IFICI (Tax Incentive for Scientific Research and Innovation) is the regime that replaced Portugal's NHR in 2024. It provides a special 20% IRS rate on net qualifying employment and self-employment income for 10 consecutive years to individuals who become Portuguese tax residents — provided they were not Portuguese residents in any of the previous 5 years and they carry out one of the activities in Article 58-A EBF, registered with the competent body (FCT, AICEP, AT, IAPMEI, ANI, Startup Portugal or the Autonomous Regions).

What IFICI Is

IFICI — short for Incentivo Fiscal à Investigação Científica e Inovação (Tax Incentive for Scientific Research and Innovation) — is a special IRS taxation regime for new Portuguese tax residents who engage in activities of significant economic and social value.

It was established by Article 263 of Law no. 82/2023 of 29 December (Portugal's 2024 Budget Law), which added Article 58-A to the Tax Benefits Statute (EBF — Estatuto dos Benefícios Fiscais). The same instrument simultaneously revoked the Non-Habitual Resident (NHR) regime, effective 1 January 2024 — though a transitional rule covers those who became residents by 31 December 2024 and held one of the items listed in Article 236(3) of Law 82/2023 (for example, an employment contract signed by 31 December 2023 or a lease signed by 10 October 2023).

Operational rules were issued via Ordinance no. 352/2024/1 of 23 December, amended by Ordinance no. 52-A/2025/1 of 25 February. The registration model was approved by Order no. 2416-A/2025 of 20 February; the qualified jobs and economic activities recognised by IAPMEI for line d) are set out in Notice no. 4812/2025/2.

The headline benefit is simple: while Portugal's progressive IRS can reach 48% plus surcharge at the top brackets in 2026, IFICI applies 20% for 10 years to net qualifying Category A and B income.

IFICI vs NHR — The Definitive Comparison

Many expats arriving in Portugal still ask about "NHR" — but the regime no longer accepts new registrations since 2024. The practical differences:

If you already hold NHR status (active until 2033), the benefit runs to its end. If you become a Portuguese resident in 2026, you can only apply for IFICI.

Who Can Benefit — The 6 Cumulative Conditions

Activating IFICI requires meeting all of the following conditions (Article 58-A(1), (10) and (12) EBF and Article 2 of Ordinance 352/2024/1):

1. Become a Portuguese tax resident under Article 16 CIRS — i.e., spend more than 183 days, consecutive or not, in any 12-month period starting or ending in the year concerned, OR maintain a home there in conditions suggesting intention to keep it as habitual residence.
2. Have not been a Portuguese tax resident in any of the previous 5 years. This includes both full and partial years. Someone who was a Portuguese tax resident in 2021 does not meet this requirement in 2026.
3. Engage in one of the qualifying activities under lines a) through g) of no. 1 of Article 58-A EBF (see next section). It is not enough to have income — it must flow from a qualifying activity.
4. Never have previously benefited from NHR or IFICI. This is a one-shot benefit — anyone who used NHR in the past is permanently barred from IFICI.
5. Not benefit from the Return Programme (Article 12-A CIRS, the regime for former residents returning to Portugal). The two regimes are mutually exclusive — worth comparing before deciding.
6. File the registration within the deadline — by 15 January of the year following the year residency was established.

Critical nuance regarding partial residency: if you move to Portugal in October, you are taxed as a resident only from the date of the move (partial-year residency, Article 16(3) CIRS). The 10 IFICI years count from the year you became resident.

Qualifying Activities — Lines a) Through g) of Article 58-A EBF

a) Higher education teaching and scientific research

Includes researchers at entities integrated in the National Scientific and Technological System (FCT-validated), scholars at recognised scientific institutions, and university faculty. Validator: FCT — Foundation for Science and Technology.

Professions and CAE Codes — Ordinance 352/2024 Annexes

Ordinance 352/2024 (amended by 52-A/2025) defines two operational annexes:

• Annex I — Highly qualified professions (Portuguese Classification of Occupations codes): 112 (chief executives of companies), 12 (administrative and commercial managers), 13 (production and specialised services managers, except 1349), 21 (science and engineering professionals, except 216), 2163.1 (industrial product or equipment designer), 221 (medical doctors), 231 (university and higher education teachers) and 25 (ICT professionals). Requires European Qualifications Framework level 8, or level 6 plus three years of proven professional experience (Article 7 of the Ordinance).
• Annex II — Eligible CAE codes (company, under line c) ii)): mining and quarrying (divisions 05 to 09), manufacturing (divisions 10 to 33), information and communication (divisions 58 to 63), research and development in natural sciences (group 721), higher education (subclass 85420) and human health activities (subclasses 86100 to 86904).

