If you’ve moved to Portugal or become tax resident there, one of the most common questions is: “Do I have to declare my assets abroad?” The answer is yes — but it’s important to understand what that really means.

Key Requirement:

Under Portuguese law, residents must file the “Modelo 10 – Declaração de Início de Atividade e Identificação de Contas e Aplicações no Estrangeiro.”

This is an informational declaration, not a tax return. It notifies the Portuguese Tax Authority (AT) that you hold foreign accounts or investments.

What It Covers:

• 
  
• 
  
• Foreign bank and brokerage accounts
• 
  
• 
  
• 
  
• Overseas investment portfolios
• 
  
• 
  
• 
  
• Life insurance and other financial products held abroad
• 
  
• 
  

You’re not taxed on the asset values themselves. Reporting is informational — taxation only occurs when:

• 
  
• 
  
• You earn income from those assets (interest, dividends, or capital gains), or
• 
  
• 
  
• 
  
• You own high-value property that triggers the AIMI wealth tax.
• 
  
• 
  

This filing is key for compliance and transparency. Failing to declare can lead to administrative penalties or trigger audits, even if no tax is due.

Key Takeaway:

Declaring your foreign assets to Portugal doesn’t mean paying more tax — it means staying compliant and avoiding future issues.
