From 9 May 2026, ACRA automatically converted all Singapore entities’ SSIC 2020 codes to the new SSIC 2025 Singapore classification and introduced dedicated BizFile e‑services for share changes. To stay compliant, you should verify that your new SSIC 2025 code correctly reflects your business activities and use the new BizFile workflows whenever you allot or transfer shares or change paid‑up capital.
This guide explains why SSIC 2025 matters, how to check and update your code, and how to use the new BizFile share‑related e‑services instead of generic lodgements.
1. What changed: SSIC 2025 and new BizFile share e‑services
From May 2026, ACRA made two important changes for Singapore companies:
All existing SSIC 2020 business activity codes were automatically mapped to SSIC 2025 codes.
New, dedicated BizFile e‑services were introduced for updating share information, so companies no longer rely on broad, catch‑all lodgements for share changes.
For founders and directors, this means you should:
Confirm that your automatically converted SSIC 2025 code is accurate.
Use the new BizFile share allotment, transfer and paid‑up capital e‑services for future changes.
These steps help keep your ACRA records clean and reduce the risk of compliance issues or confusing data for banks, investors and regulators.
2. Why your SSIC 2025 Singapore code matters
Your SSIC 2025 code is the official description of what your company does, and it is used by banks, investors and government agencies to understand your business activity.
If the code is wrong or outdated, it can create friction when you open accounts, apply for services or explain your business to stakeholders.
2.1 What the SSIC 2025 code is
The SSIC (Singapore Standard Industrial Classification) is a structured list of business activity categories.
SSIC 2025 is the updated version that replaced SSIC 2020.
Each company has:
A primary SSIC code for its main business activity.
Optionally, secondary codes for significant additional activities.
2.2 How an inaccurate SSIC can affect your company
An incorrect or poorly chosen SSIC code can:
Misrepresent your business model to banks and investors.
Cause confusion when comparing your company to peers in the same sector.
Lead to more questions during due diligence or compliance reviews.
For example, a software‑as‑a‑service startup that is coded as a generic “trading” business may face extra questions from banks or partners trying to understand its risk profile.
2.3 Why the automatic conversion needs your review
ACRA’s automatic mapping from SSIC 2020 to SSIC 2025 is convenient, but it is based on the old code, not on your current business reality.
You should review the new code if:
Your business model has evolved since incorporation.
You pivoted into a different product, market or revenue stream.
You previously selected a “close enough” code just to complete incorporation.
A short review now can prevent mismatches between how you operate and how you are officially classified.
3. How to check your company’s SSIC 2025 code in BizFile
To check your SSIC 2025 code, log in to BizFile, access your company profile and review the listed primary and secondary business activities.
The exact screen labels in BizFile may change over time, but the general approach is consistent.
3.1 Prepare what you need
Before you start, make sure you have:
Your CorpPass or other accepted login credentials for BizFile.
Your company name or UEN (Unique Entity Number).
If you work with a corporate secretary, you can also ask them to retrieve the SSIC 2025 information for you.
3.2 Step‑by‑step: Viewing your SSIC 2025 code
Log in to BizFile.
Use your authorised credentials to access the system.
Search for your company.
Enter your company name or UEN to open your entity’s profile.
Open the business profile or entity information.
Navigate to the section that shows your company’s registered particulars.
Locate the business activity section.
Look for fields labelled along the lines of “Primary Activity”, “Secondary Activity” or “SSIC”.
Note the SSIC 2025 codes and descriptions.
Record both the numeric codes and their textual descriptions for your internal records.
Once you have the codes, compare them with your actual operations to decide if an update is needed.
4. How to decide if your SSIC 2025 code needs updating
Update your SSIC 2025 code if the current description no longer matches your main revenue‑generating activity or significantly understates a major new line of business.
You are not changing your legal objects; you are aligning the classification with what you actually do.
4.1 Questions to ask about your current code
Consider the following:
Does the primary SSIC description match your current main source of revenue?
If you have pivoted, does the code still describe your old model instead of the new one?
Are you using a very generic category when a more specific one would be clearer?
Do you have a major secondary activity (for example, consulting plus software development) that is not reflected at all?
If the answer to any of these is “no” or “not really”, an update is worth considering.
4.2 Typical situations where an update is sensible
Founders often need to refresh their SSIC when:
A side project became the main business line.
The company moved from services to products, or vice versa.
The business expanded into a new sector that now contributes a large share of revenue.
The original code was chosen quickly just to complete incorporation.
Keeping the SSIC 2025 code aligned with your real activities makes later conversations with banks, investors and regulators more straightforward.
5. How to update your SSIC code with ACRA
To update your SSIC 2025 code, you file a change of business activity through BizFile, selecting the correct primary and (if relevant) secondary codes.
