Follow up question @Mike9241 . Let’s say you file in march. However you notice that you missed something and want to file amendment. If your original file is still processing, but you don’t want to incur interest (the 4.5% you mention), can you pay early (before April 15th), and send in the amendment after the original was approved? Would that mean no interest would apply if they can see you paid by the due date? Hope you can follow what I mean!
