RFA vs. CSP in Singapore:
Why Your Choice of Provider Matters in 2026

In the world of Singapore business consultancy, people often use acronyms like RFA and CSP interchangeably, but in 2026, you must understand this distinction to protect your company legally.

While they both operate within the corporate services sector, one defines the firm’s legal authorization, while the other defines the individual’s professional qualification. Under the Corporate Service Providers Act, if you hire a firm without these credentials, ACRA may reject your filings.

To put it simply: An RFA (Registered Filing Agent) is the “entity” or the business itself, while a CSP (Corporate Service Provider) is the broader category of the professional service being offered, often led by a Qualified Individual (QI).

1. Registered Filing Agent (RFA)

An RFA is a firm or business entity that ACRA (Accounting and Corporate Regulatory Authority) has officially registered  to provide corporate secretarial services.

• The Power to File: Only an RFA has the legal authority to lodge documents (like Annual Returns or Director changes) on behalf of a client via the BizFile+ portal.
• Regulatory Oversight: RFAs are strictly regulated. They must implement strong Anti-Money Laundering (AML) and internal control policies.
• Entity Level: Think of the RFA as the “License” held by the company.

2. Corporate Service Provider (CSP)

The industry uses the term CSP for firms that provide these services. However, as of 2026, the law now requires every CSP to register as an RFA if they are performing filing tasks.

• The Professional Category: A CSP provides a suite of services including incorporation, tax planning, and governance advisory.
• The “Qualified Individual” (QI): Every RFA must have at least one Qualified Individual. This person holds a recognized professional qualification (e.g., Chartered Accountant or Chartered Secretary).
• Individual Level: The QI is the person responsible for ensuring the RFA acts ethically and legally.

In 2026, ACRA has intensified its “Know Your Customer” (KYC) requirements. If you hire an individual freelancer who is not part of a Registered Filing Agent (RFA), your company risks being flagged.

1. Protection Against “Phantom” Filers

By ensuring your provider is an RFA, you are guaranteed that they have undergone a “fit-and-proper person” test by the Singapore government. This protects your sensitive corporate data.

2. Professional Accountability

Because an RFA must be led by a QI (like a Chartered Accountant), you have a path for recourse if a mistake is made. These professionals follow a strict code of ethics

3. Seamless Integration with AI Tools

In 2026, most RFAs use API-linked software that connects directly to ACRA. Only authorized RFAs can use these AI-powered tools to automate your compliance
