## Frequently asked questions

### 1. What is a TIN in Ivory Coast?

In Ivory Coast, the traditional Tax Identification Number (TIN) is the **Compte Contribuable (NCC)**. However, since 2020 and into 2026, this has been superseded by the **Identifiant Unique (IDU)** for all new business registrations.

- **For Businesses:** The **IDU** is the single, unique reference used for tax, customs, and social security.
- **For Individuals:** Identification is based on the **Numéro d'Identification Unique (NIU)** or the **NNI** found on the national ID card.

### 2. What types of identifiers exist?

Ivory Coast utilizes a specialized set of codes to manage commercial and fiscal life:

- **IDU (Identifiant Unique):** The "Universal ID" for companies, issued by **CEPICI**.
- **NCC (Numéro de Compte Contribuable):** The legacy tax number, still used in many digital systems as the primary tax key.
- **RCCM (Registre du Commerce et du Crédit Mobilier):** The commercial registration number (e.g., `CI-ABJ-03-2026-B12-12345`).
- **NIU / NNI:** Personal identifiers for natural persons, residents, and citizens.

### 3. What is the format of the IDU and NCC?

Ivorian identifiers are designed for the **e-impôts** portal’s algorithmic validation.

- **The IDU Structure:** A 13-digit alphanumeric code (e.g., `IDU-1-12345678-X`).
- **The NCC Structure:** Exactly **7 numeric digits followed by a letter** (e.g., `1234567A`).
- **The RCCM Structure:** Follows the OHADA regional standard, indicating the country, city, and year of registration.

**Technical Insight:** In 2026, the **DGI (Direction Générale des Impôts)** uses the **IDU** as the primary routing address for the **Electronic Invoicing System (e-facture)**. If your IDU or NCC fails the checksum or is "Inactive" in the DGI master file, your digital invoices will be rejected at the source, making them legally void for VAT recovery by your clients.

### 4. Which authority issues the TIN/IDU?

The [CEPICI (Centre de Promotion des Investissements en Côte d'Ivoire)](https://www.cepici.gouv.ci/) is the "Single Window" authority responsible for issuing the **IDU** and **RCCM** during business incorporation.

The [Direction Générale des Impôts (DGI)](https://www.e-impots.gouv.ci/) manages the tax activation of these numbers and the issuance of the **Attestation de Régularité Fiscale (ARF)**.

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

**Registration Thresholds & Mandates:**

- **Mandatory Registration:** Every professional entity (Company, NGO, or Individual Business) must obtain an IDU/NCC before starting operations.
- **VAT (TVA) Threshold:** Registration is mandatory for businesses with an annual turnover exceeding **CFA 200 million** (for general regimes) or **CFA 50 million** (for simplified regimes).
- **Mandatory E-Filing 2026:** All businesses registered with the **DGE (Direction des Grandes Entreprises)** or **DME (Direction des Moyennes Entreprises)** must file and pay taxes exclusively via the **e-impôts** portal.
- **Non-Residents:** Foreign digital service providers must register for VAT if they have a "significant economic presence" in Ivory Coast, regardless of physical headquarters.

**Tax Rates (2026):**

- **Standard VAT (TVA):** 18%.
- **Corporate Tax (IS):** 25% (Standard).

### 6. How to register for a TIN (IDU) in Ivory Coast?

The process is centralized through the CEPICI "Guichet Unique" to ensure rapid market entry.

- **Step 1: Incorporation:** Submit your articles of association at CEPICI to receive your **RCCM** and **IDU** simultaneously.
- **Step 2: Tax Activation:** Log in to the **e-impôts** portal to activate your tax profile using your IDU.
- **Step 3: ARF Request:** Obtain your first Tax Clearance Certificate to open bank accounts and sign contracts.
- **Step 4: NIU for Individuals:** For foreign managers or individual consultants, apply for a **NIU** at the DGI with a valid passport.

### 7. How to verify an Ivorian Tax ID (IDU/NCC)?

Verification is the only way to ensure your partners are "Tax Regular" and your VAT deductions are safe.

- **Official Search:** Use the [DGI e-impôts portal](https://www.e-impots.gouv.ci/) to verify the validity of an NCC or IDU.
- **RCCM Search:** Verify the legal standing of a company via the [RCCM.ci](https://www.rccm.ci/) platform.

| **e-impôts Portal**  | Filing monthly VAT and salary tax (ITS) returns.       | **Blocker:** You cannot log in or submit declarations without a verified NCC/IDU.               |

### 10. What happens if a TIN (IDU) is incorrect or missing?

The DGI has implemented "Automated Audit Triggers" for the 2026 fiscal year.

- **VAT Deduction Denial:** If you trade with a supplier using an invalid IDU, the DGI will disallow your **18% VAT** deduction.
- **Customs Gridlock:** An incorrect IDU on a customs manifest prevents the clearance of goods, leading to expensive demurrage fees.
- **Payment Blockers:** Major corporate clients (DGE/DME) will automatically "reject" any invoice where the IDU/NCC does not match the national directory.
- **Account Freezes:** Under 2026 banking regulations, accounts with unverified or outdated RCI/IDU data may be restricted for international transfers.
