How to Add GST to a Price (Tax Exclusive)

When you are selling a product or service and need to add GST on top of the base price, you are performing a 'Tax Exclusive' calculation. This is common in B2B transactions where prices are quoted before taxes. To add GST, you simply multiply the base amount by the tax rate and add it to the original price.

How to Remove GST From an Inclusive Price

In many retail scenarios (B2C), the price you see on the shelf (MRP) already includes GST. To find out the actual base price of the item and how much tax you've paid, you must 'remove' or 'extract' the GST. This is slightly more complex than adding GST because the tax was calculated on the original base, not the total price.

CGST vs SGST vs IGST — What is the Difference?

India follows a dual-mode GST system where tax is collected by both the Central and State governments. The type of GST applied depends on the location of the supplier and the recipient.

• CGST (Central GST): Applied on intra-state supplies (within the same state). Goes to the Central Government.
• SGST (State GST): Applied on intra-state supplies alongside CGST. Goes to the State Government.
• IGST (Integrated GST): Applied on inter-state supplies (between two different states) and imports. The full amount is collected by the Central Government and then distributed to the destination state.
• Rule of Thumb: On a local bill, CGST and SGST always share the total tax 50:50. For example, on an 18% item, you pay 9% CGST and 9% SGST.
