Question

Nathan is married filing jointly has a gross income of $54300 adjustments of $2460 2 exemptions of 16400 and deductions of 16500. How much is his tax

Answer 1

 Gross Income of $54,300, Adjustments of $2460, 2 Exemptions of $16,400, and Deductions of $16,500?

Taxable amount = $54,300 - ( $2460 + $16,400 + $16,500 ) = 84,740.
I don't have the list of the tax bracket. The tax bracket of 2016 and 2017 are also different. Just get the tax bracket and multiply the taxable amount.
