What Is GST in India? Understanding Goods and Services Tax 2025

The Goods and Services Tax (GST) in India is a comprehensive, destination-based indirect tax that has replaced a complex web of multiple indirect taxes like VAT, excise duty, and service tax.
Launched on 1 July 2017, GST unified the nation into โ€œOne Nation, One Tax, One Market.โ€

It applies to almost every good and service consumed or sold in India, ensuring transparency, uniformity, and ease of compliance for businesses and consumers alike.

๐Ÿ’ก How Does GST Work?

Letโ€™s simplify the working of GST in India through a real-world example.

StageParticipantValue Added (โ‚น)GST @18%Input CreditTax Payable
1Manufacturer1,000180โ€“180
2Wholesaler50090180(90 – 180) = 0
3Retailer50090900
Totalโ€“2,000180 collected in totalโ€“โ€“

โœ… Explanation:
Each party pays tax only on the value addition, not on the total price โ€” thanks to Input Tax Credit (ITC).
This prevents tax-on-tax (cascading) and ensures smoother flow of credit across the supply chain.
