Tool 06 For sellers
From cadastral income to market.
The cadastral income (rendita catastale) is the figure the land registry assigns to a home; multiplied by a statutory coefficient it becomes the cadastral value, the basis for taxes. Here we calculate it and set it next to the OMI quotations: it is almost always much lower, and it is not a price.
- 01Where to read itIn the cadastral record (visura catastale): you can download it free, with the data on your properties, from the Revenue Agency's «Consultazione personale» service, with SPID, CIE or CNS.
- 02What to look forThe line for the dwelling: category (A/2, A/7…), class, size and «rendita» in euros.
- 03AnnexesCellar, garage and parking space have their own income (C/2, C/6, C/7): add it if they are sold together.
The sum of the incomes of the dwelling and of the annexes sold with it.
The multiplier drops from 120 to 110.
OMI quotations for the same home
Zones are described in words: the official boundaries are on the Agency's GEOPOI map. Choose the description closest to your home.
OMI quotations are on gross area: walls included, balconies and annexes in part. It is not the net walkable area.
Cadastral value
€151,200
€1,200 × 1.05 × 120
Under prezzo-valore, from a private seller: registration tax 9% = €13,608.
OMI quotations for the same home
€198,000 – €288,000
The cadastral value is 62% of the middle of the OMI range.
The cadastral value comes from an income set by the land registry and statutory coefficients: it does not follow the market and ignores view, condition and garden. It is used to calculate taxes, not to set a price.
Cadastral value: €151,200 · 198,000 – 288,000 €
How we calculate
Cadastral value = income × 1.05 × 120, or × 110 if the home will be the buyer's main home. The 1.05 is the statutory 5% revaluation; the multiplier applies to dwellings and their annexes, as the Revenue Agency's guide states.
Under prezzo-valore (Law 266/2005, art. 1 para. 497), in sales of dwellings and annexes between private individuals, taxes are paid on this value instead of the price: registration 9% or 2%, with a minimum of €1,000. The real price must still be declared in the deed.
The comparison uses the OMI quotations for the zone and type you choose, multiplied by the gross floor area: the ratio is between the cadastral value and the middle of that range. It does not say what the home is worth: it says how far the tax base is from market estimates.
For other categories (offices, shops, warehouses) the coefficients differ: we have not re-read them on an official source and the calculator does not use them.