For tech founders, the most relevant CAE codes are 62.01, 62.02, 62.03, 62.09 (programming, IT consulting) and 63.11, 63.12 (data processing, web portals). Before signing a contract, verify that the employer's main CAE qualifies, that it exports at least 50% of turnover and that the profession is in Annex I — "Senior Software Engineer" as a title is not enough on its own.

The Tax Benefit in Detail

On Portuguese-source income

Special 20% rate on net Category A (employment) and Category B (self-employment) income from the qualifying activity (Article 58-A(2) EBF), with an option to aggregate. Withholding is 20% (Articles 99(8) and 101(1)(d) CIRS) but it is not final: the income is still reported on Modelo 3.

Not covered by the 20% rate:

• Portuguese-source dividends, interest and capital gains (Categories E and G) — subject to standard autonomous rates (generally 28%)
• Portuguese-source rental income (Category F) — 25% autonomous rate on residential leases (lower for long leases), 28% on other rentals, or aggregation
• Portuguese pensions (Category H) — ordinary progressive brackets
• Non-qualifying activity income (e.g. side work unrelated to the declared line)

On foreign-source income

Exemption with progression for Categories A, B, E, F and G of foreign source — income enters the average rate calculation but is not taxed in Portugal. Example: €30,000 foreign salary enters the rate calculation for Portuguese income but pays no Portuguese tax.

Critical exception — Category H (pensions): Foreign pensions are taxed at ordinary progressive rates. This is the headline change from the old NHR (which taxed at 10%). Anyone who moved to Portugal late-career for favourable pension treatment — IFICI is not the right regime.

Blacklisted jurisdictions: capital income and gains paid by entities in territories on the Ordinance 150/2004 list are taxed at 35% (Article 81(5) CIRS).

Specific Warnings for US and UK Citizens

US citizens — FEIE and Treaty interaction

US citizens remain subject to US worldwide taxation regardless of Portuguese residency. The Foreign Earned Income Exclusion (Form 2555) and US-Portugal tax treaty interact with IFICI in complex ways. Key points: (1) IFICI's 20% rate applies in Portugal but is not creditable beyond actual tax paid; (2) self-employment income remains subject to US SE tax (~15.3%) unless the totalisation agreement applies; (3) state tax residency must be terminated separately. Consult both a Portuguese CC and a US CPA before relocating.

UK citizens — no equivalent regime after non-dom abolition

Since the 2025 abolition of the UK's non-dom regime, IFICI is one of the most competitive expat tax regimes in Western Europe for UK nationals relocating. A new UK–Portugal double tax convention, signed on 15 September 2025 and approved by Portuguese Parliament Resolution 206-A/2025, replaces the 1968 treaty once it takes effect. The Foreign Income and Gains 4-year exemption in the UK does not extend to Portuguese residency periods. SIPP and ISA accounts continue under their UK rules; HMRC's split-year treatment for the year of departure must be coordinated.

Practical Examples — Your IFICI Savings

2026 comparisons for a single person with no dependants, resident in mainland Portugal, with Category A income. The standard regime applies the specific deduction (11% social security), the Article 68 brackets, the solidarity surcharge and €250 of general family expenses; IFICI applies 20% to net income (gross salary minus social security).

Case 1 — €50,000/year (junior expat engineer)

• Standard IRS 2026: about €11,190 tax
• IFICI: (€50,000 − €5,500) × 20% = €8,900 tax
• Annual savings: about €2,290. For this profile, IFICI pays off from about €35,000 gross a year.

Case 2 — €80,000/year (senior engineer relocating)

• Standard IRS 2026: about €23,060 tax
• IFICI: (€80,000 − €8,800) × 20% = €14,240 tax
• Annual savings: about €8,820 — close to €88,000 over 10 years on the same salary.

