What is GST?

Goods and Services Tax (GST) is a unified indirect tax system introduced in India on 1st July 2017. It replaced a web of previous taxes like VAT, service tax, excise duty, and others. GST brings "One Nation, One Tax", simplifying the tax structure and improving compliance for businesses.

It is levied at every step of the supply chain and is based on the value added at each stage. The final burden falls on the end consumer.

Types of GST

  1. CGST (Central GST) – Collected by the Central Government on intra-state sales.

  2. SGST (State GST) – Collected by the State Government on the same intra-state sales.

  3. IGST (Integrated GST) – Collected by the Central Government on inter-state sales and imports.

  4. UTGST (Union Territory GST) – Applies in Union Territories.

Benefits of GST for Businesses

  • Simplified Compliance – Single tax platform for all indirect taxes.

  • Seamless Input Tax Credit – Reduces cascading tax effects.

  • Nationwide Market – Promotes ease of doing business across states.

  • Digital Filing System – All returns and registrations are done online via the GST portal.

  • Transparent System – Encourages proper invoicing and discourages tax evasion.

GST Registration: Who Should Register?

You must register for GST if:

  • Your business turnover exceeds ₹40 lakhs (₹20 lakhs for special category states).

  • You are involved in inter-state supply of goods or services.

  • You operate an e-commerce business or supply through platforms like Amazon or Flipkart.

  • You are a casual taxable person or non-resident taxable person.

  • You are required to deduct TDS or collect TCS under GST.

Key Concepts to Understand

1. Input Tax Credit (ITC)

GST paid on purchases can be claimed back while paying GST on sales, reducing the overall tax liability.

2. HSN/SAC Codes

Unique codes used to classify goods (HSN) and services (SAC) for accurate GST filing.

3. GST Returns

Every registered business needs to file regular GST returns (monthly/quarterly/annually) such as GSTR-1, GSTR-3B, and GSTR-9.

4. Reverse Charge Mechanism (RCM)

In some cases, the recipient of goods/services is liable to pay GST instead of the supplier.

Penalties for Non-Compliance

  • Late filing fee: ₹50 per day (₹20 for NIL returns)

  • Interest on late payment: 18% per annum

  • Additional penalties for fraud or evasion

Staying compliant with GST laws is not optional — it's essential to avoid unnecessary financial burdens and legal trouble.

GST and Small Businesses

The GST regime has introduced Composition Schemes for small taxpayers with turnover up to ₹1.5 crore. This allows them to pay tax at a reduced rate with less compliance.

However, such businesses cannot claim input tax credit and must issue bill of supply instead of a tax invoice.

Expert Tip:

Regular GST compliance helps improve your business credibility, especially when dealing with larger clients, banks, or government tenders.
