A company’s financial statements are not only used for internal management decisions; they also serve as a reliable information source for shareholders, investors, lenders, public authorities and other stakeholders. For this reason, companies that reach a certain size, operate in regulated sectors or become subject to specific legal obligations may be required to have their financial statements reviewed by an independent auditor. Independent audit services help assess whether a company’s financial structure complies with applicable legislation, financial reporting standards and auditing principles.
In Türkiye, whether a company is subject to independent audit is determined within the framework of the Turkish Commercial Code, Public Oversight Authority regulations and the relevant Presidential Decisions. Companies should not view this process solely as a reporting obligation. When managed correctly, independent audit strengthens financial transparency, improves the reliability of corporate decisions and supports the company’s position in investment, financing, merger, acquisition or restructuring processes.
What Is an Independent Audit Service?
An independent audit service refers to the objective review of a company’s financial statements, accounting records and related disclosures by authorized independent auditors. The purpose of this process is to determine whether the company’s financial statements are accurate, reliable, comparable and compliant with the applicable financial reporting standards. The audit process is not limited to checking figures; revenue and expense records, balance sheet items, internal control procedures, risk areas, footnote disclosures and management representations are also examined in detail.
This service provides financial assurance to company management and third parties. Within the scope of independent and special purpose audit services offered by STB CPA Turkey, financial statement audits, assurance services, compliance audits, operational audits and corporate reporting processes can be handled with an integrated approach. As a result, companies not only meet their legal obligations but also improve the quality and sustainability of their financial reporting structure.
What Does Independent Audit Obligation Mean for Companies?
For companies, independent audit obligation means that businesses meeting certain criteria must have their financial statements audited by authorized independent audit firms. This obligation ensures that financial information is not limited to internal company declarations but is reviewed through an independent and impartial assessment. Factors such as total assets, annual net sales revenue, number of employees, field of activity or public interest entity status may determine whether this obligation arises.
The main purpose of this obligation is to provide shareholders, investors, creditors, public authorities and other stakeholders with access to accurate financial information. For companies subject to independent audit, the reliability of financial statements increases and management decisions are built on stronger data. According to the Public Oversight Authority, companies subject to independent audit are determined based on relevant decisions, lists and threshold values; criteria such as total assets, net sales revenue and number of employees play an important role in this assessment.
Which Companies Are Required to Undergo Independent Audit?
Independent audit is not automatically mandatory for every company. In Türkiye, companies falling within this scope are determined according to their field of activity, public interest entity status, relationship with capital markets or whether they exceed specific financial thresholds. In particular, companies that exceed certain criteria such as total assets, annual net sales revenue and number of employees in consecutive accounting periods may become subject to independent audit. Therefore, companies should evaluate not only their current year data but also previous accounting periods.
Some companies may be directly included in the audit scope due to their activity area or legal status, while others become subject to audit when they exceed the applicable threshold values. The Public Oversight Authority’s decisions and frequently asked questions set out the framework for calculating total assets, annual net sales revenue and number of employees for companies that will be subject to audit for the first time. For this reason, growing companies should regularly analyze whether they fall within the scope of independent audit.
What Are the Independent Audit Criteria?
Independent audit criteria refer to the main indicators used to determine whether a company is subject to audit. These criteria generally include total assets, annual net sales revenue and number of employees. For some company groups, additional factors such as field of activity, publicly held status, regulatory obligations or public interest entity status may also be considered. In assessing these criteria, not only the company’s standalone financial data but also the economic size created together with subsidiaries and affiliates may be relevant. Therefore, calculations in group companies must be carried out carefully. To avoid incorrect assessments, financial statements, payroll data and shareholding structures should be reviewed together. At this point, STB CPA Turkey can support companies by performing a scope analysis and clarifying whether an audit obligation has arisen.
How Does Company Size Affect Independent Audit Obligation?
Company size is one of the direct factors that determine whether an audit obligation arises. Small-scale companies with limited business volume may often remain outside the independent audit scope, while companies with increasing sales volume, growing asset size or higher employee numbers may become subject to audit. The key issue is not only the company’s growth but also how this growth intersects with the thresholds specified in the legislation. Especially for fast-growing companies, not being subject to audit in the previous year does not necessarily mean that the company will remain outside the scope in the following year. Therefore, company size should be analyzed regularly and financial growth should also be monitored from an audit obligation perspective. Misinterpreting company scale may delay the audit process and create compliance risks.
When Does Independent Audit Obligation Begin?
Independent audit obligation arises when the company meets the scope and threshold values specified in the relevant legislation. In general practice, criteria such as total assets, annual net sales revenue and number of employees are evaluated over specific accounting periods. To determine whether a company will be subject to audit for the first time, previous period financial statements, employee data and the impact of subsidiaries or affiliates, if any, are assessed together. Therefore, the obligation does not arise merely by looking at a single year-end figure; it is determined according to the calculation methods set out in the applicable regulations.
Accurately identifying when the obligation begins is critical for managing the audit schedule properly. Auditor appointment, general assembly procedures, preparation of financial statements, arrangement of footnote disclosures and collection of audit evidence all require a structured timeline. Regulations issued by the Public Oversight Authority indicate that the determination of whether a company is subject to audit depends on financial statements from previous years, total assets, net sales revenue and number of employees. For this reason, preparing before the obligation formally arises helps prevent the audit process from being left to the last minute.
How Are Companies Within the Scope of Independent Audit Determined?
Companies within the scope of independent audit are determined by assessing their legal status, field of activity, financial size and number of employees together. Total assets, annual net sales revenue and number of employees form the core data set of the scope analysis. In addition, some companies may be evaluated under different criteria due to the sector in which they operate or the regulatory framework to which they are subject. Companies related to capital markets, certain financial institutions or public interest entities may require special assessment in this context.
