Depending on how your business is structured, the amount of revenue your business earns, and several other factors, forming an LLC can provide potential tax benefits for business owners. LLCs are allowed to choose how they want to be taxed, either as an S corporation or C corporation. These options are not available when you are operating as a sole proprietorship. LLCs don't pay their own taxes directly, the income of the business its passed on to the members of the LLC through "pass through taxation." This means that a member is subject to self-employment taxes, but at higher levels of income, the LLC can often pay a lower base tax rate than a C Corporation. The best way to determine your potential tax benefits is to consult an accountant.
With the proper planning, limited liability companies can exist for generations. S-Corps continue to exist even if the owners or majority shareholders leave or pass away. C-Corps continue to exist even if the owners or majority shareholders leave or pass away. Non-Profit organizations and institutions survive after their directors leave. Sole Proprietorships do not exist when the owner quits or passes away.
