The Goods and Services Tax (GST) is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax: comprehensive because it has subsumed almost all the indirect taxes except a few state taxes. For a business or a freelancer in India, navigating GST is an essential aspect of compliance.
CGST
Collected by Central Government on intra-state sales.
SGST
Collected by State Government on intra-state sales.
IGST
Collected for inter-state sales across state borders.
Tax Slabs for 2026
The GST council categorizes products and services into primary tax slabs: 5%, 12%, 18%, and 28%. Essential items often fall under the exempted category (0%), while necessary goods typically see lower bounds of 5% or 12%. Premium or luxury goods attract the highest 28% bracket alongside additional cess in some cases.
Using the GST Calculator
Calculating reverse calculations to find the base value of an item or generating the final invoice number can involve tedious arithmetic. The mathematical formula for adding GST is `Amount + (Amount x (Rate/100))`, while removing GST requires the formula `Amount - (Amount x (100 / (100 + Rate)))`.
Our GST Calculator eliminates manual errors, allowing professionals to compute CGST, SGST, inter-state IGST, and Reverse Charge Mechanisms (RCM) within fractions of a second.
