Overview
Life insurance is a commonly used tool in wealth transfer because it delivers immediate cash at death that beneficiaries can use to pay estate taxes, funeral costs, debts, or to equalize inheritances among heirs. Unlike many estate assets (real estate, private business interests, or retirement plans), life insurance proceeds are paid quickly and are usually income‑tax free to the beneficiary under IRC §101(a). That cash liquidity can prevent forced sales of family businesses or the family home and make distributions fairer between beneficiaries with unequal holdings.
In my practice working with families and business owners, the most successful uses of life insurance for wealth transfer combine product selection (term vs. permanent), ownership and beneficiary design, and trust structure to control tax inclusion and distribution timing.
Why use life insurance in estate planning?
- Liquidity: Death benefits arrive within days or weeks and can be used immediately to pay estate taxes, final expenses, loans, or buy out a business partner.
- Tax treatment: Death proceeds are generally excluded from the beneficiary’s gross income (IRC §101(a)). However, proceeds may be included in the decedent’s gross estate for estate tax purposes if the decedent retained incidents of ownership (IRC §2042).
- Equalization: Policies allow heirs to receive equal value even when assets are illiquid or intended to stay with specific family members (for example, a closely held business or a farmland parcel).
How the mechanics work
At death, the insurer pays the named beneficiary the policy’s death benefit. Families use that cash to:
- Pay estate taxes and estate administration costs.
- Repay mortgages or outstanding debts associated with the estate.
- Provide cash bequests to heirs who don’t inherit specific assets (equalization).
- Fund buy‑sell agreements for businesses.
A simple illustrative scenario: assume a gross estate exposes the family to a significant estate tax liability. Rather than selling a business interest to raise cash, the estate receives a life insurance death benefit that covers the tax bill. That preserves the business for heirs who will operate it.
Ownership, trusts, and common tax traps
Ownership and control determine whether life insurance proceeds are included in the decedent’s estate. Key rules and planning levers:
-
Inclusion for incidents of ownership (IRC §2042): If the insured owns the policy or retains incidents of ownership (the right to change beneficiary, borrow the cash value, surrender the policy), the death benefit typically is includible in the insured’s gross estate for estate tax purposes.
-
Transfers and the three‑year lookback (IRC §2035): If you transfer a policy to someone else (or to a trust) and die within three years of the transfer, the proceeds can be pulled back into your gross estate under the three‑year rule. That makes late transfers ineffective for removing proceeds from the estate.
-
Irrevocable Life Insurance Trusts (ILITs): An ILIT that owns the policy and is properly structured and funded can generally keep the proceeds out of the insured’s gross estate, provide creditor protection for proceeds, and allow the trustee to control distributions. Funding strategies (gifts to the trust, Crummey powers) and correct trustee ownership are essential.
-
Transfer for value rule (IRC §101(a) exception): If a life insurance policy is sold or transferred for value, the tax treatment of the death benefit can change. Work with counsel to avoid inadvertent transfer‑for‑value problems when assigning or selling policies.
Types of policies and when to use them
- Term life insurance: Provides a large death benefit for relatively low premiums for a definite period. Good for bridging a known liability (such as a mortgage or temporary estate tax exposure while other planning matures).
- Permanent life insurance (whole life, universal life): Has cash value and can be used for longer‑term planning, estate liquidity, or funding long‑term trusts. Premiums are higher, but permanent policies can be useful where estate tax exposure is long‑term or for multigenerational planning.
- Survivorship (second‑to‑die) life insurance: Covers two lives and pays on the second death. Often used to fund estate taxes for married couples because it is less expensive than two separate policies and is timed to the second death when estate tax liability typically becomes due.
Sample planning use cases (realistic examples)
-
Equalizing inheritances: A parent wants a child who runs the family business to retain the business while leaving equivalent value to the other child. The parent purchases a life policy sized to create a cash bequest to the non‑operating sibling. The policy is owned by an ILIT so proceeds pass to heirs as intended rather than into the taxable estate.
-
Funding estate taxes on illiquid assets: A farm or private business represents 80% of an estate’s value. A life policy sized to anticipated estate tax exposure prevents the forced sale of the farm at probate.
-
Business continuity: A buy‑sell agreement funded with life insurance provides the surviving owners with cash to buy the deceased owner’s interest from the estate, preventing outside heirs from interfering.
(In my experience, couples who pair a second‑to‑die policy with a properly drafted ILIT avoid most of the common ownership pitfalls while keeping premiums affordable.)
Estimating how much insurance you need
A practical approach to sizing a policy:
- Estimate gross estate value (include real estate, business interests, retirement accounts, life insurance you own, and other assets).
- Subtract the available estate tax exemption and allowable deductions to reach a preliminary taxable estate. (The federal exclusion is adjusted annually — see the IRS for the current amount.)
- Apply a conservative tax rate (tax rates can reach the top federal estate tax rate, historically up to 40%) to estimate the potential estate tax liability.
- Add a buffer for administration costs, state estate taxes, and other debts.
Note: State estate or inheritance taxes vary by state and can apply at much lower thresholds than the federal exemption. Include state exposure in your calculation.
Common mistakes and how to avoid them
- Owning the policy personally without understanding estate inclusion. Solution: consider an ILIT or review ownership details with counsel.
- Transferring a policy late in life without accounting for the three‑year lookback. Solution: transfer early or use other planning methods to remove proceeds from the estate.
- Ignoring state taxes and the portability election. Solution: check your state rules and, when applicable, file a timely federal estate tax return to elect portability (Form 706) to preserve an unused spousal exclusion.
- Overreliance on life insurance as a single solution. Comprehensive estate plans should include wills, trusts, beneficiary designations, and possibly business succession documents.
Practical checklist before buying a policy for estate planning
- Confirm whether the policy will be owned by you, your revocable trust, or an ILIT.
- If using an ILIT, confirm trustee powers, Crummey language (if funding by gifts), and that the grantor does not retain incidents of ownership.
- Run illustrations comparing term, permanent, and survivorship policies for the needed coverage period and premiums.
- Coordinate beneficiary designations with your will and other trusts to avoid unintended results.
- Review existing policies and beneficiary designations, including group coverage from employers that may have different rules.

Final considerations
Life insurance is a powerful and flexible tool for wealth transfer, but its effectiveness depends on product choice, ownership, trust design, and timing. Work with an estate attorney and a qualified financial or insurance advisor to ensure the policy aligns with your tax, legal, and family goals. In my practice, clients who document objectives (liquidity needs, equalization goals, and business continuity) up front and coordinate insurance with trust ownership avoid the most common pitfalls and preserve family legacies more reliably.
