Answer:
Life insurance benefits are not taxable, so Khalid would keep the full $100,000 regardless of his 37% marginal tax bracket.
Step-by-step explanation:
Khalid does not need to pay any taxes on the $100,000 in life insurance benefits he receives, as life insurance payouts are generally not considered taxable income. Therefore, if Khalid is in the 37% marginal tax bracket, it does not affect the life insurance benefit. The entirety of the $100,000 benefit would be left for Khalid after-tax.
