How to Avoid Capital Gains Tax When Selling an Inherited Home in Louisiana

If you inherited a home in Louisiana and are planning to sell it, the capital gains tax may be zero — but only if you follow three specific steps in the right order. Louisiana's community property laws provide a double step-up in basis that does not exist in common-law states: when one spouse dies, both halves of community property receive a full step-up to fair market value at the date of death. A home purchased for $180,000 that is worth $380,000 when a spouse dies gets a new basis of $380,000 for the entire property. Sell it for $380,000 and the capital gains tax is zero. But miss the required documentation steps and the IRS may only recognize a step-up on the deceased's half — costing you tens of thousands in avoidable taxes.

How the Louisiana Double Step-Up Works

In every common-law state, when one spouse dies, only the deceased's half of jointly held property receives a step-up in basis. The surviving spouse's half keeps its original basis.

Common-law state example:

• Home purchased for $200,000 (each spouse's basis: $100,000)
• Fair market value at date of death: $400,000
• Deceased's half steps up to $200,000
• Surviving spouse's half stays at $100,000
• New combined basis: $300,000
• Capital gains if sold for $400,000: $100,000 taxable

Louisiana community property example:

• Same home, same numbers
• Both halves step up to $200,000 each
• New combined basis: $400,000
• Capital gains if sold for $400,000: $0 taxable

This is IRC Section 1014(b)(6) — the federal tax code specifically provides for this treatment when property is community property under state law. Louisiana is one of only nine community property states, and the double step-up applies to all community property, not just real estate.

The Three Steps You Cannot Skip

The double step-up is a tax benefit, not an automatic adjustment. You must actively establish the new basis through three documented steps. Skip any one and you risk the IRS challenging the stepped-up basis on the surviving spouse's half.

Step 1: Get a Date-of-Death Appraisal

Hire a licensed appraiser to establish the fair market value of the property as of the date of death. This is not the parish tax assessor's value. It is not a Zillow estimate. It is a formal appraisal that will withstand IRS scrutiny if the return is ever audited.

Timing matters. Order the appraisal as soon as possible after the death. The appraiser can work retroactively, but the further the appraisal date is from the death date, the more vulnerable the valuation becomes to challenge. Ideally, the appraisal should be completed within 90 days.

Cost: $300 to $600 for a standard residential appraisal in Louisiana. This is the cheapest step in the entire process and the most valuable — it establishes the basis that eliminates the capital gains tax.

Step 2: Record a Judgment of Possession

In Louisiana, a Judgment of Possession is the court order that formally transfers ownership of the deceased's property to the heirs. It must be recorded in the parish conveyance records where the property is located. Without it, no title company will insure a sale, and the basis step-up lacks the legal documentation to support it.

For estates under $125,000, the Small Succession Affidavit (expanded by Act 90 of 2024) can serve a similar function. For larger estates, a formal succession proceeding is required.

The critical point: The Judgment of Possession must be recorded before the property sale closes. If you sell first and try to record afterwards, the chain of title is broken and the title company will not close the transaction.

Step 3: Sell at or Near the Stepped-Up Basis

The step-up resets the basis to fair market value at the date of death. If you sell the property quickly — within a few months of death — the sale price and the stepped-up basis will be nearly identical, producing little or no capital gain. The longer you wait to sell, the more the property may appreciate above the stepped-up basis, creating a taxable gain on the post-death appreciation.

There is no mandatory holding period. You can sell the day after the Judgment of Possession is recorded. The step-up applies regardless of how quickly you sell.

What Can Go Wrong

Mistake 1: Selling Without a Judgment of Possession

The most common and most expensive mistake. Without the recorded Judgment of Possession, the title company will not close the sale. Some sellers attempt to work around this with a quitclaim deed or an informal family agreement. These do not establish the legal basis for the step-up and create title defects that can haunt the property for decades.

Mistake 2: Using the Tax Assessor's Value Instead of a Formal Appraisal

The Louisiana parish tax assessor's value is typically 10% of fair market value for homestead-exempt property. It is not an appraisal and the IRS will not accept it as a basis determination. Without a formal date-of-death appraisal, you have no defensible basis if the IRS questions the capital gains calculation.

