- The GST Registration Trap
The GST Registration Trap#
A Singapore online retailer hits SGD 1M turnover. Owner doesn't realize GST registration is now mandatory. Continues operating unregistered. IRAS (Inland Revenue Authority) audits 6 months later. Back-GST owed: SGD 70K (7% of SGD 1M). Penalties: SGD 1K-5K. Interest: SGD 3K+. Total: SGD 74K+. Could have avoided by registering on time.
What Triggers Mandatory Registration?#
(1) Turnover exceeds SGD 1M in any 12-month period. (2) Supplies to another GST-registered business. (3) Imports goods above certain value. Most common: turnover threshold.
