Even though a business has some of the aspects of agency it shall not be so regarded unless it is a true agency. Without prejudice to the generality of the foregoing, the reimbursement by one person of the amount of costs incurred by another constitutes gross income to the latter, unless the person making the reimbursement was himself, as principal liable in that amount to the third party who furnished the property, services and the like for which the costs were incurred.
The old law provided that the reimbursement exemption was applicable to amounts repaid to an agent (taxpayer) by its principal that reimburse the agent for costs that the principal was liable for. Under the current statute, and these rules an agency relationship is not required to qualify for the reimbursement exemption; although the reimbursement exemption may apply where there is an agency relationship.
Some of the principles and examples in these rules are drawn from Taxability of Reimbursement, 1968.
