Liechtenstein Tax ID Number (TIN) Guide

In Liechtenstein, the Tax Identification Number (TIN) is referred to as the PEID Nummer (Personenidentifikationsnummer). This unique identifier is essential for individuals and entities to comply with tax regulations, including income tax filings, VAT registration, and other official processes. All information provided in this guide is verified from official sources, ensuring accuracy and reliability.​

Tax Identification Number Types

Liechtenstein utilizes the PEID Nummer as the sole TIN for both individuals and entities. There is no separate TIN for businesses or legal entities; the PEID Nummer serves all purposes.​

TIN Format and Structure

  • Format: The PEID Nummer consists of 4 to 12 digits, all numeric.​
  • Structure: The number is a continuous string without any separators or country code.​
  • Example: 123456789012

Note: The number may appear shorter if leading zeros are omitted. ​

Issuing Authority and Registration Process

  • Issuing Authority: The PEID Nummer is issued by the Liechtenstein Office of Statistics (Amt für Statistik).​
  • Registration Process:
    1. Eligibility: Individuals and entities must be registered in Liechtenstein.​
    2. Documents Required:
      • Valid identification (e.g., passport or national ID).
      • Proof of residence or business registration.
    3. Application Method: Applications are processed electronically.​
    4. Fees: Specific fees may apply; refer to the official website for details.​
    5. Processing Time: Typically, registration is completed within a few business days.​