The exact e‑service name may evolve, but the core steps remain similar.
5.1 Internal preparation before filing
Before logging into BizFile, take these internal steps:
Agree on the new activity description.
Directors should align on what the company’s main activity is.
Identify the correct SSIC 2025 code(s).
Use the official SSIC 2025 list or seek professional help to choose the most accurate code.
Update internal records.
Ensure your business plan, website and key documents are consistent with the new description.
5.2 Filing the change in BizFile
Once you are ready:
Log in to BizFile as an authorised filer.
Select the e‑service for changing business activity.
Look for an option related to updating business activities or SSIC codes.
Enter the new primary SSIC 2025 code.
Provide the code and confirm the description matches your intended activity.
Add or adjust secondary codes if applicable.
Include significant secondary activities that you want reflected.
Review and confirm the changes.
Double‑check that the new codes correctly describe your business.
Submit the filing and keep a copy.
Save the acknowledgement for your records and share it with your corporate secretary.
If you are unsure about the best code, many companies work with a corporate services provider to avoid misclassification.
6. New BizFile e‑services for share allotments, transfers and paid‑up capital
ACRA has introduced dedicated BizFile e‑services for share allotments, share transfers and changes in paid‑up capital, replacing the need to use generic lodgements for these updates.
For founders and directors, this means that share‑related changes should now be filed through the specific share e‑services, not bundled into broad, non‑specific forms.
6.1 Why the new share e‑services matter
Using the dedicated BizFile share e‑services helps you:
Keep ACRA’s share and capital records structured and accurate.
Reduce the chance of missing required information in a generic lodgement.
Make it easier for banks, investors and counterparties to understand your cap table.
Over time, clean and consistent share data can also simplify due diligence and corporate actions such as fundraising or exits.
6.2 Types of changes you should file via the new e‑services
The new BizFile e‑services are designed for common share and capital events, including:
Share allotments – issuing new shares to founders, employees or investors.
Share transfers – moving existing shares from one shareholder to another.
Changes in paid‑up capital – reflecting additional capital injections or other capital adjustments.
Instead of using a generic change‑of‑particulars lodgement, you select the specific e‑service that matches the transaction.
7. How to use the BizFile share allotment e‑service
To record a share allotment, you should first complete the corporate approvals and then file the details through the BizFile share allotment e‑service.
The BizFile form captures the new shares, recipients and resulting capital.
7.1 Prepare the corporate approvals
Before you file anything with ACRA, ensure that the company has properly approved the allotment.
Typical internal steps include:
Directors approving the allotment in line with the company’s constitution.
Shareholders approving the issue where required.
Preparing the necessary resolutions and share subscription documents.
The exact approvals depend on your constitution and shareholder arrangements, so many companies seek professional advice for significant allotments.
7.2 Information you will usually need for the e‑service
When using the BizFile share allotment e‑service, be ready with:
The number of new shares being issued.
The class of shares (for example, ordinary, preference) if your company has multiple classes.
The issue recipients and their identifying details.
The resulting shareholdings after the allotment.
The updated paid‑up capital amount.
Having this information prepared in a cap table or spreadsheet makes the filing smoother.
7.3 Filing the allotment in BizFile
A typical workflow looks like this:
Log in to BizFile as an authorised filer.
Select the share allotment e‑service.
Choose the option dedicated to issuing new shares.
Enter company details.
Confirm the company name and UEN.
Input allotment details.
Provide the number of shares, class, allotment date and consideration where required.
Update shareholder positions.
Reflect the new shareholdings for each shareholder.
Confirm the new paid‑up capital.
Ensure the capital figure matches your internal records.
Review, submit and save the acknowledgement.
Keep the filing confirmation with your corporate records.
Using the dedicated allotment e‑service keeps your share history clear and machine‑readable in ACRA’s system.
8. How to use the BizFile share transfer e‑service
To record a share transfer, you should complete the transfer documentation and then use the BizFile share transfer e‑service to update the shareholder register with ACRA.
This ensures that ACRA’s records match your internal register of members.
8.1 Internal steps before filing a transfer
Before you file the transfer with ACRA, you should:
Prepare and execute the share transfer form between transferor and transferee.
Obtain any board or shareholder approvals required under your constitution or shareholders’ agreement.
Update your internal register of members to reflect the new ownership.
Only after these steps are completed should you proceed to update ACRA.
8.2 Information typically required for the transfer e‑service
For the BizFile share transfer e‑service, you will usually need:
Details of the transferor (current shareholder).
Details of the transferee (new shareholder).
The number and class of shares being transferred.
The effective date of the transfer.
The resulting shareholdings of both parties.
Having a clean cap table makes it much easier to complete the form accurately.
8.3 Filing the transfer in BizFile
The general steps are:
Log in to BizFile.
