If the taxpayer or his spouse is deemed dependent on another tax return, the standard deduction which can be granted on the return of the taxpayer is usually limited to the higher of:
1. $1,050 or
2. The individual's earned income for the year plus $350(subject to standard deduction amount of $6,350, in general)
Here while preparing the tax returns of Adam and Amy, they have included April as a dependent. Therefore,April can be taken as a dependent in the tax return since April is still living on the support of her parents. But Adam can get standard deduction as limited as per the law in the return, disclosing April's income.
The standard deduction available is higher of
1. $1,050 or
2. $18,000+$350 but subject to $6,350
Therefore Adam can get a deduction of $6,350.
