İzaha Davet in Türkiye: How the Pre-Assessment Tax Explanation Mechanism Works

The Tax Administration of Türkiye (Vergi Dairesi) actively applies the İzaha Davet procedure — an administrative mechanism that allows taxpayers to explain potential tax inconsistencies before a formal tax audit begins.

For foreign entrepreneurs and companies from CIS countries operating in Türkiye, understanding this procedure is crucial. A well-prepared response to an izaha davet notice can significantly reduce the risk of tax penalties and reputational damage.

What Is İzaha Davet

İzaha davet is an official notification sent by the tax authority after a preliminary analysis of a company’s tax data.

If the tax administration detects indications of possible tax irregularities, it first invites the taxpayer to provide an explanation.

This process allows companies to:

• clarify the nature of transactions
• correct reporting errors
• potentially avoid a full tax audit

It is important to note that the procedure is initiated by the tax authority, not by the taxpayer.

When the Procedure Is Applied

An izaha davet notice is issued when the tax authority’s analytical review identifies signs of potential tax loss.

However, there are situations where the procedure is not applied, and a tax audit may begin immediately:

• use of fake or misleading documents (SMİYB) on a significant scale
• if a tax audit regarding the issue has already started
• if the tax authority receives an official complaint or report (ihbar)

In cases involving suspicious invoices or documents, an additional threshold is used.
If the amount does not exceed 700,000 TL or 5% of annual purchases, the tax authority may first request an explanation. If these thresholds are exceeded, a direct audit may be initiated.

Main Stages of the Procedure

1. Submission of Explanation

After receiving the notification, the taxpayer must submit a written explanation within 30 days.

The response can be submitted:

• through Dijital Vergi Dairesi (the digital tax system of Türkiye)
• in paper form through the tax office.

2. Review Process

The explanation and documents are evaluated by a specialized commission:

Pre-Assessment and Explanation Evaluation Commission
(Ön Tespit ve İzah Değerlendirme Komisyonu)

The commission reviews the submitted materials and issues a decision within the administrative timeframe.

Possible Outcomes

Penalty Reduction

If the company voluntarily corrects its tax declaration after receiving the notification, a reduced penalty may apply.

Typically, the penalty may be around 20% of the tax loss, provided that:

• the corrected declaration is submitted within the specified timeframe
• the calculated interest is paid.

If the taxpayer fails to respond or provides incomplete information, the penalty may increase and a full tax audit may follow.

How to Respond Effectively to an İzaha Davet

1. Analyze the Issue

Companies should:

• identify the transactions that triggered the inquiry
• review accounting records
• determine the source of discrepancies.

2. Prepare Supporting Documents

It is important to gather:

• accounting records
• invoices
• contracts
• payment confirmations.

The goal is to demonstrate either the absence of tax loss or provide a clear explanation of the transactions.

3. Use Electronic Submission

Submitting documents through Dijital Vergi Dairesi helps to:

• formally record all submissions
• speed up the review process
• maintain a digital archive of all documentation.

Special Cases: Suspicious Documents (SMİYB)

If the tax administration identifies transactions involving fake or misleading documents, stricter rules apply.

Companies may need to:

• correct tax declarations
• provide explanations and supporting documentation.

For relatively small amounts, the izaha davet procedure may still apply. However, larger violations typically lead directly to a tax audit.

Why İzaha Davet Matters for International Businesses

For foreign investors and companies operating in Türkiye, this procedure plays an important role in tax risk management.

Key benefits include:

Risk mitigation
Potential disputes can be resolved before a formal audit begins.

Time management
The 30-day response period requires coordination between accountants and legal advisors.

Financial planning
Voluntary corrections can reduce the level of penalties.

Reputation protection
A well-prepared response can prevent lengthy tax investigations.

Conclusion

The İzaha Davet mechanism is an important element of Türkiye’s tax administration system. It allows companies to clarify potential tax issues before a formal audit begins and, if necessary, correct their tax reporting voluntarily.

For international entrepreneurs and investors, responding proactively and providing well-documented explanations can help minimize tax risks, protect business reputation, and maintain financial stability while operating in Türkiye.
