What is the difference between CGST and SGST?

For sales within the same state, GST is split equally. Half goes to the Centre (CGST) and half to the State (SGST). Together they equal the full GST rate.

How do I remove GST from a total price?

Divide the total by (1 + rate/100). For example, 1180 rupees at 18 percent gives a base of 1000 and 180 GST.

How GST is calculated

Add GST (price is exclusive of tax): GST = Amount × Rate ÷ 100, and Total = Amount + GST.
Remove GST (price already includes tax): Base = Total ÷ (1 + Rate ÷ 100), and GST = Total − Base.

For intra-state sales, the GST is split equally into CGST and SGST (half each). For inter-state sales it becomes a single IGST of the same total rate.

Common GST rates in India

Most goods and services fall under 5%, 12%, 18% or 28%. Essentials may be 0% (exempt), while luxury and sin goods sit at 28% (sometimes plus cess). Always confirm the correct HSN/SAC rate for your product.
