A limited liability company (denoted by L.L.C. or LLC) is a legal form of business company in the United States to its owners.
In that respect, it is similar to a corporation, and is often a more flexible form of ownership, especially suitable for smaller companies with a limited number of owners. Unlike a regular corporation, however, a limited liability company with one member may be treated as a disregarded entity, so the member is often singled-out as a person performing the actions of the LLC. A limited liability company with multiple members is typically treated as a partnership for tax purposes, thereby avoiding double taxation. An LLC can elect to be either "member managed" or "manager managed."
Operating as an LLC form of partnership does not mean that appropriate federal partnership tax forms are not necessary, or not complex. As a partnership, the entity's income and deductions attributed to each member are reported on that owner's tax return.
LLCs can lose their tax advantage without the partnership structure. The possible label "disregarded entity" for income tax purposes singles out the one-member owner of an LLC as actually earning income and deductions directly. It is the owner, then, who reports as a business proprietor, rather than as an LLC operating an active trade or business. An LLC passively investing in real estate and owned by a single member would have its income and deductions reported directly on the owner's individual tax return on a Schedule E tax form. And an LLC owned by a corporation--in other words, an LLC with a single corporate member--would be treated as an incorporated branch and have its income and deductions reported on the corporate tax return, creating double taxation.
According to the New York Department of State, Section 206 of the NY State Limited Liability Company Law requires that within 120 days after the effectiveness of the initial articles of organization or application of authority, a limited liability company (LLC) or Professional LLC must publish
