Computation of partner's share: prescribed deductions and adjustments determine individual taxable share and its apportionment. Computation of a partner's or member's share requires deducting interest, salary, commission or other remuneration (and, where applicable, tax payable by the firm) from the entity's total income, apportioning the balance among partners/members, adding paid remuneration back if the apportioned amount is a profit, or adjusting it against an apportioned loss. The computed share is apportioned under the same heads of income as the entity. Interest on capital borrowed for investment in the entity is deductible from the individual's share for computing business income, and partner/member losses in specified firms may be set off or carried forward.
