What this means: A net amount of S$100 with 9% GST added comes to S$109. The S$9 GST is collected by the seller and paid to IRAS.

Only GST-registered businesses, those with annual taxable turnover above SGD 1 million, can charge GST. If a small trader adds GST without a GST registration number on the invoice, that is worth questioning.

How the GST Calculator Works

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.

Adding GST

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.

Removing GST

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.

GST vs SST

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.
