Wyoming Estate Tax Calculator

Estimate the federal estate tax on a Wyoming decedent’s estate and confirm that Wyoming itself charges nothing. Wyoming repealed its estate tax for deaths on or after January 1, 2005 (VERIFY) and has no inheritance tax and no gift tax, so for 2024-2026 deaths Wyoming tax is $0. 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.

How it works

  • Wyoming has no estate or inheritance tax. Wyoming repealed its estate tax for deaths on or after January 1, 2005 (VERIFY exact date). There is no Wyoming inheritance tax for recent deaths and no gift tax, so only federal transfer taxes apply.
  • No portability (Wyoming). Wyoming has no state exclusion to port; only the federal DSUE ports.
  • Common-law state. Wyoming is a common-law state; this tool does NOT halve community property or apply a double step-up.
  • Federal estate tax applies above the federal basic exclusion using the unified 18% to 40% schedule; the federal GST applies at 40% to direct skips above the allocated GST exemption.
  • Spousal elective share. Wyoming elective share is one-half of the net estate (VERIFY).
  • Small estates. Simplified administration is available where the estate value is $50,000 or less; verify the current figure.
  • Binding factor names what controls the result: the federal exclusion, the federal unified schedule, or the GST.
  • Gifting mode uses the guarded bisection solver (60 expansions, 90 iterations, rounded up). Because only the federal exclusion applies, the solver targets that single exclusion.
  • Gifting is not free. Carryover basis loses the step-up; the deferred gain is netted against the tax saved.

What Is a Wyoming Estate Tax Calculator?

The Wyoming Estate Tax Calculator estimates federal transfer taxes after combining estate assets, subtracting modeled deductions and bequests, adding earlier taxable gifts, and applying the selected federal exclusion plus any entered DSUE. Wyoming estate and inheritance taxes remain $0 in the calculation, so federal estate tax and GST tax determine the modeled tax total.

The calculator has three modes. Estate mode estimates transfer tax on the entered estate. Headroom mode tests whether the estate profile produces tax and shows remaining federal exemption room. Gifting mode searches for the whole number of years of modeled annual-exclusion gifts needed to bring total calculated transfer tax to zero.

Year of deathFederal basic exclusion usedAnnual gift exclusion used
2024$13,610,000$18,000 per donee
2025$13,990,000$19,000 per donee
2026$15,000,000$19,000 per donee

How the Wyoming Estate Tax Calculation Works

The calculation begins by adding real property, bank and brokerage accounts, retirement accounts and annuities, includible life insurance, and business interests or other property.

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

Administration costs include the attorney and executor fee plus District Court filing and other entered costs. Although the field label refers to a percentage of net estate, the code applies that percentage to gross estate minus debts, with the fee base floored at zero.

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

The calculator then subtracts debts, funeral expenses, administration costs, and casualty or theft losses. The net estate cannot fall below zero.

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

A marital deduction is allowed only when the decedent is marked married and the surviving spouse is a U.S. citizen or the bequest passes to a QDOT. The deduction cannot exceed the net estate. The charitable deduction is limited to what remains after the marital deduction.

For gifting calculations, the effective gift per donee is capped at the coded annual exclusion for the selected year.

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

Earlier taxable gifts are added to the taxable estate to form the federal base. Entered DSUE is added to the federal basic exclusion.

B=Taxable Estate+Earlier Taxable GiftsB=\text{Taxable Estate}+\text{Earlier Taxable Gifts}
E=Federal Basic Exclusion+DSUEE=\text{Federal Basic Exclusion}+\text{DSUE}

If the federal base exceeds the applicable exclusion, the calculator applies its progressive federal schedule, with rates from 18% through 40%. Let SF represent that coded schedule.

Federal Estate Tax=max⁡(SF(B)−SF(E),0)\text{Federal Estate Tax}=\max\left(S_F(B)-S_F(E),0\right)

Wyoming estate tax and inheritance tax are both set to zero. Federal GST tax is calculated separately from direct skips remaining after the entered GST exemption.

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 a hypothetical 2025 estate with $10,000,000 of real property, $5,000,000 of financial assets, and $5,000,000 of retirement assets. Gross estate is $20,000,000. Assume $300,000 of debts, $20,000 of funeral expenses, a 2% attorney and executor fee, $400 of court costs, and no other deductions.

The fee base is $19,700,000. A 2% fee equals $394,000, and adding $400 of court costs produces $394,400 of administration costs. Total deductions are $714,400, leaving a net estate of $19,285,600.

