What is the Louisiana state income tax rate in 2026?

Louisiana taxes income at a flat 3.00% in 2026. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $290 of Louisiana income tax (0.3% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $695 to Louisiana and $4,111 federal. The schedule, how Louisiana treats each kind of retirement income, and its local taxes follow.

In QuantCalc's 51-state planner study — one married couple, both 60, $2M, $80,000 a year to spend after tax, 10,000 paths per jurisdiction — the median path in Louisiana pays $196,443 of federal and state income tax and Medicare IRMAA over 30 years, $34,492 of it Louisiana state income tax, $33,846 more than in the 16 jurisdictions that charge this couple no state tax. That ranks #23 of 51 by lifetime tax (1 = lowest). The plan succeeds in 83.27% of paths. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.

The LA verdict

For a retiree planning withdrawals in 2026, Louisiana is broadly retirement-tax-friendly. One flat bracket since the 2025 reform, with state and federal pensions fully exempt and private pension and IRA income excluded up to a cap from age 65.

Louisiana allows a retirement-income exclusion of up to $24,648 for a couple from age 65. A traditional→Roth conversion draws on that same exclusion from age 65, so converting inside the cap can cost nothing at the state level.

Live ACA cliff check

The 400% FPL cliff is a federal threshold, but the dollars at stake depend on your county's benchmark Silver premium. Adjust the inputs below — every result is computed in your browser, no data is sent to QuantCalc.

Worked example: $30k Roth conversion in Louisiana

Consider a married couple age 58 in Louisiana with $75,000 of wages (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Louisiana state tax on that conversion is $900 — 3.0% of the amount converted. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $23,441 a year at Louisiana's average benchmark Silver premium. Total cost of the $30,000 conversion: $27,941, or an effective 93.1% marginal rate. Each Louisiana tax figure for a conversion on this page is QuantCalc's state tax engine run on the couple's whole 2026 Louisiana return twice, without the conversion and with it, with every amount split evenly between the two spouses, so Louisiana's own brackets, deductions, exemptions and credits are all applied. The federal-state-ACA stack matters in Louisiana.

Cost breakdown

ComponentAmount
Federal income tax (12% bracket)$3,600
Louisiana state income tax$900
ACA premium tax credit clawback$23,441
Total cost on $30,000 conversion$27,941 (93.1% effective)

Scenario B (friendly): $50k post-65 conversion in Louisiana

A married Louisiana couple age 67, both on Medicare, with $40K pension income converts $50,000 in a single year. State tax owed: $1,190 — 2.4% of the amount converted. Federal income tax added: $4,607 ($7,500 of the added income fills deductions their pension left unused and the rest is taxed in the federal 10%–12% brackets). No ACA clawback (on Medicare). Total: $5,797, or 11.6% effective. The post-65 conversion window is where a Louisiana ladder is cheapest.

What the planner's Monte Carlo says about Louisiana

QuantCalc Research ran one married couple through QuantCalc's retirement planner in each of the 51 jurisdictions: both 60, $2,000,000 ($1,400,000 traditional, $600,000 Roth), a 60/40 portfolio, $80,000 a year to spend after tax for 30 years, no Social Security, 10,000 paths each. The planner's federal and state tax engines price every year, and it picks the withdrawals and Roth conversions. Here is Louisiana beside the lowest- and highest-tax results:

MetricLouisianaNo state tax (16 jurisdictions)Oregon (highest)
Median lifetime tax, federal + state + IRMAA (30y)$196,443$162,597$309,718

Rank by lifetime tax (of 51, 1 = lowest)#23#1#51

Across all 51 jurisdictions the success rate runs from 80.61% to 84.05%: for this couple the state changes the tax bill far more than the odds of the money lasting. Dollars are today's dollars.

How Louisiana treats capital gains in retirement

Louisiana taxes long-term capital gains as ordinary income at the same top bracket rate (3.00%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 3.00% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.

Why the ACA cliff hits hard in Louisiana

The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Louisiana's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $22,485 a year of premium tax credit at Louisiana's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.

For 2026 the 400% FPL threshold is:

Roth conversion strategy for Louisiana

The LA-specific playbook depends on tier:

  1. Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
  2. Stay under the cliff if you can. In Louisiana at 3.00%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
  3. If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
  4. Coordinate with capital gains and the 0% LTCG bracket. Louisiana taxes long-term capital gains as ordinary income at the same top bracket rate (3.00%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 3.00% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
  5. Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Louisiana resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

What a year-end move does to your Louisiana and federal tax in 2026

Each move changes three bills at once: the federal return, the Louisiana return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).
