Here is the short version. Form 15434 was tied to two time‑boxed IRS programs. The first ran in late 2023 through March 22, 2024 and let you repay 80% of the ERC you received, which is a built‑in 20% reduction, with no interest if you paid by the time you signed the closing agreement. The second ran from August 15, 2024 through November 22, 2024 and required repayment of 85%, which is a 15% reduction, focused only on 2021 quarters. Both programs are now closed, so Form 15434 is not available for new submissions.
If you see Form 15434 floating around online, treat it as historical reference. The submission window ended at 11:59 p.m. local time on November 22, 2024, and the IRS page for the program is marked closed.
Key takeaways
- Form 15434 was the IRS application for ERC voluntary disclosure. It is closed to new submissions as of November 22, 2024.
- Two rounds existed. Round one, Dec 22, 2023 to Mar 22, 2024, required 80% repayment, a 20% reduction. Round two, Aug 15, 2024 to Nov 22, 2024, required 85% repayment, a 15% reduction, and applied only to 2021.
- If your ERC refund was not paid, or a check was never cashed, you can still use the ERC Claim Withdrawal process to stop the claim.
- If only part of a quarter was wrong, fix it with an adjusted employment tax return, usually Form 941‑X, one quarter at a time.
- For 2025 policy context, IRS guidance notes that claims filed after January 31, 2024 are disallowed under current law. Plan any cleanup with that in mind.
What Form 15434 did, and why it is closed now
Form 15434 was your application to enter the ERC Voluntary Disclosure Program. In the first round, you repaid 80% of what you received. You did not repay any interest the IRS may have paid you, and if you paid in full by the time you signed the closing agreement, the IRS did not charge new interest. That round closed March 22, 2024.
The second round, which opened August 15, 2024 and closed November 22, 2024, shifted terms. It covered only 2021 periods and required you to repay 85% of what you received. As before, if you paid the required balance by the time you returned the signed closing agreement, you avoided additional interest and penalties tied to that repayment. After November 22, 2024, the portal was shut.
Who Form 15434 was for, and common disqualifiers
If you actually received ERC for a 2021 quarter and later concluded you were not eligible, Form 15434 was the on‑ramp into the second disclosure program. It was not a way to claim ERC. You needed to submit the package through the IRS Document Upload Tool, follow the form’s instructions, and be prepared to repay the net amount due under the program. Third‑party payers, such as PEOs and CPEOs that filed under their own EIN, had to file the package for their client groups, often attaching the relevant Schedule R pages.
You could not use Form 15434 if the refund had never been paid or was still an uncashed check. Those situations belong in the ERC Claim Withdrawal Program, which stops the claim and treats it as if it was never filed.
First vs. second ERC voluntary disclosure programs, at a glance
| Term | First round, 2023–Mar 22, 2024 | Second round, Aug 15–Nov 22, 2024 |
| Repayment amount | 80% of ERC received, you keep 20% | 85% of ERC received, you keep 15% |
| Covered periods | 2020 and 2021, based on program rules | 2021 quarters only |
| Interest you previously received | Not repaid | Not repaid |
| New interest or penalties | Not charged if you paid in full by signing | Not charged if you paid in full by signing |
| Application vehicle | Form 15434 via IRS Document Upload Tool | Form 15434 via IRS Document Upload Tool |
| Status in 2025 | Closed | Closed |
The differences matter because you might still see articles quoting the 20% figure. That applied to the first round. If you are modeling exposure for past quarters in internal forecasts, use the correct percentage for the round you actually entered, and remember both rounds are closed.
What to do now, decision paths for 2025
If you need to fix ERC today, start by matching your situation to the right path.
- Your ERC refund was never paid, or you received a check and did not cash it, use the ERC Claim Withdrawal Program. This stops the claim, avoids penalties and interest on that withdrawn claim, and treats it as if it was never filed. Follow the exact fax or mail steps, and keep copies.
- Your ERC was paid and you now believe it was wrong, the disclosure programs are closed, so Form 15434 is not available. Monitor IRS notices, consider proactive repayment only if instructed by the IRS, and prepare your files, workpapers, and correspondence. If you used a third‑party payer, coordinate with them because they filed under their EIN.
- Only part of a quarter was wrong, correct that quarter with an adjusted employment tax return, typically Form 941‑X. File one per quarter, explain the change, and follow the timing rules for interest‑free treatment on underreported tax where available.
How to withdraw an unpaid ERC claim
If your refund has not been paid, or you have an uncashed check, the withdrawal program is still open. Here is the nutshell version of the steps.
- Make a copy of the adjusted return you filed to claim ERC, for example Form 941‑X.
- Write “Withdrawn” in the left margin of page 1. On the right margin, have an authorized person sign and date, and include their printed name and title.
- Fax the signed copy to 855‑738‑7609 if you have not been notified of an audit. If you are under audit, give it to your examiner as instructed.
