The special proviso has both supplier and transaction conditions
Rule 47’s further proviso addresses an insurer, bank or financial institution including an NBFC, telecom operator, or another notified supplier class making taxable service supplies between section 25 distinct persons. It permits the stated invoicing by reference to recording in books or expiry of the supply quarter. This guide checks the April 2026 bare law on 27 October 2026. It is not a general quarterly invoice permission for every inter-company or inter-branch entry. ICAI April 2026 GST bare law: Rule 47, further proviso.
Establish the parties and an actual taxable service
Confirm the supplier class, registrations and section 25 status. Two different companies are not distinct persons merely because they belong to the same corporate group. Equally, an internal allocation label does not alone prove a taxable service or decide whether another mechanism applies. The examples assume the supply and distinct-person conditions are independently established; they do not decide ISD versus cross-charge or valuation questions. ICAI April 2026 GST bare law: Rule 47, further proviso.
Preserve the wording instead of inventing a universal extension
The proviso states that the invoice may be issued before or at the time the supplier records the supply in its books, or before expiry of the quarter during which supply was made. Keep those event dates and the invoicing basis explicit. Do not convert that wording into a universal forty-five-day extension, an automatic permission to postpone accounting, or a fresh deadline measured from payment receipt. ICAI April 2026 GST bare law: Rule 47, further proviso.
Use a supply-quarter register
Map the actual supply to its quarter and retain the book-recording and invoice timestamps. A batch containing supplies on both sides of a quarter boundary needs a split working. If a proposed invoice lies outside a claimed quarter route, flag it and assess the actual applicable route and facts; do not assume the next quarter’s first day belongs to the preceding quarter. ICAI April 2026 GST bare law: Rule 47, further proviso.
Reconcile invoice populations to the ledger
Compare identified taxable-service values and documents, not every inter-office ledger movement. Maintain exception lists for unbilled items, reversals and different registration pairs. A timing control does not settle tax rates, return reporting or input-credit conditions. The examples illustrate calendar and value checks, with no tax-rate assumptions or claim that all inter-office charges are taxable. ICAI April 2026 GST bare law: Rule 47, further proviso.

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Book-recording route evidence
Assume a qualifying supply on 10 April 2026 is recorded in the supplier’s books and invoiced on 15 May 2026. The elapsed interval is 35 days. Retain evidence of the actual book event and invoice; the example uses that stated route rather than inferring permission solely from a generic thirty-day test.
Illustrative example 2: Map a July supply to its quarter
For an independently qualifying supply made on 1 July 2026, the supply quarter ends 30 September 2026. The calendar interval is 91 days. A quarter-route control should retain that period and the invoice evidence, not replace it with an assumed ninety-day period.
Illustrative example 3: Detect a quarter mismatch
A qualifying supply is made on 30 September 2026. A proposed invoice is dated 1 October 2026, one calendar day later and in the next quarter. It cannot be described as issued before expiry of the July–September quarter. Review the actual invoicing basis and facts rather than declaring that this observation alone decides every possible legal consequence.
Illustrative example 4: Split a cross-quarter batch
A supported ₹10 lakh supply dated 29 June 2026 and a ₹20 lakh supply dated 1 July 2026 belong to different quarters, ending 30 June and 30 September respectively. Their combined ₹30 lakh value does not justify moving the June item into the July quarter’s timing population.
Illustrative example 5: Separate an inter-company entry
Assume the working contains ₹10 lakh and ₹4 lakh of independently qualifying distinct-person services, plus a ₹6 lakh service between separate group companies. The qualifying population is ₹14 lakh, not ₹20 lakh, on those assumed facts. The ₹6 lakh still needs its own applicable invoicing analysis.
Illustrative example 6: Reconcile the book population
The supported qualifying-service ledger is ₹50 lakh and mapped invoices are ₹42 lakh. The ₹8 lakh difference requires an itemised explanation and timing check. It is not automatically tax shortfall or an exempt amount; determine what the unmatched entries actually represent.

Sixteen practitioner FAQs
1. Does every supplier have this quarter-related facility?
No. The proviso identifies supplier classes and a distinct-person service population.
2. Does it expressly mention telecom operators?
Yes, alongside the stated financial-sector suppliers and other notified classes.
3. Can an ordinary manufacturer claim it merely for an inter-branch allocation?
Not without establishing an applicable supplier-class basis and all relevant conditions.
4. Are separate group companies automatically section 25 distinct persons?
No. Do not replace the registration-status enquiry with corporate-group membership.
5. Does a cost-allocation label prove a taxable supply?
No. Analyse the actual transaction and applicable mechanism.
6. Does this guide decide ISD versus cross-charge?
No. The examples assume the invoicing population is independently established.
7. What book evidence should be kept?
The actual recording event and its link to the supply and invoice.
8. Does the proviso authorise arbitrary accounting deferral?
Do not infer such permission from an invoice-timing provision.
9. Is the quarter a fixed ninety days?
No. Actual calendar quarters can have different day counts.
10. Can a June supply be placed in the July quarter merely by batching?
No. Identify the supply’s own quarter and actual invoicing basis.
11. Is 1 October inside the July–September quarter?
No. It is the next quarter’s first day.
12. Does an outside-quarter date alone settle every consequence?
No. Assess the actual route, facts and applicable provisions.
13. Is payment receipt the new universal starting point?
The stated proviso refers to book recording and the supply quarter; do not invent a payment-based rule.
14. Can unmatched ledger value be called tax shortfall automatically?
No. Explain the entries and separately compute the applicable tax result.
15. Does the timing facility waive invoice particulars?
No. Check the applicable document requirements separately.
16. Does correct timing alone establish input-credit eligibility?
No. Apply the independent entitlement conditions.
Conclusion
Apply Rule 47’s distinct-person service-invoicing proviso only to its specified suppliers, keeping supply dates, book entries and quarter evidence separately traceable.
