What we assume
When GST applies, who charges it, and what is / isn't covered.
CGST / SGST / IGST split, e-invoicing thresholds, HSN codes.
Heads up. For situations involving international income, business income, or capital gains, always cross-check with a qualified Chartered Accountant before acting on these numbers.
Intra-state supply (within the same state): tax split equally into CGST (goes to Central Government) and SGST (goes to State Government). Inter-state supply (across states): full tax collected as IGST, shared between Centre and consuming state.
Specified notified services (legal services by advocate, GTA, renting motor vehicle, security services, etc.) require the recipient to pay GST under reverse charge — the supplier does not charge GST on the invoice. RCM transactions must be reported in GSTR-3B and ITC claimed on the same return.
For goods: location of delivery. For services: location of the recipient (general rule) or place of consumption for specific services. Inter-state vs intra-state determination drives whether CGST+SGST or IGST applies.
Small taxpayers (aggregate turnover up to ₹1.5 crore for both goods and service providers, Notification No. 14/2019-CT w.e.f. 1-Apr-2019) can opt for the composition scheme at a flat 1% (manufacturers / traders), 5% (restaurants) or 6% (services) tax rate. Cannot charge GST on outward supplies, cannot claim ITC, cannot make inter-state supplies, cannot supply through e-commerce operators.
