go to a certain date and work backwards

Hi there,
I need to create a procedure which will track back from the date entered in a textbox to the previous 6 April (end of tax year). From there I want to take the tax limit for that year and the previous 2 tax years. Any ideas on how I would do this?

i.e.
User enters 8/November/99, therefore go back to 6/April/99, put the tax limit of that year into text1, the tax limit of '98 into text2 and the tax limit of 97 into text3. I have the tax limits stored in a db.

Hey pobuckley
excuse me this is not the project.
So u cant put this in project's forum
put in general VB questions forum i assured u will get
answer in 2 hours.
hey pobuckley dont mind but u shoud follow rules.

R u intrested in cricket ? What u think england can win here in india.I guess another whitewash follows ur way.
Dont mind this also

This wil set year_start to the start of the tax year (assuming my_date is your input date)

VB Code:

year_start = "6/4/" & Year(my_date)
If CDate(year_start) > CDate(my_date) Then
  year_start = DateAdd("yyyy", -1, year_start)
End If

PS: us Brit's dont like cricket... we know we just can't play it!
