Amend 5500 and also ck off 5558?

Hi 

Thank you as always for all the valuable knowledge and input.

Is there an issue, if amending a 5500 for the current year to have both the 5558 box and the amended box checked off, or don't confuse things and just ck off amended? Thank you.

Assuming there was a 5558 filed to extend the original filing and the box was checked on the original filing, then check the 5558 box on the amended return.

An amended return replaces the original filing in the EFAST2 records.

Thank you Paul I. Yes, the original filing had an extension filed and the 5558 box was indeed checked on the original filing. Will they get confused if both the 5558 and the amended  boxes are checked off? Or does it look like asking now for an extension with the amended filing (or does it imply that forgot to ck off the 5558 on the original filing and now fixing that)? Thank you!

They look only at the amended return.  If the 5558 box is checked, they will see that the original filing was put on extension.

The very short version is you don't file an extension for an amended return, but an amended return should disclose that the original filing originally was extended.
