Answer: Limited liability company
Step-by-step explanation:
Based on the information given in the question, I'll tell Joji to consider a limited liability company. A limited liability company simply refers to a private company whereby in the case if a liability, the owners are only legally responsible to the debt based on the amount that they contributed.
Since John would like to minimize his taxes and protect his family, the limited liability company should be chosen as he will be taxed just exactly like a sole trader and his assets will be protected as well.
