Frequently Asked Questions
What does "GST inclusive" mean?▾
GST inclusive means the total price already includes GST. To find the base price, divide by (1 + GST rate). Example: ₹11,800 inclusive of 18% GST → base = ₹10,000, GST = ₹1,800.
How is IGST different from CGST+SGST?▾
The total tax is identical. IGST is collected by the centre for inter-state sales. CGST+SGST is split equally between centre and state for intra-state sales. The buyer pays the same amount regardless.
Do I need GST registration?▾
GST registration is mandatory if annual turnover exceeds ₹40 lakh for goods (₹20L for services, ₹10L for special category states). Voluntary registration is allowed for input tax credit benefits.
