Singapore GST 9%

GST (Goods and Services Tax) is Singapore's consumption tax, run by the Inland Revenue Authority of Singapore (IRAS). The standard rate climbed from 7% to 8% in January 2023, then to 9% in January 2024. How you apply it comes down to whether the price already includes GST or not: Inclusive = Exclusive × 1.09 and Exclusive = Inclusive / 1.09. So an item listed at S$ 100 before GST sells for S$ 109 once GST is added (GST = S$ 9). Going the other way, S$ 109 inclusive breaks down into S$ 9 of GST and S$ 100 of net value. Registering with IRAS is mandatory for businesses whose annual taxable turnover tops S$ 1 million. Stay under that and registration is up to you.

Applications and context

This comes in handy for e-commerce sellers in Singapore, Brazilian exporters chasing the Asian market, cross-border digital services under the Overseas Vendor Registration regime, plus everyday invoicing and price quoting. Since 2023, overseas suppliers selling low-value goods and digital services to consumers in Singapore have to register and charge GST too.

FAQ

Are exports subject to GST? No. Exports of goods and international services are zero-rated (0%), so GST is charged at 0% and you can still claim back the input tax.

What is the threshold for mandatory registration? Taxable turnover that goes past S$ 1 million over a 12-month period.

Will the rate go up again? The 9% rate has held since January 2024 and nothing else has been announced so far. Check with IRAS for the rate that applies right now.
