Taxation plays a vital role in redistributing benefits and is crucial for economic development. Bangladesh is committed to enhancing revenue generation and maintaining fiscal discipline to achieve self-sufficiency. However, compared to other countries at similar stages of development, Bangladesh has one of the lowest tax-to-GDP ratios among SAARC nations. Despite some progress, there is still a need for improvement in performance. Enhancing tax compliance is pivotal in addressing this situation, and authorities have made tax returns mandatory for various categories, including individuals holding TIN certificates. Notably, individuals investing over Tk. Two lac in national savings certificates are required to submit a TIN certificate, making tax returns mandatory for them. This study aims to examine the influence of factors such as educational attainment, understanding of tax laws, tax office notices, and income level on the willingness of NSC investors to file tax returns. The research findings indicate that the attitude towards tax returns is influenced by those factors, which have been taken into account for the study.
