Under Portuguese tax law, taxpayers no longer resident in Portugal are subject to immediate taxation in case of exchange of shares. Taxpayers are also taxed immediately in case of transfer to a company located abroad of assets and liabilities related to the exercise of an economic or professional activity. The Commission considers that such immediate taxation penalises those persons who decide to leave Portugal or transfer assets abroad, by introducing less favourable treatment for them in comparison to those who remain in the country or transfer assets to a resident company.
