The Roth IRA has a problem that millions of high earners know too well.
You can only contribute if your income falls under certain limits, and once you cross them, the door slams shut.
For 2024, single filers start losing eligibility at $146,000, and married couples filing jointly hit the phase-out at $230,000.
But there's a legal workaround that's been around since 2010, and it's becoming a staple of mainstream financial planning.
It's called the backdoor Roth IRA, and it lets people above the income limits get money into a Roth account anyway.
Here's how it works: you contribute to a traditional IRA, which has no income limits, then convert that money into a Roth IRA.
You pay taxes on any pre-tax dollars you convert, but if your contribution was made with after-tax money, the tax bill is usually zero or close to it.
The strategy gained fresh attention after the 2017 tax law.
Before then, converting a traditional IRA to a Roth triggered taxes on all pre-tax money in any of your IRAs, which made the backdoor messy for people with existing balances.
The new rules made it cleaner for many savers, though the pro-rata rule still trips people up.
If you hold any pre-tax money in a traditional, SEP, or SIMPLE IRA on December 31 of the conversion year, the IRS treats your conversion as a mix of pre-tax and after-tax dollars.
That means you can't convert just the after-tax portion tax-free.
You'll owe taxes on a proportional slice, and the math gets complicated fast.
If your employer offers a 401(k), one common fix is to roll your pre-tax IRA money into that plan before doing the conversion.
That clears out the pre-tax balance and lets the backdoor work as intended.
Not every workplace plan accepts rollovers, so it's worth checking first.
You open a traditional IRA, contribute up to the annual limit, and convert it to a Roth.
For 2024, the IRA contribution limit is $7,000, or $8,000 if you're 50 or older.
A married couple can each do this, doubling the amount moved into Roth accounts.
There's a paperwork wrinkle that catches first-timers.
You'll get a Form 1099-R for the conversion and need to file Form 8606 to report the after-tax basis.
Miss the 8606 and the IRS may assume the whole conversion was taxable, which can trigger a surprise bill.
Software usually handles this, but it's worth double-checking before you file.
One more thing left out of most headlines: a backdoor Roth isn't a separate account type.
It's just a traditional IRA and a Roth IRA, plus two transactions.
Nothing about the account itself changes, and the Roth still grows tax-free with tax-free withdrawals in retirement.
Some lawmakers have floated closing the backdoor, and proposals have appeared in various budget plans over the years.
For now, the strategy remains legal and widely recommended by financial professionals.
If your income is near or above the Roth limits, it's worth asking a tax professional whether this fits your situation.
The rules aren't complicated, but the details matter, and one wrong step can create a tax headache you'll spend months untangling.
The backdoor Roth isn't a loophole so much as a quirk of the tax code that Congress has known about for over a decade.
For savers who plan ahead and keep their paperwork clean, it's one of the more useful tools available.
Final Thoughts
Just don't try to wing it without understanding the pro-rata rule first.
