Louisiana Capital Gains Tax, Explained
A 2024 reform swapped graduated brackets for one flat 3% rate and quietly repealed the old Louisiana-business-sale deduction. Here's what changed and what the math looks like now.

Quick Answer
Louisiana taxes capital gains as ordinary income at a flat 3% rate, the result of a 2024 tax reform that replaced the old graduated brackets. A $150,000 gain costs $4,500 in Louisiana tax, regardless of how long you held the asset. There used to be a separate deduction for selling a Louisiana business, but that deduction was repealed as part of the same reform and no longer applies to sales in 2025 or later. Stack the federal side (0/15/20% plus the 3.8% NIIT for higher earners) on top to get your real number. Run your numbers in our capital gains tax calculator, entering 3% in the state field.
The 2024 Reform: From Graduated Brackets to One Flat 3%
Through 2024, Louisiana taxed income on a graduated schedule that topped out at 4.25%. Governor Landry's tax reform package changed that. Voters approved a constitutional amendment in November 2024, and the legislature's companion act repealed the graduated brackets entirely, replacing them with a single flat 3% rate on Louisiana taxable income for taxable periods beginning on or after January 1, 2025. There's no separate capital gains rate. Every dollar of gain, whether it's stock, crypto, a rental in Baton Rouge, or a business interest, is ordinary income to the state, taxed at that one flat rate.
Worked example: sell for a $150,000 gain and Louisiana's cut is $4,500, 3%, full stop. No brackets to climb, no separate rate for short-term versus long-term. Compare that to the old top bracket of 4.25%, and most Louisiana sellers are paying less state tax on a gain today than they would have in 2024, even without the business-sale deduction that used to exist (more on that below).
| Your federal LTCG bracket | Louisiana rate | Combined federal + LA |
|---|---|---|
| 0% federal bracket | 3% | 3%, Louisiana still collects |
| 15% federal bracket | 3% | 18% (21.8% with NIIT) |
| 20% federal bracket + NIIT | 3% | 26.8% all-in |
Notice the first row: a long-term gain the IRS taxes at 0% is still Louisiana income. Because Louisiana's return starts from your federal numbers, the same gain that owes nothing to the IRS still owes 3% to the state.
A simpler system, not a bigger break
The flat 3% rate makes Louisiana one of the more legible state tax systems in the country to plan around. But don't confuse simplicity with a windfall: the same 2024 reform that lowered the top rate also eliminated the old business-sale deduction, so the net effect on a large gain depends heavily on what kind of gain you're realizing.
The Old Louisiana Business-Sale Deduction Is Gone
If you researched Louisiana capital gains tax before the 2024 reform, you may remember a state-specific break under R.S. 47:293(9)(a)(xvii): a deduction for the net capital gain on selling an equity interest in, or substantially all the assets of, a non-publicly traded business commercially domiciled in Louisiana. It required both you and the business to have been in place for at least five years, and the deduction percentage climbed the longer the business had been domiciled in the state, from 50% at the five-year mark up to a full 100% exclusion at 30 years or more.
That statute no longer exists. As part of the same 2024 tax reform package that created the flat 3% rate, the legislature repealed R.S. 47:293(9)(a)(xvii) outright, effective for sales and exchanges on or after January 1, 2025. If you're planning the sale of a Louisiana business today, there is no state-level exclusion waiting for you at the five-year mark. The gain is simply Louisiana ordinary income at 3%, same as everything else.
| Feature | Before 2025 (repealed) | 2025 and after (current law) |
|---|---|---|
| State rate on capital gains | Graduated, up to 4.25% | Flat 3% |
| Louisiana business-sale deduction | Up to 100% exclusion after 30 years domiciled in LA | Repealed, not available |
| Minimum holding period for any state break | 5 years (business-sale deduction only) | None, flat rate applies from day one |
A narrow transition rule, not a planning strategy
A limited exception preserved the old deduction only for sales under a purchase agreement that was fully executed, with every contractual condition already satisfied, before January 1, 2025, even if the closing happened later. That window is closed. If you're structuring a business sale now, build the model around the flat 3% rate with no deduction, not around the old statute.
