Changing a Singapore company’s name is a common request. Founders rebrand, groups reorganise, and mergers force alignment of trading names. The process itself is simple — ACRA can approve and effect the change in less than a working day — but the ripple effects can catch directors off guard: bank accounts, contracts, licences, tax registrations, GST invoices and stationery all need coordinated updating. This 2026 guide walks through the ACRA name-change process, the corporate-secretarial paperwork required under the Companies Act 1967, and the downstream housekeeping that must follow.
Statutory Basis
Section 27 and Section 28 of the Companies Act 1967 govern company names in Singapore. A company may change its name only by special resolution of the shareholders passed in accordance with Section 184 of the Act, followed by lodgement of the change with the Accounting and Corporate Regulatory Authority (ACRA). The change takes effect on the date the Certificate of Incorporation on Change of Name is issued by the Registrar.
Full statutory text is available on Singapore Statutes Online.
Step 1: Choose the New Name
Every proposed name must satisfy three requirements:
- Not identical to an existing company or business name on ACRA’s register.
- Not identical or “too similar” to a registered trademark on the IPOS register — otherwise it may attract objection under Section 27 and be liable to be directed by the Registrar to change again.
- Not undesirable, offensive or deemed to imply government sponsorship without approval. Words like “bank”, “temasek”, “MAS”, “chartered”, “medical” or “university” require prior approval from the relevant regulator.
ACRA’s name-availability check is free and instant on the BizFile+ portal. A shortlisted name should also be run against the trademark register to avoid a downstream infringement claim.
Step 2: Reserve the Name
Reservation of the new name is done via BizFile+. The fee is S$15 and reserves the name for 120 days. Reservation is not strictly required — a company can apply for the name change directly — but it is prudent because it locks the name out of the pool while the shareholder resolution is being organised.
Step 3: Pass the Special Resolution
Under Section 184 of the Companies Act, a special resolution requires the affirmative vote of at least three-quarters of members entitled to vote and voting. For a private company, this is typically done via a Members’ Resolution in Writing signed by all members holding at least the requisite majority. Public and listed companies must convene a general meeting.
The resolution should:
- State the current name and the proposed new name.
- Authorise any director or the company secretary to lodge the change with ACRA.
- Direct the appropriate signatory to sign a new common seal register entry if the company has adopted a common seal.
For the mechanics of drafting Members’ Resolutions in Writing, see our Board Resolutions guide.
Step 4: Lodge the Change with ACRA
Within 14 days of the special resolution, the company must file the “Change of Company Name” transaction on BizFile+. The filing fee is S$15. Documents to be uploaded include:
- The special resolution.
- The name-approval reference (if the name was pre-reserved).
- The company’s UEN and current corporate details.
ACRA typically issues the Certificate of Incorporation on Change of Name (Form CX) on the same working day. The new UEN remains unchanged — the UEN is tied to the legal entity, not the trading name.
Step 5: Update Statutory Registers
The company secretary must update:
- The Register of Members and Register of Directors to reflect the new name in the header.
- The company’s minute book to record the resolution.
- The Register of Registrable Controllers (ROC), if maintained.
The company’s constitution does not need amendment simply because the name has changed — the constitution refers to the company by its identity, not its name.
Step 6: Notify External Parties
The most common failures around a name change happen after ACRA has issued the certificate. The following external parties must be notified:
- Banks: The bank will need the Certificate of Incorporation on Change of Name, the special resolution, and updated signatory records. Some banks close the old account and open a new one under the new name; others simply amend the account title. See our Singapore corporate bank account guide for what banks typically ask for.
- IRAS: The tax registration is updated automatically once ACRA notifies IRAS, but the GST registration certificate may need to be reissued if the company is GST-registered.
- MOM and CPF Board: Employer records are updated based on the UEN, but payroll systems and CPF submissions should be checked to make sure the new name is being used.
- Regulatory licensors: MAS, MOH, MUIS, BCA and other regulators need to be notified within the timelines set by their licences. Some licences require prior approval before the name change is effected — check the licence conditions carefully before passing the resolution.
- Customers and suppliers: Contracts continue in force under the new name (the entity is the same), but a formal notification and, where relevant, a novation letter or side letter is best practice.
- Landlord: For a leased office, notify the landlord and check whether the lease requires a formal amendment.
Step 7: Update Company Stationery and Public Statements
Section 144 of the Companies Act requires that the company’s name and UEN be shown on all business letters, statements of account, invoices, official notices, publications, bills of exchange, promissory notes, endorsements, cheques, orders, receipts and letters of credit. After the name change, all of these need to be updated. Continuing to issue invoices under the old name after the change date is a common technical breach.
Step 8: Update the Registered Office Signage
Section 143 requires the company’s name and UEN to be displayed at the registered office and every place of business. A new sign should be prepared and installed on or before the effective date of the change.
Fees, Timeline and Costs
The out-of-pocket ACRA fees are small:
- Name reservation: S$15
- Change of company name: S$15
The real cost is in the downstream updates. Budget for stationery, business cards, marketing collateral, website and email domain updates, contract and letterhead amendments, and any bank charges for cheque book reissue. Most SMEs allow a three-week window between passing the resolution and the target public launch of the new name.
When ACRA Can Direct a Name Change
Section 27(2) of the Act gives the Registrar power to direct a company to change its name where the name is identical to another, undesirable, or infringes another’s rights. A directed change must be effected within six weeks. Refusal exposes the company and its directors to daily fines under Section 27(3). Where the direction is disputed, the company can lodge an appeal with the Minister for Finance.
Interaction with Trade Marks and Branding
A registered company name does not create trade mark rights. Distinct trade mark protection must be secured separately under the Trade Marks Act 1998, via an application to IPOS. See our Singapore Trademark Registration guide. Founders often assume that ACRA name approval also protects the brand. It does not.
Corporate-Secretarial Checklist
A clean name-change file will include:
- Name-availability search result
- Name reservation acknowledgement
- Special resolution or MRIW
- Certificate of Incorporation on Change of Name (Form CX)
- Updated statutory registers
- Copies of notifications sent to banks, regulators, tax authority, landlord
- Copies of new stationery templates
- New office signage photographs
This file protects the directors when the company’s next annual review or transaction diligence checks the corporate housekeeping.
Bottom Line
The ACRA side of a name change is a 24-hour job. The company-secretarial and operational side is a two- to three-week programme. Treat it as a mini-project, run a full checklist, and the transition will be invisible to customers, banks and regulators. Skip the housekeeping and the old name will surface for years in invoices, contracts and CPF reports — always at the worst possible time.
