Tax Law

What Is Tax Law?

Tax law is the field of law that regulates tax-related relationships between the state and taxpayers, tax obligations, the actions of the tax administration and disputes arising from these actions. This field covers the processes of the emergence of tax, assessment, accrual, collection, application of tax penalties and filing lawsuits before tax courts.

Tax law is not limited only to the payment of tax debts. Tax inspections, special irregularity penalties, tax loss penalties, payment orders, attachment procedures, precautionary attachment, settlement applications, correction requests and lawsuits filed before tax courts are also evaluated within the scope of tax law.

Scope of Tax Law

Tax law is a technical field of public law that regulates the relationship between the administration and the taxpayer. Whether the actions established by the tax administration comply with the law is examined together with the taxpayer’s bookkeeping and documentation order, declaration obligations, commercial records and procedural compliance in the taxation process.

The main matters most frequently encountered within the scope of tax law are as follows:

  • Income tax disputes

  • Corporate tax disputes

  • Value added tax disputes

  • Special consumption tax disputes

  • Stamp tax disputes

  • Property tax disputes

  • Inheritance and transfer tax disputes

  • Tax penalties and payment orders

  • Tax inspections and assessment procedures

Each type of tax has different tax base, rate, exemption, exception and declaration principles. Therefore, every dispute evaluated within the scope of tax law is examined separately according to the type and basis of the action, the notification date and the taxpayer’s commercial records.

Principles of Taxation

Tax law is based on the conduct of taxation procedures in accordance with the principles of legality, equality, ability to pay, legal certainty and clarity. The tax administration must have a legal basis when establishing actions, and the taxpayer must be able to foresee their rights and obligations.

In the taxation process, it is important that the tax base is determined correctly, the taxable event is identified in accordance with procedure and, where a penalty is to be imposed, fault and unlawfulness are demonstrated concretely. Therefore, in tax law files, not only the tax debt but also the basis of the action, procedure, notification date, report content and evidence are evaluated in detail.

Tax Lawsuits

Tax lawsuits are filed when the taxpayer applies to the judiciary against actions established by the tax administration. The purpose of these lawsuits is to annul the assessment, penalty, payment order, precautionary attachment or administrative action alleged to be unlawful.

In tax lawsuits, the time limit for filing a lawsuit is determined according to the type of action and the notification date. Since missing the time limit may cause loss of rights, the notification date, type of action, available remedy and lawsuit period must be carefully evaluated before filing a lawsuit.

In lawsuits filed within the scope of tax law, the content of the petition, submission of evidence, evaluation of commercial records and legal reasoning directly affect the outcome of the process.

Tax Penalties and Tax Inspections

Tax inspections are carried out to determine whether the taxpayer’s declarations, books, documents and commercial records comply with legislation. As a result of the inspection, tax loss penalties, irregularity penalties, special irregularity penalties or additional assessments may arise.

When evaluating the legality of tax penalties, only the amount of the penalty is not taken as the basis. The act on which the penalty is based, the tax inspection report, tax technique report, books and document records, electronic declarations, invoice system, notification process and the taxpayer’s defenses are examined together.

The following matters are particularly important in this process:

  • Conducting the inspection in accordance with procedure

  • The tax inspection report being based on concrete findings

  • Protection of the taxpayer’s right of defense

  • Clearly demonstrating the act on which the penalty is based

  • Evaluating the connection between tax loss and the taxpayer’s conduct

  • Operating notification procedures and time limits in compliance with the law

In terms of tax law, not only the consequence of the penalty but also the actions and evidence on which the penalty is based are determinative.

Evidence and Burden of Proof in Tax Disputes

Evidence and burden of proof constitute the foundation of tax disputes. The taxpayer’s commercial books, invoices, bank records, contracts, delivery notes, electronic documents and accounting records play a decisive role in the lawsuit.

The legality of findings made by the tax administration is also examined separately. In cases of incomplete inspection, assessments based on assumptions, reports prepared contrary to procedure or violation of the taxpayer’s right of defense, annulment of the action may arise within the scope of tax law.

Therefore, in tax disputes, evidence must be collected on time, commercial records must be analyzed correctly and the administration’s findings must be legally reviewed.

Settlement, Objection and Administrative Application Remedies

In tax disputes, administrative application remedies are evaluated before applying to litigation or in connection with the litigation process. Settlement, correction and complaint applications, repentance provisions, invitation to explanation processes and penalty reduction requests may arise depending on the nature of the dispute.

Each of these application remedies has different time limits, conditions and legal consequences. Therefore, before making an application, the type of action, nature of the penalty, commercial position of the taxpayer, available evidence and its effect on the lawsuit filing period must be evaluated together.

Within the scope of tax law, choosing the wrong application remedy or missing the time limit may cause loss of rights for the taxpayer. Therefore, it is important to plan the administrative application process together with the litigation strategy.
