To become an officially recognized business entity, you must register with the government. Corporations will need an "articles of incorporation" document, which includes your business name, business purpose, corporate structure, stock details and other information about your company. Otherwise, you will just need to register your business name, which can be your legal name, a fictitious "doing business as" name (if you are the sole proprietor), or the name you've come up with for your company. You may also want to take steps to trademark your business name for extra legal protection.
Self Employment Taxes Although we listed Pass Through Taxation as an LLC benefit, it can also be a disadvantage. Oftentimes the taxes that are passed through and reported as personal income of LLC members will be higher than the taxes at a corporate level. You will also still pay for federal inclusions such as Medicare and Social Security. If you're confused if this business structure will be the right tax choice for you, it's a good idea to speak to your accountant or financial advisor.
