Nestled between Switzerland and Austria, Liechtenstein is a global powerhouse for wealth management and high-tech industry. Operating in the Principality requires navigating a unique fiscal intersection: it is a member of the EEA but maintains a Customs and VAT Union with Switzerland. In 2026, the big story is the full enforcement of eVAT mandatory filing and the adoption of the GloBE (Pillar Two) minimum tax amendments. Understanding the PEID, UID, and VAT identifiers is the only way to maintain compliance in this highly transparent, “digital-first” tax environment.

10 Essential Questions About TIN in Liechtenstein
Common Questions
1. What is a TIN in Liechtenstein?
Liechtenstein does not use a single "TIN" label. Instead, it utilizes two distinct identifiers based on the taxpayer's legal status:
-
For Individuals (Natural Persons): The primary identifier is the PEID (Personenidentifikationsnummer), a unique 5-digit code used for personal income tax and social security.
-
For Businesses (Legal Entities): The identifier is the UID (Unternehmens-Identifikationsnummer). This is the universal "Enterprise ID" used for corporate tax and commercial registration.
Due to the VAT Union with Switzerland, the business UID also serves as the base for the VAT number (using the CHE prefix).
