Inheritance Tax Calculator

Estimate state inheritance tax based on relationship to decedent and exemption amount.

About this calculator

Inheritance tax is a state-level tax paid by the person who RECEIVES an inheritance, which is a different thing from estate tax, which is paid by the deceased person's estate before assets are distributed -- only a handful of U.S. states levy an inheritance tax at all, and this calculator models a simplified version of how those states typically structure it. The tax rate depends entirely on the recipient's relationship to the decedent: spouses are exempt outright (0%), children and other direct descendants pay the lowest non-zero rate, siblings pay a higher rate, and unrelated beneficiaries or more distant relatives pay the highest rate -- the specific rates here (0% / 4.5% / 12% / 15%) are modeled on Pennsylvania's inheritance tax schedule specifically -- codified at 72 P.S. Sec. 9116 under the state's Inheritance and Estate Tax Act of 1991 -- not a blend or a universal pattern; other states that levy the tax use materially different rates and exemption rules, so treat this as one real state's structure used for illustration, not a composite.

State Exemption is subtracted from the Inheritance Amount before the tax rate applies, so only the portion above the exemption threshold (the Taxable Amount) is actually taxed; if the exemption exceeds the inheritance amount, no tax is owed at all. The exemption figure itself is a simplified placeholder, not any one state's actual threshold -- Pennsylvania, for instance, has no general dollar exemption for lineal descendants, so adjust State Exemption to match your actual state's rules rather than trusting the default. Effective Rate expresses the tax as a percentage of the FULL inheritance amount (not just the taxable portion), which is always lower than or equal to the Applicable Rate whenever any exemption applies, since the exempted portion pulls the effective rate down. This is a simplified illustration, not a substitute for state-specific tax guidance -- as of 2026, only five U.S. states levy an inheritance tax: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania (Iowa repealed its inheritance tax for deaths on or after January 1, 2025), each with its own actual rate schedule, and Maryland uniquely imposes both an estate tax and an inheritance tax.

Figures current as of 1991. Source: 72 P.S. § 9116, Pennsylvania Inheritance and Estate Tax Act of 1991 — rates of 0% (surviving spouse), 4.5% (direct descendants/lineal heirs), 12% (siblings), and 15% (other heirs).

How to Use This Calculator
  1. Enter Inheritance Amount received.
  2. Select Relationship to Decedent: Spouse, Child, Sibling, or Other — rates vary by relationship.
  3. Set State Exemption for your state's inheritance tax rules.
  4. Review Inheritance Tax and Net Inheritance after tax.
  5. As of 2026, only 5 states have inheritance tax: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania (Iowa repealed its inheritance tax for deaths on or after January 1, 2025).
  6. Spouses are typically exempt; children's rates vary. Maryland has both estate and inheritance tax.

What each input means

Inheritance Amount
Total value of inheritance received.
Relationship to Decedent
Your relationship to the decedent determines the applicable tax rate.
State Exemption
A simplified placeholder exemption -- actual states differ significantly (e.g. Pennsylvania has no general exemption for lineal descendants). Adjust to your actual state's threshold.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Inheritance Amount = 500000, Relationship (1=Spouse, 2=Child, 3=Sibling, 4=Other) = 2, State Exemption = 25000 = 3 input(s) provided
  2. Calculate Inheritance Tax
    Inheritance Tax
    21375 = $21,375
  3. Calculate Net Inheritance
    Net Inheritance
    478625 = $478,625
  4. Calculate Taxable Amount
    Taxable Amount
    475000 = $475,000
  5. Calculate Effective Rate
    Effective Rate
    4.3 = 4.3

Frequently Asked Questions

Why is my Effective Rate lower than the Applicable Rate shown?

Applicable Rate is the tax rate that applies to the TAXABLE portion of the inheritance (the amount above your State Exemption), while Effective Rate divides the actual tax owed by the FULL inheritance amount, exemption included. Since the exempted portion pays no tax at all, spreading the same tax dollar amount over a larger base (the full inheritance) always produces a percentage at or below the Applicable Rate -- the two only match exactly when the exemption is zero.

Does a larger inheritance always mean more inheritance tax owed?

Yes -- Inheritance Tax never decreases as Inheritance Amount increases, holding the State Exemption and relationship fixed. Once the inheritance exceeds the exemption threshold, every additional dollar received adds tax at the Applicable Rate; below the exemption threshold, additional dollars add nothing to the tax owed until the threshold is crossed.

How does relationship to the decedent change the tax owed?

Relationship is the single biggest driver of the tax rate in states that levy one: a surviving spouse typically owes nothing, children and direct descendants owe a modest rate, siblings owe a meaningfully higher rate, and unrelated beneficiaries or distant relatives owe the highest rate of all. The same dollar inheritance can produce wildly different tax bills purely based on who is receiving it.

Why do spouses pay no inheritance tax at all?

Every U.S. state that levies an inheritance tax exempts surviving spouses entirely, reflecting a long-standing policy choice to avoid taxing the transfer of assets within a marriage, especially a marital home or shared savings. This unlimited marital exemption is one of the most consistent features across the small number of states that still have an inheritance tax, even though those states otherwise differ significantly in their rates for children, siblings, and other beneficiaries.
