Foreign companies operating in Portugal must navigate VAT (IVA) registration, reverse-charge mechanics, the EU OSS regime, mandatory e-invoicing via certified software, monthly SAF-T file submission, and (for non-EU companies) fiscal representation. Standard VAT rate is 23% mainland (22% Madeira, 16% Azores). Most B2B services use reverse-charge — no Portuguese VAT registration needed. Selling B2C digital services to EU consumers above EUR 10k cross-border? OSS is mandatory. Holding stock in Portugal for fulfilment? Direct VAT registration required.

When does a foreign company need to register for Portuguese VAT?

Five common triggers:

1. Goods physically supplied in Portugal — e.g., a UK company selling goods stored in a Portuguese warehouse
2. B2C digital services above the OSS threshold (EUR 10,000 cross-border per year) — though OSS itself replaces direct registration in each member state
3. Permanent establishment in Portugal — office, warehouse, sales force; this also triggers IRC corporate tax obligations
4. Stock held in Portugal for fulfilment (Amazon FBA, e-commerce 3PL) — even without permanent establishment, this triggers VAT registration
5. Intra-EU acquisitions above EUR 10,000 — buying goods from other EU member states for use in Portugal above the threshold

What does NOT typically trigger registration: pure B2B services billed to Portuguese companies (reverse-charge applies; customer self-accounts).

Portuguese VAT rates 2026

Examples of items at each rate:

• 23% standard: most goods and services, professional services, software, hardware, fashion
• 13% intermediate: restaurants and cafés, certain food products, some agricultural inputs
• 6% reduced: essential foods (bread, milk), books, newspapers, medicines, hotel accommodation, public transport
• 0% / exempt: certain medical services, education, financial services, exports outside EU, intra-EU B2B supplies

Reverse-charge — the most common scenario for foreign companies

Reverse-charge (autoliquidação) shifts VAT obligation from supplier to customer. Three common cases:

1. B2B services between EU companies

Foreign EU company invoices Portuguese business with no VAT, noting "VAT reverse-charge — Article 196 of Directive 2006/112/EC". Portuguese customer self-accounts for 23% VAT on its periodic VAT return (right to deduct in the same return — net VAT impact zero for fully-taxable customers).

2. Services from non-EU to Portuguese business

US, UK, BR company invoices Portuguese business with no VAT. Portuguese customer applies reverse-charge at 23% on its return.

3. Supply of construction services in Portugal

Specific Portuguese reverse-charge regime for construction services where the customer is a VAT-registered business — even if both parties are Portuguese. Common in real estate development.

OSS — One-Stop Shop for EU B2C

OSS replaces the old MOSS (Mini One-Stop Shop) and covers:

• Cross-border B2C digital services (software, downloads, streaming, e-learning)
• Distance sales of goods within EU (e-commerce shipped from one EU country to consumers in another)
• B2C services with deemed location at customer in another EU country

How it works:

• Below EUR 10,000 cross-border B2C turnover per year: charge supplier-country VAT to all EU consumers
• Above EUR 10,000: register for OSS in one EU country (typically your country of establishment), then charge each customer's country VAT rate
• File ONE quarterly OSS return covering all EU sales
• Pay total VAT to the OSS country tax authority, which redistributes to other member states
• No need to register in each individual EU member state

Fiscal representation for foreign VAT registrants

If a foreign company directly registers for Portuguese VAT (e.g., for warehouse stock or B2C goods supply):

• EU-established companies: can register directly without fiscal representative (mutual assistance treaties apply)
• Non-EU companies: must appoint a fiscal representative in Portugal who is jointly liable for VAT obligations
• UK companies post-Brexit: now classified as non-EU — fiscal representation required for direct VAT registration in Portugal
• Cost of fiscal representation: typically EUR 200-500/year plus a security deposit equivalent to 1-3 months of estimated VAT

HVR coordinates fiscal representation with specialised partners (we don't provide it directly).

E-invoicing and SAF-T — mandatory for VAT-registered companies

Certified invoicing software

All companies registered for Portuguese VAT must issue invoices via AT-certified software. Each invoice must include:

• QR code with invoice metadata (mandatory since 2022)
• ATCUD code — unique invoice identifier issued by AT
• Buyer's NIF if Portuguese, EU VAT ID if EU B2B, full company info if non-EU
• VAT breakdown by rate
• Reverse-charge or exemption legal references where applicable

Common certified software: Moloni, Sage, PHC, FacturaPlus, Vendus, InvoiceXpress, MasterData. Foreign companies must configure their chosen software with Portuguese settings (NIF, VAT regime, document series).

SAF-T monthly file

By the 5th of each month, submit the SAF-T (Standard Audit File for Tax) file for the previous month, containing:

• All invoices issued (sales)
• All invoices received and accounted (purchases — for organised accounting)
• Document series, voids, credit notes
• VAT codes used and exemption justifications

SAF-T is generated automatically by certified software and submitted via Portal das Finanças. Penalty for missing submission: EUR 200-2,500 per month.

Common mistakes foreign companies make

• ❌ Charging Portuguese VAT to a foreign B2B customer who should reverse-charge — creates fictitious Portuguese VAT liability
• ❌ Not registering when Amazon FBA stock arrives in Portuguese warehouse — triggers retrospective VAT + penalties
• ❌ Using non-certified invoicing software — invoices invalid for Portuguese VAT deduction
• ❌ Missing SAF-T monthly submission — penalty per missed file
• ❌ Treating Madeira / Azores as same VAT rate as mainland
• ❌ Confusing OSS with IOSS (Import One-Stop Shop, which is for low-value imports from outside EU)
• ❌ UK companies assuming they don't need fiscal rep (post-Brexit they do for direct VAT registration)

VAT registration process for foreign companies

1. Obtain Portuguese tax number (NIF) for the foreign company
2. For non-EU: appoint fiscal representative
3. File "Declaração de Início de Atividade" at Portal das Finanças choosing the correct VAT regime
4. Configure certified invoicing software with Portuguese settings
5. Set up monthly or quarterly VAT return submission process
6. Set up monthly SAF-T submission
