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.
Doing Business As: denotes a business name used by a person or entity that is different from the person's or entity's true name. DBAs are not separate entities and do not shield the person or entity who uses the DBA as a business name from liability for debts or lawsuits. Filing requirements vary and are not permitted for some types of businesses or professional practices.
