The primary purpose of this paper is to examine how social sector expenditure influence India's progress toward attaining the Sustainable Development Goals (SDGs), with tax revenue acting as a moderating factor. The research was conducted between 2018 and 2020. The data used in this study came from secondary sources. Panel data are used in this work to estimate the results and to gain a deeper understanding. The significant findings of this study include that spending more on social sector expenditures leads to an increase in India's SDG, and there is no impact of tax revenue on social sector expenditures and the SDG of India. This research contributes to the conversation about effective policy interventions that can help promote the sustainable development of India by taking a comprehensive look at the connections between these variables. The main limitation of this study is that there is a concise span of data available for conducting this type of study.
