Singapore’s Corporate Service Providers (CSP) Act will commence on 9 June 2025, introducing a mandatory registration regime for businesses that provide corporate and designated accounting-related services.

All existing service providers operating within scope must complete CSP registration with ACRA by 9 December 2025. After this date, only registered CSPs can legally carry out the prescribed activities, whether performed domestically or overseas. This development carries significant compliance, operational, and risk-management implications for accounting firms, outsourced service providers, corporate secretaries, and business service intermediaries.

Scope of Activities Requiring CSP Registration

The Act covers five primary categories of corporate services. Any entity engaging in these activities by way of business must be registered:

1. Formation of Business Entities

• Incorporation or set-up of companies, partnerships, and other legal persons.

2. Acting or Arranging for Persons to Act in Key Roles

• Serving as or procuring:
  • Company directors
  • Nominee shareholders
• Includes intermediary arrangements such as:
  • Providing a shortlist of proposed directors
  • Introducing candidates and charging customers for placement services

3. Transactions with ACRA

• Filing or transacting with ACRA on behalf of clients
• Acting as a company secretary on a commercial basis

4. Provision of Address Services

• Registered office addresses
• Virtual office, shared office, and correspondence address services
• Addresses where the client is not physically present

5. Designated Accounting-Related Activities

A CSP registration is required when engaged in accounting services (e.g., outsourced accounting, internal audit, management accounting, taxation) and carrying out any designated activity, including:

• Preparing or executing transactions for:
  • Buying or selling real estate
  • Managing client money, securities, or assets
  • Managing bank/securities accounts
  • Organising contributions for corporate creation/operation
  • Managing legal persons or arrangements
  • Buying and selling business entities

Exemptions

You do not need CSP registration if you are:

• A landlord leasing a dedicated physical unit as a registered or business address
• An individual acting as director or secretary only for your employer
• An intermediary referring customers to registered CSPs
• A Public Accounting Entity (deemed registered unless filing via Bizfile for clients)

Registration Requirements and Process

Application

• Submission via Bizfile
• Completion of a fit and proper assessment
• Application fee: S$400

Existing Registered Filing Agents (RFAs)

• Automatically treated as registered CSPs
• No application or fee required
• Must update ACRA on the types of corporate services provided

Compliance Deadline

• Service providers currently performing in-scope activities who are not RFAs must register by 9 December 2025
• Operating without registration after this date may result in:
  • Fines up to S$50,000 upon conviction

Implications for Accounting Firms and CSPs

1. Expansion of Regulatory Oversight

The Act extends regulation beyond traditional corporate secretarial functions to encompass designated accounting activities, potentially capturing:

• CFO-as-a-service providers
• Real estate transaction accountants (e.g., preparing completion accounts)
• Firms offering both accounting and transaction execution services

Firms must internally map service lines to determine which workflows constitute designated activities. Hybrid service providers may fall within scope unexpectedly.

2. Operational Restructuring and Documentation

Service providers must establish:

• Documented client onboarding processes
• Clear delineation between “advice-only” accounting services vs. transaction execution
• Updated engagement letters to reflect regulatory obligations

Firms offering “full-service” outsourced accounting (e.g., managing bank accounts, arranging corporate transactions) may need to restructure responsibilities to ensure compliance.

3. Enhanced KYC, AML, and Fit-and-Proper Compliance

With registration comes obligations akin to existing RFA regimes:

• Fit and proper assessments
• Internal AML/CFT controls
• Ongoing monitoring and record-keeping

Practical issue: Smaller or unregulated bookkeeping firms may need to significantly uplift compliance frameworks, which may impose cost and training burdens.

4. Address Service Providers Now Brought Into Regulation

Coworking spaces, virtual office operators, and address providers must consider:

• Whether their service model involves non-dedicated space
• Whether they operate as an intermediary or true landlord

A landlord exemption applies only if a dedicated physical unit is leased with clear tenancy agreements. Virtual office providers must be prepared for CSP registration.

5. Impact on Cross-Border Service Providers

The Act applies even when services are performed outside Singapore for Singapore entities.
Overseas accounting or corporate service firms supporting Singapore companies may need registration.

Foreign service providers may need Singapore compliance support or local partnership structures.

Recommended Actions (Immediate to Pre-June 2025)

1. Conduct a CSP Impact Assessment

• Review service lines and client activities
• Identify if any designated or corporate services are offered
• Determine whether staff or affiliates “arrange for persons to act”

2. Update Client Engagement and Operational Policies

• Introduce internal guidance on in-scope activities
• Update letters of engagement to capture CSP boundaries and responsibilities

3. Assess AML/KYC Readiness

• Strengthen customer onboarding
• Enhance record-retention and risk assessment processes
• Prepare for ACRA inspections

4. Plan for Registration (if required)

• Allocate resources for fit and proper checks
• Prepare documentation for Bizfile application
• Budget for possible compliance uplift

The introduction of the CSP Act represents a major tightening of Singapore’s regulatory framework for corporate and accounting service providers. Accounting firms, outsourced finance teams, virtual office providers, and intermediaries introducing corporate officers should promptly review their service scope to avoid inadvertent non-compliance. Early assessment and operational preparation ahead of the 9 December 2025 deadline will be critical in mitigating regulatory and business risks.
