- For Exclusive Amount: GST Amount = (Amount x GST Rate) / 100
- For Inclusive Amount: GST Amount = Amount - [Amount x (100 / (100 + GST Rate))]

Frequently Asked Questions (FAQs)
What is the difference between CGST, SGST, and IGST?
For Intrastate sales (within the same state), GST is split equally into CGST (Central GST collected by Central Gov) and SGST (State GST collected by State Gov). For example, an 18% GST sale in Tamil Nadu will be billed as 9% CGST + 9% SGST. For Interstate sales (between two different states) or imports/exports, IGST (Integrated GST) is charged at the full rate (18%) by the Central Government and shared with the destination state.
What is GST Input Tax Credit (ITC)?
Input Tax Credit (ITC) is the backbone of the GST regime. When a registered business purchases raw materials or goods for business use, it pays GST to the supplier. When it sells finished goods, it collects GST from the buyer. The business can deduct the GST paid on purchases (Input Tax) from the GST collected on sales (Output Tax) and pay only the net balance to the government, avoiding double taxation.
Who is mandatorily required to register for GST in India?
Any business dealing in the supply of goods whose annual aggregate turnover exceeds ₹40 lakh (₹20 lakh for special category North-Eastern states) must register for GST. For businesses providing services, the threshold limit is ₹20 lakh per financial year (₹10 lakh for special category states). Additionally, businesses engaged in e-commerce or interstate sales require mandatory registration regardless of turnover.
