I’m just starting out and I have 3 clients. I have a full time job so preparing taxes would be more like a side hustle for me.

I have a PTIN but not an EFIN, and I see it takes 45 days to obtain after you apply.

All of the professional software I see says you are required to have an EFIN, but I see the IRS rules are that you are only required to use an EFIN if you file more than a certain number of returns.

Is there a software or 3rd party E-File provider that you can use if you are a professional tax preparer that does not yet have an EFIN?

Thank you for your help!!
