LLCs are typically taxed on a pass through basis, much like general partnerships. As pass through entities, the profits and losses of LLCs are passed on to the individual owners and are reflected on the owner’s personal income tax returns. Alternatively, LLCS may elect to be taxed as S corporations to potentially reduce the self-employment taxes imposed on the owners.

When beginning a business, you must decide what form of business entity to establish. Your form of business determines which income tax return form you have to file. The most common forms of business are the sole proprietorship, partnership, corporation, and S corporation. A Limited Liability Company (LLC) is a business structure allowed by state statute. Legal and tax considerations enter into selecting a business structure.
Unlike in many other Western countries, Canadian businesses generally only have one form of incorporation available. Unlimited liability corporations can be formed in Alberta "AULC", British Columbia "BCULC"[8] and Nova Scotia "NSULC". The aforementioned unlimited liability corporations are generally not used as operating business structures, but are instead used to create favorable tax positions for either Americans investing in Canada or vice versa.[9] For U.S. tax purposes the ULC is classified as a disregarded entity.
