The introduction of the Goods and Services Tax (GST) in 2017 marked a major turning point in India’s fiscal landscape. By subsuming multiple state-level indirect taxes under a single, unified system, GST promised to simplify taxation and create a truly national market. But beyond these efficiency gains, an important question arises: has GST changed how tax revenue is distributed across Indian states? In particular, has it reduced inter-state revenue inequality or reinforced existing disparities?
Gorti et al. (Wed,) studied this question.
