Understanding GST Basics: A Complete Guide for Indian Businesses

Goods and Services Tax (GST) revolutionized India's indirect tax system in 2017. Whether you're a small business owner, freelancer, or corporate entity, understanding GST is essential for compliance and growth.

What is GST?

GST (Goods and Services Tax) is a comprehensive indirect tax levied on the manufacture, sale, and consumption of goods and services throughout India. It replaced multiple cascading taxes like VAT, service tax, excise duty, and others, creating a unified tax structure.

Key Features of GST

• One Nation, One Tax: Unified tax system across all states
• Destination-based: Tax collected where goods/services are consumed
• Eliminates Cascading: Tax credit available at every stage
• Digital Infrastructure: Online registration, filing, and payments

Types of GST

1. CGST (Central GST)

Collected by the Central Government on intra-state supplies. Rate is 50% of the total GST.

2. SGST (State GST)

Collected by the State Government on intra-state supplies. Rate is 50% of the total GST.

3. IGST (Integrated GST)
