With the introduction of UAE Corporate Tax, businesses are now required to maintain proper financial records and, in many cases, undergo a corporate tax audit. Many companies mistakenly believe audits apply only to large businesses or mainland companies. In reality, corporate tax audit requirements in UAE apply to both mainland and free zone entities, depending on their structure and tax position.
This guide explains who needs a tax audit, when it is required, and how to stay compliant.
What Is a Corporate Tax Audit in UAE?
A corporate tax audit is an independent examination of a company’s financial statements and tax computation to confirm compliance with UAE Corporate Tax Law and Federal Tax Authority (FTA) regulations.
The audit ensures:
- Correct calculation of taxable income
- Proper application of exemptions and reliefs
- Accurate tax filings
Who Must Comply With Corporate Tax Audit Requirements?
Mainland Companies
All mainland companies registered in the UAE must:
- Maintain audited financial statements
- File corporate tax returns

Free Zone Companies
Free zone companies must comply if they:
- Claim 0% qualifying free zone tax rate
- Earn income from mainland UAE
- Are part of a group structure
- Are requested by the FTA
Important:
Free zone status does NOT eliminate audit requirements.
Foreign Companies & Branches
Foreign entities operating in UAE through:
- Branch offices
- Permanent establishments
must also meet corporate tax audit obligations.
