In Bangladesh, obtaining an e-TIN (Electronic Tax Identification Number) does not automatically mean you must submit a return, but the NBR mandates return submissions for a wide category of individuals. Generally, any resident Bangladeshi whose annual total income exceeds the tax-free threshold (which typically ranges between BDT 350,000 and BDT 375,000 depending on the specific assessment year) must file a return.

However, even if your income is below this threshold, return submission is mandatory if you own specific assets, such as a motor car, or a property in any city corporation area. Furthermore, professionals like doctors, lawyers, chartered accountants, and engineers, as well as individuals holding trade licenses, participating in government tenders, or occupying executive positions in businesses and NGOs, are legally required to file annually. The government has broadened these mandatory submission rules to formalize the economy, meaning that failing to submit a return when required can result in financial penalties, delayed processing of vital services, and a substantially higher rate of Tax Deducted at Source (TDS) on your banking channels.
