What Is a Registered Office Address in Singapore?

Every company incorporated in Singapore must have a registered office address. This is a legal requirement under the Companies Act 1967 and is not optional — it is the official address on record with the Accounting and Corporate Regulatory Authority (ACRA) where statutory notices, government correspondence, and legal documents are sent.

The registered office address is publicly available on ACRA’s Bizfile portal. Any member of the public, creditor, or regulatory authority can look it up. For this reason, many company directors and shareholders choose not to use their home or personal address as the registered office — and opt instead for a professional registered office service.

At Singapore Secretary Services, we provide registered office address services as part of our corporate secretarial packages. In this guide, we explain everything you need to know: the legal requirements, what types of addresses are acceptable, what must happen at the address, and how to change it when needed.

Legal Requirements Under the Companies Act

The key provisions governing registered office addresses are found in the Companies Act (Cap. 50), specifically:

  • Section 142 — Every company must have a registered office in Singapore to which all communications and notices may be addressed. The registered office must be open and accessible to the public during ordinary business hours.
  • Section 143 — The company must lodge its registered office address with ACRA. Any change must be notified to ACRA within 14 days of the change taking effect.

These requirements apply to:

  • Private limited companies (Pte. Ltd.)
  • Public companies (Ltd.)
  • Branch offices of foreign companies
  • Sole proprietorships and partnerships registered under the Business Names Registration Act are subject to similar requirements under their respective legislation.

What Qualifies as a Registered Office Address?

Not all addresses qualify as a registered office. ACRA has specific requirements:

1. Must Be a Physical Address in Singapore

The address must be a physical location in Singapore. P.O. Boxes are not acceptable as a registered office address. The address must include a valid postal code, street name, and unit number where applicable.

2. Must Be Accessible During Business Hours

The registered office must be open and accessible to the public during ordinary business hours (generally 9 am to 5 pm on weekdays, excluding public holidays). This does not mean a member of the public can simply walk in and demand to inspect company records — but it does mean someone must be able to receive documents and correspondence on behalf of the company during those hours.

3. Residential Addresses: Home Office Scheme

Singapore residents may use their HDB flat or private residential property as a registered office address under the Home Office Scheme, subject to conditions set by the Housing Development Board (HDB) or the Urban Redevelopment Authority (URA).

However, there are practical concerns with using a residential address:

  • Your home address becomes publicly searchable on ACRA Bizfile
  • Creditors, process servers, and third parties can find and attend at your home
  • It may not project the right professional image to clients and business partners
  • Certain types of businesses are not permitted to operate from a residential address

For most companies, a professional registered office address provided by a corporate secretarial firm is more practical and appropriate.

4. Commercial Address

Any commercial address in Singapore — an office, a co-working space, or a business address provided by a registered filing agent — is generally acceptable as a registered office. The provider must be willing to receive and forward official correspondence to the company.

What Must Happen at the Registered Office

Under the Companies Act, certain statutory records must be kept at the registered office or at another location in Singapore (with ACRA notified of the alternative location). These include:

  • Register of Members (Section 190, Companies Act) — the list of all shareholders
  • Register of Directors, Chief Executive Officers, and Secretaries (Section 173)
  • Register of Registrable Controllers (RORC) — required under the Accounting and Corporate Regulatory Authority Act
  • Copies of all instruments creating charges (if applicable)
  • Minutes of general meetings
  • Audited financial statements (for companies that are not exempt from audit)

In practice, most of these records are maintained by your corporate secretary, who will keep them at the registered office or in a secure digital system. ACRA has moved toward a digitalised statutory register system, and many requirements can now be fulfilled through ACRA’s electronic registry.

Using a Corporate Secretarial Firm’s Address

The most common approach for Singapore companies — especially startups, SMEs, and foreign-owned companies — is to use the address of their registered filing agent (i.e., their corporate secretarial firm) as the registered office address.

This arrangement offers several advantages:

  • Privacy — Directors and shareholders do not expose their personal or operational addresses publicly
  • Professionalism — A professional business address (often in the CBD or a reputable commercial building) lends credibility
  • Convenience — ACRA notices, IRAS correspondence, and other government mail are received and forwarded promptly
  • Compliance — A reputable corporate secretarial firm will ensure the office is open during business hours and the address remains valid
  • Bundle with other services — Most firms offer the registered office address as part of a broader corporate secretarial package, covering annual returns, board resolutions, and statutory compliance

At Singapore Secretary Services, our registered office address service is included in our corporate secretarial packages. We maintain all your statutory records, receive and forward official correspondence, and ensure your company remains compliant with all ACRA requirements.

