At the federal floor, the state tax barely exists

Louisiana has no minimum wage statute of its own, so hourly workers fall back on the federal $7.25 floor and the federal overtime rule after 40 hours in a workweek. State wage law still requires employers to tell each worker the wage amount, the payment method and the pay frequency. Covered employers also keep time records under the Fair Labor Standards Act.

A full-time week at $7.25 comes to $290 before anything is withheld. Over 52 weeks that is $15,080. The Louisiana Department of Revenue's 2026 withholding rule lets a single worker's first $12,875 pass untaxed, so only about $2,205 of that year is exposed to the 3% rate. That works out to roughly $66 of state tax for the whole year, spread across 26 checks in amounts small enough to miss.

Federal income tax, Social Security at 6.2% and Medicare at 1.45% take far more from a minimum-wage check than Louisiana does. At this level the state line is close to a rounding error, which is what the deduction was designed to do.

Why the deduction is $12,875 on your check but may not be on your return

The statutory base is $12,500 for single and married-filing-separately taxpayers and $25,000 for joint filers, qualifying surviving spouses and heads of household. Since the 2025 reform the state indexes those amounts for inflation each year. For 2026 payroll the department told employers to use $12,875 and $25,750, figures built from CPI data available on December 1, 2025.

The department was explicit that the deduction printed in the 2026 IT-540 instructions could differ slightly once complete 2025 CPI data arrived. Withholding is a prepayment; the return controls. A few dollars either way is normal and shows up as a small refund or balance in May.

Employers who want the withholding side and the return side to match should not force it. The two systems are allowed to disagree by design. The annual return is where the state reconciles them.

One rate, three retired brackets and a withholding cushion

Louisiana repealed its 1.85%, 3.5% and 4.25% brackets for tax periods beginning January 1, 2025 and replaced them with a single 3% rate on Louisiana taxable income. The arithmetic on the return is short: $50,000 of taxable income produces $1,500 of basic tax before credits.

The check is a little different. The department has said its withholding formula can include a cushion to reduce underpayments at filing time, so the state line on a wage statement does not have to equal exactly 3% of gross wages. It does not even have to equal 3% of wages above the deduction. Expect it to run close, not identical.

The table ignores credits, other income and the cushion, so treat it as the skeleton rather than the paycheck. What it shows clearly is that the rate never changes; only the amount above the deduction does.

An offshore supply clerk in Lafayette, paid every two weeks

Here is how the pieces land for a single clerk at a Lafayette offshore supply company earning $22 an hour, 40 hours a week, paid biweekly with no pre-tax deductions. Federal withholding, Social Security, Medicare and Louisiana withholding come out. Nothing comes out for unemployment insurance, because Louisiana funds that program through employers on the first $7,000 of each worker's wages.

Figures come from the Online Paystub Louisiana paycheck calculator for 2026. Local taxes, health premiums and retirement contributions are not included.

Compare the state line with the federal one: the $12,875 deduction shelters a meaningful slice of a $22 wage before the 3% applies, so the state share stays small even at this rate. A busy season offshore adds overtime that changes every line at once, which is why the Louisiana paycheck calculator asks for hours as well as the rate.

Higher earners: estimated payments, May 15 and the IT-540

As income climbs, nothing about the rate changes, which is the point of a flat tax. What changes is who has to act. Residents file Form IT-540 by May 15 of the following year, a full month after the federal deadline. Estimated payments become mandatory when expected Louisiana tax after credits and withholding exceeds $1,000 for a single filer or $2,000 for a joint return, due April 15, June 15, September 15 and January 15.

Wage earners rarely cross that line because withholding keeps pace. Someone with rental income, a side business or a 1099 contract alongside wages often does. Louisiana also lists gambling winnings, capital gains and pass-through income as taxable categories, each with its own sourcing rules. A contractor who bills a Port Fourchon operator directly gets no withholding at all, so the record a contractor keeps of each payment becomes the only evidence for the quarterly voucher math.

An extension moves the filing date, not the payment date. Tax still due on May 15 is still due on May 15.

The register is where Louisiana really collects: 5% state plus up to 7% local

The state sales tax is 5%, fixed by statute through December 31, 2029 and scheduled to drop to 4.75% in 2030. Parishes and municipalities add anywhere from 0% to 7% on top, so combined rates run from 5% to 12% depending on where you stand. A $100 purchase with a 4.5% local rate carries $9.50 of tax.

Groceries for home preparation are exempt from the 5% state portion, but most parish levies still apply, so the grocery receipt is never quite tax-free. Online purchases from sellers who did not collect Louisiana tax owe a combined 9.45% consumer use tax. Remote sellers must register once they pass $100,000 in Louisiana sales or 200 transactions in a year. Registered dealers file by the 20th of the month after the reporting period, even for months with no sales.

For a worker the sales tax matters more than the income tax in daily life. Three percent of wages after a $12,875 deduction is small. Up to twelve cents on every dollar spent is not.
