The 5 Roth conversion myths costing IRA millionaires a fortune are objections that sound prudent at any balance but give the wrong answer once a household holds seven figures in pre-tax IRAs and 401(k)s: I do not want to pay the tax, I will lose compounding, the ripple effects are too severe, I will be in a lower bracket later, and Congress will change the rules.
The 5 Roth conversion myths costing IRA millionaires a fortune fail at scale because a large traditional IRA keeps compounding, and required minimum distributions (RMDs) starting at age 73 (age 75 for those born in 1960 or later, first affected in 2035) force taxable income out. Converting does not decide whether tax is paid, only when and at what rate.
Why do the instincts that built a seven-figure IRA start working against you?
Reaching a seven-figure IRA rewards patience, deferral, and letting money compound untouched, but those instincts misfire at IRA-millionaire scale. A larger pre-tax balance means larger future RMDs, which stack on Social Security and pensions and push the household into higher brackets. The habits that built the balance quietly enlarge the tax bill on it.

Every traditional IRA dollar is taxed on the way out; the open questions are the year, the rate, and who files the return. Roth conversion planning answers those on purpose.
Myth #1: “I do not want to pay the taxes”
Myth #1 says I do not want to pay the taxes, but a Roth conversion never decides whether tax is paid on pre-tax dollars, only when and at what rate. Every traditional IRA dollar is taxable on withdrawal, and RMDs at age 73 hand the timing to the IRS. Converting on purpose keeps you, not the government, in control of the rate.
The choice is a known rate now versus an unknown future rate once required minimum distributions begin at age 73. Not wanting to pay is a feeling, not a tax strategy.
Myth #2: “Won’t I give up compounding by paying the tax now?”
Myth #2 says paying the tax now surrenders compounding, but at an equal tax rate on both ends the math is a wash. Paying $90,000 today on a $300,000 conversion or paying tax later on the grown balance leaves the same after-tax dollars. What decides the question sits outside the math: future brackets, survivor status, and heir exposure.
Assume $300,000 in a traditional IRA, a 30% eventual tax rate, and the account doubling over 12 years.
| Approach | Growth | Tax | After-tax result |
|---|---|---|---|
| Leave it, pay tax later | $300,000 grows to $600,000 | 30% of $600,000 = $180,000 | $420,000 |
| Convert now, pay tax now | $90,000 tax paid, $210,000 grows to $420,000 | Paid up front | $420,000 |
The results are identical at equal rates, so the opportunity-cost argument cancels. What tips the decision sits outside the compounding math: future brackets, survivor brackets, and heir exposure under the SECURE Act 10-year rule, as our note on the Roth conversion break-even point shows.
Myth #3: “Won’t the ripple effects this year be devastating?”
Myth #3 says a large conversion triggers devastating current-year ripple effects, and the surcharges are real: IRMAA raises Medicare premiums above $109,000 single or $218,000 joint MAGI, the 3.8% Net Investment Income Tax applies over $200,000 single or $250,000 joint, and more Social Security becomes taxable. These are short-term costs weighed against a lifetime of RMD stacking.
A conversion is ordinary income, so it lifts MAGI. It is not itself net investment income, but the higher MAGI can expose other investment income to the 3.8% Net Investment Income Tax. These ripples are the chosen cost of avoiding a far larger recurring one.
How much do a few years of higher Medicare premiums actually cost vs a lifetime of them?
A few years of higher Medicare premiums during a compressed conversion window usually cost less than a lifetime of premiums after RMDs begin on an unconverted balance. IRMAA uses a two-year lookback, so 2026 income sets 2028 premiums. Standard Part B is $202.90 per month in 2026 before surcharges.
Myth #4: “I’ll be in a lower bracket later, so I’ll just wait”
Myth #4 says I will be in a lower bracket later, so I will just wait, but large IRAs rarely cooperate. RMDs are a rising percentage of a growing account that lands on top of Social Security and pensions. For many IRA millionaires, retirement brackets rise rather than fall, and the survivor eventually faces single-filer rates.
The assumption can hold for modest balances but usually fails for seven-figure ones. At RMD age the IRS forces income out based on a balance often larger than modeled. Deciding how much to convert in the lower-income years before RMDs keeps that income from pushing brackets up.
What is the widow’s trap and how does it change the math?
The widow’s trap is the jump in tax rate when the first spouse dies and the survivor files single. Single brackets and IRMAA thresholds hit at far lower income: in 2026 the 24% bracket ends at $201,775 single versus $403,550 joint, and IRMAA starts at $109,000 single versus $218,000 joint. The same RMD income can carry a materially higher effective rate.