What Must Be Displayed at the Registered Office

Under the Companies Act, every company must display its registered name and Unique Entity Number (UEN) at its registered office. Specifically:

  • The company’s registered name must be conspicuously displayed outside every office or place of business where the business is carried on
  • The company’s UEN (issued by ACRA upon incorporation) must appear on all official communications, including letters, invoices, bills, receipts, and notices

Where a corporate secretarial firm’s address is used, this is typically handled through a nameplate or letterbox listing at the firm’s premises, or through digital compliance (e.g., having the registered name and UEN on the firm’s internal mail system for the company).

How to Change Your Registered Office Address

Companies frequently need to change their registered office address — when they move to a new office, switch corporate secretarial providers, or restructure their operations. The process is straightforward:

Step 1: Board Resolution

The directors must pass a board resolution approving the change of registered office address. This resolution should record the old address, the new address, and the effective date of the change. Your corporate secretary will typically prepare this resolution for signing.

Step 2: Lodge a Notice of Change with ACRA

The company must file a Notice of Change of Registered Office Address with ACRA via Bizfile+. This must be done within 14 days of the change taking effect. The filing is done by a registered filing agent (your corporate secretary) or by a director who has a Corppass account.

The information to be lodged includes:

  • New registered office address (full address with postal code)
  • Date the change takes effect
  • Confirmation that the address meets statutory requirements

Step 3: Update Business Records and Stationery

After ACRA confirms the change, you should update your company’s business records, letterheads, invoices, website, and any other materials that display the registered office address. Note that the UEN remains the same — only the address changes.

Step 4: Inform Relevant Parties

You should also notify key stakeholders of the address change, including:

  • Your bank(s)
  • The Inland Revenue Authority of Singapore (IRAS) — update your address on myTax Portal
  • Central Provident Fund Board (CPF) — if you have employees
  • Suppliers and customers
  • Insurers

Consequences of Non-Compliance

Failure to comply with the registered office requirements under the Companies Act can result in:

  • Fines — The company and every officer in default may be fined for failing to maintain a registered office, failing to display the company name, or failing to notify ACRA of a change within 14 days
  • Struck off — ACRA may strike off a company from the register if it fails to maintain a registered office or if correspondence is returned undelivered
  • Missed legal notices — If the registered office is not operational or mail is not received, the company may miss critical court documents, regulatory notices, or tax assessments — with potentially serious legal and financial consequences

The 14-day deadline for notifying ACRA of address changes is strictly enforced. Courts have held that service of legal documents at a company’s registered office is deemed valid service even if the company has moved but failed to update ACRA — meaning the company cannot later claim it did not receive the document.

Registered Office vs. Principal Place of Business

These two concepts are often confused but are distinct:

Registered Office Principal Place of Business
Official address for statutory purposes and legal correspondence Where the business actually operates
Must be registered with ACRA Not required to be the same as registered office
Can be a corporate secretary’s address Typically where staff work and business activities occur
Must be open during business hours May have different operating hours
Publicly searchable on ACRA Bizfile May or may not be publicly listed

Many companies maintain a professional registered office (at their corporate secretary’s premises) while operating out of a separate office, co-working space, or even remotely. Both addresses serve different purposes and both must be kept current.

Practical Tips for Managing Your Registered Office

  • Use a reputable corporate secretarial provider — The registered office address should be at a firm that will reliably receive and forward official correspondence. Missed ACRA or IRAS notices can have serious consequences.
  • Act within 14 days when you change address — Don’t delay the ACRA filing. Calendar the task and assign it to your corporate secretary the moment a move is confirmed.
  • Keep your ACRA records accurate — ACRA’s public records are used by banks, investors, and counterparties. An out-of-date address erodes trust and can delay transactions.
  • Don’t use a residential address if you value privacy — Once a residential address appears on Bizfile, it is publicly accessible and cannot easily be removed from historical records.
  • Bundle the service — The registered office is almost always offered as part of a broader corporate secretarial package. Bundling saves cost and ensures seamless compliance across all statutory obligations.
