My client engaged a contractor who issued non-GST invoices for the period October 2025 to February 2026. In March 2026, the contractor obtained GST registration and subsequently raised GST-compliant invoices covering the entire period from October 2025 to March 2026. Given that no formal contract exists between my client and the contractor, I seek guidance on how my client can avoid liability for GST payment in respect of the period (October 2025 to March 2026).
