International Tax

Mexico has one of the most developed international tax systems in Latin America. The increasing flow of investment, foreign trade and foreign residency has driven this tax sophistication. Understanding international tax obligations is essential for both companies and individuals.

Major Taxes

The main taxes that apply to foreign sources are:

  • Income Tax (ISR) on foreign-source income.
  • Value Added Tax (VAT) on imports and services provided by non-residents.
  • Flat Rate Business Tax (IETU) on income obtained in Mexico by foreigners without a permanent establishment.


Taxes on dividends, interest, capital gains, royalties, technical assistance and other cross-border payments.Mexico has entered into more than 60 bilateral tax treaties regulating tax rates, double taxation and other special provisions with trading partners.

Tax Residency

Tax residency determines in which country an individual must pay taxes. In Mexico, residency is based on length of stay and family ties. Resident foreigners are taxed on their global income, while non-residents are only taxed on their local income.

Double Taxation Agreements

Mexico has agreements with many countries to avoid double taxation. These agreements specify how income and assets will be taxed, offering some protection to foreign investors.

Tax Obligations

Foreigners who own property in Mexico face tax obligations, such as the payment of income and capital gains taxes. It is essential to comply with these requirements to avoid penalties.

Tax Planning

International tax planning allows foreigners to structure their assets efficiently to minimize the tax burden. This may include the use of trusts and other legal strategies.

Withholding at Source

Foreigners working in Mexico may be subject to withholding taxes. Understanding these rules is essential to avoid surprises on your tax return.

Legal Advice

Since tax laws can be complicated, it is advisable to seek specialized legal and accounting advice to ensure compliance and take advantage of legal tax opportunities.
