Technically. In practice, no self-employed or small business people obey those laws. No one could run a business if they had wade through mountains of government paperwork, the only intent it seems, is to eat through the substance of one’s existence. There are lots of laws on the books that never get enforced because society would grind to a complete halt if they were enforced.
In practice, if you want to take in money you have to comply with those laws. If you take money and the Franchise Tax Board finds out, woe be unto you if you are not in compliance.
