What is Goods and Services Tax (GST)?

The **Goods and Services Tax (GST)** is a unified, destination-based indirect tax system implemented in India on July 1, 2017. Replacing a maze of cascading indirect central and state taxes like Excise duty, Value Added Tax (VAT), Service Tax, Entry Tax, and Octroi, GST has streamlined taxation under a single umbrella. Under the GST model, tax is levied at every point of value addition, making it comprehensive and multi-stage.

GST Categorization: CGST, SGST, & IGST

To ensure balanced fiscal distribution between the Central and State Governments, GST is divided into three major categories:

• CGST (Central GST): Collected by the Central Government on an intra-state transaction (e.g., selling goods within Maharashtra).
• SGST (State GST): Collected by the State Government on an intra-state transaction. It is always equal to CGST.
• IGST (Integrated GST): Collected by the Central Government on an inter-state transaction (e.g., selling goods from Karnataka to Tamil Nadu) and distributed accordingly.

Mathematical Formulas for GST Calculations

Our tool implements standard corporate tax formula algorithms:

1. GST Exclusive Formula (Adding GST to Original Price):
• GST Amount = Price × (GST Rate / 100)
• Gross Total Price = Original Price + GST Amount

2. GST Inclusive Formula (Removing GST from Gross Price):
• Net Taxable Price = Gross Price × [ 100 / (100 + GST Rate) ]
• GST Amount = Gross Price - Net Taxable Price

GST Tax Calculator FAQs

What is the difference between GST inclusive and exclusive prices?
GST Exclusive indicates the price of a product or service does not include tax yet; tax must be calculated and added to get the final bill. GST Inclusive means the tax is already integrated into the final retail price, and we must subtract the tax amount to find the net base cost.
What are the current standard GST tax rate slabs in India?
India currently operates on four major tax slab levels: 5% (common food items, basic necessities), 12% (utility services, mid-range items), 18% (electronic goods, services, standard items), and 28% (luxury items, automobiles, tobacco). Essential items like milk, grains, and salt are placed in the 0% exempt list.
How do I calculate CGST and SGST values?
For any intra-state transaction, the total GST amount is simply divided equally into two halves. 50% goes to the Central Government as CGST and 50% goes to the State Government as SGST.
