If you make too much money to fund a Roth IRA directly, there's a legal workaround that millions of Americans have quietly used for years.
It's called a backdoor Roth IRA, and rising income limits mean more people are searching for it than ever.
Here's how it works, who it's for, and the trap that catches people every tax season.
The IRS caps who can contribute to a Roth IRA based on income.
For 2024, single filers phase out between $146,000 and $161,000, while married couples filing jointly phase out between $230,000 and $240,000.
Earn above those ceilings and the front door is closed.
The backdoor is simply two steps: contribute to a traditional IRA, then convert that money to a Roth.
Roth accounts grow tax-free, and qualified withdrawals in retirement come out tax-free too.
No required minimum distributions during your lifetime.
For high earners who expect higher taxes later, that combination is hard to beat.
A traditional IRA alone gives you a deduction now but taxes every dollar later.
There's one big catch, and it's called the pro-rata rule.
If you hold pre-tax money in any traditional IRA, the IRS doesn't let you convert just the new after-tax dollars.
It looks at your total IRA balance and taxes the conversion proportionally.
Someone with $90,000 in a rollover IRA and a fresh $7,000 contribution can't convert only the $7,000 tax-free.
The fix is straightforward for many people: roll existing pre-tax IRA money into a 401(k) before doing the conversion.
Not every workplace plan accepts incoming rollovers, so check first.
If your employer plan allows it, you can clear the deck and convert cleanly.
The mechanics are simpler than the name suggests.
Open a traditional IRA, contribute after-tax dollars, and invest them.
Then convert to a Roth IRA, usually through the same brokerage.
You'll report the contribution and conversion on IRS Form 8606 when you file.
Keep every statement, because brokerages issue a 1099-R for the conversion and the numbers don't always match cleanly.
The "step transaction" doctrine lets the IRS collapse related steps, but years of practice and IRS guidance have treated the two-step process as legitimate.
Some advisors still recommend waiting between contributing and converting, though many brokers process both in days.
Converting late in the year can leave you guessing at your tax bill, since the taxable amount depends on your year-end IRA balance.
A market rally in December can push more of your conversion into taxable territory.
Many advisors suggest converting early in the year or spreading conversions across months.
This isn't a loophole in the shady sense.
Congress has known about it for over a decade.
Lawmakers have proposed closing it, and those proposals keep resurfacing, which is one reason some savers act sooner rather than later.
If you're above the income limit and want Roth-style tax treatment, the backdoor is currently the standard path.
Our take: the backdoor Roth is one of the few remaining tax advantages high earners can use without a team of lawyers.
If you have pre-tax IRA money sitting around, run the pro-rata math before you convert, or you may owe more than you expect.
Done cleanly, it's a powerful long-term move.

Done carelessly, it's a surprise tax bill.