Mistake 3: Assuming Separate Property Gets the Double Step-Up

Only community property qualifies for the double step-up. If the home was the deceased's separate property — inherited by the deceased individually, purchased before the marriage, or acquired with separate funds — only the deceased's interest receives a step-up. The classification of the property matters enormously, and an incorrect assumption can create an unexpected five-figure tax bill.

Mistake 4: Waiting Too Long to Sell

The step-up freezes the basis at the date-of-death value. Every dollar of appreciation after that date is a taxable capital gain. In a market where Louisiana home values are rising 3% to 5% annually, waiting two years to sell a $400,000 home can create $24,000 to $40,000 in post-death appreciation — all of it taxable. If you plan to sell, do it while the basis and the market value are close.

Mistake 5: Forgetting Federal and State Capital Gains Rates

Even when the double step-up eliminates most or all of the gain, any remaining gain is taxed at both federal and state rates. Federal long-term capital gains rates are 0%, 15%, or 20% depending on income. Louisiana taxes capital gains as ordinary income at the flat 3% state rate. For a $50,000 gain that should have been zero, the combined tax bill can exceed $9,000.

Who This Is For

• Surviving spouses in Louisiana planning to sell the family home and wanting to understand how the double step-up eliminates capital gains tax
• Heirs who inherited a parent's community property home and need to know the documentation steps before listing it for sale
• Out-of-state adult children who need to sell their deceased parent's Louisiana home and want to capture the full basis step-up before the property appreciates further
• Executors managing an estate where the primary asset is the family home and the beneficiaries want to liquidate

Who This Is NOT For

• Heirs who inherited separate property (not community property) — you still get a single step-up on the deceased's interest, but the double step-up does not apply
• Surviving spouses who plan to keep the home indefinitely — the step-up benefit is captured automatically and only matters when you eventually sell
• Estates with property in multiple states — you may need ancillary proceedings in other jurisdictions, and community property treatment depends on where the couple was domiciled

The Numbers That Matter

To put the double step-up in perspective:

A couple buys a home in Baton Rouge in 2005 for $220,000. One spouse dies in 2026 when the home is worth $420,000. The appreciation is $200,000.

Without the double step-up (common-law state treatment): Only the deceased's half steps up. New basis: $310,000 ($110,000 original for surviving spouse + $210,000 stepped-up for deceased's half). Capital gains on a $420,000 sale: $110,000. Federal tax at 15%: $16,500. Louisiana tax at 3%: $3,300. Total: $19,800.

With the double step-up (Louisiana community property): Both halves step up. New basis: $420,000. Capital gains on a $420,000 sale: $0. Total tax: $0.

The difference is $19,800 in taxes — eliminated by a $300 appraisal and a Judgment of Possession.

Frequently Asked Questions

Does the double step-up apply to all property, or just the family home?

The double step-up applies to all community property, not just real estate. Investment accounts, vehicles, business interests, and other assets acquired during the marriage with community funds all qualify. The home is the most common asset where the benefit is significant because of the large appreciation involved.

What if the home was purchased before the marriage?

Property purchased before the marriage is generally separate property. Only the deceased's interest receives a step-up. However, if community funds were used to pay the mortgage during the marriage, a portion of the home's value may be classified as community property. The classification can be complex and may require legal analysis.

Can I get the double step-up if there is no will?

Yes. The double step-up in basis is a federal tax provision (IRC Section 1014(b)(6)) that applies to community property regardless of whether the deceased had a will. The basis step-up is determined by property classification, not by testamentary disposition.

How long do I have to sell the home to get the tax benefit?

There is no deadline. The step-up is permanent — the new basis is locked in at the date-of-death value forever. However, any appreciation after the date of death is a taxable gain. The closer the sale is to the date of death, the smaller the post-death appreciation and the lower the tax bill.

Do I need to file Form 706 to get the double step-up?

No. The step-up in basis under IRC Section 1014 applies automatically to inherited property. Form 706 (the federal estate tax return) is required only for estates exceeding $13.61 million, or when the surviving spouse wants to elect portability to capture the deceased's unused estate tax exemption. The step-up and Form 706 are independent provisions.

What if I rent out the inherited home instead of selling it?

The stepped-up basis still applies. It becomes your new depreciable basis for the rental property. You can depreciate the building portion of the stepped-up value over 27.5 years for residential rental property, which reduces your taxable rental income. If you sell later, your gain is calculated from the stepped-up basis minus any depreciation taken, not from the original purchase price.
