Short-term vs long-term gains in Louisiana

Sell within a year and the federal government taxes the gain as ordinary income. On a $50,000 gain with the same income, that means $12,564 of tax if you sell short-term against $9,000 if you hold past one year, a difference of $3,564.

How we estimate Louisiana tax

Up to 3% (ordinary income rates). Where a state taxes gains as ordinary income on a sliding scale, the calculator applies the rate shown above to the whole gain, so for most people it is an upper estimate. Local and city income taxes are not included.
