Final answer:
Yes, a sole proprietor can form a single-member LLC, which would be taxed as a sole proprietorship.
Step-by-step explanation:
Yes, a sole proprietor can form a single-member limited liability company (LLC). This allows the owner to enjoy the benefits of limited liability protection while still maintaining the simplicity and flexibility of a sole proprietorship. The LLC would be taxed as a sole proprietorship, meaning that the profits and losses of the business would flow through to the owner's personal tax return. This is known as pass-through taxation.
