Investments for Kids: Junior Accounts vs. Savings Plans

Most parents assume that opening a savings account for their child is a straightforward act of responsibility. But the structure behind that decision (who legally owns the assets, when taxes apply, and what happens when the child turns 18) can quietly shape outcomes worth tens of thousands of pounds. Investments for kids involve more moving parts than a simple account comparison suggests.

Germany’s financial landscape offers several routes for parents building long-term wealth on behalf of their children. Each carries distinct legal, tax, and control implications that most product-focused comparisons never address properly.

The real decision is structural: a child investment account opened in the child’s name operates under fundamentally different rules than a savings plan held by the parent. Knowing the difference before committing to a strategy is what separates a solid plan from a costly oversight.

The Two Core Structures for Child Investments in Germany

Before comparing platforms, parents need to understand the two main structural approaches available in Germany. The choice between them affects tax exposure, control, and long-term flexibility far more than the choice of ETF ever will.

The Kinderdepot: Investing in the Child’s Name

A Kinderdepot is an investment account opened in the child’s name, managed by parents until the child reaches adulthood. Banks and online brokers across Germany offer these accounts, and they can hold ETFs, stocks, and mutual funds.

The key legal reality is that the assets belong to the child from day one. Parents act as custodians, not owners. Once the child turns 18, they gain unrestricted access. The parent has no further say over how the money is used, regardless of the size of the sum or the circumstances.

From a tax perspective, the structure does offer advantages. Children in Germany benefit from an annual tax-free income threshold of over €13,000, which means capital gains up to that level are not taxed. For families making modest monthly contributions, this allowance effectively eliminates capital gains tax for many years.

The Parent-Held ETF Solution: Keeping Control in Your Hands

An alternative approach involves the parent remaining the account holder or policyholder, with the child named as a beneficiary. The investment strategy can be identical (diversified ETF portfolios, regular contributions), but the ownership structure is entirely different.

Consequently, the parent decides when and how to transfer ownership, which can be scheduled strategically around the child’s readiness, their tax situation, or key life events. This structure can also offer specific tax advantages upon transfer that are unavailable with a standard brokerage account.

The trade-off is a degree of administrative complexity and, in some cases, slightly higher ongoing costs depending on the product used.

The Hidden Variable Most Parents Miss: Student Financial Aid

Here is where the standard comparison articles fall short. In Germany, eligibility for BAföG student financial aid, which can be worth close to €10,000 per year for up to five years, depends partly on the assets held in the student’s name.

If a Kinderdepot grows beyond approximately €15,000, the child may become ineligible for BAföG support entirely. For families with lower to moderate incomes, this is not a theoretical concern. It is a concrete financial impact that can exceed the total investment gains by a significant margin.

Therefore, parents who plan to support a child through university in Germany should factor this threshold into their strategy well before the child reaches secondary school age. A parent-held savings structure sidesteps this issue, since the assets are not recorded as the child’s own until ownership is formally transferred.

Platform Options: What the Market Currently Offers

The German market has evolved quickly, and several platforms now offer competitive child savings products. The differences matter, but they should be evaluated only after the structural decision is made.

The following table outlines the current leading options and their core features:

Platform	Account Type	Key Feature	Notable Benefit
Trade Republic	Child Savings Account (Kinderdepot)	Zero fund fees on selected Vanguard ETFs until age 18	Savings Patrons feature for family contributions
Scalable Capital	Kids’ Account (Kinderdepot)	TER reinvested as Pocket Money; 0% Wealth management fee	2.50% interest p.a. on uninvested cash
Pensionfriend	Kids ETF Savings Plan (parent-held)	Parent retains ownership; child is beneficiary	BAföG-neutral; tax-efficient transfer options
Invest4Kids	Advisory-led ETF solutions	Personalised strategy for each family	Expert guidance on structure, not just products

Trade Republic’s recently launched Child Savings Account introduced what it calls the world’s first zero-fee ETF structure for minors. Fund costs on selected Vanguard products are refunded monthly and reinvested automatically until the child turns 18.

Additionally, the platform supports a “Savings Patrons” model, allowing family members to contribute via direct debit, a practical feature for grandparents or extended family who want to participate.

