There are various things that could and maybe should be improved about this function, but I'm just doing it fairly quickly to give you the general idea of how to turn something into a VBA function and then use it in a query.

The name should probably be changed. Local variables inside the function should probably be declared and set to the cdbl() version once and for all near the beginning instead of constantly converted throughout. I used Variant in case Nulls come in, although per your message they shouldn't be able to.

You use this in a query like: Expr2: ReturnData([tblEmployees].[Marital Status],[Basic Salary],[Lower],[Exemption credit])


Code: 
Function ReturnData(lngMaritalStatus As Variant, dblBasicSalary As Variant, dblLower As Variant, dblExemptionCredit As Variant) As Double

If Len("" & lngMaritalStatus) = 0 Or Len("" & dblBasicSalary) = 0 Or Len("" & dblLower) = 0 Or Len("" & dblExemptionCredit) = 0 Then
    ReturnData = 0
    Exit Function
End If

If (lngMaritalStatus = "1" And CDbl(dblBasicSalary) > 25727) Then
    ReturnData = CDbl(dblBasicSalary) - ((CDbl(dblBasicSalary) - CDbl(dblLower)) * 0.2) - CDbl(dblExemptionCredit)
ElseIf (lngMaritalStatus = "2" And CDbl(dblBasicSalary) > 17780) Then
    ReturnData = CDbl(dblBasicSalary) - ((CDbl(dblBasicSalary) - CDbl(dblLower)) * 0.12) - CDbl(dblExem

I'm sure I screwed this up because it's not loading to my query yet. I followed what you typed up and made some changes to meet all my requirements. In the query I created this expression: Expr: WiTaxCalc([tblEmployees].[Marital Status],[tblEmployees].[Basic Salary]) And ([tblpayrolltaxes].[Lower]) Please let me know if you need anymore information.

The function requires input for 4 arguments. You provide only 2 then you throw in AND ... . This makes no sense.

Look at Isaac's example again.

I just realized I may have copied some other stuff that shouldn't have been there. I fixed that but have a couple of questions that I will ask Isaac.

Could you please explain what Local variables means? And what does declare and set to the cdbl() version mean and where would I do that?

I reviewed what I had typed up and realized I entered it as sql code instead of following your example. Looks like the only places a problem is appearing now is in the Elseif line. I will attached the code.
Code: 
Function WiTaxCalc(lngMaritalStatus As Variant, dblBasicSalary As Variant, dblLower As Variant, dblExemptionCredit As Variant, dblAmountfromColumnA As Variant) As Double

If Len("" & lngMaritalStatus) = 0 Or Len("" & dblBasicSalary) = 0 Or Len("" & dblLower) = 0 Or Len("" & dblExemptionCredit) = 0 Or Len("" & dblAmountfromColumnA) Then
    ReturnData = 0
    Exit Function
End If

'WiTaxCalc: If(lngMaritalStatus = "1" And CDbl(dblBasicSalary) <25727) Then
              Return Data = CDbl(dblBasicSalary) - CDbl(dblAmountfromColumnA)-CDbl((dblExemptionCredit)),
        ElseIf (lngMaritalStatus = "2" And CDbl(dblBasicSalary) < 17780) Then
               Return Data = CDbl(dblBasicSalary) - CDbl((dblAmountfromColumnA) - CDbl (dblLower)) - CDbl((dblExemptionCredit)),
        ElseIf (lngMaritalStatus = "1" And CDbl(dblBasicSalary) > 25727) Then
                Return Data = CDbl(dblBasicSalary) - CDbl((dblAmountfromColumnA) - CDbl((dblBasicSalary) - CDbl(dblLower)) * 0.2)) - CDbl((dblExemptionCredit)),
        ElseIf (lngMaritalStatus = "2" And CDbl(dblBasicSalary) > 17780) Then
                ReturnData = CDbl(dblBasicSalary) - CDbl((dblAmountfromColumnA)-CDbl((dblBasicSalary) - CDbl(dblLower)) * 0.12)) - CDbl((dblExemptionCredit)),
              
  Else 'all other cases
    ReturnData = 0 '
End If

End Function
 
Local means variable can be accessed only within the procedure where it is declared.

Cdbl() is a function that converts a value to Double data type.

Your function won't work. You have made too many bad edits to the code Isaac provided. The first being the function declared name. Then you put space in Return Data. If you want the function name declared as WiTaxCalc, then you need to change each ReturnData to WiTaxCalc.

If you have no training in writing code, suggest you take a full course somehow somewhere.

