Frequently Asked Questions
Q: What is GST?
A: GST (Goods and Services Tax) is a consumption tax levied on the supply of goods and services in Singapore, as well as on the importation of goods. For 2021, the standard GST rate is 7%. It is a multi-stage tax collected at each stage of production and distribution.
Q: Who must charge GST in Singapore?
A: Businesses with annual taxable turnover of SGD 1 million or more must register for GST with IRAS. Once registered, they must charge GST on all taxable supplies (standard-rated and zero-rated). Businesses below this threshold may apply for voluntary registration.
Q: How is GST calculated?
A: For GST-exclusive prices: GST Amount = Price × 7%, Total = Price + GST. For GST-inclusive prices: GST Amount = Total Price × (7/107), Net Price = Total Price ÷ 1.07. The calculator automatically handles both scenarios.
Q: What is zero-rated GST?
A: Zero-rated supplies are taxable supplies charged at 0% GST. This includes exports of goods and international services. Businesses can claim input tax credits on purchases related to zero-rated supplies, unlike exempt supplies.
Q: What's the difference between GST-inclusive and GST-exclusive pricing?
A: GST-exclusive pricing shows the net price before GST is added. GST-inclusive pricing shows the total price with GST already included. B2C businesses often display GST-inclusive prices, while B2B transactions typically use GST-exclusive pricing.
Q: Can businesses claim input GST?
A: Yes, GST-registered businesses can claim input tax (GST paid on purchases) for business expenses related to taxable supplies. However, input tax on exempt supplies, private/personal expenses, and certain blocked items (e.g., motor cars) cannot be claimed.
Q: When did the GST rate change from 7%?
A: The GST rate was 7% from 2007 to 2023. It increased to 8% on 1 January 2023, and further to 9% on 1 January 2024. This calculator reflects the 2021 rate of 7%.
