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

Louisiana charges nothing at death, having repealed its inheritance tax in 2004; the state's distinctive forced-heirship rules govern who inherits, not what the state collects. Louisiana is among the 38 states levying no separate state estate tax today.

Nor does Louisiana levy a separate inheritance tax on beneficiaries, so heirs here face no state-level death tax of either kind, regardless of how the estate is structured or how many beneficiaries ultimately share in it.

The only number that matters for a Louisiana estate, then, is the federal exemption (currently above $15,000,000 per individual for 2026), since nothing at the state level reduces what beneficiaries ultimately receive.

That simplicity is one reason retirees and high-net-worth households have historically relocated to no-tax states like Louisiana, though residency for tax purposes turns on where someone is actually domiciled, not just where they own a vacation home.

Louisiana is a Deep South, Gulf Coast state, but that has no bearing on the calculation here: a Louisiana resident's estate is unaffected by changes to other states' exemption thresholds, since only Louisiana and federal law govern property held within it.

There is no Louisiana 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 Louisiana 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 Louisiana 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 Louisiana's estate tax status. Louisiana 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 Louisiana 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 Louisiana 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 Louisiana'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.

The sweep, in full. Twelve rows scale the net estate from $833,333.33 to $10,000,000.00 and every one returns $0.00 of Louisiana estate tax. So does $50,000,000. calculateStateEstateTax reads hasEstateTax: false for Louisiana from the 2026 table and returns a zero result without evaluating a single bracket, so there is no threshold, no cliff and no phase-out at any estate value.

Two zero outputs that mean "not applicable", not "nil allowance". The exemption threshold reads $0.00 and the taxable estate above exemption reads $0.00. Both are defaults returned when no schedule is loaded. Compare the Maine page in this same family, where the exemption field reads $7,160,000 because a schedule exists: the difference between those two outputs is the presence or absence of a statute, not the size of an allowance.

The deductions field, and the comparison that makes it clear. Enter $1,000,000 of deductions against the $5,000,000 default and the net estate distributed drops to $4,000,000.00 with the tax unchanged at $0.00. The same $1,000,000 of deductions against a $10,000,000 Maine estate reduces the state tax from $227,200.00 to $147,200.00, a saving of $80,000.00. In Louisiana the identical entry is worth nothing, which is the practical content of "no state estate tax".

Marginal cost of the next dollar of estate. Zero, at every value. No Louisiana consideration argues for accelerating a gift, discounting a closely held valuation, or funding an insurance trust to create liquidity for a state bill, because there is no state bill.

What sits outside the zero. Louisiana appears in neither the engine's estate-tax schedule nor its inheritance-tax table, which holds only Pennsylvania, Nebraska, Maryland, Kentucky and New Jersey, so no death tax of either kind is modelled for this state. The federal estate tax is not computed here at any estate value: the $5,000,000.00 shown as distributed is before federal tax, and the engine carries no Form 706 logic, no portability election, no lifetime gift add-back and no generation-skipping transfer tax. Louisiana's forced heirship rules, which constrain who receives the estate rather than what it is taxed, are likewise nowhere in this calculation.

• 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.

• Louisiana Department of Revenue: General state tax administration; Louisiana levies no state-level estate tax, so only the federal estate tax applies. revenue.louisiana.gov
