New Jersey Estate Tax Calculator
Estimate the federal estate tax AND the New Jersey inheritance tax on a New Jersey decedent’s estate. New Jersey repealed its estate tax for deaths on or after January 1, 2018, but keeps a beneficiary-level inheritance tax: Class A heirs (spouse, partners, parents, children, grandchildren) and charities pay nothing, siblings and in-laws pay 11% to 16% above a $25,000 exemption, and everyone else pays 15% to 16%. Three modes: estimate the tax, test a larger estate, or solve for the years of gifting needed to reach zero. Fields marked * are required; Calculate names any left empty.
Federal: unified estate and gift schedule topping at 40%; basic exclusion $13,610,000 (2024), $13,990,000 (2025), $15,000,000 (2026); federal portability (DSUE) allowed; unlimited marital and charitable deductions; GST 40%.

How it works
- New Jersey taxes beneficiaries, not the estate. The New Jersey estate tax was repealed for deaths on or after January 1, 2018; the surviving transfer tax is the inheritance tax (Form IT-R, due 8 months after death): Class A and Class E exempt, Class C 11% to 16% above $25,000, Class D 15% to 16% with no exemption (schedules VERIFY).
- Federal estate tax also applies above the basic exclusion using the unified 18% to 40% schedule; the federal GST applies at 40% to direct skips above the allocated GST exemption (grandchildren remain Class A exempt for New Jersey).
- No community property. New Jersey is a common-law state, so no halving of community assets and no double basis step-up.
- Portability is federal only. A surviving spouse may inherit the unused federal exclusion (DSUE) with a timely Form 706; New Jersey has no state exclusion to port (its estate tax is repealed).
- Elective share. A surviving spouse may elect one-third of the augmented estate under NJSA 3B:8-1 (VERIFY); modeled here on the net estate.
- Small estates. Small-estate administration / affidavit under NJSA 3B:10-4 is available where personal property is $50,000 or less with a surviving spouse, or $20,000 or less without; verify the current figures.
- Binding factor names what controls the result: the federal basic exclusion, the federal unified schedule, the New Jersey inheritance tax, or the GST.
- Gifting mode uses the guarded bisection solver (60 expansions, 90 iterations, rounded up). The entered Class C/D inheritance-tax shares are not reduced by the gifting plan; only the federal base is.
- Gifting is not free. Carryover basis loses the step-up; the deferred gain is netted against the tax saved.

What Is a New Jersey Estate Tax Calculator?
This calculator models transfer taxes for deaths in 2024, 2025, or 2026. In its calculations, New Jersey estate tax is always $0 because the tool treats the state estate tax as repealed for deaths on or after January 1, 2018. It separately calculates New Jersey inheritance tax for entered Class C and Class D beneficiary amounts.
The calculator determines the modeled federal estate tax, New Jersey inheritance tax, GST tax, and total transfer tax from the estate values you provide. It adds estate assets, subtracts modeled deductions and qualifying bequests, applies the selected year’s federal exclusion and any DSUE, and separately taxes entered Class C and Class D transfers.
You can use three calculation modes: estimate tax on the current estate, test whether the estate profile produces transfer tax and show federal headroom, or solve for the number of years of annual-exclusion gifting needed to eliminate the modeled tax within a chosen time limit.
This is an estimate, not legal, tax, or financial advice. The calculator itself flags its New Jersey inheritance schedules, elective-share treatment, and small-estate figures for verification.
How the New Jersey Estate Tax Calculator Works
The calculation starts by adding five asset categories: real property, financial accounts and cash, retirement accounts and annuities, life insurance owned by the decedent, and business interests or other property.
The attorney and executor fee is modeled as the entered percentage of the gross estate after debts, but not below zero. Court costs are then added to that administration amount.
Total modeled deductions include debts, funeral expenses, administration costs, and entered casualty or theft losses. The calculator calls the remaining amount the net estate.
A spousal bequest reduces the federal taxable estate when the decedent is marked married and the surviving spouse is a U.S. citizen or the non-citizen spouse’s bequest passes to a QDOT. The deduction cannot exceed the modeled net estate. The charitable deduction is then limited to the amount remaining after the marital deduction.
Earlier taxable gifts are added to the taxable estate to form the federal tax base. The applicable federal exclusion equals the basic exclusion for the selected year plus entered DSUE. The calculator uses basic exclusions of $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026.
If the federal base exceeds that exclusion, the calculator applies its progressive 18% through 40% federal schedule to both amounts. Federal estate tax is the schedule tax on the federal base minus the schedule tax on the applicable exclusion. Otherwise, federal estate tax is $0.
New Jersey inheritance tax is calculated separately. For Class C, the calculator first subtracts a $25,000 exemption, floors the result at zero, and applies its graduated 11% through 16% schedule. Class D has no modeled exemption and uses 15% on the first $700,000 and 16% above $700,000. The calculator treats Class A and Class E transfers as exempt.
GST tax equals 40% of direct skips remaining after the entered GST exemption. Finally, total transfer tax adds federal estate tax, New Jersey inheritance tax, New Jersey estate tax of $0, and GST tax.
Worked Example
Consider the calculator’s 2025 example with a $20,000,000 gross estate, $500,000 of debts, $20,000 of funeral expenses, a 2% attorney and executor fee, $400 of court costs, and a $1,000,000 Class D transfer. There are no marital or charitable deductions in this example.
The administration cost is $390,400. Total deductions are $910,400, leaving a modeled net and taxable estate of $19,089,600. Against the calculator’s $13,990,000 federal exclusion for 2025, its progressive federal schedule produces $2,039,840 of federal estate tax.
The $1,000,000 Class D amount produces $153,000 of New Jersey inheritance tax: 15% of the first $700,000 is $105,000, and 16% of the remaining $300,000 is $48,000. With no GST tax, the calculator’s total is $2,192,840.

