If you make too much money to contribute to a Roth IRA, there's a legal workaround that has been quietly sitting in the tax code for years.
It's called the backdoor Roth IRA, and it lets high earners get money into a tax-free retirement account without breaking any IRS rules.
Here's the catch: it's not a single product you sign up for.
It's a two-step process, and one sloppy move can trigger a tax bill you weren't expecting.
You contribute to a traditional IRA — no income limit blocks you there — then convert that money into a Roth IRA.
Since you already paid taxes on the contribution, the conversion typically costs nothing extra, as long as you don't have other pre-tax IRA money sitting around.
That last part is where people get burned.
If you have an old 401(k) rolled into a traditional IRA, the IRS uses a pro-rata rule to calculate how much of your conversion is taxable.
A $7,000 conversion could suddenly come with a tax hit on a chunk of your existing balance.
The fix most advisors suggest is rolling any pre-tax IRA money into your current employer's 401(k) first.
That clears the deck so your conversion stays clean.
Not every workplace plan allows this, so it's worth a call to your HR department before you move a dollar.
For 2025, the IRA contribution limit is $7,000, or $8,000 if you're 50 or older.
That's the amount you can shuttle through the backdoor each year.
Married couples filing jointly can each do it, doubling the amount to $14,000 or $16,000 combined.
A Roth IRA grows tax-free, and withdrawals in retirement don't count as income.
That matters if you expect higher tax rates later, or if you want to avoid required minimum distributions that force withdrawals from traditional accounts starting at age 73.
The conversion itself has no income limit, but you'll owe income tax on any pre-tax dollars you convert.
And if you convert and then need the money back within five years, you could face penalties on the earnings portion.
Paperwork trips up plenty of do-it-yourselfers too.
You'll get a Form 1099-R for the conversion and need to report it on Form 8606 when you file.
Miss that step and the IRS may treat the whole thing as a taxable distribution.
Most major brokerages — Fidelity, Vanguard, Schwab — let you do both steps online in a few minutes.
The contribution usually needs to settle before you convert, which can take a day or two.
One more thing worth knowing: Congress has debated closing this loophole for years, and it survived the last big retirement law overhaul.
That doesn't mean it's permanent, but for now it remains a legitimate tool. **The bottom line:** The backdoor Roth is one of the few remaining breaks that rewards people who plan ahead rather than people who earn the most.
If you're maxing out your 401(k) and still have cash to invest, it's worth a conversation with a tax professional before year-end.
Final Thoughts
Just handle the pro-rata rule first, or the tax bill will find you.
