Estonia

As a member of the European Union (EU), Estonia is subject to accounting, auditing, and financial reporting requirements established in EU Regulations and Directives as transposed into national law. The statutory framework is primarily governed by the Accounting Act and the Auditors Activities Act, together with applicable company, capital markets, and financial sector legislation.

The Accounting Act establishes the legal framework for the preparation and filing of annual financial statements for all registered entities. All legal entities are required to prepare annual accounts and a management report and submit these to the Commercial Register within six months of the end of the financial year. Recent amendments have further aligned the framework with EU sustainability reporting and company size threshold requirements.

With respect to financial reporting standards, Estonia applies International Financial Reporting Standards (IFRS Accounting Standards) as adopted by the EU in accordance with Regulation (EC) No 1606/2002. EU-endorsed IFRS are mandatory for the consolidated financial statements of entities whose debt or equity securities are admitted to trading on a regulated market, as well as for credit institutions, insurance undertakings, and certain other regulated financial entities. Other entities may elect to apply EU-endorsed IFRS voluntarily.

Entities not applying EU-endorsed IFRS prepare financial statements in accordance with the Estonian Financial Reporting Standard, commonly referred to as Estonian Generally Accepted Accounting Principles (Estonian GAAP). These standards are issued by the Estonian Accounting Standards Board under the Ministry of Finance framework. Estonian GAAP is based on the IFRS for Small and Medium-sized Entities and has historically incorporated limited jurisdiction-specific modifications and disclosure simplifications.

The statutory audit framework is established under the Auditors Activities Act, which transposes the EU Statutory Audit Directive and related audit reform requirements into national legislation. The Act regulates the approval, registration, supervision, and discipline of sworn auditors and audit firms and establishes the legal basis for mandatory audits and reviews. Mandatory audit and review requirements apply to public interest entities and to other entities meeting prescribed size thresholds, which were recently revised upward through legislative amendments.

Audits in Estonia are required to be conducted in accordance with International Standards on Auditing (ISA) as issued by the International Auditing and Assurance Standards Board and given legal effect through translation and approval for use in the jurisdiction. The Estonian Association of Auditors supports the translation and implementation of ISA, including the standards applicable for audits on or after 15 December 2023.

In Estonia, the regulated segment of the profession is the statutory audit profession. The legal framework is established by the Auditors Activities Act (AAA), which governs the approval, registration, supervision, and discipline of sworn auditors and audit firms, and provides the legal basis for public oversight, quality assurance, investigation and discipline, and the auditors’ activities register.

Public oversight is exercised by the Auditing Activities Oversight Board (AAOB), which is established under the AAA and operates within the public oversight framework supported by the Ministry of Finance. The AAOB is responsible for organizing and directing public oversight; quality assurance reviews; disciplinary proceedings; complaint investigations; oversight of continuing professional development; the professional examination process; the award and deprivation of the sworn auditor qualification; and the issuance, suspension, restoration, and revocation of activity licenses.

The Estonian Association of Auditors (EAA) is the legally recognized self-governing professional accountancy organization for the audit profession and is established as a legal person in public law. Its responsibilities include promoting audit quality and professional integrity, supporting the development of professional practice, organizing continuing professional development, and safeguarding the professional rights of its members. Membership in the EAA is mandatory for sworn auditors and audit firms.

Entry into the profession is established at the jurisdiction level under the AAA. Candidates for the sworn auditor qualification must hold at least a bachelor’s degree or equivalent recognized higher education qualification, complete a minimum of three years of supervised practical experience, satisfy fit and proper requirements, and successfully pass the professional examination. Upon qualification, the individual must take the sworn auditor’s oath before the AAOB and become a member of the EAA.

The AAA also requires sworn auditors to maintain professional competence through continuing professional development. The requirement is monitored over a rolling three-year period, with part of the training to be completed through programs organized by the EAA. The AAOB oversees compliance with these requirements and may require additional assessment where deficiencies in competence are identified.

The regulatory framework also reflects Estonia’s implementation of the European Union audit reform measures. In addition to the AAA, audits of public interest entities are subject to the requirements of Regulation (EU) No 537/2014. This includes mandatory audit firm rotation requirements, restrictions on the provision of prohibited non-audit services, and enhanced independence requirements applicable to statutory auditors and audit firms conducting audits of public interest entities.

Independent public oversight of the audit profession in Estonia is established under the Auditors Activities Act (AAA), which provides the legal framework for the regulation and supervision of sworn auditors and audit firms.

The Auditing Activities Oversight Board (AAOB) is the audit oversight authority in the jurisdiction. Under the AAA, the AAOB is responsible for key public oversight functions relating to the profession, including decisions on professional qualification and deprivation of qualification, licensing matters, quality assurance, investigations, disciplinary proceedings, complaint handling, and oversight of in-service training. The AAA also provides that the AAOB organizes the translation of international standards and other documents relating to audit activities.

