Legal Issues Arising in VAT Applications: The Delicate Balance of Tax Justice

1) Introduction: The Complex Structure of VAT and the Inevitability of Legal Disputes

Value Added Tax (VAT) of indirect taxes and requires intensive auditing and declaration processes for both taxpayers and the administration.
However, the very nature of this system, documentation, record-keeping, and chain transactions, is also the source of numerous legal disputes.

Value Added Tax (VAT) is a tax levied at every stage of the purchase of goods or services, but the ultimate recipient is the consumer. Because of this characteristic, both the deduction and refund of VAT are subject to strict procedures. It is precisely at this point that conflicts arise in practice between the administration's broad interpretations and taxpayer rights

This article will examine common legal issues in VAT applications, refunds, deduction refusals, detection of forged documents, application of special procedures, and judicial review .

2) Legal Basis and Fundamental Principles of VAT

2.1. Legal Basis

The main articles of the Value Added Tax Law (Law No. 3065) are as follows:

• Article 1: Defines the subject of the tax (supply of goods and provision of services).

• Articles 29–34: Regulate the provisions for tax reductions.

• Article 32: Defines the right of return.

• Articles 54–55: These articles contain the administration's powers of investigation, guarantee, and application of special principles.

2.2. Fundamental Principles

• Principle of Legality: Taxes can only be imposed, amended, and abolished by law (Constitution Article 73).

• Certainty and Predictability: Taxpayers should know their tax obligations in advance.

• Equality and Proportionality: VAT regulations should not produce different results among taxpayers in the same situation.

3) The Most Common Legal Problems Encountered in VAT Applications

3.1. Delays and Rejections in VAT Refund Claims

One of the most controversial aspects of the VAT system is the refund process.
Taxpayers who export, participate in investment incentive-based transactions, or use reduced VAT rates can reclaim their carried-over VAT through a refund request.

But in practice:

• The review and reporting process can take months,

• The administration can arbitrarily demand "security"

• Refund requests may be rejected due to procedural deficiencies.

This situation disrupts the taxpayer's cash flow and severely impacts their working capital.

Legal Issue: Delaying the restitution request constitutes a disproportionate interference with the right to property (Article 1 of Protocol No. 1 to the ECHR). The administration's extension of the deadline on the grounds that "the review is not complete" is contrary to the rule of law principle in the Constitution .

3.2. Rejection of VAT Reduction

Tax authorities sometimes deny taxpayers their right to a VAT deduction due to problems with their purchase invoices.
The main reasons for this refusal are:

• Allegations of using forged documents or documents with misleading content,

• Another company in the supply chain may have forged documents,

• The belief that the goods or services have not been actually delivered.

Legal Issue: A taxpayer's right to deduct VAT can only be restricted to transactions that were carried out through their own fault or with their knowledge . The fault of another company in the supply chain cannot be attributed to the taxpayer.

The opposite approach is incompatible with the presumption of innocence and the principle of proportionality . The European Court of Justice (ECJ) has adopted a similar approach in its case law on this matter (for example, the Mahagében and Dávid judgments ).

3.3. Practices of Forgery (FMO)

If the tax authorities detect forged documents (SMİYB), they may place the taxpayer on the "special procedures list".
This situation means that the taxpayer:

• It prevents them from receiving a VAT refund

• It makes it impossible to conduct transactions without bank collateral

• This leads to the tax authorities classifying the taxpayer as a "risky taxpayer".

Legal Issue: The process of placing a taxpayer under special regulations is often carried out unilaterally and without a court decision . This means that the administration uses its "administrative discretion" in a punitive manner . However, objective punishment cannot be applied unless the taxpayer has forged documents through their own actions .

Such proceedings should be subject to judicial review; otherwise, the principle of individual responsibility for crime and punishment would be violated.

3.4. Dependence of Discounts on Documents and Problems in Electronic Applications

In the VAT system, the most important proof is invoices and accounting records.
However, with the introduction of e-invoice, e-ledger, and e-archive systems, new types of disputes have emerged:

• The invoice is not showing up in the system due to a technical issue

• The e-invoice was not approved on time

• The document was deemed invalid due to an XML or digital seal error.

Since these technical malfunctions occurred outside the taxpayer's control, tax penalties or denying tax deductions would be unfair.

Legal Opinion:
Situations arising from electronic system errors a service defect on the part of the administration ; therefore, the taxpayer cannot be penalized.

---

3.5. VAT Withholding and Confusion of Responsibility

Although the withholding tax system was introduced to increase tax security, it causes serious confusion in practice,
especially in partial withholding tax applications

• Failure to make the required deduction by the buyer,

• The incorrect application of the withholding tax rate between the parties,

• declaring withholding tax to the wrong company
  can result in penalties for taxpayers.

Legal Issue:
The withholding tax system has complicated the taxpayer's obligations.
The administration should not punish well-intentioned errors, but should look for elements of intent or negligence in determining "tax loss."

4) Judicial Review in VAT Refund and Audit Procedures

Judicial review is the last resort for taxpayers in VAT refund and deduction disputes. Tax courts examine arbitrary actions of the administration within the framework of the principles of "proportionality," "rule of law," and "property rights."

4.1. Scope of Judicial Review

Courts consider the following criteria:

• Does the administration's decision have a legal basis?

• Is there justification and evidence for the action?

• Has the taxpayer been granted the right to defend themselves?

• Is the penalty or refusal of return proportionate?

4.2. Trends in Court Practice

Tax courts are developing precedents in favor of taxpayers , particularly in VAT refund cases. Delays or arbitrary demands for security deposits by the administration are considered an interference with property rights.

Furthermore, in cases involving special procedures, there has been an increase in cancellation decisions in recent years due to the lack of concrete proof of the taxpayer's fault.

5) Suggestions for Preventing Legal Problems in the VAT System

1. Digital Transparency in Refund Processes:
   It should be made mandatory for VAT refund applications to be tracked on a digital platform and for the administration to explain the reasons for delays to the taxpayer.

2. Fault-Based Responsibility Instead of Objective Liability:
   In cases of tax deduction rejection and penalty imposition, the taxpayer's fault should be sought; liability should not be imposed for actions arising from third parties in the supply chain.

3. Abolition of Special Provisions or Subjection to Judicial Review:
   The inclusion of taxpayers on "risky" lists should only be possible through a court decision.

4. Amnesty System for E-Invoice Errors:
   A "correction period" should be granted for e-invoice or e-ledger errors that occur due to technical reasons.

5. Time Limit in Tax Audits:
   The refund or audit period should not exceed 6 months; otherwise, it will be considered an implicit acceptance in favor of the taxpayer.

6) Conclusion: Legal Guarantee in VAT is the Foundation of the Tax System

The Value Added Tax (VAT) system is the backbone of modern tax administration. However, the reliability of this system the predictability of the law, not on arbitrary administrative practices .

Therefore, a lasting solution in tax law is...

• Transparent administrative practices,

• Fault-based punishment system,

• effective judicial review
  .

Tax justice is ensured not only by collecting taxes, but also by refunding wrongly collected taxes and through proportionate audits .
