When should a Singapore company register for GST?


GST registration in Singapore is mandatory if a company's annual taxable turnover exceeds S$1 million or if it voluntarily opts for registration. Certain businesses must register regardless of turnover. Benefits include credibility, input tax credit, and global competitiveness. Obligations include charging GST, filing returns, and maintaining records. The registration process involves determining eligibility, submitting documents, and awaiting approval. Voluntary de-registration is possible under specific circumstances.

Goods and Services Tax (GST) is a consumption tax levied on the supply of goods and services in Singapore. Administered by the Inland Revenue Authority of Singapore (IRAS), GST plays a significant role in the country's tax system. For businesses operating in Singapore, understanding when to register for GST is crucial to ensure compliance with tax regulations and to manage financial obligations efficiently.

This article aims to provide a comprehensive overview of GST registration for Singapore companies, including the criteria for registration, benefits, obligations, and the process involved.

  1. Understanding Goods and Services Tax (GST):

Goods and Services Tax (GST) is a broad-based consumption tax imposed on the import of goods as well as nearly all supplies of goods and services in Singapore. The current GST rate in Singapore is 7%, and it is levied on the value of goods and services at each stage of the supply chain.

  1. Criteria for GST Registration:

Singapore companies must register for GST if their annual taxable turnover exceeds or is expected to exceed S$1 million. However, businesses with annual taxable turnover not exceeding S$1 million may also voluntarily register for GST.

Additionally, certain businesses are required to register for GST regardless of their turnover. These include:

  • Businesses making taxable supplies and whose annual turnover from taxable supplies exceeds S$1 million at the end of any calendar quarter;

  • Businesses making zero-rated supplies that qualify for GST refunds;

  • Importers of goods under the Major Exporter Scheme (MES) or the Approved Third-Party Logistics (3PL) Company Scheme;

  • Businesses providing e-commerce services to non-GST registered customers in Singapore;

  • Tourist refund scheme operators.

Understanding these criteria is essential for companies to determine their GST registration obligations accurately.

  1. Benefits of GST Registration:

There are several benefits associated with GST registration for Singapore companies:

  • Credibility: GST registration enhances the credibility of a business, especially for dealings with other registered businesses and government agencies.

  • Input Tax Credit: Registered businesses can claim input tax credit on GST paid on purchases and expenses, thereby reducing the overall tax burden.

  • Global Competitiveness: GST registration can improve a company's competitiveness in the international market by enabling it to compete effectively with businesses from GST-registered countries.

  • Compliance: Registered businesses are required to comply with GST regulations, fostering a culture of transparency and accountability in their operations.

  1. Obligations of GST-Registered Companies:

Once registered for GST, companies must fulfill certain obligations imposed by IRAS. These include:

  • Charging GST: Registered businesses must charge GST on taxable supplies made to customers.

  • Filing GST Returns: Companies are required to file GST returns periodically, typically on a quarterly basis, and remit the GST collected to IRAS.

  • Maintaining Records: GST-registered businesses must maintain proper accounting records, including invoices, receipts, and relevant documents, for at least five years.

  • Compliance with Regulations: Companies must comply with GST regulations and guidelines issued by IRAS, including those related to invoicing, registration, and reporting.

Non-compliance with GST obligations can result in penalties, fines, and other legal consequences, underscoring the importance of adherence to regulatory requirements.

  1. Process of GST Registration:

The process of GST registration for Singapore companies involves several steps:

  • Determine Eligibility: Verify if the company meets the criteria for mandatory or voluntary registration based on its turnover and nature of business activities.

  • Prepare Required Documents: Gather necessary documents, including identification proof, business profile, bank account details, and information about business activities.

  • Submit Application: Complete the GST registration form (Form GST F1) online via IRAS' myTax Portal or through a registered filing agent.

  • Await Approval: IRAS typically processes GST registration applications within 10 working days. Upon approval, the company will receive a GST registration notification.

  • Commence Charging GST: Once registered, the company can start charging GST on taxable supplies made to customers and issue tax invoices accordingly.

It's essential for companies to ensure accuracy and completeness in their GST registration applications to avoid delays or complications in the process.

  1. Voluntary De-registration from GST:

In certain circumstances, a GST-registered company may opt for voluntary de-registration from GST. This could be due to various reasons, such as a significant decrease in turnover, cessation of business operations, or a change in business structure.

The process of voluntary de-registration involves notifying IRAS through the myTax Portal and fulfilling any outstanding GST obligations, including filing of final GST returns and payment of any outstanding tax liabilities. Upon successful de-registration, the company will cease to be GST-registered and must comply with any additional requirements imposed by IRAS.


Goods and Services Tax (GST) registration is a crucial aspect of compliance for Singapore companies engaged in the supply of goods and services. Understanding the criteria, benefits, obligations, and process of GST registration is essential for businesses to navigate the tax system effectively and ensure compliance with regulatory requirements.

By adhering to GST regulations and fulfilling their tax obligations diligently, companies can enhance their credibility, manage their finances efficiently, and contribute to the stability and growth of Singapore's economy. Therefore, it is imperative for businesses to stay informed and seek professional advice when necessary to ensure proper GST compliance.
