Short answer: CAE codes support the IFICI file, but they do not decide it alone
An IFICI sector review should start with the activity actually performed, then map that activity to the relevant CAE or NACE code, employer or client evidence, qualification route, and competent verification authority. A matching CAE code helps, but IFICI eligibility turns on the legal route, real activity, evidence, and authority review. A CAE code is important evidence, but it is not a standalone entitlement. The practical file should answer four questions before filing:
Which IFICI route is being used?
What activity is actually performed in Portugal?
Which CAE or NACE code and documents support that activity?
Which authority is expected to verify the route?
IFICI Qualifying Sectors: What You Need to Know
Your eligibility for Portugal's IFICI tax incentive depends on multiple statutory factors, including activity classification, residency history, and implementation criteria in the current legal framework.
A job title alone does not establish eligibility. Check the work, the employer or project and the conditions for the applicable route.
This page helps you test whether your activity, CAE alignment, and pathway are likely to stand up before you rely on the incentive.
Book a Tax Position Review if you need the eligibility position documented before application or relocation decisions.

Which IFICI Route Applies to Your Work?
The legal routes are the seven subparagraphs of EBF Article 58-A(1). They are not seven interchangeable sector labels. All require the individual residence and regime conditions.
| Route | Activity and Entity Conditions | Code or Recognition Check | Competent Body |
|---|---|---|---|
| (a) Higher education, research and technology centres | University teaching or qualifying scientific research; also jobs directly involved in scientific research or innovation, or governing-body roles, in recognised technology and innovation centres | Establish the institution and actual activity; a CAE code alone does not decide this route | FCT |
| (b) Contractual productive-investment benefits | Qualified jobs or governing-body roles within the contractual investment-benefit framework | Match the job and approved investment project | AICEP |
| (c) Highly qualified professions | A profession in Portaria 352/2024/1 Annex I, meeting its qualification requirements, in a company benefiting from RFAI in the start year or previous five years, or a qualifying industrial/service exporter | For the exporter branch, Annex II main CAE plus at least 50% export turnover in the start year or either of the previous two years | AT, with employer confirmation |
| (d) Activities recognised as relevant to the national economy | Qualified jobs or governing-body roles in entities within the AICEP/IAPMEI notices | Apply those notices’ profession, activity and entity conditions; this list differs from route (c) | AICEP or IAPMEI |
| (e) Eligible R&D personnel | Personnel costs eligible under the specified SIFIDE provision | Prove the eligible R&D work and costs; not every technology role qualifies | ANI |
| (f) Certified startups | Jobs directly involved in scientific research or innovation, or governing-body roles, in an entity certified under Law 21/2023 | Confirm the entity’s startup certification and the individual’s actual role | Startup Portugal |
| (g) Autonomous regions | Jobs or other activities of tax residents in Madeira or the Azores | Apply the relevant regional legislation; the mainland CAE list is not an automatic regional test | Competent regional authority |
Scroll or use the arrow keys to compare all columns.
For route (c)’s exporter branch, Annex II uses CAE Rev. 3: extraction 05–09; manufacturing 10–33; information and communication 58–63; natural-science R&D 721; higher education 85420; human health 86100–86904. AT FAQ 5507 says to interpret that annex using CAE Rev. 3 and its explanatory notes. Do not substitute a current registration code without checking the correspondence.
An independent contract is not interchangeable with a statutory job. AT accepts university teaching under a services contract when the other conditions are met, but explains that a “posto de trabalho” requires employment. The route must be identified before employment, qualifications or CAE can be tested.

