Portuguese VAT is Imposto sobre o Valor Acrescentado, universally shortened to IVA. Three rates apply on the mainland, but Portugal is really three VAT territories in one country — and it operates the strictest invoice-fiscalisation regime in Western Europe on top. This guide covers which schedule applies to your sale, what sits in each band, and the registration, filing and invoicing rules that go with them.
One country, three rate schedules
Artigo 18.º of the Código do IVA sets the mainland rates at 6%, 13% and 23%. The same article — as amended by Lei n.º 12/2022 — expressly allows the Legislative Assemblies of the Autonomous Regions of the Azores and Madeira to fix lower rates for operations located in their territories and for imports cleared through their customs offices. The enabling framework caps the discount at 30% of the mainland figure, and both regions have used the power, but to very different degrees.
The Azores took the full discount. Regional Legislative Decree n.º 15-A/2021/A cut the Azorean standard rate from 18% to 16% with effect from 1 July 2021, alongside an intermediate rate of 9% and a reduced rate of 4% — roughly 30% below the mainland across the board, and the lowest standard VAT rate in the entire European Union. Madeira took a much shallower discount at the top, holding its standard rate at 22% and its intermediate rate at 12%, but matched the Azores at the bottom: Regional Legislative Decree n.º 6/2024/M cut the Madeiran reduced rate from 5% to 4% from 1 October 2024. That last change is the one that trips people up. A great many rate tables online — including some maintained by invoicing vendors — still show Madeira at 5%, a figure that has been wrong for nearly two years.
Which schedule applies to your sale
The decisive question is where the operation is located, not where the seller is registered or where the invoice is printed. Until 2022 this was governed by a standalone statute, Decreto-Lei n.º 347/85; Lei n.º 12/2022 repealed it and folded the rules into Artigo 6.º CIVA (nos. 16 and 17), which applies the ordinary place-of-supply tests with the necessary adaptations. In practice:
- Goods — the rate follows the place where dispatch or transport to the customer begins, or where the goods are put at the customer's disposal. Stock shipped from a warehouse in Ponta Delgada carries the Azorean rate even if the buyer is in Lisbon.
- B2B services — the general rule points at the customer's seat or fixed establishment. A consultancy invoice to a Funchal-registered company carries the Madeiran rate even if every hour was worked in Porto.
- B2C services — generally follow the supplier's establishment, subject to the usual special rules for immovable property, transport, catering and electronically supplied services.
Anyone trading between the mainland and the islands therefore has to maintain three rate sets in their billing system and map every customer or delivery point to the right territory. Certified Portuguese software does this natively. Generic foreign invoicing tools very often do not, and quietly apply 23% to everything — which understates nothing but overcharges island customers and creates a refund problem that is far harder to unwind than getting it right the first time.
What Portugal puts in each band
Two annexes to the VAT Code do the classification work. Anexo I lists the goods and services taxed at 6%, Anexo II those taxed at 13%, and anything absent from both falls to 23% by default. Two areas deserve particular attention because Portugal handles them differently from its neighbours.
Restaurants: no dine-in versus takeaway split
Most EU states draw a line between a meal consumed on the premises and the same food sold to take away. Portugal deliberately does not. A meal supplied by a restaurant or catering business is taxed at the intermediate 13% rate whether it is eaten at the table, collected from the counter or delivered to a doorstep. What is carved out is drink: alcohol, soft drinks, juices, nectars and carbonated or added-gas waters all stay at 23%. So a typical Portuguese restaurant bill carries two rates, and the software has to split them.
There is one important exception. An establishment that is exclusively takeaway — no tables, no table service — is treated as a food retailer rather than a restaurant, and charges 23%. And where an invoice mixes rates it must show the taxable base for each of them separately; if it does not, the highest rate appearing on the document applies to the whole amount. That rule turns a lazy invoice layout into a ten-point tax increase.
Electricity: two rates on one bill
Since Lei n.º 38/2024 took effect on 1 January 2025, the reduced 6% rate applies to the first 200 kWh consumed in each 30-day period on domestic contracts with a contracted power of up to 6.9 kVA — rising to 300 kWh for households of five or more. Everything above that band is taxed at 23%. Low-pressure natural gas gets comparable treatment up to 12,000 m³ a year. A single Portuguese electricity bill therefore routinely shows both 6% and 23% lines, which is worth remembering before you try to reverse a household energy total with one rate.
The 2026 State Budget added a handful of targeted moves: olive oil production activities dropped from 23% to 6% on the mainland (and to 4% in Madeira and the Azores) from 1 January 2026, the IVA exemptions covering agricultural inputs such as fertilisers, seed and animal feed were extended to 31 December 2026, and group-level IVA balance consolidation arrives on 1 July 2026.
