Choosing Your SSIC Code: How to Classify Your Business in Singapore Correctly

Introduction

Choosing the correct SSIC code is a fundamental step when registering or updating your company in Singapore. The article “Choosing Your SSIC Code: How to Classify Your Business in Singapore Correctly” explains why the right classification matters for ACRA and IRAS records, GST registration, and other compliance obligations.

Many business owners overlook the Singapore Standard Industrial Classification (SSIC) when completing the ACRA BizFile+ registration or when updating business activities in later filings. This guide outlines the rules, steps and practical tips to select the appropriate SSIC code.

Who this applies to

This guidance is relevant to:

• Entrepreneurs incorporating a company in Singapore using the ACRA BizFile+ portal.
• Existing companies reviewing their registered activities for IRAS GST registration, licences or permits.
• Corporate secretaries, accountants and advisers preparing filings or supporting compliance.
• Foreign entities registering branches or representative offices and needing to declare business activities.

Key rules and requirements in Singapore

Understanding the regulatory context will help you select the correct SSIC code.

• ACRA requirement: Companies must state their principal activities on incorporation and keep these records up to date. The Companies Act requires accurate company particulars on file.
• IRAS linkage: IRAS uses SSIC codes when assessing tax matters, GST registration thresholds and industry statistics. An incorrect code can affect GST classification and tax treatment.
• Licences and permits: Government agencies (MOM, NEA, SLA, etc.) may rely on the stated SSIC when issuing licences. Activities requiring Employment Pass, S Pass or Work Permit considerations should be aligned with declared business activities.
• PDPA and data handling: Certain service categories imply obligations under PDPA; classification helps determine expected compliance practices.
• Updates and accuracy: If business activities change, you should update ACRA records promptly via BizFile+ to reflect the current SSIC codes and descriptions.

Step-by-step process

Follow these practical steps to identify and record the correct SSIC code.

• Review your core business activities: List the main products or services, customers and the economic function of the business.
• Consult the SSIC (latest version): The SSIC is published by the Singapore Department of Statistics. Search by keywords that describe your activities (e.g. “software development”, “food and beverage”, “consultancy”).
• Match to the most specific code: Choose the code that best describes the principal activity. Use the most specific class rather than a broad division when possible.
• Consider secondary activities: You may declare additional SSIC codes to reflect other significant business operations, especially those that generate revenue or require licences.
• Cross-check with IRAS and licence requirements: For GST, licences or sector-specific compliance, ensure the chosen SSIC aligns with regulatory expectations.
• Record the code on ACRA BizFile+: During incorporation or via an update to company particulars, enter the SSIC code and descriptive wording in BizFile+.
• Keep documentation: Retain notes explaining why you chose the code, such as product lists, contracts or brochures, in case of queries from regulators.

Common mistakes to avoid

These are frequent errors that can lead to administrative friction or incorrect compliance obligations.

• Choosing an overly broad code: Picking a generic division can obscure the company’s true economic activity and trigger incorrect benchmarking or sectoral reporting.
• Failing to update changes: Companies often change focus — for example, from trading to manufacturing — and neglect to update their SSIC, causing mismatches in GST or licence applications.
• Using inconsistent descriptions: The SSIC code and the business description on employment passes, permits or licence applications should be consistent to avoid delays from MOM or other agencies.
• Not declaring secondary activities: Omitting secondary revenue streams can affect tax assessments or grant eligibility.
• Relying on translations or local jargon: Use the SSIC wording and code numbers rather than colloquial descriptions to reduce ambiguity.

Practical examples

Examples demonstrate how to apply the SSIC selection process in common scenarios.

• Software company with SaaS and consulting: If a company primarily provides subscription-based SaaS, select the SSIC for “Software as a Service” or “Wholesale of software” where applicable, and add consulting as a secondary activity.
• F&B outlet and catering services: A restaurant’s principal activity should reflect on-site dining, while separate SSIC(s) can capture catering or food delivery operations.
• Trading company that also assembles goods: If the core activity is import and wholesale distribution, choose the wholesale trade code as primary; manufacturing or assembly should be listed if it constitutes a significant operation.

How a corporate secretary can help

A corporate secretary and corporate services provider can add value when choosing and maintaining SSIC codes:

• Conducting an initial review of business activities and recommending the most appropriate SSIC codes aligned to ACRA and IRAS expectations.
• Preparing and filing ACRA BizFile+ updates for changes to principal activities or additional SSIC codes.
• Coordinating with your accountant on GST registration via IRAS myTax Portal and aligning records for tax and accounting systems.
• Advising on licence applications and consistency across Employment Pass, S Pass or Work Permit submissions and company records.

Frequently Asked Questions

How often should I review my SSIC code?

Review your SSIC when business activities change materially, before submitting licence applications, or at least annually as part of your internal compliance review and Financial Year End planning.

Can I have more than one SSIC code?

Yes. You can record multiple SSIC codes to reflect secondary or ancillary activities. Ensure the primary code accurately reflects the principal revenue-generating activity.

Will an incorrect SSIC code trigger penalties?

An incorrect SSIC itself is unlikely to lead to a fine, but inconsistencies can delay licence approvals, GST registration, or raise queries from ACRA or IRAS. Correct the record promptly via BizFile+ to avoid complications.

Does SSIC selection affect employment pass applications?

Yes. MOM assesses applications in context of company activities. Ensure your declared business activities, SSIC code and job descriptions for Employment Passes, S Passes or Work Permits are consistent.

Key takeaways

• Select the SSIC code that best describes your principal economic activity and add secondary codes where appropriate.
• Use the official SSIC registry and prefer the most specific class available.
• Keep ACRA BizFile+ records up to date and ensure consistency with IRAS, MOM and licence applications.
• Review your SSIC periodically and document why a code was chosen to support audits or queries.
• Engage a corporate secretary or corporate services provider to assist with filings, GST considerations and cross-agency consistency.
