How is the death benefit from a life insurance policy generally taxed to the beneficiary?

THE INCOME TAX-FREE DEATH BENEFIT is the foundational tax advantage of life insurance and one of the most tested topics on licensing exams. IRC SECTION 101(a): Life insurance death benefits paid by reason of the death of the insured are EXCLUDED from the beneficiary's gross income (not taxable). This applies: Regardless of the death benefit amount; Whether paid to an individual or a corporation (e.g., key person insurance); Regardless of who owns the policy (insured, spouse, corporation, trust); For both term and permanent policies. EXCEPTIONS — SITUATIONS WHERE THE BENEFIT MAY BE TAXABLE: (1) INTEREST — if the benefit is left with the insurer (settlement option) rather than paid as a lump sum, and interest accumulates, the INTEREST portion is taxable ordinary income (the principal remains tax-free); (2) TRANSFER FOR VALUE RULE — if the policy is sold or transferred for valuable consideration to a non-exempt party, the death benefit becomes partially taxable (the gain over the amount paid is taxable); exceptions to transfer for value include transfers to the insured, the insured's partner, or a corporation the insured is an officer of; (3) ESTATE TAXES — the death benefit may be included in the insured's ESTATE for estate tax purposes if the insured had 'incidents of ownership' at death; for large estates (over the federal estate tax exemption), this can create estate taxes though not income taxes; placing the policy in an irrevocable life insurance trust (ILIT) removes it from the estate. PRACTICAL NOTE: Advisors emphasize this tax-free benefit when illustrating the cost of life insurance relative to other financial products.
