Harry and Hildi Hausman's AGI for the year is $144,130 and they have 3 children under 14. They have itemized deductions of 31,250. 

What is their final tax liability for 2019 after the child tax credit? 

What is the amount that could be deducted as a medical expense (ignoring the AGI floor) if Hulu drives to the John Hopkins Medical Center from Lancaster City for treatment for Parkinson’s disease each month in 2019? 

Hulu also pays $200 out of pocket to the hospital for each trip along with copay on prescriptions of $65 each time. The rest is paid by insurance. Tolls and parking are $33 each trip. For 2019, Peggy received a form 1098-E from her federal student loan that showed that she paid $4,600 in interest. Her W-2 from her employer shows 78,750 in box 1 and $6,200 in box 2. If these are the only items of income and expense for 2019, what will be Peggy’s 1040 show when she files her return using the single filing status? 

Humphrey was very busy in 2020 and forgot to file his taxes or file an extension by July 15, 2020. When he got around to filing his tax return on September 28th, he found that he owed $1,727. How much will Humphrey owe in penalties in addition to the $1,727 for his failure to file and pay on time?
