5558 error

Hi,

Thank you as always for all the insights. The 5500 for a 6/30/2025 plan year end, is due by 1/31/26. This came out on Saturday. Therefore, the 5500 and the 5558 must be filed ON or prior to 2/2/26 (since 2/1 26 was a Sunday). We filed the 5558 on 2/2/26 ( today) with I file and got a validation error that stated " you have filed the form 5558 after the return's normal due date and may not be approved for an extension based on this form 5558 that was submited". I hope this is an error on their part and the extension will be approved? Thank you

Did you file using third party software (FIS, FTW, etc...)?

Did you get an AckID, or did this prevent you from actually getting it filed?

While I agree it sounds like an error on their end, it will probably take quite a bit of back and forth to get it resolved. 

RatherBeGolfing, thank you.  It was filed with the efast system and not a 3rd party software. They gave me an option to press submit, and file it, with the error. After hitting submit, they said it t was successfully received.

Sounds like you have an AckID then, so you can prove that it was filed.  I would start with EFAST support, but when it comes to issues beyond what can be found in the instructions to the forms, they usually refer you to Office of the Chief Accountant at the DOL at 202/693-8360.
