Arizona treats long-term gains differently for assets acquired after December 31, 2011 than before.
The 140 instructions read:
You may subtract 25% (.25) of any net long-term capital gain
included in your federal adjusted gross income that is derived
from an investment in an asset acquired after December 31, 2011.
