Whisky duty and VAT explained

How UK alcohol duty and VAT make up a whisky's shelf price, with worked 70cl examples at 40% and 46% ABV and the current HMRC rates and bands.

Two separate taxes sit inside the shelf price of a bottle of whisky in the UK: alcohol duty, which is charged on the amount of pure alcohol in the bottle, and VAT at the standard 20% rate, which is normally already included in the price you see. Duty is part of the value VAT is charged on, so the two multiply rather than simply add.

This guide covers ordinary UK retail sales of standard-strength spirits. Rates below are those in force from 1 February 2026, checked against HMRC’s duty guidance on 26 October 2026. For a live calculation on a specific bottle, use our whisky tax calculator. This is general information, not tax advice.

What is alcohol duty on whisky?

Alcohol duty is a tax on the pure alcohol a product contains, not on its price, age or flavour. The calculation is:

litres of liquid × ABV as a decimal × duty rate per litre of pure alcohol

For spirits over 22% ABV, which covers virtually all whisky, HMRC’s rate from 1 February 2026 is £33.99 per litre of pure alcohol. Duty generally becomes due when the product is released for consumption in the UK, which is why it is normally invisible inside the shelf price rather than added at the till.

Two details of HMRC’s method matter for worked examples. The duty is worked out on the quantity concerned, and the resulting figure is rounded down to the nearest penny. A producer’s actual return covers the whole released quantity, so a single-bottle calculation is an illustration of the share, not necessarily the exact line in someone’s tax return.

Age, rarity, packaging and awards do not appear anywhere in the formula. A 40% ABV blend and a 40% ABV single malt of the same size carry the same duty. Reduced rates exist for some drinks, but none of them touches whisky: Small Producer Relief and the draught relief both apply only to products below 8.5% ABV.

One caution when comparing figures online: official explainer pages can lag behind rate changes. When the £33.99 rate was checked on 26 October 2026, GOV.UK’s general consumer page on alcohol tax still quoted the superseded £32.79 rate from February 2025. HMRC’s dedicated duty table, linked above, is the authoritative source.

A 70cl bottle worked example

Take a standard 70cl bottle at 40% ABV, using the rate in force from 1 February 2026:

1. Pure alcohol: 0.70 litres × 0.40 = 0.28 litres
2. Duty: 0.28 × £33.99 = £9.5172
3. Rounded down to the nearest penny: £9.51

At 46% ABV, the same bottle size contains 0.70 × 0.46 = 0.322 litres of pure alcohol, and 0.322 × £33.99 = £10.94478, which rounds down to £10.94.

Note the direction of the rounding: HMRC rounds down, so £9.5172 becomes £9.51, not £9.52. The difference is a fraction of a penny on an illustrative bottle, but it is the difference between describing HMRC’s method and not describing it.

Where VAT fits in the shelf price

VAT at the standard rate of 20% is normally included in the ticket price, and it is charged on a value that already contains the duty. VAT Notice 700, section 7.7 confirms that excise duty forms part of the taxable value. This is the sense in which whisky is taxed twice: VAT is levied on the duty as well as on everything else.

Because the shelf price includes VAT, extracting it means dividing by six, not taking 20% off the top. For a £30.00 bottle:

1. VAT: £30.00 ÷ 6 = £5.00
2. Price before VAT: £30.00 − £5.00 = £25.00
3. Illustrative duty at 40% ABV: £9.51 of that £25.00
4. Everything else: £25.00 − £9.51 = £15.49

That £15.49 is not profit. It has to cover the liquid, years of warehousing, glass, labels, bottling, transport, the retailer’s costs and everyone’s margins combined. The split also shifts with the shelf price, because duty is fixed per unit of alcohol while VAT scales with the price:

The duty line never moves, because the alcohol content has not changed. That is why tax makes up nearly half the price of a £30 bottle and a much smaller share of a £100 one. Our guide to why whisky prices differ picks up the non-tax reasons.

What can change the calculation?

• Strength and size. Duty tracks pure alcohol, so a 46% bottling carries more duty than a 40% one, and a 1-litre bottle more than a 70cl. Diluting to a lower strength before bottling does not reduce the total duty, because the same alcohol is still being released.
• Rate changes. Duty rates are set at Budgets and have changed repeatedly in recent years; the £33.99 rate dates from 1 February 2026 and is not a permanent fact. Recheck HMRC’s table after every Budget, and expect this guide and the tax calculator to be updated together when rates move.
• Imports. Goods brought in from abroad have distinct valuation rules and possible customs charges; HMRC’s import VAT guidance covers that territory, and our guide to bringing whisky home covers personal allowances.
• Duty-suspended storage. Whisky held in an excise warehouse has not escaped duty; the charge is generally deferred until release for consumption. That matters if you ever buy a cask: bottling and release from duty suspension are not necessarily the same event.
• Minimum pricing. Scotland and Wales set a legal price floor per unit of alcohol. That is a separate public-health measure, not a tax: nothing is paid to the government as a minimum-pricing charge. The minimum unit pricing guide explains the difference.
