Registered Office Address in Singapore: What the Law Requires, and What Does Not Qualify

Registered Office Address in Singapore: What the Law Requires, and What Does Not Qualify

Last updated: 18 September 2026 · Author: SBC Team

Section 142 of the Companies Act 1967 requires every Singapore company to have a registered office within Singapore from the date of its incorporation, and that office must be open and accessible to the public for not less than three hours during ordinary business hours on each business day. It is the address to which all communications and notices may be addressed. Default is an offence carrying a fine of up to S$5,000 and a further default penalty.

This guide covers how the registered office differs from your business and mailing addresses, what will not qualify, when a home address works, which registers must be kept there, how to change the address with the Accounting and Corporate Regulatory Authority (ACRA), and what happens when an address stops being answered.

What the Companies Act Requires

The rule has three parts, and they are worth separating because most guides collapse them into one.

• Location. The office must be within Singapore, and it exists from the date of incorporation, not from the date you start trading.
• Accessibility. It must be open and accessible to the public for at least three hours during ordinary business hours on each business day.
• Function. It is the address to which all communications and notices may be addressed, which is why ACRA, the Inland Revenue Authority of Singapore (IRAS), the Ministry of Manpower and the courts all use it.

Section 143 adds a filing obligation founders rarely hear about. You lodge notice of the situation of the registered office and of the days and hours it is open, and any later change within 14 days. No notice of hours is needed if the office is open at least five hours during ordinary business hours on each business day, which most serviced and corporate-secretarial addresses clear comfortably.

A Change Is Coming, but It Has Not Started Yet

The Corporate and Accounting Laws (Amendment) Act 2025 will remove the fixed minimum opening-hours requirement once the relevant provisions commence, and replace it with a notice-based regime: anyone entitled to inspect company records gives reasonable notice, and the company then makes them available for at least two hours on each relevant business day. The Act is commencing in tranches, and the first tranche took effect on 6 May 2026. The registered-office change was not part of it: as at 18 September 2026, section 142 on Singapore Statutes Online still requires the office to be open and accessible to the public for not less than 3 hours during ordinary business hours on each business day. That is the standard your address is held to today. Check ACRA’s announcements before relying on the new position.

Registered Office, Business Address and Mailing Address Are Three Different Things

These get used interchangeably in marketing copy and on bank forms. Only one of the three is a statutory concept.

They can all be the same address, and for companies with a physical office they usually are. The distinction bites when a founder assumes the address on the invoice is the address ACRA will write to.

What Does Not Qualify

An Overseas Address

Section 142 says “within Singapore” and there is no exception. A foreign parent’s head office, a director’s home in Shanghai, and a regional office in Kuala Lumpur all fall outside it. Ownership can sit anywhere; the registered office cannot.

A P.O. Box

A P.O. Box cannot be open and accessible to the public, and it is not a place a person can attend. ACRA does not accept one, and the same reasoning rules out a mailbox suite with no premises behind it.

An Address You Cannot Rely On

You need the owner’s or tenant’s consent, so a friend’s office, a lapsed co-working plan, or a provider’s address after the contract ends can all be withdrawn without warning. A real Singapore address that is locked during business hours fails the accessibility limb too. It looks correct on the business profile, so the problem surfaces only when someone attends or a notice goes unanswered.

Using a Home Address: The Home Office Scheme

You can run a small business from home and use that address as your registered office, but you register under the Home Office Scheme first. The Housing & Development Board administers it for HDB flats and the Urban Redevelopment Authority for private residential property. The administration fee is S$20, non-refundable and inclusive of GST. URA has granted a one-time permit since 6 December 2010, with no five-yearly renewal, and either agency can revoke on breach.

The conditions are strict, and they are why the scheme suits fewer businesses than expected:

• Activity at the premises must be administrative in nature. Everything else happens elsewhere.
• No clients or customers visit the home, and no signage, advertisements or posters go on the flat, its door or its windows.
• Up to two non-residents may be engaged in the business at the premises. HDB counts employees, partners and directors towards that limit.
• No selling of physical goods at or around the premises, and no loading, unloading or storage of goods.
• The property stays a home, with no noise, smoke, odour or heavy traffic for the neighbours.

Home Office approval permits the use of the residence; you still lodge the address with ACRA in the normal way. One consequence founders weigh late is that the home address becomes a public record any bank, supplier or litigant can read.

What a Virtual or Serviced Office Has to Deliver

A virtual office address can satisfy section 142, and for many early-stage companies it is the sensible answer. Whether a particular one does depends on what happens behind the door, not on what the package is called. Mail forwarding alone is not enough. The arrangement has to deliver four things:

• Real premises in Singapore that a person can attend during the stated hours, not a box number.
• Attendance during the hours the company has declared, so anyone arriving in person is met.
• Receipt of statutory mail from ACRA, IRAS and the courts, logged and escalated to a named person at your company.
• A response time agreed in writing. A notice carrying a 30-day clock is worth much less on day 26.

