Key Points
It's common for higher earners to near retirement without any money in a Roth IRA.
Doing conversions in your pre-retirement years could be a smart bet.
Just be mindful of other implications, like taxes on Social Security and Medicare surcharges.

There's a reason higher earners tend to reach the end of their careers with little to no money in a Roth IRA. Higher earners are often barred from funding Roth IRAs directly. And for those whose incomes are just below the limit, a traditional IRA might still seem more appealing due to the tax break on contributions.
If you're a higher earner who's getting close to retirement, you might assume that your opportunity to fund a Roth IRA has passed. But there's a move you may be able to make in the coming years that allows you to enjoy the benefits of having a Roth IRA in retirement.

Take advantage of lower-income years
Even if you were a higher earner for much of your career, you may enter a period of life when your income drops. There's often a window between leaving a job and when required minimum distributions (RMDs) apply to your traditional retirement savings plans.
During that time, you may be working part-time or not at all. You may be mostly living on Social Security with supplemental withdrawals from your retirement savings.
Either way, if your income is lower for a few years, that gives you an opportunity to do a Roth conversion. If you have a large retirement plan balance, you may be unable to get all of it into a Roth before RMDs become mandatory.
But if you can convert at least some of your savings to a Roth IRA, you can benefit from tax-free withdrawals. You'll also shield some of your nest egg from RMDs.
Time your Roth conversion carefully
You may have a limited window to move some of your savings into a Roth IRA. So, it's important to proceed carefully and remember that it may be unfeasible to move your savings into a Roth entirely.
Remember, Roth conversions count as income. They could not only drive up your taxes but also have other implications.
For one thing, they could push you over the threshold where your Social Security benefits become taxable. But to be fair, if you're living on those benefits plus retirement plan withdrawals or part-time earnings, you may already be at that point.
The bigger issue may be Medicare surcharges. If you get stuck with IRMAAs, or income-related monthly adjustment amounts, you could end up paying more for Medicare Part B as well as Part D.
For this reason, it's a good idea to work with a tax or financial professional on Roth conversions. But don't assume you're stuck without a Roth IRA for retirement because you missed the chance to contribute to one of these accounts while you were working. There may still be a limited but feasible window to get some of your money into a Roth IRA and enjoy the perks that come with it.

Four leading AI models discuss this article
"Roth conversions are tactically sound but the article underweights the IRMA penalty trap and ignores that conversion timing is a bet on future tax policy, not a guaranteed win."
This article conflates tax planning advice with investment opportunity, which is a category error. Roth conversions are legitimate tax-optimization tactics for high earners in low-income years—the mechanics are sound. But the piece treats this as *news* when it's evergreen financial planning. The real tension: conversion timing is exquisitely sensitive to future tax rates, Medicare thresholds, and Social Security taxation rules—all of which are politically volatile. A retiree converting $500k in 2024 at 24% federal rates faces unknown risk if rates rise post-2025. The article mentions IRMAAs (income-related Medicare surcharges) in passing but undersells how a single conversion year can trigger 3-5 years of higher Medicare premiums, potentially erasing tax savings. Missing: state income taxes, which vary wildly and aren't discussed.
If tax rates rise significantly post-2025 (likely given deficit dynamics), conversions done today at current rates become retrospectively brilliant—the article's caution about timing could be overly pessimistic about the asymmetry of tax risk.
"Roth conversions are an exercise in tax-rate speculation, not a guaranteed wealth-building strategy, and they require a precise calculation of current tax drag versus future tax liability."
Roth conversions are a classic 'tax arbitrage' play, but they are often mis-sold as a universal panacea. The article correctly identifies the 'gap years'—that window between career cessation and age 73/75 RMDs—as the optimal time to convert. However, it ignores the opportunity cost of paying the conversion tax today. If you pay a 30% marginal rate to convert assets that would otherwise grow tax-deferred, you are effectively cannibalizing your compounding engine. For high earners, the math only works if you expect tax rates to rise significantly or if you are optimizing for estate planning, not just personal cash flow.
The strategy assumes tax rates will remain high or climb, but if Congress shifts to a consumption-based tax model or lowers rates to stimulate growth, you will have permanently overpaid the IRS for a tax-free benefit that never materialized.
"N/A"

"Targeted Roth conversions in low-income pre-retirement years can materially boost after-tax retirement income for high earners, provided IRMAA and tax bracket math are modeled precisely."
Solid reminder for high earners: use pre-RMD low-income windows (post-job, pre-73) for partial Roth conversions to secure tax-free growth and dodge RMDs on converted amounts. Article flags SS taxation (up to 85% at $44k single/$34k provisional income) and IRMAA surcharges (Part B/D premiums jump at $103k/$206k MAGI for 2024, based on prior-year income). Missing: state taxes, estate benefits for heirs (no RMDs/step-up issues), and math—e.g., convert if current marginal rate < expected future blended rate. Bullish for disciplined planners; drives advisor demand amid $40T+ retirement pool.
Conversions lock in today's taxes on principal, but if markets stagnate post-conversion or future rates drop (e.g., via policy shifts), the upfront hit erodes nest egg more than delayed taxation would.
"Conversions are rate-bet vehicles, not universals; article's real sin is treating tax-rate direction as exogenous rather than the core variable."
Gemini's opportunity-cost framing is sharp, but undersells the asymmetry Claude flagged: paying 24% today to avoid 37% later is mathematically different from paying 24% to avoid 24%. The real question isn't whether conversions are universal—they aren't—but whether the article's silence on *rate trajectory probability* (deficit math suggests up, not down) tilts the risk calculus. Grok's state-tax omission is material; a California high earner faces 13.3% state rates on conversions, flipping the entire thesis.
"Roth conversions provide essential income flexibility to minimize total tax drag, which is more critical than simply predicting future federal tax brackets."
Claude and Gemini are debating the tax arbitrage, but both ignore the 'tax-diversification' hedge. Roth conversions aren't just about beating future rates; they provide a liquidity buffer that allows retirees to manage their MAGI annually. By controlling taxable income, you can strategically harvest capital gains at 0% or qualify for ACA subsidies. The real risk isn't just rate trajectory—it's the 'tax-trap' of a 100% tax-deferred portfolio that forces high RMDs, regardless of market conditions.
"Large Roth conversions can trigger multiple, compounding means-tested cliffs that materially raise the true cost beyond the conversion tax."
A single large Roth conversion can produce a cascade of cliff effects few are modeling: it can simultaneously push MAGI over IRMAA, raise taxable Social Security, phase out ACA premium credits, nudge you into higher state brackets, reduce QBI deductions, and even trigger AMT — so your effective marginal tax can exceed the nominal conversion rate. Advisors must run holistic, multi-year simulations across federal, state, Medicare and means-tested benefit thresholds, not just compare current vs. future federal rates.
"Laddered partial Roth conversions neutralize cliff effects and enhance overall after-tax outcomes."
ChatGPT's cascade risks are real for lump-sum conversions, but everyone misses laddering: convert $100k/year over 5 years to stay under IRMAA ($103k single MAGI) and SS thresholds, avoiding cliffs entirely. For a $44k provisional income retiree, this preserves 0% cap gains harvesting too—boosts after-tax returns 8-12% per Vanguard sims. Partial wins over all-or-nothing.
Roth conversions can be beneficial for high earners during low-income years, but timing is crucial due to political volatility and potential long-term impacts on Medicare premiums and other taxes. The opportunity cost of paying taxes upfront and the risk of triggering cliffs should be considered. Laddering conversions over multiple years can help mitigate these risks.
