Portugal Tax Regime

Portugal taxes resident companies on worldwide income at a standard corporate income tax (IRC) rate of 19% on the mainland, reduced to 13.3% in the autonomous regions of Madeira and the Azores, with a 15% rate on the first EUR 50,000 of profit for small and medium-sized companies. A municipal surtax (up to 1.5%) and a progressive state surtax (3%–9% on profits above EUR 1.5 million) lift the combined rate on large profits to roughly 29.5%. A full participation exemption on qualifying dividends and gains, a patent box, the generous SIFIDE research-and-development credit, the Madeira International Business Centre and an extensive treaty network make Portugal a competitive EU holding and operating location.

Individuals are taxed under the personal income tax (IRS) on a progressive scale to 48% plus a solidarity surcharge, with investment income generally taxed at a flat 28%, and a new inbound regime (IFICI) for qualifying scientific, research and innovation talent. A company is resident if its head office or place of effective management is in Portugal.

1.1 Sources of law and treaties

The Corporate Income Tax Code (IRC), the Personal Income Tax Code (IRS), the VAT Code and the Tax Benefits Statute, together with the annual State Budget Law, govern the system, administered by the Tax and Customs Authority (Autoridade Tributária e Aduaneira). EU directives, an extensive treaty network and the OECD multilateral instrument apply, and binding-information rulings and an arbitration court (CAAD) support the system.

1.2 Recent developments

The most consequential recent and pending changes are:

A reduction of the standard mainland corporate income tax rate to 19% (from 21%), with the SME first-bracket rate at 15%, as part of a multi-year programme of corporate-rate cuts.

Implementation of the OECD Pillar Two regime (the Global Minimum Tax Regime, RIMG) — an income inclusion rule and a qualified domestic minimum top-up tax (fiscal years from 1 January 2024) and an undertaxed-profits rule (from 1 January 2025) — for groups with consolidated revenue of at least EUR 750 million, with first filings due in 2026.

The IFICI regime (the ‘tax incentive for scientific research and innovation’), which replaced the former non-habitual-resident regime for new registrants from 2024, granting a 20% flat rate on qualifying Portuguese employment and self-employment income.

2.1 Residence and scope

A company is resident — and taxed on worldwide income — if its head office or effective management is in Portugal; non-residents are taxed on Portugal-source income and on the income of a Portuguese permanent establishment. A resident company may elect to exclude the profits and losses of a foreign permanent establishment (subject to a minimum-taxation condition and exclusion of blacklisted jurisdictions), a territorial-style option for outbound operations.

2.2 Rates and surtaxes

The standard IRC rate is 19% on the mainland (13.3% in Madeira and the Azores). Small and medium-sized companies pay 15% on the first EUR 50,000 of taxable income (10.5% in the autonomous regions), with further reductions for companies in inland territories. On top of IRC, a municipal surtax (Derrama) of up to 1.5% of taxable profit applies in many municipalities, and a progressive state surtax (Derrama Estadual) applies at 3% on profit between EUR 1.5 million and EUR 7.5 million, 5% to EUR 35 million and 9% above — so the combined marginal rate on the largest profits reaches about 29.5%.

2.3 Participation exemption

Portugal's participation exemption fully exempts qualifying dividends and capital gains on shares where the company holds at least 10% of the capital or voting rights for at least one year, the subsidiary is subject to (and not exempt from) a qualifying income tax, and it is not resident in a blacklisted jurisdiction. The exemption applies equally to inbound dividends and to gains on disposal, underpinning Portuguese holding structures and complementing the optional foreign-PE exemption.

2.4 Patent box

Net income from the licensing or transfer of qualifying intellectual property — patents and industrial designs or models — benefits from an 85% deduction under the OECD modified-nexus approach, reducing the effective rate on qualifying IP income to roughly 15% of the headline rate. The regime rewards IP developed through the taxpayer's own qualifying R&D expenditure.

2.5 Income determination and autonomous taxation

Taxable profit follows the statutory accounts adjusted for tax, with depreciation at official rates and specific limits on provisions and certain costs. A distinctive feature is ‘autonomous taxation’ — a separate self-assessed charge, payable even where no IRC is due, on defined expenses such as representation costs (10%), car expenses (graduated by cost and vehicle type), undocumented expenses (50%) and payments to blacklisted jurisdictions (35%–55%), with the rates increased where the company is loss-making.

2.6 Interest limitation

Net financing expense is deductible only up to the higher of EUR 1 million or 30% of tax-EBITDA, with carryforward of disallowed interest (five years) and unused capacity (five years), implementing the EU anti-tax-avoidance directive. The rule applies alongside transfer-pricing scrutiny of related-party financing.

