Understanding Estate and Gift Taxes in the United States
Estate and gift taxes are transfer taxes levied on the movement of wealth, either at death (estate tax) or during life (gift tax). The federal government imposes a unified tax with a high lifetime exemption. Many states also levy their own estate or inheritance taxes, with much lower thresholds. This calculator helps estimate potential liabilities from both sources, using current projections for key figures.
How Federal Estate and Gift Tax Works
The federal system provides a lifetime exemption—$13.4 million per person in 2026—that applies to the total of taxable gifts made during life and the value of your estate at death. Gifts to an individual that exceed the annual exclusion ($18,000 in 2026) count against this lifetime limit. Any taxable transfer above the exemption is taxed at a flat rate of 40%.
For estates, the tax is calculated on the total gross value of assets owned at death, minus debts, administrative expenses, and the exemption. For gifts, the tax is calculated on the value given, minus the annual exclusion and any remaining lifetime exemption.
How State Taxes Work
State-level taxes add complexity:
- Estate Tax States: States like New York, Washington, and Illinois impose their own estate tax, often with an exemption far lower than the federal one (e.g., $1 million in Oregon, $6.5 million in New York for 2026). The tax is paid from the estate's assets.
- Inheritance Tax States: States like Pennsylvania, Nebraska, and New Jersey tax the beneficiary's right to receive property. Rates depend heavily on the beneficiary's relationship to the decedent. Spouses are often exempt, lineal descendants (children, grandchildren) pay a low rate, siblings a medium rate, and unrelated heirs the highest rate. This calculator uses a simplified flat rate applied to a single beneficiary's share for estimation only.
- No State Tax: The majority of states impose neither tax.
Example Calculation for a New York Estate
Consider a single individual in New York with a taxable estate valued at $20 million in 2026.
- Federal Tax: Taxable base: $20,000,000 - $13,400,000 = $6,600,000. Federal tax at 40%: $2,640,000.
- New York State Tax: New York's estate tax exemption is approximately $6,544,000. The state taxable base is $20,000,000 - $6,544,000 = $13,456,000. New York's estate tax is progressive, but for this simplified example using a flat 16% rate, the estimated tax is $2,152,960.
- Total Estimated Liability: Combined federal and state tax: approximately $4,792,960.
Example for an Inheritance Tax State
Consider an $800,000 estate in Pennsylvania where a single child inherits 50% ($400,000). Pennsylvania's inheritance tax for lineal descendants is 4.5%. The estimated inheritance tax for that child's share would be $18,000. A sibling inheriting the same share would pay a higher rate (12%), resulting in $48,000—highlighting why beneficiary relationship is critical.
Common Planning Scenarios
Married couples can often defer all estate tax until the second spouse's death using the unlimited marital deduction. For estates near the exemption, strategies like annual gifting, trusts, and charitable donations can help manage exposure. For smaller estates, the primary concern is often state-level tax, as the federal exemption is high.
Next Steps and Documents
For comprehensive estate planning, a Living Trust Agreement helps manage and distribute assets while potentially avoiding probate. It is complemented by a Pour-Over Will to catch any assets not in the trust. To formally document a significant financial gift, a Gift Affidavit provides clear evidence of the transfer's nature for tax and legal purposes.
