Singapore GST Calculator
Calculate 9% GST for Singapore (effective 1 Jan 2024). Add GST to a price or remove GST from a GST-inclusive amount.
What is Singapore GST?
Goods and Services Tax (GST) is a broad-based consumption tax levied on the import of goods and most supplies of goods and services in Singapore. Administered by the Inland Revenue Authority of Singapore (IRAS), GST is similar to the Value Added Tax (VAT) used in many other countries. Businesses with an annual taxable turnover exceeding S$1 million must register for GST and charge it on their sales.
Effective 1 January 2024, Singapore's GST rate increased to 9%, completing a two-step hike announced in Budget 2022. The government also introduced an enhanced Assurance Package to help Singaporeans offset the impact of the increase. Understanding how to calculate GST — both adding it to a price and extracting it from a GST-inclusive amount — is essential for business owners, consumers, and anyone filing expense claims.
How to Use the GST Calculator

Add GST formula: GST Amount = Amount × 9%, Total = Amount + GST Amount
