Singapore registered address and BizFile+ filings: Frequently asked questions

Every Singapore company must maintain a local registered office address that is open and accessible during business hours, and virtually all filings, including notifying ACRA of any change, are made through the BizFile+ portal. This guide answers the questions foreign founders ask most about Singapore registered address and BizFile+ filings.

What is the Singapore registered address requirement?

Under Singapore company law, the Companies Act 1967 requires every company to have a registered office in Singapore to which all communications and notices may be addressed, and at which the register of members and other statutory registers are kept or made available. This address appears on your BizFile+ business profile and on all official correspondence, and it must be a physical Singapore address, not merely a mailing box.

For a foreign founder incorporating without a Singapore office, this requirement often comes as a surprise: you cannot leave the field blank, and you cannot use an address in your home jurisdiction. The registered office is what ACRA, the Inland Revenue Authority of Singapore (IRAS), banks, and other government agencies will use to reach the company, so getting the Singapore registered address and BizFile+ filings right at the outset avoids compliance headaches later.

It helps to understand why this rule exists. Singapore’s company law framework is built on the idea that every legal entity operating here must be reachable and accountable, so that regulators, creditors, and members of the public can rely on a genuine point of contact. The registered office is therefore not a mere formality; it is the legal nerve centre of the company for correspondence purposes. Statutory demands, tax assessments, court documents, and even winding-up notices can be validly served at this address, so directors should never treat the field as an afterthought when completing their BizFile+ transaction. A company that fails to maintain a proper registered address risks missing critical deadlines simply because it never received the relevant notice, which is rarely accepted as an excuse by ACRA or the courts.

It is also worth distinguishing the registered office from a company’s principal place of business or trading address. Many companies, particularly those run by foreign founders with distributed teams, trade from one location, hold client meetings in another, and yet declare a completely separate registered office address for statutory purposes. This is entirely permissible under Singapore law, provided the registered office itself satisfies the accessibility and physical-presence requirements described below. The key is not to confuse “where we do business” with “where ACRA and IRAS can find us in writing”.

Who actually needs a registered address service

Foreign founders who have not yet leased office space, and who do not have a director or shareholder physically resident in Singapore with suitable premises, will typically need a commercial registered address service. This is one of the most common gaps we see among founders incorporating remotely: the incorporation filing is otherwise ready, but there is no compliant Singapore address to declare.

A registered address service is also useful for founders who intend to work from home eventually or from a co-working space that does not permit registration, or who simply want to keep their residential address off the public ACRA record. The registered office address is publicly searchable on the company’s BizProfile, so many directors prefer a dedicated corporate secretary address over a home address for privacy reasons alone.

There is a second, less obvious group who benefit from a registered address service: founders who already have a Singapore office but whose lease or licence agreement does not permit third-party mail collection, or whose landlord will not consent to business registration at the unit. Serviced offices, hot-desking arrangements, and short-term leases can all fall into this category. Rather than risk a rejected BizFile+ filing or a later dispute with a landlord, many founders simply pair their working space with a separate, compliant registered office address supplied by their corporate secretary. This keeps the operational and statutory addresses cleanly separated and avoids friction with the property owner.

Foreign founders should also note that appointing a local corporate secretary who provides the registered address is often the same appointment that satisfies the statutory requirement for a company to have a qualified company secretary within six months of incorporation. Bundling the registered address, the company secretary appointment, and the nominee or resident director arrangement (where needed) with one provider is usually the most efficient route for someone incorporating from overseas without ever having set foot in Singapore.

Eligibility and requirements for a registered address

ACRA’s requirements for a registered office are straightforward but strictly enforced:

• The address must be a physical location in Singapore, accessible to the public for at least three hours during ordinary business hours on each business day.
• A Post Office Box (PO box) alone cannot be used as the registered office address.
• If a residential address is used (for example, an HDB flat or private landed property), the director must first obtain the relevant approval, from the Housing and Development Board for HDB flats, or the Urban Redevelopment Authority for private residential and other zoned properties, before it can be used to carry on a business or as a registered office.
• The address must be able to receive and sign for statutory correspondence, including notices from ACRA, IRAS, and the Ministry of Manpower (MOM), where relevant.

Founders sometimes assume a rented desk in a shared office automatically qualifies. It usually does, but confirm with the provider that the address is licensed for business registration purposes and that mail handling is included, since this is exactly the kind of detail that trips up first-time filers on their Singapore registered address and BizFile+ filings.

Another eligibility point that catches out foreign founders is that the registered office does not need to be occupied by the company itself; it simply needs to be a location where the company’s records can lawfully be kept and where correspondence can be received on the company’s behalf. This is precisely why third-party registered address services, offered by law firms, accountancy practices, and corporate secretarial firms, are both common and fully compliant, provided the provider is genuinely operating from that address and is contactable during business hours. ACRA does, from time to time, conduct spot checks on registered addresses that appear to be inactive or unreachable, so it pays to use a reputable, established provider rather than the cheapest option found online.

Cost and timeline: registered address and BizFile+ fees

Numbers matter here, since budgeting wrongly is a common first-time mistake.

