Short-term vs long-term gains in Delaware

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 $14,364 of tax if you sell short-term against $10,800 if you hold past one year, a difference of $3,564.

How we estimate Delaware tax

Up to 6.6% (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.
