Louisiana enacted landmark tax reform in late 2024: a flat 3% individual income tax rate replaced the old 1.85%–6% graduated structure, effective January 1, 2025. Louisiana retains its unique federal income tax deduction (you can deduct your federal taxes paid from Louisiana taxable income) and does not tax Social Security income. Louisiana has among the lowest property taxes in the US (~0.51% effective rate). Moving to Texas (no income tax) from Louisiana saves the 3% rate on all income — a relatively small amount for most residents.

Key Facts
Louisiana Income Tax Rate (2025)
Flat 3% on all Louisiana taxable income — down from the graduated 1.85%–6% structure that applied through 2024. Louisiana's corporate income tax was also reduced. The 2024 reform (Act 1 of the First Extraordinary Session of 2024) represents one of the largest rate cuts in Louisiana history.
Federal Income Tax Deduction
Louisiana's most distinctive feature: residents can deduct their federal income taxes paid from Louisiana taxable income. This deduction significantly reduces the effective Louisiana rate for middle and higher earners — the higher your federal tax bill, the more of it you can deduct from Louisiana income.
Social Security Exemption
Louisiana does NOT tax Social Security benefits — 100% exempt from Louisiana income tax at all income levels.
No Local Income Taxes
Louisiana parishes (counties) and cities do not impose local income taxes. New Orleans, Baton Rouge, Shreveport — no local income tax in any Louisiana city. This differs from states like Ohio (city income taxes up to 2.5%) or Missouri (St. Louis/KC 1%).
Property Tax
Louisiana property tax effective rate approximately 0.51% — among the lowest in the United States. The homestead exemption ($75,000 off assessed value for primary residences) significantly reduces most homeowners' property tax bills.
No Estate or Inheritance Tax
Louisiana has no estate tax and no inheritance tax.
Introduction
Louisiana was once known for having some of the most complex income tax rules in the South — including a unique (and lucrative) deduction for federal income taxes paid. In late 2024, Governor Jeff Landry signed sweeping tax reform that collapsed Louisiana's graduated income tax into a flat 3% rate effective 2025. This reform, combined with Louisiana's pre-existing advantages (no Social Security tax, federal tax deductibility, very low property taxes), makes Louisiana one of the more tax-friendly states in the South — particularly at lower and middle income levels. This guide explains Louisiana's reformed tax structure and what departing residents need to know.
Section 01
Louisiana's 2024 Tax Reform and Current Structure
Louisiana's 2024 tax reform fundamentally changed the state's income tax landscape:
The Old System (Through 2024)
Louisiana's pre-reform individual income tax used graduated rates: 1.85% (first $12,500 single), 3.5% ($12,501–$50,000), 4.25% ($50,001–$150,000), and up to 6% above that — though the federal deductibility significantly reduced effective rates throughout. The complexity of the federal deduction interaction made Louisiana's effective rate hard to calculate.
The New System (2025 Forward)
The 3% flat rate applies to all Louisiana taxable income — wages, investment income, self-employment income, rental income. Combined with the federal deduction, the effective Louisiana rate for many residents is well below 3%:
Income Level
Approximate Federal Tax
Louisiana Taxable After Federal Deduction
Louisiana Tax (3%)
Effective Louisiana Rate
$60,000 (single)
~$6,500
$53,500
~$1,605
~2.7%
$120,000 (single)
~$19,000

