business with highly variable income.

An inherited traditional IRA may interact differently with each beneficiary’s tax situation.

That’s why generic legacy advice can be misleading.

Your family isn’t a spreadsheet full of identical people.

They’re real people with different incomes, ages, careers and financial lives.

What If Your Spouse Inherits First?

This is another major distinction.

A surviving spouse has different options from a typical non-spouse beneficiary.

Depending on the situation, a surviving spouse may be able to treat an inherited IRA as their own, roll eligible assets into their own IRA, or remain a beneficiary.

So your legacy plan may really have two stages:

Stage 1: What happens when the first spouse dies?

Stage 2: What happens when the surviving spouse eventually dies and the children inherit?

Both stages deserve attention.

The Surviving Spouse May Matter More Than the Children

It’s easy to jump straight to:

“What do the kids get?”

But your spouse comes first.

Imagine you’re the one who handles all the finances.

You die first.

Your spouse is suddenly dealing with retirement accounts, beneficiary paperwork, taxes, RMDs, Medicare and investment decisions.

They may also eventually be filing taxes as a single taxpayer.

That’s why I want to know:

“Does this strategy make life better or harder for the person I leave behind?”

“I Don’t Want My Kids to Have to Figure This Out”

This is where legacy planning becomes emotional.

You aren’t only trying to leave money.

You’re trying to avoid leaving a problem.

You may be thinking:

“I don’t want to ask my kids for help.”

Or:

“We should be able to handle this ourselves.”

And underneath both:

“What if we mess this up and regret it?”

Maybe your deeper fear isn’t that your children receive too little.

It’s that they inherit a pile of financial decisions because you never dealt with them.

You worked too hard to build this money to leave behind confusion.

But Don’t Turn Your Retirement Into a Sacrifice for Your Children

There’s another side to that emotion.

Parents sometimes become so focused on leaving money that they start treating their own retirement as secondary.

Don’t.

Your children may want you to use the money.

Travel.

Enjoy retirement.

Handle healthcare.

Stay independent.

Give yourself choices.

A good legacy strategy shouldn’t require you to become financially fragile so your children can inherit more.

Could a Roth Conversion Make the Inheritance Simpler?

Potentially.

If Roth distributions to your beneficiaries are qualified, the income-tax treatment can be simpler than taxable traditional IRA distributions.

But inherited Roth accounts still have distribution rules.

Your children still need to understand beneficiary deadlines.

They still need to manage the account correctly.

So Roth doesn’t eliminate every administrative issue.

It changes the tax characteristics of the asset.

What About the Roth Five-Year Rule?

This deserves attention in legacy planning.

Roth IRA distributions have rules determining whether distributions are qualified.

For inherited Roth IRAs, most distributions are generally tax-free, but earnings can potentially be taxable if the applicable five-year requirement hasn’t been met.

That’s one reason you shouldn’t treat the word “Roth” as if it automatically answers every tax question.

The age of the Roth account and the circumstances matter.

What If You Never Convert Anything?

That’s one of the scenarios we should test.

Leave the traditional IRA alone.

Take your retirement withdrawals.

Take RMDs when applicable.

Let the remaining traditional IRA pass to your beneficiaries.

What happens?

Maybe that strategy works extremely well.

Maybe the conversion tax you would have paid during your lifetime isn’t justified by the projected legacy benefit.

If so, I want the math to show that.

What If You Convert Only the Money You’re Unlikely to Spend?

Now we’re asking a different question.

Instead of converting the entire IRA, maybe you identify the portion of the account that projections suggest is more likely to become legacy money.

Then you model partial conversions.

Not because that portion automatically should be converted.

Because now you can compare:

Leave potential legacy assets traditional.

versus:

Recognize conversion taxes during your lifetime and potentially leave Roth assets.

That’s a much more precise question.

Legacy Planning Is Really an After-Tax Question

People love talking about how much they’re leaving behind.

“The kids will get $1 million.”

Maybe.

But I want to know what kind of $1 million.

Cash?

Brokerage assets?

Traditional IRA?

Roth IRA?

Life insurance?

Real estate?

Those assets can have very different tax and distribution characteristics.

The size of the inheritance matters. The structure of the inheritance matters too.

Don’t Make the Roth Decision Based Only on Your Kids’ Tax Rates

You don’t know exactly what your children’s tax rates will be years from now.

You don’t know exactly what tax law will look like.

You don’t know precisely when you’ll die.

You don’t know exactly how large the account will be.

So don’t build the entire strategy around one future tax-rate prediction.

Instead, test different assumptions.

What happens if future tax rates are higher?

Lower?

Similar?