Select the share transfer e‑service.
Choose the option specifically for transferring existing shares.
Identify the company.
Confirm the company name and UEN.
Enter transfer details.
Input the transferor, transferee, number of shares and date of transfer.
Update the shareholder list.
Reflect the new ownership structure after the transfer.
Review and submit.
Check that the updated cap table matches your internal records.
Save the acknowledgement.
File it together with the transfer documents and resolutions.
Using the dedicated transfer e‑service helps avoid ambiguity that can arise when share changes are reported only in generic forms.
9. How to change paid‑up capital in BizFile
To change your paid‑up capital, you should first complete the capital transaction internally and then update ACRA using the BizFile e‑service dedicated to changes in paid‑up capital.
This keeps your legal capital position aligned with your financial reality.
9.1 Common reasons to change paid‑up capital
Singapore companies adjust paid‑up capital for several reasons, such as:
New cash injections from founders or investors.
Capitalising shareholder loans into equity.
Other corporate restructuring exercises.
Whatever the reason, the change should be properly documented and reflected in both your accounting records and ACRA filings.
9.2 Internal corporate steps
Before filing with ACRA, you should:
Obtain the necessary board and shareholder approvals for the capital change.
Ensure the funds or consideration have been properly received or accounted for.
Update your cap table and accounting records to reflect the new capital.
9.3 Filing the paid‑up capital change in BizFile
When using the BizFile e‑service for paid‑up capital changes:
Log in to BizFile.
Select the paid‑up capital change e‑service.
Choose the option that specifically relates to updating capital.
Confirm company details.
Verify your company name and UEN.
Enter the new paid‑up capital figure.
Provide the updated amount and relevant details requested.
Check consistency with share data.
Ensure the capital figure aligns with the number and type of shares on record.
Submit and retain the acknowledgement.
Keep the confirmation with your corporate and financial records.
Using the dedicated capital e‑service helps keep your capital history clear for future investors and auditors.
10. Keeping shareholder details and ACRA records aligned
To maintain ACRA compliance, your internal shareholder register, cap table and BizFile records should always tell the same story.
Whenever you allot or transfer shares or change paid‑up capital, you should:
Update your internal registers and cap table.
Use the specific BizFile share or capital e‑service that matches the transaction.
Keep resolutions, agreements and acknowledgements together in your corporate records.
This discipline reduces the risk of:
Disputes over ownership.
Delays in fundraising or exits due to unclear records.
Questions from banks, regulators or counterparties about inconsistent information.
Many founders delegate this work to a corporate secretary, but directors remain responsible for ensuring that filings are accurate and timely.

12. FAQs: SSIC 2025 codes and BizFile share updates
How do I know if ACRA has already converted my company to SSIC 2025?
ACRA has automatically converted all registered entities’ SSIC 2020 codes to SSIC 2025 from 9 May 2026, so your company should already have an SSIC 2025 code. You can confirm this by logging into BizFile, opening your company profile and checking the business activity section for the current SSIC code and description.
Do I have to change my SSIC 2025 code if my business has not changed?
You do not need to change your SSIC 2025 code if the automatically converted code still accurately reflects your main business activity. You should only file an update if the current description is clearly misaligned with what your company actually does.
Can I have more than one SSIC 2025 code for my company?
You can have one primary SSIC 2025 code and, where relevant, additional secondary codes to reflect significant secondary activities. The primary code should always represent your main revenue‑generating business line.
What happens if I keep using generic BizFile lodgements for share changes?
If you rely on generic lodgements instead of the dedicated share e‑services, your share and capital information in ACRA may become less structured and harder to interpret. Using the new share allotment, transfer and paid‑up capital e‑services helps ensure that your ownership records are clear, consistent and easier for stakeholders to understand.
Do I need professional help to update my SSIC or file share changes?
You can file SSIC updates and share changes yourself if you are comfortable with BizFile and corporate documentation. However, many founders work with a corporate secretary or service provider to reduce errors, especially for more complex transactions or fundraising rounds.
Does changing my SSIC 2025 code affect my taxes or licences automatically?
Changing your SSIC 2025 code updates how your business is classified with ACRA, but it does not automatically change your tax position or licences. If your underlying business activities have changed, you should separately consider any tax, licensing or regulatory implications and seek professional advice where needed.
13. Need help keeping your SSIC and share records clean?
Keeping your SSIC 2025 classification aligned with your real business and using the right BizFile e‑services for share allotments, transfers and paid‑up capital changes will save you time and questions later from banks, investors and regulators.
If you prefer to focus on building your company instead of managing filings, IncSG can help you understand what needs to be updated, prepare the supporting documents and work with your chosen corporate services provider so your ACRA records stay accurate and investor‑ready.
