Important GST changes are underway in 2019 and 2020. The first wave of changes started in January 2019, with Customer accounting being implemented on the supply of certain prescribed goods by GST-registered suppliers to their GST-registered customers.


With effect from 1st of January 2020, GST will be applied on imported service in the context of business-to-business (“B2B”) transactions by way of a reverse charge mechanism. The taxation of business-to-consumer (“B2C”) transactions will take effect through an Overseas Vendor Registration (“OVR”) mode.


It is critical that organisations start making preparations to ensure that their staff and systems are well-equipped to comply with the new requirements. This workshop will give you a good understanding on the features of the customer accounting, reverse charge mechanism and the related registration and compliance rules.


This comprehensive workshop is designed specifically to provide you with a practical update on the recent GST changes implemented. Practical tips and pointers will be discussed to help your organisation make a seamless transition to implement the GST changes.
