Inheritance tax can feel like a double whammy: someone you care about has died and, on top of that, the taxman may want a slice of what you inherit. Even so, for most people this tax is more of a worry in theory than in practice. It only exists in a handful of places, it often kicks in above relatively generous thresholds, and close family members are frequently exempt or benefit from lower rates.

Understanding exactly what inheritance tax is, how it differs from estate tax, and how it works in different jurisdictions is crucial if you want to protect family wealth, plan your estate, or simply know what happens when you receive an inheritance. In this guide we will walk through the core concepts, look in detail at the U.S. rules (both federal and state), compare them with systems in other countries, and review common planning strategies that can reduce or even eliminate the tax bill in many situations.

What is inheritance tax?

Inheritance tax is a levy charged on the value of money, property or other assets that an individual beneficiary receives from a person who has died. The key point is that the tax obligation typically falls on the beneficiary, not on the deceased’s estate itself. If you inherit, you may have to file a state inheritance tax return and pay the tax from what you receive.

In the United States there is no federal inheritance tax; it exists only at the state level, and as of 2025 just five states impose it: Kentucky, Maryland, Nebraska, New Jersey and Pennsylvania. Iowa previously had an inheritance tax but fully repealed it for deaths on or after January 1, 2025, so inheritances after that date in Iowa are no longer subject to this tax.

Whether you owe inheritance tax depends on several factors: where the decedent lived or owned property, how closely you were related to them, the type of assets involved, and the value you actually receive. In general, the closer your family relationship, the more likely you are to be fully exempt or enjoy higher allowances and lower rates, while distant relatives and unrelated beneficiaries usually face higher tax rates.

It is also important to distinguish between an inheritance tax system and systems that tax inheritances indirectly through capital gains or other income tax rules. Some countries do not impose a separate inheritance tax as such, but instead treat inherited property as capital gains or extraordinary income and tax it under their regular income tax regime.

Inheritance tax vs. estate tax (and capital gains)

People often use the terms “inheritance tax”, “estate tax” and even “death tax” interchangeably, but in law they describe different mechanisms and different taxpayers. Getting this distinction right matters for planning and for understanding which rules apply to a given situation.

Estate tax is charged on the deceased person’s estate as a whole, before assets are distributed to heirs or other beneficiaries. The estate itself is the taxpayer: the executor or personal representative calculates the gross estate (everything the decedent owned or had certain interests in), subtracts allowable deductions such as debts, funeral costs, administration expenses, certain business or farm reductions and transfers to a surviving spouse or charity, and arrives at the taxable estate. The federal estate tax in the U.S. works this way.

Inheritance tax, by contrast, is levied on each recipient’s share; the taxable event is the transfer to the beneficiary. Under an inheritance tax regime, your personal liability is based on the amount you receive and on your relationship to the deceased. Different recipients of the same estate can face different tax outcomes.

• Estate tax example: An estate of 20 million dollars is assessed under federal estate tax rules. After deductions and credits, the estate itself pays any federal estate tax due before distributing what remains to the heirs.
• Inheritance tax example: A state might charge 5% on the amount each beneficiary receives above 2 million dollars. If you inherit 5 million dollars, 3 million is taxed at 5%, giving a 150,000-dollar inheritance tax bill for you personally.

Capital gains and income taxes add another layer of complexity in some countries. Canada, for instance, does not have a traditional inheritance tax. Instead, when a person dies, they are generally treated as having disposed of their assets at fair market value, and any unrealized gains are taxed as capital gains on their final return. Similarly, several jurisdictions treat inheritances as exceptional or capital income and subject them to income tax rather than a separate inheritance tax.

To complicate matters further, not every country uses these terms in the same way. In the United Kingdom, for example, “inheritance tax” is actually a tax on the deceased’s estate rather than on individual recipients, so in technical terms it functions like an estate tax. For international tax planning, you always need to check the local definition, not just the label.

How inheritance tax works in U.S. states

In the U.S., inheritance tax is purely a state-level issue, and only a small minority of states still levy it. The tax generally applies based on the deceased person’s state of domicile or the location of property, not where the beneficiary lives. Personal representatives are typically responsible for filing state inheritance tax returns, but the actual tax can be owed either by the estate or by the individual heirs, depending on the state rules.

Non‑resident decedents can also trigger inheritance tax if they owned real estate or tangible personal property in an inheritance‑tax state. For example, real property located in a state that levies inheritance tax may be taxable even if the decedent lived elsewhere.

