Working Note (1):

Long-term capital gain of $13,100 is offset by long-term capital loss of $12,000. Hence, net long-term capital gain is $1,100($13,100$12,000).

Working Note (2):

$30,000 of interest on private activity bonds and $40,000 of other tax-exempt interest is excluded from gross income. $23,000 of interest income on growth stock is included in gross income.

Working Note (3):

The life insurance proceeds of $800,000 are excluded from gross income.

Working Note (4):

Calculate the amount of loss on rental property.

R is an active participant. Hence, he may deduct a loss of $35,000 ($190,000$225,000) under the rental real estate exception. But, R’s modified AGI of $734,100($650,400+$1,100+$23,000+$60,000) is greater than $100,000. Hence, his loss $35,000 rental real estate is suspended.

Working Note (5):

Calculate itemized deductions.

Calculation of itemized deduction
State and local income taxes$8,900
Gambling losses$8,000
Charitable contributions$13,200
Itemized deductions$30,100

Note: Consumer interest of $4,200 is not deductible. As the assistant is not the dependent of R, Medical expense of $15,000 is not deductible.

Working Note (6):

Calculate regular income tax liability.

Regular income tax liability = (Tax on long-term capital gain of $1,100 + Tax on remaining taxable income of $702,900)=(20%×$1,100)+[$150,689.50 + 37%($702,900 - $500,000)]=$220 +$225,763=$225,983

Working Note (7):

Calculate the amount of incentive stock option adjustment.

Incentive stock option adjustment=Acquired price – Option price=$10,000$4,000=$6,000

Working Note (8):

Determine the AMT exemption (files as single taxpayer).

AMT exemption=$70,300[($748,900$500,000)×25100]=$70,300[$248,900×25100]=$70,300  $62,225=$8,075

Working Note (9):

Calculate the amount of tentative minimum tax.

Tentative minimum tax=(Taxonnetcapitalgain+TaxonRemainingAMTbaseof$739,725)=($1,100 ×20%)+[(26%×$191,100) +($739,725 - $191,100)×28%] =$220+$203,301=$203,521
