You can no longer contribute to a Roth IRA once your modified adjusted gross income passes the ceiling for your filing status, once you stop having earned income, once you’ve hit the annual dollar cap, or once the tax filing deadline for that year has passed. For 2026, single filers lose eligibility completely at a MAGI of $168,000, and married couples filing jointly lose it at $252,000.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Each of these limits works differently, and getting one wrong can trigger a 6 percent excise tax that repeats every year the excess sits in the account.
Your Income Is Too High
Income is the most common reason people get shut out. The IRS uses MAGI ranges that first reduce and then eliminate your allowed contribution. For 2026:
- Single or head of household: the phase-out runs from $153,000 to $168,000. At $168,000 or above, no direct contribution is allowed.
- Married filing jointly: the phase-out runs from $242,000 to $252,000.
- Married filing separately, if you lived with your spouse at any point during the year: the phase-out runs from $0 to $10,000, which effectively bars almost everyone in this status.
Within a phase-out range, you can still contribute a reduced amount calculated proportionally to where your income sits in the band.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The married-filing-separately window of $0 to $10,000 does not adjust for inflation. A married person who lived apart from their spouse for the entire year and files separately is treated as single, so the wider $153,000 to $168,000 range applies.2Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs
How MAGI Differs From AGI
Your MAGI for Roth purposes starts with the adjusted gross income at the bottom of page 1 of Form 1040 and adds back several items. The common add-backs are your traditional IRA deduction, the student loan interest deduction, the foreign earned income exclusion, and any employer-provided adoption benefits you excluded from income.3Internal Revenue Service. Modified Adjusted Gross Income If your income is entirely domestic wages with none of those deductions, MAGI and AGI will match. Otherwise MAGI can be higher than you expect, which is enough to push you into or over a phase-out range.
You Have No Earned Income
Even if your MAGI is far below the limit, contributions require taxable compensation. Qualifying compensation includes wages, salaries, tips, bonuses, professional fees, self-employment income, nontaxable combat pay, and taxable alimony from pre-2019 divorce agreements.4Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs)
What does not count: rental income, interest, dividends, pension and annuity payments, deferred compensation, and Social Security benefits.4Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs) This is why retirees who live entirely on Social Security, a pension, or portfolio income cannot contribute, no matter how large the portfolio.
Earnings also cap your contribution from below. If you earned $3,000 in a year, your contribution limit for that year is $3,000, not the statutory maximum.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits
The Spousal Exception
A joint filer with no earnings of their own can still contribute if the working spouse has enough compensation to cover both accounts. Each spouse can contribute up to the full annual limit, provided the couple’s combined contributions do not exceed the total taxable compensation on the joint return.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits This is the Kay Bailey Hutchison Spousal IRA provision, and it still requires the couple’s MAGI to stay below the joint phase-out threshold.6eCFR. 26 CFR 1.408A-3 – Contributions to Roth IRAs
You’ve Hit the Annual Dollar Cap
Meeting the income and compensation tests still leaves the hard dollar cap. For 2026:
- Under age 50: $7,500
- Age 50 or older: $8,600, which is the base $7,500 plus a $1,100 catch-up
The cap covers your traditional and Roth IRA contributions combined, not each account separately.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Someone under 50 who puts $4,000 into a traditional IRA and $4,000 into a Roth in the same year is $500 over the limit, and the IRS treats that $500 as an excess contribution.
Age itself is not a cutoff. There is no upper age limit for Roth IRA contributions, and the pre-2020 age-70½ ceiling on traditional IRA contributions never applied to Roths.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits As long as you have qualifying earned income and stay under the MAGI ceiling, you can keep contributing at any age.
The Deadline Has Passed
You have until the tax filing deadline, typically April 15 of the following year, to contribute for a given tax year. For 2026, the window runs from January 1, 2026, through April 15, 2027.4Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs)
A filing extension does not extend the contribution deadline. Even if you have extra time to file, you cannot contribute after April 15.4Internal Revenue Service. Publication 590-A (2025), Contributions to Individual Retirement Arrangements (IRAs) Anything deposited afterward counts against the next tax year, assuming you’re still eligible then. Once the deadline passes for a given year, that year’s contribution room is gone for good.
A narrow exception applies if you live in a federally declared disaster area. The IRS can postpone the contribution deadline for up to one year, and disasters occurring after mid-2025 may also carry a mandatory 120-day postponement for affected taxpayers.7Internal Revenue Service. Publication 547 (2025), Casualties, Disasters, and Thefts
What Happens if You Contribute When You Can’t
Contributing more than you’re allowed, whether because your income turned out higher than you thought, you overshot the dollar cap, or you didn’t have enough earned income, triggers a 6 percent excise tax on the excess. The penalty is charged every year the excess remains in the account, not just the year you made the mistake.8Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities
Two ways to fix an excess contribution before the tax bites:
- Withdraw the excess plus any earnings it generated by the due date of your return, including extensions. The contribution is then treated as if it never happened. The earnings are taxable in the year of the contribution, and if you’re under 59½ they carry an additional 10 percent early-withdrawal penalty.9Internal Revenue Service. Instructions for Form 5329 (2025)
- Recharacterize the contribution as a traditional IRA contribution through a trustee-to-trustee transfer of the money and its earnings. This also must generally happen by the due date of your return, including extensions, and is reported on Form 8606 with an explanatory statement.10Internal Revenue Service. Instructions for Form 8606
If you’ve already filed without correcting the excess, you still have a window: you can withdraw it within six months of the original due date (not counting extensions), then file an amended return with “Filed pursuant to section 301.9100-2” written at the top.9Internal Revenue Service. Instructions for Form 5329 (2025) Miss that window and the 6 percent penalty applies for the year of the excess and every subsequent year until you either remove the money or absorb it into future years’ unused contribution room.
Blocked by Income? The Backdoor Route
If income is what shut you out, direct contributions aren’t the only way into a Roth. Federal law lets anyone convert a traditional IRA to a Roth IRA regardless of income.2Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs The backdoor strategy uses this: you make a non-deductible contribution to a traditional IRA, which has no income limit, and then convert that balance to a Roth. Both steps are reported on Form 8606.10Internal Revenue Service. Instructions for Form 8606
The conversion is clean when you don’t hold any other pre-tax IRA money. If you do hold pre-tax funds in any traditional, SEP, or SIMPLE IRA, the pro-rata rule treats every conversion dollar as a proportional mix of pre-tax and after-tax money across all your IRA balances, and you cannot isolate the after-tax portion to convert on its own.11Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans Failing to file Form 8606 when required carries a $50 penalty per missed filing, which the IRS may waive for reasonable cause.10Internal Revenue Service. Instructions for Form 8606