Most states that impose inheritance tax give very favorable treatment to spouses and close relatives. Spouses are almost always fully exempt, and lineal heirs (children, grandchildren, parents) are often either exempt or taxed at lower rates and higher thresholds than more distant relatives or unrelated beneficiaries.

States that impose inheritance tax

As of 2025, five states impose an inheritance tax: Kentucky, Maryland, Nebraska, New Jersey and Pennsylvania. Iowa fully phased out and then repealed its inheritance tax for deaths occurring on or after January 1, 2025. Tax rates and exemptions differ markedly from state to state.

• Kentucky: Spouses, parents, children and siblings are exempt. Other family members (excluding cousins) typically get a 1,000-dollar exemption and then face rates from 4% to 16%. Cousins and unrelated beneficiaries usually have only a 500-dollar exemption and pay 6% to 16%, with minimum tax amounts and brackets at various thresholds.
• Maryland: Parents, grandparents, spouses, children, grandchildren, siblings and qualifying charities are exempt. Small estates under set values can also be exempt (for example, certain estates at or under 50,000 or 100,000 dollars depending on who inherits). Non‑exempt beneficiaries face a flat 10% rate on taxable inheritances.
• Nebraska: Spouses, relatives under age 22 and charities are fully exempt. Immediate family members such as parents, grandparents, siblings, children and grandchildren receive a 100,000-dollar exemption and then pay 1% above that. Other relatives generally receive a 40,000-dollar exemption with an 11% rate on the excess. Beneficiaries with no family relationship receive about 25,000 dollars exempt and then pay 15% above that amount.
• New Jersey: Spouses, children, grandchildren, parents, grandparents and qualifying charities are exempt. Siblings as well as sons‑ and daughters‑in‑law receive a 25,000-dollar exemption; amounts above that are taxed at progressive rates from 11% up to 16%. More remote relatives and non‑relatives typically pay 15% or 16%, depending on the size of the inheritance.
• Pennsylvania: Transfers to surviving spouses and from a parent to a child age 21 or younger are exempt. A one‑time family exemption of 3,500 dollars may apply to certain probate assets for adult children, parents and grandparents. Tax rates are tiered by relationship: 4.5% for lineal heirs, 12% for siblings and 15% for other beneficiaries, with some asset‑specific exemptions such as life insurance proceeds.

In all of these states, the tax is generally calculated on the fair market value of the property at the decedent’s date of death, reduced by any applicable exemptions. Returns and payments are normally due within a set period (often several months) after death, although interest and penalties can apply for late filing or payment.

How inheritance tax is calculated and who files

Calculating inheritance tax in a state that imposes it usually involves three basic steps: valuing what you receive, applying the right exemption for your relationship group and then using the relevant rate schedule. Only the amount above the exemption is subject to tax, and many states apply a sliding scale so that higher inheritances are taxed at higher marginal rates.

Many states classify beneficiaries into groups or classes based on how closely they are related to the decedent. For example, Class A might include spouses and lineal heirs and be exempt; Class C might capture siblings with modest exemptions and moderate rates; Class D could include everyone else with no exemption and the highest rates. The same estate can therefore produce very different bills for different recipients.

The executor or personal representative usually prepares and files the inheritance tax return, but the legal liability for the tax often remains with each beneficiary. Some states allow or require the estate to pay the tax on behalf of heirs; others expect beneficiaries to pay their own liability directly. The return will list the beneficiaries, what each received and the amounts of tax due.

Only a small share of Americans will ever pay inheritance tax. Because only five states impose it and those states offer generous exemptions for close relatives and smaller inheritances, estimates suggest that roughly 2% of people will face an inheritance tax in practice. Nonetheless, the potential for tax can be a strong motivator for estate planning in these jurisdictions, especially for larger estates and for bequests to friends or more distant relatives.

Federal estate tax in the United States

While there is no federal inheritance tax, there is a federal estate tax that applies to large estates; this is often what people mean when they talk about “death tax” in the U.S. The Internal Revenue Service (IRS) imposes this tax on the right to transfer property at death, based on the total value of what a person owns or has certain interests in when they die.

The federal estate tax calculation begins with the “gross estate”, which includes essentially all property interests the decedent held at death. This can cover cash, bank accounts, publicly traded securities, real estate, business interests, some life‑insurance‑related interests, trusts, annuities and other assets valued at fair market value on the date of death (or, if elected, an alternate valuation date in certain cases).

From the gross estate, the law allows a range of deductions to arrive at the “taxable estate”. Common deductions include mortgages and other debts, funeral and administration expenses, certain losses, property passing to a surviving spouse (the marital deduction) and property passing to qualifying charitable organizations. Some farming and business interests can be valued at a reduced amount if they meet strict criteria.

