If you make too much money to contribute to a Roth IRA, you are not out of luck.
A workaround called the backdoor Roth IRA has been around for years, and it is getting fresh attention as income limits stay frozen and more savers bump into them.
Here is the plain-English version of how it works, who it fits, and the traps that can trip you up.
The IRS caps who can put money directly into a Roth IRA.
For 2025, single filers phase out between $150,000 and $165,000 of modified adjusted gross income, while married couples filing jointly phase out between $236,000 and $246,000.
Earn above those ceilings and a direct Roth contribution is off the table.
You contribute to a traditional IRA — no income limit applies to that move — then convert that money to a Roth.
You pay income tax on any pre-tax dollars you convert, but if you are starting fresh with after-tax money and no existing traditional IRA balance, the tax bill is often close to zero.
Roth accounts grow tax-free, and qualified withdrawals in retirement come out tax-free too.
No required minimum distributions during your lifetime, which gives you flexibility that a traditional IRA does not.
The catch that snags the most people is the "pro-rata rule." If you already hold pre-tax money in a traditional IRA, SEP IRA, or SIMPLE IRA, the IRS looks at all of your balances together when you convert.
That means a chunk of your conversion becomes taxable, even if you only converted new after-tax dollars.
If your workplace 401(k) accepts rollovers, you can move your pre-tax IRA money into the 401(k) first.
That clears the deck so the pro-rata rule does not bite you.
Some advisors suggest making the traditional IRA contribution and doing the conversion in the same calendar year to keep the paperwork clean.
The IRS also treats conversions as happening on a first-in, first-out basis, so leftover balances can create surprise taxes.
One more detail: the "step transaction" doctrine worries some filers who convert too quickly.
In practice, the IRS has not cracked down on same-day or next-day conversions, but a short waiting period is a common precaution.
The annual contribution limit for IRAs in 2025 is $7,000, or $8,000 if you are 50 or older — the same for traditional and Roth.
That is the most you can move through the backdoor in a single year.
There is no income limit on conversions, and no cap on how much you can convert in one shot.
You could, in theory, convert a large traditional IRA balance all at once, though that usually triggers a big tax bill.
High earners who expect to be in a higher tax bracket later tend to like this strategy.
If you think tax rates will rise, paying tax now at a known rate to get tax-free growth later can pencil out.
If you are in a high-tax state now and plan to retire somewhere with no income tax, the math can flip.
And anyone with a large pre-tax IRA balance should run the numbers before converting.
The safest move is to talk to a tax professional who can look at your full picture.
A few hundred dollars of advice can save thousands in surprise taxes.
My take: the backdoor Roth is a legitimate, well-worn tool — not a loophole that will get you audited.
But it rewards people who plan ahead and punishes anyone who converts blindly.
Final Thoughts
Do the paperwork carefully, clear out pre-tax IRA balances first, and treat the tax bill as part of the cost of buying decades of tax-free growth.
