7) Income tax liability:
Salary = $68,100
Less: Adjustments to income =0
=Adjusted Gross income = $68100
Less: Standard deductions = $18350
=Taxable income =$49750

Ordinary tax liability for taxable income for the year 2019 =$49750
$13850*10/100 =$1385
$49750 - $13850=$35900 * 12/ 100 = $4308
Ordinary tax liability =$1385 + $4308 =$5693
Qualified dividends =$8000 * 15/100=$1200
Total tax liability =$5693 +$1200 = $6893
Working notes for qualified dividends:
First $3000 will be taxed at 0% as long term capital gain, so $11,000 - $3000
=$8000 will be taxed.
Qualified dividend will be tax 15% for taxable income more than $38600.
If tax payer taxable income less than $38600, qualified dividends not taxable.

8) Tax payer self employment tax liability
Maximum earning for social security tax for 2019 will be $132900
Tax payer maximum earning will be =Salary +net profit
=$101,000+ $40,000
=$141,000
Excess of maximum earnings = $141,000 - $132,900
=$8,100
Adjust net profit for social security tax= $40,000 - $8100
=$31900
Social security tax liability= Adjust net profit for Social Security tax* Social security tax
= $31900 * 12.4/100=$3955.60
There is no earning limitation for Medicare tax, full net profit will be used
Adjust Net profit for Medicare tax liability= Net profit * Medicare tax
=$40,000 * 92.35/100
=$36940

Medicare tax= Adjust Net profit for Medicare tax * Medicare tax
=$36940 * 2.9%
=$1071.26
Self employment tax liability = Social security tax liability + Medicare tax liability
= $3955.60 + $1071.26
= $5026.86

Working Notes for self employment tax:
Self employment tax is sum of Social security tax + Medicare tax
Employer and employee will contribute for social security tax 6.2 %+6.2% =12.4%
Employer and employee will contribute for Medicare tax 1.45+1.45 = 2.9%
Employment tax is $12.4%+2.9% = 15.3%
9) Interest received = Maturity value * interest rate
$50,000 * 3/100=$1500.
Bond Discount = Maturity value - Bond purchased amount
$50,000 - $45,000 = $5000
Discounts on bonds receivable per period = Bonds discount / Number of period.
$5000 / 10 period =$500
