Answer and Explanation:
a. The calculation of the robert qualified business income is shown below:
Since robert is the sole shareholder and CEO of the ABC Inc and earned the income of $325,000 after subtracting the deduction of $100,000 salary
Also their is a dividend of $250,000
But the qualified business income should be equivalent to the net income i.e. $325,000
b. In the case when there is $200,000 so the net income would be decreased by $100,000
Now the qualified business income is
= $325,000 - $100,000
= $225,000
