The ACRA Definition: What a Corporate Service Provider Actually Is
A corporate service provider (CSP) is any person or business that provides specific corporate services to others, as set out under the Corporate Service Providers Act 2024. The definition is built around six activities: forming a corporation or other legal entity for a client ; acting, or arranging for someone else to act, as a director, company secretary, or partner; providing a registered office, business address, or correspondence address; acting or arranging to act as a nominee shareholder; carrying out designated activities in the course of providing accounting services ; and transacting with ACRA on behalf of another person, including filing as a company’s secretary.
That definition is deliberately broad. ACRA itself notes that CSPs “can be law firms, accounting firms, [or] corporate secretarial firms.” What matters is not what the business calls itself, but whether it performs any of those six activities by way of business. A firm offering only bookkeeping, without carrying out any of the six specified services , may sit outside the definition; a firm that handles your annual return or acts as your registered office almost certainly sits inside it.
The Corporate Service Providers Act 2024: what changed and why it matters to businesses that hire one
Before the CSP Act, only businesses that actually filed transactions with ACRA on a customer’s behalf had to register, as Registered Filing Agents (RFAs), and were subject to anti-money laundering obligations. The CSP Act 2024 replaced that narrower framework and widened it considerably: since the Act and its accompanying Corporate Service Providers Regulations 2025 took effect on 9 June 2025, every business entity carrying on the business of providing corporate services in or from Singapore must register with ACRA as a CSP, whether or not it ever files anything with ACRA directly.
Most coverage of the CSP Act focuses on what it means for the providers themselves: registration steps, the new anti-money laundering, countering-the-financing-of-terrorism, and proliferation-financing (AML/CFT/PF) obligations, and the requirement for at least one Registered Qualified Individual (RQI) on staff. Less gets said about what it means for the business hiring one. In practice, it means three things. First, the firm handling your incorporation, secretarial filings, or registered address is now legally required to run customer due diligence on your company, similar to what a bank does when you open an account, so expect to be asked for more documentation than you might have been a few years ago. Second, that same firm is required to vet anyone it arranges to act as a nominee director on your behalf, assessing them as fit and proper before the arrangement goes ahead. Third, and most directly relevant to your own risk: engaging an unregistered provider is not a minor administrative gap on their part, it can leave your filings, registered office, and nominee arrangements sitting on a legally non-compliant foundation.
What ACRA registration means for the firms you are evaluating
Operating as a CSP without registering is a criminal offence, carrying a fine of up to S$50,000, imprisonment of up to two years, or both, with a further fine of up to S$2,500 for each day the offence continues after conviction.. That penalty structure exists because ACRA treats CSPs as a gatekeeper function in preventing money laundering, not merely as a paperwork category. When you are comparing providers, a firm’s CSP registration is the baseline check, not a nice-to-have credential. ACRA’s Bizfile portal includes an entity search that lets you confirm whether a specific business is a registered CSP, which is worth doing before you sign anything rather than after.
What Does a Corporate Service Provider Do?
Company incorporation and business set-up
This is usually the first service a business engages a CSP for: registering a new company with ACRA, preparing the constitution, and, for foreign founders in particular, arranging the local resident director that Singapore’s Companies Act 1967 requires (at least one director must be ordinarily resident in Singapore). . Non-resident founders are generally required to engage a CSP for this step, since Bizfile transactions require Singpass access, which most non-resident founders do not have, so the incorporation must be filled through a registered CSP.
Corporate secretarial and statutory compliance
Every Singapore company must appoint a company secretary, who must be an individual whose principal or only place of residence is in Singapore, within six months of incorporation, and that role carries ongoing statutory duties: filing annual returns, maintaining statutory registers including the Register of Registrable Controllers and the Register of Nominee Director and keeping board and shareholder resolutions in order. A corporate service provider typically holds this function for SMEs and foreign-owned subsidiaries that don’t have an in-house company secretary.
Outsourced accounting, tax filing, and payroll
Many CSPs bundle bookkeeping, GST filing, corporate tax filing, and payroll into the same relationship as the secretarial work, on the reasoning that a company’s statutory and financial compliance calendars overlap enough that separating them across different vendors creates unnecessary coordination risk.
Ongoing advisory and regulatory tracking
Beyond the recurring filings, a capable provider flags changes that affect your company before they become a problem: a Budget announcement that changes a filing threshold, a new AML disclosure requirement, or a deadline shift like the one the CSP Act itself introduced. This is the part of the relationship that’s hardest to evaluate before signing, since it only shows up in how the firm behaves once something changes.
Why Businesses Outsource to a CSP Instead of Managing In-House
Cost and resource efficiency
Hiring a full-time company secretary, bookkeeper, and payroll administrator makes sense for a large organisation; for a startup or SME, that headcount usually costs more than an outsourced engagement covering the same functions, and leaves specialist compliance knowledge concentrated in one or two people rather than spread across a firm.
Compliance accuracy as regulations evolve
Singapore’s corporate compliance rules move: audit exemption thresholds, filing forms, and now the CSP Act itself have all changed in the last several years. A provider whose core business is tracking these changes across many clients is, in practice, more likely to catch a change that affects you than an internal team for whom compliance is one responsibility among several.
