Quickly calculate Goods and Services Tax (GST). Add GST to a base amount or remove GST from a tax-inclusive total.
Use this free GST split calculator to divide the total GST amount into its CGST and SGST parts for intra-state invoices.
A GST split calculator divides the total GST amount into its two equal components: CGST (Central GST) and SGST (State GST). For intra-state transactions, the GST is always split 50-50 between the central and state governments. This tool does that split instantly.
For example, for an 18% GST rate, the split is 9% CGST and 9% SGST. This calculator shows the rupee amounts for each component based on the base price you enter.
You need to split GST whenever you are creating a tax invoice for a sale within the same state. Indian GST law requires you to show CGST and SGST as separate line items on intra-state invoices.
If you only know the total GST amount and need the split, this calculator is the fastest way to get the correct CGST and SGST figures.
The total GST rate is always split exactly in half between CGST and SGST for intra-state sales. A 5% rate splits into 2.5% each. A 12% rate splits into 6% each. An 18% rate splits into 9% each. A 28% rate splits into 14% each.
This calculator shows both the percentage split and the rupee amounts so you can fill your invoice correctly.
On an intra-state GST invoice, list the base price first. Then add two separate tax lines: one for CGST with its percentage and amount, and one for SGST with the same percentage and amount. The totals of both add up to the full GST amount.
Never combine CGST and SGST into a single line on a tax invoice. They must appear separately for compliance.
For inter-state sales (seller and buyer in different states), use IGST instead of splitting into CGST and SGST. The IGST rate equals the full combined GST rate. There is no split for inter-state transactions.
The Tez Invoice IGST calculator handles inter-state GST calculations separately.
