What Inheritance Taxes Actually Are and Why They Matter

Inheritance taxes are not the same thing as income taxes or property taxes. When someone passes away and leaves money or property to their heirs, some states impose a tax on what those heirs receive. This is fundamentally different from estate taxes, which are taxes on the total value of everything a person leaves behind. Understanding the distinction matters because it shapes how much of an inheritance actually reaches the people named to receive it.

As of 2024, only six states still collect inheritance taxes: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Each state has different rules about who pays the tax, what counts as taxable property, and what exemptions apply. For example, Nebraska taxes direct descendants (like children) at lower rates than distant relatives or unrelated beneficiaries. Iowa taxes spouses differently than siblings. These variations mean that the same inheritance could result in drastically different tax bills depending on which state the deceased person lived in or owned property in.

Federal estate taxes operate under a completely separate system. The federal government taxes estates worth more than a certain threshold—currently $13.61 million per person as of 2024. This number changes yearly and is scheduled to decrease significantly in 2026 unless Congress acts. Most Americans never deal with federal estate taxes because their total assets fall below this threshold. However, families with significant property, business interests, or investment portfolios may need to plan around these potential federal obligations.

The reason this matters extends beyond just the numbers. Understanding whether you're dealing with state inheritance taxes, federal estate taxes, or both shapes every decision in estate planning. A person living in New Jersey faces entirely different tax considerations than someone in Colorado, where there is no inheritance or estate tax. These taxes can significantly reduce what heirs receive, which is why families often engage in planning years before anyone passes away.

Practical takeaway: Before diving into estate planning, identify which state's inheritance tax rules apply to your situation. This determines what planning strategies may be worth exploring and which ones won't make a difference in your specific circumstances.

How State Inheritance Taxes Work in the Six States That Have Them

Pennsylvania's inheritance tax illustrates how these taxes function in practice. When a Pennsylvania resident dies, heirs are required to report their inheritance to the state within eight months. The tax rate depends entirely on the relationship between the deceased and the heir. Spouses and direct descendants in the first degree pay 0%. Children pay 4.5%. Grandchildren pay 9%. More distant relatives or unrelated individuals pay 15%. The same $100,000 inheritance could result in $0 in taxes if you're a surviving spouse, but $15,000 if you're a friend or distant cousin of the deceased.

New Jersey uses a similar relationship-based system but with different thresholds. Certain close relatives—spouses, children under 25, parents, and grandparents—are completely exempt from New Jersey's inheritance tax regardless of the amount inherited. For other heirs, the tax rates range from 11% to 16%, but only on amounts above certain exemption thresholds. A child in New Jersey pays no inheritance tax, while a nephew or niece pays tax on inherited amounts above $25,000.

Kentucky's inheritance tax applies primarily to heirs who are not direct descendants. Spouses and direct descendants are exempt from Kentucky's tax entirely. All other beneficiaries pay a sliding scale based on how much they inherit, with rates ranging from 4% to 16%. Iowa similarly exempts spouses and minor children from its inheritance tax, while taxing other beneficiaries at rates between 1% and 15%.

Maryland and Nebraska round out the six inheritance-tax states with their own variations. Maryland taxes all heirs except spouses at rates between 1% and 10%. Nebraska has one of the more complex systems, with different rates for different classes of beneficiaries and numerous exemptions for agricultural property, life insurance proceeds, and other assets.

What connects all six states is that the tax obligation belongs to the heir, not the estate. The estate doesn't pay the inheritance tax—the person who receives the inheritance does. This creates important planning considerations. In some cases, people structure their wills or use other legal arrangements to shift assets in ways that might reduce inheritance taxes for certain beneficiaries.

Practical takeaway: If you live in one of these six states, determine where you rank in the relationship classifications used by your state's tax code. This shows you roughly how much tax you might owe (if any) on various amounts of inheritance.

Federal Estate Taxes and the High-Value Estate Threshold

Federal estate taxes operate on a completely different playing field from state inheritance taxes. The federal system doesn't care whether you're leaving money to a spouse, a child, or a charity—the tax is based solely on the total value of your estate, not the relationships involved. This is a crucial distinction that confuses many people who think federal and state systems work the same way.

The federal estate tax exemption for 2024 sits at $13.61 million per individual, or $27.22 million for a married couple. Any estate valued below these thresholds owes zero federal estate tax, regardless of size. An estate worth $5 million, $8 million, or $13.6 million pays nothing to the federal government. Only the value above the exemption threshold is taxed, and the tax rate is 40%. This means a $14.61 million estate would owe taxes on just $1 million at 40%, resulting in a $400,000 federal tax bill.

The complication everyone should watch is that this exemption is temporary. The current exemption was established by the 2017 Tax Cuts and Jobs Act and is scheduled to sunset on December 31, 2025. When that happens, the exemption is scheduled to drop to approximately $7 million per person (adjusted for inflation), effective in 2026. This means families with estates between $7 million and $13.61 million are in a unique planning window right now. Strategies that make sense in 2024 might look different after 2025.

It's important to understand that federal estate taxes apply to all assets, not just cash. If you own a house worth $2 million, business interests worth $3 million, investment accounts worth $4 million, and life insurance policies worth $5 million, that $14 million total is what counts toward the threshold. Many people underestimate their estate value because they don't think about life insurance proceeds or the appreciated value of long-held property.

States with their own estate taxes layer on top of federal taxes. Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Minnesota, New York, Oregon, Rhode Island, Vermont, and Washington all have state estate taxes. A resident of Massachusetts with a $15 million estate might owe both Massachusetts state estate tax and federal estate tax on portions of that wealth.

Practical takeaway: Calculate your total estate value including property, financial accounts, retirement accounts, life insurance death benefits, and business interests. If that number approaches $7 million or higher, the federal exemption changes coming after 2025 should factor into your planning decisions.

How Wills, Trusts, and Property Titles Affect Tax Outcomes

The way you structure ownership of your assets has enormous consequences for how taxes apply after your death. This is where estate planning connects directly to tax planning—the two cannot be separated. The same $2 million house can result in completely different tax outcomes depending on whether it's in your individual name, in a trust, held as joint property with your spouse, or owned through a business entity.

Property owned as "joint tenants with rights of survivorship" passes directly to the surviving joint owner outside of probate. For federal estate tax purposes, the full value of jointly owned property is included in the estate of the first person to die, with one significant exception: property held jointly by spouses is treated differently, with each spouse's share included in their own estate. This distinction matters enormously for couples in high-net-worth situations. A married couple with a $5 million house held jointly can structure their ownership to ensure the house doesn't push either individual estate above exemption thresholds.

Revocable living trusts are frequently used in estate planning, though not primarily for tax reasons. These trusts hold the legal title to assets and pass them to beneficiaries without going through probate. However, for federal estate tax purposes, assets in a revocable trust are fully included in your taxable estate because you retain control over the trust during your lifetime. The tax
