Answer:
LLC liabilities are included as part of member's tax basis while S corporation liabilities are not.
Tax rules favors LLCs.
Step-by-step explanation:
LLC liabilities are included as part of a member's tax basis while S corporation liabilities are not included in an S corporation shareholder's tax basis other than loans from the shareholders.
This distinction is important because the amount of loss a member or shareholder may deduct is limited to his or her tax basis in either his or her LLC interest or shares. Thus in this particular regard Tax rules favors LLCs.
