Hello Dr Byte,

My tax rate is 10%, & store is setup to include tax in prices.

Example, Item = 0.10 ex gst, 0.11 inc gst, shipping = 0.30 ex, 0.33 inc

Zen cart displays:

Sub-Total: $0.11 Inc GST
Delivery (Australia Post - Flat Rate): $0.33 Inc GST
GST: $0.04 Inc GST
Total: $0.44 Inc GST

This is correct, Paypal states amount to be charged at $0.44, also correct.

Payplay error log is:

[ITEMAMT] => 0.11 *** item amount is correct in gst
[HANDLINGAMT] => 0.04 *** this is my total gst tax amount?
[SHIPPINGAMT] => 0.36 *** not sure what this is?
[TAXAMT] => 0.01 *** this is the products gst,not including shipping gst
[AMT] => 0.44 *** total amount is correct


I was unaware Paypal couldnt handle shipping tax, is there somewhere I could find out how to impliment this manually as you suggest?

Thanks for your help.
