Introduction
Goods and Services Tax (GST) is one of the most significant tax reforms introduced in India. It has simplified the indirect taxation system by replacing multiple taxes with a single unified tax structure. Every business involved in the supply of goods or services must understand GST regulations to avoid penalties and ensure smooth operations.
Whether you are a startup, MSME, trader, manufacturer, service provider, or e-commerce seller, understanding GST compliance is essential for business growth. This complete legal guide explains GST registration, return filing, compliance requirements, penalties, and related tax obligations in simple words.
What is GST?

GST is categorized into:

SGST (State Goods and Services Tax)
IGST (Integrated Goods and Services Tax)
UTGST (Union Territory Goods and Services Tax)
The tax collected under GST is shared between the Central and State Governments.
