With an emphasis on the revolutionary effects of the Goods and Services Tax Network (GSTN) in India, this study thoroughly compares indirect tax revenue performance in India, Canada, and Brazil. To assist the fiscal effectiveness of GST systems in these three economies, the study looks at revenue, trends, volatility, patterns, and correlation dynamics with GDP. Using quantitative research with the help of secondary data for the period of 2020 to 2024, the paper compares the GST implementation scenarios of India with a well- established GST framework in Canada and an indirect tax framework in Brazil, to evaluate the performance indicators of indirect tax systems. Key performance indicators include tax to GDP ratios, system stability metrics, revenue, growth rates, and correlation coefficients with economic growth indicators. The results show that the GST implementation in India has produced outstanding results, with revenue, growth of a hundred, and a tax-to-GDP ratio of 31.25%, highlighting the revolutionary potential of complete GST reform. Comparatively speaking, Canada and Brazil have more developed and stable systems, but India's system suggests that indirect tax administration has successfully undergone structural change. The research shows that India's GST system has substantially achieved its primary revenue enhancement and fiscal efficiency objectives. The stability and ideal GDP correlation seen in more developed systems like Canada are still challenging to achieve. Still, the overall success of India's transformation confirms the strategic digitalisation GSTN has taken. The comparative frame of the study demonstrates that well-designed GST systems, supported by strong digital infrastructure and ongoing improvement procedures, can significantly boost fiscal performance and further economic development objectives. To guarantee the continuous advancement of India towards reaching international benchmarks in indirect tax administration, the study suggests a constant emphasis on system optimisation, improved stakeholder participation, and sophisticated technological integration.
