Answer:
$5,250
Explanation:
The child tax credit provides a $2,000 tax credit for every qualifying child under 16, but the amount starts to phase out as the married couple's income is higher than $400,000.
The tax credit phases out $50 for every $1,000 of income over the $400,000 threshold: $415,000 - $400,000 = $15,000 x $50/$1000 = $750 phase out.
total child tax credit = ($2,000 x 3 children) - $750 = $6,000 - $750 = $5,250
