If you have been faithfully funneling money into a Roth IRA every January, there is a number you need to check before you contribute another dollar.
The IRS adjusts the income limits that determine who can fund a Roth IRA, and those thresholds shift almost every year.
Cross the line and you may owe a penalty tax on money you thought was growing tax-free.
The Roth IRA is appealing for a simple reason: you pay taxes now, and withdrawals in retirement come out tax-free.
The government only lets you use it if your income falls below a certain ceiling, and the ceiling depends on whether you are single or married filing jointly.
Go over the top of the range and your allowed contribution drops to zero.
For the most recent tax year, single filers phase out between $146,000 and $161,000 of modified adjusted gross income, while married couples filing jointly phase out between $230,000 and $240,000.
Those ranges have climbed steadily, but so have salaries in many industries.
A raise, a bonus, or a side hustle that pushes you past the threshold can quietly disqualify you.
Your "modified adjusted gross income" is not the same as the number on your W-2.
It adds back certain deductions, like student loan interest and foreign earned income exclusions.
If you are close to the limit, you need to run the real calculation, not eyeball it.
Contributing when you were not eligible triggers a 6% excise tax on the excess amount for every year it stays in the account.
If you earn too much for a direct Roth contribution, you still have options.
Many people use a "backdoor Roth," which means contributing to a traditional IRA and then converting it.
The catch is the pro-rata rule: if you already hold a traditional IRA with pre-tax money, the conversion gets messier and can create a bigger tax bill.
Talk to a tax professional before trying this on your own.
If your income changes during the year because of a year-end bonus or a new job, you might not discover you crossed the limit until you file your taxes months later.
By then, the contribution is already sitting in the account.
You can fix it by withdrawing the excess plus any earnings before the tax deadline, but it takes paperwork and can cost you.
The practical move is to check your projected income in the fall, not in April.
If you are near the edge, you can reduce your contribution, wait until you know your final numbers, or use the backdoor route with guidance.
The limits exist, but so do legal ways around them.
My take: the Roth IRA is still one of the best deals in the tax code, but it rewards planning over autopilot.
Spend ten minutes with last year's return and a calculator before you fund this year's account.

That small check can save you a penalty and a headache you did not see coming.
