In Bangladesh, the Electronic Tax Identification Number (eTIN) is a unique identification number issued by the National Board of Revenue (NBR) to individuals and entities for tax purposes. The eTIN system streamlines the tax registration process, allowing taxpayers to register online and receive their TIN electronically. This initiative has significantly enhanced efficiency, reducing paperwork and processing time. With an eTIN, individuals and businesses can fulfill their tax obligations, including filing tax returns and paying taxes online. Moreover, the eTIN facilitates transparency and accountability in the tax system, enabling the government to track taxpayers’ transactions and combat tax evasion effectively. Overall, the eTIN system plays a pivotal role in modernizing the tax administration in Bangladesh and promoting a culture of compliance among taxpayers.
