Non-compliance no longer goes unnoticed

IMPIC has announced a protocol with the Portuguese Tax Authority that will let it cross-check real estate transaction data and verify who is licensed and who has met the obligations of Law 83/2017.

The tool is still being built, but past transactions remain on record: a sale the Tax Authority has without a matching IMPIC filing is detectable by comparison.

Failing to file is an offence punishable by a fine of €5,000 to €500,000 for legal persons.

What ComunicaPro gives you

Nothing goes unfiled

Every deed or contract gets its own status in your account: to extract, to review, XML generated. You see at a glance what is done and what is still pending before the quarter ends.

Errors caught before you submit

Every field appears next to the excerpt it was read from, and uncertain fields stay highlighted. The XML is only generated once you confirm everything, and a field with no information stays empty, never guessed.

The portal's exact format

The file comes out in IMPIC's official schema, with parish (DICOFRE) codes, property types and payment methods already resolved. You import it into the portal with no manual touch-ups.

How it works

1. Upload the document

Upload the deed or contract PDF (native or scanned). The document is handled securely and deleted after the retention period.

2. Automatic extraction

AI reads the document and extracts buyers, sellers, transaction and properties, mapped to the format IMPIC requires. Each field comes with its source excerpt.

3. Mandatory review

You confirm or correct each field next to the original text. Low-confidence fields stay highlighted until you verify them.

4. Download the XML

We generate the XML file in the portal's exact format. Submission and signing remain yours, on the official IMPIC portal.

Frequently asked questions

Can I try it without paying?

Yes. During the launch period, creating an account gives you 1 courtesy credit to prepare your first filing end to end: upload the document, review the fields and download the XML. No card required. This offer may end at any time.

By when do I have to file with IMPIC?

Real estate transactions are filed quarterly, by the end of the quarter following the one in which they took place: Q1 by 30 June, Q2 by 30 September, Q3 by 31 December and Q4 by 31 March the following year. The start of activity has its own deadline: 60 days from that date under article 46 of the law (IMPIC's website states 60 working days, a more generous reading). For tenancies, only contracts with a monthly rent of 2,500 € or more are filed. Source: Law 83/2017, amended by Law 58/2020, and IMPIC General Guidance no. 1/2021. Always confirm the deadlines in force on the IMPIC website.

Which documents can I upload?

The purchase and sale deed, the contract or the authentication deed (private authenticated document), as a native or scanned PDF. You can add the Caderneta Predial Urbana, the Certidão do Registo Predial and the Energy Certificate to sharpen the property fields. They are read in the same filing, at no extra cost.

Is the generated XML accepted by the IMPIC portal?

The file follows the portal's exact schema and is validated against real filings already accepted. It is imported into the portal form, which is then pre-filled; submission and signing remain yours. If the portal flags a correction, you adjust the field and generate the file again.
