How to download your Agregado Familiar Comprovativo from AT

Your Agregado Familiar Comprovativo is AT's record of your household composition for a given tax year. Descodify accepts it as the strongest evidence for household confirmation.

Before you start

You'll need access to Portal das Finanças with your usual credentials.

Step by step

1. Open the Agregado Familiar page

Open the page directly: irs.portaldasfinancas.gov.pt/dadosagregadoirs/agregadofamiliar/consultar. If you're not signed in, AT sends you to its login page first.

2. Sign in

Sign in to Portal das Finanças with your usual credentials.

3. Pick the right year

Select the tax year you want to view and search. For your 2025 IRS filing (submitted between April and June 2026), pick 2025.

4. Identify your document

You'll see one or two rows for the year:

• MGAG…, with the status Pré-preenchimento.
• AGR…, with the status Confirmado.

If you have both for the same year, upload the most recent one.

5. Download the PDF

Download the comprovativo for the row you want. It comes as a PDF.

6. Upload to Descodify

Back on the Confirm step of your IRS filing, expand "Something changed? Verify with AT" and drop the PDF into the upload zone. Descodify extracts the values and shows them alongside your previous filing so you can spot any differences.

If something goes wrong

• Nothing shows up for the year you picked. AT may not have a record for that year yet.
• The download fails silently. Try a different browser or disable any VPN/extension that might block PDF downloads.
• The PDF opens but doesn't parse in Descodify. That likely means AT changed the layout. Send us the file and we'll update the parser.
