The Goods and Services Tax (GST) rate in Singapore is 9% from 1 January 2024. This calculator uses 9% by default, and you can change the rate if needed.
To remove 9% GST from a GST-inclusive price, divide the total by 1.09. The result is the amount before GST. The GST portion is the difference between the total and the pre-GST amount.
Singapore uses a 9% Goods and Services Tax (GST) that applies broadly across the supply chain with input tax credits. Malaysia uses a Sales and Service Tax (SST), with the service tax rate at 8% on many services. They work differently, so this tool offers a simple side by side comparison only.

Goods and Services Tax (GST) is a broad-based consumption tax charged on most goods and services in Singapore. Since 1 January 2024 the rate has been 9%. This calculator handles the two situations people meet most often. Adding GST takes a pre-tax amount and shows the tax and the final price. Removing GST takes a tax-inclusive price and works backwards to show the amount before tax and the GST portion.
To add GST, multiply the net amount by the rate. At 9%, a net price of S$100 carries S$9 of GST, for a total of S$109. Businesses display GST-inclusive prices to consumers, so the figure you pay at the counter already has GST built in.
To remove GST from a tax-inclusive total, divide by 1 plus the rate. At 9%, divide the total by 1.09. For a S$109 receipt, the amount before GST is S$100 and the GST portion is S$9. This is useful when you need the pre-tax figure for accounting or expense claims.
Singapore uses GST while Malaysia uses a Sales and Service Tax (SST), with the service tax at 8% on many services. The two systems are structured differently. GST applies across the supply chain with input tax credits, while SST is narrower. The comparison here simply applies both rates to the same amount so you can see the headline difference. It is not a full tax analysis.
