Understanding GST in Singapore (2025 Update)

Goods and Services Tax (GST) is a significant aspect of Singapore's tax system. As of 2025, several updates and changes have been implemented to enhance the GST framework. Below is an overview of the key elements of GST in Singapore.

What is GST?

Goods and Services Tax (GST) is a consumption tax levied on most goods and services in Singapore. It is administered by the Inland Revenue Authority of Singapore (IRAS) and applies to both local sales and imported goods.

Current GST Rate

The current GST rate is 9% (from 1 January 2024).

When Do You Need to Register for GST?

You must register for GST if your:

• Past 12-month taxable turnover exceeds S$1 million, or

• Expected turnover will exceed S$1 million in the next 12 months.

In addition, businesses may also choose to register voluntarily even if they do not meet the compulsory threshold — for example, to claim input tax credits on business purchases or to enhance business credibility with clients and suppliers.

Common GST Mistakes to Avoid

• Failing to register on time

• Claiming input tax without valid tax invoices

• Charging GST before registration is approved

• Not filing nil returns when there are no transactions

• Incorrect classification of exempt or zero-rated supplies

Filing and Payment

GST returns (Form F5) must be filed quarterly within one month after the end of each accounting period.
