Banking and Brokerage Setup Checklist

Step-by-step guide to opening bank accounts and brokerage accounts as a new European resident — the documents you need, the banks that work, and the mistakes to avoid.

Before You Arrive: Preparation Is Everything

Opening a bank account in Europe as a new resident from Latin America, the Middle East, or Asia should be straightforward. In practice, it is one of the most frustrating parts of relocation — primarily because banks have become extremely cautious about onboarding non-EU nationals since the implementation of stricter anti-money-laundering (AML) regulations.

The difference between a 2-day account opening and a 2-month ordeal comes down to preparation. This guide covers exactly what you need.

Required Documents (Universal)

Regardless of which European country you are settling in, every bank will require:

1. Valid passport — must have at least 12 months of validity remaining. Some banks will also accept a national ID card from EU countries.

2. Proof of residency — this creates a chicken-and-egg problem: you need a bank account to rent an apartment, but you need a rental contract to open a bank account. Solutions:

• A hotel booking or temporary accommodation contract is accepted by most banks for initial account opening
• An empadronamiento (Spain) or equivalent municipal registration is the gold standard
• A letter from your employer confirming your relocation is often sufficient

3. Tax identification number — in Spain this is the NIE (Número de Identidad de Extranjero), in Portugal the NIF (Número de Identificação Fiscal), in Estonia the isikukood. You can usually apply for this before arriving or within the first days.

4. Source of funds documentation — this is where most delays occur. Banks are required to understand where your money comes from. Be prepared to provide:

• Employment contracts or company ownership documents
• Tax returns from your home country (2-3 years)
• Property sale documents if relevant
• Investment account statements
• Company financial statements if you are a business owner

5. Proof of economic activity — employment contract, business registration, or evidence of pension/investment income.

Country-Specific Banking Setup

Spain

Recommended banks for new residents:

• Sabadell — generally the most accommodating with LATAM clients. English-speaking staff available in Barcelona and Madrid. International desk handles complex onboarding.
• CaixaBank — Spain's largest bank, with excellent digital banking infrastructure. The international private banking division handles HNW clients smoothly.
• BBVA — strong ties to Latin America through its Mexican subsidiary, which can facilitate asset transfers.
• Openbank (Santander digital subsidiary) — fully digital onboarding, often faster than traditional branches.

Timeline: Expect 1-3 weeks from first visit to fully functional account. HNW clients with private banking relationships can often expedite to 3-5 days.

Common obstacle: The "informar sobre la titularidad real" requirement — beneficial ownership declaration for any accounts linked to foreign companies. Bring your company's shareholder registry and articles of incorporation, apostilled and translated.

Portugal

Recommended banks:

• Millennium BCP — Portugal's largest private bank, with specific programs for international clients
• Novo Banco — competitive pricing, strong digital platform
• ActivoBank — digital-first option with lower fees

Unique requirement: Portugal requires a NIF (tax number) before any bank will open an account. Non-residents can obtain a NIF through a fiscal representative — a Portuguese tax resident who agrees to serve as your point of contact with the tax authority. Budget €150-300 for this service.

Estonia

Recommended banks:

• LHV Pank — Estonia's largest domestic bank, excellent for both personal and business accounts. Digital onboarding available for e-Residents.
• Swedbank Estonia — major Nordic bank with strong local presence
• Wise (TransferWise) Business — not a bank, but offers multi-currency accounts with Estonian IBANs. Fastest setup for international transfers.

Advantage: Estonia's digital infrastructure means account opening can be completed online in many cases, with video identification replacing in-person visits.

Brokerage Account Setup

Your investment accounts need to be restructured when you change tax residency. This is not optional — most US and LATAM brokerages either restrict or close accounts held by European tax residents.

Recommended platforms for European residents:

Interactive Brokers (IBKR) — the gold standard for serious investors. Supports virtually all global markets, competitive pricing, excellent tax reporting for European jurisdictions. The Ireland-based entity (IBKR Ireland) serves EU clients. Minimum to open: $0 (no minimum for individual accounts).

Saxo Bank — Danish-regulated platform with strong coverage of European and Nordic markets. Better user interface than IBKR but higher fees. Good for clients who want a more polished experience.

DeGiro — Dutch platform owned by flatexDEGIRO AG. Lowest fees in Europe for standard ETF and stock trading. Limited product range compared to IBKR but perfectly adequate for long-term investors using ETFs and equities.

Swissquote — Swiss-regulated, recommended for clients who want Swiss custody for a portion of their assets. Higher fees, but banking secrecy and stability are the value proposition.

Key considerations when choosing:

• Tax reporting compatibility: Your broker must provide reports compatible with your tax residence country's filing requirements. In Spain, this means Modelo 720 (foreign assets declaration) reporting. IBKR and Saxo handle this well.
• Withholding tax treaties: Ensure your broker correctly applies reduced withholding rates under applicable tax treaties. A US equity held through an Irish-based broker should face 15% US withholding (under the Ireland-US treaty), not the default 30%.
• Currency management: Multi-currency accounts allow you to hold positions in different currencies without constant FX conversion.
• Regulatory protection: EU-based brokers are covered by investor compensation schemes (up to €20,000 in most countries). IBKR Ireland provides this plus additional commercial insurance.

The Transfer Process

Moving existing positions from a LATAM or US broker to a European platform:

1. In-kind transfer (ACAT or equivalent): The preferred method. Your positions transfer without being sold, preserving your cost basis and avoiding capital gains tax. Not all brokerages support cross-border in-kind transfers — confirm with both sending and receiving brokers before initiating.

1. Liquidate and re-purchase: If in-kind transfer is not available, you may need to sell positions at the old broker and re-purchase at the new one. This triggers capital gains tax in your current jurisdiction — timing this before your tax residency changes can be advantageous.

1. Timeline: In-kind transfers typically take 1-4 weeks. International transfers may take longer due to additional compliance checks.

Common Mistakes

1. Not closing US accounts promptly. US brokers may freeze accounts when they learn you have become a European tax resident. Proactively transfer or liquidate before this happens.

1. Ignoring Modelo 720 (Spain). Spanish tax residents must declare all foreign accounts and assets above €50,000 annually. Non-compliance penalties used to be draconian (150% of undeclared value); while the EU struck down the most extreme penalties, filing remains mandatory.

1. Using personal accounts for business. Keep personal and business banking strictly separate from day one. Mixing them creates accounting nightmares and can trigger AML flags.

1. Choosing a bank based on proximity. In 2025, the quality of a bank's digital platform matters more than how close the branch is to your apartment. Prioritize digital banking capability, international wire processing speed, and multi-currency support.
