Portugal Fuel Prices 2026: ISP Tax, Regional Variation & Atlantic Island Exception
Portugal consistently sits between Spain (cheaper) and France/Germany (more expensive) in the European fuel price ranking — a reflection of its ISP excise rate, which is below France and Germany but above Spain. In 2026, mainland petrol averages approximately €1.68–1.76/litre, making Portugal broadly competitive with central European countries. Its Atlantic island territories — the Azores and Madeira — are significantly cheaper, benefiting from autonomous region tax rules and EU Outermost Region status.

Portugal's ISP fuel tax structure
Portuguese fuel prices are governed by the ISP (Imposto sobre os Produtos Petrolíferos e Energéticos — Tax on Petroleum and Energy Products). The structure:
| Component | Petrol 95 (€/l) | Diesel (€/l) |
|---|---|---|
| Wholesale (crude + refining) | ~0.54 | ~0.55 |
| ISP excise (mainland) | 0.5870 | 0.3974 |
| Carbon component (within ISP) | ~0.048 | ~0.056 |
| Retail margin + distribution | ~0.06 | ~0.06 |
| IVA (VAT) at 23% | ~0.29 | ~0.24 |
| Total pump price | ~€1.68–1.76 | ~€1.55–1.65 |
Portugal applies 23% VAT on fuel — the highest standard VAT rate in continental EU countries alongside Sweden and Finland. This partly offsets the lower ISP rate relative to France (20% VAT) and Germany (19% VAT). Portugal's diesel excise (€0.3974/litre) is notably lower than its petrol excise, reflecting the historical EU and national policy of favouring diesel for commercial transport.

Pump price trend 2020–2026
| Year | Avg petrol 95 (€/l) | Avg diesel (€/l) | Key driver |
|---|---|---|---|
| 2020 | 1.25 | 1.13 | COVID demand collapse; low crude |
| 2021 | 1.48 | 1.35 | Recovery rebound |
| 2022 | 1.96 | 1.97 | Russia-Ukraine spike; temporary rebate applied |
| 2023 | 1.76 | 1.72 | Crude normalisation; rebate ended |
| 2024 | 1.69 | 1.61 | Moderate crude; EUR stable |
| 2025 | 1.57 | 1.48 | 2025 crude decline |
| 2026 (avg) | 1.72 | 1.60 | Partial crude recovery |
Like Spain and France, Portugal introduced temporary fuel rebates in 2022 to cushion the Russia-Ukraine price spike. The government applied a 15–20 ct/litre temporary ISP reduction from April 2022, phased out through early 2023. Economic analysis suggested approximately 25–35% of the rebate was absorbed as supply chain margin rather than fully passed to consumers — consistent with findings across Europe.
Azores and Madeira: the Atlantic island discount
Portugal's autonomous Atlantic regions apply significantly lower fuel taxes:
| Region | ISP reduction | Typical pump price vs mainland | Reason |
|---|---|---|---|
| Azores (9 islands) | ~50–60% ISP reduction | ~25–35 ct/l cheaper | EU Outermost Region; autonomous fiscal powers; island supply cost offset |
| Madeira | ~25–30% ISP reduction | ~10–18 ct/l cheaper | Autonomous region; EU Outermost Region |
| Mainland Portugal | Standard rate | Reference | — |
The EU Outermost Region framework (Article 349 TFEU) recognises the structural disadvantages of remote island territories and permits fiscal measures — including reduced fuel taxes — that would otherwise violate EU state aid rules. The Canary Islands (Spain) benefit from the same framework. For the Canary Islands comparison, see our analysis of Spain fuel prices 2026.
Motorway and branded vs independent pricing
Portugal's motorway service areas (areas de serviço) are operated by concession holders under BRISA and other operators and charge significantly above urban prices — typically 15–25 ct/litre. Independent "posto de combustível" (unbranded stations) and supermarket forecourts (Pingo Doce, Continente, Intermarché fuel stations) are typically the cheapest options, often 5–10 ct/litre below Galp, BP, or Repsol branded stations.
Portugal vs EU neighbours (2026)

Frequently asked questions
-
What is the petrol price in Portugal 2026?
- Mainland Portugal petrol 95 averages approximately €1.68–1.76/litre and diesel €1.55–1.65/litre in 2026. The Azores are ~25–35 ct/litre cheaper and Madeira ~10–18 ct/litre cheaper due to autonomous region ISP reductions. Motorway service areas charge 15–25 ct/litre above urban forecourts.
-
Why is fuel cheaper in Portugal than France?
- Portugal's ISP excise (~€0.587/litre on petrol) is lower than France's TICPE (~€0.682/litre), creating a ~5–10 ct/litre structural price advantage. Portugal's 23% VAT is slightly higher than France's 20%, partially offsetting the excise advantage. Net result: Portugal is typically 5–12 ct/litre cheaper than France.
-
Are fuel prices cheaper in the Azores and Madeira?
- Yes. The Azores apply ~50–60% reduced ISP rates, making petrol ~25–35 ct/litre cheaper than mainland Portugal. Madeira applies ~25–30% reductions, saving ~10–18 ct/litre. Both benefit from EU Outermost Region status permitting fiscal exemptions not available on the mainland.
