If you've been faithfully funneling money into a Roth IRA, there's a number you need to check before you file your taxes: your modified adjusted gross income.
The IRS sets income limits that determine who can contribute to a Roth IRA, and crossing them can trigger penalties you probably didn't see coming.
For 2024, single filers can contribute the full amount if their MAGI stays under $146,000.
Married couples filing jointly get more room, with the full contribution allowed under $230,000 and no eligibility once income hits $240,000.
Those thresholds shift slightly each year, so what worked last tax season might not apply now.
A raise, a bonus, or a side gig that pushed your income over the line could quietly disqualify you.
If you already maxed out your Roth IRA and then discover you exceeded the limit, that excess contribution gets hit with a 6% tax for every year it stays in the account.
The IRS doesn't waive this because you didn't notice.
The fix involves removing the excess plus any earnings before your tax filing deadline.
Miss that window and the penalty keeps compounding.
Some people catch this years later and owe thousands.
There's a workaround many investors overlook: the backdoor Roth.
You contribute to a traditional IRA, then convert it to a Roth.
Income limits don't apply to conversions, though the pro-rata rule can complicate things if you already hold pre-tax IRA money.
Another option is simply contributing less.
If you're in the phase-out range, the IRS provides a worksheet to calculate your reduced limit.
Contributing the wrong amount is worse than contributing nothing.
Self-employed workers and freelancers need to watch this closely.
A strong year can push MAGI past the threshold fast, and unlike W-2 employees, nobody's withholding is tracking it for you.
Roth conversions can spike your taxable income, which affects Medicare premiums and Social Security taxation down the line.
The ripple effects go beyond just the IRA itself.
If you're unsure where you land, check your prior-year tax return or ask your accountant before contributing.
The contribution deadline for 2024 is April 15, 2025, so there's still time to adjust. **Our take:** The Roth IRA is one of the best retirement tools available, but the income limits are a trap for anyone whose earnings fluctuate.
Final Thoughts
Check your MAGI before you contribute, not after — the 6% penalty is a steep price for a paperwork oversight.
