Frequently Asked Questions

What is GST?
GST (Goods and Services Tax) is a consumption tax levied on goods and services. In India, it has four slabs: 5%, 12%, 18%, and 28%. Many countries including Australia, Canada, and Singapore also use GST.
What is the difference between CGST and SGST?
CGST (Central GST) is collected by the central government, and SGST (State GST) is collected by the state government for intra-state transactions. Both are half the total GST rate.
How do I remove GST from a total price?
Use "Remove GST" mode and enter the GST-inclusive amount. Formula: Base Price = Total ÷ (1 + GST rate). For example: ₹1,180 at 18% GST → ₹1,180 ÷ 1.18 = ₹1,000 base price.
Is GST the same as VAT?
They are similar concepts — both are consumption taxes applied at each stage of the supply chain. GST replaced VAT in India in 2017. Australia, NZ, Canada and others use GST; European countries use VAT.
