When Patricia converted $500,000 from her traditional IRA to a Roth IRA at age 62, she wrote a check for $150,000 in taxes. It was painful. But Patricia wasn't doing it just for herself.
Her three children, ages 32 to 38, were all in their peak earning years with decades of compounding ahead. By paying taxes now at her lower rate, she gave them something more valuable than a large inheritance. She gave them a tax-free inheritance. Over their lifetimes, her decision could save her family more than $400,000 in taxes.
Most people focus on Roth conversions for their own retirement. But the real power often lies in generational wealth transfer. When your heirs inherit a Roth IRA, they receive it completely tax-free. Strategic conversions today create tax-free wealth for decades.
Why Roth Conversions Are Powerful Legacy Tools
Traditional IRAs create a significant problem for your heirs. They don't just inherit your assets. They inherit your tax burden along with them.
Every dollar your children withdraw from an inherited traditional IRA gets taxed as ordinary income at their tax rate, often higher than yours. These forced distributions can push them into higher tax brackets. Your heirs' actual inheritance gets reduced by 25% to 40% or more.
Roth IRAs work completely differently. Your heirs receive distributions entirely tax-free. You have no required minimum distributions during your lifetime. After they inherit, your heirs have a 10-year distribution period with flexibility. Tax-free growth continues during those 10 years. Dramatically more wealth stays in your family.
Consider the math: Your child inherits a $500,000 traditional IRA. If they're in the 32% tax bracket, they'll pay $160,000 in taxes, netting $340,000. That same $500,000 in a Roth? They net the full $500,000, completely tax-free. Plus, the Roth can continue growing tax-free for up to 10 more years.
How Inherited Roth IRAs Work
The SECURE Act of 2020 changed everything. The old rule allowed non-spouse beneficiaries to stretch inherited IRA distributions over their lifetime. The new rule requires most beneficiaries to empty inherited IRAs within 10 years.
Your heirs must withdraw all funds within 10 years, but they have complete flexibility about how much to take in any given year. There are no required annual distributions during those 10 years. The entire balance just needs to be withdrawn by the end of year 10.
The critical difference: every dollar from a traditional IRA gets taxed at your heir's ordinary income rate, potentially 35% or higher. Every dollar from a Roth IRA comes out completely tax-free, including all growth during those 10 years.
Surviving spouses get special treatment. A spouse who inherits your Roth IRA can treat it as their own, face no required minimum distributions, continue tax-free growth indefinitely, and name their own beneficiaries. This is the most powerful option for long-term legacy planning.
Strategic Timing for Conversions
Early Retirement: Before Age 72
This window offers ideal conversion opportunities. You've stopped working, your income has dropped. You haven't started required minimum distributions. You're not yet collecting Social Security.
The strategy: convert your traditional IRA to Roth in chunks over multiple years. Fill up lower tax brackets. Pay conversion taxes from non-retirement accounts. Let the Roth grow tax-free for a decade or more.
Low-Income Years: Business Sale or Career Transition
These temporary windows can be golden opportunities. Perhaps you've sold your business and are planning your next venture. You're between roles. Any year where your income is temporarily lower creates conversion opportunities.
During these years, you may be able to convert six-figure amounts at low tax rates. If you expect income to return to higher levels, the conversion locks in today's low rates.
Market Downturns: Converting When Values Are Depressed
Market downturns create unique opportunities. When your IRA value drops 20% or more, you can convert the same number of shares at lower tax cost. All future recovery happens inside the Roth and grows tax-free forever.
When You Have High-Earning Adult Children
If your adult children are in their peak earning years in the 32% to 37% federal brackets, they'll stay in those high brackets for decades. If they inherit a traditional IRA, every dollar gets taxed at those high rates.
But if you convert while you're in a lower bracket, perhaps 22% to 24% in retirement, you create family tax arbitrage. You pay taxes at your lower rate. Your children receive the inheritance tax-free. The net family savings can be 10% to 15% of total inheritance value.
