What Is the Difference Between Inheritance Tax and Estate Tax?

The confusion between inheritance tax and estate tax is one of the most common mistakes I see in my practice. Estate tax is paid by the estate itself—the executor files a return and pays the tax from estate assets before distribution. Inheritance tax is paid by the beneficiary—the person receiving the assets files a return and pays tax based on their relationship to the deceased.

Here's the critical distinction: The federal government imposes an estate tax (not an inheritance tax), with a $13.61 million exemption per individual in 2024 (up from $12.92 million in 2023, per IRS Revenue Procedure 2023-34). Only 0.1% of estates—roughly 4,500 out of 3.5 million annual deaths—file a federal estate tax return (IRS Statistics of Income, 2023).

State-level death taxes are far more impactful for middle-class families. According to the Tax Foundation's 2024 analysis, 12 states plus the District of Columbia impose an estate tax, while 6 states impose an inheritance tax. Maryland uniquely imposes both.

Key distinctions you must know:

• Federal estate tax: Applies to estates over $13.61M (2024), rates from 18% to 40%
• State estate tax: Applies to estates over state-specific exemption (range: $1M to $12.92M)
• Inheritance tax: Applies to beneficiaries based on relationship and asset value
• Generation-skipping transfer tax (GST): Additional 40% federal tax on transfers to grandchildren or unrelated beneficiaries more than 37.5 years younger

Actionable steps today:

1. Determine your state of residence's death tax status using the tables below
2. Check if your state has a "cliff" estate tax (where the entire estate becomes taxable once it exceeds the exemption)
3. Review your current estate plan with a CPA who knows your state's specific rules

Which States Have an Inheritance Tax in 2025?

As of January 2025, only six states impose an inheritance tax. This is down from 12 states in 2000, as states have gradually repealed these taxes. Here's the complete list with current rates:

State	Exemption Threshold	Top Rate	Beneficiary Classes	Notes
Iowa	$25,000 (Class C)	15%	3 classes	Phasing out: fully repealed by 2025
Kentucky	$500 (Class A)	16%	3 classes	No exemption for distant relatives
Maryland	$30,000	10%	2 classes	Also has estate tax
Nebraska	$10,000 (Class C)	18%	3 classes	Highest top rate in US
New Jersey	$25,000 (Class C)	16%	4 classes	No tax on Class A beneficiaries
Pennsylvania	$3,500 (Class C)	15%	3 classes	No exemption for siblings

Critical note on Iowa: Iowa's inheritance tax is being phased out under SF 619, signed into law in 2021. The tax rate was reduced by 20% in 2022, 40% in 2023, 60% in 2024, and will be fully repealed effective January 1, 2025. As of this writing, Iowa's inheritance tax is still in effect for 2024 but will be eliminated for deaths occurring after December 31, 2024.

The beneficiary class system explained:

Each state defines classes differently, but the general pattern is:

• Class A (Spouses, parents, children, grandchildren): Usually exempt or taxed at lowest rates
• Class B (Siblings, nieces, nephews, aunts, uncles): Moderate rates
• Class C (All other beneficiaries, including friends and charities): Highest rates

According to the American College of Trust and Estate Counsel (ACTEC) 2024 survey, approximately 68% of inheritance tax revenue comes from Class C beneficiaries—distant relatives and non-relatives who receive assets.

Actionable steps today:

1. Identify which beneficiary class each of your heirs falls into
2. If you live in an inheritance tax state, consider gifting strategies to reduce the taxable estate
3. Review your will or trust to ensure beneficiary designations maximize tax-exempt transfers

How Does Each State's Inheritance Tax Work?

Pennsylvania: The Most Aggressive Inheritance Tax State

Pennsylvania's inheritance tax is the most commonly encountered, affecting approximately 45,000 estates annually (Pennsylvania Department of Revenue, 2023). Rates are:

• 0% to surviving spouse
• 0% to parents (if decedent was under 21)
• 4.5% to direct descendants (children, grandchildren)
• 12% to siblings
• 15% to all other beneficiaries

Real-world case study: Margaret Thompson, a 78-year-old widow from Philadelphia, passed away in 2023 leaving a $1.2 million estate to her two adult children and her brother. Her children received $800,000 (4.5% tax = $36,000), while her brother received $400,000 (12% tax = $48,000). Total inheritance tax: $84,000. If Margaret had left everything to her children, the tax would have been $54,000—a savings of $30,000.

New Jersey: Complex but Beneficiary-Friendly

New Jersey's inheritance tax is unique because Class A beneficiaries (spouses, children, grandchildren, parents) pay zero tax. The tax only applies to:

• Class C (siblings, sons-in-law, daughters-in-law): 11-16%
• Class D (all other beneficiaries): 15-16%

Key exemption: New Jersey exempts the first $25,000 to Class C beneficiaries and the first $25,000 to Class D beneficiaries per beneficiary.

