Colombia’s fiscal landscape in **2026** is defined by the **DIAN’s (Dirección de Impuestos y Aduanas Nacionales)** aggressive “Extraordinary Fiscal Package.” Following the adoption of the emergency tax measures to fund the 2026 national budget, the oversight on the **NIT (Número de Identificación Tributaria)** has reached unprecedented levels. The most critical change this year is the introduction of the **IPUSUI** (Tax on Single-Use Plastic Products) and the activation of the **RADIAN** system’s mandatory registration for all electronic invoices qualifying as negotiable instruments. In this high-stakes environment, your 10-digit NIT (including the verification digit) is the mandatory anchor for compliance.

## Frequently asked questions

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

In Colombia, the Taxpayer Identification Number is known as the **NIT (Número de Identificación Tributaria)**.

- **For Businesses:** It is the mandatory identifier for all legal entities, branches, and permanent establishments.
- **For Individuals:** It is used by residents and non-residents who have tax obligations, such as income tax filers or VAT-responsible agents.

### 2. What types of identifiers exist?

The Colombian system identifies taxpayers through the **RUT (Registro Único Tributario)**, which is the registry that contains the NIT:

- **Business NIT:** Assigned by DIAN to corporations and foreign branches.
- **Individual NIT:** For Colombian citizens, this is typically their **Cédula de Ciudadanía (CC)** number plus a verification digit. For foreigners, it is often based on their **Cédula de Extranjería (CE)** or a DIAN-assigned number.
- **Foreign Entity NIT:** Required for foreign companies with a **Significant Economic Presence (SEP)** in Colombia or those owning assets in the country.

### 3. What is the format of the TIN in Colombia?

Colombian identifiers use a precise numeric sequence followed by a verification digit (Digit de Verificación - DV).

- **Structure:** Exactly **9 numeric digits**, a hyphen, and **1 verification digit** (e.g., `900.123.456-7`).
- **Verification Digit:** This single digit (0-9) is calculated using a specific **Modulo 11** algorithm.

> **Technical Insight:** In 2026, the **RADIAN** and electronic invoicing systems perform an instantaneous Modulo 11 check on the DV. If the verification digit is incorrect, the invoice is immediately rejected by DIAN's servers, preventing the transaction from being legally recognized for tax purposes. TaxDo’s GSV (Global Syntax Validation) incorporates this specific Colombian algorithm to catch errors before they enter your billing cycle.

### 4. Which authority issues the TIN?

The [DIAN (Dirección de Impuestos y Aduanas Nacionales)](https://www.dian.gov.co/) is the sole executive authority responsible for issuing NITs and managing the **RUT**. While individuals get their national ID from the Civil Registry, they must register with DIAN to activate their number as a functional NIT for tax purposes.

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

**Registration Thresholds & Mandates:**

- **General VAT (IVA):** The standard rate remains at **19%** for 2026\. Businesses with gross revenue exceeding **92,000 UVT** (approx. COP 4.8 billion) must file bimonthly.
- **Wealth Tax 2026:** A new emergency wealth tax applies to net worth exceeding **40,000 UVT** (approx. COP 2.1 billion), a lower threshold than previous years.
- **IPUSUI Tax:** As of February 2026, importers of single-use plastics must use **Form 3300** and a verified NIT to assess this new environmental tax.

### 6. How to register or apply for a TIN in Colombia?

Registration is conducted through the **RUT** process on the DIAN portal.

- **Step 1: Virtual Appointment:** Access the DIAN website to schedule a virtual or in-person session for "Inscripción en el RUT."
- **Step 2: Digital Signature:** Taxpayers must activate their **Firma Electrónica** (Electronic Signature) to sign tax returns and e-invoices.
- **Step 3: Significant Economic Presence (SEP):** Foreign digital service providers must register for a NIT to pay the **3% SEP tax** or be subject to a **10% withholding**.

- **Personal Liability:** Under the 2026 wealth tax reforms, mismatched NIT data can lead to individuals being audited for "Omitted Assets."