The AAOB operates within Estonia’s statutory public oversight framework and is supported by safeguards intended to reinforce its independence. Members are appointed by the minister responsible for the policy area, based on nominations from public authorities including the Financial Supervision Authority (FSA), the National Audit Office, and the Ministry of Justice and Digital Affairs. The AAA also sets qualification and independence requirements for members of the AAOB.

The Estonian Association of Auditors (EAA), referred to in the AAA as the Board of Auditors, is a self-governing professional association and legal person in public law. The AAOB functions within this statutory framework, while the EAA cooperates with competent authorities, supports oversight activities, organizes in-service training, and represents the profession internationally. This reflects a shared institutional model in which statutory oversight is exercised through the AAOB under the AAA, with professional support functions carried out by the EAA.

Estonian Auditors' Association

The Estonian Association of Auditors (EAA) is the only legally recognized professional accountancy organization for the statutory audit profession in Estonia and is established as a legal person in public law under the Auditors Activities Act (AAA). Membership in the EAA is mandatory for all sworn auditors and licensed audit firms authorized to practice in the jurisdiction.

The EAA serves as the principal professional body for the audit profession and operates within a shared regulatory framework alongside the Auditing Activities Oversight Board (AAOB). Its responsibilities include supporting the development of professional practice, organizing continuing professional development programs for members, contributing to the implementation of auditing and ethical standards through translation and technical guidance, promoting audit quality, and representing the profession in dialogue with public authorities, regulators, and other stakeholders.

In addition to its regulatory support role, the EAA contributes to public policy discussions affecting the profession and the broader corporate reporting framework in Estonia, including matters related to audit quality, financial reporting, and professional standards. It also facilitates professional networking, technical exchange, and training activities for sworn auditors and audit firms.

The EAA is a member of the International Federation of Accountants (IFAC) and an associate member of Accountancy Europe, through which it contributes to regional and international professional dialogue and standard implementation initiatives.

The Auditors Activities Act (AAA) establishes the legal basis for the quality assurance review system in Estonia and assigns responsibility for organizing and carrying out reviews to the Auditing Activities Oversight Board (AAOB). The system applies to sworn auditors and audit firms performing statutory audits and operates on a risk-based cycle, with reviews required at least once every six years and at least once every three years for audit firms that audit public interest entities.

The Estonian Association of Auditors (EAA) has indicated that the jurisdiction-level framework is aligned with the main requirements of Statement of Membership Obligations 1 (SMO 1), and the review cycle and public oversight arrangements are consistent with European Union statutory audit requirements.

Based on the current evidence available, Estonia’s quality assurance system is assessed as Adopted under the 2026 definitions because a quality assurance review system is established and operational for all mandatory audits. International Standard on Quality Management (ISQM) 1 and ISQM 2 have been translated by the EAA and published in Estonian in July 2025, supporting the quality management framework applicable in the jurisdiction.

Current Status: Adopted

The Auditors Activities Act (AAA) establishes the initial and continuing professional development requirements for statutory auditors in Estonia. Candidates for the sworn auditor qualification must hold at least a bachelor’s degree or equivalent recognized higher education qualification, complete a minimum of three years of supervised practical experience, satisfy fit and proper requirements, and successfully pass the professional examination. Professional examinations are organized within the jurisdictional oversight framework, with the Estonian Association of Auditors (EAA) supporting the development of examination content and monitoring outcomes.

The AAA also establishes continuing professional development requirements. Sworn auditors are required to complete 40 academic hours of continuing professional development annually, including training organized or recognized by the EAA. Compliance is monitored through the jurisdiction-level oversight framework.

The EAA reports that the Estonian university education system, professional examination framework, practical experience requirements, and continuing professional development requirements are aligned with the International Education Standards (IES), including IES 7 and IES 8, for the regulated audit profession. IFAC’s current Estonia jurisdiction profile continues to assess the status of IES as Adopted.

Accordingly, the jurisdiction-level framework for statutory auditors is assessed as aligned with the relevant requirements of Statement of Membership Obligations 2 (SMO 2) and the IES in effect at the time of assessment. IES are assessed as Adopted.

Current Status: Adopted

The Auditors Activities Act (AAA) establishes the legal basis for auditing standards in Estonia and provides that audit activities must be performed in accordance with international standards given legal effect in the jurisdiction. The Auditing Activities Oversight Board (AAOB) is responsible for organizing the translation of international standards and other audit-related documents, while the Estonian Association of Auditors (EAA) publishes the applicable Estonian-language standards for use in practice.

The EAA’s current standards page indicates that Estonia has adopted the full set of International Standards on Auditing (ISA) applicable to audits of financial statements for periods beginning on or after 15 December 2024. The published standards include, among others, ISA 220 (Revised), ISA 250 (Revised), ISA 260 (Revised), ISA 315 (Revised 2019), ISA 540 (Revised), ISA 570 (Revised), ISA 600 (Revised), ISA 700 (Revised), ISA 705 (Revised), ISA 706 (Revised), and ISA 720 (Revised), together with related conforming amendments. Accordingly, ISA in Estonia are assessed as Adopted under the 2026 definitions.