The risk with a provider who is unreachable during the required hours is not really the fine. It is that the company keeps receiving notices it never sees. Our guide to virtual offices and ACRA compliance covers the provider side in detail.

The Registers That Must Be Kept, and Where

The registered office is not only a letterbox. Several statutory records are tied to it.

• Register of registrable controllers. Kept at the company’s registered office or at that of a registered filing agent appointed to keep it, and not open to the public. Controller information is also lodged with ACRA’s central register; the register you keep does not replace that filing.
• Register of nominee directors. The same two prescribed places, and the same confidentiality.
• Minute books. Under section 189, minutes of general meetings are kept at the registered office or the principal place of business in Singapore, and any member may inspect them without charge.
• Register of members. For a private company, ACRA has kept the electronic register since 3 January 2016 under section 196A, and that register is the operative record. The registers of directors, chief executive officers, secretaries and auditors sit with the Registrar under section 173.

If any register sits elsewhere, the address where the registers are kept is itself a filed particular that must be updated when it changes. Holding them with whoever provides your company secretarial services is the usual arrangement, since that is the party maintaining them.

How to Change Your Registered Office Address

1. Pass a directors’ resolution approving the new address. A company with a single director can sign a written resolution.
2. Log in to Bizfile, ACRA’s filing portal, open the Entity Information page, select Office address, enter the new postal code and the effective date of change, then review and submit.
3. Update your office hours in the same place if they changed, and the registers address if the registers moved with you.
4. Tell everyone else. Banks, insurers, IRAS, work-pass records, landlords and licensing authorities do not learn about it from ACRA.

ACRA charges no fee and processing is immediate, so the public record carries the new address as soon as the lodgement goes through. Until it does, the old address remains the address of record.

The deadline is 14 days from the date of change for a locally incorporated company. A registered foreign company has 30 days. Late lodgement attracts a composition sum that scales with the delay.

What Happens When the Address Goes Dead

Under section 387, a document may be served on a company by leaving it at, or sending it by registered post to, the registered office. Service is complete when that happens. Nobody has to read it, sign for it, or still be renting the unit. A statutory demand, a writ or an ACRA notice delivered to an address you abandoned is served, and the clock on your response starts running.

Once notices stop being answered, the company reads as uncontactable. Section 344 lets the Registrar strike a company off where there is reasonable cause to believe it is not carrying on business or is not in operation. The Registrar writes to the company and to its directors, secretaries and members. If no answer showing cause to the contrary arrives within 30 days, a notice may be published in the Gazette, and 60 days later the name may be struck off and the company dissolved.

Every step of that sequence is addressed to the registered office. A director who moved on, changed email, or assumed the corporate secretary was handling it can find the company dissolved without reading a single notice. Restoration is possible, but it is a court application and costs far more than maintaining the address would have.

Choosing a Provider: A Short Checklist

Ask these before you sign, and ask for the answers in writing:

• Which hours is the address attended each business day, as actual times rather than “business hours”?
• Who receives statutory mail from ACRA, IRAS and the courts, and how fast does it reach a named person at my company?
• Is registered-office use permitted by the building’s by-laws and the head lease?
• Will you keep the registers of registrable controllers and nominee directors, and where will they sit?
• What happens to the address if I miss a payment, and how much notice do I get before it is withdrawn?
• Who lodges the change if I move, and who removes the address when the engagement ends?

A provider who answers the first two slowly will answer a court document slowly.

Frequently Asked Questions

What is a registered office address in Singapore?
It is the address a company must maintain within Singapore from the date of incorporation under section 142 of the Companies Act 1967. All notices may be addressed to it, it appears on the company’s public ACRA business profile, and legal documents served there are validly served on the company.

Can I use my home address as my registered office address?
Yes, if you register under the Home Office Scheme first, with HDB for an HDB flat or URA for private residential property. The administration fee is S$20. The scheme allows administrative activity only, no client visits, no signage, and up to two non-residents engaged in the business at the premises.

Can a registered office address be overseas?
No. Section 142 requires the registered office to be within Singapore, with no exception for foreign-owned companies. Shareholders and directors can be based anywhere and the company can trade anywhere, but the registered office stays in Singapore while the company is on the register.

How long do I have to tell ACRA I have moved?
Fourteen days from the date of the change for a Singapore-incorporated company, and 30 days for a registered foreign company. You file it through Bizfile on the Entity Information page. There is no filing fee and processing is immediate. Late lodgement attracts a composition sum that increases with the delay.

Is a P.O. Box acceptable as a registered office?
No. The registered office has to be open and accessible to the public during stated hours, which a P.O. Box cannot be. The same applies to a mailbox suite with no premises behind it, and to a real address nobody attends.

What happens if nobody answers mail at my registered office?
Documents left there are still validly served under section 387, so response deadlines run whether or not you see them. The company can then be treated as uncontactable, and under section 344 the Registrar may write to the company and its officers, publish a Gazette notice, and strike it off 60 days later if no cause is shown.
