What Is Inheritance Tax?

An inheritance tax is a tax imposed by some states on the recipients of inherited assets. In contrast to an estate tax, an inheritance tax is paid by the recipient of a bequest rather than the estate of the deceased.

The inheritance tax is not common in the U.S. In fact, just six states have an inheritance tax as of 2023, and the taxation depends on the state in which the deceased lived or owned property, the value of the inheritance, and the beneficiary's relationship to the decedent.

Understanding Inheritance Taxes

An inheritance tax is not the same as an estate tax. An estate tax is assessed on the estate itself before its assets are distributed, while an inheritance tax may be imposed on the bequest's beneficiaries. 

There is no federal inheritance tax in the U.S. While the U.S. government taxes large estates directly—imposing estate taxes and, if relevant, income tax on any earnings from the estate—it does not impose an inheritance tax on those who receive assets from an estate.

Inheritance taxes are collected by six U.S. states: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Whether your inheritance will be taxed, and at what rate, depends on its value, your relationship to the person who passed away, and the prevailing rules where you live.

Inheritance tax may be assessed by the state or states where the decedent lived or owned property.

How Inheritance Taxes Are Calculated

An inheritance tax, if due, is applied only to the portion of an inheritance that exceeds an exemption amount. Above those thresholds, tax is usually assessed on a sliding basis. Rates typically begin in the single digits and rise to between 15% and 18%. Both the exemption you receive and the rate you're charged may vary with your relationship to the deceased—more so than with the value of assets you are inheriting.

As a rule, the closer your familial relationship to the deceased, the higher the exemption and the lower the rate you'll pay. Surviving spouses are exempt from inheritance tax in all six states. Domestic partners, too, are exempt in New Jersey. Descendants are only subject to an inheritance tax in Nebraska and Pennsylvania.

Inheritance Tax Thresholds

In most states, an inheritance tax applies to bequests above a certain amount. In a few instances, the size of the estate is significant. For example:

• In Iowa, if the estate is valued at less than $25,000 then no tax is due when property passes to the recipients.
• In Maryland, inheritances from estates smaller than $50,000 are also exempt.

There are further exemptions for heirs, depending on how closely related they were to the deceased. Here are the details by state:

• Iowa: Spouses, lineal ascendants (parents, grandparents, and great-grandparents), and lineal descendants (children, stepchildren, grandchildren, and great-grandchildren) are exempt; charities exempt up to $500. The tax rate on others ranges from 2% to 6% of inheritance. Iowa's inheritance tax will be repealed in 2025.
• Kentucky: Immediate family members (spouses, parents, children, siblings) are exempt; other recipients exempt up to $500 or $1,000. The tax is on a sliding scale based on the size of inheritance and includes a minimum amount, plus a percentage ranging from 4% to 16%.
• Maryland: Immediate family (parents, grandparents, spouses, children, grandchildren, siblings) and charities exempt; other recipients exempt up to $1,000. The tax rate is 10%.
• Nebraska: Spouses and charities fully exempt; immediate family (parents, grandparents, siblings, children, grandchildren) exempt up to $100,000, starting in 2023. Other relatives are exempt up to $40,000 and unrelated heirs up to $25,000. Nebraska lowered its tax rates to 1%, 11%, and 15% in 2023.
• New Jersey: Immediate family (spouse, children, parents, grandparents, grandchildren) and charitable organizations exempt. Siblings and sons/daughters-in-law exempt up to $25,000. The tax rate ranges from 11% to 16%, depending on the size of inheritance and the familial relationship.
• Pennsylvania: Spouse and minor children exempt. Adult children, grandparents, and parents are exempt up to $3,500. The tax rate is 4.5%, 12%, or 15%, depending on the relationship.

Inheritance Tax vs. Estate Tax

Inheritance taxes and estate taxes are often lumped together. However, they are two distinct forms of taxation.

Both levies are based on the fair market value of a deceased person's property, usually as of the date of death. But an estate tax is levied on the value of the decedent's estate, and the estate pays it. In contrast, an inheritance tax is levied on the value of an inheritance received by the beneficiary, and it is the beneficiary who pays it.

The distinction between an estate tax and an inheritance tax with identical rates and exemptions might make no difference to a sole heir. But in some rare situations, an inheritance could be subject to both estate and inheritance taxes.

According to the Internal Revenue Service (IRS), federal estate tax returns are only required for estates with values exceeding $12.92 million in 2023 ($13.61 in 2024). If the estate passes to the spouse of the deceased person, no estate tax is assessed.

If a person inherits an estate large enough to trigger the federal estate tax, the decedent lived or owned property in a state with an inheritance tax, and the bequest is not fully exempt under that state's law, the beneficiary faces the federal estate tax as well as a state inheritance tax. The estate is taxed before it is distributed, and the inheritance is then taxed at the state level. 

Heirs may also face a state estate tax. As of 2023, 12 states and one district still collected estate taxes: Connecticut, District of Columbia, Hawaii, Illinois, Maine, Massachusetts, Maryland, New York, Oregon, Minnesota, Rhode Island, Vermont, and Washington.

If you live in a state with an estate tax, you're more likely to feel its pinch than you are to pay federal estate tax. The exemptions for state and district estate taxes are all less than half those of the federal assessment. Some state estate tax exemptions may be as low as $1 million.

Avoiding Inheritance Tax

While there are a lot of exceptions and exemptions for inheritance taxes, especially for spouses and children, residents with significant assets in a state with one may still want to minimize the exposure for heirs.

One common strategy is to buy a life insurance policy in the sum you wish to bequeath and make the person you want to leave it to the beneficiary of the policy. The death benefit from an insurance policy is not subject to inheritance taxes.

You could also put assets in a trust—preferably an irrevocable trust. This effectively removes them from your estate and their classification as an inheritance upon your death. You can set up a schedule for the distribution of the funds when you establish the trust.

The Bottom Line

Inheritance taxes only affect residents in six states. And they mainly apply to distant relatives or those completely unrelated to the deceased. Spouses are always exempt from paying inheritance tax, and immediate family members like children, parents are often exempt are as well. Still, inheritance taxes can kick in at relatively small inheritance amounts—sometimes as little as $500. Those considering bequests that could be subject to an inheritance tax might consider estate-planning strategies including gifts, insurance policies and irrevocable trusts.
