Consultants in Louisiana: taxes and retirement for 2026
For independent consultants and fractional executives billing clients directly in Louisiana. Louisiana has a flat 3% state income tax for 2026. Here are the 2026 rules, a worked example and the official sources.
Louisiana rules for consultants
- State income tax (2026)
- Louisiana has a flat 3% state income tax for 2026. For 2026, Louisiana individual income tax is computed at a flat 3% rate. The 2026 estimated-tax worksheet uses a $12,875 standard deduction for single filers ($25,750 married filing jointly or head of household).
- State estimated tax
- You must pay estimated tax if your Louisiana income tax after credits and withholding is expected to exceed $1,000 (single) or $2,000 (joint). Same dates as federal (April 15, June 15, Sept. 15, 2026, and Jan. 15, 2027). Farmers and fishermen with at least two-thirds of gross income from farming or fishing can make one payment by Jan. 15, 2027, or skip estimates by filing and paying in full by March 1, 2027. Underpayments are charged a 12% penalty, figured on each underpayment for the number of days it was unpaid. Form IT-540ES.
- Independent Contractor Voluntary Portable Benefits Act (Act 299 of 2026)
- Starting Aug. 1, 2026, any business or app platform can pay into portable benefit accounts for independent contractors. Payments can come from the hiring party's own funds or from a share of the contractor's pay if the contractor opts in in writing (and can opt out at any time). The law says these payments cannot be used as evidence that the worker is an employee.
- Unemployment insurance ABC test (La. R.S. 23:1472(12)(E))
- For state unemployment insurance, paid work counts as employment unless the hiring business proves all three of these: the worker is free from control, the work is outside the business's usual course or places of business, and the worker is customarily engaged in an independent trade or business.
Federal rules for 2026
Solo 401(k) up to $72,000
A one-person consultancy can contribute a $24,500 employee deferral plus an employer share of about 20% of net self-employment earnings, up to $72,000 in 2026, plus an $8,000 catch-up at 50 or older ($11,250 at ages 60 to 63).
The S-corp trade-off
Electing S-corp status can cut payroll tax, but the salary you pay yourself also sets your Solo 401(k) room. Run both sides before you elect.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
A worked example
| Self-employment tax (sole proprietor) | $21,194 |
|---|---|
| Solo 401(k) maximum | $52,381 |
| SEP IRA maximum | $27,881 |
| Payroll tax saved as an S-corp on a $75,000 salary | $9,719 |
| Solo 401(k) maximum as that S-corp | $43,250 |
Federal figures only, before state and local taxes. Simplified: excludes the QBI deduction and the 0.9% Additional Medicare Tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