The takeaway for anyone selling a business built and held in Louisiana: the state tax planning conversation has shifted entirely to the federal side, entity structure, and sale timing, since the old five-year Louisiana carrot is off the table.
Stacking the Federal Layer on Top
Louisiana's flat 3% is only the state layer. The federal government still taxes the gain under its own rules: 0%, 15%, or 20% for long-term gains depending on your bracket, ordinary federal rates up to 37% for short-term gains, and the 3.8% net investment income tax layered on above $200,000 MAGI (single) or $250,000 (married filing jointly).
Because Louisiana's return builds from your federal adjusted gross income, the planning moves that shrink your federal number do double duty automatically:
- Loss harvesting: losses that offset gains federally shrink the Louisiana number in the same motion.
- Gain timing: a gain pushed into a lower-income year saves at both layers at once.
- 1031 exchanges: gain deferred federally generally stays out of Louisiana income too, with no separate state tracking form.
- Installment sales: spreading a gain across years spreads the Louisiana bill along with the federal one.
Model both layers together, not the state rate in isolation
A flat 3% state rate feels small next to the federal number, which is exactly why it's easy to overlook. On a seven-figure gain, 3% is still tens of thousands of dollars. Before finalizing a large sale, run the combined federal-plus-Louisiana number rather than treating the state side as an afterthought.
Selling a Louisiana Rental: Recapture Is Just More Income
On the federal side, a rental sale splits into layers: the depreciation you claimed comes back as recapture at up to 25%, the remaining gain gets long-term rates, and the NIIT can ride on top. Louisiana flattens the whole stack, recapture and appreciation alike, into ordinary income at the flat 3% rate.
Worked example: you sell a New Orleans-area rental for a $200,000 total gain, of which $60,000 is depreciation recapture, and you're in the 15% federal bracket. Federal: $60,000 x 25% = $15,000, plus $140,000 x 15% = $21,000, for $36,000. Louisiana: $200,000 x 3% = $6,000, no separate recapture rate, no separate schedule. Combined: about $42,000 before any NIIT.
Two notes follow from that math. First, because Louisiana's bill scales with the total gain at a low flat rate, the state side of recapture is mild, the federal 25% layer is where recapture actually hurts, so sizing your accumulated depreciation before you list is the useful homework. Second, if a 1031 exchange is on the table, the deferral generally carries the Louisiana tax along with the federal one, since Louisiana starts from federal AGI.
Selling Oil-and-Gas Interests and New Orleans Real Estate
Two kinds of Louisiana sellers ask about this page more than most: owners of working or royalty interests in oil-and-gas properties, and owners of investment or short-term-rental property in and around New Orleans. Both face the same state math now, a flat 3% on the gain, with the interesting complexity sitting entirely on the federal side.
Selling a working interest or royalty interest in oil-and-gas property can trigger recapture of depletion deductions claimed over the years, taxed federally as ordinary income, similar in spirit to depreciation recapture on a rental. Louisiana's role is unchanged either way: the entire gain, whatever its federal character, is ordinary Louisiana income at the flat 3% rate. There's no special state treatment for mineral interests and no separate Louisiana schedule for the industry.
For a New Orleans-area rental or short-term rental sold after using the STR strategy to accelerate depreciation, the exit math works the same way it does for any rental: the depreciation that sheltered income during ownership generally comes back as recapture at sale, and Louisiana taxes that recapture at 3% along with the rest of the gain.
A six-figure gain usually means an estimated-payment problem too
Whether the gain comes from a mineral interest or a French Quarter rental, a large sale with no withholding usually means quarterly estimated tax payments, federal and Louisiana both, come due the same quarter as the sale, not the following spring. Model the cash-flow timing before the closing date, not after.
