Designing Around the Millilitre: Reading Ireland's E-Liquid Tax from the Factory Floor

Most people read a tax change as a price change. We read it as a design change. On 7 October 2026 Ireland adds €1 to the standard 20-pack of cigarettes, and from 1 January 2027 it is proposing to raise the e-liquid Products Tax (EPT) by 40% - from €0.50 to €0.70 per millilitre. The headline that matters to a factory isn't the percentage. It's the unit. Ireland charges its e-liquid tax by the millilitre, not by the nicotine - which makes the tax, in practice, a decision about capacity. And capacity is one of the few things on the bill a manufacturer actually controls. Here's how we think about it.

Source: Irish Government / Department of Finance, Budget 2027 (presented by the Minister for Finance on 6 October 2026). Cigarette changes are effective 7 October 2026; the e-liquid change is proposed for 1 January 2027 and not yet in force. Figures are tax amounts, not retail prices. What follows is a manufacturer's interpretation, not official guidance.

1. A Volume Tax Is a Design Tax

The moment you accept that the EPT is charged per millilitre, the conversation changes. It's no longer "the tax went up 40%"; it's "how many millilitres are in this device, and what does each one now cost us at €0.70?" For a manufacturer that's a question we can act on, because capacity is ours to set. A 2 ml pod and a 30 ml reservoir don't just deliver different experiences - at the new rate they carry €1.00 versus €21.00 of tax. Same per-ml price, very different unit economics.

Reservoir / bottle	EPT now (€0.50/ml)	EPT proposed (€0.70/ml)
2 ml	€1.00	€1.40
10 ml	€5.00	€7.00
30 ml (for scale)	€15.00	€21.00

EPT = volume × rate. The 2 ml and 10 ml rows are the government's own examples; 30 ml is shown for scale. The factory lesson is linear: the tax line scales one-for-one with capacity.

2. Three Levers It Pushes at Once

Read against how a product is built, the volume tax pushes on three levers simultaneously. First, capacity: a bigger reservoir means more puffs, but a proportionally larger tax line - the "bigger is better" logic that sold high-puff disposables now has a direct cost attached. Second, form factor: a refillable device lets the user top up, which moves the taxed millilitres from the device into the liquid that's refilled - a different structure and a different footprint, not a dodge, but a shift in where the volume sits. Third, the "nicotine-free" assumption: in Ireland a zero-nicotine e-liquid is taxed the same per millilitre, so offering a nicotine-free variant does not reduce the EPT at all.

3. Fourteen Months In, the Direction Is Set

The EPT is young: introduced by the Finance Act 2024, applying from 1 November 2025 at €500 a litre - the same €0.50 per millilitre. This is the first upward move, and it lands barely fourteen months after the charge began, which had already collected over €22 million by the summer of 2026. For planning, the signal matters more than the number. A tax that can jump 40% within its first year is an input we have to model as moving, not fixed. The cigarette side says the same thing: €0.50 added in the 2026 Budget, €1.00 in 2027 - two budget years running.

4. What We'd Do Differently for This Market

We won't sell you a one-line answer, but here's the order we'd look at it in. First, price the tax into the SKU, not the brand: because it's per millilitre, the right unit to plan against is cost-per-ml of e-liquid, and every SKU's tax line should be re-run at €0.70 before January. Second, keep the tax separate from the retail math - the EPT is a floor input, and VAT and margin sit on top, so "the tax rose 40%" is not the same as "the price rose 40%." Third, hold a compliance file per product: under the EPT the obligations attach to the product's volume and its classification, and that's the kind of paperwork a factory needs ready before the rate takes effect, not after.

5. The Honest Limits of What a Tax Tells You

A per-millilitre tax tells a manufacturer a lot about cost structure and almost nothing about demand. The government frames these rises as public-health - Ireland's adult daily-smoking rate has fallen from 29% in 2007 to 17% in 2025 - and whether a higher tax bends that curve is a question the budget can't answer. It also can't tell us whether a specific product can be sold in Ireland, in what form, or under what labeling; that's the regulatory layer that sits above the tax. And to be straight about timing: the cigarette increase has already landed (7 October 2026), while the e-liquid change is proposed for 1 January 2027 and is not yet law as of this writing. Plan for it, don't assume it.

6. The Takeaway for a Factory

Strip it back and the Ireland read, from the manufacturer's chair, is one line: a volume-based tax turns capacity into a line item on the cost sheet - a line item that can move 40% in a single budget. The factories that handle it well will reprice their SKUs in millilitres, keep the refillable and the high-capacity options distinct on the tax, and have the compliance file ready before January rather than after. What none of this decides is demand; that's the market's to call. The tax just tells us exactly what each millilitre is going to cost us to make.
