The Wine Equalisation Tax (WET) rebate is one of the most important financial mechanisms for small and medium Australian wineries. It offsets the 29% WET applied to the wholesale value of wine at the last wholesale sale, allowing eligible producers to remain competitive. The single biggest change for 2026 is the rebate cap increase, covered below; staying current is essential for maximising your claim while remaining compliant.

What Changed for 2026: The Rebate Cap Increase

From 1 July 2026, the WET producer rebate cap increased to AUD 400,000 per financial year, up from AUD 350,000 (where it had sat since 1 July 2018). If your winery's WET liability for the 2026-27 financial year onward is close to the old cap, this is worth re-checking with your accountant, since it may change how much of your wholesale sales are effectively WET-free.

How WET Works

WET is levied at 29% of the taxable value of wine at the last wholesale sale (or deemed wholesale value for retail and cellar door sales). It applies to all wine sold, used, or applied for own use in Australia.

For a wine with a wholesale value of $10 per bottle, the WET component is $2.90. For premium wines at $30 wholesale, it is $8.70. The tax is significant, and without the rebate, many small producers would struggle to compete.

The WET Rebate

Eligible wine producers can claim a rebate of up to AUD 400,000 per financial year (from 1 July 2026) on the WET they pay. This effectively means that the first portion of a winery's sales is WET-free.

Eligibility Requirements

To claim the WET producer rebate, a producer must:

Be the producer of the wine and be registered (or required to be registered) for GST : there is no separate registration "as a wine producer" with the ATO
Be liable to pay WET on the sale, or sell under quote to a purchaser who will be liable
Own the source product : you must own the source product making up at least 85% of the total volume of the wine throughout the winemaking process
Sell in a retail-ready container : 5 litres or less, branded by a trademark you (or an associated entity) own
Meet the ownership and associate rules : associated entities (common ownership) share a single rebate cap, preventing groups from claiming multiple rebates through separate entities

What Counts as Eligible Wine

The rebate applies to wine you produce and sell, including:

Wine made from your own grapes
Wine made from purchased grapes (contract crushing)
Fortified wine, sparkling wine, cider, perry, and mead

It does not apply to wine you purchase as finished product for resale.

Common Mistakes

Not tracking cellar door valuations correctly

Cellar door sales require a notional wholesale value calculation (typically 50% of the retail price) to determine the WET base. Getting this calculation wrong affects both the tax liability and the rebate claim.

Exceeding the associate cap

If your winery is related to another wine business (common ownership, shared directors), you share a single AUD 400,000 rebate (AUD 350,000 for financial years before 2026-27). Many producers discover this too late after both entities have claimed separately.

Incomplete records for the ATO

The ATO requires detailed records supporting every rebate claim: production records, sales records, grape source documentation, and wholesale value calculations. Incomplete records can delay or reduce your rebate.

Missing the BAS deadline

The WET rebate is claimed through your Business Activity Statement (BAS). Late lodgement means late payment of your rebate, and potential penalties.
