Before You Start
- You own US-listed stocks (e.g., Apple, Microsoft) or US-domiciled ETFs that paid dividends in 2025.
- You are a tax resident in an EU country and must file a 2026 tax return.
- Your broker provides a tax statement or dividend summary for 2025.
- You have access to your EU tax authority's online filing system or compatible tax software.
- You are aware of your country's rules on foreign income reporting.
Time needed: 45–90 minutes
What you'll need: Broker account (e.g., DEGIRO, Trade Republic, Interactive Brokers), access to broker statements, calculator, online tax platform login, and (optionally) a EUR/USD conversion tool.
Declaring US stock dividends on your EU tax return can feel intimidating, but with the right process—and a few tested strategies—you can avoid double taxation and stay compliant. This step-by-step guide demystifies the process for 2026, using real EUR/USD examples and practical instructions for platforms like DEGIRO and Trade Republic. You’ll learn not just how to declare US dividends, but why each step matters—and what to do if things go wrong.
Step 1: Collect Your US Dividend Data
What to do: Download your 2025 dividend reports from your broker(s). For DEGIRO, go to Documents → Annual Report (Jahresbericht). For Trade Republic, tap Profile → Documents → Annual Tax Report.
- Identify all US dividends received in 2025, including stocks (e.g., Apple, Microsoft) and US-domiciled ETFs (e.g., iShares Core S&P 500 UCITS ETF).
- Note the gross dividend (before any tax), US withholding tax deducted, and the net amount paid to you.
- Record the USD amount and the date paid for each dividend.
Why it matters: EU tax authorities require you to declare worldwide income, and you must provide accurate figures. The gross dividend and US tax withheld determine your foreign tax credit and help you avoid double taxation.
What can go wrong: Brokers sometimes report only net dividends. If so, check the “withholding tax” column or contact support for a breakdown. Missing these details can mean overpaying tax.
Pro Tip
Keep all PDF statements and download them annually—brokers may restrict access after a few years.
Step 2: Convert USD Dividends to EUR
What to do: For each dividend, convert the USD amount to EUR using the official exchange rate on the payment date. Many EU tax authorities (e.g., Germany, France) accept the ECB reference rate or their own published annual average.
- Find the correct rate on the ECB website.
- For example, if you received a $100 dividend on 15 March 2025 and the EUR/USD rate was 1.10, your dividend is €90.91 (€100 / 1.10).
Why it matters: Declaring in EUR is a legal requirement. Using the wrong rate can trigger audits or penalties.
What can go wrong: Using today’s rate or your broker’s conversion (which may include hidden fees) instead of the official rate. Always stick to the rate your tax authority prefers.
Step 3: Understand US Withholding Tax and Double Taxation Agreements
What to do: Check how much US withholding tax was applied to your dividends. For most EU residents, this will be 15% if you submitted a W-8BEN form via your broker. Some brokers (e.g., DEGIRO, Interactive Brokers) allow you to do this online under Profile → Tax Forms.
- If you did not submit a W-8BEN, you may have paid 30%—double-check your broker’s report.
- Know your country’s double taxation agreement (DTA) with the US. Most EU countries allow you to claim a foreign tax credit for the 15% US tax withheld.
Why it matters: Avoiding double taxation is possible thanks to DTAs. You pay US tax at source, then declare the gross amount and claim a credit in your home country.
What can go wrong: If you skip the W-8BEN, you’ll pay 30% US tax and may need to reclaim the excess. See How to Reclaim Foreign Withholding Tax on Dividends—Step-by-Step for 2026 for details.
Pro Tip
Check your broker’s FAQ for W-8BEN renewal reminders—some (like Trade Republic) require periodic updates to keep the 15% rate.
Step 4: Input US Dividends in Your EU Tax Return
What to do: Log into your country’s online tax platform or use approved tax software (e.g., ELSTER for Germany, impots.gouv.fr for France, Tax-on-Web for Belgium).
- Locate the section for foreign investment income or dividends from abroad.
- Enter the total gross dividend in EUR.
- Enter the US tax withheld (as a foreign tax credit).
- Attach/upload your broker’s dividend statement if the platform allows (often optional, but recommended).
Why it matters: Correct reporting ensures you are taxed only on the amount above the US withholding, not the full gross again.
What can go wrong: Declaring only the net dividend (after US tax) can result in lost foreign tax credits. Always declare the gross and the withheld amount separately.
Pro Tip
Some platforms auto-fill domestic dividends but miss foreign ones. Always double-check and manually add US dividends if needed.
Step 5: Claim Any Excess Withholding—If Applicable
What to do: If the US withheld more than 15% (e.g., 30% due to missing W-8BEN), consider reclaiming the excess. This is done via IRS Form 1042-S and Form 1040NR, typically with your broker’s help.
- Request a 1042-S from your broker (e.g., Interactive Brokers provides this in March).
- File the claim directly with the IRS or use a reclaim service. See How to Reclaim Foreign Withholding Tax on Dividends—Step-by-Step for 2026 for details.
Why it matters: Recovering over-withheld tax can improve your net return by hundreds of euros over time.
What can go wrong: The reclaim process is slow (6–18 months) and paperwork-intensive. If the amount is small, weigh the effort versus benefit.
Step 6: Review and Submit Your Return
What to do: Double-check all entries—especially the conversion rates, gross amounts, and foreign tax credits. Use your tax platform’s summary view to confirm US dividends are listed and credits applied.
- Save a copy of your completed return and all supporting documents.
- Submit before your national deadline (often 31 May–30 June, but check locally).
Why it matters: Mistakes can lead to audits, penalties, or missed credits. A final review ensures your US dividend income is correctly declared and taxed only once.
What can go wrong: Rushing the process or missing a supporting document upload may trigger follow-up questions from the tax office.
Pro Tip
Set a recurring calendar reminder to download your annual broker statements every January—this will make next year’s declaration easier.
Common Mistakes
- Declaring only net dividends: Always declare the gross amount and withheld tax separately, or you’ll lose your foreign tax credit.
- Using the wrong EUR/USD exchange rate: Use the rate required by your tax authority, not your broker’s conversion.
- Missing W-8BEN form renewal: This can double your US withholding. Check with your broker annually.
- Not claiming a foreign tax credit: Failing to claim this means you’re taxed twice on the same dividend.
- Forgetting small US dividends: Even minor amounts should be declared to avoid compliance issues later.