In addition, the International Standard on Auditing for Audits of Financial Statements of Less Complex Entities (ISA for LCE) has also been adopted and published by the EAA for use in the jurisdiction.

Current Status: Adopted

Ethical requirements for statutory auditors in Estonia are established under the Auditors Activities Act (AAA), which requires sworn auditors to comply with the International Code of Ethics for Professional Accountants (including International Independence Standards) (the Code).

The Auditing Activities Oversight Board (AAOB) has legal responsibility for ethical standard-setting within the jurisdiction. In practice, the Estonian Association of Auditors (EAA) is responsible for translating and publishing the Code for application in Estonia and supports implementation through technical guidance and training.

The EAA has published the 2025 Estonian translation of the Code, including the international independence standards, on its professional standards page. EAA also maintains an ongoing process to incorporate updates to the Code into national requirements. Accordingly, the Code in Estonia is assessed as Adopted under the 2026 definitions.

Current Status: Adopted

Public sector accounting requirements in Estonia are established by the Ministry of Finance through the General Rules for State Accounting (GRSA), which apply to the state, state accounting entities, and other public sector entities within the scope of the framework. The GRSA provide that the rules are based on accounting principles generally accepted in Estonia and on the International Public Sector Accounting Standards (IPSAS).

The GRSA do not adopt IPSAS directly and in full. Instead, they establish national accrual-based public sector accounting requirements that draw on Estonian generally accepted accounting principles and IPSAS, while also containing jurisdiction-specific rules and departures where the GRSA prevail. Estonia’s Ministry of Finance also states that public sector annual accounts are prepared on an accrual basis and that the Estonian financial reporting standard is based on internationally acknowledged financial reporting standards, including IPSAS.

Accordingly, IPSAS in their entirety have not been adopted for all public sector entities. On that basis, IPSAS in Estonia are assessed as Partially Adopted under the 2026 definitions

Current Status: Partially Adopted

The Auditors Activities Act (AAA) establishes the legal basis for the investigative and disciplinary (I&D) system for statutory auditors in Estonia. The Auditing Activities Oversight Board (AAOB) is responsible for investigations, complaint handling, disciplinary proceedings, and the imposition of sanctions within the jurisdictional oversight framework. The AAA also provides for appeal of disciplinary penalties to the Administrative Court of Tallinn and for public disclosure of penalties through the auditors activities register.

The Estonian Association of Auditors (EAA) has reported that the AAOB’s procedures for investigations of complaints and disciplinary proceedings, updated effective 2021, are aligned with the main requirements of Statement of Membership Obligations 6 (SMO 6). The EAA has also noted that, while certain administrative elements such as formal written timeframe targets, case-tracking procedures, and independent review of complaints with no follow-up are not specifically codified, the AAOB is able to carry out these functions where needed.

Accordingly, the jurisdiction-level framework is assessed as aligned with the relevant requirements of SMO 6, and I&D in Estonia is assessed as Adopted under the 2026 definitions.

Current Status: Adopted

International Financial Reporting Standards (IFRS Accounting Standards) as adopted by the European Union are established in Estonia through the Accounting Act (AA) and directly applicable European Union law. Under the AA, entities whose securities are admitted to trading on a regulated market in Estonia or another European Economic Area contracting state, as well as credit institutions, financial holding companies, mixed financial holding companies, investment firms, and insurance undertakings, are required to apply the directly applicable standard in their financial reporting.

This means that IFRS Accounting Standards are required for all domestic publicly accountable entities within the scope identified in Estonia’s legal framework, which is consistent with the 2026 definition of adoption at the jurisdiction level. Although European Union endorsement may include limited carve-outs at the European level, the IFRS Foundation’s jurisdiction materials continue to treat European Union-endorsed IFRS as the applicable jurisdictional framework for member states, and Estonia’s national law extends that framework to the relevant publicly accountable entities noted above.

Other entities may prepare financial statements either in accordance with EU-endorsed IFRS or the Estonian financial reporting standard. The Estonian financial reporting standard is issued through Accounting Standards Board guidelines and is based on internationally accepted accounting and reporting principles, but it is a national framework rather than IFRS in full.

Accordingly, the jurisdiction-level framework is aligned with the relevant requirements of Statement of Membership Obligations 7 (SMO 7) for publicly accountable entities, and IFRS in Estonia are assessed as Adopted under the 2026 definitions.

International Financial Reporting Standard for Small and Medium-sized Entities (IFRS for SMEs Accounting Standard) is not adopted in Estonia. Instead, Estonian national standards are based on IFRS for SMEs with jurisdiction-specific differences, and in areas not covered by the national standards, IFRS for SMEs is recommended rather than mandatory.
