Email notifications to taxpayers upon successful e-filing

No there isn't such an option.  And that's all I will say about it today.

Certainly would be nice. 

The issue with what you want is that most likely it would send notification of the Federal acceptance but what about those states and those that don't acknowledge right away, or the FBAR which could take longer.

Once a day I send out one email with bcc (blank carbon copy) to all the clients who are 100% accepted. It is an extra step.  Prior to that I had postcards printed up and would just drop them in the mail.  50% never made it to the recipient.

Clients pay us to properly prepare and submit their tax returns.  We give them a copy of the return before the return is submitted.  I’m not sure why we need to submit proof to the clients that the return was accepted.  Back in the days of paper filing, did preparers provide their clients with USPS certified receipts that the IRS received their tax returns?
