Professional GST consulting services help businesses remain compliant while maximizing tax efficiency.
What is GST?
Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. It replaced multiple indirect taxes such as VAT, service tax, excise duty, entry tax, and several state-level taxes.
GST follows a destination-based taxation system, meaning the tax revenue is collected by the state where goods or services are consumed rather than where they are produced.
The GST framework consists of:
- Central GST (CGST)
- State GST (SGST)
- Integrated GST (IGST)
- Union Territory GST (UTGST)
The objective of GST is to create a unified national market and simplify tax administration.
