Personal financial planning (PFP) is an emerging and expanding discipline, rooted in the foundational yet underappreciated work of Modigliani, Becker, and Markowitz. Due to its growing significance, PFP deserves greater academic recognition and further research. PFP is a comprehensive process encompassing all financial matters relevant to an individual for achieving personal economic satisfaction and long-term financial stability. This study explores the factors influencing personal financial planning behavior and attitudes towards PFP components among tax-paying and non-tax-paying government college teachers in the East Siang district of Arunachal Pradesh. The study also tries to explore the relationship between demographic variables and personal financial planning. A comprehensive survey, utilizing structured questionnaires and interviews, was conducted with 200 government college teachers in the district. Findings reveal that tax-paying teachers exhibit greater positive attitudes towards PFP components compared to non-tax-paying teachers. Significant association has also been found between attitude towards personal financial planning components and demographic variables like designation, income, tax-paying status, and regular saving habits, except for age and gender. Additionally, the study identifies eight crucial components of personal financial planning: money management, debt management, insurance, investments, taxation, estate planning, retirement planning, and overall PFP, all of which significantly impact the financial planning behavior of the respondents. A collaborative effort involving financial institutions, implementing agencies, educational institutions, and policymakers is necessary to implement tailored financial education programs to improve teacher financial awareness.
