What Is the Estate Tax and How Does It Work?

The estate tax, often called the "death tax," is a federal levy on the transfer of wealth from a deceased person to their heirs. Based on my experience as a CPA working with high-net-worth families, this tax applies only to the portion of an estate exceeding the exemption threshold, which is $12.92 million per individual in 2024 ($25.84 million for married couples).

The IRS taxes the gross estate, which includes all property, cash, investments, real estate, life insurance proceeds, retirement accounts, and business interests. According to IRS data from 2022, only 2,064 estate tax returns were filed for 2020 deaths, representing just 0.2% of all deaths that year. The average effective tax rate on taxable estates was 16.5%, with total revenue collected reaching $13.6 billion.

The estate tax calculation follows this general formula:

• Gross estate value
• Minus deductions (marital deduction, charitable deductions, debts, funeral expenses)
• Minus applicable exemption amount ($12.92 million in 2024)
• Equals taxable estate
• Apply graduated tax rates (18% to 40%)

What Is the Difference Between Estate Tax and Inheritance Tax?

This is one of the most common questions I encounter from clients. While often confused, estate tax and inheritance tax are fundamentally different.

Feature	Estate Tax	Inheritance Tax
Who pays	The estate itself	The individual heirs
Federal level	Yes, applies nationwide	No federal tax exists
State level	12 states + DC	6 states
Exemption	$12.92 million (federal)	Varies by state (often lower)
Rates	18%-40% federal	0%-20% state
Who is taxed	The deceased's wealth	What each heir receives

For example, if a New Jersey resident dies with a $15 million estate, the estate pays federal estate tax on the amount above $12.92 million. Additionally, New Jersey imposes its own estate tax on estates above $675,000 (as of 2024). Meanwhile, if that same resident leaves $500,000 to a sibling, the sibling may owe New Jersey inheritance tax at rates up to 16%.

Based on data from the Tax Foundation, in 2024, six states impose inheritance taxes: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Unlike estate taxes, inheritance taxes depend on the relationship between the deceased and the heir. Spouses are generally exempt, while distant relatives or non-relatives face the highest rates.

What Are the Current Federal Estate Tax Exemption and Rates?

As of 2024, the federal estate tax exemption stands at $12.92 million per individual, indexed for inflation. For married couples, the combined exemption is $25.84 million through portability (discussed below). This exemption is historically high due to the Tax Cuts and Jobs Act (TCJA) of 2017, which doubled the exemption from $5.49 million in 2017.

However, a critical planning consideration is that the TCJA is scheduled to sunset on December 31, 2025. Unless Congress acts, the exemption will revert to approximately $6.8 million per individual (adjusted for inflation) in 2026. This represents a 47% reduction from current levels.

The federal estate tax rates are progressive, ranging from 18% on the first $10,000 of taxable estate to 40% on amounts exceeding $1 million. The marginal rate structure is as follows:

Taxable Estate Amount	Tax Rate	Cumulative Tax
$0 - $10,000	18%	$0 - $1,800
$10,001 - $20,000	20%	$1,800 - $3,800
$20,001 - $40,000	22%	$3,800 - $8,200
$40,001 - $60,000	24%	$8,200 - $13,000
$60,001 - $80,000	26%	$13,000 - $18,200
$80,001 - $100,000	28%	$18,200 - $23,800
$100,001 - $150,000	30%	$23,800 - $38,800
$150,001 - $250,000	32%	$38,800 - $70,800
$250,001 - $500,000	34%	$70,800 - $155,800
$500,001 - $750,000	37%	$155,800 - $248,300
$750,001 - $1,000,000	39%	$248,300 - $345,800
Over $1,000,000	40%	$345,800 + 40% of excess

In practice, most taxable estates pay the top 40% rate because the exemption is so high. According to IRS statistics, the average effective tax rate on taxable estates in 2020 was 16.5%, but this reflects the graduated rates only for estates just above the exemption.

Which States Have Their Own Estate or Inheritance Taxes?

Beyond the federal estate tax, 12 states and the District of Columbia impose their own estate taxes, and 6 states impose inheritance taxes. Some states, like Maryland, impose both.

