If you earn too much to contribute to a Roth IRA directly, there's a workaround that's been legal for over a decade and millions of Americans still ignore it.
It's called the backdoor Roth, and it lets high earners funnel money into tax-free growth without breaking IRS rules.
You contribute to a traditional IRA — no income limit applies there — then convert that balance to a Roth.
The IRS treats the conversion as taxable income only on money that hasn't been taxed yet.
Since you made the traditional contribution with after-tax dollars, the tax bill is usually close to zero.
The catch that trips people up is the pro-rata rule.
If you already hold a traditional IRA with pre-tax money, the IRS doesn't let you convert just the new contribution.
It looks at your combined balance and taxes the conversion proportionally.
Someone with $50,000 in a rollover IRA who adds $7,000 gets hit with a much bigger tax bill than expected.
The clean fix is to roll any pre-tax IRA money into your employer's 401(k) first.
Most plans accept this, and once your traditional IRA balance hits zero at year-end, the backdoor conversion stays nearly tax-free.
Miss that step and you could owe thousands. **The numbers that matter** For 2025, the IRA contribution limit is $7,000, or $8,000 if you're 50 or older.
A married couple both doing the maneuver can move $14,000 into Roth accounts per year — $16,000 if both are over 50.
Do that consistently for a decade and you've sheltered well over $100,000 in accounts that grow tax-free and come out tax-free in retirement.
The conversion step has no income limit, but the IRS looks at your traditional IRA balance as of December 31 of the conversion year.
That means you can't do the contribution in January and convert in March while a $40,000 rollover IRA sits in the background.
Fix the pre-tax balance before year-end or the math punishes you.
You'll file Form 8606 with your tax return to report the nondeductible contribution and the conversion.
Skip it and the IRS may treat your contribution as pre-tax, which creates a taxable event down the line.
TurboTax and most preparers handle it, but solo filers using free software need to check that the form actually got generated. **Watch for the new rules** Starting in 2024, the SECURE 2.0 Act killed required minimum distributions for Roth accounts in employer plans, and Roth IRAs never had them for the original owner.
That makes the backdoor strategy even more attractive for long-term savers who want to leave money to heirs.
Each conversion has its own five-year clock before you can withdraw the converted amount penalty-free.
If you're planning to touch the money soon, this isn't the right tool. **Bottom line** The backdoor Roth isn't a loophole — Congress knows about it and has left it alone.
For households earning above the Roth income limits, it's one of the few remaining ways to build tax-free retirement money.
Final Thoughts
Check your traditional IRA balance first, clear out any pre-tax dollars, and let a tax pro glance at your Form 8606.
