Total annual gross income = $45500
Total exemptions = $3000
So, total taxable income = [tex]45500-3000=42500[/tex]
For an amount up to $2500, rate of interest = 1.5%
So , [tex]\frac{1.5}{100}\times2500[/tex] = 37.50
For amount above $2500, rate of interest is = 3%
Hence, amount to be calculated on 3% is [tex]42500-2500=40000[/tex]
So 3% of 40000 = [tex]\frac{3}{100}\times40000[/tex] =1200
Hence, total tax becomes = [tex]1200+37.50[/tex] = 1237.50
Hence annual tax is $1237.50
