This article provides a brief overview of the Portuguese tax system, as far as corporate income tax and tax benefits are concerned, and refers to the latest developments implemented by the 2007 State Budget Law and the local finance law, which came into force in January.

Portugal has a modern and increasingly sophisticated tax system. Over the past few years, far-reaching reforms have taken place which have resulted in fairer and more competitive taxes. The current income taxation system is a result of the 1988 reform, in force since 1 January, 1989.
