Will we be able to e-file this year?

Yes. The IRS has released a timeline for accepting e-filed returns with the new Schedules K-2 and K-3. Partnership returns have the earliest date:

Form Number                                             Date Available

Form 1065, Schedules K-2 and K-3           March 20, 2022

Form 1120-S, Schedules K-2 and K-3        Mid-June 2022

Form 8865, Schedules K-2 and K-3           January 2023

Note that these dates reflect the earliest dates that the IRS will begin accepting the e-filed tax returns. It may take additional time (typically, a few weeks) for these forms to be finalized in tax preparation software.

Fortunately, as indicated above, the IRS has also provided a workaround to allow partnerships to e-file earlier, if they so choose. Partnerships can file by March 15 if Schedules K-2 and K-3 are included as an attachment to the return (rather than as forms within the return).
