A series LLC is a form of limited liability company that provides liability protection to multiple "series". Essentially, it's a master LLC with separate divisions, each protected and operating independently. As an entity, the series LLC is geared towards businesses where investors own multiple companies, with each series being protected from the debts and obligations of the other series. Currently, only several states support this option, including Delaware, Illinois, Iowa, Nevada, Oklahoma, Puerto Rico, Tennessee, Texas, and Utah.
No Ownership Restrictions The LLC does not have any residency or citizenship restrictions, which allows foreign nationals to have ownership in an LLC, if desired. In addition, other corporate entities may be LLC members which means that other corporations or LLCs (or other entities) may be a member of the LLC, or may be the sole member (although an LLC with a sole member that is a corporation or LLC is treated for tax purposes as a partnership or multi-member LLC).
Unltd or Ultd (Unlimited/無限公司): similar to a limited liability company (Ltd) but whose members or shareholders do not benefit from limited liability should the company ever go into formal liquidation. It is not a requirement under company law to add or state the word or designation Unlimited (無限公司) or its abbreviations (Unltd or Ultd) at the ending of its legal company name, and most unlimited companies do not.
Louisiana (except for railroad, telegraph and telephone corporations) "Corporation", "Incorporated" or "Limited", or the abbreviation of any of those words, or may contain instead the word "Company" or the abbreviation "Co." if the latter word or abbreviation is not immediately preceded by the word "and" or the symbol "&". No corporate name shall contain the phrase "doing business as" or the abbreviation "d/b/a". Only a bank or bank holding company is allowed to use any of "bank", "banker", "banking", "savings", "safe deposit", "trust", "trustee", "building and loan", "homestead", "credit union", "insurance", "casualty", "redevelopment corporation", or "electric cooperative". § 12:23 Louisiana Revised Statutes
Depending on how your business is structured, the amount of revenue your business earns, and several other factors, forming an LLC can provide potential tax benefits for business owners. LLCs are allowed to choose how they want to be taxed, either as an S corporation or C corporation. These options are not available when you are operating as a sole proprietorship. LLCs don't pay their own taxes directly, the income of the business its passed on to the members of the LLC through "pass through taxation." This means that a member is subject to self-employment taxes, but at higher levels of income, the LLC can often pay a lower base tax rate than a C Corporation. The best way to determine your potential tax benefits is to consult an accountant.
