Limited liability companies allow for a large variety of management structures based on your specific needs. Management structures for S-Corps are largely dictated by state and federal law. Management schemas for C-Corps are largely dictated by state and federal law. NPOs need to follow strict management laws to guard their non-profit status. Since Sole Proprietorships have only one member, there is no management structure.
While limited liability companies have less compliance requirements than other entity types, there are reports and licenses that need to be filed and maintained. S-Corps usually will need to file reports and pay compliance fees on an annual or semi-annual basis. C-Corps generally must file reports with their state, as well as a host of other regulatory and compliance fees. Non-Profits have more compliance responsibilities than other entities as they must continually preserve their tax-exempt status. Sole Proprietors do not have ongoing compliance fees.
LLC members are not personally responsible for the company's debt or liability. S-Corp shareholders are not personally responsible for the company's debt or liability. C-Corp shareholders are not personally responsible for the company's debt or liability. Non-Profit directors are not personally responsible for organizational debt or liability. Sole Proprietors are personally responsible for debt and liability.
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.
