Frequently Asked Questions
What is GST?
GST (Goods and Services Tax) is a unified indirect tax levied in India on the supply of goods and services, replacing multiple cascading taxes.
What are the GST slabs in India?
India has four main GST slabs: 5% (essential goods/services), 12% (standard goods), 18% (most services), and 28% (luxury/sin goods). Some goods have 0% (exempt) or 3% (gold).
What is CGST and SGST?
For intra-state transactions, GST is split equally between CGST (Central) and SGST (State). For inter-state, IGST (Integrated) equals the total GST rate.
How do I reverse-calculate GST?
If the GST-inclusive price is ₹118 (at 18%), the base price = 118 / 1.18 = ₹100. Our calculator handles this automatically.
