A Complete Guide to SSIC Code in Singapore

You’re getting ready to register your business, filling in your company name, address, and all the usual details. Then suddenly, this question pops up: “What’s your SSIC code?”

Choosing the right SSIC code can feel more complicated than expected, especially when you just want to get your business registered without sending the wrong signal to ACRA.

This guide explains what an SSIC code is, why it matters, and how to pick the right one without overthinking it.

What is an SSIC Code

An SSIC code, short for Singapore Standard Industrial Classification code, is a five-digit number that tells the government what kind of business activity your company is involved in.

Think of it as Singapore’s official way of categorising businesses. Whether you're running a bakery, building software, or offering pet grooming services, there’s an SSIC code that fits what you do.

What is an SSIC code used for

You’ll need to select an SSIC code when registering your company on ACRA’s BizFile system. But its use goes beyond just registration. Here are the key areas where the SSIC code is required:

• Company registration: You are required to select an SSIC code that accurately reflects your primary business activity during company registration.

• Licensing and permits: Certain business activities, such as operating a restaurant or providing financial advisory services, require specific licenses. The SSIC code enables government agencies to identify these activities and determine if additional approvals or permits are necessary.

• Statistical and policy purposes: Government agencies utilize SSIC codes to analyze industry trends, design support programs, and inform national economic policies.

• Tax matters: The SSIC code declared helps the Inland Revenue Authority of Singapore (IRAS) assess tax obligations and compliance requirements related to your business activities.

Why is an SSIC Code Important?

ACRA, IRAS, and other government agencies rely on the SSIC code to understand, regulate, and support your business. Here is how they use it and why it matters to you.

• ACRA uses the SSIC code you provide during registration to classify your company’s primary business activity and maintain it as part of your official company profile.

• IRAS refers to your SSIC code to determine tax treatment, filing requirements, and whether any industry-specific tax rules apply.

• Sector regulators use the SSIC code to assess whether your business activity requires specific licences or approvals. For example, if you are running a fintech business, the Monetary Authority of Singapore (MAS) uses your SSIC code to determine if you need a financial services licence.

• Many government grants and assistance schemes target specific industries. Having the correct SSIC code ensures your business is properly identified and eligible for these opportunities.

• Your SSIC code appears in official business records, enabling banks, investors, and partners to verify your company’s primary activity and assess credibility accurately.

How to Find the Right SSIC Code for My Business

Finding the right SSIC code can feel overwhelming with so many options out there. To make it easier, follow these practical steps to identify your principal business activity and pick the best code:

Step 1: Use Simple and Relevant Keywords

When searching the SSIC list or the ACRA BizFile portal, start with clear, straightforward keywords that describe your business. Try both specific terms and broader ones if needed. For example, if you run a marketing agency, try keywords like “marketing,” “advertising,” or “digital services.”

Step 2: Browse and Compare Candidate Codes

Review the code descriptions carefully. Sometimes multiple codes may seem to fit, so read their definitions to find the closest match.

Step 3: Select Your Principal SSIC Code

Pick the code that best reflects your primary business activity. This is the main code you will declare when registering your company.

Step 4: Identify Secondary SSIC Codes if Needed

If your business has significant secondary activities, you can also declare additional SSIC codes. These represent other business areas but are secondary to your main operation.

Step 5: Seek Advice if Unsure

If you’re unsure which code fits best, consider consulting a business advisor, accountant, or contacting ACRA directly for guidance.