With no marital deduction, charitable deduction, prior taxable gifts, DSUE, gifting reduction, or GST tax, the federal base is $19,285,600. The 2025 applicable exclusion is $13,990,000. The calculator’s schedule produces $7,660,040 of tentative tax and $5,541,800 of applicable credit. Federal estate tax is therefore $2,118,240. Wyoming tax is $0, so total transfer tax is $2,118,240 and the displayed effective rate is 10.59%.

How to Use the Wyoming Estate Tax Calculator

  1. Select estate tax, larger-estate headroom, or years-of-gifting mode.
  2. Choose the year of death from 2024, 2025, or 2026.
  3. Select the Wyoming county of domicile used for the displayed District Court venue.
  4. Enter real property, financial accounts, retirement assets, life insurance, and business or other property.
  5. Enter debts, funeral expenses, the attorney and executor fee percentage, court costs, and casualty or theft losses.
  6. Set marital status and, when relevant, spouse citizenship or QDOT status. Enter spousal and charitable bequests.
  7. Enter earlier taxable gifts, federal DSUE, direct skips, and any GST exemption allocated.
  8. For gifting analysis, enter the number of donees, annual gift per donee, unrealized gain, heirs’ capital-gains rate, NIIT choice, and maximum years to test.
  9. Check the required acknowledgment and select the calculation button.

Estate mode displays total transfer tax as the main result. Headroom mode returns a tax-status verdict with federal headroom and a tax-free ceiling. Gifting mode shows the calculated number of years, “None needed” when baseline tax is already zero, or a message that more than the selected maximum years would be needed.

Important Assumptions and Result Details

The detailed output shows gross estate, deductions, net estate, marital and charitable deductions, planned gifting, taxable estate, federal tentative tax, federal credit, federal estate tax, Wyoming estate tax, Wyoming inheritance tax, GST taxable amount, GST tax, total transfer tax, effective rate, marginal federal rate, and the calculator’s stated binding factor.

Federal Headroom and Tax-Free Ceiling

Federal headroom is the applicable federal exclusion minus the federal base, with negative values replaced by zero. The calculator adds that headroom to gross estate to produce its displayed tax-free ceiling.

Federal Headroom=max⁡(E−B,0)\text{Federal Headroom}=\max(E-B,0)
Tax-Free Ceiling=Gross Estate+Federal Headroom\text{Tax-Free Ceiling}=\text{Gross Estate}+\text{Federal Headroom}

The effective transfer-tax rate divides total transfer tax by gross estate. If gross estate is zero, the calculator returns a zero effective rate. Currency values are rounded to the nearest whole dollar for display, while the effective rate is shown with two decimal places.

Effective Rate={Total Transfer TaxGross Estate,if Gross Estate>00,otherwise\text{Effective Rate}=\begin{cases}\frac{\text{Total Transfer Tax}}{\text{Gross Estate}},&\text{if Gross Estate}>0\\0,&\text{otherwise}\end{cases}

The displayed marginal federal rate is 40% whenever the federal base exceeds the applicable exclusion. Otherwise, it is 0%. This is the calculator’s coded display rule.

Wyoming Tax, Venue, and Filing Results

The calculator always sets Wyoming estate tax and Wyoming inheritance tax to $0. Its text states that Wyoming’s former estate tax was repealed for deaths on or after January 1, 2005, while explicitly flagging that exact date for verification. The Wyoming estate-tax return result is always “No.”

The selected county determines the District Court venue shown in the results and regional note. It does not change the federal tax arithmetic. The calculator contains county choices for Wyoming and an “Other Wyoming county” option.

The federal Form 706 indicator changes to “Yes” when the federal base exceeds the applicable federal exclusion. The calculator also displays a nine-month federal filing deadline and a six-month filing extension message. Those are coded informational messages and should be independently verified before reliance.

Small-Estate and Elective-Share Indicators

The small-estate indicator uses a coded $50,000 threshold that the calculator marks for verification. The actual test adds financial accounts, retirement assets, life insurance, and business or other property. Real property and estate deductions do not enter this specific calculation.

Small-Estate Test Amount=Financial+Retirement+Life Insurance+Other Property\text{Small-Estate Test Amount}=\text{Financial}+\text{Retirement}+\text{Life Insurance}+\text{Other Property}

For a married decedent, the calculator displays an elective-share estimate equal to one-half of the calculated net estate. Its own text marks the Wyoming elective-share figure for verification.

