D. adjusted gross income
Tax-exempt income is income you don't have to pay taxes on but doesn't account for the income you have to pay taxes on.
Gross income is all of your income without adjustments.
Tax-deferred income is income that you don't have to pay taxes on until a later date but, like tax-exempt income, doesn't account for the income you have to pay taxes on right away.
Net pay is the paycheck you receive after taxes are withheld from your salary.
