The Roth Conversion Mistake That Could Cost You in Retirement
Jul 13, 2026Should You Make a Roth Conversion? You May Be Asking the Wrong Question
Most people approach Roth conversions with one question: “Should I convert?”
According to retirement planner Leibel Sternbach, that may be the easiest part of the decision. The more important questions are how much to convert, when to do it, how aggressively to proceed, and whose future tax bill you are ultimately trying to reduce.
In a recent podcast episode, Leibel discusses the ideas behind his upcoming book, The 30 Day Roth Conversion Handbook. The book is designed to guide readers through the same decision-making process he uses with clients who are preparing for retirement.
Roth Conversion Advice Cannot Be One-Size-Fits-All
General financial advice often presents Roth conversions as an obvious choice: pay the taxes now, allow the money to grow tax-free, and potentially leave a more tax-efficient inheritance to your family.
However, the right answer is rarely that simple.
Two people can appear nearly identical on paper and still require very different strategies. Their income needs, tax situations, retirement timelines, family priorities, and legacy goals may lead to completely different recommendations.
A Roth conversion increases taxable income in the year it is completed. That could affect cash flow, Medicare premiums, the taxation of Social Security benefits, and other parts of a retirement plan.
Converting too little may leave valuable tax-planning opportunities unused. Converting too much could create an unnecessary tax burden today.
The goal is not simply to complete a Roth conversion. The goal is to determine whether the conversion creates a meaningful long-term benefit.
Early Retirement Decisions Can Have Lasting Consequences
Leibel’s motivation for writing the book is deeply personal. His father died at age 63 without a complete financial plan. Despite having financial knowledge and professional experience, he left behind debt and an outdated beneficiary designation that caused retirement assets to go to the wrong person.
The lesson is important: knowing what to do is not the same as having a properly implemented plan.
The years immediately before and after retirement are filled with decisions that may have lasting consequences. Choices involving taxes, retirement accounts, beneficiaries, income, and estate planning can be difficult or impossible to reverse.
That is why retirement planning should involve more than a series of isolated financial moves. Every decision should be evaluated based on how it affects the rest of the plan.
What Is the Purpose of Your Roth Conversion?
Before deciding how much to convert, it is important to understand why you are considering a conversion.
Are you trying to reduce required minimum distributions later in retirement? Are you concerned that future tax rates may be higher? Do you want to create tax-free income for a surviving spouse? Are you hoping to leave more tax-efficient assets to your children?
Your reason for converting should drive the strategy.
A thoughtful Roth conversion plan considers both your lifetime needs and the financial impact on the people you care about. It should also account for how taxes may change after the death of a spouse, when the survivor may have to file as a single taxpayer using less favorable tax brackets.
A Roth Conversion Is a Process
The strongest Roth conversion strategies are often completed over several years. Each year creates another opportunity to evaluate income, tax brackets, market conditions, cash needs, and changes in tax law.
Instead of asking only, “Should I convert?” ask:
How much can I convert without creating unintended tax consequences?
Which years may offer the best conversion opportunities?
How will the conversion affect my retirement income and cash flow?
Who will ultimately benefit from the strategy?
These questions require more than a general rule of thumb. They require a coordinated retirement and tax strategy based on your circumstances.
Before making a Roth conversion, make sure the decision supports your complete retirement plan. Schedule a consultation with Leibel Sternbach to explore your options at https://www.yields4u.com/pages/book.
