Why GST Maths Trips Up Most Freelancers
GST on a ₹50,000 service invoice at 18% is ₹9,000 — split as ₹4,500 CGST + ₹4,500 SGST for intra-state supply, or ₹9,000 IGST for inter-state supply. The total invoice value the client pays is ₹59,000. The GST portion is pass-through to the government, not your revenue — your actual income is the ₹50,000 base.
Registration is mandatory if your annual turnover exceeds ₹20 lakh (services) or ₹40 lakh (goods) — ₹10 lakh in some hill states. Below that, you operate without GST. Voluntary registration is allowed and sometimes useful (business clients prefer GST-registered vendors so they can claim ITC), but it adds compliance — monthly or quarterly GSTR-1 + GSTR-3B filings.
Three frequent mistakes: (a) confusing GST with TDS — they’re separate. On a ₹50,000 professional invoice, client deducts ₹5,000 TDS (10% under 194J) AND pays ₹9,000 GST. Your net receipt: ₹50,000 − ₹5,000 TDS + ₹9,000 GST = ₹54,000, of which ₹9,000 is owed back to the government; (b) forgetting reverse charge mechanism (RCM) on certain services like advocates, GTA — buyer pays GST directly; (c) missing the composition scheme option for small businesses below ₹1.5 crore turnover — flat 1-6% GST without ITC, much lower compliance.
