Form 5329 Exception Code 21: Corrective Distribution

Updated October 17, 2026. Quick answer: Exception code 21 is for a corrective distribution of an excess IRA contribution, with the earnings on it, made on or before the due date of the income tax return including extensions. You enter the amount on line 2 of Form 5329 and write 21 in the space provided.

What exception code 21 means

The instructions give the code: “Corrective distributions of the income on excess contributions distributed before the due date of the tax return (including extensions).”

They then explain the rule in more detail: “The 10% additional tax on early distributions does not apply to an IRA distribution made pursuant to the rules of section 408(d)(4), which consists of a contribution for that year and any earnings allocable to the contribution, as long as the distribution is made on or before the due date (including extensions) of the income tax return.”

They also add a caution about the earnings: “Any related IRA earnings withdrawn with excess IRA contributions are taxable.”

What Pub. 590-B says about the timing

Pub. 590-B describes the same rule in its early distribution discussion: “the 10% additional tax on early distributions will not apply to a corrective IRA distribution, which consists of an excess contribution (a contribution greater than the IRA contribution limit) and any earnings allocable to the excess contribution, as long as the corrective distribution is made on or before the due date (including extensions) of the income tax return.”

Its reminders page says “The income on the corrective distribution of excess contributions made on or after December 29, 2022, is no longer subject to the 10% additional tax on early distributions.”

Where this fits in Part I

The Part I list of items the extra tax does not reach includes “A distribution of certain excess IRA contributions”. The instructions for line 1 also address the earnings: the amount to report includes “earnings on withdrawn excess contributions to your IRAs included in income in 2025”. Pub. 575 states a general version of the rule: “It also doesn’t apply to corrective distributions of excess deferrals, excess contributions, or excess aggregate contributions”. Which of these applies to your account depends on whether it is an IRA or an employer plan; the code 21 wording is about IRAs.

After the due date

A different rule applies when the withdrawal comes late. Pub. 590-B says “Certain withdrawals of excess contributions after the due date of your return are also tax free and therefore not subject to the 10% additional tax.” It sends readers to a section in Pub. 590-A for that situation. The wording of code 21 is tied to the due date, so check which description fits your withdrawal. The Form 1099-R code for the excess contribution cases is explained on the box 7 codes page.

How to claim it

The line 2 instruction is “Enter on line 2 the amount that you can exclude.” Write 21 in the space provided. The other exceptions are compared on early withdrawal penalty exceptions.

How to enter it on line 2

The instructions for line 2 begin “Enter on line 2 the amount that you can exclude.” They continue “In the space provided, enter the applicable exception number”. The form’s own wording for line 2 reads “Enter the appropriate exception number from the instructions”. The earlier lines are covered on the Part I lines 1 to 4 page, and the other exceptions are compared on early withdrawal penalty exceptions. The whole form is mapped in Form 5329 explained.

Where it goes next

Line 2 feeds line 3. The form’s caption for line 3 reads “Amount subject to additional tax. Subtract line 2 from line 1”. Line 4 then reads “Additional tax. Enter 10% (0.10) of line 3.” The form continues “Include this amount on Schedule 2 (Form 1040), line 8”. The instructions say the same for a joint return: “Include the combined tax on Schedule 2 (Form 1040), line 8.” Schedule 2 is explained on the Schedule 2 page.

Edition and line numbers

This page reads the 2025 Form 5329 and its 2025 instructions, and the 2025-returns edition of the Publication where one is cited. These are the current files irs.gov served on 2026-10-17, and they are the forms for the tax year 2025 return, filed in 2026. Check the tax year printed on the form you are filling in and use the line numbers and exception numbers on that year’s form, because a different year’s form can number or word its lines differently.

Common mistakes

  • Withdrawing after the deadline and still using code 21. The rule requires the distribution to be made “on or before the due date (including extensions) of the income tax return.”
  • Forgetting the earnings. The instructions say “Any related IRA earnings withdrawn with excess IRA contributions are taxable.”
  • Using code 21 for a distribution that is not a corrective one. Pub. 590-B limits it to “a corrective IRA distribution, which consists of an excess contribution”
