Business income taxation in Portugal: a brief analysis of the simplified regimes

Abstract

The taxation regime for corporate income in Portugal is not truly unitary. These revenues can be taxed under the Personal Income Tax or Corporate Income Tax. Additionally, in each case, the taxable income can be determined basing either on the general regime rules or on the simplified regime ones. This coexistence of legal regimes poses – or may pose – questions of compatibility with the Portuguese constitutional norms, especially with Article 104.