States with Estate Taxes (2024):

• Connecticut: $9.1 million exemption, 12% top rate
• District of Columbia: $4.4 million exemption, 16% top rate
• Hawaii: $5.49 million exemption, 20% top rate
• Illinois: $4 million exemption, 16% top rate
• Maine: $6.8 million exemption, 20% top rate
• Maryland: $5 million exemption, 16% top rate
• Massachusetts: $1 million exemption, 16% top rate
• Minnesota: $3 million exemption, 16% top rate
• New York: $6.58 million exemption, 16% top rate
• Oregon: $1 million exemption, 16% top rate
• Rhode Island: $1.7 million exemption, 16% top rate
• Vermont: $5 million exemption, 16% top rate
• Washington: $2.193 million exemption, 20% top rate

States with Inheritance Taxes (2024):

• Iowa: $25,000 exemption, rates 2%-6%
• Kentucky: $1,000 exemption, rates 4%-16%
• Maryland: $1,000 exemption, rates 0%-10%
• Nebraska: $10,000 exemption, rates 1%-18%
• New Jersey: $0 exemption, rates 0%-16%
• Pennsylvania: $3,500 exemption, rates 0%-15%

A critical distinction: state estate taxes are generally not deductible on the federal estate tax return for decedents dying after 2004. This means a Massachusetts resident with a $5 million estate could owe $640,000 in state estate tax on top of any federal tax.

What Are the Most Effective Strategies to Minimize Estate Tax?

Based on my 15 years of experience advising clients on wealth transfer planning, the following strategies are most effective for minimizing estate tax exposure:

1. Annual Gift Exclusion

The most straightforward strategy is using the annual gift tax exclusion, which allows you to give $18,000 per recipient per year in 2024 (up from $17,000 in 2023). A married couple can give $36,000 per recipient. Over 10 years, a couple with 3 children and 6 grandchildren could transfer $3.24 million tax-free.

2. Lifetime Gift Exemption

Beyond annual exclusions, you can use your $12.92 million lifetime gift exemption to transfer assets now rather than at death. This removes future appreciation from your estate. For example, if you gift $5 million of stock that grows to $15 million by your death, you've saved estate tax on $10 million of appreciation.

3. Irrevocable Life Insurance Trust (ILIT)

An ILIT removes life insurance proceeds from your taxable estate. By having the trust own the policy, the $5 million death benefit you intended for your children avoids estate tax entirely. The trust pays premiums using your annual gift exclusions.

4. Grantor Retained Annuity Trust (GRAT)

A GRAT allows you to transfer appreciating assets to beneficiaries with minimal gift tax cost. You contribute assets to the trust and receive an annuity payment for a term of years. If the assets outperform the IRS assumed interest rate (4.6% in May 2024), the excess passes to beneficiaries tax-free. This strategy was famously used by Facebook founder Mark Zuckerberg to shelter billions.

5. Charitable Remainder Trust (CRT)

A CRT provides income for life or a term of years, with the remainder going to charity. You receive an immediate charitable deduction, and the trust can sell appreciated assets without capital gains tax. The trust pays you income, and the charity receives the remainder estate-tax-free.

6. Family Limited Partnership (FLP)

An FLP allows you to centralize family assets and transfer limited partnership interests to heirs at discounted values. Valuation discounts of 20-40% are common due to lack of marketability and minority interest. A $10 million asset might be valued at $7 million for gift tax purposes.

7. Spousal Lifetime Access Trust (SLAT)

A SLAT allows one spouse to gift assets to a trust for the benefit of the other spouse and children. The trust is designed to be estate-tax-free at both spouses' deaths while providing the surviving spouse with access to trust assets.

How Does Portability Work for Married Couples?

Portability is one of the most important estate planning tools for married couples, introduced by the Tax Relief Act of 2010. It allows a surviving spouse to use the deceased spouse's unused estate tax exemption.

Here's how it works: If one spouse dies in 2024 with a $12.92 million exemption but only uses $2 million during life or at death, the remaining $10.92 million exemption is "portable" to the surviving spouse. The surviving spouse can then use their own $12.92 million exemption plus the deceased spouse's $10.92 million, for a total of $23.84 million.

To elect portability, the executor must file IRS Form 706 (Estate Tax Return) within 9 months of death, even if no tax is due. The deadline can be extended by 6 months with Form 4768. According to IRS data, over 60% of estate tax returns filed in 2020 were portability-only returns, meaning no tax was owed but the election was needed.

