Taxation Authority and Constitutional Limits

Entrance

For a state to survive, provide public services, and maintain social order, it is essential to generate revenue. The most important source of state revenue is taxes. Since taxation is a financial obligation that directly interferes with individuals' property rights and restricts their economic freedom, the limits of the power to tax are extremely important.

The Constitution of the Republic of Turkey defines both the basis and the limits of the state's power to tax. Within this constitutional framework, taxation is guaranteed by principles such as legality, equality, financial capacity, and proportionality

1. Legal Basis of Taxation Authority

a) The Concept of Taxation Authority

The power to tax refers to the state's right to collect taxes from citizens and other taxpayers to cover public expenditures. This power is a natural extension of sovereignty. However, this power is not unlimited; it is bounded by constitutional limits and general principles of law.

b) Article 73 of the Constitution

The primary source of the power to tax is Article 73 of the Constitution of the Republic of Turkey. The relevant provision is as follows:

“Everyone is obligated to pay taxes according to their financial capacity to cover public expenditures. Taxes, duties, fees, and similar financial obligations are imposed, amended, or abolished by law.”

Three fundamental principles emerge from this provision:

1. Everyone pays taxes (principle of generality).
2. Taxes are levied according to financial capacity (financial capacity principle).
3. Taxes can only be imposed, abolished, or amended by law (principle of legality).

2. Elements of Taxation Authority

The power to tax consists of various elements. These elements also form the basis of constitutional limits:

a) The Element of Legality

The power to levy taxes belongs solely to the legislative body . No administrative body or executive branch can levy taxes unilaterally. This is one of the fundamental guarantees of the rule of law.

b) Taxation According to Financial Capacity

Taxation should be proportionate to individuals' economic capacity. The phrase "according to financial capacity" in Article 73 of the Constitution is a fundamental criterion for tax justice. This principle prevents low-income citizens from being overwhelmed by excessive taxes.

c) Purpose of Covering Public Expenditures

Taxes are collected to enable the state to provide public services. Taxation cannot be used as an arbitrary or punitive tool.

3. Constitutional Limits of Taxation Authority

The power to tax is not unlimited. As a consequence of the rule of law principle, the state's power to tax is framed by various constitutional limits.

a) The Principle of Legality

• Taxes, duties, and fees can only be imposed by law.
• This principle the democratic legitimacy of taxes , because the authority to levy taxes belongs to the Grand National Assembly of Turkey, composed of representatives elected by the people.
• The principle of "legality of taxes" is also strongly emphasized in the decisions of the Supreme Court and the Constitutional Court.

b) The Principle of Equality

The principle of equality, guaranteed in Article 10 of the Constitution, also applies in the field of taxation. The tax burden should be distributed fairly among individuals without discrimination.

c) Principle of Financial Capacity

The principle of fiscal capacity, explicitly stipulated in Article 73 of the Constitution, is a cornerstone of tax justice. Taxes can be applied at different rates depending on the economic situation of individuals. For example, a tax system is a reflection of this principle.

d) The Principle of Proportionality

Taxation cannot disproportionately restrict an individual's property rights. Tax obligations must strike a fair balance between the public interest and individual rights.

e) Principle of Non-Retroactivity

Tax laws, as a rule, cannot be applied retroactively. Tax liability applies only to events that occurred after the date the law came into effect.

4. The Role of the Administration in the Exercise of Taxation Authority

While the power to levy taxes rests with the legislature, the administration also plays a significant role in the taxation process.

• The Ministry of Finance and the Revenue Administration enforce tax laws.
• Administrative regulations (notices, circulars, circulars) clarify the implementation.
• However, these regulations do not have the force of law; they are merely explanatory.

5. Judicial Review of Taxation Authority

Because taxation directly interferes with property rights, it is subject to judicial review.

• Tax courts and the Council of Stateresolve tax disputes.
• The Constitutional Courtcan annul laws that exceed their taxation authority or violate constitutional principles.
• In this way, taxpayers' rights are constitutionally guaranteed.

6. Taxation Authority and Fundamental Rights

Taxation directly affects individuals' property rights (Article 35 of the Constitution). Therefore, taxation cannot be applied arbitrarily. Furthermore, taxes have a restrictive effect on economic freedoms and freedom of enterprise. For this reason, the balance between taxation and fundamental rights is maintained within constitutional limits.

---

7. Cases of Exceeding the Limits of Taxation Authority

Exceeding the limits of the state's taxing authority usually occurs in the following situations:

• Collecting unlawful taxes or fees,
• Creating an unfair tax burden that is contrary to financial capacity,
• Treating someone in a way that violates the principle of equality,
• Excessive tax policies and extreme restrictions on property rights.

In these cases, taxpayers have the right to appeal to the courts.

Conclusion

The power to tax is one of the most fundamental sovereign powers of the state. However, since this power directly affects individuals' property rights and economic freedom, it is framed by constitutional limits.

Article 73 of the Constitution of the Republic of Turkey defines both the basis and limits of taxation. The principles of legality, equality, taxation according to financial capacity, proportionality, and non-retroactivity are fundamental constitutional guarantees that protect both taxpayer rights and the rule of law.

Therefore, the power to tax is not only a financial instrument but also a fundamental element of a democratic state governed by the rule of law. The delicate balance between meeting the state's financial needs and protecting the fundamental rights of individuals can only be achieved by adhering to constitutional limits.
