Before You Start
- Be the legal parent or guardian of the child you wish to invest for.
- Have access to valid identification documents for both yourself and your child (passport or national ID).
- Check your country’s rules on junior accounts, as requirements and tax treatment vary.
- Have a European bank account for funding and withdrawals.
- Decide if you want to manage the investments yourself or automate with savings plans.
Time needed: 1–2 hours (setup), then 15 minutes/month (maintenance)
What you'll need: Valid IDs, proof of address, internet access, access to chosen broker/bank
Setting your child up for financial success starts early—and a junior investment account is one of the most effective ways to do it. In this step-by-step guide, you’ll learn exactly how to open, fund, and optimise a junior investment account in Europe, using real platforms like DEGIRO, Trade Republic, and major banks. We’ll cover legal and tax rules in key European countries, platform choices, funding methods, investment strategies (ETFs vs. stocks), and how to transfer the account to your child at adulthood.

Step 1: Understand What a Junior Investment Account Is (and Why It Matters)
A junior investment account (sometimes called a “child account” or “custodial account”) is a brokerage or bank account opened in the name of a minor, managed by a parent or guardian until the child reaches legal adulthood (typically 18, sometimes 21).
- Why this matters: Investing early—even with small amounts—lets your child benefit from compounding growth over many years. For example, investing €1,000 when your child is born and adding €50/month at 6% annual return could grow to over €20,000 by age 18.
- What can go wrong: If you use a regular account in your own name, tax benefits and legal ownership may be lost. In some countries, improper setup can cause gift tax issues.
Step 2: Compare Junior Account Options Available in Europe
Not all brokers or banks offer junior accounts—especially pan-European fintechs. Here’s what you need to know:
Major European Brokers

- Trade Republic: As of 2026, does not offer junior accounts—only adult accounts. (You can use a family account or consider alternatives.)
- Flatex: Available in Germany and Austria, supports junior accounts with stock and ETF access.
- National/Traditional Banks: Most major banks in France, Germany, Spain, and Italy offer junior investment accounts, but often with higher fees and limited investment options.
What to Look For
