Putting too much into an IRA is a common mistake, and the tax code punishes it in an unusually persistent way: a 6 percent excise tax that lands not once but every single year the excess stays in the account. The saving grace is a built-in escape hatch. A saver who pulls the excess contribution back out — along with whatever it earned — before a specific deadline erases the penalty entirely, as if the overcontribution never happened. The whole question is one of timing, and the clock runs on the tax-filing calendar.
How a contribution ends up over the line
An excess contribution is any amount deposited above what the rules allow, and there is more than one way to trip over the limit. The simplest is contributing more than the annual cap. For 2026 the IRA contribution limit rose to $7,500, with an extra $1,100 catch-up for savers 50 and older, bringing their ceiling to $8,600 — and anything deposited beyond that figure is excess by definition. The cap applies across all of a person’s traditional and Roth IRAs combined, so someone funding two accounts can breach it without any single deposit looking oversized.
The limit is not the only trap. A contribution can also become excess when a saver lacks enough earned income to support it, since IRA contributions must be backed by compensation, or when a high earner exceeds the income ceiling for a Roth IRA and contributes anyway. The IRS rules on contribution limits tie the allowable amount to both the annual cap and the saver’s income, so a contribution that looked fine in January can turn into an overcontribution once the year’s actual earnings are known. A failed rollover — money that misses the 60-day window to land back in a qualified account — can likewise be recharacterized as an excess contribution after the fact.
Because those figures are not always final until tax time, many excess contributions are discovered only while preparing a return. That timing is fortunate, because the same return deadline is what governs the cure, and the 2026 limits themselves were fixed by the IRS in its annual cost-of-living announcement.

The recurring penalty and the deadline that stops it
The 6 percent excise tax is what makes an ignored excess so costly. It is assessed on the excess amount for each year the money remains in the account, so a $1,000 overcontribution left in place is not a single $60 charge but $60 a year, compounding into a real drain the longer it sits. The tax is reported on Form 5329, the return the IRS uses to collect additional taxes on qualified plans and IRAs, and it keeps reappearing until the excess is removed or absorbed. The excise is capped at 6 percent of the account’s value at year-end, a ceiling that only matters when the account has lost money.
The clean fix is a corrective withdrawal made by the due date of the tax return for the year of the contribution, including extensions. A saver who takes out the excess amount plus the earnings attributable to it by that deadline avoids the 6 percent tax altogether. With an extension, the window generally runs into mid-October of the following year, giving even a late-discovered overcontribution time to be undone. A saver who already filed a timely return is still treated as meeting the deadline if the correction is made within six months and an amended return follows.
The earnings piece is where the correction gets technical. The withdrawal must include not just the extra dollars but the investment gain those dollars produced while in the account — the net income attributable, which the custodian calculates with an IRS formula that prorates the account’s overall gain or loss to the excess. That gain is treated as taxable income for the year the contribution was made, and for a saver under 59½ it can also draw the 10 percent early-distribution penalty. If the excess instead lost value, the amount removed is adjusted downward, and less comes out than went in. Getting the earnings calculation right is what makes the withdrawal a true correction rather than an ordinary distribution.
The options once the deadline slips
Missing the corrective-withdrawal window does not make the penalty permanent, but it changes the remedy. A saver who is past the deadline can still stop the tax from recurring by absorbing the excess into a later year’s contribution room — leaving the money in the account but under-contributing in a subsequent year so the prior excess counts against the new year’s limit. That approach ends the annual charge going forward, though it does not refund the 6 percent already owed for the years the excess was outstanding.
Another route is simply removing the excess after the deadline as a regular distribution, which halts future excise tax but can carry its own consequences, including ordinary income tax and, for younger savers, an early-withdrawal penalty on any taxable portion. After the deadline the earnings no longer have to come out — only the excess principal — but the 6 percent clock keeps running for every year the money lingers first. Neither late option is as clean as the timely corrective withdrawal, which is why catching the problem before the filing deadline matters so much.
The larger lesson is that an IRA overcontribution is a deadline problem disguised as a paperwork problem. The penalty is designed to keep charging until the account is brought back within the limits, so the cost of inaction rises every year while the cost of a prompt fix is essentially zero. For a saver who spots the excess during tax season — the moment income figures finally settle — the correction is straightforward and the penalty avoidable. For one who lets it ride, the same 6 percent returns each spring, quietly turning a bookkeeping slip into a recurring tax.