Case 3 — €150,000/year (lead developer or tech founder)

• Standard IRS 2026: about €53,780 tax, including the solidarity surcharge
• IFICI: (€150,000 − €16,500) × 20% = €26,700 tax
• Annual savings: about €27,080 — close to €270,000 over 10 years on the same salary.

How to Apply for IFICI — Step by Step

1. Confirm preliminary eligibility (alone or with a CC): tax residency in the last 5 years? Applicable line? Employer certified if line b/d?
2. Establish tax residency: Portuguese NIF, active address in the Portal das Finanças, and either the 183-day stay or the qualifying habitual home under Article 16 CIRS.
3. Begin the qualifying activity: sign the contract with the eligible entity or begin self-employment with a qualifying CAE (for freelancers).
4. File the registration request on the Portal das Finanças (model approved by Order 2416-A/2025), indicating the applicable line and attaching supporting documents (employment contract or commercial certificate, academic qualifications, etc.). Deadline: 15 January of the year following the year residency was established (Article 2(1) of Ordinance 352/2024/1).
5. Confirmation by the competent body: FCT, AICEP, IAPMEI, ANI, Startup Portugal or the Autonomous Region confirm the activity by 15 February; for line c), the employer confirms the requirements on the Portal das Finanças by 15 March.
6. Final AT decision: the Portuguese Tax Authority publishes the decision on the Portal das Finanças by 31 March, activating IFICI status for 10 consecutive years.
7. Annex L of Modelo 3: each annual IRS return, declare IFICI-subject income on Annex L with breakdown by category and source country.

Operational detail and screenshots in the IFICI Step-by-Step Annex L guide.

Critical 2026 Deadlines

Warning: missing the 15 January deadline shortens the 10-year window — the benefit only begins from the year of effective registration. No retroactive registration (Article 58-A(7) EBF).

Validating Bodies by Line

Annex L of Modelo 3

After IFICI status is activated, the annual obligation is completing Annex L of Modelo 3 IRS. It breaks down IFICI-subject income by:

• Category (A employment; B self-employment; E foreign capital; F foreign rental; G foreign capital gains; H foreign pensions)
• Type (applicable EBF Art. 58-A line)
• Source country of the income
• Gross amount and foreign tax paid (for exemption with progression)

The 10 years count from the year you became resident; with a late registration, the regime only applies for the remaining period (Article 58-A(2) and (7) EBF). Operational detail in IFICI Step-by-Step Annex L.

Social Security — What IFICI Does Not Cover

This is the single most common confusion. IFICI applies exclusively to IRS (income tax). Social Security contributions remain at standard rates:

• Employment (TCO): 11% employee + 23.75% employer on gross compensation
• Self-employed: 21.4% (Article 168(1) of the Contributory Code) on a monthly base equal to one third of the relevant income of the quarter (Article 163(1)); relevant income is 70% of service fees (Article 162)
• Company directors (MOE — board members): own regime with minimum quarterly base

For a software engineer earning €100,000 gross in PT under IFICI, the correct calculation is: €11,000 employee Social Security and (€100,000 − €11,000) × 20% = €17,800 IRS, leaving €71,200 net. Anyone who omits Social Security from planning is in for a surprise.

Foreign Income — Rules by Category

Common Mistakes That Cost the Benefit

1. Filing past the deadline — one year of the ten is lost, with no retroactive registration.
2. Confusing the company's CAE with the profession — under line c) ii) the profession must be in Annex I and the company must have an Annex II CAE and export at least 50% of its turnover.
3. Applying for IFICI with NHR history — anyone who used NHR is permanently barred.
4. Treating IFICI as a Social Security exemption — SS contributions always due.
5. Expecting benefit on foreign pensions — Category H pays ordinary rates.
6. Combining IFICI with the Return Programme — mutually exclusive.
7. Applying 20% to non-qualifying side income — only the declared activity qualifies.
8. Ignoring the 5-year rule — partial years count; anyone resident in PT in any of the prior 5 years is barred.
9. Stopping the qualifying activity — there is no benefit in a year without qualifying income; it can resume in the remaining years if qualifying income returns (Article 58-A(3) to (5) EBF).
10. Structuring without a CC — IFICI is often combined with a Portuguese Lda., international holding, or Madeira routing; without planning, most of the benefit leaks out.