- If you have a refund check you have not cashed, write “Void” on the endorsement line, include a brief note that says “ERC Withdrawal” with your reason, make copies, and mail to the IRS Cincinnati Refund Inquiry Unit per the instructions.
The IRS will mail you a letter approving or rejecting the withdrawal. Keep that letter with your records. If approved, the claim is treated as if it was never filed.
How to fix a partial error with Form 941‑X, 2025 edition
When only part of a quarter is wrong, use Form 941‑X for that quarter. File one 941‑X per quarter, explain your adjustments in plain language, and pay any balance due by the time you file to protect yourself from extra charges where the rules allow interest‑free treatment. The April 2025 instructions walk through timing, address changes, and where to send the form if you cannot e‑file. Build a short memo that states what changed, when you discovered it, and why it was incorrect. It keeps reviews fast and lowers back‑and‑forth with the Service.
Quick comparison, which path fits
| Scenario | Correct path | Why this fits |
| Filed 941‑X, refund not paid | ERC Claim Withdrawal | Stops the claim, no penalties or interest for the withdrawn claim |
| Received check, did not cash | ERC Claim Withdrawal with voided check | Returns the check, closes the loop |
| Paid refund, quarter partly wrong | Form 941‑X for that quarter | Quarter‑by‑quarter correction rules |
| Paid refund, fully ineligible | VDP windows are closed, prepare for IRS contact, keep documentation, coordinate with third‑party payers if used | Form 15434 cannot be filed now |
Keep your compliance map current
Two more items for your 2025 checklist. First, claims filed after January 31, 2024 are disallowed under current law, and the IRS has published FAQs about how that works in practice. Make sure your team does not plan on late claims as an offset in any financial model. Second, the IRS moratorium history, audits, and promoter enforcement are still shaping reviews, so maintain organized files, eligibility analyses, gross receipts schedules, and any government order documentation for suspension claims.
The simplest way to reduce audit fatigue is clean documentation. Label files, standardize naming, and include a short one‑page eligibility summary per quarter.
Examples, documentation checklist, and a light touch on delivery
Three quick scenarios
- Example 1, uncashed check. You filed a 941‑X for Q3 2021, a check arrived, and it has been sitting in a drawer. You now believe you were not eligible. You use the withdrawal process, void the check, include a short note explaining why, and mail it with a signed withdrawal request. When the IRS sends the acceptance letter, you are done with that claim.
- Example 2, partial error. Your Q2 2021 ERC was overstated because one location did not actually meet the gross receipts test. You file a 941‑X for Q2 2021 to reduce the credit for that quarter only. You attach a clear explanation and pay any amount due at filing.
- Example 3, paid and ineligible, VDP closed. Your Q3 2021 ERC was paid, and after a fresh review you determine you were not eligible. Since the second VDP closed on November 22, 2024, you cannot submit Form 15434 now. You organize your workpapers, gather advisor details used in the original claim, and prepare for IRS contact. If a third‑party payer filed on your behalf, you coordinate records with them since returns were filed under their EIN.
Documentation checklist you will be glad you kept
- Quarter‑by‑quarter eligibility memos, including gross receipts tests and any government order analysis
- Copies of all Forms 941, 941‑X, and any Schedule R if a third‑party payer was involved
- Proof of any refund received, deposit records, or uncashed checks
- Copies of correspondence, including withdrawal request fax confirmations or tracking
- If you entered a past disclosure program, your executed closing agreement and your payment proofs
- Names and contact information for advisors or promoters involved in your original claim, which the IRS asked for in the application process when those programs were open

FAQs
Is Form 15434 still available?
No. Both ERC voluntary disclosure windows are closed, and the IRS marks the program pages as closed. Treat the form as historical reference unless the IRS opens a new round in the future.
I never cashed the ERC check. What is my best option?
Use the ERC Claim Withdrawal Program. Void the check, include a brief explanation, copy everything for your files, and mail to the IRS per the instructions. The IRS will confirm acceptance or rejection by letter.
I was only partly wrong in a quarter. How do I fix that?
File an adjusted employment tax return for that quarter, usually Form 941‑X, with a clear explanation. Follow the 2025 instructions for timing and payment to minimize extra charges where possible.
What were the actual reduction percentages in the disclosure programs?
Round one let you repay 80%, which is a 20% reduction. Round two required 85%, which is a 15% reduction, and it applied only to 2021 quarters. Both rounds are closed.
Can I still file a late ERC claim now?
IRS guidance in 2025 explains that ERC claims filed after January 31, 2024 are disallowed under current law. Focus on cleanup, not new claims, and consult your advisor before taking any action.
Final word and compliance note
You want clarity, not more noise. If your claim was not paid, withdraw it. If a quarter was partly wrong, file 941‑X for that quarter. If you were paid and ineligible, keep your records tight and be ready to respond. If you need extra hands to standardize workpapers and speed reviews, bring in disciplined help for the busywork so you keep control of the decisions.
