How Louisiana treats capital gains

Louisiana taxes capital gains as ordinary income at a flat 3% rate. The estimate subtracts Louisiana's standard deduction ($12,875 single / $25,750 married).

A worked example

Say you are a single filer in Louisiana with $60,000 of taxable income who sells stock held over a year for a $25,000 long-term gain. Federal tax on the gain is $3,750 (all of it lands in the 15% bracket at this income; no NIIT applies below $200,000 MAGI). Louisiana adds an estimated $750, for a combined $4,500, an effective 18.0% on the gain. These figures use the same math as the calculator, 2026 federal brackets per IRS Rev. Proc. 2025-32, and state figures from the Tax Foundation's State Individual Income Tax Rates and Brackets, 2026.
