Singapore’s Goods and Services Tax (GST) is an essential part of running a business. Whether you're a start-up or an established enterprise, understanding how GST filing works can help you stay compliant and avoid penalties.
In this guide, we will break down everything you need to know about GST filing Singapore, including who needs to register, filing procedures, and how professional help like bookkeeping services Singapore and outsource accounting Singapore can ease the process.
What is GST in Singapore?
GST is a consumption tax levied on the supply of goods and services in Singapore and the import of goods into the country. It is similar to VAT (Value-Added Tax) in many other countries.
As of 2025, the GST rate in Singapore is 9%. Businesses that are registered for GST must collect this tax from customers and remit it to the Inland Revenue Authority of Singapore (IRAS).
Who Needs to Register for GST?
Your business must register for GST if:
Your taxable turnover exceeds S$1 million in the past 12 months (retrospective basis), or
You expect to exceed S$1 million in the next 12 months (prospective basis)
Voluntary registration is also available for businesses below the threshold, but it comes with responsibilities such as regular filing and accurate record-keeping.
Understanding the GST Filing Process
Once registered, GST-registered businesses are required to:
Charge GST on taxable goods and services
File GST returns (Form F5) every quarter
Pay any GST owed to IRAS
Keep proper documentation to support transactions
Filing deadlines are usually one month after the end of the accounting period. Late filing or payment can result in fines or penalties.
Key Documents Needed for GST Filing
To complete your GST filing accurately, you will need:
Tax invoices and receipts
Purchase orders and supplier invoices
Import/export permits
Credit and debit notes
Bank statements
This is where bookkeeping services in Singapore becomes valuable. These services ensure that all financial records are maintained accurately and consistently, making the GST filing process smoother and more reliable.