- Enter earlier taxable gifts, DSUE, direct skips, and the GST exemption allocated.
- For gifting calculations, enter the number of donees, annual gift per donee, unrealized gain, heirs’ selected capital-gains rate, NIIT option, and maximum years to test.
- Check the required acknowledgment and select the calculation button to view the results.
Dollar results are displayed as U.S. currency rounded to the nearest whole dollar. Effective rates are shown as percentages. The detailed results break out the federal tax, Class C and Class D inheritance taxes, GST tax, deductions, taxable estate, exclusion information, filing indicators, and other modeled estate figures.
Understanding the Results and Assumptions
The main estate mode reports total transfer tax due. This total can contain federal estate tax, New Jersey inheritance tax, and GST tax. The New Jersey estate-tax component remains $0 under the calculator’s 2024 through 2026 model.
Federal Headroom
The calculator measures federal headroom as the applicable federal exclusion minus the federal tax base, with negative results changed to zero. Its displayed tax-free ceiling adds that headroom to the current gross estate. This is a modeled federal measure for the entered profile. New Jersey inheritance tax can still arise from Class C or Class D amounts.
Annual-Exclusion Gifting Mode
Gifting mode limits the modeled gift per donee to the calculator’s annual exclusion: $18,000 for 2024 or $19,000 for 2025 and 2026. It multiplies that amount by the number of donees and years.
The solver searches for the smallest whole number of years that makes total modeled transfer tax zero within the maximum number of years entered. The maximum-years field accepts values from 1 through 200. Because the gifting reduction does not reduce the Class C or Class D amounts entered, their inheritance tax can prevent the solver from reaching zero.
Other Results
For a married decedent, the calculator displays an elective-share estimate equal to one-third of its modeled net estate. It describes this as a proxy for the augmented estate and flags the treatment for verification. It also tests personal property against a $50,000 small-estate limit with a surviving spouse or $20,000 without one, again with the figures flagged for verification.
The calculator treats personal property for this test as financial accounts plus retirement accounts, life insurance, and business or other property. Real property is not included in that particular personal-property total.
Most monetary input fields allow values from $0 to $100,000,000. The attorney and executor fee accepts 0% through 25%, and the number of donees accepts 0 through 200, although gifting mode requires at least one donee. Required selections include the calculation mode, year, county, long-term capital-gains rate, and acknowledgment.
Estate and inheritance taxation can depend on facts beyond this simplified model. Actual filing requirements, deductions, beneficiary treatment, property interests, gift treatment, and other tax or probate consequences may differ. Verify the calculator’s flagged New Jersey figures and use qualified professional advice for an actual estate.

Frequently Asked Questions
Does this calculator charge a New Jersey estate tax?
No. The calculator sets New Jersey estate tax to $0 for all three supported death years, 2024 through 2026. Its New Jersey tax calculation instead focuses on inheritance tax for entered Class C and Class D beneficiary amounts.
How does the calculator handle New Jersey inheritance tax?
It treats Class A and Class E transfers as exempt. For the aggregate Class C amount, it subtracts $25,000 before applying rates from 11% through 16%. For Class D, it applies 15% through $700,000 and 16% above that amount. The calculator labels these inheritance schedules as figures to verify.
What federal estate tax exclusions does the calculator use?
The code uses $13,610,000 for a 2024 death, $13,990,000 for 2025, and $15,000,000 for 2026. Entered DSUE from a predeceased spouse is added to the selected basic exclusion when the calculator determines the applicable federal exclusion.
How does a spousal bequest affect the calculation?
A spousal bequest can reduce the modeled federal taxable estate if the decedent is marked married and the spouse is a U.S. citizen or a QDOT is selected. The allowed deduction is capped at the net estate. Without those conditions, the calculator does not apply the entered spousal bequest as a marital deduction.
How does the gifting solver work?
The solver reduces the modeled taxable estate by annual-exclusion gifts and searches for the first whole number of years that makes total transfer tax zero. It stops at the maximum years you enter. If the tax cannot reach zero within that period, the result reports that more years would be needed.
Does annual-exclusion gifting reduce the Class C or Class D inheritance tax in this calculator?
No. The gifting reduction lowers the modeled federal taxable estate, but the entered Class C and Class D amounts remain unchanged. As a result, New Jersey inheritance tax on those entered amounts can remain even after the modeled federal estate tax reaches zero.
How is the effective transfer tax rate calculated?
The calculator divides total modeled transfer tax by the gross estate. If the gross estate is zero, it uses a 0% effective rate. The displayed effective percentage therefore reflects the combined modeled transfer taxes relative to gross estate, rather than only the federal estate-tax rate.
