Nathan is divorced, the divorce was final May 3, 2016, and pays his ex-wife $4,000 per month. When their 15-year old daughter (who lives 100% with the ex-wife) reaches 18, the payments drop to $2,800 per month.

Nathan received a Form 1098 Mortgage Interest Statement from Bank of the West indicating $19,700 of interest expense on his mortgage (a qualified acquisition mortgage) Complete Nathans Form 1040, Schedules 1 & 2, Schedule A, Schedule B, Forms 8959 and 8960 . Dont forget he paid state taxes and they should be deducted on Schedule A. If you need to make assumptions, they should be realistic. Hint: Form 8959, lines 7, 18, 22 and 24 should be $873, and form 8960, Line 17 should be $454, and that the total of these additional taxes belong on Schedule 2 (you figure out where on Sch 2), and on line 23 of Form 1040. Line 25d on page 2 of Form 1040 should be $50,873. The additional amount of $873 would have been on his W-2 because his employer would have deducted this amount. Yes, you calculate the $873 additional tax but because it was already withheld by the employer, it is considered tax withheld, a credit towards the tax liability calculated on the tax return.