Thank you, that hint helped. I wish there was a class by me.

Hi June
With my limited knowledge of VBA is the modified Module enclosed correct?
Code: 
Function ReturnData(lngMaritalStatus As Variant, dblBasicSalary As Variant, dblLower As Variant, dblExemptionCredit As Variant, dblAmountfromColumnA As Variant) As Double

If Len("" & lngMaritalStatus) = 0 Or Len("" & dblBasicSalary) = 0 Or Len("" & dblLower) = 0 Or Len("" & dblExemptionCredit) = 0 Or Len("" & dblAmountfromColumnA) Then
    ReturnData = 0
    Exit Function
End If

If (lngMaritalStatus = "1" And CDbl(dblBasicSalary) < 25727) Then
              ReturnData = CDbl(dblBasicSalary) - (CDbl(dblAmountfromColumnA) - CDbl(dblExemptionCredit))
        ElseIf (lngMaritalStatus = "2" And CDbl(dblBasicSalary) < 17780) Then
               ReturnData = CDbl(dblBasicSalary) - CDbl(dblAmountfromColumnA) - CDbl(dblLower) - CDbl((dblExemptionCredit))
        ElseIf (lngMaritalStatus = "1" And CDbl(dblBasicSalary) > 25727) Then
                ReturnData = CDbl(dblBasicSalary) - CDbl(dblAmountfromColumnA) - CDbl(dblBasicSalary) - CDbl(dblLower) * 0.2 - CDbl((dblExemptionCredit))
        ElseIf (lngMaritalStatus = "2" And CDbl(dblBasicSalary) > 17780) Then
                ReturnData = CDbl(dblBasicSalary) - CDbl((dblAmountfromColumnA) - CDbl((dblBasicSalary) - CDbl(dblLower)) * 0.12) - CDbl((dblExemptionCredit))
              
  Else 'all other cases
    ReturnData = 0 '
End If

End Function
 
You can test your code/functions in the immediate window (press Ctrl+G) and enter the function with some sample values
Code: 
?ReturnData(1, 50000, 25000, 1000, 2500)
This will run your code and return the results. Play with a variety of different values/scenarios to confirm all possibilities. You can also set a break point in your code and use the F8 key to step through line by line.

I'm trying to test my adjusted code in the query to see what it produces. I need to reference 2 tables of data. Does this look right?
Code: 
Expr: WITaxCalc([tblEmployees].[Marital Status],[Basic Salary]) And ([tblpayrolltaxes].[Lower],[Amount from Column A])
I see a bunch of people have jumped in, I will add my two cents when I get back to my computer a bit later today hopefully
[/QUOTE]
I was able to get it to load after many adjustments. After a few tests and a couple adjustment to parentheses locations, i was about to get it to calculate right. I had to stop for tonight and will hit it again tomorrow. Thanks for all your help.
 
You'll need to feed the function, (when using it in the query), every column that matches (in order) the input variables like for example dblLower.

If there are 6 input variables, you'll need to feed it 6 columns when using it see my example.

Thank you. After much trial and error, i got my first one to work. Thanks for the tips on how to get started.

On my Payroll form, I have a button so when I update the Basic Salary, the deductions would recalculate or requery, it's not doing that anymore. When I had my deductions build in 4 IIF statements, my deductions would requery or recalc on the fly. Now that I have a vba calculating my taxes, my salary and requery or recalc will not update on the fly. Does this sound normal or is there something I can do to fix it? Is it due to the vba? Let me know if this should be a new post.

Sounds like you need to requery the Form

I have a Recalculate Taxes button with a code to requery the form frmCDpayrollrecommsub that was working before I calculated my taxes in a vba function. Now I have to go to the next record and back to get it to requery or recalc. I've built a macro to requery the frmCDpayrollrecommsub and attached it to On Got Focus on the main form FrmPayroll which didn't make it refresh, so I tried in on the On Got Focus on the frmCDpayrollrecommsub, which still does nothing when i click the Recalculate Taxes button. The only way I can get it to refresh is to go to the next record and back.

Would a requery Form do something different then what I'm already trying?

I would convert the Forms Macro to Visual Basic
Then enter the following as the last line:- [Forms]![frmPayroll]![frmCDPayrollrecommSub].[Form].Requery

The WI State Tax that is written in VBA is only thing that will not update.
 
Can you post a screenshot of the Code you have on the On Click event of the Recalculate Taxes Button.

If I go to the next record and back, all taxes update except the vba code tax
