Many new business owners often wonder, “How long does company GST registration take in Singapore?” The answer depends on various factors such as the accuracy of your application, type of registration, and how well-prepared your documents are.

WZ Wu & Partners is one of the best accounting and tax advisory firms in Singapore, helping businesses navigate complex tax requirements smoothly. In this guide, we’ll explain how long GST registration usually takes, what factors affect the timeline, and how you can speed up the process.

Understanding GST Registration in Singapore

Before diving into the timeline, let’s start with the basics.

GST (Goods and Services Tax) is a consumption tax levied on the supply of goods and services in Singapore and on the import of goods into Singapore. It’s similar to VAT in other countries. The current GST rate stands at 9% (as of 2025).

All businesses with taxable turnover exceeding S$1 million in the past 12 months or expecting to exceed that amount in the next 12 months are required to register for GST with the Inland Revenue Authority of Singapore (IRAS).

Types of GST Registration

There are two main types of GST registration in Singapore:

1. Compulsory Registration

   • Applicable when your business turnover exceeds or is expected to exceed S$1 million.

   • Must apply within 30 days of reaching the threshold.

2. Voluntary Registration

   • For businesses with turnover below S$1 million but wishing to register for GST benefits (like input tax claims).

   • Subject to IRAS approval, often requiring additional documentation.

Each registration type can affect how long the approval process takes.

Average Time for Company GST Registration in Singapore

On average, GST registration in Singapore takes between 10 to 30 working days after submission to IRAS.

Here’s a breakdown of the typical process:

So in total, you can expect about 2 to 4 weeks for the complete process, depending on how complete and accurate your application is.

Factors That Affect GST Registration Timeline

While IRAS strives to process applications efficiently, several factors can impact how long it takes:

1. Accuracy of Information

Incomplete or incorrect details in the application can delay approval. Double-check all entries before submission.

2. Type of Registration

Voluntary registrations often take longer because IRAS needs to ensure the company genuinely engages in taxable business activities.

3. Supporting Documents

If your business is newly incorporated or lacks a clear operational history, IRAS may request additional documents such as invoices, contracts, or business plans.

4. IRAS Query Response Time

Delays often occur if businesses take too long to respond to IRAS requests for clarification. Prompt replies help shorten processing time.

5. Use of a Professional Firm

Engaging experienced professionals like WZ Wu & Partners can significantly speed up the process by ensuring your application meets all IRAS requirements the first time.

Documents Required for GST Registration

Having the right documents ready is crucial. Typically, you’ll need:

• A copy of the ACRA business profile

• Recent financial statements or sales invoices

• Bank statements (to show business transactions)

• Contracts or agreements with suppliers/customers

• Projected sales and expenses for the next 12 months

• Particulars of directors and shareholders

Providing these upfront ensures a smoother review by IRAS.

How to Apply for GST Registration

Here’s a step-by-step overview of the process:

Step 1: Determine Your Eligibility

Check whether your company needs compulsory registration or qualifies for voluntary registration.

Step 2: Prepare Required Documents

Gather the documents listed above. Accuracy and completeness are key.

Step 3: Submit via MyTax Portal

Log in to MyTax Portal using your CorpPass credentials and fill out the GST F1 form (for businesses).

Step 4: Await IRAS Review

IRAS will assess your application. If additional details are needed, you’ll receive a request via the portal or email.

Step 5: Receive GST Registration Number

Once approved, IRAS will issue your GST registration letter, indicating your GST number and effective registration date.
