Financial statement audit is obligation affecting many companies. However, not all firms must undergo audit. Learn 2026 limits, three-threshold criteria, and audit procedure.

Who Must Undergo Financial Statement Audit?

The obligation to audit financial statements stems from accounting law and affects certain entities. The list does not depend solely on size or legal form — there are certain exceptions and rules.

Entities Always Obligated (Regardless of Limits)

Some entities ALWAYS must undergo audit, regardless of revenue or employee count:

  • Banks and cooperative banks
  • Cooperative savings and credit unions (SKOK)
  • Financial institutions (finance companies, leasing firms)
  • Insurance and reinsurance companies
  • Joint-stock companies (S.A.)
  • Listed companies

Three-Threshold Criterion for Other Firms

For limited liability companies, partnerships, and civil associations, audit obligation depends on meeting at least TWO of three criteria:

Three Characteristics in Three-Threshold Criterion

Characteristic 2026 Limit Base (EUR)
Total Assets 13,208,437.50 PLN Minimum 7.5 million EUR
Revenue from Sales (net) 26,416,875 PLN Minimum 15 million EUR
Average Number of Employees 250 employees Does not change

If company met at least TWO of three characteristics, it must undergo audit for previous fiscal year. Exceeding limits in prior year determines audit requirement.

Practical Example

LLC had in 2025: assets 10 million PLN, revenue 25 million PLN, 180 employees. Meets 2 characteristics (revenue exceeds limit, assets below). Must undergo audit for 2025 in 2026.

2026 Limits — Exchange Rate Conversion

Limits change yearly. For 2026 they were converted at average NBP rate from end of 2025, which was 4.2579 PLN per EUR.

2026 Limit Conversion

Total Assets: 7,500,000 EUR × 4.2579 = threshold 13,208,437.50 PLN
Revenue: 15,000,000 EUR × 4.2579 = threshold 26,416,875 PLN
Employees: 250 persons (unchanged)
