What you'll need: Internet access, your portfolio/account logins, and (optionally) spreadsheet software for scenario planning
Wealth tax is a hot topic in Europe. Multiple EU countries are tightening, or reintroducing, wealth tax regimes for 2026—sometimes with lower thresholds, new asset classes added, and stricter reporting. Whether you’re a resident or an expat, optimising your EUR portfolio for wealth tax is crucial to protecting your returns.
This guide provides a detailed, step-by-step approach with actionable EUR examples. We’ll cover taxable vs. non-taxable wrappers, cross-border structuring, and the smart use of ETFs and cash equivalents—so you can reduce the impact of both current and anticipated European reforms. For a broader context on what’s changing across the EU, see our Ultimate Guide to EU Wealth Taxation for Expat Investors in 2026.
Step 1: Map Your Current Portfolio to Tax Status
What to do: Make a list of all your EUR-denominated assets. For each holding, record:
- Type (e.g., ETF, stocks, bonds, cash, real estate)
- Account type (standard brokerage, pension, life insurance wrapper, etc.)
- Country of account/brokerage
- Current market value (in EUR as of today)
Example:
- €60,000 in iShares Core MSCI World UCITS ETF (IWDA, IE00B4L5Y983) in Trade Republic (Germany, standard account)
- €30,000 in cash in N26 (Germany)
- €15,000 in Amundi MSCI Europe UCITS ETF (C6E, LU1681042605) in DEGIRO (Netherlands, standard account)
- €40,000 in a French Assurance Vie (life insurance) wrapper, invested in euro-denominated funds
Why it matters: Wealth tax is usually assessed on your net worth above a certain threshold, but not all account types are treated equally. Some wrappers (like pensions or life insurance) may be partially or fully exempt, depending on your residency and local law.
What can go wrong: Overlooking assets held abroad or in less obvious wrappers (like crypto or collectibles) can lead to underreporting and penalties. For crypto, see our Crypto Taxation in Europe: 2026 Cheat Sheet for HODLers and Active Traders.
Pro Tip
Use a spreadsheet to track your total portfolio by both account type and country. Colour-code taxable vs. non-taxable accounts for quick visual checks.
Step 2: Identify Taxable vs. Non-Taxable Wrappers
What to do: For each account, check if it’s a taxable or non-taxable wrapper under your country’s 2026 rules. Common wrappers:
- Pension accounts (e.g., German Riester/Rürup, French PER, Dutch pensioenrekening): Usually not included in wealth tax until withdrawal
- Life insurance wrappers (Assurance Vie in France, Lebensversicherung in Germany): Often enjoy partial or full exemptions
- Standard brokerage accounts (Trade Republic, DEGIRO, Interactive Brokers EU): Fully taxable for wealth tax purposes
- Cash holdings: Fully taxable above exemption thresholds
Why it matters: Shifting assets into non-taxable wrappers can legally reduce your annual wealth tax base. For example, moving €40,000 from a standard account to an Assurance Vie could save €400 per year at a 1% wealth tax rate.
What can go wrong: Some wrappers have restrictions (e.g., minimum lock-in periods, early withdrawal penalties, or limited investment options). Always check official documentation before transferring funds:
Pro Tip
In France, you can open multiple Assurance Vie contracts with different insurers to diversify and maximise tax benefits. In Germany, consider splitting contributions between Riester and Rürup for flexibility.
Step 3: Rebalance Towards Tax-Efficient ETFs and Cash Equivalents
What to do: Within your taxable accounts, prefer EUR-denominated ETFs that are domiciled in Ireland or Luxembourg, as these often have lower withholding taxes and reporting burdens. For cash, consider money market ETFs or fixed-term deposits in wrappers where possible.
Example:
- Sell €10,000 of individual German stocks in Trade Republic
- Buy €10,000 of Vanguard FTSE All-World UCITS ETF (VWRL, IE00B3RBWM25) domiciled in Ireland
- In DEGIRO, set up an automatic investment plan: Portfolio → Recurring Investments → Select “iShares Core MSCI World UCITS ETF (IWDA, IE00B4L5Y983)” → Amount: €500/month
- For cash, transfer €5,000 to a flexible EUR money market ETF, e.g., Amundi Prime Euro Corporates UCITS ETF (PRIC, LU1931974429)
Why it matters: Broad, tax-efficient ETFs are easier to report and less likely to attract scrutiny, especially when reforms limit deductions for direct stocks or high-yield savings. Money market ETFs may offer higher returns than cash, with similar liquidity.
