Retitled for Singapore import GST orientation; kept the S$ million registration threshold framing and stressed confirmation with IRAS.
📋 Direct Answer
Singapore GST registration follows IRAS taxable-turnover tests. Register for GST if taxable turnover is more than SGD 1000000 at the end of the calendar year (confirm dual tests on IRAS). Do not apply EU VAT OSS thresholds to Singapore GST.
Late GST registration in Singapore triggers retrospective GST liability and penalties from IRAS
IRAS may backdate GST liability to when the threshold was exceeded, impose penalties up to % of the tax amount, and charge late payment penalties of % per month
🛡️ Prevention Steps
- ✓Monitor taxable turnover monthly — the retrospective liability can be significant
- ✓Register within days of exceeding the threshold
- ✓If you expect to exceed the threshold in the next months, register proactively
Common Mistakes
❌ Treating GST as optional once you are clearly over the local S$ million test
💥 Consequence: Penalties if you should have registered for standard GST
✅ Fix: Use the IRAS -month S$ million taxable-turnover test for local/standard GST
❌ Registering for OVR just because you made any sale to a Singapore consumer
💥 Consequence: Wrong scheme or unnecessary registration; or missing OVR when both tests are met
✅ Fix: OVR uses a dual threshold (commonly global S$ m and SG remote B C S$ k). Confirm on IRAS.
