Short-term vs long-term gains in Arizona

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 $12,314 of tax if you sell short-term against $8,438 if you hold past one year, a difference of $3,877. Arizona also treats the two differently: 2.5% on short-term gains and 1.9% on long-term gains.

How we estimate Arizona tax

2.5% flat rate; 25% of long-term gains can be subtracted (≈1.875% effective). 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.
