Louisiana enacted a landmark flat-tax reform in 2024 (HB 10, signed by Governor Landry, effective January 1, 2025): a single 3% flat rate on all income, replacing the old 1.85-4.25% 3-bracket progressive system. The reform also introduced a new standard deduction for single filers ($12,500 in 2025; $12,875 for 2026) and eliminated Louisiana's former federal income tax deductibility — which had made the old system uniquely complex. At $100K income, effective state rate is just 2.61% ($2,614 tax) — the lowest in the Deep South.
Why the reform happened: Louisiana cut taxes aggressively to compete with no-income-tax neighbors (Texas, Tennessee, Florida) and to attract businesses and high earners. The old progressive system with federal tax deductibility was one of the most complex in the nation. The new 3% flat with a $12,875 (2026) SD is transparent and predictable. Governor Landry called it the most significant tax reform in state history.
How it compares regionally now:
The high sales tax tradeoff: Louisiana still compensates with high sales taxes: a 5% state rate (since January 1, 2025) plus parish and local taxes. Combined city rates quoted elsewhere on this page predate the 2025 state increase and are not re-verified. At $50K spending, sales tax costs $4,725-4,975/year.

Here's what Louisiana residents actually pay at different income levels (2026, single filer, standard deduction):
| Annual Income | Federal Tax | State Tax | Total Tax | Take-Home Pay | Effective Rate |
|---|---|---|---|---|---|
| $50,000 | $3,820 | $1,114 | $4,934 | $45,066 | 9.9% |
| $75,000 | $7,670 | $1,864 | $9,534 | $65,466 | 12.7% |
| $100,000 | $13,170 | $2,614 | $15,784 | $84,216 | 15.8% |
| $150,000 | $24,734 | $4,114 | $28,848 | $121,152 | 19.2% |
| $250,000 | $51,304 | $7,114 | $58,418 | $191,582 | 23.4% |
Note: Includes federal and state income tax only. Does not include FICA (Social Security/Medicare), which adds 7.65% for employees.
Key takeaway: At $100K, Louisiana takes $2,614 in state tax alone.

Tax considerations if moving here:
| State | Tax Rate | Tax on $100K Income | Difference from Louisiana |
|---|---|---|---|
| Louisiana | 3% flat | $2,614 | Baseline |
| Texas | 0% | $0 | -$2,614 (less tax) |
| Mississippi | 4% flat | $3,268 | +$654 (more tax) |
| Alabama | 2-5% | $4,102 | +$1,488 (more tax) |
| Arkansas | 0-3.7% | $3,490 | +$876 (more tax) |
Key insight: Louisiana's new 3% flat tax reform makes it the lowest income-tax state in the Deep South with any income tax at all. At $100K income, LA ($2,614) now beats MS ($3,268), AL ($4,102), and AR ($3,490). Only TX/TN (0%) are cheaper. However, LA's income tax savings are partially offset by the highest-in-nation sales tax (9.95% Baton Rouge vs 8.25% Houston).
Total tax burden comparison at $100K income + median home:
Result: Now that Louisiana's real post-reform income tax figure is used, Louisiana's total tax burden (9.0%) is actually LOWER than both Texas (9.9%) and Alabama (10.2%) — not virtually identical to Texas as this page previously claimed. Louisiana's much lower property tax (0.55% vs Texas's 1.6%) more than offsets its higher sales tax, and its income tax is now genuinely low too. Only Mississippi (7.8%) still beats Louisiana on total burden among these four. Choose based on: culture (LA wins - New Orleans), job market (TX wins - Houston/Dallas), education (TX wins - better schools), hurricanes (both have risk). At $200K income, Texas's income-tax-free advantage grows large enough to overtake Louisiana on income tax alone ($5,614 LA vs $0 TX), but Louisiana's much lower property tax still narrows the gap to about $1,257/year in Texas's favor overall — not the larger margin this page previously stated.
