The "mit beschränkter Haftung (mbH)" suffix (German: [ˈɛmbeːˌhaː], "with limited liability") is sometimes added to the name of a firm that already ends in "-gesellschaft" ("company"), e.g., "Mustermann Dental-Handelsgesellschaft mit beschränkter Haftung" ("dental trading company with limited liability"), which would be abbreviated as "Mustermann Dental-Handelsgesellschaft mbH".
File with the appropriate federal, state, and local governmental agencies. Depending on the business purpose of your LLC and the jurisdiction in which you organize, you may have to file additional forms relating to LLCs with certain governmental agencies. Each industry is regulated differently—as is each local jurisdiction—and so it is best to ask an attorney or accountant for assistance in this matter.
Since limited liability companies can be a pass-through entity, owners are taxed on their personal income. S-Corp shareholders are taxed personally. The S-Corp, however, is not. C-Corp income is taxed at the corporate level first, then again at the personal level. This is called "double taxation." Non-Profits are only taxed once and can write off most of their expenses. Sole Proprietors are taxed only on their personal tax return.
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.
