FTA Tax Audit Triggers and Limitation Periods

Executive Summary

The Federal Tax Authority (FTA) possesses broad discretionary powers to initiate tax audits based on risk assessment, compliance indicators, or specific triggers such as discrepancies in returns, refund claims, or information from third parties. The standard limitation period for tax assessments is five years from the end of the relevant Tax Period, extending to fifteen years in cases involving fraud, tax evasion, or failure to submit a Tax Return [Federal Decree-Law No. 28 of 2022, Articles 42 and 45].

Legal Basis

  • Federal Decree-Law No. 28 of 2022 on Tax Procedures (Articles 17-20, 42, 45)
  • Cabinet Decision No. 74 of 2023 on the Executive Regulation of Federal Decree-Law No. 28 of 2022
  • Cabinet Decision No. 75 of 2023 on Administrative Penalties for Violations
  • Federal Decree-Law No. 47 of 2022 on Corporate Tax (compliance obligations)

Analysis

Audit Triggers

The FTA may conduct a Tax Audit at its discretion to verify compliance with tax legislation. Common triggers include:

  • Inconsistencies or errors in Tax Returns
  • Significant variances between reported figures and third-party data
  • Voluntary Disclosures indicating prior non-compliance
  • Refund applications requiring verification
  • Risk-based selection through FTA's compliance programs
  • Information received from other government authorities or international exchange mechanisms
The Authority is not required to disclose specific reasons for initiating an audit [Federal Decree-Law No. 28 of 2022, Article 17].

Audit Process Requirements

The FTA must provide written notification before conducting an audit, except in urgent circumstances. Key procedural elements include:

  • Minimum five business days advance notice for standard audits
  • Authority to access premises, records, and interview personnel
  • Power to request documents and information from the Taxable Person or third parties

Key Requirements

Standard Limitation Period (5 Years):

  • Applies to Tax Assessments and Tax Audits

  • Calculated from the end of the relevant Tax Period

  • FTA must issue assessment within this timeframe


Extended Limitation Period (15 Years):
  • Tax evasion or fraud cases

  • Failure to submit a required Tax Return

  • Calculated from the end of the Tax Period in which the violation occurred


Record Retention Obligation:
  • Taxable Persons must retain records for seven years following the end of the relevant Tax Period [Federal Decree-Law No. 28 of 2022, Article 56]


> ⚠️ Important: The 15-year extended period applies automatically where the FTA determines fraud or evasion occurred—no prior notification is required before invoking this extended timeframe.

Critical Considerations

Voluntary Disclosure Impact:

  • Filing a Voluntary Disclosure does not prevent an audit but may reduce penalties

  • Disclosure must be made before FTA notification of audit to qualify for penalty mitigation


Penalties for Non-Cooperation:
  • Failure to provide requested information: Administrative penalties under Cabinet Decision No. 75 of 2023

  • Obstruction of audit: Potential criminal referral under Article 25 of Federal Decree-Law No. 28 of 2022


Practical Timeline:
  • For Corporate Tax periods starting 1 June 2023, the earliest standard limitation expiry would be 30 June 2029 (assuming calendar year-end)

  • Records from first CT period should be retained until at least 2031


> 💡 Note: The FTA increasingly uses data analytics and cross-referencing with VAT records, customs data, and banking information to identify audit targets—maintaining consistent reporting across all tax types is essential.
