Same problem here. My 1.3.8a shop is up and running, and the tax calculation is wrong when discounts are used.

Goods and postage are taxable goods, VAT 22 %, as required by our officials. The costs are fed into ZC without tax. Tax is set to show everywhere. Here only B-to-B prices are shown at 0 % VAT, for consumers the totals have to be shown.

When a discount is applied, the VAT is undercharged. It should be 18.03 % calculated from the gross, but it varies around 17.5 %. I can't give those invoices to my bookkeeper, but have to rewrite them!

I have several different discounts running on my cart including quantity discounts and group discount

my tax is being calculated on the subtotal BEFORE any of the discounts and I need it to apply the discounts before calculating the tax

does any one have any ideas how I can do this or where the code is that calculates the tax?

thanks

Using recalculate tax reduces the amount of tax based on the size of the discount. But the initial figure is based on the subtotal before discounts.

Be sure to get recent copies of Quantity Discounts and Group Discounts (the latter may involve upgrading your cart) - the tax logic has been refined over time.

sorry this is probably a daft question but what/where is recalculate tax?

thanks

[rlparker]

if I set the discounts to recalulate the tax I am getting some very odd results.

Does anyone know what bit of code I need to edit to calculate the tax after the discount has bee subtracted?

thanks
