Estate Tax Life Insurance: How Much Coverage Do You Need?

Preserving a substantial estate requires more than investment performance and asset

growth—it requires disciplined planning for taxes, liquidity, and timing. One of the most

significant and often underestimated risks to generational wealth is the estate tax bill due at

death. Without sufficient liquidity, even well-constructed estates can be forced into undesirable outcomes, including the rushed sale of real estate, concentrated investments, or closely held businesses.

Life insurance, when properly structured, is one of the most effective tools available to address this risk. The key question is not whether life insurance is appropriate, but how much coverage is required to protect the estate and preserve long-term intent. Below is a clear, step-by-step framework to determine the appropriate level of coverage for estate tax planning.

1. Start With Your Potential Estate Tax Exposure

The first step in assessing your estate tax exposure is understanding the federal and state

estate tax landscape as it stands for 2026.

Federal estate tax (U.S.):

• In 2026, the federal basic exclusion amount is $15 million per person. This is up from

$13.99 million for 2025.

• For married couples with portability and proper planning, the combined federal exclusion

can be $30,000,000.

• Amounts above the federal exclusion are subject to the estate tax, with a top tax rate of 40% on the taxable amount.

State estate or inheritance taxes:

Several states impose their own estate or inheritance taxes with much lower exemption

thresholds (often in the $1–$5 million range), creating additional potential exposure independent of federal rules. These state-level obligations must be analyzed separately as part of a comprehensive estate plan.

2. Calculate Your Taxable Estate

Next, estimate the total value of your estate, including:

• Real estate

• Investment and brokerage accounts

• Retirement accounts

• Business and private equity interests

• Life insurance you personally own

• Personal property and collectibles
  

Taxable Estate = Total Estate Value – Available Exemptions

This figure—not net worth alone—is what ultimately determines your estate tax liability.

3. Estimate the Estate Tax Bill

A simplified way to estimate potential estate taxes is:

Estate Tax = Taxable Estate × Applicable Tax Rate

Example:

• Total estate value: $18 million

• Federal basic exclusion: $15 million

• Taxable estate: $3 million

• Estimated federal tax at 40%: $1.2 million

This $1.2 million estimate becomes the baseline target for life insurance coverage intended to provide liquidity for federal estate tax obligations. If state estate taxes apply, those should be calculated separately and may increase the total liquidity need.

4. Define What the Insurance Is Meant to Accomplish

Life insurance in estate planning is not about “cheaply paying taxes.

” It is about providing immediate liquidity at the precise moment it is needed.Common objectives include:

• Paying federal and state estate taxes

• Preventing forced sales of real estate or operating businesses

• Equalizing inheritances among heirs

• Covering legal, accounting, and estate settlement costs

Practical planning guideline:

Many estate planners recommend coverage equal to 100–120% of the estimated estate tax

liability. The additional margin accounts for valuation fluctuations, administrative expenses, and unforeseen costs.

100% coverage may be sufficient for more stable estates with adequate liquidity.

120% coverage provides a margin of safety, particularly when:

• A significant portion of wealth is illiquid

• Asset values may fluctuate

• Liquidity flexibility for heirs is a priority

Coverage below 100% introduces avoidable risk and undermines the purpose of the strategy.

5. Ownership Matters (Critically Important)

If life insurance is owned personally, the death benefit may be included in your taxable estate, negating much of its intended benefit. The preferred structure is an Irrevocable Life Insurance Trust (ILIT).

An ILIT:

• Owns the policy

• Keeps the death benefit outside of the taxable estate

• Provides liquidity to heirs or the estate to satisfy tax obligations

• Proper ownership and administration are essential for the strategy to work as intended.

6. The Most Common Insurance Type Used

For estate tax planning, the focus is typically on permanent life insurance, such as:

• Whole life

• Universal life

These policies are designed to last for life and emphasize a reliable, long-term death benefit

rather than investment performance.

7. A Simple Coverage Estimator

To frame your planning discussion, consider:

• What will my estate be worth at death?

• What exemption is likely to apply at that time?

• What federal and state estate taxes may be due?

• How much liquidity will my heirs already have?

Estimated coverage needed = Estimated estate taxes – Existing liquid assets

Planning for Certainty in an Uncertain Environment

Estate tax life insurance is ultimately about control, liquidity, and certainty. For estates that

exceed current or future exemptions, include illiquid assets, or face state-level estate taxes,

properly structured life insurance can be one of the most effective tools available.

Work closely with your estate planning attorney to determine the appropriate amount of

coverage and ownership structure. Studemont Group will coordinate with your legal and

advisory team to design and implement an integrated ILIT strategy aligned with your broader
