- Lucas: So we get a version of this question every few months in the listener mailbag: 'I earn too much for a Roth IRA, what do I do?' And the answer — well, the clever answer — is something called the Backdoor Roth IRA. Luna: And I think a lot of people hear 'backdoor' and assume it's shady or a loophole that'll get closed. But it's literally just a two-step process that's perfectly legal. Lucas: Right. The IRS sets income limits for direct Roth IRA contributions. In 2026, if you're single and your modified adjusted gross income is over $161,000, you can't contribute directly. For married filing jointly, the phase-out starts at $240,000. Luna: Which is exactly where a lot of dual-income professionals and early retirees with side hustles land. Lucas: Exactly. So the backdoor Roth works like this: You contribute to a traditional IRA — which has no income limit — and then you convert that contribution to a Roth IRA. The conversion is a taxable event only if you had pre-tax money in the traditional IRA. But if the contribution was non-deductible — meaning you already paid taxes on it — then the conversion is tax-free. Luna: Wait, so you have to make sure you're not deducting that traditional IRA contribution on your taxes? Lucas: Correct. And for most high earners, the traditional IRA contribution is non-deductible anyway because their income exceeds the limit for deductibility. So you're effectively putting after-tax money into a traditional IRA, then converting it to Roth. The IRS gets its taxes on the front end, and you get tax-free growth on the back end. Luna: Let's walk through the actual steps, because I think people get tripped up on the mechanics. Lucas: Sure. Step one: Open a traditional IRA if you don't have one. Step two: Contribute the maximum — for 2026 that's $7,000 if you're under 50, $8,000 if you're 50 or older. Step three: Once the money settles, convert the entire balance to your Roth IRA. That's it. You'll get a Form 5498 from your broker showing the contribution, and a Form 1099-R for the conversion. Luna: And you want to do the conversion quickly — ideally within a day or two — because any growth that happens in the traditional IRA before conversion is taxable. Lucas: Right. If the $7,000 earns $50 of interest before you convert, that $50 is taxable as ordinary income. So you want to minimize the gap. Most brokers let you do the conversion online in a few clicks. Luna: Okay, but here's where the 'pro-rata rule' rears its head. What if you already have a traditional IRA with a big pre-tax balance? Lucas: That's the trap. The IRS doesn't let you cherry-pick which dollars you convert. If you have a traditional IRA with, say, $100,000 in pre-tax money and you make a $7,000 non-deductible contribution, then when you convert, the IRS treats the conversion as proportional. So 100,000 divided by 107,000 — about 93.5% of the conversion would be taxable. Luna: Which defeats the purpose. So if you have a large traditional IRA balance, the backdoor Roth isn't as clean. Lucas: Unless you can roll that pre-tax money into an employer plan like a 401 before December 31st of the year you do the conversion. Many 401 plans accept rollovers from IRAs. If you can clear out the pre-tax money, then the backdoor Roth works cleanly. Luna: And there's also the 'mega backdoor Roth' for people with a 401 that allows after-tax contributions. Lucas: Right. That's a different animal. With a mega backdoor Roth, you're using the after-tax contribution bucket inside your 401. Some plans let you contribute up to the total 401 limit — $70,000 in 2026 — including employer match and pre-tax deferrals. So if your pre-tax deferrals are $23,500 and your employer matches $5,000, you can contribute up to $41,500 in after-tax money, then convert that to Roth 401 or Roth IRA. Luna: That's a huge amount of additional Roth space. But not all plans offer it, and you have to check if your plan allows in-plan Roth conversions or in-service distributions. Lucas: Big caveat. If your plan doesn't allow it, you can't do it. But if it does, it's an incredibly powerful way to supercharge your tax-free savings. I know a couple in their early 40s who each max out the mega backdoor Roth through their Fidelity 401s. They're adding about $80,000 a year to Roth accounts on top of their regular Roth IRAs. Luna: And that's money that will never be taxed again. For early retirees, having a big Roth balance is gold because you can withdraw contributions tax-free and penalty-free at any age. Lucas: Exactly. That's the key point. Roth IRA contributions — not earnings, but contributions — can be withdrawn anytime without tax or penalty. So if you retire at 45 and need cash, your Roth contribution basis is a great source. And after age 59 and a half, all earnings are tax-free too. Luna: Let me ask a practical question: What about the tax reporting? I've heard people say the paperwork is annoying. Lucas: It's a little more involved than a standard contribution, but it's manageable. You'll need to file Form 8606 with your tax return to track the non-deductible contribution basis. If you convert the same year, Part II of Form 8606 handles the conversion. Tax software like TurboTax walks you through it, but you have to answer the questions carefully. Luna: And if you don't file Form 8606, the IRS might assume the conversion is fully taxable. So don't skip it. Lucas: Yeah. And one more gotcha: the 'step transaction doctrine.' Some tax professionals worry that if you contribute and convert too quickly, the IRS might recharacterize it as a direct Roth contribution that exceeds the income limit. But the IRS has issued guidance — Notice 2009-32 and subsequent rulings — affirming that the backdoor Roth is valid as long as you follow the steps. It's not a loophole; it's a straightforward use of the tax code. Luna: Good. So let's sum up: If you earn too much for a direct Roth IRA, you can still get money into a Roth by making a non-deductible traditional IRA contribution and converting it. Avoid this if you have a large pre-tax IRA balance you can't roll into a 401. And if your 401 allows after-tax contributions, consider the mega backdoor Roth. Lucas: Perfect summary. And for early retirees, this is one of the most effective ways to build tax-free income for the long haul. It's not flashy, but it works. Luna: You know, if this episode has been useful to you — and I hope it has — one way to keep the content coming without ads is to throw a few bucks our way. It's buy me a coffee dot com slash fexingo. Lucas: Yeah, listener support is what keeps this show independent. We don't do sponsor reads or affiliate links. So if you got value, that's the place. Luna: And if you have a specific scenario you want us to tackle — maybe you have a traditional IRA from an old 401 and you're wondering if the backdoor Roth still makes sense — drop us a note. Lucas: We'll get to it. For now, look at your own IRA situation. If you're over the income limit, the backdoor is a simple move that can add decades of tax-free growth. It's worth the extra few clicks.
