How to Apply for IFICI in Portugal - 2026 Step-by-Step Guide
How to apply for IFICI - the 2024+ replacement for NHR. Eligibility, documentation, registration, and yearly re-validation steps.
Contents
IFICI (Incentivo Fiscal à Investigação Científica e Inovação) is Portugal’s tax incentive for new tax residents working in scientific research, qualified innovation roles, and certain technical activities. Introduced in 2024 to replace NHR (which closed to new applicants), IFICI offers a 20% flat IRS rate on qualifying income for 10 years plus exemption on most foreign-source income.
Unlike NHR (registered once, valid for 10 years), IFICI requires annual re-validation - you confirm your eligibility each tax year. This guide walks through both the initial application and the yearly renewal.

Eligibility - the gate to clear
Three conditions must all be true:
- You’re newly resident in PT - became a tax resident in the year of application or the immediately preceding 5 years, AND haven’t been a PT tax resident in the 5 years before that.
- Your work qualifies - see HVAA list for which CPP codes are eligible. IFICI is NARROWER than NHR - only ~6 of the original 17 HVAA categories qualify (mainly STEM, ICT, academic).
- You’re physically resident in PT - meet the 183-day rule or have your “centre of life” here.
Path A - Initial application (year you become eligible)
Confirm tax residency status
By the end of the calendar year, you must be on file with AT as a Portuguese tax resident. Steps:
- Move to PT physically and stay >183 days
- Register your morada fiscal in PT at AT (see fiscal address guide)
- Have a PT residence permit or EU citizenship (CMT, AIMA TR, etc.)
AT auto-recognizes residency if these conditions are met by 31 December.
Verify your CPP code is on the IFICI eligible list
Check the HVAA list article for the IFICI-eligible subset - it’s flagged in the table.
Eligible categories (rough summary):
- Code 21 - Specialists in physical sciences, mathematics, engineering
- Code 25 - ICT specialists (must be in qualifying R&D/innovation context)
- Code 31 - Technical professionals (intermediate STEM)
- Code 35 - ICT technicians
- Code 231 - University professors
- Specific scientific research/innovation roles per IFICI Portaria
If your CPP isn’t on this list, IFICI doesn’t apply - you’d be on standard regime instead.
Gather supporting documentation
AT (or, depending on activity type, FCT or AICEP) reviews supporting evidence:
- Employment contract showing the qualifying role
- CPP code declaration (your employer’s classification of the role)
- Diploma or 5+ years professional experience evidence
- NIF + comprovativo de residência fiscal (residency certificate)
- For self-employed: client contracts showing the qualifying activity, plus Modelo 3 declarations from prior years
- For researchers: institutional affiliation letter, publication track record
Keep all originals - AT can audit anytime in the 10-year window.
Submit the IFICI declaration via Anexo L of Modelo 3 ↗
You don’t pre-apply at a separate IFICI page. Instead:
- File your annual IRS declaration as normal (Modelo 3)
- Tick the “IFICI” box on the Rosto
- Fill Anexo L with the declaration of qualifying activity
- Submit by 30 June
AT then reviews. If approved, the 20% flat rate applies retroactively to the entire tax year - you may get a refund vs the standard rate.

Wait for AT validation
Processing time: 3-6 weeks typically. AT may:
- Approve silently (most common) - no notification, status active in your AT profile
- Request more documentation - you respond via the portal
- Reject - usually because CPP code isn’t IFICI-eligible
Once approved, your AT profile shows “Regime IFICI: ATIVO” with the 10-year window end date.
Path B - Yearly re-validation
Each year of the 10-year window, you must:
- Submit Anexo L again with your annual IRS declaration
- Confirm continued qualifying activity - same role, same CPP, or updated info if you changed jobs but still qualify
- Keep employment / contract documentation up to date
If you stop qualifying mid-window (took a job outside the eligible categories, left PT residency, etc.), you lose the IFICI benefit for that year onwards. AT auto-detects via your annual filings.
Common mistakes
Applying when CPP doesn’t qualify. Common with junior IT roles or general consulting. Your job description matters more than your title - “general software engineer at a non-research company” may not qualify even though the CPP code 25 is on the list. AT looks for genuine research/innovation context.
Not having residency status confirmed before filing. If you became PT tax resident October 1 of the year you’re filing for, but didn’t update morada fiscal until after 31 December, AT may consider you non-resident for that year. Update the fiscal address as soon as you move.
Mixing NHR and IFICI. You can’t be on both. If you have legacy NHR, stay on it for the remaining years; switching to IFICI usually doesn’t help unless your situation has fundamentally changed.
Not declaring foreign income. IFICI exempts most foreign passive income from PT tax. But you still need to declare it on Anexo J - just with the IFICI marker that flags it as exempt. Skipping the declaration entirely triggers an audit.
How IFICI compares to alternatives
For a €60k freelancer in qualifying activity:
| Regime | IRS owed |
|---|---|
| Standard (no benefits) | ~€11,652 |
| NHR (legacy, if you had it) | €9,000 (20% × €45k taxable base) |
| IFICI (2024+) | €9,000 |
| Year-1 simplified regime | ~€2,000 (year-1 reduction stacks differently) |
For most qualifying applicants, IFICI replaces what NHR would have provided. The narrower scope means fewer people qualify, but for those who do, the savings are identical.
When to talk to a contabilista
Cross-border specialists who handle IFICI applications charge €500-€1,500. Worth it if:
- Your CPP code eligibility is ambiguous
- You’re a US citizen (worldwide-tax complications)
- You have foreign-source income that may need IFICI’s exemption to be fully optimized
- You’re transitioning from NHR to IFICI at the end of a 10-year window
For straightforward cases (clearly eligible CPP, single-source PT income, no foreign streams), DIY filing via Anexo L works fine.
