Bear in mind the differences between state tax law and state business law. Whatever tax status you select for your entity beneath the federal check-the-box system, keep in mind that you may be considered a different type of entity for state business law purposes. This means that if you choose corporate tax treatment for a partnership, it will not necessarily bring corporate limited liability.
A state normally treats the entity selected under federal check-the-box as the entity acknowledged for state tax purposes, but this is not always the case.
The law of a state may agree to pass-through status for an entity like an S Corp or an LLC, but still enforce some sort of tax on the entity.