Once the taxable estate is determined, any lifetime taxable gifts made since 1977 are added back to compute the “tax base” on which the estate tax is applied. The resulting tax is then reduced by a unified credit, which effectively shelters a very large amount of wealth from federal estate tax.

Thanks to legislative changes, the federal exemption is extremely high for most families. Under the Tax Cuts and Jobs Act (TCJA) of 2017, the exemption roughly doubled from 5.49 million dollars to 11.18 million dollars per person, indexed for inflation. For 2024 it stands at 13.61 million dollars for an individual (27.22 million dollars for a married couple). Later legislation increased the threshold further to 15 million dollars starting in 2026, again indexed for inflation, rather than letting it fall back by half when the TCJA provisions would otherwise have expired.

In practice, this means that only very large estates owe federal estate tax; most relatively simple estates with mainstream assets never need to file Form 706 at all. A federal estate tax return is required only if the gross estate, plus adjusted taxable gifts and any specific gift tax exemptions, exceeds the applicable filing threshold for the year of death or if the estate wants to elect “portability” of unused exemption to a surviving spouse.

Portability of the federal exemption between spouses

Beginning in 2011, estates of decedents survived by a spouse have been able to elect to transfer any unused portion of the federal estate tax exemption to the surviving spouse. This is known as “portability” and is claimed by filing a timely estate tax return for the first spouse to die, even if no tax is actually due.

Portability allows married couples to use both spouses’ exemptions more flexibly, simplifying planning for many families. Instead of relying entirely on complex trust structures, a surviving spouse can directly benefit from any unused exemption of the deceased spouse, subject to specific IRS rules and filing requirements.

State estate taxes and how they interact with inheritance tax

On top of—or instead of—inheritance tax, some U.S. states impose their own estate taxes, which apply to the total estate in a way similar to the federal tax. State exemptions are generally much lower than the federal threshold and can therefore affect a broader range of estates.

As of the mid‑2020s, a dozen states plus the District of Columbia levy an estate tax, including Connecticut, Hawaii, Illinois, Maine, Massachusetts, Maryland, New York, Oregon, Minnesota, Rhode Island, Vermont, Washington and D.C. Exemptions and rate structures vary widely. Connecticut is currently the only state that fully aligns its exemption with the federal level, while states like Oregon and Rhode Island have exemptions as low as 1 million dollars and around 1.8 million dollars respectively.

Maryland is unique in the U.S. because it levies both an estate tax and an inheritance tax. This can, in unusual circumstances, result in assets being exposed to both levies, although careful planning and exemptions for spouses and certain transfers can mitigate double taxation in most common family situations.

States frequently adjust their estate tax rules in response to federal law changes and economic or political pressure. After the federal government phased out the credit for state estate taxes in 2005, many states that had “pick‑up” taxes automatically stopped collecting, while others proactively repealed or scaled back their estate taxes to remain competitive and avoid encouraging wealthy residents to relocate.

Recent years have seen a continuing trend of states moving away from estate and inheritance taxes or raising exemptions, but there are exceptions. For example, Washington state increased its estate tax rates in 2025 (raising most brackets and the top rate from 20% to 35%), while at the same time lifting its exemption from roughly 2.19 million dollars to 3 million dollars. Maine and New York have indexed exemptions that step up periodically with inflation.

How inheritance tax is treated internationally

Outside the U.S., inheritance and estate taxation varies enormously, from countries with very high rates to jurisdictions with no tax at all on death. Some impose classic inheritance taxes on the recipient, others levy estate‑style taxes on the deceased’s assets, and some instead tax inheritances as capital gains or ordinary income.

Historically, many countries introduced or strengthened inheritance taxes during the 19th and early 20th centuries, only to roll them back in the second half of the 20th century. Since around 1960 there has been a notable global trend toward repealing or softening inheritance taxes, often motivated by concerns about capital flight, economic efficiency and fairness perceptions.

Examples of countries with inheritance or estate‑type taxes include Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Japan, South Korea, Luxembourg, the Netherlands, Poland, Slovenia, Spain, Turkey and others. In many of these, rates and exemptions depend strongly on the relationship between the decedent and beneficiary: close family members enjoy higher allowances and lower rates, whereas distant relatives and unrelated heirs can face steep marginal rates, sometimes above 40% or even 50% on large bequests.