Waiting for a lower bracket can mean leaving the surviving spouse in a much higher one. Completing the conversion sequence while both spouses are alive limits that exposure.
Myth #5: “The government will change the rules on Roths”
Myth #5 says the government will change the rules on Roths, but 15 years of law points the other way. The 2010 window removed income limits, the SECURE Act widened access, and starting in 2026 catch-up contributions for higher earners in workplace plans must be Roth. Congress has expanded, and now sometimes requires, Roth treatment.
Roth conversions generate immediate revenue for foregone future revenue, a trade legislators have repeatedly favored. Betting against 15 years of consistent expansion is a wager most households would not take.
Bonus myths: what your advisor and your software miss
Two more beliefs cost IRA millionaires quietly: my advisor said not to, and my software says otherwise. A general-practice advisor may handle only a handful of conversions a year, while conversion strategy is a narrow specialty. Off-the-shelf software rarely models survivor transitions, exact IRMAA thresholds, or heir exposure under the SECURE Act 10-year rule.
A capable advisor can be excellent at broad planning and still not be the specialist for an irreversible seven-figure decision. A general-practice CPA, or off-the-shelf software, may not model survivor transitions, exact IRMAA thresholds, or heir exposure under the SECURE Act 10-year rule.
What does believing these myths actually cost?
Believing all five myths produces years of delay, and delay has a price. When RMDs eventually force taxable income out of a growing balance, postponed conversions tend to occur in higher-bracket years or fall to a surviving spouse or heirs. The longer the wait, the less room remains to spread income across lower-bracket years.
| The myth | The reality at IRA-millionaire scale |
|---|---|
| #1: “I do not want to pay the taxes” | Tax is paid either way; the choice is when and at what rate |
| #2: “I will give up compounding” | The math is a wash at equal rates; outside variables decide |
| #3: “The ripple effects will be devastating” | Short-term IRMAA and NIIT usually cost less than lifetime RMD stacking |
| #4: “I will be in a lower bracket later” | Large IRAs and the widow’s trap often push brackets up, not down |
| #5: “The government will change the rules” | 15 years of law has expanded Roth access, not restricted it |

Frequently asked questions
Common questions about the 5 Roth conversion myths costing IRA millionaires a fortune center on downside, timing, high earners, and whose advice to trust. The answers below are educational and general. A conversion is irreversible, must be completed by December 31, and cannot convert an RMD, so specifics depend on a household’s full tax picture.
What is the downside of a Roth conversion?
The main downside is a larger tax bill in the conversion year. Converted amounts are ordinary income that can raise your bracket, add IRMAA surcharges above $109,000 single or $218,000 joint MAGI, and pull other investment income into the 3.8% NIIT. It is irreversible and must be completed by the December 31 deadline.
At what age does a Roth conversion not make sense?
There is no single cutoff age, but conversions get harder to justify when the tax-free growth window is short or when IRMAA’s two-year lookback would raise near-term premiums with little offset. Because RMDs begin at age 73 (age 75 for those born in 1960 or later), many households convert most in the lower-income years before RMDs start.
Do Roth conversions make sense for high-income earners?
Yes, high earners can convert. Roth conversions have no income limit, unlike Roth contributions, which phase out at $242,000 to $252,000 MAGI for joint filers in 2026. High earners often hold the largest pre-tax balances and face the biggest future RMDs, so partial conversions that fill a bracket may reduce lifetime tax.
How do I avoid taxes on a Roth conversion?
You cannot avoid tax on a conversion; converted dollars are ordinary income. You can reduce it by converting across multiple years to fill lower brackets rather than in one lump, converting in low-income years before RMDs, and coordinating with Social Security timing. You cannot convert an RMD, so at age 73 the RMD comes out first.
Is it better to do a Roth conversion before or after RMDs start?
Converting before RMDs begin is often more effective. Once RMDs start at age 73, the required distribution must be taken first and cannot be converted, and that income already occupies the lower brackets. The years between retirement and RMD age frequently offer the lowest-bracket window, which is why many households front-load conversions.
Should I trust my regular financial advisor’s advice on Roth conversions?
On broad financial planning, often yes. On conversion strategy for a seven-figure IRA, many general-practice advisors handle only a few conversions a year and may not model survivor brackets, IRMAA thresholds, or heir exposure under the SECURE Act 10-year rule. A second opinion from a specialist can be worthwhile before an irreversible decision.
Plan your Roth conversion strategy today
The way past the 5 Roth conversion myths costing IRA millionaires a fortune is a projection built around your actual numbers across every year of retirement, not a single-year snapshot. A multi-year plan weighs bracket filling, IRMAA, survivor rates, and heir exposure together, and the right sequence depends on your balance, income, and timeline.
