We are having a problem with our GST displaying incorrectly, and was wondering if anyone else had the same problem and a way to fix it?

We have setup a shop, and everything has a 30% discount applied to every product.

When you go to checkout your cart, the GST is coming up as 1/11th of the value of the products, not 1/11th of the amount the customer will actually pay.

E.g. If I purchase product worth $100.00 and there is $9.85 shipping costs, GST is being displayed at $10.99, but the customer is only getting charged $70 ($100 minus discount) plus the $9.85 shipping cost which would put there GST at $7.99.

Does anyone know of a way to fix this problem?? This is a major issue for us.

Thanks in advance.

What is GST?
Which version of VP-ASP are you using?

I think you are saying that the discount should not be taxed, but it is getting taxed. This is a bug that is fixed in a patch released for version 5.50. See this posting: http://www.vpasp.com/virtprog/vpaspforum/topic.asp?TOPIC_ID=3358

I think you are also saying that you would like the tax to include the shipping cost? This is controlled by the xtaxincludeshipping configuration.

Is the GST rate 1/11 (~9%)? If so, I can't follow the calcs you gave.
($100.00 + $9.85) / 11 = $9.99 instead of $10.99
($100.00 - $30.00 + $9.98) / 11 = $7.27

I was having the same problem when discounts and coupons were used. Support sent me this and it fixed the problem. I'm using version 5.5 but 4.5 had the same problem so this may work for most versions.

If you want to charge tax on the after coupon/discount price then you
would need to change line 56-58 of shopcartformat.asp from:

Then in your shoptax.asp file change:


If you dont want to tax shipping costs then change it to:
taxtotalamount=total - shippingcost


Hope this helps .. Dale

Version 5.50 has a bug-fix patch for this as I listed in the bug report in the link above (http://www.vpasp.com/virtprog/vpaspforum/topic.asp?TOPIC_ID=3358
). For other versions, the info Dale listed comes in handy.
