The balance found between capital gains and losses derived from the disposal of corporate rights and other marketable securities realised in the same year, as determined according to the corporate income tax code (excepting gains derived from the disposal of shares held at least for twelve months), earned by individual investors must be reported and is subject to a 10% corporate income tax rate.
An option for aggregating/including the gains received in the individual's investor total taxable income is also available.
Capital gains arising from the disposal of shares are subject to the standard corporate income tax rate of 25% plus municipal surcharge (up to a maximum of 2.5%), resulting in an aggregate corporate income tax rate of 27.5%.
Notwithstanding the above, capital gains arising from the disposal of shares, other securities, autonomous warrants issued by residents and financial derivatives issued in a regulated stock market, are exempt if earned by non-resident entities without a permanent establishment in Portugal, unless:
> the non-resident entity without a permanent establishment in Portuguese territory is owned by resident entities in more than 25% directly or indirectly;
> the non-resident beneficiary of the income is resident in a territory that is a listed tax haven;
capital gains relate to shares or interest in companies resident in Portugal if more than 50% of the company's assets consist of Portuguese real estate or relate to shares in a Portuguese holding company that controls such a Portuguese property company.
Companies or individuals resident in a country with which Portugal has signed a DTC may benefit from non taxation in Portugal of the above referred to capital gains depending on the provisions specifically agreed under the terms of the DTC.
