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.
Depending on elections made by the LLC and the number of members, the IRS will treat an LLC as either a corporation, partnership, or as part of the LLC’s owner’s tax return (a “disregarded entity”). Specifically, a domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and affirmatively elects to be treated as a corporation. For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and elects to be treated as a corporation. However, for purposes of employment tax and certain excise taxes, an LLC with only one member is still considered a separate entity.
