Understanding India's 'One Nation, One Tax' Goal

The question asks to identify the tax introduced in India specifically to fulfill the objective of 'One Nation, One Tax, One Market'. This slogan represents a major tax reform aimed at creating a unified and simplified indirect tax structure across the country.

Analyzing the Tax Options

Let's examine the options provided:

• Goods and Services Tax (GST): Introduced on July 1, 2017, GST replaced numerous indirect taxes levied by the central and state governments. It subsumed taxes like Value Added Tax (VAT), Central Excise Duty, Service Tax, and others. By having a single, unified tax structure applied across the country, GST directly aimed to achieve the 'One Nation, One Tax, One Market' objective, reducing tax barriers and promoting economic integration.
• Union Excise Duty: This tax is levied by the central government on the manufacture of goods. While important, it was one of the taxes that GST aimed to replace or subsume. It didn't, by itself, represent the 'One Nation, One Tax' initiative.
• Custom Duty: This is a tax imposed on goods imported into India. It's related to international trade and doesn't align with the goal of creating a unified domestic market structure ('One Nation').
• Security Transaction Tax (STT): This is a direct tax levied on specific transactions in the stock market. It is not an indirect tax related to the broader market unification goal mentioned in the question.

Conclusion on Tax Introduction

Based on the analysis, the Goods and Services Tax (GST) is the tax specifically introduced to achieve the ambitious goal of 'One Nation, One Tax, One Market'. It consolidated various indirect taxes into a single framework, streamlining the taxation process and fostering a more integrated national market.
