Reaching IRA Millionaire status — a seven-figure balance across traditional IRAs, 401(k)s, and similar pre-tax accounts — puts a household in the top 10% of American savers. Getting there almost always means doing the right things consistently over a long period. The challenge is that once the balance is that large, some of the instincts that got the household there start to work against them. Traditional advice — including some of the most common instincts about Roth conversions — begins producing the wrong answer for IRA Millionaires specifically.
After more than 16 years of focused Roth conversion work and more than 15,000 conversations with households wrestling with these decisions, our team has watched the same five myths keep IRA Millionaires from protecting significant portions of their wealth. Each myth is understandable. Each one is also demonstrably wrong for households at this asset level. This article walks through the five in order, shows the math or the pattern that disproves each one, and covers two bonus myths that show up almost as often.
Myth #1: “I Don’t Want to Pay the Taxes”
The first myth is the most emotionally honest. A household with substantial pre-tax dollars looks at a Roth conversion and sees a large voluntary tax bill they don’t have to write today. Nothing feels rational about writing that check.
The psychology is understandable. The framing is wrong. A Roth conversion is not a question of whether the household pays tax on those dollars. It is a question of when and at what rate. Every dollar in a traditional IRA was contributed on a deal with the IRS — growth is tax-deferred now, taxable later. “Later” is not optional.
Get Past the Myths
Our team has had more than 15,000 conversations with IRA Millionaires wrestling with these same objections — and built more than 2,400 conversion plans for households who moved past them. Find out what your household is actually leaving on the table, with no product pitch and no obligation.
The choice available today is between paying tax at a known rate on the household’s chosen schedule, or paying tax later at whatever rate applies, on the IRS’s schedule via required minimum distributions. A well-designed Roth conversion strategy is what puts the household in control of the timing rather than the government.
Not wanting to pay the tax now is a valid feeling. It is not a valid reason to skip the strategy that determines whether the household pays less tax overall.
Myth #2: “I’ll Give Up Compounding by Paying Taxes Now”
The second myth is the most mathematically sophisticated. The argument goes: paying $90,000 in tax today means $90,000 that isn’t growing in the household’s account. Why pay the tax now when that money could compound for another decade or two before it is finally owed?
The math actually works out to be a wash when the tax rate is the same at both points. Consider a concrete illustration.
Assume $300,000 in a traditional IRA today, an eventual tax rate of 30%, and a doubling of the account over 12 years.
Scenario A: Leave it and pay tax later. $300,000 grows to $600,000. Tax at 30% = $180,000. Net remaining: $420,000.
Scenario B: Convert now and pay tax now. $90,000 tax paid on the $300,000 conversion. $210,000 remaining goes into the Roth. Grows to $420,000 over 12 years. Net remaining: $420,000.
The two scenarios produce identical outcomes when the tax rate is the same. The opportunity-cost argument cancels — the math is a tie. What tips the decision one way or the other is what happens outside the compounding math: what future tax bracket the household actually lands in, what happens to the surviving spouse’s brackets, what happens to heirs’ brackets under the SECURE Act 10-year rule, and how much of the balance gets forced out by RMDs regardless of what the household wants.
The compounding argument doesn’t lose the debate. It just doesn’t win it either. Those other factors decide it.
Myth #3: “The Ripple Effects on This Year Will Be Devastating”
The third myth focuses on the current-year damage a large conversion creates. IRMAA Medicare surcharges. The 3.8% Net Investment Income Tax add-on. Higher taxation of Social Security. Potentially a jump into a higher federal bracket. Each of these is real, and each one shows up on the return in the conversion year.
The problem is scope. Tax planning done well is not a single-year exercise. When the lens opens up to the household’s entire retirement, most of those ripple effects turn out to be short-term costs that produce much larger long-term benefits.
A few years of higher Medicare premiums during a compressed conversion sequence typically costs less over a lifetime than a decade of higher Medicare premiums after RMDs begin on an unconverted balance. A few years of Social Security taxed at 85% during conversion years typically costs less than a lifetime of Social Security taxed at 85% because RMDs are stacking on top of it. The current-year ripple effects are the household’s chosen cost of buying out of a much larger future cost. For more on the Medicare piece specifically, see our team’s analysis of how Roth IRA conversions impact Medicare premiums.
Myth #4: “I’ll Be in a Lower Bracket Later — I’ll Just Wait”
The fourth myth is the most confidently stated. Many households assume that when work income stops and Social Security starts, their tax bracket will drop. That assumption may be roughly correct for households with modest IRA balances. For IRA Millionaires, it usually isn’t.
Here’s why. A large traditional IRA continues to compound. Federal pension income, Social Security, and other retirement income sources stack. At RMD age, the IRS forces taxable income out based on the balance at that point — and that balance is likely much larger than the household modeled. The RMDs land on top of the other income and push the household into higher brackets, not lower ones.
Then there is the widow’s trap. When the first spouse passes, the surviving spouse inherits the same IRA balance but now files as a single taxpayer. Single-filer brackets and IRMAA thresholds hit at much lower income levels than joint thresholds. The same forced RMD income that felt manageable at joint rates can produce a 20%, 30%, or even 40% higher effective tax rate on the surviving spouse. “I’ll wait for a lower bracket” often means “I’ll leave my spouse in a much higher one.”

Myth #5: “The Government Will Change the Rules on Roths”
The fifth myth is the political-uncertainty argument. Households worry that after they pay tax on a conversion, Congress will change the rules — retroactively tax Roth balances, cap Roth withdrawals, or otherwise take away the benefit.
