- Lucas: You hit your FIRE number, you hand in your notice, you're done. Now what? You're 42, you've got a million two in a traditional 401k, and you need income—but if you pull it out before 59 and a half, the IRS hits you with a 10 percent penalty plus ordinary income tax. That's a nasty surprise. Luna: And that's exactly where the Roth conversion ladder comes in. It's one of those strategies that sounds complicated but is actually pretty elegant once you see how the pieces fit. Lucas: Exactly. The core idea: you take pre-tax retirement money—say from a traditional IRA or an old 401k—and you convert a chunk of it to a Roth IRA. You pay income tax on the amount you convert today, at your current marginal rate. Then that money grows tax-free, and after five years, you can withdraw the converted principal completely tax- and penalty-free. Luna: So the key constraint is the five-year clock. Each conversion has its own five-year waiting period, and you need to plan ahead. That's why the ladder works best if you start converting a few years before you actually quit. Lucas: Right. If you're still working and earning a paycheck, you can start the ladder while you're employed. Let's say you're 38, planning to retire at 42. In years one through four, you convert small amounts each year—enough to stay within the 12 percent bracket, say $40,000 to $50,000 depending on your other income. By the time you quit, you've already got a pipeline of Roth principal that's aged past five years and is ready to withdraw. Luna: And during those early retirement years, you're also pulling from your taxable brokerage account, where long-term capital gains are taxed at zero percent if your total income is under about $94,000 for a married couple in 2026. So you can keep your taxable income low while you do the conversions. Lucas: That's the real magic. You're essentially arbitraging tax rates. In your working years, you were probably in the 22 or 24 percent bracket. In early retirement, with no job income, you can live off your taxable account and convert traditional IRA dollars at 12 percent or even 10 percent. Over a decade or two, that difference compounds massively. Luna: Let's put some numbers on it. Say a couple retires at 45 with $1.5 million in a traditional IRA and $400,000 in a taxable brokerage. Their annual spending is $50,000. They sell $50,000 worth of stock in the brokerage each year—half of that is cost basis, half is long-term gain. Their taxable income from that is $25,000, which is below the standard deduction of about $30,000 for a married couple in 2026. So they pay zero federal tax. Lucas: And that leaves them room in the 10 percent bracket. They can convert another $30,000 or so from the traditional IRA to Roth, paying just 10 percent on that conversion. They repeat this every year. After five years, the first conversions are seasoned and can be withdrawn tax- and penalty-free. They now have an income stream that never touches their taxable account again, and the Roth keeps growing. Luna: What about someone who retires earlier, like at 35? They don't have a five-year runway built up. Is there another option? Lucas: They can use the substantially equal periodic payments exception—Section 72t. That lets you take penalty-free withdrawals from an IRA before 59 and a half, based on your life expectancy. The catch: you're locked into that payment schedule for five years or until you turn 59 and a half, whichever is longer. And if you mess up the calculation, the IRS retroactively penalizes all the withdrawals. So it's less flexible than a ladder. Luna: Right. Most early retirees prefer the ladder because you can adjust the conversion amount each year. If your spending goes up one year, you convert less. If you have a big expense, you can pull from the taxable account instead. The ladder gives you control. Lucas: One nuance people miss: when you convert from a traditional IRA to a Roth, the amount you convert is added to your adjusted gross income. That can affect other things—like how much of your Social Security is taxed later, or your eligibility for the premium tax credit on ACA health insurance. So you need to model the interaction. Luna: That's especially important if you retire before 65 and rely on the Affordable Care Act marketplace. A $50,000 conversion might push your income over the threshold for subsidies, effectively costing you thousands more in premiums. So you have to weigh the tax savings against the subsidy loss. Lucas: Absolutely. The decision isn't just 'convert as much as possible at 12 percent.' It's 'convert as much as possible while keeping your modified adjusted gross income below 400 percent of the federal poverty level,' which in 2026 is about $62,000 for a single person. For a couple, it's around $84,000. That's a hard cap for subsidy eligibility. Luna: And if you can keep your income under that, your health insurance premiums are capped at about 8.5 percent of income. That's a huge benefit. A $10,000 conversion that saves you $1,200 in taxes could cost you $4,000 in lost subsidies. The math flips. Lucas: Which brings up another point: the Roth conversion ladder isn't just about early retirement. Even if you plan to work until 