A standalone Form 5329 goes to one of three IRS service centers, and which one depends on the state you live in. Kansas City handles most of the East Coast and Midwest, Austin covers the South and all foreign or APO/FPO filers, and Ogden takes the West and Plains states. You cannot e-file Form 5329 on its own; it has to be printed, signed, and mailed, with any penalty payment enclosed. The addresses below come from the 2025 Form 5329 instructions, and the IRS does reshuffle state assignments from year to year, so pull the current instructions before you drop it in the mail.1Internal Revenue Service.

Certified mail with a return receipt is worth the extra dollar or two. That receipt is your proof of the date the IRS received the form, which matters for payment deadlines and for starting the statute of limitations.
When Standalone Filing Is Actually Correct
Most people attach Form 5329 to their Form 1040 for the year and never mail it separately. Standalone filing is only right in two situations:2Internal Revenue Service. Instructions for Form 5329 (2025)
- Your income is low enough that you have no Form 1040 filing requirement, but you still owe a Form 5329 penalty — for example, a small early IRA withdrawal with little other income.
- You already filed a prior year’s Form 1040, forgot to include Form 5329, and have no other changes to that return. You file that prior year’s version of Form 5329 by itself.
If you do have other changes to a prior-year return, don’t send a standalone Form 5329. Use Form 1040-X for the amended return and attach Form 5329 to it.1Internal Revenue Service. Instructions for Form 5329
Deadline
A standalone Form 5329 is due when your Form 1040 would have been due for that tax year, generally April 15 of the following year. The instructions direct you to file it “at the time and place you would be required to file Form 1040, 1040-SR, or 1040-NR.”2Internal Revenue Service. Instructions for Form 5329 (2025) If you’re catching up on a missed prior year, use that year’s version of the form and send it in as soon as you can. Interest keeps running until the balance is paid.
Filling In the Header and Signing
Because a standalone form isn’t attached to a 1040, the IRS has no parent return to pull your details from. Complete the header at the top of page one with your full name, current address, and Social Security number. A mismatch or a missing SSN here is the most common reason these forms get stuck in processing.
Complete only the parts of the form that apply to your situation. Common ones are Part I (10% additional tax on early distributions before age 59½), Parts III through VIII (6% tax on excess contributions to IRAs, HSAs, Coverdell ESAs, Archer MSAs, and ABLE accounts), and Part IX (tax on missed required minimum distributions).1Internal Revenue Service. Instructions for Form 5329 The form totals your additional tax on a summary line near the end.
Sign and date the form at the bottom before mailing. An unsigned Form 5329 is treated as not filed, which means the statute of limitations clock never starts.
Paying the Additional Tax
The penalty on Form 5329 is due when you file. It is separate from any regular income tax and needs its own payment.
If you’re paying by check or money order, make it payable to “U.S. Treasury.” Write your name, Social Security number, the tax year, and “Form 5329” on the check so the IRS credits it correctly.3Internal Revenue Service. Pay by Check or Money Order Do not enclose Form 1040-V. That voucher is built for Form 1040 balances and will route your payment to the wrong place.
You can also pay electronically through IRS Direct Pay or EFTPS. Choose “Form 5329” as the form type and select the correct tax year so the payment posts to the right account. Electronic payment gives you an immediate confirmation number, which is faster proof than waiting for a mailed check to clear.
Why Filing Starts the Clock
Filing Form 5329, even by itself, starts the statute of limitations for the IRS to assess the penalty. If you never file, the clock never starts, and the IRS can come after the tax years later.4Office of the Law Revision Counsel. 26 U.S. Code 6501 – Limitations on Assessment and Collection The IRS does eventually match 1099-R data against filed returns, so skipping the form is not a safe strategy.
If you think you don’t owe a penalty for a year but want to close it out, you can file Form 5329 showing zero tax and attach a short explanation. That starts the limitations period running even though no money changes hands.
