Agreed rent is one of the most advantageous tax mechanisms for landlords and tenants in Italy, yet it is still relatively unknown. In 2026, with rental rates in many Italian cities at all-time highs, understanding how the agreed rent contract works can make a significant difference. In this guide you will find everything: what agreed rent is, how the rent is calculated, the benefits of the reduced flat-rate tax at 10%, and when it is more advantageous than market-rate rent.
What Is an Agreed Rent Lease Agreement
The agreed rent lease agreement is a form of residential rental contract in which the rent is not freely determined by the parties, but set within limits established by Territorial Agreements between landlord organizations (Confedilizia, UPPI) and tenant organizations (SUNIA, SICET, UNIAT). These agreements, stipulated at the municipal level, define the rent ranges by geographic area, adjustment coefficients, and the rules for determining the actual rent. The governing legislation is Law 431/1998.
Types of Agreed Rent Contracts
3+2 Contract
The most common type. Duration of 3 years + 2 years of automatic renewal. Without notice of termination at least 6 months before expiry, the contract automatically renews for another 2 years.
Transitional Contract (1-18 months)
For documented transitional situations (work transfer, university studies, renovation). Duration from 1 to 18 months, renewable.
University Student Contract (6-36 months)
For out-of-town students enrolled in a university program. Duration from 6 months to 3 years, with the same tax benefits as the standard agreed rent contract.
How Agreed Rent Is Calculated
Step 1: Identify the Zone and Rent Range
Each municipality with a territorial agreement divides its territory into zones and defines a minimum and maximum rent per square meter for each zone.
Step 2: Determine the Contractual Surface Area
The surface area is weighted with reduction coefficients for terraces (25-35%), cellars, attics (50-75%). The result is the weighted commercial surface area.
Step 3: Apply the Adjustment Coefficients
Coefficients are applied for floor level, elevator, maintenance condition, year of construction, orientation, type of heating, parking space, cellar, and garden.
Formula
Annual Rent = Weighted Surface Area x Zone Base Value x Coefficients
Example (Milan, zone 5, 80 sqm, 3rd floor, good condition): Weighted surface area 75 sqm x €10.25/sqm/month x 1.10 = €845.63/month
Reduced Flat-Rate Tax: The Major Tax Advantage of 2026
The main advantage of agreed rent is the reduced flat-rate tax at 10%, which replaces:
- IRPEF (income tax) and municipal/regional surcharges on rental income
- Registration tax (normally 2% of annual rent x years)
- Stamp duty on the contract
Flat-Rate Tax 10% vs IRPEF: How Much Do You Save?
Scenario: Employed landlord, gross income of 35,000 euros, apartment rented at agreed rent of 800 euros/month (9,600 euros/year).
Option A – Standard IRPEF: Taxable base 9,120 euros (5% deduction), 35% tax bracket → tax on rent: ~3,192 euros + 192 registration = ~3,384 euros/year
Option B – Flat-rate tax 10%: 9,600 x 10% = 960 euros/year
Annual savings: 2,424 euros. Over 5 years: more than 12,000 euros!
Benefits for the Tenant
Lower rent: Agreed rent is typically 20-40% lower than market rate in major Italian cities.
IRPEF deduction: The tenant who signs an agreed rent contract as their primary residence can deduct up to €495.80/year (income ≤ €15,493.71) or €247.90 (income between €15,494 and €30,987).
Stability: Minimum duration of 3 years (renewable), greater security compared to transitional contracts.
Requirements to Access Agreed Rent
Property: Residential use, municipality with a Territorial Agreement, not luxury categories (A1, A8, A9).
Contract: Rent within the agreement ranges, registration with the Revenue Agency within 30 days, flat-rate tax option at registration, certification (in many municipalities).
How to Register the Contract
Within 30 days of signing, through: the online RLI service (agenziaentrate.gov.it), a Revenue Agency office, or an authorized intermediary (accountant, tax assistance center). With flat-rate tax, no registration tax or stamp duty: registration is free.
Agreed Rent and IRPEF Deductions 2026: 10% Flat-Rate Tax Confirmed
The 2026 Budget Law confirmed the flat-rate tax at 10% for agreed rent contracts. Particularly advantageous for landlords with total income above €28,000, co-owners (each share applies separately), and those who prefer tax certainty.
Agreed Rent vs Market-Rate Rent: When Is It Worth It?
Agreed Rent is worth it if: you are in a medium-high IRPEF bracket (above 27-35% marginal rate); the difference in rent is less than the tax savings; the property is in a municipality with an up-to-date territorial agreement.
Market-Rate Rent is worth it if: you are in a low IRPEF bracket (retiree with income below 15,000 euros); the market rent is much higher than the maximum agreed rent; the property is a luxury category (A1, A8, A9).

The Role of Certification
In many municipalities, certification of the contract is mandatory to access the tax benefits. It is an attestation by an organization that signed the agreement, certifying the correctness of the rent. Without certification, the tax benefits may be denied. Cost: 50-150 euros, amply repaid by the tax savings.
Practical Cases: How Much Do You Save?
Case 1 (Milan, average income): Landlord with 40,000 euros income, 70 sqm apartment. Market-rate rent 1,400/month → IRPEF taxes ~6,042 euros. Agreed rent 900/month → flat-rate tax 10% = 1,080 euros. Net balance: -1,038 euros/year. Market-rate rent is slightly more advantageous.
Case 2 (Rome, high income): Professional with 75,000 euros, 55 sqm one-bedroom apartment. Market-rate rent 1,200/month → IRPEF taxes 43% ~5,882 euros. Agreed rent 850/month → flat-rate tax = 1,020 euros. Net balance: +662 euros/year. Agreed rent is more advantageous.
Agreed Rent and Renovation Tax Credit
If you have renovated the property, you can continue to deduct renovation expenses (50% bonus over 10 years) even when opting for the flat-rate tax. Double tax savings: 10% flat-rate tax + renovation deductions.
How to Find Your Municipality's Territorial Agreement
Search on your municipality's website (under "Urban Planning" or "Housing Policies"), contact the Housing Office, or reach out to Confedilizia, SUNIA, UPPI, or SICET in your city.
Conclusion: Is Agreed Rent Worth It in 2026?
