VAT on postage adding to website

Hi is it possible someone can sort my shopping cart out for me please.

I sell items which are 0% VAT, 5% VAT & 20% VAT. when postage is added the postage needs to be the same VAT as the item in the cart.

ie if I sell a 0% item postage needs to be 0%
If I sell a 20% item the postage needs to be 20%
If I sell a mix 1 0% & 1 20% half the postage needs to pay 20% VAT

Can anyone help please. I dont no if I need the website changing or some thing adding

I believe I responded to your e-mail regarding this question. I'll post my response here for others to read:

For your situation, the only solution I have would be to create the shipping tax using a separate Order Total extension. You could do it with Ultimate Fee/Discount, by creating a percentage fee of the shipping cost. So for example:

Product A: 5% fee based on the shipping cost
Product B: no fee (because it's non-taxable)
Product C: 7% fee based on the shipping cost

So if the shipping cost was $25.00, it would result in a fee being added to the order of $25 x 5% + $25 x 7% = $3.00. Note that that would be separate from the Taxes line item, and would not affect tax reports in OpenCart, so it may not work for your situation.
