Estate tax liquidity is one of the most frequent — and solvable — problems for high-net-worth (HNW) families. In this article we analyze practical scenarios where life insurance funds estate tax liabilities, show cost trade-offs across product types and carriers, and quantify the net-family-wealth impact for U.S.-based estates (with focused examples for New York City, San Francisco, and Miami). We also link to deeper modeling and trust-integration topics for HNW planning.
Why life insurance is used to pay estate taxes
- Immediate liquidity at death — life insurance proceeds paid in cash can prevent forced asset sales (real estate, family businesses, concentrated stock).
- Predictability — insurance can be sized precisely to match projected tax liabilities.
- Flexibility of ownership structures — policies can be owned by an ILIT or other irrevocable trust to remove proceeds from the insured’s taxable estate.
Key federal background (2024):
- Federal estate & gift tax exemption: $13.61 million per individual (indexed annually).
- Top federal estate tax rate: 40% on taxable estates above the exemption.

Typical scenarios where insurance is deployed
Scenario A — Single decedent with concentrated illiquid assets (e.g., NYC real estate)
- Estate value: $25 million (primarily real estate and private holdings).
- Federal taxable estate after exemption ($13.61M): $11.39M → estimated federal tax ≈ $4.556M.
- Solution: Buy a life policy (or policies) to cover $4.6M of tax liability; structure ownership in an ILIT so proceeds are out of the estate.
Scenario B — Married couple who want portability protection and asset preservation (San Francisco tech founder + spouse)
- Portability doubles usable exemption only if the deceased spouse’s executor files an estate tax return to elect portability. But portability can be risky with state-level triggers or future legislative changes.
- Solution: Survivorship (second-to-die) life insurance owned by an ILIT — typically more cost-efficient for couples who want a single death benefit to fund taxes at second death while minimizing premium outlay compared to two single-life GUL policies.
Scenario C — Multi-state families (e.g., residence in Florida, vacation properties in New York and Massachusetts)
- Even if the decedent’s state of legal residence (Florida) has no estate tax, properties located in NY or MA may trigger state-level estate taxation or other transfer taxes.
- Solution: Blend life insurance sized to cover expected federal and state liabilities, factoring in state-level thresholds and credits.

Product choices and cost comparisons
Common life-insurance vehicles used for estate tax funding:
- Term life (rare for permanent estate tax funding unless timed for a near-term liquidity need)
- Guaranteed Universal Life (GUL) — provides long-term guaranteed death benefit with lower cash value growth; popular to lock in a death benefit cost-effectively
- Survivorship/Second-to-die (S2D) permanent policies — efficient for married-couple estate-tax funding
- Traditional Whole Life — higher cost but strong guarantees and dividends (with certain carriers)
Below is an illustrative cost comparison for a hypothetical required death benefit of $5,000,000 for a U.S. insured male, nonsmoker. Quotes are illustrative ranges (actual pricing depends on underwriting, health, amount, and product design). Sources include insurer product pages and market aggregators such as Policygenius.
| Product type | Typical buyer profile | Example annual premium (illustrative ranges) | Key trade-offs |
|---|---|---|---|
| 20-year Term | 40–55-year-old borrower seeking short-term liquidity | $1,800–$5,000/yr for $5M (younger buyers cheaper) — sample aggregator ranges | Low cost but expires; not for permanent estate-tax exposure |
| Guaranteed Universal Life (GUL) | 55–75-year-old seeking permanent coverage | $20,000–$60,000/yr for $5M (varies by age/sex/underwriting) | Permanent, cost-efficient vs whole life, limited cash accumulation |
| Survivorship GUL / S2D | Married couples wanting coverage at second death | $12,000–$45,000/yr for $5M S2D (couple ages and health affect pricing) | Lower than two single-life GULs; pays at second death |
| Whole Life (high-dividend carriers) | Buyers prioritizing guarantees and dividends | $30,000–$100,000+/yr for $5M or single premium large buys | Highest cost, cash accumulation, loans available |

Mentioned carriers (examples used widely in HNW planning):
- New York Life — strong whole-life and GUL product suites with high underwriting standards.
- Northwestern Mutual — large dividend-paying whole life, agent-centric.
- Prudential — large presence in term, universal, and estate planning solutions.
- Haven Life / Ladder (aggregators) — commonly used for competitive term quotes via online platforms.

Example calculation: Net-family-wealth impact (New York City family, single decedent)
Assumptions:
- Gross estate: $25,000,000
- Federal exemption: $13,610,000
- Federal taxable estate: $11,390,000 → federal tax ≈ $4,556,000 (40%)
- No state estate tax assumed for this example (add state taxes if applicable)
- Option A: Sell assets to pay tax (liquidity cost, potential 15–25% market friction)
- Option B: Buy a $4.6M death benefit (ILIT-owned GUL), annual premium assumed $35,000 (illustrative, 60-year-old insured)
Net-family-wealth comparison (simplified):
- Without insurance: Estate pays $4.556M in taxes; if forced sale reduces value by 20% due to fire sale/discounts, additional loss ≈ $900k → total family loss ≈ $5.456M.
- With insurance: Family receives $4.6M tax liquidity; pay cumulative premiums until death (if life expectancy 20 years and no cash surrender: 20 × $35k = $700k). Net liquidity available to pay taxes: $4.6M – $700k = $3.9M (premium estimate excludes time value adjustments and policy costs). After paying $4.556M tax, shortfall would be covered by remaining liquid assets; but primary benefit is avoiding asset fire sales and market disruption.
This simplified example shows the trade-off: paying premiums to preserve illiquid estate value often increases net-family-wealth versus forced sales, especially when the forced-sale haircut is large or a business is involved.
Practical considerations and pitfalls
- Ownership matters: If the insured owns the policy directly, proceeds may be includable in the estate. Use an ILIT or properly structured trust to keep proceeds out.
- Medical underwriting and insurability: Older or impaired lives face much higher pricing; advanced underwriting can materially change economics.
- State tax complexity: Some states (e.g., New York, Massachusetts) have lower exemption thresholds or estate tax rules that make insurance planning more urgent. (See state-level detail at Tax Foundation.)
- Audit risk and transfer-for-value: Improper transfers or retained incidents of ownership can trigger inclusion or adverse tax treatment. Work with counsel.

Action checklist for advisors and trustees (U.S. focus)
- Model projected federal and state estate taxes using current exemption figures and potential future appreciation.
- Evaluate insurability and product types: term (short gap), GUL (permanent), S2D (married couples).
- Price policies from multiple carriers (e.g., New York Life, Northwestern Mutual, Prudential) and aggregators (Policygenius, Haven Life) to benchmark premiums.
- Use an ILIT or other properly drafted trust; coordinate with estate counsel to avoid inclusion.
- Stress-test outcomes under mortality timing, market declines, and potential changes in estate-tax law.

For HNW families in New York City, San Francisco, or Miami, life insurance — properly owned and structured — is one of the most effective, predictable ways to fund estate taxes while preserving business and real-estate continuity. Work with specialized life-insurance underwriters, estate counsel, and tax advisors to design ILIT ownership, choose the right product (GUL vs survivorship), and run mortality- and market-based stress tests before implementation.
