The IRS has updated the income thresholds that determine who can fund a Roth IRA, and the new numbers are catching savers off guard.
For 2025, single filers phase out between $150,000 and $165,000 of modified adjusted gross income.
Married couples filing jointly phase out between $236,000 and $246,000.
Those ceilings represent a meaningful jump from a year ago, when the single-filer range topped out at $161,000.
The adjustment follows the same inflation-indexing formula the agency applies to dozens of retirement provisions each year.
For households whose paychecks have crept upward, that shift can mean the difference between a fully funded Roth and a rejected contribution.
Married couples filing separately face the harshest rule of all.
Their phase-out range is just $0 to $10,000, meaning even modest income can wipe out eligibility entirely.
That quirk has tripped up plenty of taxpayers who assume joint filing rules apply across the board.
Why the income cap matters so much comes down to how Roth accounts work.
Contributions go in after taxes, but withdrawals in retirement come out tax-free, provided you're at least 59½ and the account has been open five years.
No required minimum distributions, either.
For anyone who expects higher tax rates later, that combination is hard to beat.
If your income lands inside a phase-out range, you don't lose the whole contribution.
The IRS lets you put in a reduced amount, calculated as a proportion of the $7,000 annual limit, or $8,000 for those 50 and older.
The math is less intimidating than it sounds, and most tax software handles it automatically.
For savers who blow past the limit entirely, the backdoor Roth remains the workaround of choice.
It involves contributing to a traditional IRA — where no income cap applies — then converting the balance to a Roth.
The catch is the pro-rata rule, which taxes the conversion based on how much pre-tax money sits in any traditional IRA you own.
Someone with a large rollover IRA from an old job can end up owing a surprising bill.
If you fund a Roth and later discover you exceeded the limit, the IRS charges 6% per year on the overage until you fix it.
The correction window typically runs until your tax filing deadline, so waiting until April to check your eligibility is a costly gamble.
Check your modified adjusted gross income before you contribute, not after.
Your MAGI isn't the same as your salary — it includes investment income, some deductions get added back, and it can shift if you sold assets or received a bonus.
A five-minute look at last year's return beats a penalty letter from the IRS. **The bottom line:** These annual limit bumps reward savers who pay attention and punish those who assume last year's rules still apply.
Final Thoughts
If you're anywhere near the threshold, verify your number before writing that check — the tax-free growth is worth the homework.
