You should draft an operating agreement for your LLC that spells out the details of the business arrangement, including members' percentage ownership, roles, rights and responsibilities.
The LLC structure is a good way to "wall off" your personal assets from your company's liabilities, offering protection for your personal assets in the event of a liability or judgment against your business.
A limited liability company (LLC) also has certain tax advantages. The business itself is not responsible for taxes on its profits. Instead, the LLC's owners, known as "members," report their share of business profit and loss on their personal tax returns, similar to tax reporting for a General Partnership. This is known as "pass-through" taxation.
