Carson's tax liability for 2021 as a 23-year full-time student, who earns from the summer internship and part-time job and receives a qualified dividend is $645.
<h3>What is tax liability?</h3>
Tax liability refers to the amount that a taxpayer is obliged to pay.
The tax liability is a function of the taxpayer's taxable income, tax bracket, deductions, and applicable tax rate.
In this case, we have assumed a flat tax rate of 10% for both Carlson's earned income and the dividend income.
<h3>Data and Calculations:</h3>
Earned income = $14,000
Qualified Dividend income = $5,000
Adjusted taxable income = $6,450 ($19,000 - $12,550)
Tax liability = $645 ($6,450 x 10%)
Thus, Carson's tax liability for 2021 is $645.
