If you timely filed your 2025 federal return without fixing a $500 IRA excess, IRS instructions allow a correction within six months after the return’s due date, excluding extensions. For the ordinary 2025 filing calendar, that date is October 15, 2026. But withdrawing $500 by then does not automatically make the tax zero: the withdrawal, any related earnings, amended-return requirements, and your full contribution history matter.
When does the October 15, 2026 deadline apply?
This deadline concerns a 2025 excess contribution corrected in 2026. The IRS generally sets April 15, 2026 as the deadline for making 2025 IRA contributions. For someone who timely filed a return without withdrawing the excess, the 2025 Instructions for Form 5329 provide a separate six-month correction period measured from the return due date, excluding extensions. Six months after April 15 is October 15, 2026.
The IRS describes the rule this way: “If you timely filed your return without withdrawing the excess contributions, you can still make the withdrawal no later than 6 months after the due date of your tax return, excluding extensions.” IRS Instructions for Form 5329 (2025).
This is not a universal October 15 deadline for every tax year or filing situation. Special filing deadlines or a different tax year can change the relevant date; check the instructions for the year involved.
What does the 6% IRA excise tax mean?
The 6% is an annual excise tax on applicable excess IRA contributions that remain uncorrected. It can apply in each year the excess remains, subject to an IRS cap based on the combined year-end value of the relevant IRAs. It is not simply a one-time fee for making an excess contribution.
In its example for 2025, the IRS calculates a $30 additional tax on a $500 excess contribution: $500 × 6%. The actual calculation depends on the applicable rules and account values. The tax is reported on Form 5329; see IRS Publication 590-A (2025) and About Form 5329.

How to use the six-month correction procedure
- Confirm the tax year and filing facts. Verify that the excess relates to 2025 and that you timely filed your return without withdrawing it. Check the applicable year’s instructions if you had a special filing deadline.
- Contact your IRA custodian to request the appropriate corrective withdrawal. Tell the custodian it is intended to correct an excess contribution, rather than simply requesting an ordinary distribution. Ask how the account’s earnings or losses affect the amount and reporting. Do not assume that withdrawing only the original $500 resolves every requirement.
- File an amended return with the required notation. The IRS says to enter “Filed pursuant to section 301.9100-2” at the top of the amended return. Report related earnings for the year and make any necessary changes, including to Form 5329. The IRS’s instruction is in its Instructions for Form 5329 (2025).
- Keep the custodian’s records and your amended-return documentation. These help establish what was withdrawn and how the corrective transaction and any earnings were reported.
Whether the earnings are taxable and how the distribution is reported depend on the transaction and the taxpayer’s facts. A corrective withdrawal is not interchangeable with an ordinary distribution, so follow the custodian’s and IRS’s applicable reporting guidance.
What if you have not filed yet, or the excess is from another year?
For a current-year excess, the IRS describes a different route: withdrawing it by the return due date, including extensions, may allow it to be treated as not contributed, subject to the applicable conditions and treatment of earnings. That is distinct from the six-month procedure for someone who timely filed without correcting the excess. Read the year-specific rules in Publication 590-A before choosing a correction.

If an excess from an earlier year remains, do not assume that withdrawing $500 now erases prior-year consequences or produces a zero tax bill. The amount still present, account values, account type, whether a deduction was claimed, earnings or losses, and any earlier excess can affect the result. Apply the instructions for each relevant tax year to the complete facts.
