In the modern era, tax education plays a vital role in preparing students to understand their financial responsibilities. As economies evolve, individuals need to grasp how taxes impact daily life and society. Introducing tax education at the higher secondary school level ensures students are informed and ready to engage with the taxation system. This early education promotes financial literacy, transparency, and civic responsibility, helping students make informed financial decisions and contribute responsibly to society's growth. Overall, tax education plays a vital role in fostering personal and societal development. This study aimed to develop and assess the effectiveness of an instructional package on tax education for enhancing tax awareness on various key components of tax education among higher secondary school students. An experimental research method with a pre-test post-test single-group design was adopted for this research. The study tested a sample of 115 higher secondary school students. The study utilized a Tax Awareness Test to measure outcomes. Pre-tests and post-tests were conducted, and data were consolidated using descriptive statistics and paired t-tests. Findings indicated that the instructional package significantly improved tax awareness among students, with positive results across all components of tax awareness. The study also provided potential recommendations for enhancing tax education among higher secondary students.