In determining audit scope, the company’s data at the parent company level alone may not always be sufficient. When subsidiaries, affiliates and group structures are considered, the likelihood of being included in the audit scope may change. Therefore, companies should conduct periodic independent audit scope analyses.
| Evaluation Area | Reviewed Element | Importance for Audit |
|---|---|---|
| Financial size | Total assets and net sales revenue | Shows whether threshold values are exceeded |
| Human resources | Average number of employees | Indicates the operational scale of the company |
| Group structure | Subsidiaries and affiliates | May change the consolidated effect and audit scope |
| Field of activity | Sector and regulatory obligations | May directly create audit obligation |
Total Assets and Net Sales Revenue Criteria
Total assets and net sales revenue are among the most important financial indicators used to determine audit scope. Total assets show the size of the company’s balance sheet, while net sales revenue reflects business volume and commercial scale. These two criteria are evaluated together to understand the company’s financial capacity and economic impact. In structures with subsidiaries or affiliates, the calculation may become more comprehensive because the economic size within the group may be higher than the company’s standalone financial scale. Therefore, a superficial review of accounting records is not sufficient. When assessing whether a company falls within the audit scope, the accuracy of financial statements, classification structure and group relationships should be analyzed together.
Employee Number Criterion
The employee number criterion is an important indicator of a company’s operational scale and organizational size. In evaluating this criterion, looking only at the number of employees at the end of the period may not always be sufficient; the average number of employees during the period or the impact of related structures may also need to be considered according to the calculation method specified in the relevant regulations. This criterion must be interpreted carefully, especially for companies with seasonal employment, project-based staffing or personnel relationships within group companies. Incorrect calculation of employee numbers may lead to a wrong conclusion about whether the company is subject to independent audit. Therefore, human resources records, payroll data and the company’s organizational structure should be assessed together with financial data. STB CPA Turkey can contribute to this analysis by reviewing finance, accounting and HR data in a coordinated manner.
What Risks Do Companies Face If They Do Not Obtain Independent Audit Services?
Companies that are subject to audit but fail to obtain independent audit services may face legal compliance risks, financial reporting risks and loss of corporate credibility at the same time. Unaudited financial statements may not provide sufficient assurance to shareholders, investors, banks and other stakeholders. This may weaken the company’s reliability in credit negotiations, investment processes, company valuation studies, mergers and acquisitions or commercial agreements. Failure to fulfill the audit obligation on time may also create responsibilities for management bodies.
The risk is not limited to legal non-compliance. Without independent audit, errors, omissions, classification issues or internal control weaknesses in financial statements may be detected too late. This may lead to incorrect decisions in many areas, from cash flow management and tax planning to inventory valuation and debt restructuring. Especially in growing companies, if financial reporting discipline is not established on time, the audit process may become more costly and challenging in later periods. Therefore, audit should be considered not only when it becomes mandatory, but also as a strategic tool when corporate governance needs arise.
How Should Companies Prepare for the Independent Audit Process?
Preparation for the independent audit process begins with making the company’s financial records, accounting policies, internal control structure and supporting documents suitable for audit. At this stage, balance sheet and income statement items, bank reconciliations, current account confirmations, inventory records, fixed asset lists, contracts, litigation and risk provisions, and footnote disclosures should be reviewed. Documents submitted to the audit team should be organized, traceable and consistent. When an audit is initiated without adequate preparation, information requests may take longer, correction entries may increase and the reporting timeline may be delayed.
STB CPA Turkey can support companies during the pre-audit preparation process in terms of financial reporting, accounting structure and document flow. In this context, audit and assurance services create value not only at the reporting stage but also in pre-audit preparation and the identification of risk areas. Early preparation enables companies to respond faster to auditor requests, present financial statements more accurately and manage the process in a more structured way.
What Should Companies Consider When Obtaining Independent Audit Services?
The first factor to consider when obtaining independent audit services is the competence, regulatory knowledge and sector experience of the audit team. Audit is not a mechanical process carried out only through standard checklists; the company’s business model, revenue structure, risk areas, internal control level and reporting needs must be properly understood. Therefore, the audit firm should have strong knowledge of financial reporting standards, Turkish Auditing Standards, relevant Public Oversight Authority regulations and the sector in which the company operates.
Companies should not make their audit service decision based solely on price. The scope of the audit plan, team structure, reporting schedule, communication model, required documentation, approach to critical accounting areas and coordination with management should be clearly evaluated. STB CPA Turkey is positioned as a firm that supports local and foreign investors in tax, financial reporting, accounting, corporate law, social security, payroll, audit and advisory services. This approach ensures that the audit process is handled not only from a legal compliance perspective but also from the perspective of improving the company’s financial management quality.
How Should Companies Manage the Independent Audit Compliance Process?
The independent audit compliance process for companies begins with a scope analysis. First, it should be determined whether the company is subject to audit; then the audit schedule, responsible internal teams, document preparation plan and financial statement closing procedures should be clarified. Finance, accounting, legal, human resources and senior management teams must work on the same timeline. Especially in group companies, timely collection of subsidiary and affiliate data, assessment of consolidation effects and preparation of financial statements for audit are among the most critical parts of the process.
For successful compliance management, companies should not treat audit only as a year-end obligation. Interim checks, internal control reviews, document organization, updates to accounting policies and stronger management reporting make the process healthier. When independent audit in companies becomes part of the corporate governance culture, financial decisions are based on more reliable data. STB CPA Turkey can support companies that are subject to mandatory independent audit or likely to fall within its scope in planning the compliance process, identifying risk areas and managing the audit timeline in a more controlled manner.
