The mega backdoor Roth: up to $47,500 more into a Roth

0:00 $47,500. That's how much extra money you might be able to put into a Roth this year on top of your regular 401k completely legally. Not the $7,000 Roth IRA, not the backdoor Roth you've maybe heard about. $47,500 growing tax free for the rest of your life. Now, most high earners think that once they max their 401k that they're done. There's a ceiling, they hit it, and that's it. But, for a lot of you, that's wrong. And there's a whole second floor above the one you've been standing on. If your household is making somewhere between 250 and 500,000 dollars, and you're already maxing your 401k, this next 10 minutes is built specifically for you. I'm going to build the number from scratch so you can see exactly where it comes from, run it across three different incomes, and then show you the two things that your plan has to allow because if it doesn't, and I'm going to tell you how to check that in about 90 seconds. A Roth is the best retirement account there is for a lot of high earners. You put money in that you already paid tax on, it grows, and you never pay tax on it again. No tax on the growth, no tax on the withdrawal in retirement. For someone who expects to have a serious nest egg, that's enormous. But, here's the catch. The normal Roth IRA has an income limit. In 2026, once a married couple's income passes $242,000, the amount you're allowed to contribute starts shrinking.

0:57 And by $252,000, it's gone completely. So, if you're the household this video's for, you're probably already locked out of your regular Roth IRA. You just make too much. That's where the regular backdoor Roth comes in. And if you're doing that, then good, keep doing it. But, that move is still capped at $7,000 per year. And $7,000 is fine, but it's not going to change your retirement. The mega backdoor Roth is a different animal, and it lives inside your 401k, not your IRA. To see where that $47,000 comes from, I need to show you something about your 401k that most people never looked at. Your 401k isn't one bucket, it's three. And almost everyone only ever fills the first one. Bucket one is your normal contribution, the money that comes out of your paycheck before you ever see it. In 2026, you can put in $24,500. If you're 50 or older, you get an extra $8,000 on top of that. This is the bucket everyone knows about, and maxing is what makes most people think they're finished. Bucket two is your employer match. Whatever your company kicks in, that's their money added to your account. Now, here's the number that almost nobody knows. The IRS doesn't cap your 401k at $24,500. That's just the cap on your bucket. The real ceiling, the total of everything that can go into your 401k from all sources in 2026, is $72,000. So, take that ceiling, subtract your $24,500, subtract whatever your employer puts in, and whatever is left is bucket three, the after-tax bucket. That's the space the mega back door Roth fills. Let's say your employer puts in $10,000 in match.

2:02 $72,000 minus your $24,500 minus your $10,000 leaves you $37,500 of room in that third bucket. And if you happen to work somewhere with no match, then that third bucket is even bigger. $72,000 minus $24,500 is $47,500. So, you fill that third bucket with after-tax dollars, but here's the thing, after-tax money sitting in a 401k isn't special on its own. It grows tax deferred, but not tax free. The magic is the second step. You can convert that after-tax money into Roth money. And there's two ways that happens depending on your plan. Some plans let you do an in-plan Roth conversion where the money just flips to Roth inside the 401k. Others let you roll it out to a Roth IRA while you're still working, which is called an in-service distribution. Either one gets you to the same place. That money is now in Roth, and it will never be taxed again. Now, let's talk about the one mistake that quietly costs people money. You want that conversion to happen fast, ideally right after the money goes in, and here's why. If you let after-tax money sit for months, it earns gains. And when you convert, those gains are taxable because they were never taxed before. Convert quickly, and there are almost no gains to tax, so the whole thing moves over clean. Now, here are the best setups to do this automatically. It's sometimes called an automatic in-plan Roth conversion, and if your plan offers it, every tax dollar sweeps to the Roth the moment it lands.

3:03 Gains never build up, and you don't have to think about it. If your plan makes you do it manually, then that's fine as well. You just want to do it on schedule and not let it drift. So, fill the third bucket, convert it fast, and you've moved as much as $47,500 a year into tax-free growth that a normal Roth IRA would have never let you touch. Now, at the beginning of the video, I promised I'd run this across three incomes because the size of your third bucket depends entirely on your salary, your match, and what your plan allows. The first scenario, let's call her Dana, software engineer in Austin. She's single, $290,000 per year, and her employer matches 4%, which on her salary is about $11,600. She maxes her $24,500, so her after-tax room is $72,000 minus the That leaves about $35,900 that she can put into a third bucket and convert it to Roth. Now, Dana's single, so the regular Roth IRA has been closed to her for years because of the income limit. This is the only way she gets serious Roth money, and And just found almost $36,000 of it in an account she already had. Let's go over scenario two, which is a married couple. They're both high earners. Let's say one's in medical device sales and she's an in-house counsel. Their combined income is $450,000. The strategy lives inside each person's own 401k. So, if both of their plans allow it, they each get their own third bucket. Let's say his plan gives him a $6,000 match and hers gives her eight. His after-tax room comes to around $41,500 and hers is around $39,500. Add those across the household and it's over $80,000 a year going into Roth from two different plans in a single year. That's the kind of number that quietly builds a seven-figure

