Final answer:
A corporation would be the best business structure for Jim and Darryl, as it allows them to participate equally, have personal liability protection, expand with diverse owners, and potentially avoid double taxation.
Step-by-step explanation:
The best business structure for Jim and Darryl, who want to participate equally in the business and share profits, protect themselves from personal liability, and have the ability to expand and have diverse owners, would be a corporation.
A corporation is a separate legal entity that offers limited liability protection to its owners, known as shareholders. Both Jim and Darryl can be equal shareholders in the corporation, meaning they would share in the profits based on their ownership percentage.
Additionally, a corporation allows for the issuance of different classes of shares, which can be beneficial in the future if Jim and Darryl want to bring in new investors or have different ownership structures. A corporation also has the advantage of being able to raise capital through the sale of stock, which can help with business expansion.
Finally, a corporation can avoid double taxation by electing to be taxed as an S corporation. This means that the profits of the business are only taxed at the individual level, avoiding corporate-level taxation.
