The upcoming implementation of GST InvoiceNow will fundamentally change how GST-registered businesses report transaction data to IRAS. As invoice information becomes increasingly transparent and submitted through digital channels, organisations will need to ensure that their GST processes, data integrity and control frameworks are fit for purpose in a more connected compliance environment.
This practical workshop provides participants with a clear understanding of the GST InvoiceNow landscape and the key considerations for implementation readiness. Beyond the technology aspects, the session will focus on the underlying fundamentals that support accurate GST reporting, including transaction mapping, data governance, system configuration and internal controls.
Participants will gain insights into common GST risk areas that organisations encounter, such as GST classification errors, time-of-supply issues, input tax recovery challenges, deficiencies in supporting documentation and the growing use of data analytics by tax authorities. Through practical examples and discussions, attendees will learn how to strengthen governance frameworks, improve GST data quality and establish robust controls that can support sustainable compliance in a digital tax environment.
By the end of the workshop, participants will be better equipped to evaluate their organisation’s readiness for GST InvoiceNow, identify potential gaps in GST reporting processes, and enhance the reliability of their GST data, systems and controls.