Scaling operations without adding headcount
As a company adds entities, enters a new market, or simply grows its transaction volume, the compliance workload grows with it. An outsourced provider can usually absorb that growth within the existing engagement, where an in-house function would need new hires to keep pace.
Five Factors That Separate a Reliable CSP from a Box-Ticker
ACRA registration status and CSP Act compliance
Confirm registration through Bizfile’s entity search rather than taking a website claim at face value. A provider that is registered will have no difficulty pointing you to how to verify it; hesitation here is itself a signal.
Full-lifecycle capability: can they handle everything from incorporation to annual filing?
A box-ticking provider handles the transaction in front of them, your incorporation, say, and stops there. A genuine corporate service provider is built to carry your company through incorporation, the first annual return, ongoing secretarial duties, and the accounting and tax obligations that come with an active trading entity, without you needing to onboard a second vendor six months in.
Experience with your business type, size, or structure
A provider that mostly serves small local trading companies may be less prepared for a foreign-owned subsidiary with a Malaysian holding company and cross-border reporting obligations. Ask directly about their experience with structures similar to yours rather than assuming general competence translates across every scenario.
Responsiveness and a named point of contact
You want to know who specifically is handling your file, not a generic support inbox. A provider that can’t name the person responsible for your account before you’ve even signed is unlikely to improve on that once you’re a client rather than a prospect.
Transparent, written scope with no hidden fees
Get the engagement scope in writing before signing: what’s included, what triggers an extra charge, and how pricing changes if your transaction volume or entity count grows. A verbal assurance that “we’ll sort out the details later” is worth pushing back on.
Questions to Ask Before You Sign an Engagement Letter
Are you registered under the Corporate Service Providers Act 2024?
Ask for the registration directly, and cross-check it yourself on Bizfile rather than relying solely on their answer. This is the single most consequential question on this list, since everything else assumes the provider is operating within the regulated framework in the first place.
Who specifically handles my account and what are their qualifications?
Beyond the named contact, ask whether the individual is a Registered Qualified Individual under the CSP Act, and what professional background they bring to secretarial, accounting, or tax work specifically.
How do you handle regulatory changes that affect my filings?
A strong answer describes a proactive process, how the firm monitors changes and notifies affected clients. A weak answer amounts to “you’ll find out when it’s time to file,” which puts the burden of tracking regulatory change back on you.
What is the process if I need to switch providers?
Ask this before you need the answer. A reasonable provider will describe a clean handover process, including transferring statutory registers and historical records; a provider that’s vague here may make an eventual exit harder than it needs to be.

Frequently Asked Questions
What is the difference between a corporate service provider and a corporate secretary?
A corporate secretary is one specific statutory role: the person or firm formally appointed to fulfil a company’s company secretary duties under the Companies Act. A corporate service provider is the broader regulatory category under the CSP Act, covering any business offering incorporation, secretarial, registered address, nominee director or shareholder, or designated accounting-related, or ACRA-filing services. A registered CSP will often provide the qualified individual who takes up the company secretary appointment; the two terms describe different things, one a role, the other a regulatory status.
Do I need to hire a registered CSP, or can I manage compliance myself?
Company secretarial and filing work can, in principle, be handled internally rather than outsourced, provided your own team has the capacity and know-how, and you’re not relying on someone acting as a nominee director or shareholder. In practice, most SMEs and nearly all foreign-owned entities engage a CSP, partly because incorporation without local ties usually isn’t possible without one, and partly because the compliance calendar is easier to get wrong than most first-time directors expect.
How much does a corporate service provider cost in Singapore?
Pricing depends heavily on which services are bundled: incorporation alone is typically a one-off fee, while ongoing secretarial, accounting, and tax support is usually billed monthly or annually and scales with transaction volume and entity complexity. Get a written, itemised quote rather than a single bundled number, so you can see what you’re actually paying for each function.
What happens if my CSP’s ACRA registration is suspended or cancelled?
Your company’s underlying obligationsfilings, statutory registers, and deadlines) don’t disappear because your provider’s registration lapses, but you would need to move quickly to appoint a new, properly registered provider to avoid missing a deadline in the gap. This is a strong practical reason to check registration status periodically rather than only at the start of the relationship.
Can a corporate service provider manage my Singapore and Malaysia entities together?
Some providers operate across both markets and can coordinate filings for a Singapore parent and a Malaysian subsidiary (or vice versa) under a single relationship, which reduces the coordination overhead of managing two unrelated local firms. If you operate in both jurisdictions, ask specifically about the provider’s presence and experience in each market rather than assuming regional coverage on a website means equal depth in both.
When should I review or switch my corporate service provider?
It is worth reviewing whenever your company crosses a structural threshold (adding a new entity, entering a new jurisdiction, or growing past the point where your current provider’s typical client profile matches your own), and at minimum periodically to reconfirm their CSP registration is still active. A provider that was the right fit at incorporation isn’t guaranteed to still be the right fit three years and several entities later.
