Trying to get a query to determine a tax rate based on the province on a
record.
It should look at the [Prov] field and based on what is in that field come
up with the corresponding tax rate. eg IIf ([Prov]= "ON" and [Date of
Service]>2010/06/30,.13,.05, OR IIf ([Prov]="BC" and [Date of
Service]>2010/06/30,.12,.05) or something of this nature. I am not sure how
to write the formula could someone help.

You may find it easier to write a function and pass the Province and Date as
parameters to the function...

Reading between the lines, try something like:

Switch([Prov] = 'BC', IIf([Date of Service] > #2010-06-30#, .12, .05),
[Prov] = 'ON', IIf([Date of Service] > #2010-06-30#, .13, .05),

....
)

I think your best and easiest method is to create a RateTable of criteria and
tax rate like this --
Prov RateStart RateEnd Rate
ON 6/30/2010 0.0415
BC 6/30/2010 0.049
ON 5/10/2010 6/30/2010 0.0415
BC 4/23/2010 6/30/2010 0.049

And then this IIF statement ---
IIF([YourTable].[Prov] = [RateTable].[Prov] AND [YourTable].[Date of
Service] Between [RateTable].[RateStart] AND Nz([RateTable].[RateEnd],
#12/31/9999#)

Build a little, test a little.

I tried to copy this into the query but kept comming up with invalide use of
] or !. Can this also do the other provinces within the same field? This
field name is TaxRate.

Thank you. But I need this in a query with 7 Provinces and each changeing
rates as of 2010/06/30. NO luck with trying to copy and paste the function
into the equation builder - I am a rookie at this so I need more help if
possible.

Hopefully you realize that the ... in there was to indicate it wasn't
complete.

Your Switch statement can be expanded for as many provinces as you like:

Switch([Prov] = 'BC', aaaa, [Prov] = 'AB', bbbb, [Prov] = 'SK', cccc, [Prov]
= 'MB', dddd, [Prov] = 'ON', eeee, [Prov] = 'QC', ffff, [Prov] = 'NB', gggg,
[Prov] = 'NS', hhhh, [Prov] = 'PE', iiii, [Prov] = 'NL', jjjj)

For those provinces that aren't getting HST, bbbb, cccc, etc can simply be
the PST rate. For those provinces that are getting HST, aaaa, eeee, etc will
be an IIf statement that decides whether to use the old PST rate or the new
HST rate.

On the other hand, having the data in a table (as Karl suggested) or calling
a function (as I originally suggested) is a far better approach.
