zero
Explanation:
Melissa will have to add to their taxable gifty amount as it exceed the 15,000 tax exemption per year:
100,000 - 15,000 = 85,000
The goverment states an exclusion per lifetime at 11,400,000
Melissa currently is at 2,000,000 therefore it can kepe with their gift for several years without paying gift taxes as, 2,000,000 + 85,000 = 2,085,000 is still below the lifetime exclusion
