Portuguese tax law & double taxation treaties.
We analyse the Portuguese taxation of income and assets with cross-border elements, apply double-taxation treaties where relevant and assess the Portuguese foreign-tax credit. The result depends on the type of income, the source state and evidence of tax effectively paid.
Overview
Portuguese tax and international tax planning.
International individuals and businesses face complex tax obligations across multiple jurisdictions. Our tax team helps you navigate Portuguese taxation, apply treaty benefits and coordinate your cross-border position.
Portuguese tax law
Deep knowledge of Portuguese income tax, corporate tax and property tax rules.
Treaty application
Application of tax treaties and the Portuguese foreign-tax-credit rules according to the type of income, the source state and the available documentation.
International reporting
FATCA and CRS impose reporting duties primarily on financial institutions. Anti-money-laundering legislation imposes duties on obliged entities, including lawyers in the situations defined by law. These regimes are not, by themselves, personal tax-return services. Where a matter involves obligations in another country, we coordinate with tax advisers qualified in that jurisdiction.
