IFICI Deadline: Miss It and You Could Lose Years of Tax Benefits
Individuals who became Portuguese tax residents in 2026 must apply for the IFICI (Tax Incentive for Scientific Research and Innovation) by December 31st. Failing to apply by this deadline means losing years of potential tax benefits, as the 10-year incentive period is not extended to compensate for delayed applications. Eligibility requires meeting specific professional and residency criteria within the year of becoming a tax resident, and failing to meet those conditions in 2026 cannot be recovered in later years.
Why it mattersIf you became a tax resident of Portugal in 2026, you must assess your eligibility and submit your IFICI application by December 31st to avoid permanently losing years of potential tax savings.