Scalable Capital offers a comparable model under its Pocket Money feature, where the product cost (TER) is reinvested back into the child’s ETF rather than charged as an ongoing fee. Over an 18-year period, even a modest TER saving compounds into a meaningful additional sum.

Running the Numbers: Why Starting Early Is Non-Negotiable

The mathematics of compound growth are unambiguous. A parent investing €100 per month from birth, with an average annual return of 7%, would accumulate over €43,000 by the child’s 18th birthday. If those funds remain invested through to retirement without additional contributions, the portfolio could exceed €1,000,000, driven entirely by time in the market.

However, these projections assume the structural decisions are sound. Taxes applied repeatedly over 18 years, or a lump sum handed to an unprepared 18-year-old, can erode both the financial and educational value of the investment. The figures are compelling, but they only hold if the vehicle behind them is built correctly.

For parents who want to model different contribution levels and timelines, Pensionfriend’s children’s savings calculator provides a useful planning tool, allowing families to input monthly amounts and target ages to see projected outcomes under realistic return scenarios.

The Decision Framework: Four Questions Before You Open Anything

Rather than defaulting to the most-advertised product, parents benefit from working through a short set of structural questions first. The answers will determine which vehicle is actually appropriate for their situation.

• Will the child study in Germany? If yes, the BAföG threshold is a critical constraint, so a parent-held structure may be significantly more valuable than a Kinderdepot.
• How much do you plan to invest over 18 years? Smaller amounts (under €15,000 total) are less structurally sensitive; larger amounts demand more careful planning around tax and control.
• Do you want to retain control beyond age 18? If yes, a Kinderdepot is the wrong structure by design, as ownership transfers automatically and irrevocably.
• Is this a family effort or a parental one? Platforms with features for family contributions, like savings patrons, add real practical value when grandparents or relatives want to participate consistently.

For families who want expert guidance through this process rather than navigating it alone, Invest4Kids offers personalised advisory consultations specifically designed for parents building ETF strategies for their children, with over 5,200 families already supported through the service.

Tax Considerations Worth Planning Around

Germany’s tax system offers significant advantages for child investments, but only if they are used deliberately.

Children can use the standard tax-free income threshold (Grundfreibetrag), the saver’s allowance (Sparer-Pauschbetrag), and other deductions. This means capital gains up to a combined threshold of over €13,000 per year can be realised tax-free.

Additionally, Germany’s gift tax rules allow parents to transfer up to €400,000 per child every ten years without triggering gift tax. Grandparents can transfer up to €200,000 per grandchild under the same rules, with these thresholds reset every decade, which means thoughtful timing of ownership transfers can legally eliminate a significant portion of the tax liability.

The critical difference between structures is this: with a Kinderdepot, capital gains tax applies whenever investments are sold or rebalanced. With a parent-held ETF policy, certain restructuring can occur without triggering an immediate tax event, a practical advantage over a multi-decade investment horizon.

What the New Government Initiative Changes

Germany’s coalition agreement introduced the concept of a ‘Frühstart-Rente‘, a government contribution of €10 per month for children from the age of six. It is designed to introduce younger generations to capital markets and begin building private retirement savings early.

Platforms such as Trade Republic have already structured their child accounts to be compatible with this incoming benefit, and while €10 per month in isolation is modest, the principle it establishes matters: the state is acknowledging that public pension provision alone will not be sufficient for the next generation.

Parents who have already built a structured savings plan will be positioned to integrate this government contribution seamlessly, rather than starting from scratch when the policy becomes active.

Building Wealth That Actually Reaches Its Purpose

Thinking about investments for kids as a structural decision, not just a product selection, is what separates families who end up with a clear, tax-efficient outcome from those who discover costly surprises at the age of 18 or 21.

Starting early matters enormously, but starting correctly matters just as much. A well-chosen ETF inside the wrong ownership structure can underperform a slightly less optimal ETF inside the right one, purely because of how taxes and control rules interact over two decades.

The families who get this right are not necessarily the wealthiest or the most financially sophisticated. They are simply the ones who asked the right questions before making the first deposit.
