How GST Is Calculated

Singapore GST is a broad-based consumption tax levied on most goods and services supplied in Singapore and on goods imported into Singapore. The current rate of 9% took effect on 1 January 2024. GST is charged on the value of the supply and is the same rate regardless of the transaction amount.

Adding GST

GST Amount = Price × 0.09

Total = Price × 1.09

Example: $100 × 1.09 = $109.00

Removing GST

Base Price = Total ÷ 1.09

GST Amount = Total − Base

Example: $109 ÷ 1.09 = $100.00

Miss a deadline and IRAS charges S$200+ — even on nil returns. Sleek handles your quarterly GST filing from S$100/month.

GST Rate History

Singapore introduced GST in 1994 at a low rate to fund long-term government expenditure. The rate has been gradually increased over the years as part of Singapore's fiscal planning, with the most recent increase in January 2024 as announced in Budget 2022.

1 Apr 1994 3% GST introduced in Singapore
1 Jan 2003 4% Rate increased to support fiscal policy
1 Jan 2004 5% Rate increased as announced in Budget 2003
1 Jul 2007 7% Rate increased — stable for 15+ years
1 Jan 2023 8% First step of two-stage increase (Budget 2022)
1 Jan 2024 9% Current rate — second step of two-stage increase

Why was GST raised to 9%? The Singapore government announced in Budget 2022 that GST would be raised in two stages to fund increased healthcare and social spending for an ageing population. An S$6 billion Assurance Package was provided to help Singaporeans offset the additional costs.
