Fair call, I can't argue with any of that logic. My only thought had
been that if the taxes are simple and easily calculated then there's no
extra work to do when the invoice is generated. That advantage probably
wouldn't outweigh some of the points below though.

In general we don't plan on doing sales tax calculation for purchase
orders because it is EXTREMELY complicated. In order to do it
properly, you have to know more about your supplier than a customer
usually does. In some places the taxes are fairly flat and simple, but
even then do you really want the liability of having come up with a
number for the taxes? Either way, the vendor is responsible for tax
collection and the associated liability in most places, so chances are
they won't want your number anyway...
So, yeah, you could make changes to OFBiz to use the sales tax calc
stuff for purchases, but doing so really isn't a best practice from a
business perspective so I don't think such a thing should ever go into
the project. Of course, I'm not really an expert in this field and if
discussion went in this direction it could/would certainly happen.

Hi Iain
I had quick look at this as I'm a kiwi and I'll need the same thing
at point in the future for our GST here, so far all I've found is
calcAndAddTax in CheckOutHelper.java which does nothing if the order
type is not a sales order. I guess that would need to modified to
handle purchase orders and somewhere further down the line would need
to be logged against a different account rather than the 'sales tax
collected' account. You would need to make it fairly flexible as you
probably don't want GST showing up on overseas purchase orders which
would be paid to customs rather than the supplier.
Good luck

Has anyone worked out a method for tracking GST/VAT on purchases
(not sales)?
The code makes a pretty big assumption that SALES_TAX is not
applicable to purchases, so I can't use that plumbing to implement
GST on purchases, as you can with sales. Specifically, if I purchase
GST-ratable products worth $110 from a supplier, then $10 of that
(assuming a GST rate of 10%) is a claimable business expense. I need
this fact recorded somewhere.
I've tried to mess about with Promos and Agreements to "fake" it,
but no luck. Has anyone else solved this problem?
Cheers, Iain
