Event at Martins Castro headquarters clarifies tax issues in Portugal

Last week, the Martins Castro held an exclusive event at its headquarters in partnership with the Young Business Club – YBC focusing on the Portuguese tax system and international tax strategies. The meeting featured lectures by Thiago Huver, Partner and COO, and Teresa Morais Correia, from the Martins Castro legal team, who addressed crucial topics for investors and residents in Portugal.
Main topics covered
- Portuguese Tax System: Tax residency is defined by physical presence (more than 183 days per year), permanent domicile or economic connections, and not by nationality. Rules for companies, such as the place of incorporation or central management, were also highlighted.
- End of the Non-Habitual Resident Regime (NHR): With the program ending in 2023, a transition period for 2024/2025 was introduced, which benefits employment contracts and acquisitions of already established properties. Future tax incentives include a fixed rate of 20% for 10 years for residents working in scientific research, startups or higher education.
- Corporate Tax Planning: Investment strategies in real estate funds and renewable energy projects were discussed, with emphasis on reductions of up to 28% in taxes for non-residents.
Incentives and international treaties
The speakers also highlighted the 70 international treaties of Portugal to avoid double taxation, tax credits for foreign income and incentives for scientific innovation.
