Answer: $0
Step-by-step explanation:
We should note that based on the information given, Robert and Becca file jointly, therefore, their their capital gains tax be in the current year will be $0.
Assuming they filed separately, their capital gains tax be in the current year will be:
= 15% × ($28,000 - $17,000)
= 0.15 × $11000
= $1650.
But regarding the question, the answer is $0.
