Mississippi does not have an inheritance tax. The state also imposes no estate tax and no gift tax, so receiving money or property from someone who has died creates no state tax bill in Mississippi, regardless of how you were related to the person or what you inherited. Federal estate tax can still apply to very large estates, and a few separate situations, like selling inherited property or inheriting real estate located in another state, can create tax obligations worth knowing about.
Why Mississippi Doesn’t Tax Inheritances
Mississippi eliminated its estate tax for all deaths occurring on or after January 1, 2005. The old tax was tied to a federal credit that let estates offset what they paid to Mississippi against their federal estate tax. When the federal government replaced that credit with a deduction, the Mississippi tax stopped producing revenue, and the state stopped requiring estate tax returns.1Mississippi Department of Revenue.

The Mississippi Department of Revenue also confirms the state has no gift tax.1Mississippi Department of Revenue. Estate Cash, real estate, vehicles, retirement accounts, investments, personal belongings, life insurance proceeds: the state doesn’t tax any of it when it changes hands at death. Children, siblings, spouses, friends, and unrelated beneficiaries all receive the same treatment.
The Federal Estate Tax Still Applies to Large Estates
The federal government taxes estates, but only very large ones. For someone who dies in 2026, federal estate tax applies only to the portion of an estate above $15,000,000. A married couple can effectively shield up to $30,000,000 by combining both exemptions.2Internal Revenue Service. Frequently Asked Questions on Estate Taxes
Amounts above the threshold are taxed on a graduated scale that tops out at 40%.3Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax The estate itself pays this tax before assets are distributed, so individual heirs do not receive a bill from the IRS for the estate tax.
The executor files IRS Form 706 if the gross estate plus any adjusted lifetime taxable gifts meets or exceeds $15,000,000.2Internal Revenue Service. Frequently Asked Questions on Estate Taxes The return is due nine months after death. Filing IRS Form 4768 before that deadline grants an automatic six-month extension.4eCFR. 26 CFR 20.6081-1 – Extension of Time for Filing the Return Most Mississippi estates fall well below the threshold and never touch Form 706 at all.
Selling Inherited Property and the Stepped-Up Basis
The most common tax question heirs actually run into isn’t about the inheritance itself. It’s about what happens when they sell what they inherited.
Inherited property gets a stepped-up basis. Your tax basis, the number used to calculate gain or loss when you sell, resets to the fair market value on the date the previous owner died, rather than whatever they originally paid.5Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
Say your parent bought a house for $80,000 and it was worth $350,000 the day they died. Your basis is $350,000. Sell it for $355,000 shortly after, and you owe capital gains tax only on the $5,000 difference. The $270,000 of appreciation that built up during your parent’s lifetime is never taxed to you.
Sales of inherited property are reported on Schedule D of your federal return. If the executor filed an estate tax return and reported a specific value for the property, your basis must be consistent with that reported value, or you can face an accuracy-related penalty.6Internal Revenue Service. Gifts and Inheritances
Inheriting Property Located in Another State
Mississippi’s rules protect you only from Mississippi tax. A few states still charge inheritance tax, and that tax generally follows the property, not the heir.
Five states currently impose inheritance taxes: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Rates range from 0% for close relatives, who are often fully exempt, up to 16% for distant relatives and unrelated beneficiaries. Real estate and tangible personal property are taxed by the state where they physically sit. If you live in Mississippi and inherit a house in one of those states, that state can bill you based on the property’s value and your relationship to the deceased. Intangible property like stocks and bank accounts is generally taxed based on the deceased person’s state of residence rather than the heir’s.
Any state estate or inheritance tax paid can be claimed as a deduction on the federal estate tax return if one is filed, reducing the federal bill. Multi-state situations are complicated enough to justify a professional familiar with both jurisdictions.
Mississippi Income Tax Returns After a Death
No inheritance tax doesn’t mean no state filings. Two separate income tax returns often need to be filed after a Mississippi resident dies.
The first is the deceased person’s final income tax return, covering income earned from January 1 through the date of death. For 2026, Mississippi taxes income above $10,000 at a flat 4%, with the first $10,000 exempt.7Mississippi Department of Revenue. General Information The executor or administrator signs and files this return, reporting all wages, interest, dividends, and other taxable income earned before death.8Justia Law. Mississippi Code 27-7-15 A final federal Form 1040 covers the same period.
Fiduciary Returns for Income the Estate Earns
Income the estate’s assets earn after the date of death, such as rent from a property, dividends from stocks, or bank interest, belongs to the estate as a legal entity and gets reported separately.
At the state level, the executor files Mississippi Form 81-110, the Fiduciary Income Tax Return for Estates and Trusts.9Mississippi Department of Revenue. Fiduciary Income Tax Return Instructions At the federal level, IRS Form 1041 is required if the estate earns gross income of $600 or more during the tax year, or if any beneficiary is a nonresident alien.10Internal Revenue Service. Instructions for Form 1041 These fiduciary returns cover only what the assets produce while the estate holds them; they aren’t a tax on the inheritance itself.
Small Estate Affidavit for Estates Under $50,000
Mississippi lets beneficiaries skip full probate when the estate is small. If the deceased person’s personal property totals $50,000 or less, a small estate affidavit can be used to collect assets directly from a bank, employer, or anyone else holding the property.11Justia Law. Mississippi Code 91-7-322 – Payment of Indebtedness or Delivery of Personal Property of Decedent to Successors
Three conditions have to be met:
- At least 30 days have passed since the date of death.
- No one has applied for or been appointed as personal representative of the estate.
- The personal property in the estate totals $50,000 or less.
The affidavit goes directly to the institution holding the asset. Once the holder releases property in good faith based on the affidavit, they’re protected from liability. Real estate can’t be transferred through this process and still requires probate or another legal instrument.
Refusing an Inheritance
A beneficiary who doesn’t want an inheritance, for creditor protection, tax planning, or personal reasons, can formally refuse it through a legal disclaimer. Mississippi law requires the disclaimer to be filed within nine months of the date of death for a present interest in property passing under a will or through intestacy.12Justia Law. Mississippi Code 89-21-5 – Time of Disclaimer
The disclaimer is filed in the chancery court of the county where the estate is being administered, with a copy delivered to the executor by certified mail or in person. The disclaimed property then passes as if the disclaiming beneficiary had died before the deceased, moving to the next person in line under the will or state intestacy rules. Once you’ve accepted any benefit from the inherited property, you can no longer disclaim it.
