The exact wording is:
A sole proprietor files papers to become a state recognized entity, organizes as an LLC, and will file Form 8832 or Form 2553 to elect to be treated as a disregarded entity or taxed as a corporation or small business corporation.
FWIW, the LLC was formed back in March, and an EIN obtained at that time for banking purposes. Business checking was opened last month, and the SMLLC will co-exist alongside the sole prop (although dormant) until early 2021, at which point the sole prop's accounts will be shut down after everything is transferred over.
No 8832 nor 2553 was filed, as the default federal income tax status of the SMLLC is disregarded entity, and that's what I want to keep it as for the time being.
Like it or not, the SMLLC EIN is not the same as the sole prop EIN in this fact pattern, even if it could/should have been.
