Goods & Services Tax (GST)

GST is a tax on domestic consumption. It is levied on nearly all supplies of goods and services in Singapore, as well as import of goods into Singapore. GST is charged at 7% for standard-rated supplies. If your company has a taxable turnover of over S$1 million in a calendar year, you have to register for GST and comply with the filing requirements. There are scenarios where you may opt to register for GST voluntarily for business reasons, even though your business does not exceed S$1 million.

We provide a comprehensive range of GST services including GST registration and filing of quarterly  GST return.
