How it works
How to calculate GST in Singapore
GST in Singapore is 9% of the price before GST. To add it, multiply by 1.09. To take it out of a price that includes it, divide by 1.09: the result is the price before GST, and the difference is the GST.
The GST inside a GST-inclusive price is 9/109 of it, about 8.26%. Taking 9% of the total is the most common mistake: it gives too much, because the 9% was added to the smaller price before GST.
The calculator above also handles what a fixed 9% can’t: sales from overseas sellers, GST-registered business customers who are reverse-charged, and products that are zero-rated or exempt.
S$100.00× 1.09S$109.00
GST: S$9.00
S$109.00÷ 1.09S$100.00
GST: S$109.00 − S$100.00 = S$9.00
S$54.50× 9 ÷ 109S$4.50
That’s 9/109 of the price, about 8.26%.

Restaurants and hotels
Service charge and GST
Restaurants, bars and hotels usually add a 10% service charge, and GST is charged on top of it: on the price plus the service charge. So the bill is the menu price × 1.10 × 1.09, or × 1.199 in one step.
To go back from a bill to the menu price, divide by 1.199. Places that add a service charge may show menu prices before service charge and GST, with a notice saying so. Other businesses must show prices with GST included.
| Menu price | Service charge (10%) | GST (9%) | Total |
|---|---|---|---|
| S$20.00 | S$2.00 | S$1.98 | S$23.98 |
| S$50.00 | S$5.00 | S$4.95 | S$59.95 |
| S$80.00 | S$8.00 | S$7.92 | S$95.92 |
| S$100.00 | S$10.00 | S$9.90 | S$119.90 |
| S$200.00 | S$20.00 | S$19.80 | S$239.80 |
Who charges GST
When GST is charged, and when it isn’t
GST-registered businesses charge 9%. Registering is compulsory once taxable turnover passes S$1,000,000 a year. How GST registration works.

FAQ
Singapore GST calculator FAQ
What is the GST rate in Singapore?
9%, since 1 January 2024. It was 8% in 2023 and 7% before that. There are no reduced rates: everything that’s taxed is taxed at 9%, and exports are zero-rated.
How do I add GST to a price?
Multiply the price before GST by 1.09. On S$200.00, the total is S$218.00 and the GST is S$18.00.
How do I remove GST from a price?
Divide the GST-inclusive price by 1.09. On S$54.50, the price before GST is S$50.00 and the GST is S$4.50. Don’t take 9% off the total: that gives too much.
How is GST calculated with a service charge?
The service charge is added first, then GST is charged on the price plus the service charge. With a 10% service charge, multiply the menu price by 1.199: a bill of S$80.00 comes to S$95.92.
Do I charge GST to customers outside Singapore?
No. Goods you export, and most services for overseas clients, are zero-rated: you charge 0% GST and keep proof of the export. Your customer may owe their own country’s tax instead.
Do overseas businesses charge Singapore GST?
Once they register under the Overseas Vendor Registration regime: when their global turnover is over S$1,000,000 and their sales of digital services, remote services and low-value goods to Singapore consumers are over S$100,000 a year. Set the seller to another country in the calculator to see how a sale from overseas is taxed.
