South Carolina Estate Tax Calculator

Estimate the federal estate tax on a South Carolina decedent’s estate and confirm that South Carolina itself charges nothing. South Carolina has no estate tax (the former pick-up tax is $0 for deaths after 2004), no inheritance tax, and no gift tax, so for 2024-2026 deaths South Carolina 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.

South Carolina rules this calculator enforces: NO state estate tax for recent deaths (the former pick-up estate tax was tied to the federal state death tax credit under IRC 2011 and is $0 for deaths after 2004; VERIFY effective repeal date), so no South Carolina estate tax return is filed; no inheritance tax; no gift tax; common-law (equitable distribution) state, not community property; spousal elective share of one-third of the net estate (S.C. Code 62-2-201; VERIFY); small-estate affidavit where the value of the entire estate less liens is $25,000 or less (S.C. Code 62-3-1201; VERIFY); probate venue in the Probate Court of the county of domicile (46 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

  • South Carolina has no estate or inheritance tax. The former South Carolina estate tax was a pick-up tax tied to the federal state death tax credit under IRC 2011; it is $0 for deaths after 2004 (VERIFY effective repeal date). There is no South Carolina inheritance tax and no gift tax, so only federal transfer taxes apply.
  • 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.
  • No community property. South Carolina 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 South Carolina state exclusion to port.
  • Elective share. A surviving spouse may elect one-third of the net estate under S.C. Code 62-2-201 (VERIFY); modeled here on the net estate.
  • Small estates. The small-estate affidavit is available where the value of the entire estate less liens is $25,000 or less; verify the current figure.
  • Binding factor names what controls the result: the federal basic 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 South Carolina Estate Tax Calculator?

This South Carolina estate tax calculator estimates federal estate tax and federal GST tax for a South Carolina estate while setting South Carolina estate and inheritance tax to $0. It uses entered assets, deductions, prior taxable gifts, DSUE, direct skips, and gifting assumptions to calculate total transfer tax and federal exclusion headroom.

The calculator has three modes. Estate mode calculates the transfer tax on the values entered. Headroom mode reports whether the estate profile produces tax and how much federal exclusion remains. Gifting mode searches for the number of modeled annual-exclusion gifting years needed to bring calculated total transfer tax to zero.

The county selection is used for the displayed South Carolina Probate Court venue. It does not change the federal estate-tax calculation.

How the South Carolina Estate Tax Calculation Works

The calculator first adds five asset categories: real property, bank and investment accounts, retirement accounts and annuities, life insurance, and business or other property.

G=R+F+T+L+BG=R+F+T+L+B

Here, G is gross estate, R is real property, F is financial accounts, T is retirement assets, L is life insurance entered in the calculator, and B is business interests, personal property, and other assets.

Administration costs combine an entered percentage fee with Probate Court and other entered costs. Although the input label describes the attorney and executor fee as a percentage of the net estate, the code actually applies it to gross estate minus debts, with a minimum base of zero.

A=max⁡(G−D,0)×p100+CA=\max(G-D,0)\times\frac{p}{100}+C

The calculator then subtracts debts, funeral expenses, administration costs, and casualty or theft losses to determine the net estate.

N=max⁡(G−D−Fu−A−Ls,0)N=\max(G-D-F_u-A-L_s,0)

A spouse 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 is capped at the net estate. The charitable deduction is then capped at the amount remaining after the marital deduction.

Annual-exclusion gifting is subtracted next. The calculator uses $18,000 per donee for 2024 and $19,000 per donee for 2025 and 2026. If a larger annual gift is entered, only the applicable exclusion amount is used for this estate-reduction calculation.

Gr=min⁡(g,e)×n×yG_r=\min(g,e)\times n\times y

Here, Gr is the modeled gifting reduction, g is the entered annual gift per donee, e is the encoded annual exclusion, n is the number of donees, and y is the number of gifting years.

TE=max⁡(N−M−Ch−Gr,0)TE=\max(N-M-C_h-G_r,0)

The federal tax base adds earlier taxable gifts to that taxable-estate amount.

