A reimbursement for a legitimate business expense is a repayment to an employee for money they spent out-of-pocket on behalf of the company. Since this payment is not a form of compensation or remuneration for services rendered but rather a repayment of a debt, it is not considered income. Therefore, the amount is not subject to income tax, Canada Pension Plan (CPP) contributions, or Employment Insurance (EI) premiums. The reimbursement simply makes the employee "whole" for the business-related cost they incurred.

A. The payment is not considered earnings from employment, so it is not pensionable under the Canada Pension Plan.

B. As the payment is a repayment for a business expense and not remuneration, it is not considered taxable income.

D. A retiring allowance is a specific payment made upon termination or retirement in recognition of service, which is unrelated to expense reimbursement.
