CHANGE SSIC CODE / SINGAPORE BUSINESS ACTIVITIES / BIZFILE UPDATE
Change a Singapore Company's SSIC Code: Updating Business Activities
Record what changed, file the accurate particulars and resolve the operating consequences.
A Singapore local company updates its primary and secondary SSIC activities through Bizfile’s entity-information route. ACRA generally requires notification within 14 days of the change; additional activities have a separate General Lodgement route in its current guidance.
Define the actual change and effective date before filing. The main risk is treating an accepted classification update as permission to begin a newly regulated activity, or entering an inaccurate date to hide a late notification.
Key takeaways
- Identify a classification error separately from a genuine change of operations.
- Use current official activity descriptions and a supported effective date.
- The local-company notification rule is generally 14 days, not the foreign-company 30-day rule.
- ACRA lists the entity-information update as free; professional and other approval costs are separate.
- Reconcile licences and affected business records before closing the change.
Define the business change and its effective date
Prepare a before-and-after record of what the company actually does. A new marketing description may still describe the same activity; adding manufacturing to a trading operation or operating a new service can be a substantive change. Identify whether the problem is a wrongly selected code, a genuine change in business activity or both. The explanation and supporting records should reflect that distinction.
The effective date should describe the real change, not the day somebody finally opens Bizfile. Retain contracts, operational decisions, service descriptions or other evidence that explains the date. Do not choose a false recent date merely because an earlier change was not reported on time. Where an old filing error or disputed date is involved, ask ACRA or the CSP about the appropriate correction route.
The underlying Singapore company registration framework establishes the entity and its initial particulars. Updating the activity is a later maintenance task for that company; it does not require pretending to incorporate a new business whenever the commercial offering changes. Confirm the UEN before any update.
What changed in the operation?
Clarify the activity, effective date and company record before choosing the filing.
Choose the code from the activity, not the desired outcome
ACRA’s SSIC guidance describes the five-digit classification for primary and applicable secondary activities. Search the current official descriptions and compare them with the substance of the operation. Avoid selecting a broad-sounding code to conceal a regulated feature or to manufacture a grant, bank or work-pass eligibility claim.
Use the activity-to-code selection checks to distinguish, for example, providing advice from buying and reselling goods, or distributing a product from manufacturing it. If two activities exist, document why one is primary and what supports the secondary description. A website category is useful context but does not replace the actual contracts and revenue model.
| Question | Evidence to compare | Avoid |
|---|---|---|
| What is delivered? | Contracted goods, services and operating steps | Choosing a classification from the business name alone. |
| Which activity is primary? | Actual economic substance and relevant operating information | Automatically retaining the old primary code after the business has changed. |
| Is there a secondary activity? | A separate real line of business | Adding a code for a purely speculative service. |
| Are more activities involved? | Complete activity map | Assuming the two visible fields describe every permitted operation. |
ACRA’s current update guidance says additional business activities beyond the primary and secondary fields use General Lodgement (Others), with the relevant SSIC codes. Confirm that route for the actual situation rather than omitting real activities because the main screen has two fields.
Submit the authorised Bizfile activity update
The ACRA entity-information update guide dated 20 October 2026 identifies authorised officers, CSPs and Group of Companies as filing routes. For a local company, changes must generally be notified within 14 days; its separate foreign-company rule is 30 days. This article concerns a Singapore local company and does not apply the longer branch deadline to it.
Open the correct entity’s information in Bizfile, select Business activities and Edit, search for or enter the SSIC code and select the matching description. Enter the effective date, add the applicable secondary activity, then review and confirm the accurate information and declaration. Preserve the confirmation and notification in the Bizfile inbox. These steps follow the published guide; no private account was accessed for this article.
ACRA lists updating entity information as free with immediate processing. That published transaction characteristic, checked on 29 October 2026, does not mean a sector licence or bank review is also immediate. A CSP may charge separately for its professional work; confirm the scope and GST treatment in the engagement. Do not describe an agency’s free transaction as an all-inclusive compliance service.
Does the update affect other permissions?
Check the licence and business-record dependencies alongside the Bizfile transaction.
Reconcile affected permissions and third-party records
An SSIC update is not an operating licence. Compare the new activities with existing sector permissions, approved premises use and any product or personnel requirements. Determine which items are unaffected, need notification or need a new approval from the relevant authority. Keep the agency’s answer with the change record, especially where the proposed launch depends on it.
| Record or permission | Follow-up question | Completion evidence |
|---|---|---|
| Licence and premises | Does the authorised activity and site cover the revised operation? | Applicable amendment, new approval or supported non-applicability review. |
| Bank and payment provider | Does the business profile still describe actual transactions? | Updated profile or response where the provider requires it. |
| Contracts and insurance | Do services, risk cover and representations remain accurate? | Reviewed terms and endorsements where needed. |
| Tax and accounting | Does the change affect the tax treatment, reporting or accounts setup? | Documented assessment and updated processes as applicable. |
Do not assume every downstream item must change; assess the facts and the receiving party’s conditions. Equally, do not assume other agencies automatically accept the new business model because ACRA’s information is updated. This reconciliation is an internal control method, not a claim that every listed follow-up is a statutory filing.
Resolve a rejected or incorrect update without duplicating the problem
If the wrong entity appears, stop before submission and correct the access or entity selection. If a code cannot be found, search current official descriptions and verify the activity; do not select a near-sounding result just to finish. Where the problem is eligibility or authority, the legitimate officer or filing provider should resolve it rather than share a personal login.
After submission, compare the resulting activity record with the approved instruction. If the effective date or description is wrong, preserve the acknowledgement and seek the proper correction advice. Keep a trail of the old value, submitted value and intended correct value. An internal spreadsheet changed to match the mistake does not correct the official record.
For an overdue notification, deal with the actual date and any agency requirements candidly. The relevant filing or correction response can depend on the facts. This article does not invent a universal penalty, waiver or recovery deadline. Assign the issue to a named person and monitor it until the agency position and business records are reconciled.
Close the activity change with a reconciled evidence pack
The update is complete when the ACRA record is accurate and the dependent operating questions are resolved. Keep the rationale, effective date, selected descriptions, filing confirmation and follow-up decisions together. Inform the responsible operational, accounting and compliance staff of any conditions before the revised activity starts.
If the business description remains uncertain or the new activity exceeds an existing permission, obtain a specific classification or regulatory assessment. Do not release a regulated service merely because the company profile now displays a matching SSIC code.
Close the change with clear evidence
Coordinate the accurate company particulars and the operational decisions that remain.
