After you've completed the steps described above, your LLC is official. But before you open your doors for business, you need to obtain the licenses and permits that all new businesses must have to operate. These may include a business license (sometimes also referred to as a "tax registration certificate"), a federal employer identification number, a sellers' permit, or a zoning permit. For more on business licenses and permits, see the Licenses & Permits for Your Business area of Nolo's website.
Another important component when you are determining how to form an LLC is the creation of an LLC operating agreement. While operating agreements are not required under state law when forming an LLC and do not have to be filed with the state, they are very important documents to create because they help you and any other members of the LLC organize your business, plan for the future, and put all pertinent facts in writing.
Please do not place your social security number on filing or other documents you submit to the Secretary of State. Although we attempt to prevent disclosure of social security numbers, due to the large number of documents filed, we cannot guarantee that a social security number placed on a document will not be disclosed. It is the responsibility of the filer to ensure that a social security number is not contained on the filing.
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.
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.
