Tax on loyalty rewards

If a company gave an employee the right to use the company credit card for purchases at specific brands stores. If the employee has a loyalty card, and the company credit card purchases resulted in him earning a significant amount of reward points, what would the income tax implications be for the employee and their employer.

There would be know real tax implications, more of a fortuitous gain and not taxable.

Could you explain why?

There is currently no tax liability on customer loyalty card benefits (points). Should SARS start imposing tax on it, they will definitely inform members of this.
