Portugal Reverse Charge VAT (Autoliquidação): The 2026 Guide

If you do business in or with Portugal, you will sooner or later meet the word autoliquidação — Portugal's name for the reverse charge mechanism. Instead of the supplier charging IVA (Portugal's VAT) on the invoice, the buyer accounts for the tax themselves. Get this wrong and you either overcharge your client or file an invalid invoice. This guide explains exactly when autoliquidação applies in Portugal in 2026, what your invoice must say, and what each side has to declare.

What "autoliquidação" actually means

Under normal IVA rules, the seller adds IVA to the invoice, collects it, and pays it to the tax authority (Autoridade Tributária, AT). Under autoliquidação (self-assessment), the invoice is issued without IVA, and the buyer calculates the tax at the applicable Portuguese rate and reports it on their own IVA return. The mechanism exists mainly for cross-border B2B trade inside the EU and for a few domestic sectors prone to fraud, such as construction.

The legal backbone is the Código do IVA (CIVA) — Portugal's VAT code — together with the EU VAT Directive. The key provisions are Article 6 (place of supply) and Article 2(1)(j) (domestic reverse charge in construction).

When reverse charge applies in Portugal

1. Services to business customers in other EU countries

Article 6(6)(a) CIVA sets the general B2B place-of-supply rule: when the customer is a VAT-registered business (sujeito passivo), the service is taxed in the customer's member state. So if your Portuguese company invoices a VAT-registered client in Germany, you do not charge Portuguese IVA. The German client self-assesses German VAT under reverse charge.

Conditions: the client must have a valid EU VAT number (check it in VIES), and your invoice must carry the reverse-charge mention (see below). You still have reporting duties: the sale goes on your Declaração Recapitulativa (the EU recapitulative statement).

2. Services received from suppliers in other EU countries

The mirror image: when your Portuguese business buys services from a VAT-registered supplier in another EU country, you are the one who self-assesses. You calculate Portuguese IVA at the applicable rate on the invoice value and report it in your DPIVA (periodic IVA return) — the taxable base in field 12 and the tax in field 13 of table 06. If you have full deduction rights, you deduct the same amount (fields 20–23), so the operation is cash-neutral. Without deduction rights, it becomes a real cost — a trap for exempt businesses and freelancers under Article 53.

3. Intra-EU acquisitions of goods

Goods shipped from another EU country to a Portuguese VAT-registered buyer follow the destination principle: the foreign supplier invoices without VAT (marked "reverse charge"), and the Portuguese buyer self-assesses Portuguese IVA via the DPIVA. Your VAT number must be registered in VIES for intra-EU acquisitions.

4. Domestic construction services (inversão do sujeito passivo)

Portugal also applies reverse charge domestically in the construction sector under Article 2(1)(j) CIVA: when construction, renovation, repair, maintenance or demolition services are supplied to a Portuguese VAT-registered customer with full or partial deduction rights, the customer accounts for the IVA, not the contractor.

Important change since 1 July 2026: the tax authority's circular OC 25117/2026 now requires the service provider to hold an IMPIC contractor licence (alvará or certificado) for the reverse charge to apply. Without it, the provider must charge normal IVA even if the work is factually construction. If you are a subcontractor without an IMPIC licence, do not issue "IVA — autoliquidação" invoices.

Portuguese IVA rates you need in 2026

When the buyer self-assesses, they use the rate that would apply to a domestic sale of the same goods or services:

• Mainland Portugal: 23% (standard), 13% (intermediate), 6% (reduced)
• Madeira: 22% / 12% / 5%
• Azores: 18% / 9% / 4%

Most B2B services fall under the standard rate, but reduced rates apply to items like food, books, hotel accommodation and certain cultural services — worth checking per transaction.

What your invoice must contain

A reverse-charge invoice in Portugal must include:

• Both parties' full names, addresses and VAT numbers (the customer's VAT number is mandatory)
• The explicit mention "IVA — autoliquidação"
• Net amounts with no IVA added — never write "IVA 0%" as if it were a rate; the correct concept is that the customer accounts for the tax
• Sequential invoice number, issue date, and a clear description of the goods or services

Missing the "IVA — autoliquidação" mention is one of the most common audit findings. The AT treats it as a formal invoicing obligation, and penalties apply even when the tax itself was correctly self-assessed.

Common mistakes to avoid

• Applying reverse charge to consumers. The B2C rule (Art. 6(6)(b) CIVA) taxes the supply in the supplier's country — a Portuguese business selling to a French consumer charges Portuguese IVA. Reverse charge is B2B only.
• Skipping the VIES check. If the customer's VAT number is invalid, the supply is not an intra-EU transaction — you must charge Portuguese IVA.
• Forgetting the Declaração Recapitulativa. Intra-EU supplies of goods and services must be reported there, in addition to the DPIVA.
• Exempt buyers self-assessing nothing. A business under the Article 53 exemption that receives intra-EU services must still self-assess — and because it cannot deduct, the IVA is a real cost. Many small freelancers learn this the hard way with Irish-platform commissions (e.g. booking or advertising platforms).
• Construction without IMPIC licence. Since July 2026, issuing autoliquidação construction invoices without the licence is no longer covered — charge 23% instead.

Frequently asked questions

Do I need to register for IVA to use reverse charge as a buyer?

Yes. To self-assess IVA on intra-EU acquisitions or services, you must be a VAT-registered sujeito passivo in Portugal with a VIES-validated number. Businesses under the Article 53 exemption can register specifically to self-assess without fully entering the normal regime, but they should check the current procedure with the AT or an accountant.

Does reverse charge apply to sales outside the EU?

Exports of goods and most services to non-EU customers are generally exempt (not reverse charge) — for example under Articles 14 and 21 CIVA. The invoice should reference the exemption rather than autoliquidação.

What is the difference between autoliquidação and isenção?

Autoliquidação means the tax is still due, but the buyer accounts for it. Isenção (exemption) means no tax is due at all, though it may limit the right to deduct input IVA. They are different legal concepts with different invoice mentions.

Can I deduct the IVA I self-assess?

If you carry out operations that give full or partial deduction rights, yes — the self-assessed IVA is reported and deducted in the same DPIVA, making it cash-neutral. Businesses with exempt activity or under Article 53 generally cannot deduct it.

Which DPIVA fields are used for reverse-charge purchases?

For intra-EU acquisitions of goods: taxable base in field 12 and the self-assessed tax in field 13 of table 06, with the corresponding deduction in field 20 (fixed assets) or fields 21–23. Keep your accounting software's mapping up to date, as field layouts can change.
