How to calculate WET and GST on wholesale sales.

Last updated 18 March 2025

There are 2 steps to calculate WET for wholesale sales:

  1. Apply the 29% WET rate to the sale price of the wine (excluding GST).
  2. Calculate the GST on the WET-inclusive price.

If you sell wine by wholesale for a price that includes WET you must show the amount of WET on the invoice given to the buyer. For more information, see:

Example: how to work out the wholesale price

Alison has a winemaking business. She sells grape wine to a bottle shop for $120 a dozen bottles before tax.

Alison works out the total wholesale selling price as follows:

1 dozen wine bottles

$120.00

Plus WET at 29%
$120.00 × 0.29

$34.80

Sub-total

$154.80

Plus GST at 10%
$154.80 × 0.1

$15.48

Total wholesale selling price
$120.00 + $34.80 + $15.48

$170.28

 

End of example

Some wine sellers use commission agents to facilitate their wine sales. Where the agent deducts a fee from the proceeds of sale, this fee doesn't reduce the selling price of the wine.
