California Estate Tax Calculator

Estimate the federal estate tax on a California decedent’s estate and confirm that California itself charges nothing. California has no estate tax, no inheritance tax and no gift tax; its old statute imposed only a pick-up tax equal to the federal state death tax credit, which no longer exists. California’s distinctive rules that this calculator does model are community property (only the decedent’s half enters the gross estate, and the spouse’s half passes outside the estate outright) 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.

California rules this calculator enforces: no state estate tax (Rev. & Tax. Code 13301-13308 imposed only the federal state death tax credit pick-up, which is zero for deaths after 2004, so no California estate tax return is filed); no inheritance tax; no gift tax; community property state (Fam. Code 760) so only the decedent’s one-half of community assets enters the gross estate and the surviving spouse’s half passes outside the estate outright (Fam. Code 100), with a double basis step-up on community assets at death (IRC 1014(b)(6)); NO statutory elective share — the spouse’s protection is the outright community half plus the intestate share of separate property (Prob. Code 6401); small-estate affidavit where personal property is $184,500 or less (Prob. Code 13100; verify current adjusted figure); probate venue in the Superior Court of the county of domicile.
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

  • California charges nothing. The California estate tax statute imposed only a pick-up tax equal to the federal state death tax credit; that credit was eliminated for deaths after 2004, so the California estate tax is $0 and no California estate tax return is filed. There is no California inheritance tax and no California 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.
  • Community property is halved. California is a community property state, so only the decedent’s one-half of community assets enters the gross estate; the surviving spouse’s half passes outside the estate outright and community assets receive a double basis step-up at death (IRC 1014(b)(6)).
  • No elective share. California has no statutory elective share; the spouse’s protection is the outright community half plus the intestate share of separate property (Prob. Code 6401).
  • Portability is federal only. A surviving spouse may inherit the unused federal exclusion (DSUE) with a timely Form 706 election; there is no California state exclusion to port.
  • Small estates skip full probate. The affidavit procedure under Prob. Code 13100 is available where personal property is $184,500 or less; verify the current adjusted 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 the California Estate Tax Calculator?

The California Estate Tax Calculator is a planning tool that estimates federal transfer taxes for an estate connected to California. The code assigns $0 to California estate tax and California inheritance tax. It then calculates possible federal estate tax and federal generation-skipping transfer tax using the values and assumptions entered by the user.

A California Estate Tax Calculator estimates the decedent’s gross and taxable estate, compares the federal tax base with the programmed federal exclusion, and calculates federal estate tax when that base exceeds the exclusion. It also treats only one-half of entered community property as part of the decedent’s gross estate.

The calculator has three modes. You can estimate tax on the current estate, test whether a larger estate profile would produce tax, or estimate the years of annual-exclusion gifting needed to reduce total calculated transfer tax to zero. Results also include probate venue, a small-estate affidavit test, Form 706 status, exclusion headroom, and amounts passing to heirs.

How the California Estate Tax Calculator Formula Works

California community property receives special treatment in the code. If the community-property checkbox is selected, only one-half of the amount entered as total community property enters the gross estate. The other entered asset categories are added as separate property.

Community Share=0.5×Total Community Property\text{Community Share}=0.5\times\text{Total Community Property}
Gross Estate=Community Share+Real Property+Financial+Retirement+Life Insurance+Business/Other\text{Gross Estate}=\text{Community Share}+\text{Real Property}+\text{Financial}+\text{Retirement}+\text{Life Insurance}+\text{Business/Other}

Administration costs include the entered court costs plus an attorney and personal representative fee calculated on the gross estate after debts, with that fee base never falling below zero.

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

The marital deduction is available in the calculation only when the decedent is marked married and the spouse is a U.S. citizen or the bequest passes to a QDOT. The deduction cannot exceed the net estate. The charitable deduction is then limited to the amount remaining after the marital deduction.

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. DSUE is added to the selected year’s federal basic exclusion. Federal estate tax is calculated only when this federal base exceeds the total applicable exclusion.

Federal Base=Taxable Estate+Earlier Taxable Gifts\text{Federal Base}=\text{Taxable Estate}+\text{Earlier Taxable Gifts}
Federal Estate Tax=Schedule Tax(Federal Base)−Schedule Tax(Applicable Exclusion)\text{Federal Estate Tax}=\text{Schedule Tax(Federal Base)}-\text{Schedule Tax(Applicable Exclusion)}

The programmed unified schedule ranges from 18% to 40%. GST tax is separate and equals 40% of direct skips above 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)

For a worked example, use the calculator’s 2025 taxable-estate test. Enter $9,000,000 of separate real property, $6,000,000 of financial assets, $4,000,000 of retirement assets, and $2,000,000 of business interests. Gross estate equals $21,000,000. With $500,000 of debts, $20,000 of funeral costs, a 2% fee, and $400 of court costs, administration expense is $410,400.

Total deductions are $930,400, producing a net estate of $20,069,600. A $69,600 charitable deduction reduces the taxable estate to $20,000,000. The code calculates $7,945,800 of tentative federal tax and subtracts $5,541,800 of tax on the $13,990,000 exclusion. Federal estate tax is $2,404,000. California tax is $0, so total transfer tax is $2,404,000 when no GST tax applies.