4:20 tax-free account faster than most people think is possible on a W-2. Now, scenario three, this one's the reality check because I don't want you to walk away thinking that it's always $47,000. Let's say there's a guy at a company with a very generous match at 12%. And this is on a $260,000 salary. That match is over $31,000, which is a great problem to have. But, watch what it does to the third bucket. $72,000 minus the $24,500 minus the $31,000 leaves only about $16,300 of after-tax room, which is still absolutely worth doing. It's just smaller because a big match eats into the same $72,000 ceiling that everything else has to fit under. Now, this is at the point where a lot of people get excited and then they get stuck. The question I always get next, "Does my plan actually allow this and how do I coordinate it with my match and my cash flow so I don't mess it up?" That's exactly what we're going to walk through in my free masterclass this week. We look at your actual plan, your income, and your match and we figure out how big your third bucket really is and whether your plan lets you convert it. It's the difference between watching this and actually doing it. The link is in the description and in the pinned comments. Now, let's go over the two requirements I keep mentioning and this is where most people find out whether they're in the club or not. Here's the honest part. The mega backdoor Roth is incredible and most 401k plans don't allow it. So, before you get attached, you need to check two things and both have to be true. The first requirement is your plan has to allow after-tax contributions and I mean specifically after-tax, which is a separate thing from a Roth 401k option. This is the part a lot of people trip on and it's the single most common mistake I see when someone tells me that they're already doing it. A Roth 401k contribution is money you put in from your paycheck up to $24,500.

5:37 An after-tax contribution is a completely different bucket that lets you go above it all the way to $72,000. It's the same word Roth floating around both, but totally different mechanics. You're looking for the phrase after-tax listed as its own contribution type in your plan, separate from pre-tax and separate from Roth. Now, the second requirement is your plan has to let you move the after tax money into Roth while you still work there. That's the in-plan Roth conversion or the in-service distribution I mentioned. If the money is trapped until you quit or retire, the strategy loses most of its value because it just sits there as after tax money growing taxable. And the growth becomes a taxable later instead of tax-free income. Now, here's exactly how I check and it takes 5 minutes. Log into your 401k portal or pull up the document called your summary plan description and search for two phrases. After tax contributions and in-service distributions or in-plan Roth conversion. If both show up, your plan supports this and you should be looking hard at it. If you only find one or neither, call your HR or your plan administrator and ask them directly in those words. Now, one more warning because I've watched smart people get this wrong. Do not confuse this with the internet advice telling you to just contribute a giant amount to your Roth 401k and call it a mega backdoor. That's not the same thing. And if you blow past your plan's limits or contribute after tax when your plan doesn't actually support the conversion step, you create a mess with excess contributions that you have to unwind. The strategy only works cleanly when the plan is built for it. When it isn't, forcing it costs you time and sometimes penalties. Now, I want to be straight with you about who this is not for because I'd rather you spend your money right than spend it here. If you haven't maxed your regular $24,500 first, then do that before you

6:54 even think about this because that money often goes in pre-tax and lowers your tax bill today, which the after tax bucket does not. The order is simple. Capture the full match first and then max your own contribution and then look at the third bucket. If your cash flow is tight and you'd be locking away money that you actually need in the next few years, this is not your move this year and that's fine. And if your plan simply doesn't allow it, no amount of wanting it changes that. Put your energy into a taxable brokerage account and invest it tax efficiently or back to a Roth IRA or an HSA if you have a high deductible plan. Those are the fallbacks and they're good ones. Now, let me talk about why this is worth the trouble. Let me show you what filling the bucket actually builds because the annual number is nice, but the compounding is the whole point. Let's take someone who can put in the full $47,500 per year and let's say they do it for 20 years and their investments grow at a reasonable long-term rate. Even before we count a dollar of growth, that's about $950,000 of contributions. With two decades of compounding on top of that, you're realistically talking about a Roth balance well into the seven figures. And here's the part that matters. Every dollar of it comes out tax-free in retirement. There's no tax on the withdrawals, there's no required minimum distributions forcing money out on the government schedule, and nothing added to your taxable income when you pull it.

7:52 You compare that to the same money sitting in a regular brokerage account. In the brokerage account, you pay tax on your dividends every single year along the way, and you pay capital gains tax every time you sell. Over 20 years, that yearly tax drag quietly skims a real chunk off your returns, and depending on your bracket and your state, it can add up to a six-figure difference on a balance this size. The mega-backdoor Roth erases that drag entirely. Same investments, same contributions, but one version of it hands a slice to the IRS every year, and the other one doesn't. Now, let me answer a question that some of you guys are probably asking right now, which is why bother with the Roth at all instead of just putting more into a pre-tax? For higher earners who expect to have a large balance and real income in retirement from other accounts, from real estate, maybe from selling a business, tax-free is worth a lot more than it sounds. Pre-tax money gets taxed on the way out at whatever rates exist decades from now, and nobody thinks rates are heading down long-term. Pre-tax money also triggers required minimum distributions that force money out on the government schedule whether you need it or not. Roth money has none of that. You control when it comes out, it comes out tax-free, and it doesn't inflate your taxable income in retirement. For this income bracket, that control is a big part of the point.

8:46 And remember, this stacks on top of everything else you're already doing. Your match still happens, your regular $24,500 still goes in, and still lowers your taxable income this year. This third bucket is additional room and not a trade. You're adding a whole second floor above the ceiling you thought you already hit. Now, I want to name one honest complexity because it's real. Doing this right means coordinating the after-tax contribution with your match timing. Some plans only give you the full match if you spread your contributions across the whole year. So, if you rush and fill everything in the first few months, you can accidentally leave match money on the table. Others have a true-up that fixes it for you, but knowing which kind you have matters, and is exactly the sort of detail worth a second set of eyes before you set it up. Now again, if you want the full picture, how big your third bucket actually is, how to coordinate it with your match, and how it fits with everything else in your situation, I'm hosting a free masterclass this week where we're going to go more in-depth on this.