BF=TE+PB_F=TE+P

The federal applicable exclusion equals the basic exclusion for the selected year plus entered DSUE. The calculator uses $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026.

EF=EB+DSUEE_F=E_B+DSUE

If the federal base exceeds that exclusion, the calculator applies its progressive federal schedule to both amounts. Federal estate tax is the schedule tax on the federal base minus the schedule tax on the applicable exclusion.

TF=max⁡(SF(BF)−SF(EF),0)T_F=\max\left(S_F(B_F)-S_F(E_F),0\right)

The encoded federal schedule progresses from 18% through 40%. South Carolina estate tax and South Carolina inheritance tax are both fixed at $0 in the calculation.

Federal GST tax is calculated separately from direct skips.

TGST=0.40×max⁡(Direct Skips−GST Exemption,0)T_{GST}=0.40\times\max(\text{Direct Skips}-\text{GST Exemption},0)
TTotal=TF+TGSTT_{Total}=T_F+T_{GST}

Worked Example

Consider a hypothetical 2025 estate with $9,000,000 of real property, $6,000,000 of financial assets, $4,000,000 of retirement assets, and $2,000,000 of business interests. Enter $500,000 of debts, $20,000 of funeral costs, a 2% attorney and executor fee, and $400 of court costs.

The gross estate is $21,000,000. Administration costs equal ($21,000,000 − $500,000) × 2% + $400, or $410,400. Total modeled deductions are $930,400, leaving a net estate of $20,069,600 when no other deductions apply.

With no marital deduction, charitable deduction, gifting, or prior taxable gifts, the federal base is $20,069,600. The encoded schedule produces tentative tax of $7,609,440. The schedule tax on the calculator’s $13,990,000 federal exclusion is $5,541,800, leaving federal estate tax of $2,067,640. With no GST, total transfer tax is also $2,067,640.

How to Use the South Carolina Estate Tax Calculator

  1. Choose estate-tax calculation, larger-estate testing, or the gifting-years solver.
  2. Select the year of death from 2024, 2025, or 2026 and choose the South Carolina county of domicile.
  3. Enter real property, financial accounts, retirement assets, life insurance, and business or other property.
  4. Enter debts, funeral costs, the attorney and executor fee percentage, Probate Court costs, and casualty or theft losses.
  5. Enter any spouse and charitable bequests. Select the spouse citizenship or QDOT options when applicable.
  6. Enter earlier taxable gifts, DSUE from a predeceased spouse, direct skips, and the GST exemption allocation.

  8. Select the required acknowledgment checkbox and use the calculation button.

In estate mode, the main result is total transfer tax. The detailed output also shows federal tax, South Carolina tax amounts, GST, federal headroom, deductions, taxable estate, effective rate, filing indicators, estimated amounts received by other heirs, succession information, and gifting projections. Currency values are displayed as whole dollars, while the effective rate uses two decimal places.

Important Assumptions and Calculator Details

South Carolina Tax Is Fixed at Zero

The implemented calculation always sets both South Carolina estate tax and South Carolina inheritance tax to $0. Earlier taxable gifts therefore affect only the federal estate-tax base. DSUE also applies only to the federal exclusion because the calculator has no South Carolina estate-tax exclusion to increase or port.

Federal Headroom and Tax-Free Ceiling

Federal headroom equals the applicable federal exclusion minus the federal base, with negative amounts replaced by zero. The calculator’s tax-free ceiling adds this remaining headroom to the current gross estate.

H=max⁡(EF−BF,0)H=\max(E_F-B_F,0)
Cmax=G+HC_{max}=G+H

This ceiling assumes the other values in the estate profile remain unchanged. It is not a separate appraisal or forecast of future estate value.

Small-Estate Indicator Uses Personal Property in the Code

The calculator’s explanatory text describes a $25,000 small-estate rule based on estate value less liens. However, the implemented small-estate indicator does something narrower: it adds financial accounts, retirement assets, life insurance, and business or other personal property, excludes real property, and checks whether that sum is $25,000 or less. It does not subtract liens in this test.

