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

@SSRRS

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.
