Worked examples — five live scenarios

Example 1 — Pre-grant supplies in first return

Facts: Taxpayer became liable 1-Aug-2025. Applied 25-Aug-2025. Grant 5-Sep-2025. Supplies made Rs. 10 lakh during 1-Aug to 4-Sep.

Analysis: Pre-grant period 1-Aug to 4-Sep. Revised invoices to recipients under s. 31(3)(a) within 1 month of grant. Declare supplies in first GSTR-3B (Aug / Sep) under s. 40. Tax + interest payable.

Result: Comprehensive framework operative.

Example 2 — Voluntary registration

Facts: Voluntary registration. Grant 1-Sep-2025. No pre-grant supplies (because no liability-date predates application).

Analysis: Section 40 does not engage. No pre-grant period in operative sense. Standard first return from grant date.

Result: Section 40 not engaged.

Example 3 — Delayed application

Facts: Threshold breach 1-Jun-2025. Application 15-Aug-2025 (75 days late). Grant 1-Sep-2025.

Analysis: Pre-FA 2018 framework — effective registration from application date (post-FA 2018 framework). Pre-grant period 15-Aug to 31-Aug. Pre-application supplies (1-Jun to 14-Aug) — non-registered supplies, separate framework (s. 122 penalty + recovery). Section 40 covers pre-grant supplies only.

Result: Coordinated framework with broader recovery.

Example 4 — Recipient ITC enabling

Facts: Recipient procured from supplier during supplier's pre-grant period.

Analysis: Supplier's revised invoice + first return declaration enables recipient ITC. Section 16(2)(aa) coordination. Practitioner advice — supplier-recipient coordination for ITC framework.

Result: Coordinated framework enables recipient ITC.

Example 5 — Late first return

Facts: Pre-grant supplies declared in first GSTR-3B filed late.

Analysis: Section 47 late fee + s. 50 interest. Bharati Airtel substance-over-form — substantive reporting + tax payment. Documentary trail for audit defence.

Result: Coordinated framework with late fee + interest.
