Answer:
Using the 2019 tax schedules, the Jacksons should receive a refund of $5,573.
Explanation:
UI used the 2019 tax brackets since no year was given and 2019 is the last one due.
The $50,000 gain resulting from the sale of their house qualifies for exclusion, then it will not be included in their tax liabilities.
AGI = $100,000 (only salary income, no other income reported)
itemized deductions = $16,500
standard deduction for married filing jointly = $24,400 (this is larger, so we will select the standard deduction)
total taxable income = $100,000 - $24,400 = $75,600
total tax liability = $1,975 + [12% x ($75,600 - $19,750)] = $8,677
withheld taxes = $6,250
taxes owed = $2,427
child credits = 4 x $2,000 = $8,000
net tax liability = $2,427 - $8,000 = ($5,573) which are refundable
This means that the Jacksons should receive a refund of $5,573.
(Up to $1,400 of the child tax credit is refundable per child, so up to $1,400 x 4 = $5,600 are refundable)
