All the amounts received by Billy, are during the course of business, and are related to the damages caused to business, and to him personally, and under tax these all amounts are tax free:
Amount received for personal injury of $100,000 is tax free as is related to expense of his personal recovery.
The amount of $50,000 and $15,000 though received from different sources but is for the same purpose of loss of income and destruction caused to business.
Whereas, amber is an employee, she is not the owner and therefore, all of the benefits received from her workplace are taxable.
As the policy was purchased by the employer and therefore, any amount received from such policy by amber will be taxable as a perquisite received from employer.
