One of the reasons small businesses have been hit so hard with this is because for then (when incorporated as LLCs), their tax rate is 37% + state + local. I live in NYC and my LLC has a combined tax rate of 50%.
An LLC can either file as a c corp and get corporate tax rates, or (sometimes) file as passthrough like as in a sole proprietorship. Or as a partnership. It gets complicated
Which is not(?). According to https://en.wikipedia.org/wiki/Corporate_tax_in_the_United_St... , federal corporate income tax rate is 21%, + additional <10% for state level, not sure about local level.
