Thank you all. The LLC was formed on April 6, 2021, and we obtained the EIN shortly after, in May. In November of the same year, we changed the classification to a C-corporation and filed taxes for the first year as a corporation. The tax classification is the only change. It is a single-member LLC with no employees. I just want to confirm whether a new EIN was required, given that the only change was the tax classification.
