Portugal introduces legislation for the transaction of crypto assets.
From January 1st 2023, Portuguese residents will have legal certainty pertaining to tax treatment of their investments in crypto assets. The 2023 Portuguese budget law stipulates that - amongst other things - capital gains from holdings in crypto which have been held for more than one year will be exempt from tax. Furthermore, income received in the form of crypto assets for the validation of new blocks in the blockchain (such as mining and staking ) will be taxable although taxation will be deferred until said assets are disposed of for fiat currency, goods or services. Lastly, disposals of one crypto asset for another will not be taxable under Portuguese law.
