The study titled “Consumer Behavioural Shifts Post GST Exemption on HealthInsurance Premiums in Hosur” examines the changes in consumer attitudes, purchase intentions, and policy preferences following the removal of Goods and Services Tax (GST) on health insurance premiums. The exemption significantly reduced the overall cost burden on policyholders, thereby influencing affordability and accessibility of health insurance products. The primary objective of the study is to analyse how the GST exemption has affected consumer awareness, demand patterns, coverage selection, and renewal behaviour in Hosur. The research focuses on identifying whether consumers have shifted from low-coverage policies to higher sum insured plans and whether the exemption has encouraged first-time buyers to enter the health insurance market. Data for the study can be collected through structured questionnaires administered to policyholders and prospective buyers in Hosur.
