Frequently asked questions
How do I remove GST from a price?
Base = Total ÷ (1 + rate/100). For 18% GST on ₹1,180: 1,180 ÷ 1.18 = ₹1,000 base and ₹180 GST.
What is CGST and SGST?
For sales within a state, GST is split equally: half Central GST and half State GST. Inter-state sales use IGST instead.
Which GST rate applies to my product?
Rates depend on HSN/SAC codes. Check the official GST rate schedule or ask your accountant.
