Sources and how we calculate

Published by Financial Calculator. Editorial policy. Publisher attribution, not a claim of professional review.

Louisiana brackets and standard deduction come from the Louisiana revenue department's published 2026 figures (rolling verification recorded in our data files). City and county income taxes are not included.

Figures last checked on November 10, 2026. Read our calculation methodology for data sources and update schedule.

How We Calculate & Keep This Accurate

We subtract the 2026 standard deduction from gross income, walk the federal brackets, then apply the Louisianastate standard deduction and flat rate to the same income. The combined marginal rate adds both top rates because both taxes hit the same dollar. Credits, pre-tax deductions, and local taxes are not included; the paycheck calculator models those.

Louisiana tax bracket FAQs

Common questions about Louisiana and federal income tax brackets in 2026.

What is the Louisiana income tax rate in 2026?

Louisiana has a flat 3.00% state income tax rate in 2026, on top of the federal brackets.

How much tax do I pay on $75,000 in Louisiana?

A single filer earning $75,000 in Louisiana pays about $7,670 in federal income tax and $1,875 in Louisiana tax — $9,545 combined, an effective rate of 12.7% (standard deduction, no credits).

What is the difference between marginal and effective tax rate?

Your marginal rate is the rate on your last dollar of income; your effective rate is the average across every dollar. Only income inside a bracket is taxed at that bracket's rate, so moving into a higher bracket never makes your whole income get taxed harder.

Does Louisiana have local or city income taxes?

This page shows the Louisiana state income tax only. Some cities and counties charge their own income taxes; check our city tax pages or your local revenue department.
