Whether you are an individual citizen or a multinational entity, navigating the **Register Number (RD)** and the **State Registration Number (UBD)** is the only way to operate within the General Department of Taxation’s (GDT) real-time environment.

## Frequently asked questions

### 1. What is a TIN in Mongolia?

In Mongolia, there is no single label for a "TIN." Instead, the system uses the **Register Number** (_Registeriin dugaar_) as the primary identifier for tax and administrative purposes.

- **For Individuals:** It is the 10-character personal ID.
- **For Businesses:** It is a unique 7-digit numeric code assigned upon incorporation by the State Registration Office.

### 2. What types of identifiers exist?

Mongolia uses a multi-layered system to distinguish between citizens, foreign residents, and legal entities:

- **Individual Register Number (RD):** A 10-character alphanumeric identifier for citizens.
- **F-Register (F-Бүртгэл):** A unique **13-digit numeric ID** issued to foreign nationals with residence permits.
- **State Registration Number (UBD):** The **7-digit numeric code** that serves as the legal "birth certificate" for businesses.
- **Civil Registration Number:** A **12-digit numeric code** used internally by the civil registry for biometric data management.

### 3. What is the format of the TIN (RD) and UBD?

Mongolian identifiers follow strict algorithmic patterns designed for the **E-Tax** and **E-barimt** portals.

- **The NEWRD (Individual RD) Structure:** Exactly **10 characters** consisting of **2 Cyrillic letters followed by 8 digits** (e.g., `АБ12345678`).

  - The letters represent the province and district of birth.
  - The digits represent the date of birth and a serial number.
- **The Business UBD (Register Number):** Exactly **7 numeric digits** (e.g., `1234567`).

**Technical Insight:** In 2026, the **E-barimt** system uses the **7-digit UBD** to verify every B2B transaction. If a business enters an incorrect Register Number on an electronic receipt, the 2% VAT refund (or lottery entry for individuals) is automatically invalidated by the system, often leading to immediate payment disputes.

### 4. Which authority issues the TIN?

The [General Authority for State Registration (GASR)](https://burtgel.gov.mn/) is the primary body that issues the RD for individuals and the UBD for businesses.

Tax-specific activation and the issuance of the Taxpayer Certificate are handled by the [General Department of Taxation (GDT)](https://mta.gov.mn/). For foreign residents, the **Immigration Agency of Mongolia** issues the **F-Register** during the residence permit process.

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

**Registration Thresholds & Mandates:**

- **Mandatory VAT Registration:** Any entity or individual whose annual sales income exceeds **MNT 50 million** (approx. $14,500) must register as a VAT payer.
- **Voluntary Registration:** Possible for businesses with turnover between MNT 10 million and 50 million.
- **Progressive CIT (2026):** Mongolia’s 2026 tax reform maintains a **10% Corporate Income Tax (CIT)** for profits up to MNT 6 billion, with a higher **25% rate** for profits exceeding that threshold.
- **Non-Residents:** Must register and obtain a TIN if they have a Permanent Establishment or provide digital services to Mongolian consumers.

**Tax Rates (2026):**

- **Standard VAT:** 10%.
- **Individual Income Tax (PIT):** Progressive rates of 10%, 15%, and 20% (with a tax-free threshold for low earners).

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

The process is highly integrated through the **E-Mongolia** digital platform.

- **Step 1: GASR Registration:** New businesses register with the State Registration Office to receive their **7-digit UBD**.
- **Step 2: GDT Activation:** Apply for taxpayer status at the District Tax Office or via the **E-Tax portal**.
- **Step 3: E-barimt Setup:** Once the TIN is active, you must register your business on the **E-barimt** system to issue fiscalized receipts.
- **Step 4: F-Register (Foreigners):** Foreign individuals obtain their 13-digit ID upon receiving a work or residence visa from the Immigration Agency.

### 7. How to verify a Mongolian Tax ID (Register Number)?

In the 2026 digital economy, verifying a partner's RD or UBD is essential for VAT refund eligibility.

- **Official Search:** The GDT provides a [Taxpayer Search Tool](https://e-tax.mta.mn/) where you can verify if a Register Number is an "Active VAT Payer."
- **GASR Verification:** Use the **Burtgel.mn** portal to verify the legal existence of a company via its UBD.
- **TaxDo Automation:** Manual checks on Cyrillic-based portals are slow and error-prone. TaxDo’s **GTL** service provides real-time API verification against official Mongolian data sources to ensure a Register Number is valid and active.

- **Customs Gridlock:** Goods will be held at the Zamiin-Uud or Altanbulag border crossings if the Register Number on the manifest does not match the GDT database.
- **E-Mongolia Block:** Without a verified Register Number, you cannot access government services, renew licenses, or submit tenders.
