Louisiana Paycheck Calculator

A flat 3%, replacing the state's former graduated 1.85%-4.25% brackets effective for taxable periods beginning on or after January 1, 2025, per Constitutional Amendment 2, approved by voters in November 2024. The rate is unchanged for 2026, confirmed directly by the Louisiana Department of Revenue's own tax-education FAQ page and cross-checked against Tax Foundation's independently published 2026 state tax table, which lists the identical 3.00% figure. Every Louisiana wage earner pays this same rate regardless of income level, unlike a bracket state where the marginal rate climbs as income rises through successive thresholds.

$12,875 for single filers and those married filing separately, and $25,750 for married filing jointly, qualifying surviving spouse, or head of household — inflation-adjusted from the 2025 base ($12,500/$25,000) per Act 11 of the 2024 3rd Extraordinary Session, per the Louisiana Department of Revenue's own Notice of Intent on withholding tables.

Louisiana's own official withholding formula (LAC 61:I.1501) applies 3.09% rather than the 3.00% statutory rate when computing per-paycheck withholding — a small built-in over-withholding margin similar to how some other states' payroll tables work. This calculator uses the 3.00% statutory rate to estimate your actual year-end tax liability rather than that withholding-only figure.

No — before 2025, Louisiana used a graduated bracket system with rates from 1.85% to 4.25%. Voters approved Constitutional Amendment 2 in November 2024, replacing that structure with the current flat 3% rate effective for taxable periods beginning January 1, 2025.

There is nothing to include, because no such program exists in Louisiana as of 2026. The state has no state-run disability insurance or paid-family-and-medical-leave payroll premium comparable to California's SDI or Oregon's Paid Leave Oregon program. The only state-level withholding this calculator applies for Louisiana is the flat 3% income tax after the standard deduction. If Louisiana ever introduces a comparable payroll premium in a future year, this calculator's underlying engine already supports modeling it as a second, independently wage-capped deduction without any change to how federal tax or FICA are computed.

Married filing jointly gets a $25,750 standard deduction versus $12,875 for single filers — exactly double — which lowers Louisiana taxable income by an extra $12,875 for a married couple at the same rate, saving $386.25 in state tax (3% of $12,875) compared to what two single filers with the same combined income would owe separately.

Louisiana's own state income tax takes a flat 3% of taxable income after the standard deduction, but a full paycheck also loses money to federal tax and FICA, which aren't Louisiana-specific. For a single filer earning $75,000 a year, this calculator shows a combined effective tax rate of about 20.36% — 3% state, roughly 10.2% federal, and 7.65% FICA (6.2% Social Security plus 1.45% Medicare) — applied across slightly different bases. There's no single fixed 'Louisiana takes X%' figure for total withholding, because federal tax is graduated and climbs with income while the state and FICA rates stay flat regardless of what you earn.

A single filer earning $70,000 a year in Louisiana takes home about $56,361.25 annually, or roughly $4,697 a month. That reflects $6,570 in federal tax after the $16,100 federal standard deduction, $1,713.75 in Louisiana's flat 3% state tax after the $12,875 state standard deduction, $4,340 in Social Security, and $1,015 in Medicare — $13,638.75 in total tax, an effective rate of about 19.48%. A married filer at the same household income owes less state tax thanks to the wider $25,750 joint standard deduction.
