Accepted Answer

Louisiana taxes personal income at a single 3.0% flat rate effective January 1, 2025, imposed by La. R.S. 47:32(A) as amended by HB 1 of the 2024 Second Extraordinary Session. This replaced the prior 3-bracket structure of 1.85% / 3.50% / 4.25% and applies uniformly to all filing statuses.

Question 2

What is Louisiana's standard deduction for 2025?

Accepted Answer

Louisiana replaced its prior itemized-only structure with a $12,500 standard deduction for single, HOH, and MFS filers and $25,000 for married-filing-jointly filers, enacted by HB 10 of the 2024 Second Extraordinary Session (La. R.S. 47:293). Personal exemptions from the prior code were repealed in the same session.

Question 3

Does Louisiana tax Social Security and retirement income?

Accepted Answer

Louisiana fully exempts Social Security benefits from state income tax. It also fully exempts benefits from Louisiana state and federal government retirement systems (LASERS, TRSL, FERS, CSRS, military). Private-employer pension and IRA / 401(k) distributions qualify for an annual retirement income exclusion of up to $6,000 per taxpayer age 65 or older under La. R.S. 47:44.1.

Question 4

Do Louisiana parishes charge a local income tax?

Accepted Answer

No. Louisiana parishes and municipalities do not levy a local income tax. However, Louisiana's state sales tax of 5.0% (effective January 1, 2025, per HB 10 of the 2024 Second Extraordinary Session) combines with local parish and municipal sales taxes averaging 5.11%, giving Louisiana one of the highest combined state-plus-local sales tax rates in the country at approximately 10.11%.

Question 5

What changed in Louisiana's income tax for tax year 2025?

Accepted Answer

HB 1 of the 2024 Second Extraordinary Session enacted a fundamental restructuring effective January 1, 2025: it eliminated the prior 3-bracket progressive structure (1.85% / 3.50% / 4.25%) and replaced it with a single 3.0% flat rate. HB 2 of the same session eliminated the corporate franchise tax. The revenue offset was a 0.55-percentage-point state sales tax increase from 4.45% to 5.0%, effective the same date and reviewed under La. R.S. 47:302.