Registration and the €15,000 line
Portugal separates registration from charging. Every business files a declaração de início de atividade with the Autoridade Tributária before its first supply, but whether it then adds IVA to invoices depends on Artigo 53.º CIVA. A business whose turnover in Portugal in the previous calendar year did not exceed €15,000 is exempt: it invoices without IVA, files no periodic return, and cannot deduct the IVA on its own purchases. Every invoice must carry the wording "IVA – regime de isenção (artigo 53.º do CIVA)".
The threshold climbed in annual steps — €12,500, then €13,500, then €14,500 — and settled at €15,000 for 2025, where it remains for 2026. Exceed it by more than 25% during the year, meaning you pass €18,750, and you leave the regime immediately: the invoice that breaks the limit already carries IVA, and you have 15 business days to tell the AT. Since July 2025 keeping organised accounts no longer bars access to the regime, and importing goods no longer disqualifies you either. Non-established businesses have no threshold at all and register from the first taxable supply in Portugal; those established outside the EU must additionally appoint a Portuguese-resident fiscal representative who is themselves a Portuguese VAT taxable person.
The Portuguese filing rhythm
Frequency is set by prior-year turnover, and the deadlines are unusually long by EU standards:
- Monthly — prior-year turnover of €650,000 or more. The return is due by the 20th of the second month after the period, so January's return is filed on 20 March.
- Quarterly — prior-year turnover below €650,000. Due by the 20th of the second month after the quarter, so January–March is filed on 20 May.
- Payment — by the 25th of the same month in which the return falls due.
- SAF-T (PT) billing file — a separate, monthly obligation, due by the 5th of the following month regardless of your return frequency.
Businesses under the monthly threshold may opt in to monthly filing, which is worth doing if you are habitually in a repayment position. Intra-EU recapitulative statements are filed separately, and the annual IES carries the VAT annexes.
Cash accounting deserves a mention because the numbers changed recently and materially. Decreto-Lei n.º 34/2025 raised the entry threshold for the regime de IVA de caixa from €500,000 to €2,000,000 of turnover with effect from 1 July 2025. Under it, IVA becomes chargeable when you are actually paid — or at the latest in the twelfth month after the invoice date — and input IVA is deducted only once you have paid your supplier. The option is exercised in October for effect the following January, carries a minimum stay of two years, and requires invoices to be issued in a dedicated series bearing the words "IVA – regime de caixa".
ATCUD, QR codes and certified software
Portugal built its invoice-fiscalisation regime a decade before most of Europe, and an invoice here is not merely a document — it is a record the tax authority expects to reconstruct independently. Four layers stack up:
- Certified billing software — mandatory above €50,000 of annual turnover, and also for smaller businesses issuing more than 1,000 invoices a year. It must print its AT certification number and chain each document to the previous one so gaps and back-dating are detectable.
- QR code — on every invoice since 1 January 2022, encoding both parties' NIFs, the document type and number, the taxable base and tax per rate, and the ATCUD.
- ATCUD — since 1 January 2023, a unique document code in the form
ValidationCode-SequentialNumber. The validation code is requested from the AT in advance for each document series. No registered series, no valid invoice. - SAF-T (PT) billing file — the standardised XML export of every document issued, submitted monthly by the 5th, which is what lets the AT pre-populate the consumer e-fatura portal and reconcile your return against your actual invoices.
Three 2026 dates matter. From 1 January 2026, B2G e-invoicing in the CIUS-PT format — mandatory for large suppliers to the public sector since 2021 — extends to micro, small and medium-sized enterprises. Through 31 December 2026, a PDF invoice issued by certified software with a valid ATCUD and QR code is still accepted as an electronic invoice without a qualified electronic signature; the QES requirement, deferred again by the 2026 State Budget, now bites on 1 January 2027. And the first mandatory submission of the accounting SAF-T file has slipped to 2028, for 2027 data — the billing SAF-T is unaffected.
Portuguese IVA calculation formulas
The arithmetic is the same in all three territories; only the rate changes. Take the mainland standard rate of 23%:
Add 23% IVA (net to gross)
Formula: Gross = Net × (1 + IVA Rate)
IVA Amount = €100.00 × 0.23 = €23.00
Gross Price = €100.00 + €23.00 = €123.00
Remove 23% IVA (gross to net)
Formula: Net = Gross ÷ (1 + IVA Rate)
Net Price = €123.00 ÷ 1.23 = €100.00
IVA Portion = €123.00 − €100.00 = €23.00
The divisors for every Portuguese rate
To strip IVA out of a gross price, divide by the figure below for the territory the operation belongs to.
| Territory | Standard | Intermediate | Reduced |
|---|
| Mainland | ÷ 1.23 | ÷ 1.13 | ÷ 1.06 |
| Madeira | ÷ 1.22 | ÷ 1.12 | ÷ 1.04 |
| Azores | ÷ 1.16 | ÷ 1.09 | ÷ 1.04 |
Azores example: €116.00 ÷ 1.16 = €100.00 net, so €16.00 is IVA
Madeira example: €122.00 ÷ 1.22 = €100.00 net, so €22.00 is IVA
