How the Vape Tax Is Different From Tobacco Duty
How the Vape Tax
Is Different From
Tobacco Duty
Two nicotine duties built on completely different foundations. Tobacco duty uses a specific plus ad valorem structure with annual indexation. The 2026 vape duty is a flat rate per millilitre only. Here is why the rates diverge plus how both reach the shelf.
The UK vape tax is a single flat rate per millilitre of e-liquid. Tobacco duty is a two-part charge with a specific rate per 1,000 cigarettes plus a 16.5% ad valorem component of the retail price. Tobacco duty is indexed to inflation annually. Vape duty is a fixed rate set by legislation with no automatic escalator. Both are paid at source by producers or importers. Both have VAT applied on top. The rates are kept far apart on purpose to preserve the price gap between smoking and vaping which the Treasury treats as a public health priority.
Three figures that separate
the two UK nicotine duties
Each figure below is a different component of the two regimes. Tobacco duty stacks two of them together. Vape duty uses one of them only.
Tobacco specific duty
The specific duty on a 20-pack of cigarettes per HMRC rates for 2025/26. Indexed annually with RPI plus an escalator.
Tobacco ad valorem
The percentage of the retail price added as ad valorem duty on top of the specific rate. Unique to tobacco within UK nicotine duties.
Vape duty flat rate
The proposed flat rate per 10ml of e-liquid set out in the HMRC consultation response. No ad valorem component. No escalator.
Four structural differences that keep the two duties far apart
The UK vape excise duty is often described as a smaller version of tobacco duty. That is not quite right. The two are built on completely different principles. Four structural differences shape how each one reaches the shelf. Understanding them together is the only way to see why tobacco stays the most expensive nicotine product in the UK even after the 2026 vape duty lands.
Difference 1: rate structure
Tobacco duty is a two-part charge. It stacks a specific rate per 1,000 cigarettes on top of a 16.5% ad valorem component of the recommended retail price. A premium cigarette pack therefore pays more ad valorem than a value pack even when both contain 20 sticks. The effect is a floor plus a proportional layer.
Vape duty under the 2026 regime drops the ad valorem component entirely. It is a single flat rate per millilitre regardless of bottle price, brand or nicotine strength. A £3.99 nic salt pays the same duty as a £8 premium nic salt containing the same 10ml. Simpler to administer. Less progressive on price.
Difference 2: indexation
Tobacco duty is increased every UK Budget. The standard uplift is RPI plus a tobacco duty escalator typically set at 2% above inflation. That has made tobacco the single most expensive consumer category in real terms decade on decade.
Vape duty as proposed is a fixed rate set out in legislation. No automatic escalator. No indexation clause. Future Finance Acts may introduce either but the opening rate is static. The gap between the two duties is therefore set to widen over time in tobacco’s direction unless policy changes.
Difference 3: who pays and when
Both duties are paid at source. Producers pay when the product leaves the bonded warehouse. Importers pay when the product clears UK customs. Wholesalers and retailers never interact with the duty directly. The cost is embedded in the wholesale price and passed through to retail.
- Tobacco duty is collected by HMRC under the Tobacco Products Duty Act 1979 plus the Tobacco Products Regulations 2001.
- Vape duty is collected by HMRC under the Finance Act provisions introduced in 2025 with regulations enacted during 2026.
- VAT on top is 20% on the duty-inclusive wholesale price in both cases. Neither duty is zero-rated.
- Registered premises plus bonded warehousing apply to both. Non-compliance is a criminal offence.
Difference 4: the rate gap is deliberate
The single biggest difference is not administrative. It is policy. Treasury documents plus Cancer Research UK briefings make clear that the UK wants to preserve the price gap between smoking and vaping. Tobacco duty is designed to make cigarettes the most expensive nicotine product. Vape duty is designed to raise some revenue plus reduce youth uptake without closing that gap.
On an equivalent daily nicotine basis a 20-pack of cigarettes currently carries around £7.49 of specific duty plus 16.5% of around £13 retail which is around £2.15 ad valorem. Total duty on the pack is around £9.64. An adult vaper getting through one 10ml bottle a day pays £2.20 of vape duty. The duty gap is roughly four to one in favour of vaping. The price gap at retail sits close to five to one once VAT plus retail margins are applied.
Four common features of
UK tobacco and vape duty
Paid at source
Producers or importers pay both duties to HMRC before product leaves bonded warehousing. Consumers never see a duty line on the receipt.
VAT applies on top
Standard 20% VAT is calculated on the duty-inclusive wholesale price. The VAT base includes the duty because the duty forms part of taxable value.
Registered premises required
Bonded warehouse status plus HMRC registration applies to producers and importers under both regimes. Non-duty-paid stock is illegal to distribute.
Retail pass-through
Retailer margins on both products are too thin to absorb the duty. Consumers see the full uplift at the shelf in both cases.
