A National Tax Number (NTN) is a unique identifier assigned to individuals and businesses for tax purposes. It helps tax authorities track tax obligations and ensure compliance with tax laws. Having an NTN is essential for filing tax returns, making payments, and conducting various financial transactions. In many countries, obtaining an NTN is a straightforward process that involves submitting personal or business information to the relevant tax authority. This number is crucial for maintaining accurate tax records and can also be required when opening a bank account or applying for loans.
