Your Ultimate Guide to GST Registration in Singapore (2025 Edition)

Goods and Services Tax (GST) in Singapore is a broad-based consumption tax levied on nearly all supplies of goods and services as well as imports. Similar to VAT in other countries, GST plays a crucial role in Singapore’s tax framework.

As of 1 January 2024, the GST rate in Singapore is 9%.

If you are starting or running a business in Singapore, understanding GST Registration requirements is essential for compliance and long-term growth. At JSE Offices, we specialize in helping businesses navigate the complexities of GST registration with ease and efficiency.

Why GST Registration Matters for Your Business

GST registration is not just a regulatory requirement — it is also a signal of legitimacy and operational scale. Registered businesses can charge and collect GST, claim input tax, and are seen as credible partners in B2B transactions.

Key Benefits of GST Registration:

• Claim Input Tax Credits on business purchases

• Legally collect GST from customers

• Enhance business credibility with vendors and clients

• Facilitate compliance and avoid penalties

Who Needs to Register for GST in Singapore?

1. Compulsory Registration

You must register for GST if:

• Your taxable turnover exceeds SGD 1 million over the past 12 months (retrospective basis), or

• You expect your taxable turnover to exceed SGD 1 million in the next 12 months (prospective basis)

Failing to register on time can result in penalties, backdated GST payments, and loss of business credibility.

2. Voluntary Registration

You can voluntarily register for GST even if your turnover does not exceed SGD 1 million. This is common for businesses dealing with GST-registered clients or importing/exporting goods and services.

However, once voluntarily registered, you must comply with all GST obligations for at least two years.

GST Registration Process in Singapore

At JSE Offices, we handle the GST registration process from start to finish. Here’s a step-by-step breakdown:

Step 1: Assess Eligibility

We evaluate your business turnover, nature of supplies, and projected income to determine whether registration is required or beneficial.

Step 2: Prepare Documents

You’ll need to provide:

• ACRA business profile

• Identity details of owners/directors

• Bank account info

• Past 12 months’ sales records (if applicable)

• Forecasted income (for prospective registration)

Step 3: Submit GST Registration Application

The application is submitted online through IRAS’ myTax Portal. We ensure all the documents are complete and your submission meets IRAS requirements.

Step 4: Receive GST Number

IRAS usually processes applications within 10 working days, but it may take longer if further clarification is needed.

Once approved, you’ll receive a GST Registration Letter with your GST Registration Number and effective date.

Your GST Compliance Obligations

Once registered, businesses must:

1. Charge GST on Sales

This is known as output tax, which must be clearly stated on invoices.

2. Claim GST on Purchases

Also known as input tax, this can be deducted from output tax before payment to IRAS.

3. File GST Returns

GST returns (Form F5) are typically filed quarterly, but can also be monthly or half-yearly depending on the business. You must file returns even if there is no GST transaction during the period.

4. Pay GST Due

Any net GST owed to IRAS must be paid by the due date (usually one month after the end of the accounting period).

5. Keep Proper Records

Businesses are required to retain accounting and tax records for at least 5 years.

2. What is taxable turnover?

Taxable turnover includes all sales of goods and services that are subject to GST, excluding exempt supplies such as financial services or sale/lease of residential properties.

Typically, IRAS takes about 10 working days to process the application, but this may be extended if additional information is required.
