I know that the following are considered liabilities, but I am wanting to make sure that I have this right.

Accounts Payable
Interest Payable
Long-term Notes Payable
Capital

Also, how would owner's withdrawals be listed on the balance sheet if they are even listed on there.

Accounts Payable and Interest Payable are Current Liabilities

Long-Term Notes Payable is a Long-term Liability (Except the Current portion due which is a Current Liability)

Capital is Owners' Equity
