Excess Roth IRA contribution: how to fix it and avoid the 6% tax

An excess Roth IRA contribution is any amount you put into a Roth IRA for a year that is more than you were allowed to contribute. The IRS charges a 6% excise tax on the excess for every year it stays in the account. You can usually avoid that tax completely by removing the excess, plus the earnings on it, or by recharacterizing it to a traditional IRA, before your tax return due date including extensions.

Excess contributions are common and usually easy to fix if you catch them in time. This guide explains how they happen, how the 6% tax works, the four ways to correct one, and how to report the fix. IRS rules and annual limits change, so check the current figures in IRS Publication 590-A before acting.

How excess Roth contributions happen

Most excess contributions come from one of a handful of mistakes:

• Income too high. Roth IRA eligibility phases out above certain modified adjusted gross income (MAGI) levels, which change each year. A bonus, a business profit or a capital gain late in the year can push you over the line after you have already contributed.
• Contributing more than the annual limit. The limit is a combined figure across all your traditional and Roth IRAs, not a separate allowance for each. Contributing the maximum to both is an excess.
• Contributing more than your compensation. You cannot contribute more than your taxable compensation for the year. A retiree with no earned income, or a student with a small part-time wage, can easily exceed it. A spousal IRA may let a non-working spouse contribute based on the other spouse's income.
• Ineligible rollovers. Money that cannot be rolled over, such as a required minimum distribution or a second IRA-to-IRA rollover within 12 months, becomes a regular contribution once deposited, and is often an excess.
• Contributions to an inherited IRA. You cannot add new money to an inherited Roth IRA.
• Catch-up contributions before you are eligible. The extra catch-up amount is only available from the year you turn 50.

How the 6% excise tax works

Under IRC §4973, an excess contribution that is still in a Roth IRA at the end of the tax year (after taking into account corrections made by the return due date) is subject to a 6% excise tax. The tax is limited to 6% of the combined value of your Roth IRAs at year end, so it can be less than 6% of the excess if the account has fallen in value.

The important feature is that it repeats. The 6% applies again for each later year the excess remains in the account. An excess that sits unnoticed for several years costs 6% for each of those years, on top of any interest and penalties for not filing the form.

The tax is reported in Part IV of Form 5329, which you attach to your Form 1040 or file on its own if you are not otherwise required to file. SECURE 2.0 also tied the statute of limitations for this excise tax to the filing of your regular income tax return, which helps people who never filed a Form 5329, but it is not a reason to leave an excess in place.

Option 1: withdraw the excess and its earnings before the deadline

This is the standard fix. You ask your IRA provider for a "removal of excess contribution" or "return of excess", and they distribute both the excess and the net income attributable to it (NIA).

• Deadline. The withdrawal must be made by the due date of your return for the year of the contribution, including extensions. If you filed on time without the fix, the Form 5329 instructions allow the correction up to six months after the original due date, excluding extensions, by filing an amended return marked "Filed pursuant to section 301.9100-2." For most calendar-year filers that works out to October 15 of the following year.
• Tax on the excess. The excess itself comes back to you tax-free, because Roth contributions were made with after-tax money.
• Tax on the earnings. The NIA is taxable as ordinary income for the year the contribution was made, not the year you withdraw it.
• 10% additional tax. SECURE 2.0 (section 333) removed the 10% early distribution tax on earnings returned with a timely corrective distribution of an excess IRA contribution, regardless of age. The Form 5329 instructions now handle this with an exception code for corrective distributions.

The provider normally calculates the NIA using the formula in Treasury Regulation §1.408-11: the excess multiplied by the change in the account's adjusted value over the period the excess was held, divided by the adjusted opening balance. If the account lost value, the NIA can be negative and you withdraw less than you put in.

Here is an illustration with assumed figures, not real data. You contributed $2,000 more than you were allowed, and the account grew 5% while it was invested. The NIA would be about $100, so you would withdraw roughly $2,100. The $2,000 is not taxed; the $100 is reported as income for the contribution year. Your provider's calculation, not this example, is what counts.

