Rules 1 and 2 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rules 1 and 2 are the opening pair of the Central Goods and Services Tax Rules, 2017. Rule 1 gives the Rules their name and the date they came into force; rule 2 defines five terms and, in its last clause, sends every other word back to the Central Goods and Services Tax Act, 2017.
This article follows the CGST Rules as amended up to 31 October 2025 in the compilation consulted; notifications issued after that date should be checked.
Rule 1(1) says the Rules may be called the Central Goods and Services Tax Rules, 2017, and rule 1(2) says they came into force with effect from 22nd June, 2017. Rule 2 defines "Act", "Form", "Section" and "Special Economic Zone", and clause (e) says that any other word or expression not defined in the Rules but defined in the Act carries the meaning the Act gives it. The Rules are subordinate to the Act and are read with it, never alone.
Why these two rules matter although they look small
Almost every question about the Rules begins with a word. Is a "Form" something you download, or something the Rules print? Does "section" in rule 22 mean a section of the Act or of the Rules? What does "registered person" mean when the Rules never define it? Rules 1 and 2 answer all three, and the answers are short enough to learn once.
The Rules are made under the Act. For the rule-making power itself, see our post on section 164 of the CGST Act, 2017. For the definitions the Rules borrow, see sections 1 and 2 of the CGST Act. If you are about to apply for a GSTIN and want the procedure rule by rule, our GST registration service deals with it end to end.
Rule 1: short title and commencement
Rule 1 is headed "Short title and commencement". It has two sub-rules.
Sub-rule (1). "These rules may be called the Central Goods and Services Tax Rules, 2017." This is the formal name used throughout this series of articles, and the name an order, notice or form refers to when it cites a rule.
Sub-rule (2). "They shall come into force with effect from 22nd June, 2017." The rule prints that single date and nothing else. It does not stagger the Rules by Chapter and it does not leave any part to a later notification. When a particular rule has been inserted or changed later, the footnote under that rule records the amending notification; that is a matter for the rule concerned, not for rule 1.
The heading. The heading of rule 1 shows that a word was omitted from it. The footnote records that the omission was made by Notification No. 7/2017 - CT dated 27.06.2017, with effect from 22.06.2017. Only the heading was amended; the two sub-rules above are the whole of the rule.
Rule 2: the five definitions
Rule 2 opens: "In these rules, unless the context otherwise requires, -". The words "unless the context otherwise requires" matter. A meaning given in rule 2 is the default, and a rule whose own wording points elsewhere is read according to that wording.
| Clause | Term | What rule 2 says |
|---|---|---|
| (a) | "Act" | The Central Goods and Services Tax Act, 2017 (12 of 2017) |
| (b) | "Form" | A Form appended to these rules |
| (c) | "Section" | A section of the Act |
| (d) | "Special Economic Zone" | The same meaning as assigned to it in clause (za) of section 2 of the Special Economic Zones Act, 2005 (28 of 2005) |
| (e) | Other words and expressions | Words and expressions used in the Rules but not defined in them, and defined in the Act, have the meanings respectively assigned to them in the Act |
Clause (a): "Act"
Wherever a rule says "the Act", it means the Central Goods and Services Tax Act, 2017. It does not mean the IGST Act, the UTGST Act or any State Act. A rule that needs one of those says so by name.
Clause (b): "Form"
"Form" means a Form appended to the Rules. This is why the Rules name forms in capitals, such as FORM GST REG-01 or FORM GSTR-3B: the name is a reference to a prescribed Form, and the rule that names it states who files it and when. The Forms themselves are annexed to the Rules and are not reproduced in this article; where an article in this series names a Form, it says only what the rule's own words say about it.
Clause (c): "Section"
"Section" means a section of the Act. So when rule 3 speaks of an option "under section 10", it is section 10 of the CGST Act, 2017. The convention is useful in practice: in this series we write "section" for the Act and "rule" or "sub-rule" for the Rules, and clause (c) is the reason the two can never be confused inside the Rules.
Clause (d): "Special Economic Zone"
This is the only term that rule 2 defines by pointing outside the GST law. It takes the meaning given in clause (za) of section 2 of the Special Economic Zones Act, 2005 (28 of 2005). The Rules therefore do not carry their own description of a zone. Because that definition sits in another Act, the reader should check the current law for the corresponding provision rather than assume the clause number is unchanged.
Clause (e): everything else
Clause (e) is the one with the widest reach. A rule may use "registered person", "proper officer", "common portal", "electronic credit ledger" or "taxable person" without defining it. Clause (e) supplies the meaning: if the Act defines the expression, the Rules take the same meaning. Two points follow.
- The Rules do not repeat the Act's definitions, so a reader who looks only at the Rules will not find them.
- If the expression is defined in neither place, clause (e) gives no help, and the ordinary reading of the rule applies.
The clause works one way: the Act's meaning flows into the Rules. It does not say that a meaning given in rule 2 flows back into the Act.
A worked example
Assume that Meera Textiles Private Limited, an invented company, is reading a rule that says a registered person "shall electronically file" an intimation "on the common portal". The company's accountant, Rohan, asks three questions.
- Is this rule in force? Rule 1(2) says the Rules came into force with effect from 22nd June, 2017. For any later amendment to the particular rule, Rohan looks at the footnote under that rule for the notification that made it.
- What is the "Form" the rule refers to? Under clause (b) it is a Form appended to the Rules. Rohan looks for the Form by the name the rule prints.
- What is a "registered person" and what is the "common portal"? Neither is defined in rule 2. Under clause (e), Rohan reads the definitions in section 2 of the Act, and the rule then takes those meanings.
That is the whole method: date from rule 1, Forms from clause (b), sections from clause (c), and every unlisted word from the Act through clause (e).

| What is a "Section"? | Rule 2(c) | A section of the Act |

Points to watch
- Read the footnotes. Rule 1 itself was touched only in its heading. The text of rule 2 carries no amendment mark in the compilation consulted.
- "Unless the context otherwise requires". If a rule uses a word in a way that does not fit the Act's definition, the context decides.
- The Special Economic Zones Act reference. Rule 2(d) names another Act and a clause number. Check the current law for the corresponding provision.
- Later notifications. Rules are amended by notification. Check for notifications issued after 31 October 2025 before relying on any rule.

Disclaimer: Based on the Central Goods and Services Tax Rules, 2017 and the GST Acts as amended up to 31 October 2025 in the compilation consulted, read with the Finance Act, 2026 where this article says so, as consulted on 2 October 2026. Notifications, circulars and amendments issued after that date, the forms on the common portal and the way the tax authorities apply these provisions should be checked.