The sales tax shock - hidden cost of Louisiana:
The Texas question - Houston vs New Orleans lifestyle choice:
Best use case for Louisiana:
After Louisiana's 3% flat reform, the comparison with Texas changed significantly. At $100K income: LA $2,614 income tax vs TX $0. Louisiana has 0.55% property tax (vs TX 1.6%) and cheaper housing ($255K Baton Rouge vs $360K Houston) = $1,403/year LA property tax vs $5,760 TX. The $2,614 LA income tax is more than offset by $4,357 lower property tax — Louisiana's total tax burden at $100K is now LOWER than Texas for homeowners. TX's brutal property tax ($5,760/year) far exceeds LA's income tax ($2,614). Then LA's higher sales tax (9.95% vs 8.25%) adds back ~$850. Net for homeowners: LA wins on total burden, by about $893/year. For high earners $200K+: TX still wins on income tax savings. For retirees (SS exempt in LA + low property tax on paid-off home): LA wins clearly.
No Social Security tax - Louisiana fully exempts Social Security income at all ages and income levels. Military and federal retirement pay also fully exempt. Public pensions: LA state employee pensions and teacher retirement (TRSL) and other listed public systems are exempt. Other pensions/401k/IRA: Taxed at the flat 3% rate, but age 65+ can exempt up to $12,000 of retirement income (2025 return). Example: Age 66 with $35K SS + $45K private pension = $80K total. SS fully exempt, pension taxed at the flat 3% rate after the $12,000 retirement exemption and the $12,875 standard deduction ($45,000 - $12,000 - $12,875 = $20,125 taxable) = $604 LA tax (0.76% effective on the $80K total). Compare to Texas $0 (no income tax) but TX property tax on home is $4,000-6,000/year vs LA $1,500-2,000. For retirees with paid-off home, Louisiana is competitive - low income tax + low property tax + warm climate + culture. But consider: healthcare quality (LA ranks 46th), hurricane risk, infrastructure decay.
Louisiana has highest average sales tax in the nation (5% state rate since January 1, 2025, plus local taxes) to compensate for low income tax and volatile oil/gas revenue. Structure is regressive - sales tax hits lower-income residents hardest (they spend higher % of income on taxable goods). At $100K income with $50K annual spending: pay $2,614 income tax (2.61%) + $4,975 sales tax (9.95% Baton Rouge) = $7,589 total (7.6%). At $50K income with $35K spending: pay $1,114 income tax (2.23%) + $3,483 sales tax = $4,597 total (9.2%). Lower earners still pay a HIGHER effective rate due to sales tax burden, even under the reformed system. Why? Oil/gas severance taxes ($1.2B/year) subsidize income tax, but when oil prices crash (2015-2016), state raised sales tax to fill budget holes. Sales tax is politically easier to raise than income tax.
If you can earn $80-120K at Louisiana refineries/petrochemical plants (Exxon Baton Rouge, Motiva/Shell Convent, Sasol Lake Charles, Valero St. Charles), Louisiana is competitive vs Texas due to lower housing costs and similar industry wages. At $100K oil/gas job: LA total tax 9.0% ($2,614 income + $1,403 property on $255K Baton Rouge home + $4,975 sales) vs TX 9.9% — Louisiana is actually somewhat lower now, not merely similar. But LA housing $255K vs Houston $360K (save $105K), and New Orleans culture is unique. Tradeoffs: Louisiana has worse schools (50th), crumbling infrastructure, hurricane risk, and volatile economy (when oil crashes, layoffs happen - 2015-2016 LA lost 20K oil/gas jobs). Texas oil/gas jobs are more stable (Houston is energy capital, diverse employers). Best for: mid-career oil/gas professionals prioritizing culture/lifestyle over career growth. Avoid if: you have school-age kids (schools are terrible) or risk-averse (hurricane/flood insurance $3K-5K/year coastal parishes).
