If they get their SS, SSDI or RR retirement as direct deposit, they don't need anyone to do anything on their behalf. The banking info is already being provided.

The IRS has two sites: one for Nonfilers and one for those filers who never provided banking info for any direct deposit reason. There is nothing that prevents their tax preparer from using the portals on behalf of the client.

I don't understand why anyone thinks filing a paper return under the EIP provision would make sense at this point.
