Common Questions Answered

Quick help
Q1 What is Goods and Services Tax (GST)?
GST is a comprehensive, multi-stage, destination-based indirect tax levied on the supply of goods and services, designed to replace a multitude of other state and federal indirect taxes (such as VAT, service tax, and excise duty).
Q2 How do I calculate GST to add it to a net product price?
To add GST to a net price, use the formula: GST Amount = (Net Price x GST Percentage) / 100. The total Gross Price is then: Net Price + GST Amount.
Q3 How do I extract a net cost by removing GST from a gross price?
To extract and remove tax from a gross price, use the formula: Net Price = Gross Price / (1 + (GST Percentage / 100)). The absolute tax amount is then: Gross Price - Net Price.
Q4 What is the difference between CGST, SGST, and IGST?
CGST (Central GST) and SGST (State GST) apply to transactions within a single state, and the tax is split 50/50 between federal and state governments. IGST (Integrated GST) is applied to interstate trade and is collected by the central government.
Q5 Are my financial transactions or sales prices tracked?
Absolutely not. All tax calculations and CGST/SGST splits are computed locally within your browser sandbox. None of your data is sent to external databases or servers.
