Hi Jackie, there are two types of LLCs. One is a single-member LLC which has one owner and is required to file Schedule C along with Form 1040. The 2nd type of LLC is called a multi-member LLC and that means that you have more than 1 owner. For this type of LLC, you must file Form 1065 which is the tax return for partnerships. Check out our guide below for step by step instructions on how to complete a Schedule C and how to complete Form 1065:
