Bonnie and Jake (ages 35 and 36, respectively) are married with no dependents and live in Montana (not a community property state). Because Jake has large medical expenses, they seek your advice about filing separately to save taxes. Their income and expenses for 2017 are as follows:

Bonnie's salary ........................................................... $ 42,500

Jake's salary ................................................................ 26,000

Interest income (joint) ...................................................... 1,500

Rental loss from actively managed rental property .................. (23,000)

All other itemized deductions:*