~$3,030

$300,000 (single)
~$81,000
$219,000

The federal deduction makes higher earners' effective Louisiana rate lower than 3% despite the flat nominal rate.
Louisiana vs Texas Comparison
For Louisiana residents considering a move to Texas: Texas has no income tax but a much higher property tax rate (~1.6% vs Louisiana's 0.51%). At $150,000 income on a home worth $350,000:
Louisiana: income tax ~$3,000 (after federal deduction) + property tax ~$1,785 = ~$4,785
Texas: income tax $0 + property tax ~$5,600 = ~$5,600
Result: Louisiana is actually less expensive in combined income + property tax for many middle-income homeowners vs Texas
For high earners (above $300,000) or non-homeowners, Texas becomes more advantageous. The break-even depends heavily on home value and income level.
Section 02
Louisiana Residency Rules and Exit Planning
Louisiana uses domicile-based residency:
Louisiana Residency
Louisiana defines a resident as a domiciliary — someone whose permanent home is Louisiana — or a person who spends more than 6 months (183 days) in Louisiana. The 183-day test is the statutory path to residency beyond domicile. Departing Louisiana residents should: change domicile to the new state, update driver's license and voter registration, change vehicle registration, and spend fewer than 183 days in Louisiana in the departure year. Louisiana does not have particularly aggressive residency enforcement compared to California or New York.
The Federal Deduction on Departure Year Returns
A key consideration when departing Louisiana mid-year: Louisiana allows the federal tax deduction on a pro-rated basis for partial-year residents. Your departure-year Louisiana return will cover only the months you were a Louisiana resident — and the deductible federal taxes will be allocated proportionally. If you move from Louisiana to Texas on July 1, your Louisiana return covers January–June income; the federal taxes allocable to that period reduce Louisiana taxable income.
Sales Tax Consideration
Louisiana's state sales tax rate is 4.45%, but local (parish + city) rates add significantly: New Orleans combined rate is approximately 9.45%; Baton Rouge approximately 10.45%; most parishes reach 9–10%. When evaluating a move from Louisiana to Texas: Texas has no income tax but a 6.25% state sales tax + local (often 8–8.25% combined). For high-consumption households, Texas's sales tax slightly exceeds Louisiana's state rate but may be less than Louisiana's combined rates in high-tax parishes.

How does Louisiana's federal income tax deduction work?
Louisiana allows individual taxpayers to deduct their federal income taxes paid (not withheld — actually paid) from their Louisiana taxable income before applying the 3% rate. For example: if you have $100,000 in Louisiana taxable income and paid $18,000 in federal income tax, your Louisiana taxable income is reduced to $82,000 — and you pay 3% × $82,000 = $2,460 in Louisiana income tax. This deduction is dollar-for-dollar: every $1 of federal tax paid reduces Louisiana taxable income by $1. The deduction phases out if you take the federal standard deduction vs itemizing — Louisiana's deduction is based on actual federal tax liability, not itemized vs standard. The deduction makes Louisiana's effective income tax rate significantly lower than the nominal 3% for anyone with a substantial federal tax bill.
Q
Does Louisiana tax pension income or IRA distributions?
Louisiana provides a $6,000 exemption per taxpayer (age 65+) for retirement income — this is a modest exemption covering some pension or IRA distributions. Social Security is fully exempt at all income levels. Military retirement income is fully exempt. Public employee pension income from Louisiana state or local government systems (LASERS, TRSL, Municipal Police) is fully exempt. Federal pension income (CSRS/FERS) for federal civil service retirees: Louisiana provides a $6,000 exemption. Private sector pension and IRA/401(k) distributions: subject to the $6,000 exemption for age 65+. After the $6,000 exemption, Louisiana's 3% rate applies — and the federal tax deduction further reduces the effective rate. Louisiana is moderately retirement-friendly — not as generous as Iowa's near-universal retirement exemption, but better than states that fully tax all retirement income.
Q
Is Louisiana a good alternative to Florida for retirees?
Louisiana vs Florida for retirees: Florida has zero state income tax and no estate tax. Louisiana has a 3% flat rate (reduced by federal deductibility to ~2–2.5% effective for most retirees) with Social Security and military retirement fully exempt. The financial comparison at $80,000 retirement income: Louisiana income tax ~$0–600 (depending on pension composition and federal deduction); Florida $0. The real differentiator for retirement decisions: property taxes. Louisiana's 0.51% effective rate with the $75,000 homestead exemption means a $400,000 home pays ~$1,600/year in property tax. Florida's ~0.86% effective rate on the same home: ~$3,440/year. For retirees owning valuable homes, Louisiana's extremely low property taxes can offset the small income tax advantage Florida holds. Both states offer warm climate and no estate tax.
