Buying a house requires far more than agreeing a sticker price: the fiscal framework can change the final outlay significantly. This guide offers a focused overview of the main elements to check before signing the notarial deed: IVA versus registration tax, the mechanics of the price-value
system, and the conditions that unlock first home benefits. Understanding the tax base and the seller’s tax regime is the first practical step to estimate what you will actually pay at closing and to plan any follow-up actions with your notary or tax advisor.
Which tax applies: registration tax or IVA?
The deciding factor for whether you pay IVA or the registration tax is not the intended
use of the property but the seller’s tax treatment. If you buy from a private individual or from a seller who transfers the asset exempt from VAT, the transaction is typically subject to registration tax. Conversely, if the sale is within the scope of VAT, then IVA becomes the primary levy and the registration, mortgage and cadastral taxes are paid as fixed amounts. It is essential to verify the seller’s declared regime in the preliminary
contract because the calculation basis changes: IVA uses the contracted price, while registration tax may use either the price or the price-value mechanism.
Practical rates and when to check them
Knowing typical rates helps you compare alternatives before committing. Under the ordinary rules, a sale not subject to VAT is charged a registration tax of 9% with a legal minimum of €1,000. For VAT-applicable sales, standard IVA rates are often 10% on ordinary dwellings and 22% for properties classified as high-end categories (A/1, A/8, A/9). These percentages can change when the purchase qualifies for the first home relief, provided the buyer meets the specific conditions. Always confirm the regime listed in the contract because it alters your final cash need and may influence whether further negotiations are warranted.
First home benefits: rules and limits
To obtain first home relief you must satisfy both objective and subjective criteria: the property must not belong to luxury categories (A/1, A/8, A/9) and must be located in the municipality where the buyer already has residence or intends to transfer it within a prescribed period, declared at closing. The buyer must also not own another property eligible for the same benefit within the same municipality. When conditions are met, taxes fall substantially—often a 2% registration tax or a reduced IVA rate of 4%—and the accessory fixed charges are lower. Note that one domestic outbuilding or parking space in the related categories may be included in the benefit but subject to statutory limits.
Deadlines, withdrawals and penalties
Benefits can be lost if you fail to meet timing requirements. If the relief is revoked, the buyer must pay the unpaid taxes plus interest and a penalty—commonly 30%—on the amount due. Recent legislative change extended certain timing rules: for instance, Law 207/2026 lengthened the window for disposing of a prior property from one to two years when you buy before selling. Other deadlines, such as the one-year remedy for repurchasing a first home without losing relief if sold within five years, remain unchanged. Always reconstruct the sequence of transactions and check deadlines with your notary to reduce risk.
Price-value and how to run the numbers
When the sale is not subject to IVA and the buyer is a private individual acting outside a business activity, the tax base can be the cadastral-derived value rather than the contract price; this is known as the price-value regime. The formula applies coefficients to the cadastral income: for a qualifying first home the computation typically involves the cadastral income × 1.05 × 110, while for other residential properties a coefficient of 120 is used. Because the tax base is lower under this system in many cases, the resulting registration tax may drop sharply and reduce exposure to valuation disputes by the tax authorities.
Practical advice before the deed
Before the notarial deed, reconstruct the chain of events: confirm the seller’s tax regime, verify whether you meet first home requirements, and request a professional valuation comparing market price and the cadastral value. Discuss the options with your notary or a fiscal consultant so you can opt—when available—for the solution that minimizes total cost and legal risk. In complex cases, a valuation report and a specialist opinion can prevent costly post-closing adjustments and sanctions.
