Arano:I am referring to both international and local sellers, I have never been invoiced for any GST when I transacted via Trade me
I am sure this has already been discussed in the thread,
The legislation deems a marketplace *for it's overseas vendors* as the supplier for purposes of GST.
Trade Me is included, for their overseas sellers since the 1st of December they are adding 15% GST to the price that the seller sets (overseas sellers don't do autions as I recall, but if you have a look in the TM announceements a few months back they outlined how they were complying anyway). Seller sets price $100, trademe takes $115 from you, gives $100 (less fees) to seller, gives $15 to IRD.
For Aliexpress, all their vendors are overseas and so they add GST to all their sales.