What can go wrong: Some ETFs are ineligible for wrappers or local tax relief. Always check the ISIN and domicile before buying. Also, double-check if your platform supports auto-investing in these ETFs.
Pro Tip
Platforms like Trade Republic and DEGIRO offer commission-free ETF savings plans for many EUR-denominated UCITS ETFs.
Step 4: Consider Cross-Border Structuring (Legally)
What to do: If you have or expect cross-border ties (e.g., moving, retiring, or working in another EU country), research tax treaties and the treatment of your wrappers in both countries. For example, a French Assurance Vie may be partially exempt in France but fully taxable if you move to Spain.
Actions:
- Check the tax treatment of your wrappers in your current and potential future country
- If holding assets in another EU country, ensure you are compliant with both local and home country reporting
- Review double-tax treaties (see our How to Avoid Double Taxation as a European Expat Investor: 2026 Step-by-Step)
Why it matters: The EU is harmonising certain tax rules, but differences remain. Mistakes can result in double taxation or missed exemptions.
What can go wrong: Some countries (e.g., Spain, Norway) are aggressive in taxing foreign-held assets. Failure to declare can result in high fines and even criminal penalties.
Pro Tip
Keep all documentation for cross-border holdings in both digital and paper form. Many countries require detailed “foreign asset” declarations, and the rules change frequently.
Step 5: Use Annual Rebalancing to Stay Below Thresholds
What to do: Each year, review your total taxable wealth. If you’re near the threshold (e.g., €1 million in France, €700,000 in Spain), consider:
- Gifting assets to family members (within exemption limits)
- Contributing more to tax-sheltered wrappers
- Spending down cash or using lump sums for strategic investments (e.g., energy-efficient home improvements, which may be exempt)
Example: If your taxable portfolio is €995,000 and the threshold is €1,000,000, investing €10,000 more into a pension wrapper can keep you below the limit and avoid annual wealth tax entirely.
Why it matters: Wealth tax is typically assessed as of 31 December. A small adjustment before year-end can make a significant difference for the following tax year.
What can go wrong: Mistiming contributions or withdrawals can push you over the threshold. Some wrappers have year-end cutoffs for deposits to count for that tax year—check with your provider.
Pro Tip
Set a calendar reminder for early December each year to review your wealth tax position and make any last-minute adjustments before the cut-off date.
Step 6: Stay Informed on 2026 Wealth Tax Reforms
What to do: Monitor official government and tax authority updates in your country, as well as trusted financial news sources. Many reforms are still being finalised for 2026, with details on thresholds, exemptions, and reporting requirements subject to change.
- Subscribe to your national tax authority’s newsletter
- Bookmark and periodically check the Ultimate Guide to EU Wealth Taxation for Expat Investors in 2026
- Consider robo-advisors that automatically rebalance for tax efficiency (see PILLAR: The Ultimate 2026 Guide to Robo-Advisors for European Investors—Automate Your Portfolio in EUR)
Why it matters: Tax law changes can be rapid and retroactive. Early awareness lets you adapt before deadlines hit.
What can go wrong: Relying on outdated information can result in missed exemptions, penalties, or overpaying tax.
Pro Tip
Join online forums or local investor groups focused on your country’s wealth tax changes—peer discussions often surface practical tips not yet covered in official guides.
Common Mistakes in EUR Wealth Tax Optimisation
- Assuming all wrappers are exempt: Rules vary by country and wrapper type.
- Forgetting about foreign-held assets: Most EU countries require global asset reporting for residents.
- Neglecting annual review: Portfolio values and tax laws change—optimisation is an ongoing process.
- Using ineligible ETFs: Some non-UCITS or US-domiciled ETFs are not tax-efficient for EU residents.
- Missing platform cut-offs: Some brokers require transfers or purchases by a certain date for year-end reporting.
Next Steps
- Review your portfolio structure and identify accounts/assets that need rebalancing
- Explore local tax wrappers and consider shifting assets for greater tax efficiency (see our Best Tax-Optimised EUR Investment Accounts for European Residents in 2026)
- Stay up to date with wealth tax rules and adjust your strategy annually
- Diversify across wrappers and jurisdictions, but always comply with reporting rules
