Total annual gross income = $45500
Total exemptions = $3000
So, total taxable income =

For an amount up to $2500, rate of interest = 1.5%
So ,
= 37.50
For amount above $2500, rate of interest is = 3%
Hence, amount to be calculated on 3% is

So 3% of 40000 =
=1200
Hence, total tax becomes =
= 1237.50
Hence annual tax is $1237.50
