Hi,

Owner and the Company/Firm are both the different entities. 
Owner's Equity itself is a liability for the firm/Company 
as the owner has invested it into the firm.

Hope this helps.

Thanks,
Abhijit

liabilities means any amount borrowed from outside, it
involves all current liability, long term loans, payment
dues etc. on the other hand owner's equity means interest of
owner in business. like the amount of profit.
