IRS Form 3 Return (Declaração Modelo 3 de IRS)
Official proof of the annual IRS return submitted, with income and annexes. We collect up to three years.
What it is for
- Prove the income you declared in a credit or rental application.
- Review the details and annexes you submitted to the AT.
- Include the return and the corresponding assessment for the same year in a single application.
What it is
Form 3 (Modelo 3) is the annual form in which taxpayers report income and other information relevant to IRS, together with the applicable annexes. The official proof shows what was submitted once validated by the AT. A draft or a simulation does not have the same value.
How we collect it
We need the holder's NIF and Tax Portal (Portal das Finanças) password. We try to obtain the proof for the 3 most recent years available, in one PDF per year; if fewer are available, we collect those that exist.
Period: 3 most recent years.
Access required: Tax Portal (Portal das Finanças). Credentials are encrypted only during the collection and deleted at the end.
Things to note
The income year does not always match the year of submission. If a replacement return was filed, check which version you should present.
Frequently asked questions
Does the proof show the final tax due?
No. It shows the details submitted; the AT's final calculation appears in the assessment notice or assessment certificate.
What if I was exempt from filing an IRS return?
Confirm the exemption and request the income certificate provided for that case, rather than looking for a return that does not exist.
