This study seeks to examine the effects of the implementation of Goods and Services Tax (GST) on the accounting practices of Chartered Accountant (CA) firms in India. Since its introduction in 2017, the GST has significantly transformed the landscape of indirect taxation, influencing how businesses and professionals approach financial reporting and compliance. The study delves into changes in accounting methodologies, the advisory roles of clients, the workload associated with compliance, and the adoption of technology by CA firms. Utilizing both primary and secondary data, the research assesses how these firms have adjusted to the GST framework, the challenges encountered, and the opportunities that have arisen. The findings reveal that while GST has simplified tax reporting processes, it has simultaneously heightened the complexity and frequency of compliance requirements, leading CA firms to invest in automation and digital solutions.
