Key takeaways
- Fix the tax period before searching so the current text is not applied automatically to an old year.
- Use the Gazette and official CBIC document as authority, not a search-result snippet or secondary summary.
- Record number, date, effective date, page and exact proposition in a research table.
- A GST Council recommendation is not itself a notified legal change.
- Search again for later amendments, rescission, clarification and judicial status.
Step 1: frame the research question
Write the tax, issue, transaction date, financial year and proposition you need to prove. “Latest ITC rule” is too vague; “ordinary invoice-level section 16(4) deadline for FY 2022–23” is testable.
Step 2: open the statutory provision
Use India Code or the official CBIC material to identify the current provision. Note amendment footnotes and commencement information. If the matter is historical, locate the version that governed the relevant event rather than quoting only today’s consolidation.
Step 3: trace the amending instrument
Identify the Finance Act or other amending Act and the notification that brought the change into force where required. Open the Gazette PDF. Record the exact amending language and its commencement date.
Step 4: locate official circulars and notifications
Search CBIC using the exact document number, year and subject. Confirm whether the document concerns Central Tax, Integrated Tax, rate, customs or another series. Similar numbers in different series are not interchangeable.
Capture a research row:
| Field | Example of what to record |
|---|---|
| Document | Circular/Notification number and series |
| Date | Issue date |
| Authority | CBIC/Department of Revenue/Gazette |
| Effective date | Express date or commencement mechanism |
| Support | Page, paragraph, table entry or proviso |
| Status | Current, amended, rescinded, stayed or uncertain |
| Proposition | The exact sentence the source proves |
Step 5: separate recommendations from law
GST Council releases are valuable for understanding policy and planned changes. Do not describe a recommendation as operative law unless the necessary Act, rule or notification has followed and become effective.
Step 6: run a later-document search
Search the number and subject again with terms such as amendment, rescission, clarification, corrigendum and judgment. Check whether a later circular changes the administration’s position or a court has interpreted the provision differently.
Step 7: cite for verification
In a working paper, link the official document and include the exact page or paragraph. In a reply, quote only what is necessary and explain how it applies to the facts. Keep a copy of the source used so the reviewer can reproduce the conclusion even if a web page later moves.
Using AI safely
Ask AI to return primary-source candidates and mark uncertainty. Require it to distinguish source text from inference and to state the applicable period. Then open every link. A fabricated notification number can look plausible, and a genuine circular can still be irrelevant to the proposition.
TaxByKK is designed to bring this document workflow into supported AI assistants with page-linked sources, but the verification method remains the same.

Frequently asked questions
Where should I search for a CBIC GST circular?
Use the official CBIC GST or tax-information portal and search by the exact circular number and date. Open the original PDF rather than relying on a search snippet.
Is a GST Council recommendation law?
A recommendation signals policy but ordinarily requires the relevant legislative or notified instrument before it changes the operative rule.
How do I cite a GST notification?
Record the notification number, tax, date, issuing authority, Gazette or official URL, effective date and the exact page or entry supporting the proposition.
Can AI find amendments reliably?
AI can accelerate discovery and comparison when connected to sources, but the user must verify identity, effective date, later changes and the supporting passage.
