New Hampshire Estate Tax Calculator

Estimate the federal estate tax on a New Hampshire decedent’s estate and confirm that New Hampshire itself charges nothing. New Hampshire repealed its estate tax for deaths on or after January 1, 2005, and has no inheritance tax and no gift tax, so for 2024-2026 deaths New Hampshire tax is $0. Distinctive rules modeled: the spousal waiver share ($25,000 plus half the remainder, or the whole estate) and the small-estate affidavit. 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.

New Hampshire rules this calculator enforces: NO state estate tax for deaths on or after January 1, 2005 (RSA 74 repealed; VERIFY exact date), and the pre-repeal tax was largely a pick-up tied to the federal state death tax credit (zero after 2004), so no New Hampshire estate tax return is filed; no inheritance tax; no gift tax; common-law (equitable distribution) state, not community property; spousal waiver / elective share of $25,000 plus one-half of the net estate above $25,000 when the decedent left issue or parents, otherwise the whole net estate (RSA 560:10; VERIFY), capped at the net estate; small-estate affidavit where personal property is $10,000 or less (RSA 553:32; VERIFY current figure); probate venue in the Probate Court of the county of domicile (10 counties).
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 Hampshire charges nothing for recent deaths. The New Hampshire estate tax (RSA 74) was repealed for deaths on or after January 1, 2005 (VERIFY exact date), and before repeal was largely a pick-up tied to the federal state death tax credit, so no New Hampshire estate tax return is filed. There is no New Hampshire inheritance tax and no New Hampshire gift tax.
  • Only federal transfer taxes apply. The federal estate tax applies above the basic exclusion using the unified 18% to 40% schedule, and the federal GST applies at 40% to direct skips above the allocated GST exemption.
  • No community property. New Hampshire 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 election; there is no New Hampshire state exclusion to port.
  • Waiver share. A surviving spouse may waive the will and take $25,000 plus one-half of the net estate above $25,000 if the decedent left issue or parents, otherwise the whole net estate (RSA 560:10; VERIFY); the figure is capped at the net estate.
  • Small estates. The affidavit for collection of personal property under RSA 553:32 is available where personal property is $10,000 or less; verify the current figure.
  • Binding factor names what controls the result: the federal basic exclusion, the federal unified schedule above it, or the GST.
  • Gifting mode uses the guarded bisection solver (60 expansions, 90 iterations, rounded up) to find the years of annual-exclusion gifting that bring the taxable estate to the exclusion or below.
  • Gifting is not free. Carryover basis loses the step-up; the deferred gain is netted against the tax saved.

What Is a New Hampshire Estate Tax Calculator?

The New Hampshire estate tax calculator estimates federal estate tax, GST tax, and total transfer tax using the assets, deductions, bequests, prior gifts, portability, and generation-skipping amounts you enter. It treats New Hampshire estate, inheritance, and gift taxes as $0 while separately showing state-related probate and spousal-share estimates.

The calculator supports deaths in 2024, 2025, and 2026. It builds a gross estate from several asset categories, subtracts modeled expenses and qualifying bequests, adds earlier taxable gifts to the federal base, and compares that amount with the applicable federal exclusion.

Three modes are available. Estate mode estimates transfer tax on the entered estate. Headroom mode shows whether the profile produces tax and how much federal exclusion remains. Gifting mode searches for the number of years of annual-exclusion gifts needed to bring modeled total transfer tax to $0 within the selected time horizon.

The calculator flags the New Hampshire estate-tax repeal date, spousal waiver-share rule, and $10,000 small-estate threshold for verification. Its results are estimates rather than legal, tax, or financial advice.

How the New Hampshire Estate Tax Calculation Works

The calculation begins by adding five asset categories: real property, financial accounts, retirement accounts and annuities, life insurance owned by the decedent, and business interests or other property.

Gross Estate=Real Property+Financial Assets+Retirement Assets+Life Insurance+Business and Other Property\text{Gross Estate}=\text{Real Property}+\text{Financial Assets}+\text{Retirement Assets}+\text{Life Insurance}+\text{Business and Other Property}

The calculator then estimates administration costs. The entered attorney and administrator fee percentage is applied to gross estate minus debts, with that fee base floored at zero. Probate Court filing and other costs are added afterward.

