GST: Goods and Services Tax

GST (Goods and Services Tax) is a nationwide indirect tax introduced in India on 1 July 2017. It is levied on the supply of goods and services and replaced multiple indirect taxes such as VAT, service tax, and excise duty. The goal was simple: one nation, one tax.

Why GST Matters

Before GST, taxes were applied at different stages and varied from state to state, making the system complex and expensive. GST brought uniformity, transparency, and simplicity to India’s tax structure.

Under GST:

Tax is added at each stage of supply but collected only on the final value
Businesses can claim input tax credit, avoiding tax-on-tax
Consumers see a clearer breakdown of taxes on bills

GST Tax Slabs

As per the latest structure, GST is divided into four main slabs:

0% – Essential goods
5% – Basic necessities
18% – Standard goods and services
40% – Luxury and sin goods

Some goods and services are fully exempt from GST.

Types of GST in India

GST is applied differently depending on where the transaction takes place:

CGST – Central GST

Collected by the Central Government on intra-state transactions (within the same state). CGST is charged along with SGST, usually at equal rates.

SGST – State GST

Collected by the State Government on intra-state transactions. It is applied alongside CGST.

IGST – Integrated GST

Collected by the Central Government on inter-state transactions and imports. The collected tax is later shared with the destination state.

UTGST – Union Territory GST

Applicable to transactions within Union Territories. It is charged along with CGST.

In Simple Terms

Buy within the same state? → CGST + SGST
Buy from another state or import? → IGST
Buy within a Union Territory? → CGST + UTGST

Conclusion

GST transformed India’s indirect tax system by making it more efficient, uniform, and business-friendly. For consumers and businesses alike, understanding GST helps in better compliance, smarter pricing, and clearer tax planning.
