What is GST in Singapore?
Goods and Services Tax (GST) is a consumption tax levied on the supply of goods and services in Singapore, as well as the import of goods. The current standard GST rate is 9%.
Businesses that are GST-registered must:
- Charge GST on taxable supplies (Output Tax)
- Claim GST on business purchases (Input Tax)
- File periodic GST returns (usually quarterly)
- Maintain proper documentation for 5 years
Non-compliance can lead to financial penalties, tax audits, and reputational damage. That’s why professional GST filing services are essential.