65, converting some traditional IRA money during low-income years—like a sabbatical, a career break, or the year after you retire but before you start Social Security—can reduce your required minimum distributions later and lower your lifetime tax bill. Luna: Right. RMDs start at age 73 under the current law, and they can push you into a higher bracket. If you have a $2 million IRA at 73, your first RMD is about $76,000. Add Social Security, maybe a pension, and suddenly you're in the 22 percent bracket or higher. Converting earlier at 12 percent saves real money. Lucas: There's also the 'tax torpedo' effect. When you take Social Security, each additional dollar of other income can cause up to 85 cents of your benefits to become taxable. So a modest RMD can create a surprisingly high effective marginal rate. The strategy is to draw down the traditional IRA before Social Security kicks in—exactly what the ladder does. Luna: Let's talk about the mechanics. How do you actually set up a conversion ladder? Lucas: First, you need a traditional IRA. If you have a 401k from a previous employer, you can roll it into a traditional IRA at any brokerage—Vanguard, Fidelity, Schwab. Then, each year, you submit a Roth conversion request. You specify the dollar amount or the number of shares. The brokerage moves the money from the traditional IRA to your Roth IRA. You'll get a 1099-R next January showing the conversion, and you report it as income on your tax return. Luna: Important detail: you can convert as much as you want—there's no limit. But you can't undo it. Once you convert, the money is in the Roth. If the market drops and you wish you'd converted less, too bad. So it's smart to convert in stages rather than all at once. Lucas: And you should pay the tax from outside the IRA—ideally from your taxable account. If you withhold the tax from the conversion itself, that withheld amount counts as an early distribution and is subject to the 10 percent penalty if you're under 59 and a half. So you want to pay the tax with other money. Luna: That's a common mistake. You convert $30,000, have $3,000 withheld for taxes, and end up with a $27,000 conversion that you'll owe penalty on that $3,000. Avoid that. Lucas: If today was actually useful to you, the way these stay ad-free is listener support. Buy me a coffee dot com slash fexingo keeps the lights on and the episodes coming without sponsors. Luna: Yeah, we really appreciate everyone who chips in. It means we can keep digging into these details without worrying about selling you something. Thanks for being part of it. Lucas: So back to the ladder—one strategy that I think is underused is converting in-kind. Instead of selling your investments and moving cash, you can transfer the actual shares from your traditional IRA to your Roth. That way you stay invested, and if the market goes up before you withdraw, the gains are already in the Roth. Luna: That's a good tip. And for people with large traditional IRAs, you might want to convert only up to the top of the 12 percent bracket each year for a decade. If you're single, that's about $47,000 in 2026. Over ten years, that's $470,000 moved to Roth, paying only 12 percent. That could save you hundreds of thousands in future taxes. Lucas: Let's look at the bigger picture. Someone with $2 million in a traditional IRA, retiring at 50. They have 23 years before RMDs start. If they convert $50,000 each year for 20 years, they've moved $1 million to Roth, paid maybe $100,000 in total taxes at 10 and 12 percent. The remaining $1 million, plus growth, will still generate RMDs, but much smaller ones. Meanwhile, the Roth money grows tax-free and can be inherited tax-free by their kids. Luna: And the inherited Roth IRA for non-spouse beneficiaries has to be withdrawn within ten years under the SECURE Act, but those withdrawals are tax-free. That's a huge estate planning benefit. Lucas: One more risk to mention: the government could change the rules. There's been talk of eliminating the Roth conversion ladder or limiting conversions after a certain income level. But so far, the strategy is still intact. The best hedge is to diversify—have some money in taxable, some in traditional, some in Roth—so you're not dependent on any one rule. Luna: Speaking of diversification, what about using a Roth ladder in conjunction with a 72t distribution? Can you do both? Lucas: You can, but you have to keep the money separate. You can set up a 72t on one IRA account and do conversions on another. The 72t payments are fixed, so they fill up your low tax brackets, leaving less room for conversions. It's often better to just use the ladder if you can plan ahead. Luna: So to sum it up: the Roth conversion ladder is a powerful tool for early retirees to access retirement funds penalty-free and manage taxes over a lifetime. The key is to start early, convert gradually, and watch your total income to preserve ACA subsidies and keep your tax rate low. Lucas: Exactly. And the best part is, once the ladder is set up, you have a steady stream of tax-free income that's completely under your control. No RMDs, no penalty worries, just flexibility. That's the kind of freedom that makes early retirement work.