Important portability considerations:

• Portability is only available for the last deceased spouse's exemption
• It does not apply to state estate taxes (only federal)
• It does not apply to GST (Generation-Skipping Transfer) tax exemption
• The exemption amount is fixed at the first spouse's death date

For example, if Husband dies in 2024 with $12.92 million exemption and Wife dies in 2026 when the exemption has dropped to $6.8 million, Wife can use her $6.8 million plus Husband's $12.92 million, for a total of $19.72 million.

What Happens If You Exceed the Estate Tax Exemption?

If your estate exceeds the exemption amount, the excess is taxed at rates up to 40%. But the consequences go beyond just the tax bill. Here's what happens:

Filing Requirements

You must file Form 706 within 9 months of death (extendable to 15 months). The return must include a complete inventory of all assets, valuations, deductions, and elections. Failure to file can result in penalties of 5% per month up to 25% of the tax due.

Payment Options

The estate tax is due within 9 months of death. However, for estates consisting primarily of closely held businesses, Section 6166 allows you to defer payment for up to 14 years. You pay only interest for the first 5 years, then principal plus interest over the next 10 years. The interest rate on the first $1.64 million of tax is 2% (as of 2024), while the remainder is at 45% of the regular IRS rate.

Liquidity Concerns

Many estates face liquidity crises because assets are illiquid—real estate, business interests, collectibles. The estate may need to sell assets at fire-sale prices to pay the tax. This is why life insurance is often recommended as a liquidity source.

Penalties for Underpayment

If the IRS determines your estate was undervalued, you face penalties of 20% for negligence and 40% for fraud. Appraisals from qualified professionals are essential.

Key Takeaways

1. The federal estate tax exemption is $12.92 million per individual in 2024, but this is scheduled to drop to approximately $6.8 million in 2026. Plan now to take advantage of the higher exemption.

2. Only 0.2% of estates pay federal estate tax, but state estate taxes affect many more. Check your state's exemption, which can be as low as $1 million in Massachusetts and Oregon.

3. Portability allows married couples to combine exemptions, but you must file Form 706 to elect it. This is critical even if no tax is due.

4. Annual gift exclusions ($18,000 per recipient in 2024) are the easiest way to reduce your estate. A couple can transfer $36,000 per person per year tax-free.

5. Irrevocable trusts like ILITs, GRATs, and SLATs are powerful tools for wealthy families. They remove assets from your estate while providing income or control.

6. The 2026 sunset requires immediate action. If you have a net worth over $5 million, you should consider making gifts before the exemption drops.

Frequently Asked Questions

Question: What is the difference between estate tax and inheritance tax?
Estate tax is paid by the estate itself before assets are distributed to heirs. Inheritance tax is paid by individual heirs based on what they receive. The federal government imposes only estate tax, while six states impose inheritance tax.

Question: How much can I inherit without paying tax?
At the federal level, you can inherit up to $12.92 million from a single person in 2024 without the estate paying tax. However, if you inherit from someone who died with an estate under the exemption, you owe nothing. State exemptions vary widely, from $1 million in Massachusetts to $9.1 million in Connecticut.

Question: Does life insurance count toward the estate tax?
Yes, if you own the policy, the death benefit is included in your taxable estate. This is why many wealthy individuals use an Irrevocable Life Insurance Trust (ILIT) to own the policy, removing the death benefit from their estate.

Question: Can I avoid estate tax by giving away my assets before death?
Yes, but you must use your lifetime gift exemption ($12.92 million per person in 2024) and annual exclusions ($18,000 per recipient). Gifts beyond these amounts use up your exemption and may trigger gift tax.

Question: What happens to the estate tax exemption in 2026?
Unless Congress acts, the exemption will revert to approximately $6.8 million per person (adjusted for inflation) on January 1, 2026. This represents a 47% reduction from current levels. Planning now is essential.

Question: Do I need to file an estate tax return if no tax is due?
Yes, if you want to elect portability for a deceased spouse. You must file Form 706 within 9 months of death to preserve the unused exemption. Even if no tax is owed, this election can save millions in future taxes.

Question: What is the GST tax and how does it differ from estate tax?
The Generation-Skipping Transfer (GST) tax applies to transfers to grandchildren or unrelated beneficiaries more than 37.5 years younger. It has the same $12.92 million exemption and 40% rate as the estate tax, but it's an additional tax on top of estate tax.

Question: Can a trust help me avoid state estate taxes?
Yes, certain trusts can help. For example, a Qualified Terminable Interest Property (QTIP) trust can defer state estate tax until the surviving spouse's death. However, trust planning must consider both federal and state rules, which vary significantly.
