GST in India — Complete Guide for FY 2024-25
Everything you need to know about GST rates, CGST/SGST/IGST, registration, return filing, Input Tax Credit, and compliance in India.
What Is GST & How Does It Work?
Goods and Services Tax (GST) is India's comprehensive indirect tax that replaced a complex web of central and state taxes — including Central Excise, Service Tax, VAT, CST, Entry Tax, Octroi and over 17 other levies — on 1st July 2017. It is a destination-based, consumption tax levied at every stage of the supply chain, with seamless Input Tax Credit (ITC) flow from manufacturer to consumer.
GST in India operates as a dual-levy system: the central government and state governments both levy GST simultaneously. On intra-state transactions, CGST (Central GST) and SGST (State GST) are each 50% of the total rate. On inter-state transactions, IGST (Integrated GST) equals the full rate and is collected by the centre, with the consuming state's share transferred from the IGST pool.
The GST Council — a constitutional body comprising the Union Finance Minister and all State Finance Ministers — decides GST rates, exemptions, and policy changes. The 53rd GST Council meeting in June 2024 made significant rate rationalisation changes, and further rate consolidation is expected in upcoming meetings.

Input Tax Credit — How ITC Works
Manufacturer buys raw materials
Pays ₹1,800 GST on ₹10,000 purchase (18%)
Manufacturer sells finished goods
Collects ₹3,600 GST on ₹20,000 sale (18%)
Net GST payable to government
₹3,600 − ₹1,800 ITC = ₹1,800 net GST
✓ No tax on tax — ITC ensures GST is levied only on the value added at each stage.
Input Tax Credit (ITC) — The GST Backbone
Input Tax Credit (ITC) is what makes GST non-cascading — it prevents tax-on-tax. At each stage of supply, a registered business can claim credit for GST paid on inputs (purchases) and set it off against GST payable on output (sales), paying only the net difference to the government.
ITC is available only when: (1) you are GST-registered; (2) you hold a valid tax invoice or debit note; (3) goods/services have been received; (4) your supplier has paid the GST and filed GSTR-1/GSTR-3B; (5) you have filed your own return. The matching of ITC claimed in GSTR-3B with GSTR-2B (auto-populated from supplier's GSTR-1) is critical — mismatches trigger ITC reversal demands with interest.
Blocked credits under Section 17(5) — ITC cannot be claimed on: motor vehicles for personal use, food & beverages, employee club memberships, beauty treatment, health & fitness services, life/health insurance (except mandatory by law), and goods/services used for personal consumption or construction of immovable property for personal use.
