What does section 1 regulate?

It regulates short title, extent and commencement. Read the exact text, conditions, exceptions and transaction date together.

Which subordinate law should be checked?

No direct CGST Rule has been certified in this phase. Notifications, circulars, forms and the corresponding SGST/UTGST layer may also apply.

What evidence should be retained?

Preserve the contract or transaction record, invoice or form, portal acknowledgement, payment/ledger evidence, correspondence, legal working and the official source version used.

Can portal behaviour override the statute?

No. Portal functionality is operational evidence; legal entitlement and liability remain controlled by the Act, Rules, notifications and binding decisions.

Finin2min Summary - Section in 2 Minutes

Sub-section (1): names the legislation. Sub-section (2): applies it across India. Sub-section (3): permits provision-wise commencement through Gazette notifications, so “commencement” can differ by section.

Exact operative text

1. Short title, extent and commencement.- (1) This Act may be called the Central Goods and Services Tax Act, 2017. (2) It extends to the whole of India. (3) It shall come into force on such date as the Central Government may, by notification in the Official Gazette, appoint: Provided that different dates may be appointed for different provisions of this Act and any reference in any such provision to the commencement of this Act shall be construed as a reference to the coming into force of that provision.

The mapping is a legal concordance, not a round-robin related-link list. It is limited to instruments certified in this phase.

Practical example

Sections 1 and 2 came into force on 22 June 2017. A professional must still check the notified commencement date of any other section before applying it to a period. TERRITORIAL HISTORY The original territorial exclusion for Jammu and Kashmir was removed through the 2017 extension legislation with effect from 8 July 2017. Later reorganisation/adaptation instruments changed Union- territory references. Current work should use the operative “whole of India” text. Connected CGST Rules - Chapter I RULE 1 - BARE TEXT 1. Short title and Commencement.- (1) These rules may be called the Central Goods and Services Tax Rules, 2017.

(2) They shall come into force with effect from 22nd June, 2017.

RULE 2 - BARE TEXT 2. Definitions.- In these rules, unless the context otherwise requires,-

(a) “Act” means the Central Goods and Services Tax Act, 2017 (12 of 2017);

(b) “FORM” means a Form appended to these rules;

(d) “Special Economic Zone” shall have the same meaning as assigned to it in clause (za) of section 2 of the Special Economic Zones Act, 2005 (28 of 2005);

(e) words and expressions used herein but not defined and defined in the Act shall have the meanings respectively assigned to them in the Act. RULE DECODE Rule 2 creates a compact interpretation bridge: “Act”, “FORM” and “section” are internal labels; SEZ uses the SEZ Act meaning; and undefined expressions borrow their CGST Act meanings. RULES STATUS No Chapter I amendment to Rules 1-2 was identified in the official amendment/index trail reviewed through the legal cut-off. The official consolidated Rules PDF itself is dated 1 June 2021, so the index check is disclosed separately.

Section 2 - All 124 operative definitions The text below follows the official India Code consolidation. Editorial amendment brackets and footnote numerals are removed for readability; the amendment trail is preserved separately. Clause (18), which formerly defined “business vertical”, is omitted and therefore not counted as operative.
