Modelo 3 is the annual personal income tax return in Portugal. The ordinary filing window for 2025 income ran from 1 April to 30 June 2026 and has now closed. For a late or replacement return, contact us before paying to confirm the next step. Residents usually report worldwide income; foreign-source income normally goes through Anexo J, and IFICI or grandfathered NHR positions may require Anexo L. Before filing, confirm:
Resident or non-resident status
Income category and country of source
Anexo J foreign-income mapping
Treaty or foreign-tax-credit position
e-Fatura and payment references

Frequently asked questions
Is this the U.S. IRS?
No. Here, “IRS” refers to Portuguese personal income tax (Imposto sobre o Rendimento das Pessoas Singulares). This service is for Portugal’s annual tax return (Modelo 3), filed online via the Portal das Finanças.
Which year is this for?
This is for income earned in 2025 (filed in 2026).
What is the filing deadline?
The ordinary deadline to file the return for 2025 income was 30 June 2026. If you still need to file or correct a return, contact us before paying so we can confirm the procedure, work required and availability. Specific statutory extensions may apply when their conditions are met.
How is foreign income handled?
Foreign-source income of Portuguese tax residents is generally reported through Anexo J, alongside other annexes required for the income and regime involved.
Can I file jointly with my spouse or partner?
If you are filing as a couple, we confirm the relevant filing basis in intake before preparation. The correct route depends on your legal and tax status and should be checked against your facts before filing.
I have NHR or another special regime. Does that affect my return?
An existing NHR registration with remaining years, or a case covered by the transitional provisions, can affect the treatment and annexes of your return. IFICI has its own conditions. We identify the applicable regime and necessary records before preparing the return; residence or a visa alone does not establish eligibility.
Can you guarantee a refund or a specific outcome?
No. Outcomes depend on your facts, documentation, and tax authority assessment.
What if I have U.S. obligations after buying Portugal-only filing?
If you have not paid yet, contact us to confirm the Portugal + U.S. scope: Taxbordr prepares the Portuguese return and a partner prepares the U.S. federal return. If you already paid for Portugal-only filing, contact us before buying another product so we can confirm the additional work and avoid duplicate payment.
Where can I check the filing service and its scope?
See the Annual Portugal Tax Return service for the work included and agreed separately. For a late or replacement return, contact us before paying.
