A beneficiary is the person or entity designated to receive policy proceeds — such as a life insurance death benefit or retirement account balance — upon the policyholder's death or a triggering event. Beneficiary designations typically override wills and bypass probate.
Designating a beneficiary is one of the most consequential financial decisions a person makes, yet it is often set at account opening and never revisited. On life insurance policies, the primary beneficiary receives the death benefit directly; if the primary predeceases the insured, the contingent (secondary) beneficiary collects instead. Financial accounts — IRAs, 401(k)s, annuities, and some bank accounts (via payable-on-death or transfer-on-death designations) — also use beneficiary designations. The IRS and DOL regulate beneficiary rules differently across account types; notably, the SECURE Act 2.0 changed inherited IRA distribution rules for most non-spouse beneficiaries. Because beneficiary designations supersede a will, outdated designations are a leading source of estate disputes. Periodic review — especially after marriage, divorce, birth of a child, or the death of a named beneficiary — is strongly recommended. Some states have automatic-revocation laws that invalidate an ex-spouse designation upon divorce, but federal ERISA plans (like 401(k)s) are not subject to state law and may not have this protection.
Yes. You can split proceeds among multiple primary beneficiaries by percentage. Each can also have their own contingent beneficiary. Make sure percentages sum to 100%.
Proceeds go to your estate, pass through probate, and are distributed per your will (or state intestacy law if no will exists). This delays distribution and can increase estate costs.
Generally no — life insurance death benefits paid to individuals are income-tax-free under IRC §101(a). Estate tax may apply in very large estates; consult a tax professional for your situation.
