Transcript
- Lucas: If you're aiming for early retirement — say, walking away from your job at 45 — you've probably spent hours on your withdrawal rate, your asset allocation, your sequence of returns risk. But there's a tax you may not have budgeted for, and it's quietly taking a cut of your investment income before you even touch it. Luna: You're talking about the net investment income tax. The NIIT. It's been around since 2013, but I think a lot of early retirees barely have it on their radar. Lucas: Exactly. The NIIT is a 3.8 percent surtax on the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds a threshold: two hundred thousand dollars for single filers, two hundred fifty thousand for married couples filing jointly. That's not a typo — those numbers are not indexed for inflation, so every year, more people get pulled in. Luna: Right, and that's the kicker. If you retired at 45 and you've got a taxable brokerage account generating dividends and capital gains, your income might look low on paper, but add in a Roth conversion or a part-time gig, and suddenly you're over the threshold. Lucas: Let me give a concrete example. Say you and your spouse have one point five million dollars in a taxable brokerage account. You plan to withdraw four percent a year — that's sixty thousand dollars. If that's your only income, you're in the zero percent long-term capital gains bracket, and you pay zero federal income tax. But then you decide to do a Roth conversion of forty thousand dollars to build up your tax-free bucket. Now your income is a hundred thousand. Still way below the two hundred fifty thousand threshold, so no NIIT. Luna: Okay, but what if one of you picks up a consulting gig that pays sixty thousand a year? Now your combined income is a hundred sixty thousand. Still under the threshold. But what if you also sell a rental property that year? Lucas: That's exactly where it gets you. Suppose you sell a rental property and realize a hundred thousand dollars in capital gains. Now your total income is two hundred sixty thousand. You're ten thousand over the two hundred fifty thousand threshold. The NIIT applies to the lesser of your net investment income — that's the rental gain plus any dividends and interest — or your excess income above the threshold. In this case, your net investment income might be a hundred twenty thousand, and your excess is ten thousand. So you pay 3.8 percent on ten thousand dollars — three hundred eighty bucks. Luna: So it's not going to break you, but it's a stealth cost that piles up over time. And if you're doing larger conversions or have bigger gains, it can be thousands. Lucas: Exactly. And here's the thing — the NIIT doesn't just apply to capital gains and dividends. It also covers interest, rental income, royalties, and income from businesses that are considered passive. So if you're a limited partner in an LLC that throws off income, that's potentially subject to NIIT too. Luna: Is there any way to avoid it entirely? Or at least minimize it? Lucas: There are a handful of strategies. First, manage your modified adjusted gross income to stay under the threshold. That might mean deferring capital gains, doing smaller Roth conversions over multiple years, or using tax-loss harvesting to offset gains. Second, consider municipal bonds — their interest is generally exempt from federal income tax and also from NIIT. Third, if you have a side business that generates active income, you can use retirement plan contributions to lower your MAGI. Luna: And there's also the option to live off of cash or a Roth IRA for a year to intentionally keep your income low. That way you can do a larger conversion the next year without triggering NIIT. Lucas: Right. Another angle — if you have a health savings account, contributions reduce your MAGI and are triple tax-free. So maxing that out can help keep you under the threshold. And don't forget about the 3.8 percent additional Medicare tax on earned income. That applies to wages and self-employment income above the same thresholds. So if you're working part-time in retirement, you could get hit with both taxes. Luna: That's the one-two punch. You're paying 3.8 percent on your investment income and 3.8 percent on your earned income above the threshold. That's almost eight percent in additional taxes on top of your regular brackets. Lucas: And again, those thresholds are not indexed for inflation. In 2026, two hundred fifty thousand dollars doesn't go as far as it did in 2013. By the time you retire, more and more of your income could be subject to NIIT unless you plan for it. Luna: So what's the one takeaway you want listeners to walk away with? Should they be scared of NIIT? Lucas: No, not scared. But aware. If you're running your retirement numbers and you're assuming zero tax, double-check. Factor in a potential 3.8 percent surtax on your investment income if your total income pushes above that