The short answer: ActivoBank is the best free Portuguese account (Conta Simples: €0/month, real PT IBAN, MB WAY). Millennium BCP is the best full-service bank for expats (non-resident accounts, ~695 branches, English-speaking staff in Lisbon/Porto). Wise is the best add-on for international transfers (real PT50 IBAN, mid-market rate, 0.35–0.6% fee). Revolut works for travel spending but don't rely on it alone. Everyone needs a NIF first.
Portugal remains one of Europe's top expat destinations — digital nomad visas, the Algarve, Lisbon's tech scene. Banking here is refreshingly simple once you have two things: a NIF (Número de Identificação Fiscal, the tax number) and, ideally, a Portuguese IBAN. This guide compares the accounts expats actually open — ActivoBank, Millennium BCP, Caixa Geral de Depósitos, Novo Banco, Santander Portugal, Banco BPI and Banco CTT — plus where Wise and Revolut fit in your setup. Fees are real, sourced from current bank tariffs; where a fee says "check current tariff", tariffs genuinely vary by product.

1. ActivoBank — the best free Portuguese account
ActivoBank is the digital arm of Millennium BCP and the closest thing Portugal has to a free lunch in banking: Conta Simples costs €0/month with no card fees, a full Portuguese IBAN and MB WAY support. The app is genuinely good, and because it sits on Millennium's licence your deposits get the same €100,000 FGD protection.
The catch is onboarding: fee-free online opening is designed for residents. Non-residents can be accepted but usually need to visit a Millennium branch or meet the bank's customer-acceptance policy (a 2026 Portuguese-SIM requirement for remote onboarding has been reported). If you're already in Portugal with a NIF, it's a 15-minute job in the app.
2. Millennium BCP — best full-service bank for expats
Portugal's largest private bank (~695 branches) is also its most expat-ready: it explicitly serves non-residents, offers mortgage products for foreigners buying property, and has offices in Lisbon and Porto known for smooth foreigner onboarding. UK expats get a bonus — Millennium has a London office where account opening can start.
You'll pay more than at ActivoBank (fees depend on the account package — check the current tariff), but you get face-to-face service, English-speaking staff in the big cities, and a bank that has seen every expat paperwork situation before. Non-residents typically need a passport/EU ID, Portuguese NIF, proof of address and proof of income.
3. Caixa Geral de Depósitos (CGD) — biggest network, state-owned
CGD is Portugal's largest bank by assets and is wholly state-owned, with offices in virtually every town — including rural areas where nothing else exists. Its Conta Extracto runs about €4.95/month. Some relocation sources describe CGD as relatively open to non-EU applicants; others report notoriously slow in-branch onboarding for foreigners. Both can be true — it varies enormously by branch.
4. Wise — best for international transfers
Wise is the only non-bank provider issuing a real PT50 IBAN, which means transfers in and out behave like a local account. There's no monthly fee; you pay a transparent 0.35–0.6% on conversions at the mid-market rate — typically €300–€1,500/year cheaper than old-school SWIFT wires on a normal expat transfer pattern. You can open it from abroad before you move.
One honest caveat: Wise is a payment institution, not a bank — your money is safeguarded in segregated accounts but is not covered by the €100,000 deposit guarantee. Use it as your currency hub, not your life savings vault.
5. Revolut — good travel card, weak primary account
Revolut Standard is free and handy for multi-currency spending, but mind the limits: a €1,000/month weekday free-conversion cap and a 1% weekend markup bite if you move real money through it. Portuguese IBANs have been rolling out, but historically its foreign IBAN caused friction with landlords and utilities.
Also worth knowing
Novo Banco (Conta DO Normal, ~€5.18/month) and Santander Portugal (Conta Base, ~€5.30/month) are solid mainstream alternatives — Santander especially if you already bank with Santander elsewhere in Europe and want cross-border familiarity. Banco BPI (~€6.25/month for Conta Base BPI) is fine but pricier; Banco CTT, the post office's bank (~€5/quarter with waiver conditions), is a quiet low-cost option with MB WAY support.
The NIF: get this before anything else
No NIF, no bank account — it's that simple. The Número de Identificação Fiscal is required for virtually every financial contract in Portugal. Residents get one at a Finanças (tax office) counter; if you're still abroad, a fiscal representative (a lawyer or relocation service) can obtain it for you. Do this weeks before your move — it's the single most common reason expat account openings stall.
Why a Portuguese IBAN (and MB WAY) matter
Portugal runs on MB WAY — the instant mobile payment system used for everything from splitting restaurant bills to paying the electrician. It works best with a Portuguese account and phone number. A PT IBAN also sidesteps IBAN discrimination: some landlords, employers and utilities still balk at foreign IBANs despite it being illegal under EU rules. Wise's PT50 IBAN or any local bank account solves this; a foreign-IBAN-only setup invites friction.
Deposit protection
Licensed Portuguese banks are covered by the Fundo de Garantia de Depósitos (FGD) up to €100,000 per depositor per bank — the EU-wide standard. Spread larger sums across banks if needed. Remember: fintechs like Wise safeguard funds but don't carry deposit insurance.
FAQ
Can an expat open a bank account in Portugal before arriving?
Sometimes, but plan for an in-person visit. Millennium BCP serves non-residents and even has a London office for UK expats. You'll still need a Portuguese NIF, obtainable via a fiscal representative. Wise or Revolut can be opened from abroad for a working EUR IBAN in the meantime.
What is a NIF and do I need one for a bank account?
The NIF (Número de Identificação Fiscal) is the Portuguese tax number, and yes — banks require it even for non-residents. Get it at a Finanças counter in Portugal or through a fiscal representative before you move.
Which Portuguese bank is free for expats?
ActivoBank's Conta Simples: €0/month, no card fees, Portuguese IBAN and MB WAY. It's Millennium BCP's digital brand. Note fee-free online onboarding generally needs residency documents.
Do I need a Portuguese IBAN, or is Revolut/Wise enough?
A PT IBAN makes daily life smoother — landlords and utilities can be difficult about foreign IBANs, and MB WAY works best with a local account. Wise issues a real PT50 IBAN; Revolut's Portuguese IBAN rollout is ongoing. Most expats pair a free local account with Wise for currency.
Is my money protected in a Portuguese bank?
Yes — the Fundo de Garantia de Depósitos covers up to €100,000 per depositor per bank. Wise safeguards client funds but, as a payment institution, has no deposit insurance.
