    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.

⚠️WARNING

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.