Louisiana has a 9.0% total state/local tax burden at $100K income, held up more than it used to be by the nation's highest sales tax now that the income-tax reform is properly reflected. At $100K with $255K Baton Rouge home + $50K annual spending: $2,614 income (2.61% - lowest in Deep South) + $1,403 property (0.55%) + $4,975 sales (9.95% Baton Rouge - highest in US!) = $8,992 total (9.0% of income). This now beats both Texas (9.9%) and Alabama (10.2%) and easily beats Georgia (13.2%), but still loses to Mississippi (7.8%). Key insight: Louisiana's "low income tax" claim is now genuinely true even on total burden — the sales tax is still a real cost, but no longer erases the income-tax advantage. The 9.95% Baton Rouge/9.45% New Orleans sales tax crushes consumption. At $50K spending, you pay $4,725-4,975/year sales tax alone. Structure is regressive - lower earners pay higher effective rate because they spend higher % of income. Louisiana taxes consumption instead of wealth, which favors high earners (they save more, spend less %) over middle class.

How we calculate: Louisiana uses a flat 3% tax rate (2025 reform, HB 10) applied to Louisiana taxable income (federal AGI minus Louisiana's $12,875 standard deduction for single filers in 2026, or itemized deductions if greater). Our calculator applies the marginal rates to each bracket and sums the total tax. We add federal income tax using official 2026 IRS brackets. Effective tax rates are calculated by dividing total tax by gross income. For comparison purposes, we show neighboring states' tax calculations at the same income levels using their official 2026 tax brackets and rates.
Data sources:
Verification: Louisiana's flat 3% tax rate verified against Louisiana Revised Statutes §47:32 (Income Tax Rates) and LA Department of Revenue 2026 tax guidance published January 2026. Sales tax rates verified against Louisiana Sales Tax Commission rate database (updated January 2026) and Louisiana Department of Revenue sales tax report. Property tax rates verified against Louisiana Tax Commission 2025 Property Tax Report (0.62% statewide average). Federal tax bracket accuracy verified against IRS Revenue Procedure 2025-58 (2026 inflation adjustments). Migration data sourced from IRS Statistics of Income (SOI) Tax Stats via Census Bureau. Oil/gas production and severance tax data verified against Louisiana Department of Natural Resources 2025 annual report. Housing cost data from Zillow Home Value Index (January 2026).
Limitations: Assumes single filer with W-2 income only, standard deduction (not itemized), Louisiana full-year residency. Does not include: LA-specific deductions (limited availability compared to other states), federal tax credits (EITC, child tax credit - LA has high EITC usage due to poverty), part-year or nonresident calculations, self-employment tax, sales tax variations by parish (5% state rate plus local taxes), property tax variations by parish (ranges 0.3-1.2% effective rate, higher in New Orleans/Jefferson Parish, lower in rural north Louisiana), hurricane/flood insurance costs ($2,000-5,000/year in coastal parishes), coastal restoration levies (some parishes have special property tax assessments for levee maintenance). Retirement income calculations simplified - Social Security always exempt, federal/military and LA state/teacher retirement exempt, other retirement income taxed at the flat 3% rate with up to $12,000 exempt at age 65+ (2025 return).
For complex situations: Consult a licensed Louisiana CPA or tax attorney, especially for: part-year residency (LA taxes income earned while LA resident based on domicile test), multi-state income allocation (border region workers in Houston, Baton Rouge-Mississippi, Shreveport-Texas metros), retirement income (age 65+ retirement exemption, military retirement exemption, Social Security exemption verification), oil/gas royalties (common in south Louisiana, special depletion deductions), rental property income (common in New Orleans - Airbnb/VRBO short-term rentals, depreciation rules), business income (LA C-corps taxed 4-8% graduated, S-corps/partnerships taxed at individual progressive rates), coastal property (hurricane insurance requirements, flood insurance mandatory in FEMA zones, levee assessments).
