IRA Over-Contribution: 6% Penalty, Withdrawals, and Form 5329

An IRA over-contribution penalty is a 6% excise tax the IRS charges on any amount you put into a Traditional or Roth IRA above the annual limit, and it applies for every year the excess stays in the account.¹ The penalty is avoidable. If you pull the excess out (or recharacterize it) before your tax filing deadline for the year you contributed, including extensions, you owe no excise tax at all.² Miss that window and the 6% clock starts, and it keeps running every year until you fix the excess.

How to Know You Over-Contributed

For 2026, the combined cap across all your Traditional and Roth IRAs is $7,500, or $8,600 if you’re 50 or older.³ The limit is aggregate, not per account. Three IRAs receiving $3,000 each is a $1,500 excess.

You also can’t contribute more than your taxable compensation for the year. If you earned $4,000, that’s your ceiling regardless of the statutory limit.⁴ Compensation means wages, salaries, commissions, tips, bonuses, and net self-employment income. Rental income, dividends, pension payments, and deferred compensation don’t count.⁵ The exception: on a joint return, a non-earning spouse can contribute up to the full limit as long as the couple’s combined contributions don’t exceed the joint compensation reported.⁶

Roth Income Phase-Outs

Roth IRAs add income limits on top of the dollar cap. For 2026, your allowable Roth contribution phases out at these modified adjusted gross income (MAGI) ranges:³

Single or head of household: $153,000 to $168,000
Married filing jointly: $242,000 to $252,000
Married filing separately: $0 to $10,000

Inside those ranges, your allowable contribution shrinks. Above the top of the range, you can’t contribute directly to a Roth at all. A Roth contribution made when your income is over the limit is an excess contribution even if the dollar amount is under $7,500. This is one of the most common ways people trip into the penalty without realizing it.

Rollover Traps

Failed rollovers create excess contributions too. If you take a distribution from one IRA intending to roll it into another, you have 60 days to complete the transfer. Miss the window and the money in the receiving IRA can be treated as an excess contribution, on top of the original distribution becoming taxable. You’re also limited to one indirect IRA-to-IRA rollover in any 12-month period, and a second rollover inside that window becomes an excess.⁶

How the 6% Penalty Adds Up

The excise tax is calculated on the excess amount still in the account at year-end. Contribute $2,000 too much and leave it there for three years, and you owe $120 for each of those years, $360 total. The penalty is capped at 6% of the combined value of all your IRAs at year-end, but that ceiling only matters if your account balances are unusually small relative to the excess.⁷

The tax keeps compounding annually until the excess comes out (or gets absorbed into a future year’s limit). Small amounts add up when they sit for a decade.

Fix It Before Your Tax Deadline: Withdraw the Excess

The cleanest correction is a withdrawal before your tax filing due date for the contribution year, including extensions, which pushes the deadline to October 15.² A timely withdrawal wipes out the 6% penalty completely.

You can’t just pull the original dollar amount, though. The withdrawal has to include any net income attributable (NIA) to the excess during the time it was in the account. Your IRA custodian runs the calculation. It measures how much your IRA gained or lost during that period and assigns a proportional share to the excess.⁸ If the account lost money over that stretch, the NIA can be negative, meaning you withdraw less than the excess.

What Gets Taxed

The excess contribution itself comes back tax-free because it was never deducted. The earnings portion is taxable income in the year you made the original contribution, not the year of the withdrawal.⁹ If you’re under 59½, the earnings are also subject to the 10% early distribution penalty unless a separate exception applies (disability, qualified education expenses, and so on).¹⁰ The excess amount itself doesn’t trigger the 10%.

Fix It Before Your Tax Deadline: Recharacterize

Recharacterization is the right tool when your excess came from choosing the wrong IRA type, most often a Roth contribution made when your income turned out too high. You direct your custodian to move the contribution (plus its NIA) from the Roth to a Traditional IRA, and the IRS treats it as if it had gone into the Traditional from the start.¹¹ Same deadline as a withdrawal, and same result: no 6% penalty.

One boundary. Recharacterization applies only to contributions, not conversions. The Tax Cuts and Jobs Act permanently removed the ability to recharacterize a Roth conversion back to a Traditional IRA, so if you converted too much, this option isn’t available.

Fixing an Excess After the Deadline

Once October 15 passes with the excess still in the account, you owe the 6% for that year and lose the clean correction. You have two ways to stop the bleeding, but neither undoes what you already owe.

Withdraw It Late

You can withdraw the excess at any point. Doing so stops the penalty from accruing in future years, but you still owe 6% for every year the excess sat in the account through December 31.¹ A late withdrawal doesn’t require the NIA calculation. That’s only for timely corrections.

Absorb It Into Next Year’s Limit

If you’re eligible to contribute the following year, you can apply the excess against that year’s cap instead of pulling it out. Over-contributed by $1,500 in 2026? Contribute only $6,000 in new money in 2027 and the excess gets absorbed. The 6% stops accruing after the year of absorption, but you still owe it for every prior year the excess was there.² This is usually the right call when the excess is small and you planned to contribute again anyway.

Reporting on Form 5329

You report excess contributions and calculate the 6% excise tax on Form 5329.¹² It normally attaches to your Form 1040. If you’ve already filed or don’t otherwise need to file a return, you can submit Form 5329 by itself by the regular filing deadline, on paper with your signature and address.¹³

If you took a corrective distribution, your custodian issues a Form 1099-R. Those figures flow into Form 5329 and your return.

Why Filing Form 5329 Matters Even When You Owe Nothing

Filing Form 5329 changes how long the IRS has to come after the penalty. When Form 5329 is filed for the excise tax (attached or standalone), the statute of limitations is three years from the filing date. Skip Form 5329 and rely on your regular 1040 alone, and the window stretches to six years.¹⁴ Filing the form even when you’ve corrected the excess and owe no penalty starts the shorter three-year clock and caps your exposure.

A Note on SEP IRAs

SEP IRA excess contributions work differently because the employer, not the employee, is usually the party at fault. Employer contributions over the limit must be distributed from the employee’s SEP IRA back to the employer, adjusted for earnings through the correction date, and the employer gets no deduction for the excess. If the error is caught outside an IRS audit, the employer may instead apply to the Voluntary Correction Program (VCP) and keep the excess in the SEP IRA by paying a sanction of at least 10% of the excess. Minor errors caused by a breakdown in existing procedures may qualify for the Self-Correction Program without a formal filing.¹⁵
