In the current economic, financial and social crisis that Europe is going through, and Portugal in particular, taxation is not only a competitive factor for companies, but also a determining factor for foreign investment. That's why it's increasingly important to know the tax policy in force in the country in which you're investing. Angola stands out in this context. The last decade has seen a strong expansion of Angolan capital, especially in Portugal, and many Portuguese companies have also been investing there. The Angolan economy is currently overly dependent on oil revenues. For this reason, Angola recently began a process of tax reform, the main objectives of which are to increase non-oil tax revenues, broaden the tax base, rationalise tax incentives, increase control through voluntary tax payments and combat tax fraud. This gave rise to the motivation to develop the theme of this work and the interest in learning about and publicising the Angolan tax system.
