I let the software print my name in the signature box.  These days that counts as a signature on the return.

I have the software print my name in the signature box as well.    If it's good enough for IRS, its good enough for them.

I never wet sign a copy, only an original.

My name prints, too.

Contrary to what others have posted, I sign every return before mailing, as well as have the software print my name in the signature box. I do this (a) as sometimes a return is printed, corrected, and reprinted; my signature tells me that is the final version, and (b) it shows the clients (who actually look at a return) that I went through each page of the return.  Maybe not required, just my preference.

@Johnl777 @abctax55 @dascpa @Accountant-Man @Just-Lisa-Now- @IRonMaN great points from all...like dascpa said, imo it is a good idea to sign both the return and the e-file signature document....

Thanks for your answer. Agrees with Rev Ruling 78-317, even though IRS website says otherwise it appears as stated in 2/5/21 post of "Beware of "ghost" preparers who don't sign tax returns." I think, but could be wrong, the key is for the preparer to sign and date the Form 8879 e-file authorization, as well as get his taxpayers to sign and date the same, before efiling the return. Then the taxpayer copy can be given to the client unsigned, if I am reading the RR correctly. Take care and thanks.

That ghost reference refers, for example, to "preparers" using Turddoh Tax who hand the client a tax return that says Prepared by a Nonpaid Preparer

I dont think 'non paid preparer' is an option in TT...its purely DIY so nothing prints in the Paid Preparer area.

You will see ghost preparers that use the cheapest professional software they can find and will mark returns as Self Prepared and not put any preparer info at all.

That must be what I've seen.

I ain't afraid of no ghost.