How to Use the California Estate Tax Calculator: Step by Step

  1. Choose whether to calculate estate tax, test a larger estate, or solve for years of gifting needed to eliminate the calculated tax.
  2. Select the year of death and California county of domicile. The year controls the programmed federal exclusion and annual gift exclusion, while the county identifies the Superior Court venue.
  3. If applicable, select the community-property option and enter both halves of the community property. Then enter separate real property, financial accounts, retirement assets, life insurance, and business or other property.
  4. Enter debts, funeral expenses, the attorney and personal representative fee percentage, Superior Court costs, and casualty or theft losses.
  5. Enter marital information, including whether there is a surviving spouse, U.S. citizenship or QDOT status, the spouse bequest, and any charitable bequest.
  6. Enter earlier taxable gifts, DSUE portability, direct skips, and allocated GST exemption if those items apply to the estate.
  7. For gifting analysis, enter the number of donees, gift per donee, unrealized gain, heirs’ capital-gains rate, NIIT selection, and maximum years to test.
  8. Check the acknowledgment box and calculate. The tool checks required fields and numerical ranges before displaying the results.

The results show federal estate tax, California tax, GST tax, total transfer tax, the effective rate on the gross estate, exclusion headroom, taxable estate, net amount to other heirs, the spouse’s community half, probate venue, small-estate affidavit status, and the calculator’s Form 706 determination. Gifting mode also shows the annual gift amount, years required, and three-year tax projection.

What Your California Estate Tax Calculator Result Means

Community Property Changes the Gross Estate

The calculator treats California as a community-property state. When the community-property option is active, it includes only 50% of the entered community-property total in the decedent’s gross estate. It separately displays the same amount as the surviving spouse’s community half outside the estate. Do not also enter those community assets in the separate-property fields.

The Calculator Uses These Programmed Thresholds

ItemValue Used by the Calculator
2024 federal basic exclusion$13,610,000
2025 federal basic exclusion$13,990,000
2026 federal basic exclusion$15,000,000
2024 annual gift exclusion$18,000 per donee
2025 annual gift exclusion$19,000 per donee
2026 annual gift exclusion$19,000 per donee
Federal GST rate40%
California estate tax$0
California inheritance tax$0
Small-estate personal property limit$184,500

The small-estate test uses only financial accounts, retirement assets, includible life insurance, and business or other property. Separate real property and the entered community-property amount are not included in that particular calculation. The tool itself advises users to verify the current small-estate threshold before relying on it.

There Is No Elective Share Calculation

The calculator does not calculate a California statutory elective share. Instead, it displays the surviving spouse’s one-half of entered community property as passing outside the estate. It also notes that community property may receive a double basis step-up, but that basis adjustment is not included in the estate-tax calculation.

Understand the Gifting Mode Limitation

For estate reduction, the calculator uses the smaller of the entered annual gift per donee and the programmed annual exclusion. It multiplies that amount by the number of donees and years. The solver searches for the first whole number of years that reduces total calculated transfer tax to zero within the selected maximum of up to 100 years.

The form also accepts unrealized gain, a long-term capital-gains rate, and an NIIT choice. However, the current result code references the unrealized-gain value from a result property that the tax calculation does not return. As coded, the displayed deferred capital-gains cost and net-benefit figures therefore format as $0. These inputs do not change the federal estate, California, or GST tax calculation.

This calculator provides estimates only. Actual estate-tax liability, federal filing duties, portability, deductions, asset ownership, valuation, GST treatment, probate procedure, basis, and gifting consequences can depend on facts the tool does not model. Tax and probate laws can also change. Do not treat the calculator’s output as legal, tax, or financial advice.

Frequently Asked Questions

Does California have an estate tax?

The calculator assigns $0 to California estate tax. It also assigns $0 to California inheritance tax. An estate can still produce federal estate tax or federal GST tax under the calculator’s formulas. For that reason, the results separate California’s $0 amount from any federal transfer taxes calculated on the estate.

How does community property affect California estate tax calculations?

The calculator includes only one-half of entered community property in the decedent’s gross estate. If $2,000,000 is entered as total community property, $1,000,000 enters the gross estate and $1,000,000 is shown as the surviving spouse’s community half outside the estate. Separate assets are then added normally.

What federal estate tax exemption does the calculator use?

The calculator uses $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026. Any entered DSUE amount is added to that basic exclusion. Earlier taxable gifts are added to the taxable estate when the tool creates the federal tax base used for its estate-tax comparison.

How does the calculator determine whether Form 706 is required?

The calculator marks Form 706 as required when its federal base exceeds the total applicable exclusion. The federal base is the calculated taxable estate plus earlier taxable gifts. The tool displays a deadline of nine months after death and notes a six-month filing extension, but its filing flag is a simplified calculator rule.

How does the California small-estate affidavit calculation work?

The calculator marks the affidavit as available when defined personal property is $184,500 or less. For this test, it adds financial accounts, retirement accounts, includible life insurance, and business or other property. It does not include the separate-real-property field or community-property amount in that specific eligibility calculation.

How many years of gifting does the calculator test?

The user can set a maximum from 1 to 100 years. Gifting mode searches within that horizon for the first whole number of years that makes the calculator’s total transfer tax zero. If annual-exclusion gifting cannot eliminate the tax within the selected period, the result reports that more than the maximum years are needed.

How accurate is the California Estate Tax Calculator?

The calculator accurately follows the formulas and thresholds programmed into its code, but the result is still an estimate. Real estates may involve ownership details, trusts, valuations, deductions, elections, filing rules, basis questions, or tax issues that are not represented. The programmed 2024 to 2026 figures should also be verified before use.
