Answer:
$220,000
Explanation:
The maximum exclusion of the gain on sale of the residence which may be claimed on Ryan's 2019 income tax return will be $220,000($400,000-$180,000) because the principal residence was been sold for the net amount of $400,000 after all selling expenses in which the house was bought in 2002 and on the date of sale, the house had a basis of $180,000 given us the amount of the $220,000 as the maximum exclusion of gain on sale of the residence which may be claimed on Ryan's 2019 income tax return.
