Who Is a Statutory Auditor?
Statutory auditors are public trust professionals. They are responsible for the independent and reliable assessment of a company’s financial statements. They hold special qualifications granted by the Polish Agency for Audit Oversight (Polish: PANA). They are registered on the list of statutory auditors maintained by the Polish Chamber of Statutory Auditors (PIBR).
Statutory auditors evaluate financial statements and internal control systems. They also provide expert advice on accounting matters. Their main goal is to improve the credibility of financial data. This builds trust with investors, business partners, and financial institutions.
According to the Act of 11 May 2017 on statutory auditors, audit firms, and public oversight, a statutory auditor can be:
- An individual running a business in their own name and for their own account,
- A partner in an audit firm authorised to audit financial statements,
- A person with a civil law contract or employment agreement with an audit firm.
When Is an Audit by a Statutory Auditor Mandatory?
Not every entrepreneur is required to undergo an audit. According to the Accounting Act of 29 September 1994, an audit of financial statements is mandatory for entities that meet at least two of the following three criteria:
Criterion | Threshold |
Total assets | 2 500 000 € |
Net sales revenues | 5 000 000 € |
Average annual employment | 50 people |
The EUR amounts must be converted into PLN based on the average NBP exchange rate on the balance sheet date.
Entities required to undergo an audit include:
- joint-stock companies,
- banks and insurance companies,
- investment funds,
- entities benefiting from public subsidies above 3 000 000 PLN,
- other entities that opt for a voluntary audit.

How Does a Statutory Audit Work in Practice?
A statutory audit consists of several stages:
- Audit Planning. The auditor analyses the entity’s structure, risks, and areas requiring special attention.
- Preliminary Audit. It includes a review of documents and verification of accounting systems and procedures.
- Main Audit. The auditor analyses in detail financial data, performs reliability tests, and evaluates the validity of disclosed information.
- Issuing the Auditor’s Opinion and Report. Auditor provides an opinion on the accuracy and legal compliance of the financial statements.
An audit may end with an unqualified opinion or a qualified opinion. Sometimes, the auditor may refuse to issue an opinion. In some cases, a negative opinion is also a possible outcome.
Voluntary Audit – When Is It Worth Considering?
Even if an audit is not legally required, it may be beneficial in the following situations:
- preparing the company for sale,
- applying for a loan or investor funding,
- increasing the company’s transparency for contractors,
- the intention to organise internal financial documentation.
A voluntary audit by a statutory auditor can significantly increase the company’s credibility. It can alsofacilitate its future development.

- Whether the person is listed in the Polish Chamber of Statutory Auditors (PIBR),
- Their experience in the relevant industry,
- Their references and certifications,
- Whether they offer clear terms of cooperation and a transparent schedule.
