My return has 0 in AGI because I am using FEIE. can I e-file?

Bigger question - are you even required to file? if AGI is less than the standard deduciton, then it is not required.  (but filing is the only way to get withholdings/ estimated payments back)

If you are excluding all your income the trick to be able to efile is to simply enter $1 of bank interest to have a $1 AGI.