The worry is emotionally reasonable. The historical evidence points the other way. Since Roth IRAs were introduced, Congress has consistently expanded access to them, not restricted it. The 2010 conversion window, which lifted income limits on conversions and gave taxpayers two years to spread the resulting tax bill, generated meaningful Treasury revenue and demonstrated that Roth expansion is a revenue-positive policy. The SECURE Act opened Roth access further. Starting in 2026, catch-up contributions in 401(k) plans for higher earners must route to Roth accounts — for the first time, Congress is requiring Roth treatment in some cases.
Roth IRAs generate immediate revenue for Treasury (the conversion tax) in exchange for foregone future tax revenue. That trade-off has proven to be an attractive one for legislators. Betting against it — and against 15 years of consistent legislative direction — is a wager most households wouldn’t take on any other financial question.
Bonus Myths: What Your Advisor and Software Miss
Two additional patterns show up almost as often as the five myths above. They deserve their own recognition.
“My advisor said not to.” Most general-practice financial advisors are excellent at what they’re trained to do — managing investments, selecting products, coordinating financial plans across broad household needs. Roth conversion optimization is a specialized subset of that work, and most advisors handle a small number of conversions per year rather than thousands. The advisor isn’t wrong about the household’s broader financial picture. They are just not the specialist for this specific decision — the same way a family doctor isn’t the surgeon for a specialized procedure.
“My software says otherwise.” A wide range of Roth conversion software is available to households and advisors. Most of it is built for the broad population — households with modest balances, straightforward income situations, and predictable RMDs. IRA Millionaire scenarios include variables that off-the-shelf software often doesn’t model well: survivor bracket transitions, precise IRMAA threshold interactions, heir tax exposure under the SECURE Act 10-year rule, and multi-decade projections that account for tax-law uncertainty. Software is a useful tool. It is not a substitute for a plan built around a household’s actual numbers.
What Believing These Myths Actually Costs
Each myth in isolation feels like a reasonable pause. Believing them collectively — waiting because the psychology is uncomfortable, then waiting because the compounding math seems compelling, then waiting because the ripple effects are unpleasant, then waiting because a lower bracket seems likely, then waiting because Congress might change the rules — produces years of delay. Every year of delay carries a specific cost.
[VISUAL 4: Table — the 5 myths at a glance, below]
| Myth | The Honest Response |
|---|---|
| #1: “I don’t want to pay the taxes” | You’ll pay them anyway — the choice is when and at what rate |
| #2: “I’ll give up compounding” | The math is a wash at equal rates; outside variables decide |
| #3: “The ripple effects will be devastating” | Short-term ripple effects almost always cost less than the lifetime alternative |
| #4: “I’ll be in a lower bracket later” | Large IRAs and the widow’s trap usually push households into higher brackets |
| #5: “The government will change the rules” | 15 years of legislation has consistently expanded Roth access, not restricted it |
Our team’s research across more than 2,000 real client conversion plans shows that a single year of waiting on a well-built strategy typically costs approximately $66,000 in projected lifetime tax savings. Five years of waiting typically costs approximately $357,000. Those numbers scale with balance size — larger IRA Millionaire households face substantially larger costs.
The myths don’t feel expensive in the moment. They compound quietly in the background, exactly like the pre-tax dollars they were meant to protect. By the time RMDs begin and the math becomes concrete, most of the optionality is gone.

Frequently Asked Questions
Is it true that I’ll be in a lower tax bracket in retirement?
For households with modest IRA balances, often yes. For IRA Millionaires, usually not. A large traditional IRA continues to compound, RMDs are calculated as a percentage of that growing balance, and RMD income lands on top of Social Security and other retirement income. The combination typically pushes IRA Millionaire households into higher brackets in retirement, not lower.
Isn’t there an opportunity cost to paying conversion taxes now?
At the same tax rate on both ends, the math is a wash — the amount the household ends up with is identical whether it converts now or later. What tips the decision is what happens outside the pure compounding math: future tax brackets, survivor brackets, IRMAA thresholds, and heir tax exposure. Those are the variables that decide the conversion question, not the compounding argument.
Will Congress take away the Roth tax-free benefit?
Historical evidence points the other way. Since Roth IRAs were introduced, Congress has consistently expanded access, not restricted it. Roth conversions generate immediate Treasury revenue, which has proven to be an attractive policy trade-off across multiple administrations and legislative sessions.
What is the widow’s trap and how does it affect Roth conversion decisions?
When a married household leaves a large traditional IRA, the surviving spouse inherits the same balance but files as a single taxpayer. Single-filer brackets and IRMAA thresholds hit at much lower income levels than joint thresholds. The same forced RMD income that was manageable at joint rates can produce a 20% to 40% higher effective tax rate on the surviving spouse. Completing the conversion sequence while both spouses are alive substantially reduces that exposure.
Should I trust my regular financial advisor’s advice on Roth conversions?
On broad financial planning, usually yes. On Roth conversion optimization for IRA Millionaire households specifically, most general-practice advisors don’t have the specialization to answer the question well. A capable advisor can execute the mechanics; the strategic decision typically requires a specialist who handles conversions as their primary work.
Why isn’t standard Roth conversion software enough for my situation?
Most off-the-shelf Roth conversion software is built for the broad population — modest balances, straightforward income, predictable RMDs. IRA Millionaire scenarios include variables that standard tools often don’t model precisely: survivor bracket transitions, exact IRMAA threshold interactions, heir tax exposure under the SECURE Act 10-year rule, and multi-decade tax-law uncertainty. Software is useful. It is not a substitute for a plan built around actual household numbers.
