This study investigates how tax knowledge and tax morale shape tax compliance behaviour among Malaysian university students. Data were collected using a structured questionnaire. The population in this study consists of UNITEN accounting students who registered in the diploma and degree programmes across the Academic Years 2023/2024 until 2025/2026. 49 completed responses were analysed using SPSS version 30. The findings suggested that tax knowledge and tax morale significantly influence students’ willingness to fulfil their future tax obligations. The results highlighted the value of strengthening tax education to prepare graduates who are not only skilled but also responsible and ethical taxpayers. The results also showed that gender and academic performance have no differences in tax compliance behaviour. By identifying key drivers of voluntary compliance under Malaysia’s Self-Assessment System (SAS), this study contributes to the growing body of literature on tax behaviour. The findings also offered useful guidance for policymakers and tax authorities seeking to refine tax policies and promote initiatives that improve tax literacy among young taxpayers.
