How Japan's liquor tax reform settles the tax difference on stock in the distribution chain

Japan’s liquor tax is levied at the point of shipment

In Japan, liquor tax is charged when the drink leaves the place of manufacture (the brewery or factory). Bottles sitting in the warehouses or on the shelves of wholesalers and retailers are therefore “duty-paid” goods, on which tax has already been paid at the rate in force when they were shipped. According to the National Tax Agency, which handles national taxes in Japan, liquor tax rates change on 1 October 2026, with increases for some categories and cuts for others. Because tax was settled at shipment, stock already in circulation at the time of the change still carries the old rate. Left as it is, the tax on that stock would be out of step with liquor shipped after the change.

Settling the difference based on stock at midnight

This mismatch is adjusted through “stock-in-hand taxation” and “stock-in-hand tax refunds”. They apply to duty-paid liquor in the distribution chain at midnight on 1 October 2026. For liquor whose rate goes up, the difference is charged as additional tax; for liquor whose rate goes down, the difference is returned. Sellers and others who are required to file offset the additional tax against the amount to be refunded. If the tax due is larger, they pay the balance; if the refund is larger, they receive it back. Either way, the return must be filed by Monday 2 November 2026. The National Tax Agency updated its Q&A on 2 September and also provides a filing guide, a leaflet, an Excel tool for preparing the return and an explanatory YouTube video. The same measure was applied in October 2020 and October 2023. The reference materials include an outline of the April 2017 amendment to the Liquor Tax Act, which shows that this reform is one step in a review carried out in stages over many years.

What European readers should watch

This procedure is carried out by liquor businesses in Japan, and people who buy sake in Europe have nothing to do. It does, however, offer a clue to the stage at which, and the way in which, the price of Japanese drinks is set. Which categories go up and which go down is set out in the National Tax Agency’s leaflet. If you are curious, ask your usual importer or specialist shop whether price revisions in Japan will affect the prices of future arrivals. A change in tax rates does not change what is in the bottle. When new lots arrive from autumn onwards, enjoy them chilled or gently warmed as you always have, and perhaps pay a little attention to the Japanese tax and distribution system behind the price.