The Complete Legacy Strategy
Step 1: Ensure Your Own Security First
You cannot prioritize legacy over your own financial security. Before any Roth conversion, ensure you can live comfortably on non-IRA income sources. Can you cover expenses with Social Security, pension, and other savings? Do you have adequate funds to pay conversion taxes? Will you potentially need IRA funds for long-term care?
Step 2: Analyze Your Heirs' Tax Situations
What tax brackets are your heirs in currently? What's their career trajectory? Do they live in high-income-tax states? What will their likely tax situation be when they inherit in 10 to 20 years?
The calculation: your conversion tax rate compared to their future distribution tax rate. If you're in the 22% bracket and your children will be in the 35% bracket, converting makes strong mathematical sense. You pay $22,000 to convert $100,000. They would pay $35,000. You just saved your family $13,000 per $100,000 converted.
Step 3: Decide on Multi-Year Schedule
Gradual conversions over multiple years usually work better. You avoid pushing yourself into high brackets. You spread tax payments over time. You maintain flexibility to adjust.
A conservative approach converts $50,000 to $75,000 annually, staying within lower brackets over eight to 10 years. A moderate approach converts $75,000 to $150,000 annually over five to seven years. An aggressive approach converts $150,000 to $300,000 or more annually over three to five years.
Advanced Legacy Strategies
Roth as Last Asset Spent
This approach maximizes legacy value. Spend taxable accounts and traditional IRA first during retirement. Let your Roth continue growing with no required distributions. Maximize time for tax-free compounding. Your Roth becomes your primary legacy asset.
Naming Trust as Roth Beneficiary
In some situations, naming a trust as your Roth beneficiary makes sense. Consider this if heirs have creditor issues, divorces, or spendthrift concerns. You want to control distribution timing. You have blended family situations. You have minor children.
The trust becomes the beneficiary and dictates distribution terms. This provides asset protection and control. The 10-year rule still applies, but the trust provides protection and structure.
Spousal Inherited Roth for Maximum Legacy
This strategy creates multi-generational tax-free growth. Your spouse inherits your Roth and treats it as their own. They face no required distributions. The Roth continues growing tax-free for potentially decades. Eventually your spouse leaves it to children or grandchildren.
Frequently Asked Questions
Will my heirs have to take required minimum distributions?
No. Roth IRAs have no RMDs during your lifetime, and heirs won't have RMDs during their 10-year distribution period either. They have complete flexibility about when to take distributions, and all distributions are tax-free. This gives maximum flexibility and tax efficiency.
Should I convert even if I'm already taking Social Security?
Possibly yes. The conversion will increase taxable income, which could cause more Social Security to be taxed and might trigger higher Medicare premiums. However, the long-term legacy benefit often outweighs short-term costs. Model this carefully with your advisor. Sometimes smaller annual conversions work better.
Can I name a trust as beneficiary for asset protection?
Yes, and this can be smart for heirs with creditor problems, divorces, or special needs. The 10-year rule still applies, but the trust provides control and protection. Work with an attorney experienced in IRA trusts. The fact that Roth distributions are tax-free makes trust planning simpler than with traditional IRAs.
What if market values drop after I convert?
You cannot undo a Roth conversion. The IRS eliminated recharacterization in 2018. Once you convert, it's permanent. However, remember you're planning for a multi-decade time horizon. Short-term fluctuations matter much less than long-term tax-free growth. If values drop, they'll likely recover and grow tax-free over the years before heirs inherit.
How do I know if converting for legacy makes sense?
Compare your current tax rate to heirs' expected future rate. If you're in the 22% bracket and children will be in 32% to 35% brackets, conversion creates significant family tax savings. Also consider whether you need the IRA for your own retirement. If you can live on other income and the IRA is essentially inheritance, legacy-focused conversions make even more sense.
