Frequently Asked Questions
What are the GST rates in India?
India has four main GST rates: 5% (essential goods, economy services), 12% (processed food, certain textiles), 18% (most services, electronics, standard manufactured goods), and 28% (luxury goods, automobiles, tobacco). Some items like basic food, healthcare, and education are exempt (0%).
What is the GST registration threshold in India?
GST registration is mandatory when annual aggregate turnover exceeds ₹20 Lakh for businesses in regular states (₹10 Lakh for special category states like Manipur, Mizoram, etc.). Some activities require mandatory registration regardless of turnover (e.g., inter-state supply, e-commerce sellers).
What is reverse GST calculation?
Reverse GST calculation extracts the base amount and GST from a GST-inclusive total. Formula: Base = Inclusive Price × 100 / (100 + GST%). Use this when a quoted price already includes GST and you need to show it separately on an invoice.
