Navigate tax residency rules

Your tax residency status determines where you pay income and investment taxes. Rules vary by country but share common principles.

Determine residency status

• Physical presence test: you’re usually tax resident where you spend over six months a year
• Center of vital interests: if your family, home or job ties bind you to one country
• Statutory days count: keep a calendar of arrival and departure dates

Track your days carefully. Some EU states use a 183-day threshold, while others apply a rolling-year approach. If you split time equally, the “center of vital interests” test may tip the balance.

Understand double tax agreements

Double tax agreements (DTAs) prevent you from paying tax twice on the same income. Key points:

• Determine which country has primary taxing rights on dividends, interest and capital gains
• Identify treaty provisions on residency tie-breakers
• Claim tax credits or exemptions in your home country

Review the DTA between your home nation and host country on your finance ministry’s website. Proper filings under a DTA can reduce withholding tax and safeguard you from unexpected bills.

Understand withholding tax changes

Withholding taxes are taken at source on dividends, interest and some investment earnings. Changes at the EU level are making things simpler.

EU harmonisation overview

In May 2024, the Economic and Financial Affairs Council agreed to harmonise withholding tax across member states to boost cross-border investment and reduce double taxation [1]. Key takeaways:

• Standard withholding rates will apply across most EU jurisdictions
• Streamlined processes cut red tape for foreign investors
• Member states will share data to prevent tax avoidance

Upcoming digital tax certificates

Pending legislation will introduce common digital tax residence certificates. Once live, these electronic documents will:

• Replace paper forms when claiming treaty benefits
• Automate cross-border issuance and verification
• Reduce delays in dividend payments

Comply with reporting requirements

You must report foreign investments to local and home authorities. Failing to disclose assets can lead to stiff penalties.

US expat reporting

If you’re a US citizen or green card holder, you must file:

1. FBAR (FinCEN Form 114) for foreign accounts exceeding $10,000 aggregate
2. FATCA disclosures (Form 8938) if your foreign assets exceed thresholds
3. Annual tax return reporting worldwide income

American expats often find European banks reluctant to service them due to FATCA paperwork requirements [2]. Plan early to gather bank statements and hire an adviser familiar with both IRS and EU rules.

PFIC and Form 8621

Many EU mutual funds and ETFs are classed as Passive Foreign Investment Companies by the IRS. If you hold PFIC shares over $25,000 or receive distributions, you must file IRS Form 8621 every year [3]. Non-compliance can trigger punitive tax rates and interest.

CRS and local disclosures

Under the Common Reporting Standard, EU financial institutions send your account data to your tax residence country. You may also need to:

• Declare foreign assets on local tax returns
• File wealth tax or asset declarations, where applicable
• Submit additional schedules for rental properties or trusts

Check your host country’s tax portal for specific disclosure forms.

Manage investment product regulations

EU rules cover the sale and distribution of securities to expats. You must use compliant products and documentation.

MiFID II and PRIIPs KIDs

Since January 2018, MiFID II has required standardized Key Information Documents (KIDs) under PRIIPs for most packaged investment products [3]. You should:

• Request the PRIIPs KID before investing in funds, ETNs or structured notes
• Compare KIDs to assess costs, risks and performance scenarios
• Avoid products without an EU-compliant KID to stay within regulation

Local product eligibility

Different products have varying cross-border approval:

• Stocks and ETFs listed on EU exchanges are widely accessible
• Some EU funds are restricted to resident investors
• Specialist vehicles like UCITS funds offer passporting across member states

For ETF options suited to expats, see our expat-friendly investment etfs europe guide.

Mutual funds and PFICs

• Non-EU funds often lack PRIIPs KIDs and may be PFICs for US expats
• Check domicile and tax treatment before subscribing
• Consider EU-domiciled alternatives to reduce reporting burdens

Crypto rules

Regulation of digital assets is evolving:

• Some EU countries classify crypto as financial instruments under MiFID II
• Expect upcoming EU-wide rules on anti-money laundering and investor protection
• Report crypto gains as capital income; convert to euros at transaction dates

Plan for pension coordination

Your state pensions and private retirement plans need careful handling across borders.

EU pension aggregation

When you’ve worked in multiple EU countries, your pensions are calculated pro rata:

• Apply in your current country of residence or last work country
• Each authority computes a theoretical pension based on total EU contributions
• You receive payments from each country where you qualify [4]

Tax treatment of foreign pensions

• Some countries tax foreign pensions as regular income
• Others grant credits for taxes paid abroad under DTAs
• Check expat retirement plans europe for country-specific guidance

Retirement account reporting

For US expats, foreign pension plans may require annual disclosure on Form 8938 and 5471. Non-US expats should report employer pensions or private schemes under local rules.

Set up compliant banking solutions

Having the right bank accounts makes investing and daily finance smoother.

Local bank account benefits

Opening a host-country account typically:

• Reduces foreign transaction and conversion fees
• Provides access to local payment systems like iDEAL in the Netherlands [5]
• Builds local credit history for loans or mortgages

Keep your home country account open briefly to handle old transactions, then update your address to avoid closures.

US banking and Patriot Act

US banks require a verified residential US address for account holders, disallowing mail forwarding or PO boxes [6]. If you lose US banking access:

• Consider domicile services that provide bona fide US addresses
• Use expat-friendly banks with proven US compliance

Cross-border transfer rules

• Foreign banks report US expat accounts under FATCA (FBAR filings may apply)
• Large transfers can trigger anti-money laundering checks
• Compare fees on SWIFT, SEPA and specialist money transfer services

Navigate property investment rules

Real estate can be a cornerstone of your portfolio but comes with specific hurdles for expats.

Mortgage requirements for expats

• Higher deposit requirements, typically 20–30 percent
• Proof of foreign income, often embassy-certified documents
• Additional compliance checks post-Brexit for UK nationals [1]

Property taxes and reporting

• Annual property taxes vary by region
• Capital gains tax often applies on resale

Mitigate currency and transfer risks

Fluctuating exchange rates can turn profits into losses if unmanaged.

Reporting currency gains

• Report gains or losses from currency conversions as taxable events
• Use official exchange rates at transaction dates
• Keep detailed logs of each trade or property sale

Exchange controls and fees

• Non-euro EU members may impose limits on large cash purchases
• Compare conversion fees among banks, brokers and fintech providers
