Mississippi Estate Tax Calculator (2026 Exemption Limits & Inheritance Liabilities)

Mississippi charges no estate tax and no inheritance tax, one of a solid block of Deep South states that take nothing at death.

That places Mississippi in the larger group of 38 states that repealed or never adopted a separate estate tax, as opposed to the 12 states that still run one alongside the federal system.

The practical result is that a Mississippi estate's tax exposure depends entirely on federal law, not state statute. That means state legislative changes in Mississippi have no bearing on the calculation, unlike in states that still set their own exemption and rate schedule.

It also means the calculation is unusually stable for Mississippi families: the number to watch is the federal exemption, published and adjusted at the national level, not a Mississippi statute that could shift with a single legislative session.

Real property is the one exception worth flagging: a home or land Mississippi residents own in a state that does levy its own estate tax stays subject to that state's rules, no matter how simple the Mississippi side of the math is, or that Mississippi is a Deep South, Gulf Coast state.

There is no Mississippi estate tax statute, so there is no exemption to clear and no rate schedule to walk. The calculator confirms that rather than computing against a threshold, and the state tax line is $0 at every estate size.

1. Value the gross estate. Fair market value at the date of death of all real property, business interests, securities, cash, and life insurance proceeds the decedent owned.
2. Subtract allowable deductions. Debts, administrative expenses, qualifying charitable bequests, and the unlimited marital deduction come off the gross figure. This is bookkeeping here rather than tax math, since no state rate is applied to the result.
3. Look Mississippi up in the state table. It is not among the twelve states that impose an estate tax, so no exemption threshold or bracket schedule is loaded.
4. Return $0. The net estate passes to beneficiaries with no Mississippi reduction, whether it is $500,000 or $50,000,000.

The federal estate tax is a separate return with its own exemption, above $15,000,000 per individual for 2026, and this calculator does not compute it. It also does not carry over a deceased spouse's unused federal exemption, add back lifetime taxable gifts, or apply the generation-skipping transfer tax.

1. Start with the gross estate. This example uses a $5,000,000 gross estate: the fair market value of all real property, business interests, equities, cash, and life insurance the decedent owned at death, before deductions.
2. Check Mississippi's estate tax status. Mississippi is one of the 38 states with no separate state-level estate tax, so there is no state exemption threshold or bracket schedule to apply.
3. Compute the state estate tax due. Because Mississippi taxes no estates at any size, the calculator returns $0.00 in state tax. A $5,000,000 estate and a $50,000,000 estate both owe Mississippi nothing.
4. Distribute the net estate. With no state tax subtracted, the full $5,000,000.00 gross estate passes to beneficiaries as the net estate distributed.
5. What this excludes. This is Mississippi's state-level result only; federal estate tax is computed separately against the $15,000,000+ federal exemption per individual for 2026 on IRS Form 706.

Mississippi's rate table has no exemption and no brackets, so every row of the sweep is identical. The content that earns its place here is what the zero is worth in comparison and what the calculator's other inputs do when there is no rate to apply them to.

The sweep does not move. The engine returns $0.00 at a $1,000,000 estate, at $5,000,000 and at $15,000,000. The exemption threshold output reads $0.00 in every case, the taxable estate above exemption reads $0.00, and the net value distributed to heirs equals the full estate: $5,000,000.00 and $15,000,000.00 respectively. Adding another $1,000,000 of estate value adds $0.00 of Mississippi tax at any point on the curve, which is the only marginal figure in this family that does not depend on estate size.

Pricing the zero against the taxing states. The same $5,000,000 estate would compute to $292,000 in Massachusetts, $260,000 in Minnesota and $0 in Maryland, whose exemption sits at exactly $5,000,000. At the $15,000,000 scenario the figures become roughly $1,767,200, $1,659,000 and $1,600,000 against Mississippi's $0.00. Mississippi's neighbours are no different: Alabama, Louisiana, Arkansas and Tennessee all repealed their estate taxes, so the nearest state-level estate tax to a Mississippi decedent is a long way off.

The deductions input has no effect on the headline. Entering $1,000,000 of deductions against a $5,000,000 gross estate returns $0.00 of Mississippi tax, unchanged. It does move the net-value-distributed output down to $4,000,000.00, because the engine subtracts deductions from gross before reporting what passes on. In a state with no estate tax the deduction field therefore changes what the page shows heirs receiving and cannot change what the state collects, which is $0.00 at every input combination.

Where the real exposure sits, and why this page cannot show it. The threshold a Mississippi family actually tracks is federal, and this calculator performs no federal computation: there is no federal exemption stored, no Form 706 logic, and no portability handling anywhere in the code path. The one state-level exposure that can still arise is out-of-state real property, because an estate tax state generally reaches property sited within its borders regardless of the decedent's domicile. A Mississippi decedent owning a Massachusetts second home has a Massachusetts filing question that this page's $0.00 does not answer, and there is no input here in which to record where the assets are.

• Federal generation-skipping transfer (GST) tax under IRC Chapter 13.
• Ancillary probate requirements for real property situated in other jurisdictions.
• Complex liquidity discounts for minority non-voting family business entities.
• State-specific inheritance taxes levied directly on beneficiaries (e.g. PA, NJ, MD, KY, NE).

• Assuming State Exemption Matches Federal: Forgetting that states like Oregon ($1.0M) and Massachusetts ($2.0M) tax estates far below the federal threshold.
• The "Cliff" Effect in Specific States: Failing to recognize that states like New York eliminate the exemption entirely if the estate exceeds 105% of the threshold.
• Out-of-State Real Property Exposure: Holding real estate in states with active estate taxes exposes non-resident estates to proportional state estate taxes.
• Failing to Fund Revocable Living Trusts: Assets held outside trust structures are subjected to public probate proceedings and statutory executor fees.

• Mississippi Department of Revenue: General state tax administration; Mississippi levies no state-level estate tax, so only the federal estate tax applies. dor.ms.gov
