Louisiana Income Tax Calculator (2026 Filing Season)
Louisiana has a flat 3% state income tax for the 2025 tax year.
Louisiana scrapped its graduated brackets for a 3% flat tax starting in 2025, with a much larger standard deduction.
We subtract Louisiana's standard deduction ($12,500) automatically.
The same $75,000 income in a no-income-tax state (Texas, Florida, Tennessee…) would owe $0 in state income tax — a difference of $1,875 per year.
We only store your state and filing status — never your income.
