📌 What is GST and Why is Registration Necessary?

Understanding GST in Simple Terms

The Goods and Services Tax (GST) is a unified, destination-based indirect tax levied on the supply of goods and services across India. Introduced on 1st July 2017, GST subsumed multiple indirect taxes like VAT, Service Tax, and Excise, making tax compliance simpler and more transparent.

Why Register for GST?

• Legally mandatory if your turnover exceeds the threshold.

• Needed for issuing tax invoices and collecting GST.

• Essential for claiming Input Tax Credit (ITC), reducing overall tax liability.

• Builds trust with customers and vendors, especially large corporates & government.
