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.
