Straight answers.
Yes. Since 2023, short-term crypto gains (assets held under 365 days) are generally taxed at a flat 28%, while gains on assets held longer are usually exempt for non-professional investors. Trading as a business, or receiving crypto as income, is taxed differently. The exact treatment depends on the facts, which is what a position report establishes.
Since 1 January 2026, EU crypto-asset service providers collect and report their users’ transaction data to national tax authorities, with the first exchanges of information due by September 2027. The Exposure Report reconstructs what that record will show about you, before it arrives on a tax inspector’s desk.
IFICI is Portugal's tax incentive for scientific research and innovation, which replaced the NHR regime for new arrivals from 2024. It offers a 20% flat rate on qualifying Portuguese employment and self-employment income and exemptions on most foreign income, for up to ten years. It is aimed at people in qualifying R&D, higher-education, startup and certain high-value roles who become Portuguese tax resident and have not been resident in the previous five years.
