Every January, a certain kind of personal finance article tells you to fund a "backdoor Roth IRA" before the tax year ends.
The pitch sounds like a cheat code: earn too much to contribute directly to a Roth?
No problem—just route the money through a traditional IRA first.
What the pitch usually skips is who this actually works for, what it costs to pull off, and how easily it can go sideways.
In 2024, you can put up to $7,000 into IRAs ($8,000 if you're 50 or older).
Direct Roth contributions phase out once your modified adjusted gross income passes $146,000 for singles or $230,000 for married couples filing jointly.
Above those thresholds, the backdoor move is the standard workaround: contribute to a traditional IRA (nondeductible, since you earn too much for the deduction), then convert it to a Roth.
You owe income tax only on the growth between contribution and conversion—often a few dollars.
Because the IRS doesn't officially bless it, and one nasty rule can wreck the math.
The pro-rata rule says that if you hold any pre-tax money in a traditional, SEP, or SIMPLE IRA as of December 31 of the conversion year, your conversion gets taxed proportionally across all of it.
A $7,000 conversion sitting next to a $93,000 rollover IRA means roughly 93% of your conversion is taxable.
That surprise can run into thousands of dollars—and plenty of people discover it the following April.
You need to file Form 8606 every year to track your nondeductible basis.
Skip it, and you may pay tax twice on the same money.
The mechanics of reporting a backdoor conversion are famously confusing; tax software handles it inconsistently, and preparers charge extra.
Congress has repeatedly floated closing the loophole—it survived the Build Back Better negotiations, but it stays on the menu of revenue-raising ideas, meaning the strategy has a political shelf life nobody can predict.
Brokerages and advisors love the backdoor Roth because it's a reason to open an account and keep assets parked with them.
The articles touting it rarely mention that you could instead max out a 401(k) at work, use a health savings account, or fund a taxable brokerage account and harvest losses—options with fewer moving parts.
The honest take: if you have no pre-tax IRA balances and a simple tax picture, the backdoor Roth is a legitimate, low-cost way to get tax-free growth.
If you have a rollover IRA from an old job, run the numbers carefully before converting—rolling that IRA into your current 401(k) first can clear the way, but not every plan allows it.
If you're unsure, pay a CPA for an hour rather than trusting a headline.
My take: this is a legitimate strategy dressed up as a secret.
It's not free money, and it isn't risk-free—it's a compliance exercise with real tripwires.
Final Thoughts
Before you chase it, ask who profits from your clicking, and whether your situation actually fits the playbook.