Maryland: The Double Tax Trap

Maryland is the only state with both an inheritance tax AND an estate tax. The inheritance tax rate is a flat 10% on amounts over $30,000 passing to non-exempt beneficiaries. The estate tax applies to estates over $5 million (2024).

Case study: Robert Chen, a Maryland resident, died in 2024 leaving a $6.2 million estate. He left $4 million to his wife (exempt from both taxes), $1 million to his sister (subject to 10% inheritance tax = $100,000), and $1.2 million to his children (inheritance tax exempt but estate tax applies). The estate tax on the $1.2 million over the $5 million exemption: $120,000 (10% state estate tax rate). Total Maryland death taxes: $220,000.

Nebraska: Highest Top Rate

Nebraska imposes an 18% top rate on Class C beneficiaries, the highest in the nation. However, the first $10,000 is exempt for Class C, and Class A beneficiaries (spouses, children, parents) are generally exempt up to $40,000.

Kentucky: Low Exemption, High Impact

Kentucky's inheritance tax has a mere $500 exemption for Class A beneficiaries—meaning virtually every inheritance over $500 to a non-spouse is taxable. For a child inheriting $50,000, the tax would be approximately $2,000 (4% on the first $10,000, 5% on the next $10,000, etc.).

Which States Have an Estate Tax?

As of 2025, 12 states plus the District of Columbia impose an estate tax. These are separate from the federal estate tax and have their own exemption thresholds:

State	Exemption (2024)	Top Rate	Portability	Notes
Connecticut	$12.92M (federal)	12%	Yes	Tied to federal exemption
District of Columbia	$4.2M	16%	No	Indexed for inflation
Hawaii	$5.49M	20%	Yes	Indexed for inflation
Illinois	$4M	16%	No	Not indexed
Maine	$6.41M	12%	No	Indexed for inflation
Maryland	$5M	16%	No	Also has inheritance tax
Massachusetts	$1M	16%	No	Not indexed since 2001
Minnesota	$3M	16%	No	Indexed for inflation
New York	$6.94M	16%	Yes	Indexed for inflation
Oregon	$1M	16%	No	Not indexed
Rhode Island	$1.79M	16%	No	Indexed for inflation
Vermont	$5M	16%	No	Indexed for inflation
Washington	$2.193M	20%	No	Indexed for inflation

Critical insight on "cliff" estate taxes: Six states (Connecticut, Illinois, Maryland, Massachusetts, Minnesota, New York) have a "cliff" provision where if the estate exceeds the exemption by any amount, the entire estate becomes taxable. For example, in Massachusetts, an estate worth $1.1 million would owe estate tax on the full $1.1 million, not just the $100,000 over the $1 million exemption.

According to the Center on Budget and Policy Priorities (2023), state estate taxes generated approximately $6.8 billion in revenue in 2022, with Washington state ($1.2 billion) and New York ($1.1 billion) accounting for one-third of all state death tax revenue.

Actionable steps today:

1. Calculate your current net worth to determine if you're approaching your state's exemption
2. If you're in a "cliff" state, consider lifetime gifting to stay below the threshold
3. Review whether your state allows portability (unused exemption passing to spouse)

How Are Inheritance Taxes Calculated for Beneficiaries?

The calculation varies significantly by state, but here's a standardized methodology using Pennsylvania as our example:

Pennsylvania Inheritance Tax Calculation Example:

Scenario: John Smith dies in 2024, leaving a $750,000 estate:

• $500,000 to his daughter (Class A: 4.5%)
• $150,000 to his sister (Class B: 12%)
• $100,000 to his best friend (Class C: 15%)

Step 1: Determine taxable amounts

• Daughter: $500,000 × 4.5% = $22,500
• Sister: $150,000 × 12% = $18,000
• Friend: $100,000 × 15% = $15,000
• Total inheritance tax: $55,500

Step 2: Apply exemptions

• Pennsylvania offers no exemption for Class A or B beneficiaries
• Class C beneficiaries receive a $3,500 exemption ($100,000 - $3,500 = $96,500 taxable)

Step 3: File and pay

• The executor typically files Form REV-1500 within 9 months of death
• Payment is due with the return
• Late payment penalties: 5% per month up to 25% (Pennsylvania Department of Revenue)

Comparison of inheritance tax on a $100,000 inheritance to a sibling:

State	Tax Rate	Tax Owed	Effective Rate
Pennsylvania	12%	$12,000	12.0%
New Jersey	11-16%	$8,250	8.25%
Maryland	10%	$7,000	7.0%
Nebraska	18%	$16,200	16.2%
Kentucky	16%	$15,500	15.5%
Iowa (2024)	10%	$7,500	7.5%

Actionable steps today:

1. Request a beneficiary-specific calculation from your CPA before making estate decisions
2. Consider disclaiming assets (refusing inheritance) to shift to lower-taxed beneficiaries
3. Review life insurance ownership—properly structured, life insurance proceeds can avoid both inheritance and estate taxes

What Is the Best Strategy to Avoid State Death Taxes?

