The Singapore GST (Goods and Services Tax) calculator helps businesses and consumers determine the GST component of a transaction or add GST to a net price to arrive at the final inclusive price. Singapore's GST is a broad-based consumption tax levied on almost all goods and services supplied in Singapore, and on imports. The GST rate increased to 9% on 1 January 2024, up from 8% in 2023 and 7% before 2023. This makes accurate GST calculation essential for businesses issuing tax invoices and consumers understanding pricing. There are three GST categories: standard-rated (9%), zero-rated (0%), and exempt. Standard-rated supplies include most goods, services, and imports consumed in Singapore. Zero-rated supplies include exports of goods, international services, and supplies to overseas customers — these are taxed at 0% so businesses can claim input tax credits without charging output tax. Exempt supplies include financial services, sale or lease of residential properties, investment precious metals, and importation of investment precious metals. GST-registered businesses with annual taxable turnover exceeding $1 million must register for GST and file quarterly returns with IRAS. Voluntary registration is possible for smaller businesses. As a registered business, you collect GST on sales (output tax) and can offset GST paid on purchases (input tax), remitting only the difference to IRAS. The calculator helps both consumers (to understand the GST component of any price) and businesses (to price their services correctly at 9%).
GST Amount = Net Price × 0.09; Price Including GST = Net Price × 1.09; Net Price from Inclusive = Inclusive Price / 1.09; GST Component from Inclusive = Inclusive Price - (Inclusive Price / 1.09)
- 1Determine whether the supply is standard-rated (9%), zero-rated (0%), or exempt (no GST).
- 2For standard-rated supplies: multiply the net price by 9% to find the GST amount.
- 3Add the GST to the net price to get the total GST-inclusive price for invoicing.
- 4To extract GST from an inclusive price: divide the inclusive price by 1.09 to get the net price, then subtract.
- 5For zero-rated supplies, charge 0% GST but still file GST returns and can claim input tax credits.
- 6For exempt supplies, do not charge GST and cannot claim input tax credits on related expenses.
- 7File quarterly GST F5 returns with IRAS declaring output tax collected and input tax claimable.
Standard rate 9% from January 2024
A Singapore GST-registered professional must charge $900 GST on a $10,000 service. The client pays $10,900 total; the business remits $900 (less input credits) to IRAS.
54.50 / 1.09 = 50.00
When a price tag includes GST, divide by 1.09 to find the pre-GST net. The $4.50 GST is collected by the retailer and remitted to IRAS.
Zero-rated but still GST-registered business claims input tax
Exports are zero-rated. The exporter charges no GST but can reclaim input GST paid on raw materials and services used to produce the exported goods.
Residential rent is GST-exempt
Residential rental is exempt from GST. Unlike zero-rated, the landlord cannot claim input GST on property renovation or maintenance costs as input tax credits.

Pro Tip
If you are a consumer checking whether a price includes GST, look for 'GST-inclusive' or the '+GST' notation on price tags and invoices. All prices advertised to consumers in Singapore must be GST-inclusive. If you see a price marked '+9% GST', the headline amount does not yet include tax.
Did you know?
Singapore's GST was introduced on 1 April 1994 at a rate of just 3%. It has risen gradually over 30 years to the current 9%. Despite the increases, Singapore still has one of the lowest GST rates among developed economies — far below the EU average VAT of around 21% — and the government offsets the impact on lower-income households through permanent GST Voucher cash payouts.
