Caderneta Predial: The Tax Record of a Portuguese Property Explained

Every property in Portugal has a Caderneta Predial, the official record kept by the Tax Authority (Autoridade Tributária, AT). It shows how the property is described for tax purposes, who is liable for its taxes and what it is worth in the eyes of the tax office. For buyers it is one of the first documents to check, because errors in it can affect taxes, financing and the sale itself.

Think of it as the closest equivalent to a US county assessor’s record or the UK council tax listing, but more detailed: it describes the property, its areas and use, and states its official tax value.

What is the Caderneta Predial?

The Caderneta Predial (also called “certidão matricial”) is the extract from the property tax register (matriz predial). There are three types:

• Caderneta Predial Urbana for urban properties: apartments, houses and building plots.
• Caderneta Predial Rústica for rural land.
• Mixed properties, such as a farmhouse with land, have both.

Each property has a matrix article number (artigo matricial) that identifies it in the tax system.

Caderneta Predial vs. Certidão Permanente

The two documents are often confused, but they serve different purposes:

Before buying, both must match each other and the reality on the ground. Differences in areas, owners or use are common, especially in older or rural properties, and must be resolved before the deed.

What the Caderneta Predial Urbana shows

• Holder: the person or company registered for tax purposes, with tax number.
• Location and identification: district, municipality, parish and matrix article.
• Description: type of building, whether it is divided into separate units (propriedade horizontal), number of floors.
• Unit details: floor or letter of the apartment, typology (for example T2 = two bedrooms), and its use (habitação for housing, comércio or serviços for commercial use).
• Areas: plot area, footprint, private gross area and dependent gross area.
• Tax value (VPT): the Valor Patrimonial Tributável, with the year of the valuation and the formula used.

Understanding the areas

• Private gross area (área bruta privativa): the area of the home measured to the outer walls, including rooms, kitchen, bathrooms, corridors and enclosed balconies. Open balconies, terraces and common areas are excluded.
• Dependent gross area (área bruta dependente): covered areas for exclusive use outside the main living space, such as a garage, parking space or storage room.

If the advertised size differs significantly from the caderneta, ask why before you sign anything. Extensions or converted spaces that were never declared are a frequent cause.

What the VPT means for you

The VPT is calculated with a legal formula that takes into account the location, area, use, quality and age of the property. It is usually well below the market price, and it matters in three ways:

• IMT and stamp duty are calculated on the higher of the purchase price and the VPT.
• Annual property tax (IMI) is a percentage of the VPT.
• Inheritance and gifts: stamp duty on inheritances is based on the VPT, not on the market value.

Owners can request a re-evaluation. Because the age factor reduces the value over time, this can lower your IMI, but it can also raise the VPT. Use the simulator on the tax portal before applying.

How to get the Caderneta Predial

• Online, free of charge, on the Portal das Finanças: log in with your tax number (NIF) and password, go to your property list (Património Predial) and download the caderneta as a PDF.
• At a tax office (Finanças), with ID and the matrix article.

Only the owner or someone acting for them can obtain it. As a buyer, ask the seller or the agent for a current copy before you make an offer.

Heirs, gifts and usufruct in the caderneta

After an owner dies, the caderneta usually shows the undivided estate (for example “Herança de …”) as the tax holder until the heirs have divided it. If the property was given away during the owner’s lifetime, the recipient appears as holder; if the donors kept a usufruct, the caderneta generally lists both the usufructuary and the holder of the bare ownership (nua-propriedade). A will that leaves the property to one heir is not shown while the owner is alive. Because the caderneta is a tax record, it does not decide who may sell: for that, the land registry certificate (Certidão Permanente) and the inheritance documents are decisive.

What buyers should check

1. Holder: is the seller the person shown?
2. Use: is the property classified for housing? A unit registered as an office or shop cannot simply be used as a home, and banks may not finance it.
3. Areas: do they match the listing, the land registry and the property itself?
4. Pool, annexes, extensions: are they included? If not, they may not be legal.
5. VPT: it determines your IMT if it is higher than the price, and your future IMI.

Keeping it up to date

After the deed, the change of tax holder is normally processed automatically, because notaries and the Casa Pronta service notify the Tax Authority. If your property still does not appear under your NIF a few weeks later, contact your lawyer or the tax office. Building works, extensions or a change of use must be declared to the Tax Authority with the IMI declaration (Modelo 1), generally within 60 days.
