Credit card perquisite valuation treats employer-paid personal expenses as taxable, while wholly official use remains non-taxable with proper documentation. Credit card expenses paid or reimbursed by an employer may be taxable as a perquisite when used for personal or household purposes. Taxable value includes the employer-borne expenses, together with membership and annual fees, less any amount recovered from the employee. No value arises for expenses incurred wholly and exclusively for official purposes if the employer maintains complete expenditure details and issues a certificate confirming official use.