Elective Share Estimate=0.50×Net Estate\text{Elective Share Estimate}=0.50\times\text{Net Estate}

The tool identifies Wyoming as a common-law state and states that it does not halve community property or apply a double step-up. Entered asset values therefore flow into the gross-estate calculation without either adjustment.

How the Gifting Solver Works

The gifting solver searches for the first whole number of years that reduces total calculated transfer tax to zero. It expands its testing interval up to 60 times and then performs 90 bisection iterations before rounding the result upward. The user-entered maximum testing horizon is limited to 1 through 200 years.

The number-of-donees field is required in gifting mode, although zero remains inside the field’s numeric range and passes the range check. With no positive donee count, the gifting reduction is zero.

The effective gift per donee cannot exceed the calculator’s annual exclusion. An entered gift above that amount is not automatically added to earlier taxable gifts. The earlier-taxable-gifts field is handled separately.

Gifting reduces the modeled taxable estate but does not reduce the separate direct-skips input. A remaining GST amount can therefore prevent the solver from reaching zero total transfer tax even when federal estate tax falls to zero.

Three-Year Projection and Heir Results

The results include tax remaining after one, two, and three years of gifting plus cumulative tax saved after three years. When the effective annual gift is greater than zero, those projections recalculate the estate with one, two, and three years of gift reductions.

The “Net to other heirs” amount equals net estate minus the modeled marital deduction, charitable deduction, and total transfer tax, with a floor of zero. The gifting reduction is not separately subtracted from this displayed heir amount.

Net to Other Heirs=max⁡(Net Estate−Marital−Charitable−Transfer Tax,0)\text{Net to Other Heirs}=\max(\text{Net Estate}-\text{Marital}-\text{Charitable}-\text{Transfer Tax},0)

Unrealized Gain Input in This Version

The form accepts unrealized gain in gifted assets, a 0%, 15%, or 20% long-term capital-gains rate, and an optional 3.8% NIIT setting. However, the calculation result object does not carry the unrealized-gain value into the result-rendering calculation.

As the supplied code is written, the displayed deferred capital-gains amount resolves to $0 and the displayed net-benefit value also resolves to $0, even when an unrealized-gain amount is entered. The explanatory basis note likewise displays a $0 modeled deferred-gain amount.

Most monetary inputs accept values from $0 through $100,000,000. The attorney and executor fee accepts 0% through 25%. Donees accept 0 through 200, and the maximum-years field accepts 1 through 200. County selection and the acknowledgment are required before a calculation can complete.

This calculator provides an estimate based on user-entered assumptions and the exact logic implemented in the tool. Actual tax liability, filing duties, probate procedures, deductions, gifting consequences, and spousal rights may differ. The Wyoming repeal date, elective-share treatment, and small-estate figure are specifically marked for verification and should not be treated as legal, tax, or financial advice.

Frequently Asked Questions

Does this calculator charge Wyoming estate tax?

No. Wyoming estate tax is hard-coded as $0 for all supported 2024 through 2026 death years. Wyoming inheritance tax is also $0. The interface says the former estate tax was repealed for deaths on or after January 1, 2005, but it flags that exact date for verification.

What federal estate tax exclusions does the calculator use?

It uses $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026. Any DSUE entered from a predeceased spouse is added to the selected year’s basic exclusion before the federal tax calculation.

How does DSUE affect the Wyoming calculation?

DSUE affects only the federal applicable exclusion. The calculator has no Wyoming exclusion to increase or port because Wyoming estate tax is set to zero. Its result section therefore describes Wyoming portability as not applicable.

How does the calculator handle marital and charitable deductions?

The marital deduction is allowed when the decedent is marked married and the surviving spouse is a U.S. citizen or a non-citizen spouse’s bequest passes to a QDOT. It is capped at the net estate. The charitable deduction is then capped at the amount left after the marital deduction.

How is federal GST tax calculated?

The calculator subtracts the entered GST exemption from direct skips to grandchildren or later generations. A negative remainder becomes zero. Any positive taxable direct-skip amount is multiplied by 40%, and that GST tax is added to federal estate tax when total transfer tax is calculated.

How does the calculator determine the years of gifting needed?

It repeatedly tests larger gifting periods until zero total transfer tax becomes reachable or the maximum horizon is exceeded. If reachable, it narrows the result through bisection and rounds upward to a whole year. A remaining GST liability can keep the result from reaching zero.

How does the calculator decide whether the estate is small?

The code adds financial accounts, retirement assets, includible life insurance, and business or other property and compares that total with $50,000. Real property is excluded from this specific internal test. The calculator marks the $50,000 figure for verification.
