What Happens If You Contribute Too Much to an IRA?

If you contribute too much to an IRA, the IRS charges a 6% excise tax on the excess amount, and that penalty repeats every year the overage stays in the account. The good news: if you withdraw the excess (plus any earnings it generated) or recharacterize it by your tax-filing deadline, the penalty disappears entirely. The correction method you pick and how quickly you act decide whether you owe anything at all.

How to Tell If You Actually Over-Contributed

An excess IRA contribution is any amount deposited above the lower of two ceilings: the annual dollar limit or your taxable compensation for the year. For 2026, the dollar limit is $7,500 if you’re under 50 and $8,600 if you’re 50 or older, reflecting a $1,100 catch-up that now adjusts for inflation under the SECURE 2.0 Act.¹

The earned-income ceiling catches people off guard more often than the dollar cap. If you earned $5,000 in taxable compensation, the most you can contribute is $5,000, no matter what the statutory limit says. Taxable compensation includes wages, salaries, commissions, tips, bonuses, and net self-employment income.²

The limit also applies across all your IRAs combined. Put $5,000 into a Traditional IRA and $4,000 into a Roth in the same year, and you’ve contributed $9,000 total. That’s $1,500 over the 2026 limit for someone under 50, and the excess exists regardless of which account it landed in.³

The Roth Income Trap

Even a contribution well under the dollar cap can become an excess if your income exceeds the Roth eligibility thresholds. This is one of the most common ways people over-contribute by accident, because final income often isn’t known until tax time. For 2026, the MAGI phase-out ranges are:¹

Single or head of household: $153,000 to $168,000. At or above $168,000, no Roth contribution is permitted.
Married filing jointly: $242,000 to $252,000. At or above $252,000, no Roth contribution.
Married filing separately (living with spouse): $0 to $10,000. This narrow band effectively shuts most such filers out of the Roth.

Inside the phase-out range, you’re allowed a reduced contribution. Anything above that reduced amount is an excess subject to the 6% penalty unless corrected.

The 6% Penalty and How It Adds Up

The excise tax is 6% of the excess amount still in the account as of December 31.⁴ It hits every year the excess remains. A $2,000 overage left untouched for three years produces $120 per year, or $360 total.

There’s a ceiling: the 6% for any given year cannot exceed 6% of your combined IRA balance at year-end.³ For most people with an established balance, this cap doesn’t come into play. If you opened a new IRA, contributed $500 over the limit, and the account dropped to $400 by year’s end, the penalty would be capped at $24 rather than $30.

The 6% applies only to the excess itself, not to your whole balance and not to what the excess earned. Those earnings have their own treatment, which matters when you take the fastest fix.

Fix It Before the Tax Deadline: Withdraw the Excess

The cleanest correction is to pull the excess out of the account before your tax-filing deadline, including extensions. For a 2026 contribution, that means April 15, 2027, or October 15, 2027, if you file an extension. A withdrawal by that date eliminates the 6% penalty for that year entirely.⁵

You can’t just take out the dollar amount you over-contributed. You also have to withdraw the net income attributable (NIA) to that excess: whatever it earned or lost during the time it sat in the account. Your IRA custodian calculates the NIA using a formula based on the change in your account’s value.⁶

The excess principal comes back to you tax-free. The NIA is taxable as ordinary income for the year the original contribution was made. A recent change helps younger savers: under Section 333 of the SECURE 2.0 Act, effective December 29, 2022, the NIA on a timely correction is exempt from the 10% early-distribution penalty even if you’re under 59½.⁷ Before that change, the 10% would have stacked on top of the income tax.

If the excess lost money in the account, the NIA is negative. You withdraw less than you contributed, and you owe no tax on the negative NIA.⁵

The Six-Month Grace Window

Filed already and then realized you over-contributed? You still have room. You can withdraw the excess and NIA within six months of your original filing deadline (not counting extensions). For a return due April 15, 2027, that runs through October 15, 2027. File an amended return with “Filed pursuant to section 301.9100-2” written at the top, and the IRS treats the correction as timely.⁵

Miss that window, and the 6% for each year the excess sat in the account through December 31 has locked in. You can still pull the money out to stop the penalty going forward, but the past years are owed.

Recharacterize a Roth Contribution as Traditional

Recharacterization moves the contribution from one type of IRA to the other rather than pulling it out of the tax-advantaged system. You direct your custodian to transfer the contribution and its NIA into the other IRA, and the IRS treats the money as if it had been deposited there from the start.⁸

The most common use: you contributed to a Roth, then found your income cleared the phase-out. Recharacterizing the contribution as Traditional fixes the problem because Traditional IRAs have no income cap on the contribution itself (only on whether you can deduct it). The transfer has to happen by your tax deadline including extensions.⁸

Because the money stays inside an IRA, recharacterization triggers no income tax and no early-distribution penalty. If the resulting Traditional contribution is nondeductible because you’re covered by a workplace plan and your income is too high for the deduction, you’ll need to track that basis on Form 8606.⁹ One boundary: employer contributions under a SEP or SIMPLE plan cannot be recharacterized.⁸

Absorb the Excess in a Future Year

If you’d rather leave the money alone, you can apply the excess against a future year’s contribution room. You pay the 6% penalty for each year the excess is present as of December 31, but the overage shrinks in any future year you contribute less than the maximum.

Say you over-contributed by $1,500 in 2026. If you contribute nothing in 2027, the full $1,500 absorbs and the excess is gone. If you contribute $6,000 in 2027 against a $7,500 limit, the leftover $1,500 of room absorbs the excess. Once it’s fully absorbed, the 6% stops.

This works best for small overages you can absorb quickly. For larger amounts, the cumulative 6% often costs more than just withdrawing and re-contributing in a later year. You still have to file Form 5329 for every year the excess existed.¹⁰

Forms You’ll Need to File

Form 5329

Form 5329 is where the 6% excise tax is calculated and reported. If you didn’t correct the excess by December 31 of the contribution year, file Form 5329 with your return for that year. Excess Traditional IRA contributions go in Part III; excess Roth contributions go in Part IV.¹⁰ If the excess carries forward, file a new Form 5329 each year until it’s cleared.

If you withdrew the excess and NIA before the tax deadline (including extensions), you generally don’t need Form 5329 for that contribution because no penalty is owed. You do still report the taxable NIA as ordinary income for the contribution year.

One procedural point worth knowing: the statute of limitations on the 6% penalty generally doesn’t begin until you file Form 5329. Skip the form, and the IRS can potentially assess the penalty years later. Filing it, even when you believe the excess has been corrected, starts the clock.

Form 8606

If your fix leaves you with a nondeductible Traditional IRA contribution, whether through recharacterization or by leaving the money in as nondeductible, file Form 8606 to record the basis. This form tracks the after-tax money in your Traditional IRAs, which matters for future distributions and Roth conversions.⁹ Skip it and you risk double taxation later, because the IRS will treat a distribution as fully taxable if no basis is on record.¹¹