• A commercial registered address service from a corporate secretarial provider typically costs from around S$180 to S$400 per year, depending on whether mail scanning, forwarding, and same-day notification are included.
• ACRA’s BizFile+ filing fees are modest: name application is S$15, company incorporation is S$300, and most post-incorporation filings, such as change of registered address or change of company officers, are free or nominally priced (many “change” transactions on BizFile+ carry no fee at all, though some carry a small charge depending on the transaction type).
• Annual return filing via BizFile+ carries its own separate fee, and deadlines are calculated from the financial year end; if you need the full breakdown, see our guide to annual return filing deadlines and fees.
• Processing timelines: a straightforward company name application is typically approved within minutes to one business day; incorporation itself is often completed within one business day of the name being approved and all information being in order; a change of registered address filed correctly on BizFile+ is usually reflected on the public record within one business day.
• Critically, the Companies Act 1967 requires notification of any change in the registered office address within a prescribed number of days of the change taking effect, generally understood in practice as 14 days. Missing this window is one of the most common compliance lapses among newly incorporated companies.

Beyond the address itself, foreign founders should budget for the wider cost of maintaining a compliant company, since the registered address rarely stands alone. A basic corporate secretary retainer, which typically includes the registered address, statutory register maintenance, and annual return preparation, commonly runs from around S$600 to S$1,500 per year for a small private company, depending on the provider and the level of service. Nominee director services, if required because none of the founders are Singapore citizens, permanent residents, or eligible pass holders, add a further cost on top, often in the range of S$2,000 to S$6,000 per year depending on the risk profile of the business. None of these figures are fixed by law; they vary by provider, so founders should always request an itemised quote before committing.

Step-by-step: registering your address and filing via BizFile+

1. Secure your registered address first. Either engage a registered filing agent or corporate secretarial firm that offers an address service, or confirm the HDB/URA approval if using a residential address.
2. Create a Singpass-linked BizFile+ account access, or authorise a filing agent. Most foreign founders without a Singpass will need to appoint a Singapore-registered filing agent (a licensed corporate secretary) to submit the incorporation on their behalf via BizFile+.
3. Complete the incorporation form (Form 45 equivalent within BizFile+), declaring the registered office address, company officers, share capital, and constitution.
4. Submit and pay the BizFile+ fees for name application and incorporation.
5. Receive the electronic certificate of incorporation and BizProfile, which will show the registered address on the public record.
6. Monitor the address ongoing. If you relocate offices or switch providers, file the change of registered office address on BizFile+ promptly, well within the 14-day window described above.

Throughout this process, foreign founders often find that the trickiest step is not the filing itself but coordinating the underlying paperwork: certified passport copies, proof of residential address, and know-your-customer documentation required by the corporate secretarial firm before it will act as filing agent. Anti-money-laundering obligations mean that reputable providers cannot simply accept an incorporation instruction without first verifying the identity of directors and shareholders, so it is sensible to have these documents ready before starting the BizFile+ process rather than scrambling for them once the clock has started on a name reservation, which is only held for a limited period.

Common mistakes and gotchas

• Missing the notification deadline. Founders who move offices or switch corporate secretary providers sometimes forget that the change of registered office address must be filed on BizFile+ within the prescribed period; late notification can attract penalties.
• Using an unapproved residential address. Declaring an HDB flat or private property as the registered office without the necessary HDB or URA approval is a frequent and avoidable error.
• Assuming a PO box will do. It will not; ACRA requires a physical, accessible address.
• Letting mail go unattended. If the registered address is a shared office or virtual address, confirm someone is actually checking for and signing for statutory correspondence, since missed notices from ACRA, IRAS, or MOM can cascade into other compliance failures.
• Overlooking the interaction with your own immigration status. Foreign founders relocating to run the company should plan the registered address alongside their own pass strategy; if you are converting from a Dependant’s Pass or Employment Pass, see our notes on DP/EP and DP LOC conversion routes, common mistakes and rejection reasons, since address and entity structure decisions often need to be made in tandem with your pass application.
• Ignoring group or family office structuring at the outset. Founders setting up alongside a family office or multi-entity structure across the region should also review our decision tree for multi-jurisdiction family office structures across Indonesia and Malaysia before finalising a Singapore registered address strategy.

FAQs

Can I use my home address as the registered office?
Yes, provided you have obtained the necessary approval, from the Housing and Development Board for an HDB flat, or the Urban Redevelopment Authority for private residential property, and the address remains accessible for at least three hours daily during business hours.

What happens if I do not update my registered address in time?
The Companies Act 1967 requires notification of any change in the registered office address within a prescribed number of days; late filing can result in penalties and, in continued non-compliance, further regulatory action by ACRA.

Do I need a Singapore address before I can incorporate?
Yes. A registered office address in Singapore is a mandatory field on the BizFile+ incorporation form and cannot be left blank or filled with an overseas address.

Can a virtual office or co-working space be my registered address?
Generally yes, provided the provider confirms the address is licensed for business registration and that statutory mail will be received and forwarded promptly, and that the premises meet the accessibility requirement during business hours.

Who can file the incorporation and address change on BizFile+ on my behalf?
A licensed Singapore corporate secretarial firm or registered filing agent can file on your behalf, which is especially useful for foreign founders who do not hold a Singpass.