Option 2: recharacterize the excess as a traditional IRA contribution

Instead of withdrawing the money, you can ask the provider to recharacterize the contribution, together with its NIA, as a contribution to a traditional IRA. The deadline is the same: the due date of your return, including extensions.

The recharacterized amount is then treated as if it had been contributed to the traditional IRA in the first place. This works well when the problem was income, not the overall limit, because anyone with compensation can contribute to a traditional IRA, although the deduction may be limited if you or your spouse are covered by a workplace plan.

A non-deductible traditional contribution leaves you with after-tax basis, which you track on Form 8606. Some people then convert that amount to Roth, which is the mechanism behind a backdoor Roth IRA. If you hold other pre-tax IRA money, the pro rata rule will make part of any conversion taxable, so think it through before you assume the conversion is tax-free.

Recharacterization is not the same thing as undoing a Roth conversion. Since 2018, a Roth conversion can no longer be recharacterized back to a traditional IRA. Only regular annual contributions can be.

Option 3: apply the excess to next year's limit

If you miss the deadline, or simply prefer to leave the money invested, you can absorb the excess into a later year. You pay the 6% tax for the year of the excess, then reduce the following year's contribution so that the earlier excess is treated as that year's contribution. This only works if you are eligible to contribute to a Roth IRA in the later year, which is not the case if the original problem was income above the limit and your income stays high.

This route is sometimes used for small excesses where the 6% cost for one year is minor, and the paperwork of a withdrawal is not worth it. It is less suitable for large excesses or where eligibility in the following year is uncertain.

Option 4: withdraw the excess after the deadline

You can still remove the excess after the deadline. In that case you withdraw the excess amount only. Earnings do not have to come out with it. You owe the 6% for every year up to and including the last year the excess remained at year end, but the tax stops once the excess is gone. For a Roth IRA, the withdrawal is generally treated as a return of your contributions, which comes out first and tax-free under the Roth ordering rules.

Which option fits which situation

Situation	Usual fix
Income turned out above the Roth limit, caught before the deadline	Recharacterize to traditional IRA, or withdraw with NIA
Contributed more than the combined annual limit, caught in time	Withdraw excess with NIA
Contributed more than compensation	Withdraw excess with NIA
Small excess, eligible to contribute next year, deadline missed	Pay 6% once and apply to next year's limit
Excess found years later	Withdraw the excess now; file Form 5329 for each affected year

Reporting the fix on your tax return

• A timely withdrawal reports the NIA as income for the contribution year. You will receive a Form 1099-R, often in the following January, with a code that identifies it as a return of excess. If you have already filed, you may need to amend.
• A recharacterization is explained in a statement attached to your return, and any non-deductible traditional contribution goes on Form 8606.
• An uncorrected excess goes on Form 5329, Part IV, for every year it remains in the account.

Keep the provider's correspondence and NIA calculation with your tax records.

If you also rely on the Roth IRA 5-year rule for tax-free earnings, check with your provider which contribution started your clock, since a removed excess is treated as if it had never been contributed.

Frequently asked questions

What is the deadline to remove an excess Roth IRA contribution?

The due date of your tax return for the contribution year, including extensions. If you filed on time without correcting it, you generally have until six months after the original due date, which is October 15 for most people, provided you file an amended return as the Form 5329 instructions describe.

Do I pay the 10% early withdrawal penalty on the earnings?

Not if the excess and its earnings are removed in a timely corrective distribution. SECURE 2.0 removed the 10% additional tax on that earnings portion. The earnings are still taxable as ordinary income for the contribution year.

What if my Roth IRA lost money?

The net income attributable can be negative, in which case you withdraw less than the original excess. The 6% excise tax, if it applies, is also capped at 6% of the account's year-end value.

Can I just leave the excess in the account?

You can, but the 6% tax applies every year until the excess is removed or absorbed into a later year's limit. For anything but a very small amount, correcting it is usually cheaper.
