Understanding VAT in Portugal

VAT in Portugal (Imposto sobre o Valor Acrescentado, IVA) is governed by the Portuguese VAT Code in line with EU Directive 2006/112/EC. The standard rate is 23%, with reduced rates of 13% and 6% applicable to specific goods and services.

Businesses registered for VAT charge tax on their supplies (output VAT) and can deduct input VAT paid on purchases that support taxable activities. When input VAT exceeds output VAT, a refund may be claimed or the balance carried forward. The refund process is supervised by the Autoridade Tributária e Aduaneira (AT), accessible via the Portal das Finanças.

VAT returns and refund applications are submitted electronically, with documentation and invoice verification conducted by the AT before payments are approved.

Who Can Claim a VAT Refund?

Eligibility for VAT refunds depends on a company’s registration status and business activity in Portugal.

Domestic (Portuguese-registered) businesses

VAT-registered entities may reclaim input VAT on purchases used exclusively for taxable operations. Refund claims are made through periodic VAT returns filed via the Portal das Finanças. The taxpayer must maintain complete and valid documentation demonstrating the business purpose of each expense.

EU-based foreign businesses

Companies established in another EU Member State can reclaim Portuguese VAT under Council Directive 2008/9/EC, provided they are not VAT-registered or established in Portugal. Applications are submitted through the claimant’s home-country VAT refund portal, which forwards the request to the AT for processing.

Non-EU businesses

Companies outside the EU can claim VAT refunds under the 13th Directive (86/560/EEC), provided there is a reciprocity agreement between Portugal and their home country. Applications must be submitted directly to the AT with supporting documentation and a certificate of taxable status.

Exporters and cross-border service providers

Exporters and businesses providing international services may recover input VAT on goods and services directly tied to zero-rated or cross-border transactions, provided that all invoices and declarations align with Portuguese VAT requirements.

When Can Portugal Businesses Claim a VAT Refund?

VAT refund timelines in Portugal differ for domestic taxpayers and overseas entities. Understanding these filing windows ensures compliance and prevents forfeiture of refund rights.

Domestic VAT refund timing

In Portugal, VAT-registered businesses file periodic VAT returns either monthly (typically for those with larger VAT liabilities) or quarterly (for those under the threshold, often €650,000). Returns must be submitted by the 20th day of the second month following the relevant period. Refunds for excess input VAT may be carried forward or refunded

EU-based foreign claimants

EU claimants must file refund applications by 30 September of the year following the refund period. The Portuguese tax authority (Autoridade Tributária e Aduaneira, AT) guidance indicates that for claims covering 12 consecutive months, the claim amount must exceed EUR 250; otherwise, in cases with shorter periods, the overall claim may need to exceed EUR 3,000.

Non-EU claimants

For businesses based outside the EU applying under the 13th Directive (86/560/EEC), the same minimum thresholds apply: claims covering 12 consecutive months must exceed EUR 250, and in other cases may need to exceed EUR 3,000, as per AT’s published guidance. Eligibility is further subject to reciprocity and correct documentation.

What Can You Claim?

Only VAT incurred on legitimate business expenses directly linked to taxable activities can be recovered. All claims must be backed by invoices compliant with Portuguese VAT rules.

Typical refundable expenses include:

  • Rent, utilities, and professional services related to business operations.
  • Travel, hotel accommodation, and car hire for business purposes.
  • Trade fairs, exhibitions, and marketing expenses.
  • Purchase or import of equipment used in taxable activities.
  • Import VAT paid to Portuguese customs authorities.

Invoices must show the supplier’s VAT number, buyer identification, date, taxable base, VAT rate, and amount.

What Expenses Are NOT Eligible for a VAT Refund in Portugal?

The Portuguese VAT Code restricts refunds for certain categories of expenses to prevent personal or non-business use.

Non-refundable or partially deductible items include:

  • Entertainment, meals, and hospitality expenses.
  • Passenger vehicles not used exclusively for business.
  • Employee benefits and gifts.
  • Mixed-use purchases without a clear business allocation.
  • Costs associated with VAT-exempt activities such as financial services, healthcare, or education.
  • Invoices that do not meet AT’s format or data standards.

Errors in invoice data or missing details such as VAT numbers or payment references frequently cause delays or rejections.

Are Non-Portugal Businesses Eligible for a VAT Refund?

Foreign businesses can recover Portuguese VAT if they meet EU or 13th Directive conditions.

EU-based claimants

Refund applications are filed electronically via the claimant’s home tax authority under Directive 2008/9/EC. The home authority transmits the claim to Portugal’s AT, which conducts the review and payment. Communication occurs through the same online system.

Non-EU claimants

Applications must be submitted directly to the:
Autoridade Tributária e Aduaneira (AT)
Direção de Serviços do IVA: Reembolsos a Sujeitos Passivos não Estabelecidos
Lisbon, Portugal.
The application must include:

  • Original invoices or import documentation.
  • A certificate of taxable status issued by the applicant’s home tax authority.
  • Proof of payment and valid bank details for refund transfer.

Refunds are processed once the AT verifies reciprocity between Portugal and the applicant’s jurisdiction. Payments are made in euros to the bank account listed in the application.

Step-by-Step: Reclaiming VAT for Portuguese Businesses

For domestic taxpayers, the VAT refund process is integrated into regular VAT compliance.

  1. Verify VAT registration: Ensure an active VAT ID and compliance with return filing requirements.
  2. Confirm deductible invoices: Only expenses supporting taxable activities qualify.

Step-by-Step: Reclaiming VAT for Overseas Businesses

Foreign claimants must follow the appropriate EU or non-EU procedure.

  1. Determine eligibility: No fixed establishment or Portuguese VAT registration.
  2. Choose the correct filing route:
    • EU businesses: Apply via the home-country VAT portal under Directive 2008/9/EC.
    • Non-EU businesses: Apply directly to AT under Directive 86/560/EEC.
  3. Prepare documents: Original invoices, certificate of taxable status, and proof of payment.
  4. Submit before deadlines:
    • 30 September for EU claimants.
    • 30 June for non-EU claimants.
  5. Monitor requests: Respond promptly to AT’s additional information queries.
  6. Receive payment in euros to the account listed in the claim once approved.

Refund processing typically takes up to four months, extending to eight if supplementary documents are required.

Documentation and Compliance Checklist

Successful VAT recovery in Portugal depends on maintaining complete, verifiable documentation that supports every line of a refund claim. The Portuguese Tax Authority (Autoridade Tributária e Aduaneira, or AT) requires precise, audit-ready records that confirm each transaction’s link to business activities. Proper documentation not only accelerates processing but also protects companies during post-refund reviews or audits.

Portuguese VAT law requires that all financial records, invoices, and declarations be stored for at least 10 years, either in secure digital archives or physical form. Maintaining consistent formatting, backup copies, and timestamped digital invoices helps ensure audit-readiness and compliance with evolving e-invoicing requirements.

How to Stay VAT-Compliant With Your Paperwork

Compliance in Portugal extends beyond filing deadlines; it requires maintaining accurate digital records, using certified invoicing systems, and adhering to AT’s audit and data retention standards. A structured approach ensures not only refund approval but also long-term credibility with tax authorities.

To maintain strong VAT governance:

  • Retain all VAT invoices and returns in digital format, preferably with electronic time-stamps.
  • Verify supplier VAT numbers through the VIES (VAT Information Exchange System) before submitting claims.
  • Translate documents into Portuguese or English if issued in other languages to prevent verification delays.
  • File refund claims and VAT returns only via authorized tax platforms such as Portal das Finanças or your home-country EU refund portal.
