A popular retirement maneuver that lets high earners stash money in a tax-free account is drawing fresh scrutiny, and the timing couldn't be worse for households already stretched thin by rising costs.
The strategy, known as the backdoor Roth IRA, works like this: you contribute to a traditional IRA, then convert it to a Roth.
Because the IRS doesn't impose income limits on conversions, people who earn too much to contribute directly to a Roth can still get money into one.
It sounds like a loophole because it largely is one.
Congress banned direct Roth contributions for high earners years ago, but left the conversion door open.
Lawmakers have periodically floated closing it, and every time the idea resurfaces, financial advisors field a wave of panicked calls.
Here's why this matters even if you're nowhere near the income threshold.
Retirement rules are shifting fast, and the same tax-advantaged accounts middle-class families rely on are increasingly part of the debate in Washington.
What starts as a rule aimed at the wealthy has a way of trickling down.
The mechanics are simple, but the traps are not.
If you hold a traditional IRA with pre-tax money in it, the IRS applies the "pro rata" rule.
That means you can't convert just your after-tax dollars.
Your taxable and non-taxable balances get blended, and you owe income tax on the pre-tax portion.
That single rule trips up thousands of filers every spring.
Someone contributes $7,000, converts it, assumes they owe nothing, and then gets a surprise tax bill because an old rollover IRA from a former job was sitting in the same pot.
The cleanest workaround is to move any pre-tax IRA money into a 401(k) first, if your employer plan allows it.
Then your traditional IRA holds only after-tax dollars, and the conversion becomes nearly tax-free.
Brokerages generally charge nothing to open an IRA, but conversion paperwork, tax software upgrades, and advisor time can add up.
For a $7,000 conversion, even a few hundred dollars in costs eats into the benefit.
Roth conversions have their own waiting period before you can withdraw converted funds penalty-free.
Miss it and you could owe taxes plus a 10% penalty, which defeats the entire purpose.
For younger savers, the math still looks decent if you expect higher tax rates later.
For someone in their late 50s eyeing retirement in a few years, converting a large sum at today's rates could push them into a higher bracket and undo the advantage.
Many people who could use this strategy don't, because it sounds complicated and their tax preparer never mentions it.
Meanwhile, those who do use it often do so without checking whether a plain taxable brokerage account would serve them better.
Our take: the backdoor Roth is a legitimate tool, not a magic trick, and it rewards people who read the fine print.
If your income is climbing and you've maxed out your 401(k), it's worth a conversation with a tax professional before year-end.

Just don't expect the door to stay open forever.
