GST on Goods vs Services; GSTIN and GSTN

GST rules on goods vs services

GST applies a single unified law to the "supply" of both goods and services, but a few rules differ in their detail between the two, reflecting the practical difference between a physical item that can be moved/stored and a service that generally cannot:

AspectGoodsServices
What is taxedThe supply (sale, transfer, etc.) of a movable/tangible itemThe supply of an intangible activity/benefit
Place of supplyGenerally where the goods are delivered/moved toGenerally the location of the recipient (with specific rules for particular services)
Time of supplyGenerally linked to the invoice date or the date goods are made availableGenerally linked to the invoice date or the date payment is received, whichever is earlier, with its own specific rules
Registration thresholdA specified aggregate turnover threshold, which can differ between goods and services suppliers, and between StatesA specified aggregate turnover threshold, generally treated separately from the goods threshold

This unit's syllabus scope is conceptual — recognising that GST treats goods and services under one common law but with some distinct procedural rules (place of supply, time of supply, registration thresholds) — not detailed rate-by-rate computation.

GSTIN — GST Identification Number

Every person registered under GST is issued a GSTIN, a unique 15-character (digit-and-letter) identification number, structured as follows:

PositionWhat it represents
1st and 2nd digitsThe State code (as per the Census 2011 State code list) of the State in which the taxpayer is registered
Next 10 charactersThe taxpayer's Permanent Account Number (PAN)
13th characterA number assigned based on the number of registrations the same PAN holder has within that State (allowing more than one GST registration per PAN in one State, e.g. for different business verticals)
14th characterThe letter 'Z' by default
15th characterA checksum digit, used for error detection

GSTN — Goods and Services Tax Network

GSTN is the organisation that built and operates the common GST portal — the technology backbone of the entire GST system, handling taxpayer registration, return filing, tax payment, and invoice/input-tax-credit matching for the whole country. GSTN was originally structured as a non-Government, not-for-profit private company with a mix of Government and private financial-institution shareholding; it was later restructured (2018) into a fully Government-owned company, with the Central and State Governments together holding its entire equity, reflecting GST's status as a jointly-administered Centre-State tax. …
