The Roth IRA remains one of the most flexible retirement accounts available to American workers, largely because withdrawals in retirement are tax-free.
But that perk comes with a catch that trips up higher earners every year: income limits that can quietly disqualify you from contributing.
For 2025, the income phase-out ranges shifted upward, giving some savers a bit more room.
Single filers can make a full contribution if their modified adjusted gross income stays at or below $150,000, with the ability phasing out completely at $165,000.
Married couples filing jointly get a range of $236,000 to $246,000.
Those numbers matter because they determine whether you can put money in at all.
Fall inside the phase-out window and you can only contribute a reduced amount.
Exceed the top of the range and the IRS says no direct contributions, period.
The contribution cap itself stayed at $7,000 for those under 50, with a $1,000 catch-up for anyone 50 and older.
That means a couple both over 50 could theoretically shelter $16,000 in a single year, provided their income keeps them under the limit.
Your "income" for Roth purposes isn't your salary alone.
It's modified adjusted gross income, which can include bonuses, investment gains, and certain deductions added back.
A year with a big capital gain from selling a stock or a house can push you over the line even if your paycheck didn't change.
The limit applies to the year you earn the money, not the year you file your taxes.
If you contribute in January based on last year's income and then get a raise, you may owe a penalty unless you correct it before the filing deadline.
The workaround most advisors point to is the backdoor Roth.
You contribute to a traditional IRA, which has no income limit, then convert it to a Roth.
It's legal, but it comes with paperwork and a pro-rata rule that can create an unexpected tax bill if you hold other traditional IRA money.
If you've already over-contributed, the fix is to withdraw the excess plus any earnings before the tax deadline.
Miss that window and you face a 6% excise tax for every year the money stays in.
The takeaway: check your MAGI before you fund, not after.
A quick look at last year's tax return plus a rough estimate of this year's income can save you a headache come April. **Our take:** The Roth income limits are a rare case where the rules are clear but easy to ignore until it's too late.
Final Thoughts
If you're anywhere near the threshold, run the numbers before you write the check, because the IRS won't call to warn you.
