IL Preparer EIN Required for e-file

Are you sure the error says FEIN, or is it EFIN, also in preparer section you should put PTIN, and leave SS number blank in addition in the preparer section there is no firm EIN only firm number IE firm 1, firm 2 ETC

I have the same error for IL returns even ones I’ve already filed

I saw a report of this last week in the Facebook PS group, it must have rode in on an update.

​@Kathi_at_Intuit  any input on this?

​@drbdrb Even if this is an “unexpected behavior” in Intuit speak, it’s 2026 and you’re plastering your SSN all over the place? Get an EIN. It takes about 3 minutes online.

IL does not require a self employed tax preparer to have an EFIN. They do require you to have an EFIN and PTIN if you prepare taxes for a fee. You must have an error in the software. You should do all normal trouble shooting steps, and try again.

I think were mixing up EFIN and FEIN.

Hi ​@drbdrb we wanted to give you an update. Our Support team is currently investigating this issue. They are reviewing the Illinois e-file business rules to determine whether those requirements are causing the error to trigger.

In the meantime, we've been advised that you can work around the error by entering your SSN in Tools > Options > Firm/Preparer Info > Firm Information > Employer ID# (EIN).
