If you make too much money to contribute to a Roth IRA, you are not locked out of one forever.
There's a legal workaround that has been on the books for years, and it keeps quietly showing up in financial planning conversations โ especially in January, when people start thinking about last year's taxes.
The mechanics are simple on paper: you put money into a traditional IRA, then convert it to a Roth.
Because the contribution was made with after-tax dollars, the conversion itself typically doesn't trigger a tax bill.
The result is money growing tax-free in a Roth, even if your income is well past the cutoff.
The catch is that "simple on paper" is doing a lot of work in that sentence.
For 2025, you can only contribute the full amount to a Roth IRA if your modified adjusted gross income is under $150,000 for single filers or $236,000 for married couples filing jointly.
Those numbers phase out and disappear entirely above $165,000 and $246,000.
Traditional IRA contributions, meanwhile, are not income-limited โ but the deduction is, if you have a workplace plan.
That's the seam the backdoor strategy slips through.
If you have any money sitting in a traditional IRA on December 31 of the year you convert, the IRS treats all of it as one big pot and taxes the conversion proportionally.
Someone with $80,000 in a rollover IRA from an old job who tries to convert $7,000 could end up owing tax on most of it.
Financial planners often tell clients in that spot to check whether their current 401(k) will accept a rollover first, which clears the traditional IRA balance out of the way.
The conversion gets reported on Form 8606, and if you skip it, the IRS has no idea you already paid tax on that money.
Neither is a fun way to spend a spring afternoon.
It makes it something to run past a tax professional before you click "convert," particularly if your situation isn't a clean single traditional IRA with no other balances.
The other thing worth saying out loud: this is not a loophole that Congress forgot about.
Lawmakers have proposed closing it more than once.
But "so far" is doing real work there too.
For households already maxing out a 401(k) and looking for the next place to park retirement money, the backdoor Roth remains one of the few remaining tax-advantaged options.
Just go in with your eyes open about the pro-rata math.
The honest take: this strategy rewards people who read the fine print and punishes people who don't.
If your finances are simple, it's a genuinely useful tool.
