Tips and limits
Since 22 September 2025 India's main GST slabs are 5% and 18%, with 40% for certain luxury and sin goods, and 0% for exempt items. The old 12% and 28% slabs no longer apply to most goods, though you can enter any rate using Custom. Always confirm the correct rate for your product or service with the official GST rate schedule or a tax professional.
