Section 12 SOAP Fault Response Messages

Publication 5258 — Guide for Affordable Care Act (ACA) Information Returns (AIR) Submission Composition and Reference Guide · 2026-10-03 edition · updated 2026-10-04 · United States

Instead of a response SOAP message, IRS may send a SOAP fault message to the transmitter if request SOAP message has a fatal error. This section describes conditions that will result in SOAP fault.

1. When the transmission through the UI or A2A transmission channel is rejected in IRS portal, there are indications that there is an error in the message pertaining to things like the SOAP envelope (Headers or Body), certain rules pertaining to the SOAP message have not been followed (such as the Form Data File exceeds the 100 MB file size constraint), the WS-Security elements are incorrect, potential XML threats have been detected either in the message or the MTOM attachment, and other possible problems.

2. A triggered SOAP fault, with a description, will be displayed on the page as applicable. The blue Download button, normally used to retrieve the error data file for the UI channel user, will not be available in this situation.

12.1 | ISS-Portal Error Codes and Messages

The error codes and messages included in Table 12-1 provide information that would be returned from IRS to the Transmitter in the event a transmission is rejected before it can be transmitted to AIR. These error codes are specifically prefixed with “TPE” to identify that the transmission was rejected before it got to AIR.

In the event a Transmitter receives one of the fault codes included in the following table, they must address the cause of the rejection and resubmit the transmission.

Table 12-1: Portal Error Codes (Fault Codes) for Tax Years 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 and 2026
