The Backdoor Roth IRA: A Legal Workaround for High Earners
If you’ve already maxed out your 401(k) and other tax-deferred accounts, the next question is usually where to put the rest. For a lot of high earners, the answer they skip over is the Roth IRA — skipped because they assume they earn too much to use one. On paper, they’re right. But there’s a legal path around the income limits that lets you put money somewhere it can grow tax-free and come out tax-free in retirement, even if a direct Roth contribution is off the table.
It’s called a backdoor Roth IRA, and the “backdoor” part sounds shadier than it is. It’s simply a conversion the IRS allows: you put money into a traditional IRA, which has no income limit, and then convert it to a Roth. Before you decide whether it’s worth doing, it helps to understand what it actually is and when it makes sense.
Why a Roth is worth the trouble
The appeal of a Roth comes down to when you pay the tax. You fund it with money you’ve already paid taxes on, so as long as your withdrawals are qualified, nothing more is owed when you take it out — not on the contributions, and not on decades of growth. Money that grows and comes out entirely tax-free is rare, and that’s the whole draw.
There’s a second advantage that tends to matter more the longer you’re retired: a Roth IRA isn’t subject to required minimum distributions. That’s not just a convenience. It gives you real control over your taxable income in retirement, which lets you keep that income under the thresholds that would otherwise start taxing your Social Security benefits or trigger the Medicare Part B and Part D surcharges. Keeping income off the books in the right years is one of the quieter ways a Roth earns its keep.
What a backdoor Roth actually is
A backdoor Roth IRA isn’t a special type of account. It’s a two-step move: you make a nondeductible contribution to a traditional IRA, then convert that money to a Roth. Traditional IRAs don’t carry income limits, so this gives high earners who are shut out of direct Roth contributions a completely legal way to get money into one.
Here’s why the workaround exists. The IRS sets the Roth income thresholds and adjusts them for inflation each year. For 2026, your ability to contribute directly to a Roth starts phasing out once your modified adjusted gross income (MAGI) reaches $153,000 if you’re single, or $242,000 if you’re married filing jointly. Once MAGI hits $168,000 (single) or $252,000 (joint), direct contributions are off the table entirely. The traditional IRA has no such ceiling — which is exactly what makes the conversion work.
How the conversion works
The mechanics are simpler than the name suggests. You open a traditional IRA, make a nondeductible contribution up to the 2026 limit of $7,500 (or $8,600 if you’re 50 or older), and convert it to a Roth right away. Because you funded it with after-tax dollars, the contribution itself converts without a new tax bill.
The timing matters, though. If you let the money sit in the traditional IRA and it grows before you convert, you’ll owe tax on that growth when you make the move. Converting promptly keeps things clean.
The part that trips people up
Where a backdoor Roth gets complicated is when you already have a traditional IRA in the picture — one you’ve funded for years, or watched grow, or deducted contributions on, or all three. The IRS won’t let you cherry-pick only your nondeductible contributions to convert. It looks at all of your traditional IRA money together and taxes the conversion proportionally. If most of your balance is pretax, a conversion you assumed would be tax-free can come with a bill you didn’t see coming. This is the single biggest reason to run the numbers before you act.
There’s a related change worth knowing about too, even though it applies to workplace plans rather than IRAs. Starting January 1, 2026, if you earned more than $150,000 in FICA wages last year from the employer that sponsors your 401(k) or 403(b), your age-50 catch-up contributions now have to go in on a Roth (after-tax) basis rather than pretax.
The tradeoffs
No strategy comes without strings, and a backdoor Roth has a couple. You can generally pull out your direct contributions anytime without tax, but money that arrives by conversion usually has to sit for five years before you can touch it without a 10% early-withdrawal penalty, if you’re under 59½. And to take out the account’s earnings completely free of tax and penalty, you need to be at least 59½ and have had a Roth open for at least five years.
There’s also the question of whether the math works in your favor at all. The Roth bet is that you’re better off paying the tax now than later. If your tax rate in retirement turns out to be much lower than it is today, paying up front doesn’t help you nearly as much as it helps someone whose rate is headed higher. Who you are matters as much as what the strategy does.
The bottom line
Used correctly, a backdoor Roth IRA can do something most retirement accounts can’t: build a pool of money that grows and comes out entirely tax-free. But “used correctly” is carrying real weight in that sentence. The pro-rata rule, the five-year clocks, and your own future tax bracket all change the answer. Before you convert anything, sit down with a CPA or financial advisor, run your specific numbers, and make sure the move actually does what you’re hoping it will.This work is powered by Advisor I/O under the Terms of Service and may be a derivative of the original.
