Key Points
- Only an RA (or an AA with an audit qualification) may sign a statutory audit opinion in the Netherlands.
- Wta article 27 reserves PIE statutory audits exclusively for RAs; AAs cannot perform them regardless of their other qualifications.
- The NBA maintains the accountants' register, and using the title "RA" without registration is a criminal offence under the Wab.
- The NBA's 2025 herijking beroepsprofiel proposes converting RA into an education title, with separate professional titles such as financial auditor layered on top.
What is an RA (Registeraccountant)?
The Wab establishes two protected accountancy titles in the Netherlands: the RA and the AA (Accountant-Administratieconsulent). Both titles require registration in the NBA's accountants' register. The RA route requires a WO (university) master's degree, a post-master programme of one to two years accredited by the Commissie Eindtermen Accountantsopleiding (CEA), and three years of supervised practical experience ending with a final practical examination.
Once registered, an RA may apply for a "wettelijke controle" (statutory audit) annotation in the NBA register, provided the RA is employed by or affiliated with an audit firm holding a Wta licence. Wta article 27 adds a further restriction: statutory audits of OOB entities (public interest entities) may only be performed by an RA. An AA with a statutory audit annotation may sign non-PIE statutory audits but is excluded from the PIE segment entirely.
The title carries legal weight beyond professional practice. The Dutch Supreme Court has confirmed that the terms "accountant" and "accountancy" are protected designations. Anyone who uses the RA title or a confusingly similar designation without being registered in the NBA register commits an offence under Wab article 41.
Worked example: Van der Berg Logistics B.V.
Client: Dutch transport and logistics company, FY2025, revenue EUR 19M, Dutch GAAP (RJ) reporter. Van der Berg Logistics requires a statutory audit because it exceeds two of the three size thresholds in BW2 Title 9.
Step 1 — Determine who may sign the opinion
Van der Berg Logistics is not a PIE. Both an RA and an AA with a statutory audit annotation may therefore sign the opinion. The engagement partner, Joost Vermeulen RA, holds the statutory audit annotation in the NBA register and is affiliated with a Wta-licensed firm.
Step 2 — Confirm ongoing eligibility
Vermeulen must hold a valid PE (permanente educatie) portfolio. The NBA requires every RA to complete continuing professional education under the Nadere voorschriften permanente educatie. If Vermeulen's PE obligations are not met, the NBA may suspend the registration, which would invalidate any opinion signed during the suspension period.
Step 3 — Apply Dutch auditing standards
Because the engagement is a statutory audit, Vermeulen applies the COS (Controlestandaarden), which are the Dutch transposition of the ISAs. COS requirements are materially identical to the ISAs, with additional Dutch-specific requirements for anti-money laundering procedures under the Wwft and for SBR/XBRL filing.
Step 4 — Sign the controleverklaring
Vermeulen signs the controleverklaring using his RA title and NBA registration number. The opinion is issued in the name of the Wta-licensed firm, not in Vermeulen's personal name. The controleverklaring explicitly states the standards applied (COS) and references the applicable reporting framework (RJ).
Conclusion: the statutory audit is defensible because the signing partner holds a valid RA title with a statutory audit annotation, the firm holds a Wta licence, and the Dutch-specific requirements layered on top of the ISA-based COS framework are addressed in the audit file.
Why it matters in practice
- Firms occasionally fail to verify at engagement acceptance whether the proposed signing partner's NBA registration and statutory audit annotation remain current. ISQM 1.30 requires the firm's acceptance and continuance policies to address whether the firm can comply with relevant ethical and legal requirements. An opinion signed by an RA whose registration has lapsed is technically invalid.
- The distinction between an RA and an AA for PIE statutory audits under Wta article 27 is sometimes misunderstood within multi-partner firms that employ both RA and AA holders. Engagement allocation procedures must ensure that no AA partner is assigned as engagement partner on a PIE statutory audit, regardless of the AA's experience or seniority.
RA vs. AA
| Dimension | RA (Registeraccountant) | AA (Accountant-Administratieconsulent) |
|---|---|---|
| Education requirement | University (WO) master's degree | Professional (HBO) master's degree |
| PIE statutory audits | Permitted under Wta article 27 | Not permitted, regardless of annotations held |
| Non-PIE statutory audits | Permitted (with annotation) | Permitted (with annotation) |
| Primary practice focus | Audit and assurance | Advisory, compilation, and non-PIE audit |
| CEA core subjects (ECTS) | 90 ECTS | 90 ECTS (identical content to RA) |
The practical difference narrows every year. Since 2013, the CEA has aligned the learning outcomes for both programmes, and the core subject content is identical at 90 ECTS. The remaining gap is the master's degree level (WO versus HBO) and the exclusive PIE audit right. The 2025 beroepsprofiel review may widen the distinction again by discontinuing the AA training pathway that includes certifying competence for statutory audits.

Frequently asked questions
Can an AA perform a statutory audit in the Netherlands?
Yes, but with limits. An AA who holds a statutory audit annotation in the NBA register may sign non-PIE statutory audit opinions. Wta article 27 reserves PIE statutory audits exclusively for RAs. The practical effect is that an AA at a non-PIE-licensed firm faces no restriction, while an AA at a PIE-licensed firm cannot sign PIE engagements.
What happens if someone uses the RA title without being registered?
Wab article 41 prohibits the use of the titles "RA," "accountant," or confusingly similar designations by anyone not registered in the NBA's accountants' register. The prohibition extends to business names. The Dutch Supreme Court has confirmed that the term "accountancy" is equally protected. Violations are prosecutable offences, and the NBA actively monitors for unauthorised use.
Will the RA title change under the NBA's 2025 beroepsprofiel review?
The NBA's herijking beroepsprofiel proposes converting RA into an education title rather than a professional title. Under the proposed model, professional titles such as "financial auditor" or "ESG-auditor" would sit on top of the RA education qualification. If adopted, the RA designation would still indicate the education pathway completed, but the professional title would signal current practice competence.