Because calculator code is the controlling behavior, the displayed small-estate badge follows that personal-property calculation. The underlying $25,000 South Carolina figure is itself marked for verification in the calculator.

Spousal Elective-Share Display

If the decedent is marked married, the calculator displays an elective-share estimate equal to one-third of the calculated net estate. The calculator flags the underlying South Carolina rule for verification, so this value should not be treated as a legal determination of a surviving spouse’s rights.

Elective Share=N3\text{Elective Share}=\frac{N}{3}

Gifting Solver Behavior

The gifting solver searches for the first whole number of years that makes calculated total transfer tax zero, up to the entered maximum. The maximum-years field accepts values from 1 through 100. The solver expands its search and then uses repeated bisection before rounding the required years upward.

The donee field is described as requiring at least one donee in gifting mode, but the implemented validation permits a numeric value of 0 through 200. A zero entry therefore passes the range test even though it creates no gifting reduction.

GST is not reduced by annual-exclusion gifting because direct skips and GST exemption remain unchanged. If GST alone keeps total transfer tax above zero, the gifting solver cannot eliminate the full tax through its estate-reduction calculation.

Capital-Gains Output Limitation

The form collects unrealized gain in gifted assets, a 0%, 15%, or 20% long-term capital-gains-rate selection, and an optional 3.8% NIIT assumption. However, the result object used by the display does not return the entered appreciation value. The displayed deferred capital-gains cost therefore formats as $0, and the displayed net-benefit figure does not correctly incorporate that entered gain in this revision.

Input Limits and Validation

Most money inputs accept values from $0 through $100,000,000. The attorney and executor fee accepts 0% through 25%. The donee count accepts 0 through 200, and maximum gifting years accepts 1 through 100. The calculator also requires a death year, county, capital-gains-rate selection, and acknowledgment checkbox before producing results.

Frequently Asked Questions

Does this calculator charge South Carolina estate tax?

No. The implemented South Carolina estate-tax amount is always $0 for the supported 2024 through 2026 death years. The calculator also sets South Carolina inheritance tax to $0. Its tax total therefore comes from federal estate tax and any calculated federal GST tax.

What federal estate-tax exclusions does the calculator use?

The code uses a federal basic exclusion of $13,610,000 for 2024, $13,990,000 for 2025, and $15,000,000 for 2026. Any DSUE amount entered by the user is added to the selected year’s basic exclusion before the federal estate-tax calculation.

How are prior taxable gifts treated?

Earlier taxable gifts are added to the federal tax base after the calculator determines the estate remaining after deductions and modeled annual-exclusion gifting. They do not increase the displayed gross estate. Because they increase the federal base, they can reduce the calculator’s remaining federal headroom.

How is the effective transfer-tax rate calculated?

The effective rate equals total transfer tax divided by gross estate. Total transfer tax can include federal estate tax and GST because the calculator’s South Carolina estate and inheritance taxes are both zero. If gross estate is zero, the calculator returns an effective rate of zero instead of dividing by zero.

Effective Rate=TTotalG×100%\text{Effective Rate}=\frac{T_{Total}}{G}\times100\%

When does the calculator flag federal Form 706?

The calculator marks federal Form 706 as required when its federal tax base exceeds the applicable federal exclusion. It always displays the South Carolina estate-tax return as not required. These are calculator decision rules and should not be treated as an independent determination of every possible filing obligation.

How does the calculator estimate annual gifting?

It uses the smaller of the entered annual gift per donee and the calculator’s annual exclusion, then multiplies that value by the donee count and number of years. The encoded exclusion is $18,000 for 2024 and $19,000 for both 2025 and 2026.

What does “net to other heirs” mean in the results?

The calculator starts with the net estate, subtracts the allowed marital deduction, charitable deduction, and total transfer tax, and floors the result at zero. Administration costs have already been deducted when the net estate is calculated, so they are not subtracted a second time in this output.
