Some extra benefits on tax/gst payments but basic reward structure for common cards used to be the same as normal version cards (moneyback & regalia vis-a-vis business moneyback & business regalia). Now hdfc has launched Biz series completely differentiating normal & business cards but still they are approving biz series cards for those already holding business moneyback/regalia or declared themselves as "self employed' in cc application earlier when business card approved not even asking if they still want business series card as if self employed persons don't need normal cards for their personal usage but only business version cards for their business usage.
