Some businesses are prevented from forming an LLC, however. Typically financial companies such as banks, financial trust companies and insurance agencies can't file as an LLC. LLCs are sometimes limited for industries in certain states, too. For example, if you live in California, you can't form an LLC if you're an architect, accountant or licensed health care provider. Check out our LLC information by state for more details on your state.
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" 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. For U.S. tax purposes the ULC is classified as a disregarded entity.
