A revolution in auditing small businesses: The ISA for LCE standard is coming

27. 2. 2026

The auditing environment in the Czech Republic is undergoing a major transformation in 2026. Alongside a significant increase in thresholds for mandatory audits, the long-awaited international standard ISA for LCE (International Standard on Auditing for Less Complex Entities) comes into effect. This regulation represents a historic milestone: for the first time, auditors have a standalone tool designed specifically for less complex entities.

Why is this change happening?
Traditional International Standards on Auditing (ISA) have been increasingly criticized for growing complexity. They were written primarily for the audits of large multinational corporations and banks, which created excessive administrative burdens for smaller family businesses or local companies. ISA for LCE addresses this issue – it is a “leaner” version of the audit, focused on what truly matters while maintaining the same quality of the auditor’s opinion.

Key benefits and limitations
The standard is based on the principle of reasonable assurance. This means the audit opinion has the same weight for banks, investors, and authorities as an audit performed under the full ISA. The main differences include:

  • Reduced bureaucracy: The auditor focuses on real risks of the business, not on complex control mechanisms that small firms often don’t have.
  • Greater clarity: The standard is structured logically according to the audit process (from planning to reporting), improving communication between auditor and client.

However, use of the standard is strictly limited. It cannot be applied by public interest entities (e.g., banks, insurance companies, listed companies) or by firms with complex organizational structures or complicated business models.

What does this mean for companies in 2026?
If your company meets the criteria for a mandatory audit (with thresholds also rising from 1 January 2026), the auditor may choose this modern approach in agreement with you. The result will be a more efficient process that better reflects your business reality. The audit report will explicitly state that it was prepared in accordance with the ISA for LCE standard.
