What is the current Singapore GST rate?

The current rate is 9%, effective from 1 January 2024. It was raised from 8% (which itself replaced the previous 7% rate on 1 January 2023).

What is the difference between "Add GST" and "Extract GST"?

"Add GST" (exclusive mode) takes a net price and adds 9% on top: Gross = Net × 1.09. "Extract GST" (inclusive mode) takes a gross price that already includes GST and splits out the tax component: GST = Gross × (9/109).

How do I calculate 9% GST manually?

To add: multiply the net amount by 0.09 to get the GST, then add it to the net. To extract: divide the gross amount by 1.09 — the result is the net price, and the difference is the GST.

Who needs to charge GST in Singapore?

Businesses with a taxable turnover exceeding SGD 1 million per year must register for GST and charge it on their sales. Voluntary registration is also permitted.

Are all goods and services subject to GST?

Most goods and services supplied in Singapore are subject to GST. Notable zero-rated supplies (0% GST) include exported goods and international services. Some items such as residential property sales and financial services are exempt.
