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.  
Navigating a jurisdiction with more registered companies than citizens requires high-precision data. This FAQ guide provides grounded insights into Liechtenstein’s identification ecosystem, updated for the 2026 regulatory landscape.

## Frequently asked 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).

### 2. What types of identifiers exist?

Liechtenstein utilizes a structured set of IDs to manage its commercial registry and tax union:

- **PEID (Person ID):** 5-digit for natural persons and residents.
- **UID (Enterprise ID):** CHE-prefixed number for legal entities (aligned with Swiss UID).
- **VAT Number (MWST):** The UID with "CHE" prefix for VAT purposes (e.g., CHE-123.456.789 MWST).
- **CRN (Commercial Register Number):** Issued by Office of Justice for company formation.

### 3. What is the format of the TIN (PEID) and UID?

Liechtenstein identifiers follow strict numeric patterns, often integrated with Swiss validation logic.

- **PEID Structure:** Exactly 5 numeric digits (e.g., 12345).
- **UID / VAT Format:** CHE- followed by 3 groups of 3 digits and checksum (e.g., CHE-123.456.789 MWST).

**Technical Insight:** Liechtenstein uses the Swiss **CHE** format for its VAT union. These numbers utilize the **"11-test" (Elfproef)** checksum. In 2026, the **eVAT portal** uses this logic to validate identities; any mismatch in a CHE-prefixed ID will block the filing, as the system is integrated with the Swiss-Liechtenstein common master file.

### 4. Which authority issues the TIN?

The [Liechtenstein Office of Statistics (Amt für Statistik)](https://www.llv.li/de/landesverwaltung/amt-fuer-statistik) is the primary body responsible for issuing the PEID.

The [Tax Administration (Steuerverwaltung)](https://www.llv.li/de/landesverwaltung/steuerverwaltung) manages VAT registration and the mandatory **eVAT** portal. For company formation and CRN issuance, the **Office of Justice (Amt für Justiz)** is the central registrar.

### 5. Who needs to register for a TIN and VAT? (2026 Update)

**Registration Thresholds & Mandates:**

- **Mandatory VAT Registration:** Any entity with an annual worldwide turnover exceeding **CHF 100,000** must register for VAT in Liechtenstein.
- **GloBE (Pillar Two) Mandate:** As of 2026, large multinational groups with a presence in Liechtenstein must register on the **Tax Administration's electronic portal** to comply with the 15% global minimum tax reporting (GIR).
- **Mandatory eVAT (2025/2026):** All VAT-liable entities must use the **eVAT (e-MWST)** portal for filing. Paper submissions are no longer accepted.
- **Non-Residents:** Foreign companies providing services in Liechtenstein must register if their _global_ turnover exceeds CHF 100,000, even if local turnover is low.

**Tax Rates (2026):**

- **Standard VAT:** 8.1% (Aligned with Switzerland).
- **Corporate Income Tax:** 12.5% (A minimum tax of CHF 1,800 applies).

### 6. How to register for a TIN in Liechtenstein?

Registration is highly digitized and integrated with the commercial register.

- **Step 1: Office of Justice:** Form your legal entity (AG, GmbH, or Foundation) to receive your **CRN** and **UID**.
- **Step 2: PEID Assignment:** The Office of Statistics automatically generates the PEID upon registration of the entity or individual.
- **Step 3: eVAT Registration:** If you cross the CHF 100,000 threshold, apply for VAT status via the [eVAT portal](https://www.llv.li/de/landesverwaltung/steuerverwaltung/mehrwertsteuer/e-mwst).
- **Step 4: Activation:** Authenticate your identity through the national **eID.li** system to access all government digital services.

### 7. How to verify a Liechtenstein Tax ID?

Verification is critical in 2026 to ensure your partners are not "shell" entities and are active in the common VAT area.

- **Official Registry:** Use the [Liechtenstein Business Register (Firmenindex)](https://www.oera.li/) to verify the status of a CRN or UID.
- **VAT Verification:** While Liechtenstein is not in VIES, its VAT numbers can be verified via the [Swiss/Liechtenstein UID Register](https://www.uid.admin.ch/).
- **TaxDo Automation:** Manual checks across multiple registries are inefficient. TaxDo’s **GTL** service provides real-time API verification to confirm if a Liechtenstein Business VAT ID is active and valid.
