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.
Limited liability companies can raise money via banks and investors but cannot sell stocks. S-Corps can get loans from banks, as well as distribute stock to up to 100 people. C-Corps have the easiest time raising capital as there is no cap on how many people can own stock. Non-Profits can both get loans and receive tax-deductible donations. Sole Proprietorships can occasionally receive bank loans but cannot sell stocks.
After you register your business, you may need to get an employer identification number (EIN) from the IRS. While this is not required for sole proprietorships with no employees, you may want to apply for one anyway to keep your personal and business taxes separate, or simply to save yourself the trouble later if you decide to hire someone else. The IRS has provided a checklist to determine whether you will require an EIN to run your business. If you do need an EIN, you can register online for free.

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.
