What is GST?
Goods and Services Tax (GST) is a broad-based consumption tax levied on the import of goods, as well as nearly all supplies of goods and services in Singapore. The current rate is 9% (increased from 8% on 1 January 2024). It is equivalent to VAT in many other countries.
Who needs to register?
You must register for GST if your taxable turnover exceeds $1 million in a 12-month period (retrospective basis) or is expected to exceed $1 million (prospective basis). Voluntary registration is also available, but you must remain registered for at least 2 years.
GST Returns
GST-registered businesses must file GST returns (GST F5) quarterly. You report output tax (GST charged on sales) and input tax (GST paid on purchases). The net GST is payable to or refundable by IRAS. Returns must be filed within one month after the end of each accounting period.
IRAS-Aligned: Singapore GST rate is 9% effective 1 January 2024. Some supplies are zero-rated (exports) or exempt (financial services, residential property sales/rentals).
