Answer:
Maximum amount that can be given to family (including the sons- and daughters-in-law) without using unified transfer tax credit is $390,000.
Step-by-step explanation:
Given the data in the question;
Nathan and Diana are married and they have 3 married children, meaning Nathan and Diana also have 3 daughters/sons in law married to their children. In addition, they have 7 minor grand children.
Number of donees will be ⇒ 3 + 3 + 7 = 13
Now, we know that; The annual gift tax exclusion for 2019-2020 is $15,000 per donee or individual for every tax payer while that of married couple is $30,000.
Meaning Nathan and Diana can give $30,000as a gift to each of their family members without using any of their unified transfer tax credit.
Hence,
Maximum amount that can be given to family (including the sons- and daughters-in-law) without using unified transfer tax credit will be;
⇒ 13 × $30,000
= $390,000.
