Answer:
$6,000
Explanation:
Since this sale and the exercise of the options didn't occur in the same year, we must make an adjustment for AMT.
In calculating alternative minimum taxable income (AMT), a taxpayer must add or subtract amounts from regular taxable income due to the different treatment of certain tax items for AMT.
In the year 2019:
market price of the stock = $250 Â
Liza acquired it at = $190,
Therefore, Â
Gain = (Acquired price - market price of the stock) × no. of shares
    = ($250 - $190) × 100
    = $60 × 100 shares
    = $6,000
Liza needs to report this as income under AMT adjustments in 2019. This will be reported in for 6,251.
