The government has made it compulsory to submit income tax return proof when opening or maintaining fixed deposits and savings certificates over 10 lakh taka, or taking loans exceeding 20 lakh taka. Bangladesh Bank issued a circular enforcing this rule across 24 financial and banking services, including company director appointments, trade license renewals, and utility connections. Failure to comply will result in denial of these services by banks and government agencies, aiming to widen tax compliance nationwide.
