Portugal taxes residents on worldwide income (the former Non-Habitual Resident, NHR, regime closed to new applicants on 1 January 2024, with a transitional window to 31 March 2025 for those who met specific pre-closure conditions; it has been replaced by the Tax Incentive for Scientific Research and Innovation, IFICI, unofficially known as "NHR 2.0," offering a 20% flat rate on qualifying Portuguese-source employment/self-employment income for up to 10 years for new residents in specific qualifying sectors, with a narrower scope than the original NHR - existing NHR holders retain their original terms for the remainder of their 10-year period) and non-residents on Portugal-source income only. Portugal operates an administrative assessment system: the tax authority (Autoridade Tributaria) calculates and issues the final assessment (liquidacao) after the taxpayer's return is filed and reviewed.
The Portuguese tax year is the calendar year. The individual filing deadline typically falls in June of the following year, confirmed annually by the Portuguese tax administration (Autoridade Tributaria).
Portugal's headline corporate income tax (CIT) rate is 19%.
The headline personal income tax (PIT) rate is residents up to 48% (+2.5-5% solidarity surtax); non-residents 25% generally.
The standard VAT/GST (or equivalent consumption tax) rate is 23%.
An individual is a Portuguese tax resident if they spend more than 183 days in Portugal within any 12-month period beginning or ending in the tax year (days need not be consecutive), or if they maintain a place of abode available to them on December 31 that indicates an intention of habitual residence. Where residence is acquired via the 183-day test, it is deemed to begin on the first day of presence. Residents are taxed on worldwide income; non-residents only on Portugal-source income. Portugal also imposes an exit tax on unrealized capital gains for certain assets upon cessation of residency.
A non-Portuguese entity has a Portuguese permanent establishment through a fixed place of business or a dependent agent habitually concluding contracts in Portugal on the entity's behalf, following the OECD Model Treaty definition as applied under Portuguese domestic law and any applicable tax treaty.
Portugal's CFC regime (aligned with EU ATAD) attributes the profits of a non-resident entity to Portuguese-resident shareholders (individuals or companies) holding, directly or indirectly, at least 25% of the capital, voting rights, or income/asset rights (reduced to 10% if Portuguese residents collectively hold at least 50%) - including holdings via a legal representative, fiduciary, or intermediary. Attribution applies where the entity is resident in a blacklisted jurisdiction, or where its effective tax rate is below 50% of the tax that would apply under Portuguese rules (a related "not low-taxed" safe harbor requires an effective rate of at least 60% of the standard Portuguese CIT rate, i.e., roughly 12.6%). CFC treatment does not apply to entities resident in another EU or EEA state (with administrative cooperation) provided there are valid economic reasons for the entity's operations, supported by real staff, equipment, and premises. Distributed profits previously imputed under CFC rules are deductible on actual distribution to avoid double taxation.
Portugal has no formal debt-to-equity thin capitalization rule. Instead, net financing expenses are deductible up to the higher of EUR 4 million or 30% of tax-EBITDA, per Article 67 of the CIT Code (per PwC, current as of mid-2026); this EUR 4 million figure superseded an original EUR 1 million threshold set when Portugal first implemented the EU ATAD interest limitation rule in 2019, so older sources citing EUR 1 million reflect prior law rather than the current standing threshold. Unused deduction capacity where net interest falls below the 30% ceiling can be carried forward up to five years; groups filing under Portugal's group taxation regime may elect to apply the limitation on a group-consolidated basis.
Portugal does not use an elective check-the-box classification system; entity classification generally follows the entity's actual legal characteristics. Portugal has implemented ATAD2-aligned anti-hybrid rules denying deductions for payments producing a hybrid mismatch outcome.
No foreign bank account or foreign financial asset reporting regime exists in Portugal requiring residents to separately disclose foreign accounts; foreign income is reported through the standard annual tax return.
Portugal provides a participation exemption for qualifying dividends and capital gains: a Portuguese company holding at least 10% of a subsidiary's capital for a continuous minimum 12-month period is generally exempt from Portuguese corporate tax on dividends and capital gains from that shareholding, subject to a subject-to-tax condition on the subsidiary and anti-abuse provisions targeting purely passive or artificial holding structures.
Portugal has a real foreign tax credit regime for both individuals and companies for foreign tax paid on foreign-source income also taxed in Portugal, capped at the Portuguese tax otherwise due on that income, available under an applicable treaty or unilateral relief provisions.
Per Portugal's own tax authority (Autoridade Tributaria e Aduaneira), Portugal has signed 79 double tax conventions, of which 78 are in force and 1 remains signed but not yet in force. Named partners include the US, UK, Canada, South Africa, most major European economies, and the CPLP Portuguese-speaking nations (Brazil, Angola, Mozambique, and others). A new Portugal-UK treaty, signed September 15, 2025 and ratified by Portugal, entered into force December 29, 2025, taking effect January 1, 2026. Notably, Finland terminated its treaty with Portugal effective January 1, 2019, and Sweden terminated its treaty effective January 1, 2022 - neither has been replaced as of the most recent verification.
