Understand what GST is, why it matters, how it's applied, and how to comply easily.

What is GST?

  • GST (Goods and Services Tax) is a unified indirect tax levied on the supply of goods and services across India.
  • It replaced multiple indirect taxes like VAT, Service Tax, and Excise Duty to simplify the tax structure.
  • GST is a destination-based tax, meaning it is collected by the state where the goods/services are consumed.

Types of GST in India

  • CGST: Central Goods and Services Tax, collected by the central government on intra-state sales.
  • SGST: State Goods and Services Tax, collected by the state government on intra-state sales.
  • IGST: Integrated Goods and Services Tax, collected by the central government on inter-state sales or imports.
  • UTGST: Applied in Union Territories like Delhi, Chandigarh, etc.

GST Rates in India

Who Needs to Register for GST?

  • Businesses with an annual turnover of ₹20 lakhs or more (₹10 lakhs in special category states).
  • E-commerce sellers, inter-state suppliers, and service providers crossing the limit must register.
  • Voluntary registration is also allowed for startups or small businesses wanting to avail input tax credit.

Why is GST Applied?

  • To bring uniformity in the tax system across India.
  • To eliminate the cascading effect of multiple taxes.
  • To improve tax transparency and compliance.
  • To make Indian businesses more competitive globally.

Input Tax Credit (ITC)

  • GST-registered businesses can claim credit for the GST paid on purchases used for business.
  • ITC helps reduce the final tax liability and avoid tax-on-tax (cascading tax).
  • Proper invoicing and GST returns filing are required to claim ITC.

Filing GST Returns

  • GST returns are filed monthly or quarterly based on turnover.
  • Common forms: GSTR-1 (sales), GSTR-3B (summary), GSTR-9 (annual).
  • Timely filing avoids penalties and ensures seamless ITC claim.