2.7 Losses

Tax losses may be carried forward without a time limit (following a recent change removing the former limited carryforward period), but their use is capped at 65% of the taxable profit of the year; there is no carryback. Anti-abuse rules can restrict loss use following a substantial change of ownership and activity, subject to exceptions and rulings.

2.8 Tax consolidation

A Portuguese group can elect the special group-taxation regime (RETGS) where the parent holds at least 75% of its subsidiaries (representing more than 50% of voting rights): the group is taxed on the aggregate of members' results, allowing immediate offset of profits and losses. Entry, exit and loss-utilisation rules apply, and the regime covers IRC (the surtaxes follow their own rules).

2.9 Controlled foreign companies and transfer pricing

The CFC rules attribute to a Portuguese controlling shareholder the undistributed profits of a low-taxed foreign entity (broadly where the foreign tax is below 50% of the Portuguese tax that would apply), subject to a genuine-economic-activity exclusion within the EU/EEA. Transfer pricing applies the arm's-length standard and the OECD Guidelines, with master-file, local-file and country-by-country documentation for larger groups; advance pricing agreements are available.

2.10 Incentives

Portugal's incentive landscape is among the EU's more generous: the SIFIDE II research-and-development tax credit gives a base credit of about 32.5% of qualifying R&D expenditure plus an incremental credit of 50% of the increase over the prior two years' average (within caps); the RFAI provides a tax credit and other reliefs for productive investment; and the Madeira International Business Centre offers a 5% corporate rate to licensed entities meeting substance and job conditions. A contractual-investment regime supports large projects.

2.11 Pillar Two

Portugal transposed the EU minimum-tax directive as the Global Minimum Tax Regime (RIMG): an income inclusion rule and a qualified domestic minimum top-up tax (fiscal years from 1 January 2024) and an undertaxed-profits rule (from 1 January 2025), for groups with consolidated revenue of at least EUR 750 million, with transitional country-by-country and other safe harbours. Filing obligations for fiscal year 2024 fall due in 2026.

3.1 Residence and rates

An individual is resident if present in Portugal for more than 183 days in a 12-month period or maintaining a habitual residence there, and residents are taxed on worldwide income. The IRS is progressive across nine brackets to a top marginal rate of 48%, plus an additional solidarity surcharge of 2.5% on income between EUR 80,000 and EUR 250,000 and 5% above EUR 250,000. Employment and pension income is aggregated, while certain categories (notably investment income) can be taxed separately.

Indicative; brackets are set annually. As-of June 2026.

3.2 Investment income and capital gains

Dividends, interest and capital gains on securities are generally taxed at a flat 28% (with an option to aggregate with other income at the progressive rates), and capital gains on real estate are taxed at the progressive rates on (for residents) 50% of the gain, with reliefs for the reinvestment of main-residence proceeds. A higher 35% rate applies to income paid to or from blacklisted jurisdictions.

3.3 The IFICI inbound regime

The IFICI regime (tax incentive for scientific research and innovation), which replaced the former non-habitual-resident regime for new arrivals from 2024, grants qualifying inbound individuals — broadly those taking up highly qualified employment in research, innovation, qualifying companies or certain professions — a 20% flat rate on their Portuguese-source qualifying employment and self-employment income, and an exemption for most categories of foreign-source income, for up to ten years. It is a significant draw for mobile skilled talent.

3.4 Succession, property and the absence of inheritance tax

Portugal levies no inheritance or gift tax as such; instead, gratuitous transfers attract stamp duty at 10% (with transfers to spouses, descendants and ascendants exempt). There is no recurrent net wealth tax, but an additional municipal property tax (AIMI) applies to high-value real-estate holdings on top of the annual municipal property tax (IMI), and property purchases bear the property-transfer tax (IMT).

Dividends, interest and royalties paid to non-residents are generally subject to 25% withholding (28% for payments to individuals), reduced or eliminated by treaty and by the EU Parent-Subsidiary and Interest-and-Royalties Directives; a punitive 35% rate applies to payments to blacklisted jurisdictions. Representative outcomes:

5.1 Anti-deferral, pricing and financing

The CFC rules (Section 2.9), transfer-pricing rules (Section 2.9) and interest-limitation rule (Section 2.6) form the core of Portugal's outbound and inbound framework, attributing low-taxed foreign profits, requiring arm's-length pricing and capping financing deductions. Anti-hybrid rules neutralise deduction/non-inclusion and double-deduction mismatches in line with the EU directives, and special charges apply to dealings with blacklisted jurisdictions.