What happens if you live longer?

What happens if you spend more of the IRA?

What happens if the children inherit less?

A strategy should survive more than one perfect forecast.

The Retirement Math Method™

This is exactly why I use the Retirement Math Method™.

I don’t start by telling you:

“Convert your IRA so your kids get tax-free money.”

That’s far too simplistic.

We start with you.

Your retirement income.

Your existing assets.

Your tax-deferred accounts.

Your projected withdrawals.

Your RMDs.

Your spouse.

Your legacy goals.

Then we model potential Roth conversion scenarios.

Different amounts.

Different years.

Different assumptions.

And we compare those against leaving the IRA traditional.

Then you can see what each path is projected to produce for you and potentially for the people who inherit what’s left.

I don’t try to sell you on the strategy. I make the strategy prove itself with the math.

Frequently Asked Questions About Roth Conversions and Legacy Planning

What happens when my children inherit my traditional IRA?

Many adult children who inherit a traditional IRA as non-spouse designated beneficiaries must empty the inherited account by the end of the 10th year following the owner’s death. Taxable distributions from an inherited traditional IRA are generally included in the beneficiary’s gross income. Special rules and exceptions apply to certain beneficiaries.

Do my children pay taxes when they inherit a Roth IRA?

Inherited Roth IRAs remain subject to beneficiary distribution rules, but qualified Roth distributions are generally tax-free. Earnings can be taxable in certain circumstances when the applicable Roth five-year requirement hasn’t been satisfied.

Do inherited Roth IRAs have a 10-year rule?

Many non-spouse designated beneficiaries are subject to a 10-year distribution rule for inherited Roth IRAs. Special rules and exceptions apply to eligible designated beneficiaries such as certain disabled or chronically ill individuals and other qualifying beneficiaries.

Do my children have to take annual distributions from an inherited IRA?

The distribution schedule can vary based on the type of account, when the original owner died, whether the original owner had reached the required beginning date, and the beneficiary’s status. Some beneficiaries subject to the 10-year rule may also have annual distribution requirements. The applicable inherited-account rules should be reviewed for the specific beneficiary.

Can my children stretch an inherited IRA over their entire lives?

Many adult children who are non-spouse designated beneficiaries can no longer use a lifetime stretch under current rules. They are generally subject to the 10-year rule. Certain eligible designated beneficiaries receive different treatment.

Should I convert my traditional IRA to Roth for my children?

Not solely because your children may prefer inheriting Roth assets. A conversion can create substantial taxes during your lifetime. Your retirement security, conversion cost, expected spending, spouse, beneficiaries and projected legacy outcomes all belong in the comparison.

Is an inherited Roth IRA completely free from distribution rules?

No. Roth IRA owners currently have no lifetime RMDs from their own Roth IRAs, but beneficiaries of inherited Roth IRAs are subject to inherited-account distribution rules.

What happens if my spouse inherits my IRA first?

A surviving spouse has options that aren’t generally available to a non-spouse beneficiary. Depending on the circumstances, the spouse may be able to treat the IRA as their own, complete an eligible rollover, or remain a beneficiary. The appropriate choice should be evaluated based on the surviving spouse’s circumstances.

Is Roth conversion planning the same as estate planning?

No. Roth conversion analysis can be one part of broader legacy planning, but it doesn’t replace estate planning. Wills, trusts, beneficiary designations, powers of attorney and other estate-planning issues should be addressed with qualified legal and tax professionals when appropriate.

You’re Not Just Leaving an Amount. You’re Leaving a Financial Asset With Rules Attached.

That’s the part I want people to understand.

You may say:

“I want to leave each of my kids $500,000.”

That’s a great goal.

Now let’s go one step further.

What form will that $500,000 take?

What rules come with it?

What taxes could come with it?

When will they have to take it?

And what did it cost you during your lifetime to create that inheritance?

Those are better questions.

You spent decades building the money. If part of it is going to outlive you, make sure you understand what you’re actually leaving behind.

Want to Compare What Your Kids Could Inherit Under Different Retirement Strategies?

If you’re roughly 55 to 65, have $500,000 or more in tax-deferred retirement accounts, and believe you may leave a meaningful portion of those assets to your spouse or children, this is exactly the kind of comparison I help people analyze.

You don’t need to decide ahead of time that you’re doing a Roth conversion.

We can start with what happens if you leave the IRA exactly as it is.

Then we can compare potential conversion scenarios and examine what each path is projected to mean for your retirement, your spouse, and the assets eventually left to your beneficiaries.

You see the assumptions.

You see the projected numbers.

Then you decide.

No pressure to make a decision on the spot. We run the math first.
