You can find Form 5329 for free on the IRS website at IRS.gov, either by searching “Form 5329” or going to the About Form 5329 page, which links to both the fillable PDF and the line-by-line instructions.1Internal Revenue Service. About Form 5329, Additional Taxes on Qualified Plans File it as an attachment to your Form 1040 for the current year, or mail it in as a standalone document if you are cleaning up a prior year or do not otherwise need to file a return.
Downloading the Right Version
Always pull the version that matches the tax year you are addressing. If you are correcting a missed required minimum distribution from 2024, use the 2024 form, not the current year’s version. The IRS keeps prior-year forms available on the same site.
Most tax preparation software already includes Form 5329 and generates it automatically when you enter an early distribution, an excess contribution, or a missed RMD during the interview. If that describes your situation, you likely will not need to download the PDF separately. If you are filing on paper or handling a prior year the software no longer covers, the PDF on IRS.gov is the source.
Two Ways to File It
How you file depends on whether Form 5329 is riding along with a regular return or going in on its own.
Attached to Your Form 1040
Most people file Form 5329 as part of their annual Form 1040. The additional tax calculated on the form flows to Schedule 2 (Form 1040), line 8, which then feeds into your total tax on the 1040.2Internal Revenue Service. Form 5329 – Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts With tax software, this transfer happens automatically.
When Form 5329 is attached to your 1040, the whole package can be e-filed. The payment deadline is the same as your regular return, typically April 15. An extension to file gives you more time to submit the paperwork but does not extend the deadline to pay. Interest and failure-to-pay penalties start accruing on any unpaid balance after April 15.3Internal Revenue Service.

As a Standalone Document
If you do not otherwise need to file a tax return for the year, or if you are correcting a prior-year issue such as a missed RMD or an old excess contribution that was never reported, you can file Form 5329 by itself.
A standalone Form 5329 cannot be e-filed. It must be mailed on paper.4Internal Revenue Service. Instructions for Form 5329 (2025) Write the tax year clearly at the top of the form, include your current mailing address on page 1, and sign and date page 3. Mail it to the same IRS address where you would send your Form 1040 for that year, which depends on your state of residence. The instructions contain a table with the correct mailing addresses. You can pay any additional tax electronically through IRS Direct Pay or EFTPS even when the form itself goes by mail.
When You Actually Need This Form
Form 5329 is for additional taxes on qualified plans and other tax-favored accounts. Three situations cover most filings.
Early distributions before age 59½. Withdrawing from an IRA, 401(k), or other qualified retirement plan before 59½ generally triggers a 10% additional tax on the taxable portion.5Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Even when an exception applies, you still need Form 5329 to claim it. If you skip the form, the IRS may automatically assess the 10% penalty based on the distribution code in box 7 of your 1099-R. One nuance: if that code is 2, 3, or 4, the exception is already built into the reporting and you generally do not need Form 5329 for that distribution. Code 1 means you must file Part I yourself to claim any exception.
Excess contributions. Contributing more than the annual limit to an IRA, HSA, Coverdell ESA, or Archer MSA triggers a 6% excise tax on the excess for every year it stays in the account.6Office of the Law Revision Counsel. 26 USC 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities The penalty is not a one-time hit; it recurs each year the excess is still there at year-end. To avoid it for a given year, withdraw the excess plus any net income it earned before your tax filing deadline, including extensions. Your IRA custodian can usually run this calculation if you request a “return of excess contribution.”7eCFR. 26 CFR 1.408-11 – Net Income Calculation for Returned or Recharacterized IRA Contributions
Missed required minimum distributions. Once you reach age 73, you must begin taking RMDs from traditional IRAs and most employer retirement plans by April 1 of the following year.8Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) Fall short and the IRS imposes a 25% excise tax on the amount you failed to withdraw.9Office of the Law Revision Counsel. 26 USC 4974 – Excise Tax on Certain Accumulations in Qualified Retirement Plans Older references cite 50%; the SECURE 2.0 Act dropped the rate to 25% starting in 2023. It drops further to 10% if you correct the shortfall within the correction window, which generally runs through the end of the second tax year after the year you missed the distribution.
How the Form Is Organized
Form 5329 has nine parts, and you fill out only the ones that apply. Knowing the layout up front keeps you from wandering into the wrong section.
- Part I: additional tax on early distributions from IRAs, qualified retirement plans, and modified endowment contracts.
- Part II: additional tax on certain distributions from education accounts and ABLE accounts.
- Part III: excess contributions to traditional IRAs.
- Part IV: excess contributions to Roth IRAs.
- Part V: excess contributions to Coverdell ESAs.
- Part VI: excess contributions to Archer MSAs.
- Part VII: excess contributions to HSAs.
- Part VIII: excess contributions to ABLE accounts.
- Part IX: excess accumulations, meaning missed RMDs, from qualified retirement plans including IRAs.10Internal Revenue Service. Instructions for Form 5329
The top of the form asks for your name, Social Security number, and the tax year. If you are filing as a standalone document for a prior year, write the correct year clearly at the top of the page.
Requesting a Waiver on a Missed RMD
A missed RMD is one of the most common reasons people file Form 5329 on its own, often for a year already in the past. Even the 25% rate can be waived entirely if you show the IRS that the failure was due to reasonable cause and that you have already taken steps to fix it. Complete Part IX, calculate the tax as if it applies, and attach a written explanation for why you missed the distribution. Situations the IRS generally treats as reasonable cause include serious illness or death of the account owner or an immediate family member, natural disasters, and system errors that prevented timely processing.11Internal Revenue Service. Penalty Relief for Reasonable Cause
What does not usually work: claiming you didn’t know about the RMD requirement, blaming your financial advisor, or saying you simply forgot. The IRS has explicitly stated that lack of knowledge, reliance on a tax professional, and mistakes or oversights generally do not qualify as reasonable cause.11Internal Revenue Service. Penalty Relief for Reasonable Cause If you request a waiver, enter “RC” next to the applicable line on Part IX and do not pay the penalty amount with your return. If the IRS denies the waiver, they will send you a bill for the tax plus interest.
Why Filing Matters Even at Zero
If you never file Form 5329 for a year in which an excise tax was due, the statute of limitations for the IRS to assess that tax may not start running. The general rule gives the IRS three years from the date a return is filed to assess additional tax. Without a return reporting the excise tax, the IRS can potentially come after the penalty well beyond that window.
The SECURE 2.0 Act capped the lookback at three years for IRA-related RMD failures even when Form 5329 was not filed. For the 6% excess contribution penalty, the lookback period is six years if the taxpayer filed a Form 1040 but did not file Form 5329 separately. Filing the actual Form 5329 keeps the assessment period at three years for excess contributions as well. These rules apply to tax years beginning in 2023 and later.
The practical takeaway: even in a year where you believe no penalty is owed, filing Form 5329 showing a zero balance starts the clock. Skip it, and if the IRS later disagrees with your calculation, they have a much longer window to come after the tax.
