GST stands for Goods and Services Tax. It is an indirect tax applied to the sale of goods and services and is commonly used in India as a unified tax system.
CGST and SGST are used for intra-state transactions, and the total GST is split equally between the central and state governments. IGST is used for inter-state transactions, where the full tax is charged as one combined tax.
To add GST, calculate the GST amount by multiplying the base amount by the GST rate and dividing by 100. Then add that GST amount to the original base amount to get the final price.
To remove GST, divide the GST-inclusive amount by 1 + (GST rate ÷ 100). This gives the base amount before tax. The difference between the inclusive amount and the base amount is the GST portion.
