Tax Convention

The interpretation and application of international tax laws are crucial for companies and individuals working across borders. The tax treaty plays an essential role in this context, alleviating tax implications for those who may be subject to double taxation. This article explores the nature and importance of tax treaties.

What is a tax treaty?

A tax treaty is a bilateral agreement between two countries aimed at ensuring that income earned abroad is not taxed in both the source country and the recipient’s country of residence. These agreements define the allocation of taxing rights between countries, specify rules for various categories of income and establish procedures to avoid double taxation problems. They also help prevent international tax evasion and fraud.

Key principles of tax treaties

Tax treaties are based on a number of fundamental principles, guaranteeing fairness and predictability for taxpayers and the tax authorities concerned.

Tax credits and exemptions

To mitigate double taxation, the country of residence can either grant a credit for tax paid abroad, or exempt the income completely from national taxation. The approach adopted varies according to the conventions and revenues in question. Find out more about this topic by exploring tax credits.

Exchange of information

The exchange of information between tax authorities is a cornerstone of tax treaties, enabling better control and increased cooperation in the fight against tax fraud. This helps countries to apply their respective domestic tax laws effectively.


The principle of non-discrimination prohibits a country from treating the taxpayers of another country less favorably than its own residents in similar circumstances. This is fundamental to ensuring fair competition.

The benefits of tax treaties

By regulating international income and wealth tax, tax treaties offer numerous advantages for both countries and taxpayers.

For companies

Companies benefit directly from the reduction in double taxation, which eases their tax burden and encourages trade and investment between signatory countries. For example, a tax lawyer can advise a company on how to optimize its tax obligations under a tax treaty.

For individuals

Individuals who receive income from abroad, such as pensions or rental income, can also have their taxation simplified and reduced thanks to tax treaties.

For tax authorities

The agreements reduce tax conflicts between states and streamline administrative procedures, generating greater efficiency for tax authorities.

Frequently asked questions

Here is a list of frequently asked questions about tax treaties.

What is the difference between a tax treaty and a tax convention?

Do all tax treaties follow the same rules?

No, although they are often based on OECD or UN models, conventions vary according to the specific relationships and negotiations between the signatory countries.

How do you know whether a tax treaty applies to a given situation?

It is advisable to consult a tax litigator or an international tax expert to determine the application of a tax treaty to specific cases.

Can tax treaties be amended or cancelled?

Yes, they can be renegotiated, modified or cancelled if the signatory countries so agree. Global tax changes may require updates to existing agreements.
