When it comes to retirement planning, most people focus on securing income for their own golden years. But if you’ve done well financially and your goal is to pass on wealth to your children, there’s another crucial piece to the puzzle—how you leave that money behind can matter just as much as how much you leave.

Enter the Roth conversion.

Unlike traditional IRAs and 401(k)s, which saddle your heirs with future tax bills, Roth IRAs offer a unique opportunity to transfer tax-free income to the next generation—potentially shielding them from high tax brackets, preserving more of your hard-earned savings, and simplifying their financial lives.

In this post, we’ll break down:

• Why Roth conversions can be a smart estate planning move
• The tax and timing strategies that make it work
• Real-life examples of families who benefited from early conversions
• What to watch out for if you’re nearing RMD age or in a high tax bracket

Whether you’re in your 50s, already retired, or just thinking ahead for your family’s future, this guide will show you how strategic Roth conversions can be one of the most effective ways to build a tax-efficient legacy for your children.

✅ 1. Tax-Free Income for Your Children

Example: The Johnsons in Arizona

• Who: Bill (66) and Carol (64), retired schoolteachers in Tucson
• IRA Balance: $900,000 in a Traditional IRA
• Goal: Leave the account to their daughter, Emily, a physician in Boston earning $320K/year

They convert $100,000/year to a Roth for 5 years, paying about 22% in taxes using after-tax savings. When they pass away, the Roth has grown to $750,000.

If left in Traditional IRA: Emily would owe ~35% tax, or ~$262,500, on distributions.
With Roth: She gets the full $750,000 tax-free.

Result: The Johnsons pre-paid taxes at a lower rate, saving their daughter over $250K in future taxes.

⏳ 2. 10 Years of Tax-Free Growth After Death

Example: Samantha Nguyen in Seattle

• Who: Samantha, 70, a retired engineer with no need to spend her $600K Roth IRA
• Child: Her son Josh (35), software developer in Austin, currently earns $200K/year

Samantha passes away at 85. Josh inherits the Roth, and instead of cashing it out immediately, he invests it aggressively for growth.

• At 7% annual return, that $600K grows to $1.18 million in 10 years—tax-free.
• If it had been a Traditional IRA, he would have had to take RMDs and pay taxes each year.

Result: A Roth allows your heirs to delay withdrawals and enjoy a decade of untaxed compound growth.

3. You’re in a Lower Tax Bracket Than Your Kids

Example: The Rodriguezes in California

• Who: Carlos (62) and Maria (60), retired with $80K/year in pensions + Social Security
• IRA Value: $1.3M Traditional IRA
• Children: Two kids in New York and San Francisco, each earning ~$250K/year

Carlos and Maria are in the 22% federal bracket. Their children are in the 35% bracket. Over the next 8 years, they convert $80K/year to a Roth, keeping themselves within the 22% bracket.

Without converting, their kids would owe 35% taxes on inherited IRAs.
With the Roth, the Rodriguezes paid 22% upfront, and the kids get tax-free money.

Result: Paying tax now at 22% avoids heirs paying 35% later—huge intergenerational tax savings.

⚠️ 4. Avoid Big RMDs and Medicare Premiums

Example: George in Florida

• Who: George (71), widower, former contractor, retired in Naples
• IRA Balance: $1 million Traditional IRA
• RMD Starting Next Year: ~$40,000/year

If George does nothing, his RMD will increase his taxable income and push him into a higher Medicare bracket (IRMAA), adding $100+/month in premiums.

Instead, George converts $90K/year to a Roth from ages 71–73. That reduces his Traditional IRA to ~$700K and lowers future RMDs to ~$30K/year.

Result: He keeps income below IRMAA thresholds, pays less in Medicare premiums, and builds a Roth for his two grandchildren.

5. Less Headache for Your Kids

Example: The Millers in Colorado

• Who: Dave (67) and Linda (66), retired small business owners
• Assets: $850K in Traditional IRA, $250K in savings
• Children: One daughter in Washington D.C., a single parent working full-time

Dave and Linda know their daughter is busy and not financially savvy. They don’t want to burden her with tax planning or worrying about how much to withdraw from an inherited Traditional IRA.

So they convert $100K/year to Roth over 7 years while living modestly and using savings to pay taxes. When they pass, their daughter receives a $700K+ Roth IRA, no tax paperwork, and no required withdrawals until year 10.

Result: A Roth IRA makes inheritance simple—no tax slips, no deadlines, just flexibility.

6. Leave a Tax-Free Legacy

Example: The Kumars in New Jersey

• Who: Arvind (65) and Priya (64), first-generation immigrants, both retired engineers
• Children: Two adult sons, both in corporate finance, married with children
• IRA Balance: $1.5 million (all Traditional)

Their goal is to leave as much as possible, tax-free, to support their grandchildren’s college costs and future down payments.

They convert ~$100K/year for 10 years, staying within the 24% bracket. They pay taxes from a taxable brokerage account. By age 75, they’ve converted $1M to Roth, and it continues to grow tax-free.

Result: Their sons will inherit Roth IRAs for each branch of the family—creating a multi-generational tax-free asset.

Potential Pitfalls to Watch Out For

• Triggering Medicare IRMAA surcharges: Roth conversions increase your AGI, which can raise Medicare premiums if you’re over 65.
• Pushing yourself into higher tax brackets: Be careful with conversion amounts.
• Losing ACA subsidies (for early retirees): If you’re under 65 and using the ACA, conversions can reduce or eliminate health insurance subsidies.
• Paying conversion taxes from IRA funds: Ideally, use taxable or cash savings to pay taxes so the full Roth conversion grows tax-free.

Final Thoughts

Roth conversions aren’t just a retirement income tool—they’re a strategic legacy planning move. If your kids are high earners or if you want to preserve your wealth across generations in the most tax-efficient way possible, converting now could pay off later.

The earlier you plan, the more flexibility you have. Whether you’re in your 50s, retired, or managing a family trust, consider how Roth conversions can help you leave a smarter legacy—one your children will thank you for.
