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.