Administration Costs=max⁡(Gross Estate−Debts,0)×Fee Rate100+Court Costs\text{Administration Costs}=\max(\text{Gross Estate}-\text{Debts},0)\times\frac{\text{Fee Rate}}{100}+\text{Court Costs}

Debts, funeral expenses, administration costs, and casualty or theft losses are deducted from the gross estate. The calculator calls the remaining amount the net estate.

Net Estate=max⁡(Gross Estate−Debts−Funeral−Administration Costs−Losses,0)\text{Net Estate}=\max(\text{Gross Estate}-\text{Debts}-\text{Funeral}-\text{Administration Costs}-\text{Losses},0)

A spousal bequest receives the modeled marital deduction only if the decedent is marked married and the surviving spouse is a U.S. citizen or the QDOT option is selected. The deduction cannot exceed the net estate. The charitable deduction is limited to the amount remaining after the marital deduction.

Taxable Estate Before Gifts=max⁡(Net Estate−Marital Deduction−Charitable Deduction,0)\text{Taxable Estate Before Gifts}=\max(\text{Net Estate}-\text{Marital Deduction}-\text{Charitable Deduction},0)

For gifting calculations, the amount used per donee is capped at the calculator’s annual exclusion: $18,000 for 2024 and $19,000 for 2025 or 2026.

Gift Reduction=min⁡(Gift per Donee,Annual Exclusion)×Donees×Years\text{Gift Reduction}=\min(\text{Gift per Donee},\text{Annual Exclusion})\times\text{Donees}\times\text{Years}
Taxable Estate=max⁡(Taxable Estate Before Gifts−Gift Reduction,0)\text{Taxable Estate}=\max(\text{Taxable Estate Before Gifts}-\text{Gift Reduction},0)

Earlier taxable gifts are added to the taxable estate to create the federal base. DSUE entered from a predeceased spouse is added to the selected year’s federal basic exclusion.

Federal Base=Taxable Estate+Earlier Taxable Gifts\text{Federal Base}=\text{Taxable Estate}+\text{Earlier Taxable Gifts}
Applicable Federal Exclusion=Basic Exclusion+DSUE\text{Applicable Federal Exclusion}=\text{Basic Exclusion}+\text{DSUE}

If the federal base exceeds the applicable exclusion, the calculator applies its progressive federal schedule, with encoded rates from 18% through 40%. Federal estate tax equals schedule tax on the federal base minus schedule tax on the applicable exclusion. Otherwise, federal estate tax is $0.

Federal Estate Tax=max⁡(T(Federal Base)−T(Applicable Federal Exclusion),0)\text{Federal Estate Tax}=\max\left(T(\text{Federal Base})-T(\text{Applicable Federal Exclusion}),0\right)

GST tax is calculated separately at 40% of direct skips remaining after the GST exemption entered by the user. Because New Hampshire estate and inheritance taxes are both $0 in the model, total transfer tax is federal estate tax plus GST tax.

GST Tax=0.40×max⁡(Direct Skips−GST Exemption,0)\text{GST Tax}=0.40\times\max(\text{Direct Skips}-\text{GST Exemption},0)
Total Transfer Tax=Federal Estate Tax+GST Tax\text{Total Transfer Tax}=\text{Federal Estate Tax}+\text{GST Tax}

Worked Example

Consider the calculator’s 2025 example with $8,000,000 of real property, $6,000,000 of financial assets, $4,000,000 of retirement assets, and $2,000,000 of business interests. The gross estate is $20,000,000.

Enter $500,000 of debts, $20,000 of funeral expenses, a 2% attorney and administrator fee, and $400 of court costs. The fee base is $19,500,000, so the percentage fee is $390,000. Adding court costs gives administration costs of $390,400. Total deductions are $910,400, leaving a net and taxable estate of $19,089,600.

For 2025, the calculator uses a $13,990,000 federal basic exclusion. Its progressive schedule produces $7,581,640 of tentative tax on $19,089,600 and $5,541,800 of applicable credit. Federal estate tax is therefore $2,039,840. New Hampshire tax and GST tax are $0 in this example, so total transfer tax is $2,039,840.

Understanding the Calculator’s Assumptions and Results

Federal Exclusion and Headroom

The calculator uses federal basic exclusions of $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026. Entered DSUE increases the applicable exclusion. Remaining headroom is the applicable exclusion minus the federal base, with a floor of $0.

Headroom=max⁡(Applicable Federal Exclusion−Federal Base,0)\text{Headroom}=\max(\text{Applicable Federal Exclusion}-\text{Federal Base},0)

The tax-free ceiling displayed by the calculator equals the current gross estate plus this remaining headroom. County selection changes the displayed Probate Court venue, not the estate-tax calculation itself.

