If they filed a return on the non filer site, then you will not be able to Efile the actual return....they will be stuck mailing it in and might see their refund by Christmas....the site clearly explained that it was only to be used if they didnt have a reason to file an actual return.

...and if you're relying on a bank product for payment of your fee  . . .

I'm glad others are around to take care of the clueless taxpayers, because that leaves the other kind for me.  

I would charge them an extra $1201 for the extra work.  😉
