Dear  Lavonya Bess:

Thanks for choosing InfoTaxSquare.com for your business needs. Corp or Inc are just indicators use after the business name in most states to register a business name. Board Members should be elected in the board meeting.

Yes Frank, you can still use Inc. Sub-Chapter "S" does not change the indicator like Inc. Corporation.
Thanks for using InfoTaxSquare.com.
