What Is Inheritance Tax and How Does It Differ by State?

Inheritance tax is a state-level tax that some states impose on money or property that passes from a deceased person to their heirs. It's important to understand that inheritance tax is different from federal estate tax. The federal government has an estate tax that applies to very large estates, but inheritance tax is purely a state matter. Only six states currently impose an inheritance tax: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Each of these states has its own rules about who pays the tax, how much they pay, and which assets are taxed.

The key difference between inheritance tax and estate tax relates to who bears the financial responsibility. With inheritance tax, the person receiving the inheritance (the heir or beneficiary) typically pays the tax. With estate tax, the tax is paid from the estate itself before money is distributed to heirs. This distinction matters because it affects how much each beneficiary actually receives.

For example, in Pennsylvania, a child inheriting $100,000 from a parent would pay no inheritance tax because direct descendants are often exempt. However, if a niece inherited the same amount, she might owe 15% in inheritance tax, reducing her inheritance to $85,000. In Iowa, the tax rates depend on the relationship between the deceased person and the beneficiary. The closer the relationship, the lower the tax rate or the larger the exemption.

Many people confuse inheritance tax with estate tax, but they operate very differently. Understanding which applies in your state requires looking at your specific state's laws. No federal inheritance tax exists, so the only inheritance tax people encounter comes from their state of residence or the state where the deceased person lived.

Practical Takeaway: Before assuming you'll owe inheritance tax, identify which state's laws apply to your situation. Check whether your state is one of the six that impose inheritance tax, and research the specific tax rates and exemptions that apply to your relationship to the deceased.

State-by-State Breakdown: The Six States With Inheritance Tax

Iowa is one of the six states with inheritance tax. Iowa taxes beneficiaries based on their relationship to the deceased person, called the "class of inheritance." The tax rates range from 1% to 15%, depending on the relationship. Spouses, children, and grandchildren are in the most favorable classes and may owe little or no tax. More distant relatives and non-relatives pay higher rates. Iowa exempts the first $40,000 of inheritance for Class 1 beneficiaries (immediate family), but the exemption is much smaller or nonexistent for other classes.

Kentucky imposes an inheritance tax on beneficiaries other than spouses and direct descendants (children and grandchildren). The tax applies only to those in Class A, B, C, and D relationships. Spouses and direct descendants are exempt entirely, which is a significant benefit compared to other inheritance tax states. Kentucky's tax rates range from 4% to 16% depending on the amount inherited and the relationship. The state offers substantial exemptions: $1,000 for grandchildren, $500 for siblings, and smaller amounts for more distant relatives.

Maryland taxes all beneficiaries except spouses and charities. However, the state exempts direct descendants (children and grandchildren) in most cases. Maryland's tax rate is 10% on the amount inherited. The state has a graduated structure, meaning larger inheritances face different tax treatment than smaller ones. Linear descendants—meaning children and grandchildren in direct line—are generally not taxed.

Nebraska allows beneficiaries to deduct portions of their inheritance based on their relationship to the deceased. The tax rates range from 1% to 18%. Spouses, children, and grandchildren receive substantial deductions. For example, a spouse can deduct the entire inheritance, while a child can deduct $40,000. Siblings and more distant relatives receive smaller deductions or none at all.

New Jersey has one of the highest inheritance tax rates among the six states. The tax applies to all beneficiaries except spouses and certain direct descendants under specified conditions. Tax rates range from 11% to 16%. New Jersey does provide exemptions for certain amounts depending on the relationship, but these are generally smaller than in other states. The state taxes the transfer of both real and personal property.

Pennsylvania taxes all beneficiaries based on their relationship to the deceased. The tax rates are: 0% for spouses and direct descendants (children and grandchildren), 12% for siblings, and 15% for all other beneficiaries. Pennsylvania's approach is straightforward—the closer your relationship to the deceased, the lower your tax burden. Pennsylvania does not allow deductions based on the size of the inheritance; the rate depends only on the relationship.

Practical Takeaway: Document your relationship to the deceased person and research your state's specific tax rate and exemptions. The difference between being classified as a child versus a sibling can mean the difference between owing no tax and owing 15% or more.

Understanding Tax Rates, Exemptions, and Deductions

Inheritance tax states use different methods to calculate what beneficiaries owe. Some use graduated tax rates, meaning higher amounts are taxed at progressively higher rates, similar to federal income tax. Others use a flat percentage rate applied to all amounts. Understanding how your state calculates the tax is essential for predicting what you might owe.

Exemptions allow beneficiaries to exclude a certain dollar amount from taxation. For example, if a state provides a $40,000 exemption and you inherit $100,000, only $60,000 is subject to tax. Iowa provides a $40,000 exemption for Class 1 beneficiaries, meaning most direct descendants owe no tax on small to moderate inheritances. In contrast, Nebraska provides a $40,000 exemption for children but only $5,000 for siblings and nothing for more distant relatives. These exemptions significantly reduce or eliminate tax liability for close family members.

Deductions work differently than exemptions. Deductions reduce the amount of inheritance subject to tax, while exemptions exclude a set amount from taxation entirely. Some states use both. Pennsylvania uses relationship-based tax rates rather than exemptions or deductions—it's simply 0% for direct descendants, 12% for siblings, and 15% for others.

Tax brackets in inheritance tax states work similarly to income tax brackets. In Iowa, a spouse inheriting $500,000 pays no tax regardless of amount because spouses are exempt. However, a parent inheriting the same amount might face tax starting at 1% on amounts up to a certain threshold, then higher percentages on larger amounts. The specific brackets vary significantly by state.

It's crucial to understand whether your state taxes the full value of what you inherit or only the amount above certain thresholds. Some states allow deductions for funeral expenses or debts of the estate, which reduces the taxable amount. Others tax inheritances of specific assets differently. Real property (land and buildings) might be taxed differently than personal property (money, stocks, household items).

Practical Takeaway: Calculate your estimated tax liability using your state's specific exemptions, deductions, and tax rates. Many state tax authority websites provide calculators or worksheets to estimate what you might owe. Using these tools before inheritance is distributed helps you plan financially.

Assets That Are Typically Exempt From Inheritance Tax

Most inheritance tax states exempt certain types of assets from taxation entirely. Understanding which assets are exempt can significantly reduce the actual tax burden on your inheritance. Life insurance proceeds are exempt from inheritance tax in all six inheritance tax states. If the deceased person had a $500,000 life insurance policy, that amount typically passes to named beneficiaries without being subject to inheritance tax. This is one reason many people use life insurance as an estate planning tool.

Retirement accounts and IRAs are often treated specially under inheritance tax laws. Many states exempt or provide favorable treatment for inherited retirement accounts, particularly when the inheritance goes to a spouse or direct descendant. The specific rules vary by state, but generally, inherited IRAs and 401(k)s receive some protection from inheritance taxation. However, beneficiaries may still owe income tax when they withdraw money from the account later.

Property transferred through a trust often receives favorable treatment. If the deceased person set up a living trust and transferred property into it before death, those assets might avoid inheritance tax or receive reduced taxation. This is another reason estate planning attorneys often recommend trusts in inheritance tax states.

Jointly owned property with right of survivorship typically passes to the surviving owner outside the prob