Based on my experience with hundreds of estate plans, here are the most effective strategies, ranked by impact:

1. Lifetime Gifting (Annual Exclusion)

The IRS allows annual gifts of $18,000 per recipient (2024, up from $17,000 in 2023) without triggering gift tax. For a married couple, that's $36,000 per recipient per year. Over 10 years, a couple could gift $360,000 to a single child tax-free.

Strategy: If you live in Pennsylvania, gifting $360,000 to your daughter over 10 years saves $16,200 in inheritance tax (at 4.5%).

2. Irrevocable Life Insurance Trust (ILIT)

An ILIT removes life insurance proceeds from your taxable estate. According to Vanguard's 2023 estate planning study, ILITs save an average of $47,000 in state death taxes for families in inheritance tax states.

3. Qualified Personal Residence Trust (QPRT)

Transfer your home to a trust while retaining the right to live there for a set number of years. The value of the gift is reduced by the retained interest. For a $1 million home, this can reduce the taxable value by 30-50%.

4. Spousal Portability

In states that allow portability (Connecticut, Hawaii, New York), a surviving spouse can use the deceased spouse's unused exemption. This effectively doubles the exemption for married couples.

5. Move to a No-Tax State

While drastic, moving from Massachusetts (estate tax at $1M) to Florida (no death taxes) can save millions. According to United Van Lines' 2023 National Movers Study, 23% of moves to Florida were motivated by tax considerations.

Actionable steps today:

1. Meet with a CPA to calculate your current death tax exposure
2. Set up annual gifting programs for children and grandchildren
3. Review life insurance ownership and consider an ILIT if you're in a death tax state

How Do Portability and Exemptions Affect State Death Taxes?

Portability—the ability to transfer unused estate tax exemption between spouses—is a federal concept that only some states have adopted. Here's the breakdown:

States with portability (as of 2024):

• Connecticut (tied to federal exemption)
• Hawaii (tied to state exemption)
• New York (tied to state exemption)

States without portability:

• District of Columbia
• Illinois
• Maine
• Maryland
• Massachusetts
• Minnesota
• Oregon
• Rhode Island
• Vermont
• Washington

Why portability matters: In a non-portability state, if one spouse dies with a $5 million estate and the other dies with a $5 million estate, the surviving spouse's estate may owe tax on the full $5 million if the state exemption is $3 million. Without portability, the unused $3 million exemption from the first spouse is lost.

Real-world impact: The Chen family from our earlier Maryland case study could have saved $120,000 in state estate tax if Maryland had portability, by using the first spouse's unused exemption.

Actionable steps today:

1. If you're in a non-portability state, consider a "credit shelter trust" to preserve both spouses' exemptions
2. Review your state's exemption indexing—some states haven't updated exemptions since 2001 (Massachusetts, Oregon)
3. Consider a "clawback" strategy: in cliff states, gifting just enough to stay under the exemption can save 100% of the tax

Frequently Asked Questions

1. Do I have to pay inheritance tax if I live in a different state than the deceased?

Yes. Inheritance tax is based on the deceased's state of residence, not the beneficiary's. If your aunt lived in Pennsylvania and left you assets, you owe Pennsylvania inheritance tax regardless of whether you live in Texas or Florida.

2. Are life insurance proceeds subject to inheritance tax?

It depends. If the beneficiary is an individual, life insurance is generally NOT subject to inheritance tax in most states. However, if the policy is payable to the estate, it becomes part of the probate estate and may be subject to estate tax. In Pennsylvania, life insurance to a named beneficiary is exempt from inheritance tax.

3. What is the federal estate tax exemption for 2025?

The IRS has announced that the 2025 federal estate tax exemption will be $13.99 million per individual (up from $13.61 million in 2024). This is indexed for inflation. However, under current law, the exemption is scheduled to drop to approximately $7 million per individual on January 1, 2026.

4. Can I avoid inheritance tax by giving gifts before death?

Yes, but with limits. The annual gift tax exclusion is $18,000 per recipient (2024). Gifts exceeding this amount count against your lifetime exemption ($13.61 million). However, gifts made within 3 years of death may be "clawed back" into the estate for state death tax purposes in some states.

5. Is there a federal inheritance tax?

No. The United States does not have a federal inheritance tax. The federal government imposes only an estate tax. Inheritance taxes are solely a state-level tax. This is a common misconception—approximately 40% of Americans mistakenly believe there's a federal inheritance tax (Gallup, 2023).

6. How do I file an inheritance tax return?

Each state has its own form and process. Generally, the executor files within 9 months of death. States with inheritance taxes require Form REV-1500 (Pennsylvania), Form IT-100 (New Jersey), Form 001 (Maryland), or equivalent. Late filing penalties range from 5% to 25% of the tax due.

7. What happens if I can't pay the inheritance tax?

Most states offer installment payment plans for hardship cases. Pennsylvania allows up to 10 years of installment payments with interest at 6% per year. New Jersey offers similar arrangements. However, interest accrues from the original due date, so paying early is always better.