New Hampshire Spousal Waiver Share

If the decedent is marked married and issue or parents are marked as surviving, the calculator estimates the waiver share as $25,000 plus one-half of the net estate above $25,000. The result is capped at the net estate. If no issue or parents survive, the modeled waiver share is the entire net estate.

Waiver Share=min⁡(Net Estate,25000+0.5×max⁡(Net Estate−25000,0))\text{Waiver Share}=\min\left(\text{Net Estate},25000+0.5\times\max(\text{Net Estate}-25000,0)\right)

If the decedent is not marked married, the waiver-share result is zero. The calculator flags this New Hampshire rule for verification.

Small-Estate Test

The calculator’s small-estate test adds financial assets, retirement accounts, life insurance, and business or other property. If this personal-property total is $10,000 or less, the result is marked as a small estate. Real property is not included in that test. The $10,000 limit is flagged for verification in the calculator.

Gifting and Basis-Cost Estimate

Gifting mode searches for the smallest whole number of years that makes total modeled transfer tax $0. Maximum years can range from 1 through 100 and defaults to 40. The number-of-donees field is required in gifting mode and accepts values from 0 through 200; entering 0 produces no gifting reduction.

The calculator also estimates a basis-related cost for gifted assets. It multiplies the entered unrealized gain by the selected long-term capital gains rate and adds 3.8% when the NIIT checkbox is selected. Net benefit equals calculated transfer-tax savings minus this basis-cost estimate.

Basis Cost=Unrealized Gain×(LTCG Rate+Selected NIIT Rate)\text{Basis Cost}=\text{Unrealized Gain}\times(\text{LTCG Rate}+\text{Selected NIIT Rate})
Net Benefit=Transfer Tax Saved−Basis Cost\text{Net Benefit}=\text{Transfer Tax Saved}-\text{Basis Cost}

Most dollar inputs accept values from $0 through $100,000,000. The attorney and administrator fee percentage accepts 0 through 25. The long-term capital gains selector offers 0%, 15%, and 20%. Required selections, valid numeric ranges, and the acknowledgment are checked before results are shown.

Displayed dollar amounts are rounded to whole U.S. dollars. The effective transfer-tax rate is shown with two decimal places, while the displayed marginal rate uses no decimal places. Results depend on user-entered assumptions and the encoded rules, so actual legal or tax outcomes may differ.

Frequently Asked Questions

Does this calculator charge New Hampshire estate tax?

No. The calculator sets New Hampshire estate tax to $0 for its supported death years. It also sets New Hampshire inheritance tax to $0. Federal estate tax and GST tax are the tax components that can increase the calculator’s total transfer-tax result.

What federal exclusions does the calculator use?

The encoded basic exclusions are $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026. The calculator adds any DSUE entered by the user to the selected year’s amount before comparing the federal base with the applicable exclusion.

How does the calculator determine federal estate tax?

It adds earlier taxable gifts to the modeled taxable estate. If that federal base exceeds the applicable exclusion, the calculator applies its progressive federal schedule to both amounts and subtracts the exclusion-side schedule tax from the federal-base schedule tax. If the base does not exceed the exclusion, federal estate tax is $0.

How is the New Hampshire waiver share calculated?

For a married decedent with surviving issue or parents selected, the calculator uses $25,000 plus one-half of the net estate above $25,000, capped at the net estate. If neither issue nor parents survive, it uses the whole net estate. The calculator marks this rule for verification.

How does the marital deduction differ from the waiver share?

They are separate calculator outputs. The marital deduction reduces the modeled taxable estate when the decedent is married and the spouse is a U.S. citizen or a QDOT is selected. The waiver share is a separate New Hampshire spousal-share estimate based on marital status, net estate, and whether issue or parents survive.

What happens if gifting cannot eliminate the tax within the selected horizon?

The calculator reports that more than the selected maximum number of years would be required. It does not return a gifting period beyond the entered horizon. Because gifting reduces the federal taxable estate but not GST tax, a remaining GST amount can also prevent total transfer tax from reaching $0.

When does the calculator flag federal Form 706 as required?

The calculator flags Form 706 as required when the federal base exceeds the applicable federal exclusion. Its results also display a nine-month filing period and a six-month filing extension through Form 4768, while noting that the filing extension does not extend the payment deadline.
