Residential lease agreements in Portugal are primarily governed by the New Urban Lease Regime (NRAU, Law No. 6/2006), which came into force on 27 June 2006, as substantially amended by the Mais Habitação package (Law No. 56/2023), effective 7 October 2023. The fundamental requirement is that all urban leases must be in writing. This is not a recommendation — it is a mandatory statutory rule.
1. Written Form is Mandatory (Art. 1069 CC)
Residential Lease Agreement Process in national
Draft Written Lease Agreement
Prepare a comprehensive written agreement covering parties identification (full name, NIF, address), rental amount and payment terms, duration, permitted use, security deposit conditions, and termination provisions. The agreement must be written — oral leases are not enforceable.
Include Mandatory Elements
The lease must identify: both parties (with NIF/passport numbers), the property (matrix article, parish, full address), rent amount, payment method and IBAN, duration, and security deposit terms within the Law 56/2023 limits.
Register with Tax Authority (Modelo 2)
File Modelo 2 with the Tax Authority within the calendar month following signature. Stamp Duty (10% of the first month rent) is payable at registration.
Provide Energy Certificate (EPC)
Supply the tenant with the current Energy Performance Certificate (EPC) at contract signing. The EPC must be referenced in any property advertisement.
Keep Records of Move-In Condition
Prepare a signed property condition report with photographs (inventory report) at move-in. This is the essential document for resolving deposit disputes at move-out.
Article 1069 of the Civil Code establishes unambiguously: all urban lease agreements must be concluded in writing. An oral agreement — however long-standing and clearly understood by both parties — does not constitute a valid lease in Portugal.
Consequences for landlords who provide no written lease:
- The landlord loses the ability to enforce the agreement in court.
- Specific penalties apply under Portuguese law for failure to provide written form.
- The landlord cannot validly register the lease with the Tax Authority.
Law 13/2019 — Tenant Protection for Oral Leases: Under Law No. 13/2019, a tenant who has occupied a property for 6 months or more can prove the existence of a lease even without a written contract (e.g., through rent payment records, utility registrations, or witness testimony). Once proved, the landlord becomes bound to the statutory terms of the NRAU. This provision protects tenants from being left without legal status due to a landlord's failure to issue a written agreement.
2. Security Deposit and Advance Rent Limits (Law 56/2023)
Law No. 56/2023 (Mais Habitação) introduced specific caps on the financial obligations required at the start of a residential tenancy:
- Security Deposit (Caução): Maximum 2 months' rent.
- Advance Rent (Antecipação de Rendas): Maximum 2 months' rent.
- Combined, the maximum upfront financial requirement (excluding the first month's rent) is 4 months' rent (2 months deposit + 2 months advance rent).
Any requirement exceeding these limits is unlawful and exposes the landlord to regulatory penalties.
3. Tax Registration: Modelo 2 and Stamp Duty
All residential leases must be registered with the Tax Authority:
- Modelo 2 Declaration must be filed by the landlord by the end of the calendar month following execution.
- Stamp Duty (Imposto do Selo): 10% of the first month's rent is due at registration.
- 2026 Rent Ceiling for Tax Benefit: Under the Construir Portugal programme, landlords who rent at or below the national rent ceiling of €2,300/month qualify for the reduced 10% IRS flat tax rate on rental income. Rents above this ceiling are subject to standard IRS rates.
4. Minimum Lease Duration
Under Law 13/2019, residential leases have a minimum term of 1 year, with automatic renewal protections during the first three renewal cycles. A landlord cannot oppose renewal during the first 3 years of a long-term lease without specific statutory grounds.
