Portugal's own island regions are fully inside the EU — but they charge a different VAT rate than the mainland, and that catches sellers out.
The Azores and Madeira are autonomous regions of Portugal and, unlike a handful of other EU territories, they are fully inside both the EU customs union and the EU's harmonised VAT area — there's no customs declaration needed for a shipment between mainland Portugal and the islands, the same as between any two mainland Portuguese addresses. That's a genuinely different situation from the Canary Islands (Spain) or Ceuta and Melilla, which sit inside or outside the EU customs union in more complicated ways.
Where the Azores and Madeira do differ is VAT. Under Article 349 of the Treaty on the Functioning of the European Union, which recognises them as EU 'outermost regions,' Portugal is permitted to apply reduced VAT rates there to offset the real cost of remoteness. The islands are not VAT-free — they simply charge less than the mainland's standard 23% rate. That matters for anyone invoicing a customer, or setting a shop price, for delivery to an island address.
Portugal applies three VAT bands (standard, intermediate, reduced) in each territory, at three different levels. Confirm the exact current rate for your invoice with Autoridade Tributária e Aduaneira (AT) or your accountant before relying on a specific percentage — rates can change.
| Territory | Standard rate | Intermediate rate | Reduced rate |
|---|---|---|---|
| Mainland Portugal | 23% | 13% | 6% |
| Madeira | 22% | 12% | 5% |
| Azores | 16% | 9% | 4% |
No customs paperwork changes: a parcel from Lisbon to Ponta Delgada or Funchal is a domestic Portuguese shipment for customs purposes, exactly like a parcel to Porto or Faro. You don't need a commercial invoice with an HS code, an EORI number, or an export declaration.
What does change is the VAT you charge, if you're an e-commerce seller. If your invoicing system applies a flat mainland VAT rate to every Portuguese order regardless of destination, an Azores or Madeira order is being invoiced incorrectly — over-charging the customer, or under-remitting to AT, depending on which way the error runs. This is worth checking directly in your shop's tax settings rather than assuming a single Portugal-wide rate is correct.
Physically, expect the same kind of logistics consideration as any island destination: an additional ferry or air freight leg from the mainland is involved, which can add transit time compared with a mainland Portuguese address. That side of the picture — transit time and remote-area handling, rather than tax — is covered in more detail on the general remote and island shipping guide linked below.
No. Both are part of Portugal's customs territory and the EU customs union, so a shipment there is treated as domestic, the same as any other Portuguese address.
Under Article 349 TFEU, both are recognised EU 'outermost regions,' and Portugal is permitted to apply reduced VAT rates there to offset the real costs of remoteness and insularity. It's a rate difference, not a VAT exemption — VAT still applies, just at a lower percentage than mainland Portugal's standard 23%.
No — this is a common point of confusion. The Canary Islands are inside the EU customs union but explicitly excluded from the EU VAT Directive's territorial scope, so different VAT rules apply there entirely. The Azores and Madeira remain fully inside the EU VAT area; they just apply a different, Portugal-set rate within it.
Generally yes, since the shipment needs an additional ferry or air freight connection from the mainland. Treat any transit estimate as subject to that extra leg and to normal service conditions, not a fixed guaranteed number of days.
