Answer:
Thus Don’s filing status will be either married filing jointly status or married filing separately filing status.
Explanation:
For this situation Don and Deirdre will be viewed as wedded for the whole expense year as they have been legitimately hitched yet living separated. Likewise they have not settled on any activity or choice to sanction their partition. Wear can't record as head of family as he isn't unmarried and will be not viewed as unmarried.
Wear's dad has a gross yearly pay of 2500+3950 = $6,450. This is over the edge measure of $4,150 set for 2018 returns. In this manner Don's dad can't be guaranteed as a ward and subsequently Don can't document as head of family unit.
Here Don can either elect to file a joint return or file separately (this choice is entirely his). Subsequently Don’s filing status will be either married filing jointly status or married filing separately filing status.
