What Happens If You Over Contribute to a Roth IRA? Excess Contribution Fix 2026

An excess Roth IRA contribution triggers a 6% excise tax (IRC §4973) on the excess each year it remains in the account, reported on Form 5329. Three fixes: (1) take a corrective distribution (excess plus attributable earnings) by your tax-filing deadline including extensions; (2) recharacterize the excess to a traditional IRA if you'd qualify there; or (3) absorb it by reducing next year's contribution by the excess amount.

Quick Facts

warning6% excise tax under IRC §4973 applied to the excess each year it remains in the account. Compounds quickly if untreated.
infoForm 5329 reports the excise on your tax return. Even if you owe nothing, file Form 5329 to document the situation.
check_circleCorrective distribution before tax deadline (including extensions) avoids the 6% excise entirely. Must remove the excess + attributable earnings.
infoEarnings on the excess are taxable as ordinary income in the year the excess was made (not the year removed). Plus 10% penalty if you're under 59½.
warningDon't ignore it. The 6% applies for every year the excess sits — a $7,500 excess left for 5 years costs $2,250 in cumulative excise tax.

Common Causes of an Excess Contribution

Income above the phase-out. You contributed early in the year before knowing your final MAGI; year-end income exceeds $168,000 single / $252,000 MFJ for 2026.
Insufficient earned income. You contributed $7,500 but your W-2 wages or self-employment income totaled only $5,000 for the year. Per IRC §219(b)(5), contributions cannot exceed earned income.
Multiple-account aggregation oversight. $5,000 to one Roth IRA + $3,000 to another = $8,000, over the $7,500 cap.
Spousal IRA confusion. Working spouse's earned income wasn't enough to cover both spouses' contributions.
Reduced-contribution-formula error. MAGI inside the phase-out band ($153K-$168K single, $242K-$252K MFJ) reduces the allowed contribution; many readers contribute the full amount and discover the partial cap at tax-filing time.

Path 1: Corrective Distribution (Best Option)

If you catch the excess before your tax-filing deadline (April 15, or October 15 if you filed an extension), you can have the custodian process a corrective distribution. The custodian removes the excess contribution PLUS any attributable earnings on that excess. This avoids the 6% excise entirely.

Procedure:

Contact your custodian and request "return of excess contribution" — most have a dedicated form.
The custodian calculates the gain or loss attributable to the excess using adjusted opening and closing balances under Treas. Reg. §1.408-11.
Custodian distributes the excess + earnings to you, issues a Form 1099-R coded 8 (return of excess) or P (return of excess applicable to prior year).
Any earnings are taxable in the contribution year, even if removed later. No 10% early-distribution tax applies to earnings returned through a timely correction under SECURE 2.0 §333. This does not make the earnings income-tax-free.
Report the correction using your custodian's Form 1099-R and the applicable return instructions. Form 5329 may be needed to claim the exception or report an excess left uncorrected; see the IRS instructions, including exception 21.

Path 2: Recharacterize to Traditional IRA

If your excess Roth contribution was due to income above the phase-out, but you'd qualify for a traditional IRA contribution (no income limit), recharacterize the contribution. The custodian re-codes the contribution as having been made to a traditional IRA from inception. Per IRC §408A(d)(6), recharacterization of CONTRIBUTIONS (not conversions, post-TCJA) is still allowed.

Deadline: by the tax-filing due date including extensions. Custodian processes the trustee-to-trustee transfer of the contribution + attributable earnings to a traditional IRA. No tax due, no excise.

If you were under the workplace-plan-coverage threshold, the traditional IRA contribution may also be deductible. Note: if your goal was Roth treatment, you can subsequently do a Backdoor Roth (convert the recharacterized traditional contribution back to Roth) — but watch the pro-rata rule per IRC §408(d)(2).

Path 3: Absorb Into Next Year

A prior-year excess can be absorbed by unused contribution room in a later year under IRC §4973(f). You must actually be eligible for that year's Roth contribution, considering age, compensation, income and contributions to your other IRAs. Absorption does not erase excise tax already incurred in earlier years.

Worked example: assume you are under 50, eligible for the full $7,500 Roth allowance for 2026, and contribute $9,000 to your only IRA. The excess is $1,500. If you miss the timely-correction deadline, absorbing it in 2027 requires at least $1,500 of unused, otherwise-allowed 2027 contribution room.

To absorb all $1,500, keep new contributions within your applicable 2027 allowance minus $1,500, allowing for contributions to your other IRAs. No 2027 dollar limit is assumed here. If your unused allowance is smaller, only that smaller amount can be absorbed. Report the carryover and reduction on Form 5329.

Assuming your year-end Roth IRA value is at least $1,500, the 2026 excise is $1,500 × 6% = $90. Another year's tax can arise on an excess that remains; this is an annual charge, not compound interest. See the Form 5329 instructions, Part IV.

Frequently Asked Questions

How does the IRS find out about my excess contribution?

Your custodian reports IRA contributions to the IRS on Form 5498. The IRS can compare those reports with your return and other IRA contributions. An error does not guarantee a particular notice, and waiting for the IRS does not pause the correction deadline. Check your own eligibility and records promptly.

Can I just leave the excess and pay the 6% indefinitely?

Paying the tax does not fix the excess. A $7,500 excess can produce $450 of excise each year it remains, assuming the year-end Roth IRA value is at least that amount: $4,500 over 10 years before other charges. Separately, assessment deadlines do exist. Under IRC §6501(l)(4), an income-tax return can start the clock for IRA excise tax; the period is generally six years for §4973 when relying on that return, rather than the ordinary three-year period for a properly filed Form 5329. Filing requirements, fraud and the exception for property acquired below fair market value can change the analysis. Have a tax professional check older years; a closed assessment period does not create new contribution room.

What if my excess was due to a clerical custodian error?

Keep the records and ask the custodian to correct the transaction and any inaccurate tax forms. Do not assume the 6% excess-contribution tax will be waived just because the mistake was clerical. The reasonable-error waiver described in Form 5329 instructions, Part IX, concerns missed required distributions, not a general waiver of excess Roth contributions. A tax professional can help determine the correction deadline and what you need to report.

Does the corrective-distribution earnings calculation always work in my favor?

The adjustment follows the IRA's gain or loss during the calculation period. In a timely correction, a gain increases the amount returned and a loss reduces it; the correction can avoid the 6% excise. An excess left uncorrected follows separate annual excise-tax rules, including the year-end account-value cap. Ask your custodian to calculate the adjustment.
