Rental Deposits in Portugal: Rules, Refunds and Tenant Rights

Renting a home in Portugal usually means handing over a lot of money upfront: the first month's rent, a security deposit (caução) and often rent in advance. Many landlords also ask for a guarantor (fiador).

This guide explains the rental deposit rules in Portugal, how much a landlord can legally ask for, how to make sure you get your deposit back, and your key rights as a tenant — including what may change under the rental law reform currently going through Parliament.

Key takeaways (current law, November 2026):

• The security deposit (caução) is capped at two months' rent.
• Advance rent (rendas antecipadas) is also capped at two months.
• At signing you may therefore pay up to five months: first month + 2 months deposit + 2 months advance.
• The landlord must return the deposit at the end of the contract, minus documented costs for damage beyond normal wear and tear or unpaid amounts.
• A government reform (approved in principle in Parliament on 30 September 2026) would allow three months' advance rent and remove the deposit cap — but it is not in force yet.

How much can a landlord ask for upfront?

Under current Portuguese law (Article 1076 of the Civil Code, as amended in 2022–2023):

Example: for a flat at €1,000/month, the most you can be asked for at signing is €5,000 (first month + €2,000 deposit + €2,000 advance rent).

Anything above these limits for a residential lease isn't legally enforceable under the current rules. In practice, demand in cities like Lisbon and Porto means some landlords push for more — know your rights and ask for everything in writing.

Deposit vs advance rent: what's the difference?

• Deposit (caução): a guarantee held by the landlord. It's returned to you at the end of the contract, minus any legitimate deductions.
• Advance rent (rendas antecipadas): rent for future months, paid early. It's not returned — it's used to cover those months (usually the first months or the last months of the contract, as agreed).

Make sure the contract states clearly which amount is the deposit and which is advance rent, and which months the advance covers.

Guarantors (fiador) and alternatives

Portuguese landlords often ask for a fiador — usually a person resident in Portugal, with income and/or property, who agrees to pay if you don't.

For newcomers without a local guarantor, common alternatives are:

• paying a larger share upfront (within legal limits);
• a bank guarantee (garantia bancária);
• rent insurance or guarantor services offered by some companies;
• showing proof of stable income: an employment contract, payslips or several months of bank statements.

What the rental contract must include

A residential lease must be in writing and should state:

• identification of landlord and tenant (with NIFs);
• the property address and its habitation licence (licença de utilização);
• the rent and payment date;
• the duration and renewal terms;
• the deposit and advance rent amounts;
• who pays condominium fees, utilities and repairs.

Contract registration: the landlord must register the contract with the Tax Authority (Finanças) and pay stamp duty on it. Once registered, you can see it in your Portal das Finanças area. Registration matters — it lets you deduct part of your rent on your IRS return and proves your address for immigration and other purposes.

Rent receipts: most landlords must issue electronic rent receipts (recibos de renda eletrónicos) through the Portal das Finanças. Ask for them.

Protecting your deposit: the move-in checklist

Your best protection is evidence. On the day you get the keys:

• Walk through every room with the landlord or agent.
• Take dated photos and videos of walls, floors, appliances, windows, bathroom and kitchen.
• Record meter readings (electricity, water, gas).
• Prepare an inventory (inventário / auto de entrega) listing furniture and appliances and their condition.
• Have both parties sign the inventory and keep a copy.
• Email the photos to the landlord so there's a timestamped record.

A cheap contents and liability policy is worth having too: it covers you if a leak from your flat damages the neighbours' — see home insurance in Portugal.

Getting your deposit back

Portuguese law doesn't set a fixed number of days for returning the deposit. The landlord must return it at the end of the contract, once the property has been handed back and any amounts owed have been settled. Many contracts specify a deadline (for example, 30 days) — negotiate one before signing if it's missing.

To get your deposit back smoothly:

1. Give proper notice to end the contract (by registered letter with acknowledgement of receipt — carta registada com aviso de receção — unless the contract allows another method).
2. Clean the property and repair any damage you caused.
3. Do a check-out inspection with the landlord and compare with the move-in inventory and photos.
4. Read the meters and settle final utility bills.
5. Return all keys and get a written handover receipt (auto de entrega das chaves).
6. Give your IBAN in writing and request the refund.

What can be deducted from the deposit?

Legitimate deductions:

• unpaid rent;
• unpaid utilities or charges agreed in the contract;
• repair of damage caused by the tenant (broken appliances, holes in walls, stains, missing furniture).

Not legitimate:

• normal wear and tear — faded paint, minor scuffs, ageing appliances;
• repairs the landlord was responsible for anyway (structural issues, damp caused by the building);
• general renovation before the next tenant.

If the damage costs more than the deposit, the landlord can claim the difference from you.

If the landlord won't return your deposit

1. Ask in writing — email, then a registered letter with acknowledgement of receipt — stating the amount and a deadline.
2. Ask for an itemised list of deductions with invoices or quotes.
3. Seek help from:
   • DECO PROteste (consumer association);
   • tenants' associations such as Associação dos Inquilinos Lisbonenses (AIL) or the Associação dos Inquilinos e Condóminos do Norte de Portugal;
   • a Julgado de Paz — small-claims courts for disputes up to €15,000, with lower fees and faster decisions;
   • a lawyer, if the amount justifies it.

Keep all your evidence: contract, inventory, photos, payment receipts and correspondence.

Your key rights as a tenant

Under the current rules (NRAU and the Civil Code):

• Minimum duration: contracts for permanent housing are normally for at least one year.
• Renewal: unless agreed otherwise, contracts renew automatically; the landlord can't oppose the first renewal in a way that makes the tenancy shorter than three years, except in specific cases (e.g. needing the home for their own or their children's residence).
• Ending the contract early: after one-third of the contract term, you can leave with 120 days' notice (contracts of one year or more) or 60 days' notice (shorter contracts).
• Rent increases: during a contract, rent can be updated once a year by no more than the official coefficient published by INE, with 30 days' written notice.
• Repairs: the landlord is responsible for structural repairs and keeping the property habitable; you're responsible for minor maintenance and damage you cause.
• Privacy: the landlord can't enter without your consent, except as provided in the contract or in emergencies.
• Harassment (assédio no arrendamento) — e.g. cutting utilities to force you out — is prohibited.
• Tax deduction: if your contract is registered, a share of your rent can be deducted on your annual IRS return.

Proposed 2026 rental law reform

In July 2026 the government approved a proposal to reform the rental market (Proposta de Lei 103/XVII). It was approved in principle (na generalidade) by Parliament on 30 September 2026 and is now being discussed in committee, where it may still change before a final vote.

Main proposals affecting deposits and new contracts:

Until the reform is published and in force, the current limits apply. Don't accept terms based on rules that don't exist yet, and check the status before signing a new lease.

Rental scams to avoid

• Never pay a deposit before seeing the property (in person or via a live video call with someone you can verify).
• Be wary of prices far below market, landlords "abroad" who can't show the flat, or requests to pay via money-transfer services.
• Ask for the landlord's ID and NIF, and check the caderneta predial or land registry certificate to confirm they own the property.
• Pay by bank transfer to an account in the landlord's name and keep receipts.

Information is current as of November 2026. The rental law is under review — check the latest status before signing a contract.
