Should I Convert $130,000 a Year to a Roth to Avoid RMDs? I'm 59 With $1.3 Million in a 401(k)

Converting a 401(k) into a Roth IRA can be appealing for several reasons. Not only can you make qualified withdrawals from Roth accounts tax-free, but Roth accounts are also exempt from required minimum distributions (RMDs.) That can give you more flexibility when withdrawing from your account in retirement and potentially save you money on taxes.
Imagine you’re nearing retirement age and have $1.3 million in a 401(k). Converting the whole balance in one fell swoop could leave you with a massive tax liability. On the other hand, converting your 401(k) gradually over the course of a decade can reduce taxes compared to converting it all in a single transaction.
While you could start converting $130,000 annually, you may want to change that amount later on depending mostly on how the investments in your 401(k) perform.
If you’re thinking about a Roth conversion or need help planning for your RMDs, consider working with a financial advisor.
Impact of Roth Conversions on RMDs
RMDs withdrawals you’re required to take from tax-deferred retirement accounts starting at age 73 (the RMD age rises to 75 for anyone who turns 74 after Dec. 31, 2032). These withdrawals are treated as ordinary taxable income, so RMDs can push you into a higher tax bracket and increase your tax bill.
For example, if you have $1.3 million in your 401(k) at age 59 and earn 4% annually for the next 14 years, your 401(k) could grow to more than $2.77 million. When you start taking RMDs after turning 75 (due to the Secure 2.0 Act, beginning RMD age shifts from 73 to 75 starting in 2032), your first RMD could be over $104,000. If you are a single filer whose only other taxable retirement income is $25,000 in Social Security benefits, that would increase your marginal tax rate from 12% to 24% (using the 2025 tax brackets).
Avoiding RMDs isn’t the only reason to consider a conversion. You may also want to convert if you think you’ll be in a higher tax bracket after you retire. Also, Roth accounts can make bequeathing your wealth to your heirs easier, so a conversion can be a useful estate planning tool. But if you need help deciding whether a Roth conversion is suited for your situation and goals, connect with a financial advisor and talk about it.
Conversion Strategies
If you convert $1.3 million in one lump sum, this would put you in the highest marginal tax bracket – 37% – and require paying over $430,000 on your next tax return. Making a series of annual $130,000 conversions over the next 10 years could reduce this tax bill significantly.
Assuming for the sake of illustration that each year you have $60,000 in other taxable income after deductions and credits, your annual income over the conversion period will be $190,000. As a single filer, that will put you in the 24% bracket and require paying approximately $35,000 per year in taxes (assuming you take the standard deduction). Over the 10-year conversion period you’d hypothetically pay more than $350,000 in taxes but potentially save approximately $80,000 compared to doing a lump-sum conversion.
In some situations, you could use other conversion strategies. For instance, if you expect to have lower income one year, you could convert a larger amount. The central idea is to convert just enough of your 401(k) savings to bring your taxable income up to the next tax bracket threshold – but not past it. If you’re interested in Roth conversions or other tax planning strategies, consider working with a financial advisor.
Roth Conversion Caveats
Converting 401(k) funds into a Roth account can make financial sense, but there are some risks and limits to this move. To begin with, you may have to wait five years after establishing a Roth IRA to withdraw any investment earnings from the account. Running afoul of this rule can trigger income taxes and potentially a 10% early withdrawal penalty.
There’s also a separate five-year waiting period that applies specifically to Roth conversions. The IRS requires you to wait five years from the start of the year in which you completed a conversion before you can withdraw any of the money that’s converted. However, this particular five-year rule doesn’t apply to people who are 59 ½ or older.
If you set up your Roth now at age 59 and start taking withdrawals before you are 64, you may have to pay taxes on some of the withdrawals.
Also, implementing a Roth conversion strategy calls for making forecasts about future tax rates and the return your investments will earn. Forecasting involves risk because events may turn out differently. For instance, if you expect future tax rates to be lower and they increase, as current law calls for, you might have been better off to convert more now.
You might also wish you’d converted more if your investments generate higher returns than expected. That could cause your 401(k) to have more money than you expect when you complete your conversion plan, so that you still have to take RMDs.
Finally, if there is any money left in your 401(k), do not neglect to take RMDs as mandated. If you do that, you could owe a penalty of 25% of the amount you should have withdrawn as an RMD. And remember, a financial advisor can help you plan for RMDs and their tax impact.
Bottom Line
Converting funds from a 401(k) or other tax-deferred retirement account can help you avoid RMDs and potentially reduce your tax liability. Gradually converting a portion of your 401(k) each year may make sense as a way to reduce your current tax bill. However, you may have to be flexible about the amount you convert if tax rates or your investment returns turn out differently than you planned.
RMD Planning Tips
If you have tax-deferred retirement accounts, you’ll want to get a sense of how much your RMDs could be and plan for their tax impact. Calculating your RMDs on your own is relatively easy, but SmartAsset built an RMD calculator to make it even easier. The free tool can help you estimate how much your first RMD will be and when it’s required to be taken.
Deciding how to move funds from a 401(k) to a Roth account calls for carefully evaluating your options. A financial advisor can help with that. Finding a financial advisor doesn’t have to be hard. SmartAsset’s free tool matches you with vetted financial advisors who serve your area, and you can have a free introductory call with your advisor matches to decide which one you feel is right for you. If you’re ready to find an advisor who can help you achieve your financial goals, get started now.
Keep an emergency fund on hand in case you run into unexpected expenses. An emergency fund should be liquid -- in an account that isn't at risk of significant fluctuation like the stock market. The tradeoff is that the value of liquid cash can be eroded by inflation. But a high-interest account allows you to earn compound interest. Compare savings accounts from these banks.

