What to Do If You Receive the “Declaration Oversight Study” Notice
On April 21, 2025, Turkey’s Tax Inspection Board (“Vergi Denetim Kurulu Başkanlığı”) issued a new preventive compliance initiative called the “Declaration Oversight Study”. Although the notice is not an audit order or a request for explanation, it signals that your corporate tax return for the 2024 fiscal year has been flagged for risk analysis. Ignoring its guidance could trigger a full tax inspection.
Below, we explain:
What the Declaration Oversight Study aims to achieve
Which risk areas are under review
Practical steps to take if you receive this notice
1. Purpose of the Declaration Oversight Study
The Declaration Oversight Study represents a shift toward proactive, risk-based monitoring of corporate tax filings. Through this initiative, the Tax Inspection Board seeks to:
Enhance voluntary compliance by alerting taxpayers to potential pitfalls before formal audit
Identify errors in advance to reduce the incidence of returns that require corrective filings
Allocate inspection resources efficiently by focusing on higher-risk filers
Promote transparency and accountability in the tax-filing process
By treating the notice as an early warning rather than a punitive measure, the Board hopes to minimize disputes and foster a collaborative compliance environment.
2. 2024 Risk Analysis Topics
For the 2024 tax period, the Board has outlined the following risk areas. Your return may be flagged if any of these items appear inconsistent or inadequately documented:
Revenue Recognition
- Ensuring all cash and bank collections are fully reported as gross sales.
Cost of Imported Goods
- Verifying import duties and expenses are appropriately included in cost calculations.
Net Corporate Income Calculation (CTC Art. 6)
- Checking that net taxable profit is computed in line with the Corporate Tax Code.
Loss Offset Transactions (CTC Art. 9)
- Confirming that loss carry-forwards and set-offs comply with statutory conditions.
Deduction Applications (CTC Arts. 8 & 10)
- Reviewing eligibility for deductions claimed under corporate tax provisions.
Non-Deductible Expenses (CTC Art. 11)
- Identifying and excluding expenses that the law does not permit.
Tax Security Mechanisms (CTC Arts. 7, 12, 13)
- Assessing whether required guarantees or securities have been provided correctly.
Exemptions and Incentives
- Validating that exemption criteria (e.g., technopark, free-zone incentives) are fully met.
Tax Base and Liability Calculations
- Ensuring the tax base and total tax liability are accurately computed.
Valuation Procedures (Tax Procedure Law)
- Checking conformity with valuation rules for assets and inventories.
- Inflation Adjustment (Tax Procedure Law)
- Verifying the correct application of inflation accounting methods.
- Other Relevant Issues
- Any additional risk factors identified by the Board, such as industry-specific anomalies.
3. Recommended Actions upon Receiving the Notice
Receiving the Declaration Oversight Study notice need not provoke alarm, but it does demand attention. Follow these best practices:
Avoid Panic, Act Promptly
- The notice itself is not an audit summons—but it indicates your return will be reviewed. Begin your review immediately.
Prepare Complete Workpapers
Compile and organize all supporting schedules, ledgers, and workpapers for the flagged risk areas.
Ensure cross-references between your tax return and source documentation are clear.
Re-examine Critical Calculations
Revisit depreciation schedules, inflation adjustments, and asset valuations.
Double-check cost of goods sold, especially for imported inputs.
Verify Incentive and Exemption Claims
If you’ve claimed reduced rates or tax holidays (e.g., R&D relief, free-zone incentives), confirm all statutory conditions are satisfied.
Document board resolutions, license certificates, or other proof of eligibility.
Engage a Second Review
Have an internal or external tax specialist (e.g., a senior accountant or in-house auditor) scrutinize your return and supporting files.
This fresh perspective can catch oversights before any formal examination begins.
Maintain Open Communication
While you are not required to submit any immediate response to the notice, be ready to answer queries if the Board requests additional information.
Prompt, well-prepared replies can prevent escalation to a full audit.
Conclusion
The Declaration Oversight Study represents Turkey’s move toward a more preventive, risk-based approach to tax compliance. By treating the notice as an opportunity to strengthen your internal controls and documentation, you can minimize the chance of a formal audit and potential penalties.
Should you need assistance reviewing your 2024 corporate tax return or preparing the necessary workpapers, consider engaging qualified tax advisors who specialize in preventive compliance.
