When should the IFICI application be submitted?

By 30 June of the year following your registration as a tax resident. If residency starts in 2026, the IFICI application is filed on the Modelo 3 due by 30 June 2027 (Annex L).

What is Annex L of the Modelo 3?

Annex L is the IRS return section dedicated to special regimes — formerly NHR, now also IFICI. You indicate the eligible profession, activity code and income under IFICI separately from other Category A or B income.

What documents must I keep for IFICI?

Employment or service contracts with IFICI-eligible activity clause; diplomas and professional certificates; proof of prior non-residency in Portugal for the 5 preceding years (foreign tax returns); startup certification for startup-route applicants.

Can I apply for IFICI retroactively?

No. The regime applies from the year of registration as tax resident. Prior years remain subject to the general regime. This is why the timing of the residency change is critical — ideally 1 January.

Is IFICI automatic once I complete Annex L?

No. The AT validates the application and may request additional documents. If rejected, the taxpayer can file a graciosa appeal and a hierarchical appeal. With correct documentation, approval is nearly universal.

How much does accountant support for IFICI cost?

Cost varies with complexity. HVR offers a free initial assessment. Standard package (Modelo 3 + Annex L + ongoing support): from €300 + VAT. For monthly accounting clients, this is included in the plan.

IFICI Step-by-Step 2026 — Annex L Application

IFICI Step-by-Step 2026: Annex L, Activity Codes and AT Submission

Activating IFICI in Portugal in 2026 involves 5 steps: (1) confirm non-residency in the 5 prior years and an eligible profession, (2) become a Portuguese tax resident, (3) start an IFICI-eligible activity, (4) complete Annex L of Modelo 3 with the correct code, and (5) submit by 30 June. Approval activates the 20% flat rate for 10 consecutive years.

1. Verify prior eligibility

IFICI (Law 41/2024) has three cumulative requirements:

Non-residency in Portugal in any of the 5 years immediately prior. Proven by foreign tax returns and/or a tax residency certificate from another country.
Eligible profession — listed in Ordinance 352/2024. Includes scientific research, technological innovation, senior management of exporting entities, highly qualified professions (specific CAE codes), Startup Portugal-certified startups, qualified investment.
Become a Portuguese tax resident in the year of activation (>183 days or habitual residence with intent to stay).

Use the IFICI simulator to confirm whether your profession and income qualify.

2. Establish Portuguese tax residency

To activate IFICI in year N, residency must begin in N (not N-1 or N+1). AT criteria (CIRS art. 16):

Presence > 183 days in Portugal in a 12-month rolling period
Habitual residence in Portugal with intent to stay (independent of 183 days)
Registration via Portal das Finanças → Personal Data → Tax Address

Recommendation: changing residency on 1 January maximises the 12 months of the first IFICI year. Mid-year change creates dual-regime complexity for that year.

3. Start an IFICI-eligible activity

Before year-end, formalise the activity that gives access to IFICI:

Category A (employment): contract with a tech, R&D, certified startup or exporting company. The contract should explicitly describe the eligible function.
Category B (self-employment): open activity on Portal das Finanças with a CAE from the IFICI list. Qualified liberal professions (international law, strategic consulting, digital product design) may qualify under the ordinance.
Qualified investment: register the investment with IAPMEI or Banco de Portugal, create qualified employment, minimum €500k in certified VC or €500k + 5 jobs in a Portuguese company.

4. Complete Annex L of the Modelo 3

The Annex L of Modelo 3 is the document that activates IFICI on your tax return. Structure:

Section	Content	Note
Q.4	Regime identification (IFICI / former NHR)	Select IFICI for registrations from 2024 onward
Q.5	High-value-added profession	Indicate the exact code from Ordinance 352/2024
Q.6	Cat. A/B income under IFICI	Separated from other income
Q.7	Foreign income exempt / elimination method	Foreign dividends, interest, capital gains

Most common error: indicating a generic profession instead of the exact code. The AT rejects applications without a precise Ordinance code.

5. Submit and validate enrolment

Modelo 3 filing deadline: 1 April to 30 June of the following year. Via Portal das Finanças → IRS → Modelo 3 → Annex L.

After submission, the AT has 30 days for review. It may request additional documents.
Approval → IFICI status active in tax registration for 10 consecutive years.
Rejection → graciosa appeal within 120 days; hierarchical appeal within 30 days.

Verify enrolment: Portal das Finanças → My Tax Record → "Special Tax Regimes". Should display "IFICI — Start: Year X — End: Year X+9".

Evidentiary documents to keep

Employment/service contracts with IFICI clause
Diplomas, professional certificates and CV
5 years of foreign tax returns (proving non-PT residency)
Tax residency certificate from prior country (Form 6166 USA, Form NT UK, etc.)
For startups: current Startup Portugal certification
For investors: proof of qualified investment (IAPMEI/BdP)

The AT may request this documentation for up to 4 years after approval. Maintain a digital archive with copies.
