I have to create an app that computes the amount income tax that a person has to pay, depending on salary. Income tax should be calculated for each portion of income in each range. Here are the following income ranges and taxe rates:
Not over \$7825=10%income tax
\$7825-31852 = 15%income tax
\$31851-77100 = 25%income tax
\$77101-160850 =28%income tax
\$160850-349700=33%income tax
Over \$349700 =35%income tax
Here is the code so far:

``````Public Class IncomeTaxForm

Private Sub calculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculateButton.Click
Dim IncomeTax As Double = 0
Dim salary As Double = 0

Select Case IncomeTax
Case Is <= 7825
taxResultLabel.Text = (salary * 0.1)

Case 7826 To 31850
taxResultLabel.Text = ((salary - 7826) * 0.15)

Case 31851 To 77100
taxResultLabel.Text = ((salary - 31851) * 0.25)

Case 77101 To 160850
taxResultLabel.Text = ((salary - 77101) * 0.28)

Case 160850 To 349700
taxResultLabel.Text = ((salary - 160850) * 0.33)

Case Is > 349700
taxResultLabel.Text = ((salary - 349700) * 0.35)

End Select

taxResultLabel.Text = String.Format("{0:C}", salary)``````

I keep getting zeros. Do i have to add another equation for each case?

## All 3 Replies Everything you have is fine.

Problem is salary is:

``Dim salary As Double = 0``

Set the salary before entering the select block and remove the last line because your setting it in the select block.

Your never setting the salary. Its 0.

``````Dim SalaryToComputeIncomeTaxOn As Double = 45500

Select Case SalaryToComputeIncomeTaxOn
Case Is <= 7825
SalaryToComputeIncomeTaxOn *= 0.1

Case 7826 To 31850
SalaryToComputeIncomeTaxOn *= 0.15

Case 31851 To 77100
SalaryToComputeIncomeTaxOn *= 0.25

Case 77101 To 160850
SalaryToComputeIncomeTaxOn *= 0.28

Case 160850 To 349700
SalaryToComputeIncomeTaxOn *= 0.33

Case Is > 349700
SalaryToComputeIncomeTaxOn *= 0.35

End Select

LabelTotalIncomeTax.Text = String.Format("{0:C}", SalaryToComputeIncomeTaxOn)``````

ok i appreciate this, but now when i try this i keep getting the same number which is the salary that has been declared.So no matter what number i enter in the salarytextbox. This is what i want to enter, 25000 in the salarytextbox and in the taxresulttextbox it should give me \$3,358.75

i got it thanks.