Conversely, several countries have abolished their inheritance or estate taxes outright, often replacing them with capital gains or income tax treatment of inheritances. Australia, Austria, Canada, the Czech Republic, Estonia, Hong Kong, India, Israel, Kenya, Malaysia, New Zealand, Norway, Singapore, Sweden, Portugal, Slovakia and others have removed formal inheritance taxes, though many still tax certain gains when inherited assets are later sold or deemed disposed of.

Some jurisdictions—such as the Cayman Islands, Guernsey, Jersey and Jordan—have never imposed any kind of inheritance or estate tax. These locations are sometimes seen as particularly attractive for international estate planning, though broader tax and regulatory changes impacting money transfers also play a major role in where people choose to live or hold assets.

A number of legal systems blend inheritance tax and gift tax concepts by taxing certain lifetime transfers in a similar way to inheritances. For example, the United Kingdom’s inheritance tax regime also applies to some “chargeable lifetime transfers”, such as gifts into certain types of trusts, while treating normal gifts differently depending on whether the donor survives for a number of years after making them.

Cash inheritances and income tax

One of the biggest questions people have when they receive money from a will is whether that cash counts as taxable income. Under U.S. federal income tax rules, cash you inherit is not treated as taxable income simply because you received it from an estate.

However, earnings generated by inherited money or property after you receive it are usually taxable under normal rules. For example, if you place inherited cash into an interest‑bearing savings account, the interest you earn each year is subject to income tax. Similarly, dividends from inherited stocks, rental income from inherited real estate and realized capital gains when you sell inherited investments are generally taxable unless a specific exclusion applies.

Other countries can take very different approaches. Some, as noted above, treat inheritances as extraordinary or capital income and tax them through the income tax system at specific rates. Others apply a combination of capital gains rules at death and inheritance tax or estate tax, while providing exemptions to avoid double taxation of the same gain.

Planning strategies to reduce or avoid inheritance tax

Because inheritance and estate taxes are triggered at a very sensitive moment and often involve illiquid assets like family businesses or farms, much of the policy debate focuses on how to reduce their economic and emotional burden. On a personal level, proactive planning can significantly reduce exposure, especially in states and countries that still rely heavily on these taxes.

One straightforward strategy is to structure bequests in favor of beneficiaries who qualify for full exemptions or lower rates. In many inheritance‑tax states and countries, spouses and lineal descendants face little or no inheritance tax. Leaving certain assets to those beneficiaries instead of to more distant relatives or friends can lower the overall tax burden, although personal and family priorities naturally come first.

Lifetime gifts can also play a major role, especially in systems that coordinate gift and inheritance taxes. In the U.S., for example, there is an annual gift tax exclusion (18,000 dollars per recipient in 2024) that allows you to transfer that amount each year to as many people as you like without tapping into your lifetime gift and estate tax exemption. Amounts above the annual exclusion count against your lifetime exemption, which is aligned with the federal estate tax threshold.

Trusts are another widely used tool, particularly irrevocable trusts that remove assets from your taxable estate for estate or inheritance tax purposes. By placing property into an irrevocable trust during your lifetime, you may be able to keep future growth outside your estate while still controlling how and when beneficiaries receive the assets. Trusts can also help address non‑tax goals such as protecting beneficiaries from creditors or managing assets for minors or individuals with special needs.

In some states, simply changing residence can eliminate exposure to inheritance tax—but this approach is far from trivial. Moving to a state without inheritance tax before death can mean that certain assets are no longer subject to that state’s levy, but there are many legal, financial and personal factors to weigh, from domicile rules to quality of life, healthcare access and other state taxes.

Life insurance is frequently used to provide liquidity for heirs who may otherwise struggle to pay estate or inheritance taxes on illiquid assets. While life‑insurance proceeds have their own tax rules, they are often received income‑tax‑free and, with appropriate structuring, can sit outside the taxable estate, providing funds to cover tax bills without forcing the sale of key family assets at a bad time.

Given the complexity and the significant sums often involved, professional tax and estate‑planning advice is strongly recommended for anyone with substantial assets or ties to multiple jurisdictions. Rules can change frequently—as seen with the phase‑out of Iowa’s inheritance tax, recent adjustments to Washington state’s estate tax and various international reforms—so strategies must be reviewed periodically to stay effective.

Inheritance tax and related levies on wealth transfers sit at the intersection of tax policy, family planning and economic debate: only a small fraction of people currently pay them, but for those who do, a blend of thoughtful planning, awareness of state and international differences and timely professional support can make the difference between a smooth transfer of assets and a costly, stressful experience.
