A proposed earlier date calls for a separate response
Clause 4 of Notification No. 05/2026–Central Tax substitutes Rule 20 from 1 November 2026. Sub-rules (14)–(20) set out how a proper officer may propose an earlier effective date after cancellation under that rule. Clauses 44–47 separately insert the four prescribed forms from 1 April 2027: GST REG-34 for the notice, REG-35 for the reply, REG-36 for dropping or deemed dropping, and REG-37 for an order changing the effective date. A notice alone does not change the date.
Read the applicable text: Gazette text: Notification 05/2026–Central Tax, clauses 4 and 44–47; CGST Act, 2017: sections 29 and 169.
These are separate commencement dates. The November substitution does not establish that the four forms were already prescribed or available on the portal in November. If a notice or portal instruction is received before 1 April 2027, verify its legal basis and the applicable response route promptly; do not ignore it or assume that the April forms are already in use.
Maintain two notice clocks
Rule 20(15) gives 30 days from receipt to furnish the reply. Sub-rules (16) and (17) give 30 days from receipt of the reply for the officer to drop proceedings or issue a change order as applicable. Sub-rule (18), dealing with no reply, refers to 30 days from issuance and gives a 60-day period from issuance for a change order. Sub-rule (19) provides for deemed dropping if no order is issued within 60 days of issuance. Because the texts use different triggers, capture issuance, receipt and reply receipt independently. Where they create a timing dispute, act promptly and preserve the service evidence instead of assuming the earlier clock defeats a timely reply or that the clocks can simply be added together.
Prove the relevant date with transaction evidence
Compare the original REG-16 and cancellation communication or order with the proposed date and stated grounds. Prepare a period-by-period file from the proposed date through the day before the original effective date. Include invoices, credit notes, stock and capital goods records, returns, payment trails and corroboration of when the business or relevant activity stopped. Address each reason in the notice and explain gaps or apparently conflicting activity. Preserve evidence of service under section 169 and check the hearing details shown in the prescribed REG-34 where applicable.
Separate order status from liability consequences
Section 29(3) preserves pre-cancellation liabilities and obligations. Review stock consequences under section 29(5) and transaction-level impacts separately where relevant; a spreadsheet of invoices in the disputed interval does not itself prove liability or establish recipient ITC treatment. Under Rule 20(20), the effective date once changed under this rule is not subject to further change under that procedure. Preserve the final form and obtain case-specific review where the date or other consequences are disputed.
Six worked illustrations
All facts and amounts are fictional. Calculations illustrate the stated assumptions, not a predetermined legal outcome.
Illustrative example 1: Reply and no-order checkpoints
Assume REG-34 is issued 5 May 2027 and received 8 May. Excluding the trigger date for this illustration, 30 days from receipt gives 7 June 2027; 60 days from issuance gives 4 July 2027. Verify legally applicable service, counting and portal dates.
Illustrative example 2: Early reply
Using the notice in example 1, assume the officer receives the REG-35 reply on 20 May 2027. Adding 30 days gives 19 June 2027. Track that separately from the 4 July issuance-based checkpoint.
Illustrative example 3: Two bases for the dates
A notice issued 6 May 2027 is received 12 May. Adding 30 days gives 5 June from issuance and 11 June from receipt. The six-day gap explains why both records must be preserved.
Illustrative example 4: Affected dates
After a cancellation effective 1 June 2027, the notice proposes moving the date to 11 May 2027. The affected interval is 11–31 May inclusive, 21 days.
Illustrative example 5: Invoice evidence gap
Of ₹18 lakh invoices in the affected interval, ₹13 lakh reconcile to e-way bills or dispatch evidence and ₹3 lakh to service records. The remaining ₹2 lakh needs evidence; this is an exception value, not a tax demand.
Illustrative example 6: Stock snapshot difference
The stock working lists 240 units on the day before the proposed date and 185 before the original date. Reconcile the 55-unit movement before applying any separate statutory stock calculation.

Sixteen practitioner FAQs
1. Does REG-34 itself change the cancellation date?
No. It communicates the proposal and calls for a response.
2. Which form contains the taxpayer's reply?
REG-35 under Rule 20(15).

The rule substitution took effect on 1 November 2026. The notification separately inserts Forms GST REG-34 to REG-37 from 1 April 2027.
4. What begins the ordinary reply clock?
Receipt of the notice under sub-rule (15).
5. Why also keep the issuance date?
The no-reply and deemed-drop provisions refer to issuance.

No. Identify and apply each independent trigger.
7. What form drops proceedings after a satisfactory reply?
REG-36 under Rule 20(16).
8. What if no order is issued within 60 days of issuance?
Sub-rule (19) deems proceedings dropped and provides for REG-36 communication.
9. Which form changes the date?

10. Can a later repeat change be made under this rule?
Sub-rule (20) bars further change once the effective date is changed under the rule.

Use dispatch or service records, invoices, payments and return evidence together.
13. What if records show credit notes after closure?

No. This procedure concerns the effective date of a cancellation already made under Rule 20.
16. What if a portal date conflicts with the served form?
Preserve both timestamps, confirm service under section 169, and seek prompt review of the applicable deadline or submission route.
