PiggySelf-Employment Tax in Louisiana (2026)
Louisiana taxes income at a single flat rate of 3.0%, which makes it one of the easier states to plan for: there are no brackets to climb, so an extra $1,000 of profit is taxed at the same rate as your first $1,000. The federal self-employment tax of 15.3% sits on top of that and is unaffected by where you live.
The federal part is the same everywhere
Self-employment tax replaces the payroll taxes an employer would otherwise split with you. As a freelancer you pay both halves: 12.4% for Social Security, on earnings up to the $184,500 wage base, and 2.9% for Medicare with no cap. Together that is 15.3%, charged on 92.35% of your net profit rather than all of it.
At $100,000 of net profit that comes to $14,129.55 in Louisiana — exactly as it would in any other state. Moving does not change this number.
What Louisiana adds: a flat 3.0%
Louisiana's flat 3.0% makes planning unusually simple: there are no brackets, so the rate on your last dollar of profit is the same as the rate on your first. Set aside 3.0% for the state alongside what you set aside for federal tax and the state side takes care of itself. Note that the flat rate applies to state taxable income, which is not the same as your net profit — deductions and exemptions come first.
What the two look like together
| Net profit | Federal SE tax | Louisiana income tax* | SE tax as % of profit | Combined |
|---|---|---|---|---|
| $40,000 | $5,651.82 | $1,200.00 | 14.1% | $6,851.82 |
| $75,000 | $10,597.16 | $2,250.00 | 14.1% | $12,847.16 |
| $120,000 | $16,955.46 | $3,600.00 | 14.1% | $20,555.46 |
* Illustrative: 3.0% applied to net profit. Your state taxable income will differ from net profit once deductions, exemptions and any other household income are taken into account.
Quarterly payments
If you expect to owe $1,000 or more in federal tax for the year, the IRS expects estimated payments four times a year rather than one bill in April. Missing them triggers an underpayment penalty even if you settle in full at filing. The safe harbor rule is the way out: pay 90% of this year's liability or 100% of last year's, and the penalty does not apply.
Frequently asked questions
What is the self-employment tax rate in Louisiana?
The self-employment tax rate is 15.3% and it is federal, so it is the same in Louisiana as everywhere else. Louisiana separately taxes income at a flat 3.0%.
Is the 3.0% flat rate on top of the 15.3%?
Effectively yes, though they are calculated differently and on different bases. The self-employment tax is federal and applies to 92.35% of your net profit. The state tax is a separate calculation starting from your state taxable income.
Do I make quarterly payments to Louisiana as well as the IRS?
Usually yes. Most states with an income tax expect estimated payments from the self-employed on a similar schedule to the IRS. Check Louisiana's revenue department for the exact thresholds, since they differ from the federal $1,000 rule.