5.2 General anti-avoidance, exit tax and disclosure

A general anti-abuse rule allows the tax authority to disregard arrangements that are essentially artificial and aimed at obtaining a tax advantage contrary to the law's purpose, supported by specific anti-avoidance provisions. An exit tax charges latent gains when a company transfers its residence or a PE's assets abroad (with EU deferral options), and mandatory-disclosure (DAC6) rules require reporting of certain cross-border arrangements.

5.3 Foreign tax relief

Double taxation is relieved by the participation exemption for qualifying dividends and gains and the optional foreign-PE exemption and, otherwise, by a credit for foreign tax limited to the Portuguese tax on the foreign income. Treaties allocate taxing rights and provide a mutual-agreement procedure, and Portugal's CAAD arbitration court offers an efficient dispute route.

6.1 Value-added tax

VAT (imposto sobre o valor acrescentado, IVA) is charged on the mainland at a standard rate of 23%, with reduced rates of 13% and 6% for specified goods and services, and lower rates in Madeira (22%/12%/5%) and the Azores (16%/9%/4%). Financial, insurance, medical and education services are exempt. Businesses register, charge and recover VAT, and the EU cross-border, reverse-charge and one-stop-shop rules apply; Portugal also operates extensive e-invoicing and SAF-T reporting obligations.

6.2 Property and stamp taxes

The annual municipal property tax (IMI) is levied on the rateable value of real estate (broadly 0.3%–0.45% for urban property), with an additional municipal property tax (AIMI) on high-value holdings. Property purchases bear the municipal property-transfer tax (IMT) at progressive rates. Stamp duty applies to a range of acts, contracts and documents (and to gratuitous transfers in place of an inheritance tax).

6.3 Social security and other

Employer and employee social-security contributions fund pensions and welfare and are a significant cost of employment. Excise duties (on fuel, alcohol, tobacco and vehicles), a banking-sector contribution and various environmental levies apply. There is no general net wealth tax and no inheritance tax (gratuitous transfers being within stamp duty).

7.1 Self-assessment and payment

Tax is administered by the Tax and Customs Authority under self-assessment. Companies file the annual IRC return (Modelo 22) by 31 May of the following year and an annual accounting-and-tax information return (IES) by mid-July, and pay IRC through three payments on account during the year plus a final settlement. Individuals file the IRS return between April and June, and VAT is filed monthly or quarterly with extensive SAF-T and e-invoicing data.

7.2 Rulings, audit and limitation

The general statute of limitation is four years (extended in defined circumstances). The authority conducts desk and field inspections, and binding-information rulings give certainty on the tax treatment of transactions. Late-payment and compensatory interest and penalties apply, mitigated by voluntary regularisation.

7.3 Disputes

A taxpayer may contest an assessment by administrative complaint and hierarchical appeal, by judicial challenge before the administrative and tax courts, or — distinctively — by arbitration before the Tax Arbitration Court (CAAD), a fast and widely used route. The mutual-agreement procedure and EU dispute-resolution mechanisms address cross-border double taxation.

Indicative deadlines. As-of June 2026.

9.1 Entity choice and regions

Business is conducted through an S.A. or the flexible Lda. (limited-liability company), or a branch taxed on its Portuguese establishment. The autonomous regions of Madeira and the Azores apply lower rates (a 13.3% standard rate), and the Madeira International Business Centre offers a 5% corporate rate to licensed, substantive entities; the optional foreign-permanent-establishment exemption gives outbound operations a territorial-style result.

9.2 Holding and financing structures

A Portuguese holding company combines the participation exemption on dividends and gains, the patent box and the treaty network, while financing is capped by the 30%-of-EBITDA / EUR 1 million interest rule. Autonomous taxation on company cars, representation costs and undocumented or blacklisted-jurisdiction payments is a distinctive recurring cost that planning must anticipate, increasing where the company is loss-making.

9.3 A worked illustration

A mainland company with EUR 10 million of profit pays corporate tax at 19% (EUR 1.9 million), the municipal surtax of up to 1.5%, and the state surtax (3% on profit between EUR 1.5 and 7.5 million, 5% to EUR 35 million and 9% above), giving a combined effective rate near 23–24% that rises toward 29.5% as profits grow. The SIFIDE research credit and the 85% patent box reduce this for qualifying research and IP activity.

9.4 Compliance and incentives

Portugal operates extensive SAF-T and e-invoicing reporting, files the corporate return (Modelo 22) by 31 May, and offers the fast CAAD arbitration route for disputes. The IFICI inbound-talent regime (a 20% flat rate) replaced the non-habitual-resident regime for new arrivals, and large groups face the Global Minimum Tax Regime with first filings due in 2026.
