The process of buying a property involves more than the sale price: you must account for several purchase taxes and verify eligibility for any discounts. This article explains how the tax base is constructed, which rates apply for purchases from private sellers versus companies, and the main rules that govern the first-home benefit. We also include a numeric example to make the calculations concrete and flag the most common pitfalls that can lead to the loss of benefits. For legal reference and deeper checks, consult the specified regulations or a professional.
Before diving into percentages it helps to understand a couple of core concepts. The taxable base is often not the same as the money you pay. Instead it depends on the rendita catastale (the official cadastral income) updated by coefficients to produce the cadastral value, and on the price-value principle, which picks the higher of declared price and cadastral value for tax calculation. Knowing which number governs the calculation is the first step to estimating the registration tax, the mortgage tax, the land registry tax, or VAT when applicable.
How the taxable base is built
Start from the rendita catastale and apply the regulatory update factor and the proper multiplier for the property category. For typical residential purchases the procedure is: multiply the rendita catastale by 1.05 and then by the multiplier — for example 115.5 for first-home eligible units and 126 for most other residential properties — to get the cadastral value. The applicable tax base becomes the greater of this computed cadastral value and the price declared in the deed, following the price-value principle. That figure feeds the percentage or fixed taxes explained below.
Rates, fixed charges and a worked example
Rates depend on who sells (private individual or company) and on whether the purchase benefits from the first-home regime. For acquisitions from a private seller the common rule is a registration tax of 2% on the taxable base for first-home purchases and 9% for other homes. Typically the mortgage and land registry fees from a private seller are nominal fixed amounts (commonly €50 each), while for second homes these can be proportional (for instance mortgage tax 2% and land registry tax 1%). There is also a statutory minimum tax, often around €1,000, which can affect low-value transactions.
To make this tangible, imagine a property with a rendita catastale of €600. The computed cadastral value would be 600 × 1.05 × 115.5 = €72,765. If you buy that unit as a first home from a private seller, the registration tax at 2% is 72,765 × 2% = €1,455. Add the typical fixed mortgage and land registry fees of €50 each for a total of €1,555, noting the minimum tax rule could change small totals. This example shows why declared price may matter only when it exceeds the cadastral value.
Purchases from companies and when VAT applies
When the seller is an enterprise acting in construction or renovation, the sale is often subject to VAT instead of the registration tax. The reduced VAT rate for eligible first-home transactions is 4%, while other reduced rates like 10% can apply in specific cases and the standard rate applies elsewhere. In these transactions, registry, mortgage and land registry duties are frequently set as fixed sums (for example, around €200 each) on top of VAT, but actual figures depend on the seller’s tax position and the nature of the sale, so verify with the contract and the notary.
First-home benefit: conditions and special rules
The first-home benefit cuts taxes substantially but requires precise compliance: you must commit to moving your registered residence into the municipality of the purchased property within 18 months, the dwelling must not belong to excluded luxury categories (such as A/1, A/8, A/9), and you generally cannot already be the owner of another home in the same municipality, with some exceptions. Recent rules in the 2026 Budget Law also allow someone who previously used the benefit to reapply in specific circumstances if they sell the earlier house within 2 years of the new acquisition; such commitments are often recorded in the deed as binding undertakings. These conditions must be satisfied or the advantages can be withdrawn.
Risks, recoveries and practical advice
Failing to meet the requirements leads to a recovery of the saved taxes plus interest and penalties; inaccurate declarations can trigger sanctions. Remember that purchase taxes themselves are not generally tax-deductible, while mortgage interest may be deductible within statutory limits. Online calculators provide a quick estimate but remain indicative: always compare results with the notary’s fee estimate and consult a tax advisor or accountant. For legislative references consult D.P.R. 131/1986, D.P.R. 633/1972, D.Lgs. 347/1990 and the provisions in the 2026 Budget Law; consider that the last confirmed update on applicable rates was recorded on 26 May 2026.
