How to Switch Brokers in Europe Without Triggering Big Tax Bills or Losses

Switching brokers in Europe can be daunting—especially if you want to avoid unnecessary tax events or losses on your investments. Whether you’re moving from DEGIRO to Interactive Brokers, or from Trade Republic to Scalable Capital, the process requires careful planning. In this guide, you’ll learn how to switch brokers in Europe with minimal tax impact, avoid forced sales, and keep your investment journey smooth.

As we covered in our complete guide to choosing a European stock broker, picking the right platform is only the first step—transferring your assets safely is just as important. Here, we’ll go deeper into the practical steps, tax pitfalls, and documentation you’ll need.

Step 1: Decide Whether to Transfer In-Kind or Sell and Reinvest

What to do: Choose between an “in-kind” (portfolio transfer) and a “sell-and-transfer-cash” approach.

• In-kind transfer: Your stocks/ETFs move from Broker A to Broker B without being sold.
• Sell-and-transfer-cash: You sell your positions, move the cash, and repurchase in your new account.

Why it matters: In-kind transfers usually do not trigger capital gains taxes, as you’re not selling your holdings—just moving them. Selling and rebuying, however, does trigger a taxable event in most European countries, even if you immediately reinvest.

What can go wrong: Not all brokers support in-kind transfers, or only for certain securities (e.g., some may not support US-listed ETFs or fractional shares). If your current broker only allows cash withdrawals, you’ll be forced to sell and may face a tax bill.

Step 2: Verify Supported Securities and Transfer Fees

What to do: Make a list of all your holdings. Check which ones are eligible for transfer to your new broker, and calculate any fees for transferring out or in.

• Some brokers (like DEGIRO) charge €10–€100 per ISIN for outgoing transfers.
• Receiving brokers (like Interactive Brokers) rarely charge incoming fees, but always check their fee schedule.
• Check if your new broker supports all your investments (e.g. some platforms do not accept OTC, US, or certain non-EU ETFs).

Why it matters: If a security isn’t supported, you may be forced to sell it, potentially triggering taxes or incurring losses. High transfer fees can eat into your returns, especially for small positions.

What can go wrong: Ignoring eligibility can result in partial transfers, stuck assets, or even lost tax records.

Step 3: Gather Documentation and Record Your Cost Basis

What to do: Download your full transaction history, annual tax statements, and current portfolio summary from your old broker.

• Save purchase dates/prices (“cost basis”) for each holding.
• Note any dividend reinvestments or corporate actions.
• Get your official transfer-out statement (often needed by the new broker).

Why it matters: Cost basis is not always transferred automatically between brokers, especially across borders. Without it, you may pay more tax later, as your new broker may assume a cost basis of €0.

What can go wrong: Failing to document your original purchase prices can create headaches (or tax overpayments) down the road, especially in countries like Germany, France, or Spain where self-reporting is required.

Step 4: Initiate the Transfer With Both Brokers

What to do: Start the transfer process. This usually means:

1. Log in to your new broker and fill out the “Incoming Transfer” or “Asset Transfer” form. Provide details about your current broker, account number, and list of ISINs.
2. Notify your old broker, often by submitting their transfer-out form or emailing support.
3. Attach any required supporting documents (ID, portfolio statement, etc.).

Why it matters: Both brokers need to coordinate. Missing or mismatched details (e.g., name or account number typos) are the #1 cause of failed or delayed transfers.

What can go wrong: International transfers (e.g., from a Dutch to a German broker) can take 2–8 weeks. Some brokers freeze your assets during the move, so you can’t trade. Transfers can fail if ISINs don’t match exactly, or if you have open orders or unsettled trades.

Step 5: Monitor the Transfer and Confirm Receipt

What to do: Log in to both brokers regularly. Track the status of each ISIN. Once the transfer is complete, check that all positions and quantities match your records.

• Check your new broker’s “Portfolio” or “Positions” tab for arrivals.
• Compare the number of shares/units and ISINs with your original list.
• Contact support immediately if anything is missing or incorrect.

Why it matters: Errors can occur (e.g., incomplete transfers, missing cost basis, or lost fractional shares). Early detection is key to fixing issues before the next tax year or dividend payment.

What can go wrong: If you miss a mistake now, it can be much harder to correct later, especially across jurisdictions.

Step 6: Update Your Tax Records and Notify Authorities if Required

What to do: Record the transfer in your personal tax records. In some countries (e.g., France, Spain), you may need to inform your tax office of a change in broker, especially if moving assets abroad.

• Check if your new broker provides annual tax reports in your language and format.
• Update your “cost basis” records, especially if not carried over automatically.
• Keep documentation for at least five years (standard in most EU countries).

Why it matters: Ensures you can prove your cost basis and avoid double taxation or fines. Some countries (like Germany) have strict rules about reporting foreign accounts.

What can go wrong: Failing to report new foreign accounts can result in penalties. Not updating cost basis can lead to overpaying capital gains tax when you eventually sell.

EUR Case Study: Moving €25,000 in ETFs from DEGIRO to Interactive Brokers

Let’s look at a realistic example for a German resident:

• Portfolio: €15,000 in iShares Core MSCI World UCITS ETF (IE00B4L5Y983), €10,000 in Xtrackers MSCI Emerging Markets (IE00BTJRMP35)
• Transfer type: In-kind (no selling)
• Old broker: DEGIRO
• New broker: Interactive Brokers (IBKR Europe S.A.)

1. Download your DEGIRO annual statement and transaction history. Confirm both ETFs are supported by IBKR.
2. IBKR: Go to “Transfer & Pay → Transfer Positions → Incoming” and select “DEGIRO” as the delivering broker. Enter your DEGIRO account details and list the two ISINs.
3. DEGIRO: Fill out and submit the “Securities Transfer” form as instructed by DEGIRO’s help center. Attach your IBKR account details.
4. Wait 2–4 weeks for the transfer. DEGIRO charges €10 per ISIN (€20 total).
5. Once complete, check your IBKR portfolio. Both ETFs should appear, with the same number of units. If cost basis is missing, manually record your purchase prices from DEGIRO’s statement.
6. Update your German tax records. No capital gains tax is due, as nothing was sold.

Expected outcome: You keep your positions, avoid triggering a taxable event, and now manage your portfolio at IBKR. You paid only the transfer-out fee (€20) and spent time updating your records.

Post-Transfer Checklist

• All positions and quantities match your original holdings
• Cost basis (purchase price) is documented for each security
• Dividends or pending corporate actions are accounted for
• Old broker account is empty and can be closed if desired
• Tax records are updated and compliant with your country’s rules

Key Differences Across Major EU Countries

• Germany: Brokers often handle tax withholding automatically. Self-reporting cost basis is vital if moving to a foreign broker.
• France: You must declare foreign accounts and may need to file extra forms (Formulaire 3916).
• Netherlands: Box 3 tax applies to your total assets; transfers rarely change your tax bill, but keep full records.
• Spain: Strict reporting of foreign accounts (Modelo 720) is required, with severe penalties for omission.
• Italy: Both brokers and investors report to the tax office; check with your commercialista for specifics.

Common Mistakes When Switching Brokers in Europe

• Assuming all brokers support in-kind transfers—always check first
• Failing to document your original cost basis for tax purposes
• Overlooking transfer-out fees and supported ISINs, causing partial or failed transfers
• Ignoring country-specific reporting requirements for foreign accounts
• Not double-checking received positions and missing errors in time