Detailed analysis in 7 Common IFICI Mistakes.

IFICI vs Tax Alternatives

For a single person with no dependants earning a salary from a qualifying activity, IFICI pays off from about €35,000 gross a year (see the examples above). For people up to 35, IRS Jovem may be better in the early years — but anyone who benefits or has benefited from IFICI is barred from IRS Jovem (Article 12-B(9) CIRS), so the choice must be made before applying.

Business Bridge — Hiring Under IFICI in an RFAI/SIFIDE Company

A powerful combination: a Portuguese company certified for RFAI or SIFIDE hires a qualified professional, who activates IFICI under line c) i) (highly qualified profession in a company with RFAI investment) or line e) (R&D personnel with SIFIDE-eligible costs).

The company benefits: RFAI tax credit (up to 30% of qualifying investment) or SIFIDE (up to 82.5% of R&D expenses), in addition to normal payroll deduction. The employee benefits: 20% IFICI versus up to 48% under the standard regime. The State benefits: attracts qualified talent and investment.

This structure requires upfront planning — the role must appear in the RFAI/SIFIDE project plan, and documentation must be prepared before hiring to support the IFICI application under the correct line. More on corporate incentives in Tax Benefits for Companies.

3 Real Rejection Patterns

Cases observed by HVR and peer CCs in the first 24 months of the regime:

1. Company CAE not eligible. Engineer hired as CTO in an e-commerce startup. The company operates under CAE 47 (retail), which is not in Annex II, and has no RFAI investment — neither route under line c) applies. The profession qualifies, but the company does not. Application rejected.
2. Deadline missed through IRS confusion. A family relocates in May 2024 and assumes registration happens with the 2024 IRS return filed in May 2025. For people who became resident in 2024, the transitional deadline was 15 March 2025 (Article 12 of Ordinance 352/2024/1). Result: IFICI only applies from 2025, for the remaining period.
3. Insufficient substantive classification. Professional hired as "Senior Developer" but the contract describes duties as "maintenance of existing systems" — the AT rejects it because the role does not match code 25 of the Portuguese Classification of Occupations (ICT professionals). Lesson: the contract's job description is load-bearing.

Frequently Asked Questions

What is IFICI?

The Portuguese tax regime created by Law 82/2023 (Article 58-A EBF) that replaced NHR effective 1 January 2024. It provides a special 20% IRS rate on net qualifying Category A and B income for 10 consecutive years.

Who qualifies for IFICI in 2026?

Anyone who becomes a Portuguese tax resident, was not resident in the prior 5 years, performs an activity under lines a) to g), never used NHR or IFICI, and does not use the Return Programme.

What activities qualify?

Scientific research and higher education teaching, qualified jobs under contractual investment benefits, highly qualified professions (Annex I of Ordinance 352/2024/1) at RFAI companies or exporting companies with an Annex II CAE, activities recognised by AICEP or IAPMEI, R&D staff with SIFIDE-eligible costs, certified startups (Law 21/2023) and residents of the Autonomous Regions.

What is the application deadline?

15 January of the year following the year residency was established. Anyone who became resident in 2025 must file by 15/01/2026 (Article 2(1) of Ordinance 352/2024/1).

How does IFICI differ from NHR?

NHR covered broader professions and taxed foreign pensions at 10%. IFICI requires registration with the competent body (FCT, AICEP, AT, IAPMEI, ANI, Startup Portugal or the Autonomous Regions), has narrower professions, and taxes foreign pensions at ordinary rates.

How is foreign income taxed under IFICI?

Exemption with progression for Categories A, B, E, F, G; Category H (pensions) at ordinary progressive rates; capital income and gains paid by entities in territories on the Ordinance 150/2004 list at 35%.

Is Social Security included in IFICI?

No. IFICI only touches IRS. Social Security contributions are due in full: 11% employee + 23.75% employer (employment), 21.4% on a monthly base equal to one third of the relevant income of the quarter, which is itself 70% of service fees (Articles 162, 163(1) and 168(1) of the Contributory Code) — self-employed.

What if I miss the 15 January deadline?

No retroactive registration. The benefit applies from the year of registration and only for the remaining part of the 10 years (Article 58-A(7) EBF).