two hundred fifty thousand line. And if you're doing Roth conversions or selling assets, try to spread them out so you stay under the threshold in any given year. Luna: And if you're already in the accumulation phase, consider using tax-deferred accounts like traditional IRAs or 401s to keep your taxable income lower in early retirement. Then you can control your MAGI more carefully. Lucas: Exactly. The NIIT is one of those taxes that doesn't get a lot of attention because it only kicks in above a certain level. But for early retirees who have built a decent nest egg, it's a very real consideration. And with the thresholds frozen, it's only going to become more common. Luna: I think it's also worth mentioning that state taxes can compound the issue. Some states have their own surtaxes on investment income. So if you're in California or New York, your effective tax rate could be significantly higher. Lucas: Great point. And that's why we keep coming back to the idea of geographic arbitrage in financial independence. Moving to a state with no income tax — like Texas, Florida, or Nevada — can save you a bundle, both on regular income tax and on niit style surtaxes. Luna: And if you're thinking about retiring abroad, keep in mind that the NIIT applies to U.S. citizens and permanent residents regardless of where they live. So moving overseas doesn't exempt you from it. Lucas: Which brings me to one more strategy: if you're a renter, or you don't have a permanent home, you could potentially arrange your affairs to keep your MAGI below the threshold by using a Roth IRA ladder and living off of contributions. But that's a more advanced move. Luna: You know, it's funny — we spend so much time optimizing for returns and minimizing fees, but taxes are often the biggest expense in retirement. And NIIT is one of those hidden ones that can easily slip through the cracks. Lucas: Absolutely. And that's the theme of this whole podcast, right? The small details that make a big difference over a thirty or forty year retirement. The NIIT might only cost you a few hundred bucks some years, but over a lifetime, that compounds. Luna: Speaking of things that make a difference — a lot of you have asked how we keep this show going without ads. And the answer is: listener support. A couple of dollars a month from people who find value in these conversations genuinely makes it possible for us to keep doing this. Lucas: Yeah, if you've gotten something out of our episodes — maybe a tax strategy you didn't know about, or a clearer picture of your withdrawal plan — you can help us keep the show ad-free and accessible. It's buy me a coffee dot com slash fexingo. No pressure, just a way to say thanks if you feel like it. Luna: And it really does add up. Even a few dollars helps cover hosting and production. We're grateful for every bit of support. Lucas: Alright, back to the NIIT. I want to run through one more scenario that people miss. Say you're doing a Roth conversion and you also have a high-dividend stock in your taxable account. The dividends alone might push you over the threshold if you're not careful. Luna: Right, because dividends are investment income. So if your dividends total thirty thousand and you do a forty thousand conversion, that's seventy thousand. If you have even a small part-time job that adds sixty thousand, you're at one thirty. Still under two fifty. But if you add a capital gain from rebalancing, it can add up fast. Lucas: Exactly. That's why I recommend doing a rough projection each year. Estimate your dividend and interest income, any capital gains you might realize, and any Roth conversions. Add in any side income. If you're within fifty thousand of the threshold, think about whether you can defer something to the next year. Luna: Or use tax-loss harvesting to offset some of those gains. If you have a losing position, you can sell it to realize a loss, which reduces your net investment income for NIIT purposes. Lucas: And don't forget about the wash sale rule. If you buy back the same security within thirty days, the loss is disallowed. So you have to be diligent about that. Luna: So to wrap up: the NIIT is a 3.8 percent surtax on investment income for high-income taxpayers. The thresholds are not indexed for inflation. Early retirees need to plan around it, especially if they're doing Roth conversions or have side income. And strategies like managing MAGI, using municipal bonds, and tax-loss harvesting can help. Lucas: That's a solid summary. And the big picture is: don't let a small tax surprise derail your carefully planned withdrawal strategy. A few hours of proactive planning can save you thousands over your retirement. Next episode, we'll talk about another stealth cost — the Medicare income-related monthly adjustment amount, or IRMAA, which can also catch early retirees off guard. Luna: Looking forward to it. Until then, keep your eyes on those tax thresholds.
