Louisiana rules for construction & trades
- 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
W-2 or 1099 changes everything
On a W-2 your employer withholds tax and may offer a retirement plan. As a 1099 subcontractor you pay self-employment tax and quarterly estimates, but you can deduct tools, materials and job-site driving.
Tools and equipment
Tools, equipment, safety gear and work vehicles used for business are deductible; larger purchases can often be written off in the year you buy them.
Overtime deduction for W-2 workers
Non-exempt W-2 workers can deduct the overtime premium they are paid, up to $12,500 a year ($25,000 joint) from 2025 through 2028, subject to an income phase-out.
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.
A worked example

| Solo 401(k) maximum | $37,511 |
