Frequently Asked Questions

What are GST slabs in India? +
India has 4 main GST slabs: 5% (essentials like packaged food), 12% (clothing under ₹1000, processed food), 18% (most goods/services like soap, electronics), 28% (luxury items like cars, ACs, tobacco — often with cess).
Difference between CGST, SGST, and IGST? +
CGST (Central) + SGST (State) apply to intra-state transactions, split equally (e.g., 18% = 9% CGST + 9% SGST). IGST applies to inter-state transactions as a single 18%. Total tax burden is same.
How to remove GST from inclusive price? +
Formula: Base Price = Inclusive Price ÷ (1 + GST%/100). Example: ₹1180 inclusive at 18% → ₹1180 ÷ 1.18 = ₹1000 base + ₹180 GST. Use this when MRP includes GST and you need pre-tax amount.
Who needs GST registration? +
Mandatory if turnover exceeds ₹40 lakhs (goods) or ₹20 lakhs (services). Lower limits in special category states (₹20L/₹10L). E-commerce sellers, inter-state suppliers, and casual taxpayers need GST regardless of turnover.
Is GST charged on discount? +
If discount is shown on invoice and recorded in books, GST is charged on POST-discount amount. Trade discount → GST on net. Cash discount given later → GST on full amount. Always mention discounts on invoice for tax savings.
