GST registration
A Singapore business must register for Goods and Services Tax (GST) with IRAS when its taxable turnover exceeds S$1 million in a year, and can choose to register below that.
GST is Singapore's consumption tax, charged at 9% since 1 January 2024. Registration is compulsory when a business's taxable turnover was more than S$1 million in the past 12 months, or is expected to be more than S$1 million in the next 12 months. Smaller businesses can register voluntarily.
GST-registered businesses have a GST registration number, which for most companies is the same as their UEN.
Why it matters in sales: GST registration is a rough signal that a business has crossed S$1 million in turnover. You can check a business's GST status on the IRAS website.
