GST/VAT in Microsoft-managed countries

This is a useful discussion, especially for publishers trying to understand how GST is handled when Microsoft manages the tax collection. The reporting in Partner Center is particularly important because it helps publishers distinguish the sale amount, tax collected and final payout. For anyone who needs to quickly double-check GST amounts for New Zealand transactions, I also use the https://nzpayecalculator.nz/gst-calculator-nz/ as a simple reference for calculating 15% GST and GST-inclusive/exclusive amounts. Of course, the actual tax treatment should be confirmed with a qualified tax adviser or Inland Revenue.
