Financial audit of a foreign subsidiary in Poland: statutory audit and IFRS consolidation package

A Polish subsidiary of a foreign group usually faces two separate audit obligations: a statutory audit under Polish law (UoR) and an IFRS consolidation package review for the parent. Understanding both — and managing them efficiently — is the starting point for any finance director or CFO of a Polish entity.

01
The statutory audit under the Polish Accounting Act (UoR) is a Polish law obligation independent of whether the parent requires an IFRS package.
02
Using one auditor for both the UoR audit and the IFRS package review is usually more efficient and reduces coordination overhead.
03
The component auditor role under ISA 600 requires specific coordination with the group auditor — your Polish auditor must understand this framework.
Key takeaway:
A Polish subsidiary of a foreign group typically has two audit obligations: a statutory audit under Polish GAAP (UoR) filed with the National Court Register, and an IFRS or group-GAAP consolidation package submitted to the parent. These are separate engagements with different standards, deadlines and purposes — but they can be managed by a single auditor.

Two separate obligations

Foreign investors setting up or acquiring a Polish subsidiary are sometimes surprised to learn that their Polish entity has two distinct reporting obligations that may each require an auditor:

  1. Statutory audit under the Polish Accounting Act (UoR): Required by Polish law once the entity exceeds the size thresholds in Article 64 UoR. The auditor issues a statutory audit report and opinion. Financial statements are filed with the National Court Register (KRS).
  2. IFRS consolidation package review: Required by the parent group for consolidation purposes. The package is prepared under IFRS, US GAAP or the group's own accounting policies — not Polish GAAP. The auditor reviews or agrees procedures on this package and reports to the group auditor.

The two obligations can exist independently. A subsidiary may require only the statutory audit (if the parent does not require a package), or both (more common in practice).

Statutory audit thresholds (Article 64 UoR)

A Polish entity is required to have its financial statements audited if, in the preceding financial year, it met at least two of the following three thresholds:

ThresholdValue
Balance sheet totalPLN 2,500,000 (approx. EUR 550,000)
Net revenue from salesPLN 5,000,000 (approx. EUR 1,100,000)
Average annual headcount50 full-time equivalents
Note: These thresholds are relatively low. Most Polish subsidiaries of foreign groups — even modest-sized ones — will exceed them and be required to have a statutory audit.

Component auditor role (ISA 600)

When the group auditor issues an opinion on consolidated financial statements, they rely on work performed by component auditors — the local auditors of individual subsidiaries. This relationship is governed by ISA 600 (Standard on the Audit of Group Financial Statements) and its Polish equivalent KSB 600.

The component auditor (JMFC, as the Polish auditor) must:

  • Confirm independence and professional qualifications to the group auditor
  • Execute audit procedures specified in the group audit instructions
  • Report findings in the format required by the group auditor
  • Respond to queries and review requests from the group auditor within the group reporting calendar
Practical point: Some group auditors send very detailed instructions; others send minimal guidance. JMFC is experienced in interpreting group audit instructions and communicating directly with Big Four and mid-tier group audit teams across Europe.

One auditor for both engagements

There is no legal requirement to use the same auditor for the statutory audit and the IFRS package review — but doing so has practical advantages:

  • Single planning process: The auditor understands both the UoR and IFRS positions of the entity and can identify differences (IFRS adjustments) efficiently.
  • Reduced client overhead: One set of fieldwork, one PBC list, one primary contact — rather than coordinating two separate audit teams.
  • Better coordination with the group auditor: A single component auditor provides one consolidated set of findings and one point of contact for the group audit team.
  • Faster delivery: Work performed for the statutory audit (e.g. substantive testing of balance sheet items) is typically reusable for the IFRS package review.

Frequently asked questions

Does a Polish subsidiary of a foreign group need a statutory audit?
Yes, if it meets two of three thresholds under Article 64 of the Polish Accounting Act: balance sheet total above PLN 2.5 million, net revenue above PLN 5 million, or average headcount above 50 FTEs. The obligation is independent of any group audit requirement.
What is the difference between a statutory audit and an IFRS consolidation package review?
The statutory audit covers the Polish GAAP (UoR) financial statements filed with the National Court Register. The consolidation package review covers figures prepared under IFRS or group accounting policies submitted to the parent for consolidation. They are two separate products with different standards, deadlines and addressees.
Can the same auditor perform both the statutory audit and the IFRS package review?
Yes, and this is often the most efficient approach. Using one auditor for both engagements avoids duplication, reduces client-side management effort and enables better coordination with the group auditor under ISA 600.
What is the component auditor's role under ISA 600?
The component auditor performs procedures specified in the group audit instructions and reports to the group auditor. This requires confirming independence, executing specific tests, and providing findings within the group reporting calendar. JMFC has direct experience coordinating with Big Four and mid-tier group audit teams.