Four leading AI models discuss this article
"The choice to convert hinges more on expected future tax rates and personal liquidity than on the RMD avoidance alone; misjudging either can swing the outcome significantly."
The article frames Roth conversions as a clean hedge against RMDs with predictable tax savings from gradual, $130k/year moves. But its math rests on brittle assumptions: stable future tax rates, consistent investment returns (it cites 4%), and no state taxes or Medicare surcharges. It ignores IRMAA (Medicare surcharges tied to MAGI), potential changes to RMD timing, and the SECURE Act 2.0 10-year rule for inherited Roths. A $1.3M conversion over 10 years can trigger large year-by-year tax bills and may require liquidity. Real-world outcomes depend on tax law, portfolio performance, and personal liquidity, making the decision highly scenario-dependent.
If you believe long-run tax rates will rise, front-loading conversions could be more valuable than the article implies; the upside of tax-free growth and tax-free withdrawals for heirs may outweigh the current-year tax bite. So the cautious stance may undervalue the upside of upfront conversion.
"Roth conversions often prioritize tax-bracket optimization over the mathematical reality of lost compounding power on the cash used to pay the conversion taxes."
The article promotes a standard 'tax-bracket arbitrage' strategy, but it ignores the opportunity cost of paying the conversion tax bill today. By liquidating assets to cover the 24% tax hit, the investor sacrifices potential compounding on those tax dollars. If the $35,000 annual tax payment were instead invested in a taxable brokerage account, the drag on the portfolio's total return could outweigh the benefit of avoiding future RMDs. Furthermore, the article assumes current tax brackets remain static, ignoring the sunsetting of the Tax Cuts and Jobs Act in 2026, which will likely push marginal rates higher for everyone, potentially making the 'cheaper' conversion window smaller than anticipated.
If the investor's heirs are in a significantly higher tax bracket, the Roth conversion acts as a massive tax-advantaged wealth transfer vehicle that justifies the current-year tax drag.
"The article's tax math is incomplete without knowing the reader's full pre-tax IRA balance, which determines pro-rata rule exposure and could double the effective tax cost of conversions."
This article treats Roth conversion as a tax-optimization puzzle, but misses the elephant: pro-rata rule exposure. The reader has $1.3M in a 401(k) but likely has other pre-tax IRA balances (SEP, Traditional IRA, old 401(k) rollovers). Converting $130k annually triggers pro-rata taxation on the entire pre-tax IRA universe—not just the amount converted. The article's 24% tax estimate assumes clean conversions; reality could be 32-35% if hidden pre-tax balances exist. Also glossed over: state income tax (could add 5-10%), Social Security taxation thresholds (conversions trigger IRMAA Medicare premiums at 59), and the fact that $1.3M growing at 4% for 14 years assumes zero withdrawals—unrealistic if the person needs retirement income now.
If tax rates genuinely rise post-2025 (as the article hints), converting at today's 24% marginal rate locks in a 13-point arbitrage versus potential 37% future rates—making the $350k tax bill look cheap in hindsight. The article may be underweighting the real risk: NOT converting enough.
"Market returns above the article's 4% assumption can leave substantial RMD exposure despite a decade of conversions."
The article's gradual $130k annual Roth conversion plan from a $1.3M 401(k) assumes 4% returns and static 24% brackets to cap taxes at ~$350k versus a lump-sum hit. Yet it understates sequencing risk: equity-heavy portfolios often deliver 7-8% long-term returns, potentially leaving $1M+ in the account after 10 years and still triggering RMDs above the 24% threshold once brackets revert post-2025. The five-year conversion clock and possible 10% penalties before 64 further erode flexibility for anyone retiring earlier than projected. Liquidity needs and state tax interactions receive no mention.
Even with higher returns, spreading conversions still keeps marginal rates lower than a single-year spike to 37% and preserves optionality if tax law changes.
"The pro-rata rule can drastically raise the effective tax rate on annual Roth conversions, invalidating the article's clean 24% assumption."
Claude highlights pro-rata risk, but the math is worse in practice: the taxable portion of each $130k conversion isn't just 24%—it's determined by your total pre-tax IRA balances. If you have SEP/Traditional IRAs or old 401(k) rollovers, the blended balance can lift the effective rate on a given conversion toward the mid-30s% range, plus state taxes and potential IRMAA. That undermines the clean arbitrage the article assumes.
"The urgency of locking in current tax rates before the 2026 TCJA sunset outweighs the concerns regarding pro-rata complexity and liquidity drag."
Claude and ChatGPT are correct on pro-rata risks, but everyone is ignoring the 'tax-bracket cliff' post-2025. If the TCJA sunsets, the 24% bracket jumps to 28% or higher. We are debating the math of a 24% conversion while the real risk is that the window to convert at sub-30% rates is closing rapidly. The primary danger isn't the tax drag on liquidity; it's the failure to capture these historically low rates before federal policy shifts.
"Tax-rate timing is a bet, not a certainty; spreading conversions hedge that bet better than rushing to beat 2025."
Gemini's 2025 tax-cliff argument is sound, but it conflates two separate risks. The TCJA sunset is real—but conversions locked in today are *irrevocable*. You pay 24% now; future RMDs hit at 28%+. The arbitrage works *if rates rise*. But Gemini hasn't addressed: what if Congress extends TCJA again (happened before)? Then you've front-loaded taxes for no gain. The real edge isn't predicting rates—it's optionality. Spreading conversions preserves it.
"Spreading conversions sacrifices the narrowing pre-2026 window rather than preserving flexibility."
Claude's optionality argument for spreading conversions ignores the hard deadline: TCJA sunset hits in 2026, so gradual $130k moves risk executing most conversions at 28%+ if brackets revert without extension. The five-year clock then locks in higher effective costs without the assumed 24% arbitrage, especially once IRMAA and state taxes layer on.
