This unique identifier plays a pivotal role in reporting income, paying taxes, and conducting any official transactions with the tax authorities. It is crucial to have the correct TIN for accurate tax reporting and to avoid legal complications. All data presented in this guide has been fully verified through official tax authority websites and trusted government sources, ensuring the highest level of accuracy and reliability. ## **Tax Identification Number Types** Kazakhstan uses a single type of Tax Identification Number (TIN) across all categories of taxpayers, including individuals, businesses, and legal entities. The local name for this number is the **Individual Identification Number (IIN)** for individuals and the **Business Identification Number (BIN)** for legal entities. Here’s a breakdown: - **IIN (Individual Identification Number)**: Issued to individuals for personal tax identification and registration. - **BIN (Business Identification Number)**: Issued to legal entities, including companies, for business tax identification. **Application:** - **IIN**: Required for all individuals in Kazakhstan, including residents and non-residents who are obligated to pay taxes in Kazakhstan. - **BIN**: Required for legal entities, such as companies or businesses, operating in Kazakhstan. These identifiers are essential for proper registration with the tax authorities and ensuring that the taxpayer complies with all relevant tax obligations. ## **TIN Format and Structure** **IIN Format (for individuals):** - **Structure**: The IIN is a 12-digit number. - The first part (the first six digits) represents the birth date of the individual (DDMMYY). - The next five digits are a unique sequence, assigned at the time of registration. - The last digit is a checksum used to validate the IIN’s authenticity. **Example**: 920701123456 (where 920701 is the birthdate, and the remaining part is a unique identifier). **BIN Format (for legal entities):** - **Structure**: The BIN is a 12-digit number. - The first part represents a code identifying the type of business. - The subsequent digits are used to identify the specific business entity. - The final digits form a checksum to validate the BIN’s correctness. **Example**: 171234567890 (where the first digits represent the business code, followed by a unique identifier for the legal entity). ## **Issuing Authority and Registration Process** **Issuing Authority:** The **State Revenue Committee** of the Ministry of Finance of the Republic of Kazakhstan is the official body responsible for issuing TINs in the country.
