Final answer:
Lump-sum payments from a life insurance policy to a primary beneficiary are generally received income tax free.
Step-by-step explanation:
The correct statement regarding the tax treatment of a lump-sum payment paid to a life insurance policy's primary beneficiary is D. All proceeds are income tax free in the year they are received. Generally, the death benefit of a life insurance policy is paid out to beneficiaries tax-free. Instead of being taxed on the amount they receive from the policy, beneficiaries usually receive the full death benefit without having to pay income tax on it.
