In the fast-evolving landscape of **2026**, Bangladesh has solidified its position as a “Smart Economy,” with the **National Board of Revenue (NBR)** completing its total digital overhaul.

For businesses operating in **Dhaka** or **Chittagong**, failing to validate a 12-digit TIN or a 13-digit BIN in real-time is the quickest way to trigger a bank account freeze or a “Red Lane” customs hold at Chattogram Port.

## Frequently asked questions

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

In Bangladesh, the Taxpayer Identification Number is known as the **e-TIN**.

- **For Businesses:** It is the mandatory 12-digit identifier for all legal entities.
- **For Individuals:** It is used by residents and non-residents to report income and file annual tax returns. In 2026, the e-TIN is the "master key" for the **integrated tax system**, linking your income tax profile directly to your VAT and Customs records.

### 2. What types of identifiers exist?

The Bangladeshi system utilizes a multi-layered identification strategy to ensure total fiscal visibility:

- **Business TIN:** A 12-digit number for corporate entities.
- **Business BIN (e-BIN):** A 13-digit **Business Identification Number** required for VAT purposes.
- **Business CORPORATENUMBER:** The registration number issued by the **Registrar of Joint Stock Companies and Firms (RJSC)**.
- **Individual NID:** The 10 or 17-digit National ID used to verify individual tax filings.
- **Individual TIN:** A 12-digit number for professional or high-income individuals.
- **Business OLDBIN:** The deprecated 11-digit numbers, which are now **invalid** in 2026.

### 3. What is the format of the TIN and BIN?

Bangladesh uses standardized numeric strings designed for high-speed algorithmic verification.

- **e-TIN Structure:** Exactly **12 numeric digits** (e.g., `123456789012`).
- **e-BIN Structure:** Exactly **13 numeric digits** (e.g., `000123456-0101`).
- **Technical Insight:** In **2026**, the NBR’s **IVAS (Integrated VAT Administration System)** performs a real-time checksum validation on the 13-digit BIN. Any invoice carrying an **OLDBIN** (11 digits) or a typo in the 13-digit sequence is automatically rejected by the system, making the transaction non-deductible for the buyer.

### 4. Which authority issues the identifiers?

The [National Board of Revenue (NBR)](https://nbr.gov.bd/) is the sole executive authority responsible for issuing TINs and BINs. While the RJSC handles business incorporation (Corporate Number), the NBR must activate the tax and VAT profiles before a company can legally trade.

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

**Registration Thresholds & Mandates:**

- **Mandatory BIN (VAT):** Any business with an annual turnover exceeding **BDT 30 million** must register for a 13-digit e-BIN.
- **Mandatory TIN:** Any individual or entity with taxable income or those wishing to obtain a trade license, car registration, or open a bank account.
- **Digital Platforms:** As of **January 2026**, non-resident digital service providers (SaaS, streaming, social media ads) must register for a BIN and pay **15% VAT**, regardless of their local physical presence.

### 6. How to register for a TIN or BIN?

Registration is 100% digital via the NBR's specialized portals.

- **Step 1: e-TIN Registration:** Visit the [e-TIN portal](https://secure.incometax.gov.bd/TINHome) and provide NID or RJSC details.
- **Step 2: e-BIN Registration:** Once the TIN is obtained, apply for the 13-digit BIN via the [VAT Online Portal](https://www.vat.gov.bd/).
- **Step 3: Verification:** For businesses, a physical address verification by a Revenue Officer may be triggered by the system’s risk-assessment algorithm before the BIN becomes "Active."