CAE Code Registration: the Technical Requirement
A CAE code (Classificação das Atividades Económicas) classifies an economic activity and is an important evidence element in IFICI activity mapping, but eligibility also depends on other statutory conditions.
Your CAE code is part of the evidence reviewed in IFICI applications, but it is not the only test. The legal starting point is article 58-A of the EBF, and the operational review then turns to the applicable annex, the activity actually performed, and the competent authority that reviews the file.
In practice, the CAE used in registrations and filings should match the real economic activity being carried on. A mismatch between the registered CAE, the role description, and the supporting documents can create problems even when the sector sounds close to a qualifying activity.
If your activity has changed, treat the CAE question as a record-keeping and evidence issue, not just a code-selection exercise. Update the registration and the underlying documents so the file tells one consistent story before the IFICI request is submitted.
Employed vs Self-Employed: Different Eligibility Paths
IFICI analysis is commonly structured across employed and self-employed scenarios, subject to the legal criteria for each case. The rules differ in critical ways.
Employed professionals may qualify when the role, activity and entity meet the conditions of the applicable IFICI route. Employment by a Portuguese entity alone does not establish eligibility.
Example: A software engineer can be blocked even when the role is technical if employer/pathway evidence does not satisfy current-year IFICI criteria. Reassessment can be possible in later years when criteria are met.
Self-employed professionals must confirm the eligible activity, its legal route and the supporting evidence.
Critical Restriction: Foreign freelancing does not qualify through every IFICI company path, but a self-employed taxpayer may qualify through a Category B activity path where its statutory conditions are met. Entity-related requirements depend on the applicable pathway and current implementing criteria, so this point should be validated against official guidance before filing.
Qualification and Evidence Requirements
Qualification thresholds depend on the legal pathway being used for the IFICI request.
Qualification is not checked in the same way for every IFICI pathway. Article 58-A and the current FAQ guidance tie the evidence burden to the activity and the competent authority reviewing the file, so the documents that matter can differ between teaching or research roles, highly qualified professions, innovation roles, and startup pathways.
Where the rules require proof of academic level or professional experience, the file should show both the qualification itself and how it connects to the activity being claimed. Foreign qualifications, professional records, and employer documents may all become relevant depending on the route being used.
The practical question is not just whether you hold a degree. It is whether the qualification, experience, activity, and entity all line up under the current rules. If one piece does not match, resolve that before filing rather than assuming the rest of the file will compensate for it.
Common Professions: Do They Qualify?
Treat profession examples as screening cues, not final determinations.
Profession labels are only a starting screen. IFICI analysis usually turns on the activity actually performed, the entity involved, the relevant CAE or other pathway criteria, and the authority that reviews the request.
Roles in software, engineering, research, higher education, health innovation, and other technical fields may sit closer to qualifying pathways, but the title alone does not decide the result. Administrative and commercial directors are expressly listed in Annex I for route (c), while the route (d) notices also list directors in hospitality, retail and other services. Each role must still meet its route’s profession, qualification and entity requirements.
If your role sits between sectors or mixes technical and non-technical functions, build the evidence first: activity description, employer information, CAE mapping, and documents that show what you actually do. That usually gives a more reliable answer than relying on profession-name lists.
The Verification Process: Which Agency Reviews Your Application
IFICI eligibility is reviewed by competent authorities designated in the current implementing framework. Confirm the authority for your activity and CAE mapping before filing.
The competent authority depends on the activity and entity involved. AT FAQ guidance lists different routes for higher-education and scientific activities, qualifying jobs in investment-related entities, highly qualified professions in certain companies, innovation roles, startup entities, and the regional regimes for the Azores and Madeira.
Because the authority changes by pathway, the first practical step is to identify the legal route before filing. Once that is clear, the registration request can be prepared with the activity description, entity information, and supporting documents that match that route.
If the pathway is unclear, solve that question before submission. In IFICI cases, filing under the wrong route creates avoidable delay because the authority reviewing the file is tied to the activity being claimed.

Frequently asked questions
Can I Change My CAE Code If It Does Not Qualify?
A CAE change can be relevant if your registered activity no longer matches the work actually being performed. The safer approach is to update the registration and supporting documents so they reflect the real activity, then assess IFICI from that factual base rather than treating the code change as a standalone solution.
Is IFICI Available for Contractors Hired Through Recruitment Agencies?
AT FAQ guidance says that when a pathway requires a qualifying posto de trabalho, that concept implies an employment contract. If you are providing services under a services agreement rather than an employment relationship, you should not assume the same IFICI pathway applies. The contract structure needs to be tested against the specific legal route being used.
What If My Company's Export Percentage Fluctuates Year to Year?
Employer-metric testing uses pathway-specific lookback and maintenance rules. Treat historical percentage examples as illustrative only and confirm current legal criteria before filing.
Can Secondary CAE Codes Affect My IFICI Eligibility?
For the exporter route in EBF Article 58-A(1)(c)(ii), the company's main activity must have a CAE code in Annex II of Portaria 352/2024/1; a qualifying secondary CAE alone is not enough. Other routes have their own activity and entity requirements. Confirm the route and the applicable CAE Rev. 3 classification before applying.
Do I Need a Portuguese University Degree to Qualify?
A Portuguese degree is not the only possible evidence. What matters is whether your qualification and experience satisfy the pathway you are relying on and whether the competent authority accepts the supporting documents for that route.
What Happens If I Lose IFICI Eligibility Mid-Year (E.g., Employer Export Threshold Drops)?
Article 58-A links the benefit in each year to continued Portuguese residency and continued income from a qualifying activity. If a qualifying condition changes, the effect should be reviewed against the current-year facts and the specific pathway before the next submission is made.
