Living abroad creates unique financial challenges. Learn common mistakes expats make. Read more.
Germany's financial system was not designed with newcomers in mind. Between the language barrier, unfamiliar tax rules and the general opacity of pensions and investment products, it is genuinely easy to make costly mistakes in the first few years.
And those mistakes can take a long time to undo.
This article is not about selling you anything. It is about the mistakes we see most often when international families come to us – and how to avoid them.
This is by far the most common one. Many expat families arrive, focus on settling in, and leave substantial savings sitting in a Girokonto or Tagesgeld account for years.
That feels safe. But with inflation, money in a low-interest account quietly loses purchasing power every single year.
The problem is not saving. The problem is that the money is not working.
If you have a time horizon of ten years or more – and for a child's savings plan you almost always do – leaving everything in cash is a decision with a real cost, even if it does not feel like one.
This one is expensive, and it is the mistake we feel strongest about warning you against.
Many expats are sold long-term insurance or pension products in their first years in Germany – sometimes Riester, sometimes Rürup, sometimes a rigid company pension. These products can be reasonable for someone who will spend their whole working life in Germany.
For an internationally mobile family, they can be a trap.
The problems are structural: very long contract terms, high fees, and poor portability. Some products cannot be paid out as a lump sum at all. And with certain state-subsidised products, leaving the EEA can mean you have to repay the subsidies you received.
So before you sign anything long-term, ask three questions:
What happens to this contract if I leave Germany?
Can I keep contributing from abroad, or does it freeze?
What does it actually cost me over the full term?
If your adviser cannot answer these clearly, that is your answer.
This is precisely why we work with structures that stay workable if your life changes. A savings plan that punishes you for moving is not a savings plan. It is a liability.
Many families arrive and keep investing through the broker they used back home – or assume they can simply open one here.
Both assumptions can fail.
US citizens face a specific hurdle: because of FATCA reporting rules, many German brokers and neo-brokers will not accept US persons at all. This catches American families completely off guard, often after they have already moved.
And going the other way, keeping a home-country investment account while being tax resident in Germany can create reporting obligations you did not expect. Under the international exchange of information (CRS), accounts are reported automatically between countries. Not declaring them is not an option.
The fix is boring but effective: sort out where your money can legally and practically live before you need it to grow.
This one costs families real money, quietly, every year.
Children in Germany have their own tax allowances. Between the basic allowance (Grundfreibetrag), the saver's allowance (Sparerpauschbetrag) and the special expenses allowance, investment income of up to roughly 13,384 euros per year can remain tax-free for a child (2026 figures).
Most expat families have no idea this exists. And even those who do often never file the paperwork – the Freistellungsauftrag with the bank, and where relevant a Nichtveranlagungsbescheinigung (NV certificate) from the tax office.
The result: tax is deducted that never needed to be paid.
There is a catch worth knowing, though. Putting assets directly in your child's name means the money legally belongs to them – with full control passing to them at 18, and possible consequences for BAföG later. That trade-off deserves a proper conversation, not a quick decision.
We hear this constantly: "We will start investing once we know whether we are staying."
It is completely understandable. And it is usually the most expensive decision of all.
Here is the problem: expat families often say this for five, eight, ten years. Meanwhile the single biggest advantage in long-term investing – time – is being spent doing nothing.
For a child's savings plan, this matters enormously. A plan started at birth has roughly 18 years to compound. One started at age eight has ten. That difference is not small, and no clever product choice later will make up for it.
You do not need certainty about the next twenty years to start. You need a structure that survives uncertainty. Those are different things.
Should I invest in Germany if I might leave in a few years?
Often yes, but the structure matters more than the product. Choose something that can continue or be adapted if you move, rather than a contract that locks you in.
I am a US citizen. Can I invest in Germany at all?
It is more restricted, because many German brokers do not accept US persons under FATCA. Options exist, but you need to check the provider carefully and be aware of your US filing obligations.
Are German pension products a good idea for expats?
It depends entirely on how mobile you are. Products with long lock-ins, high fees and poor portability are a poor fit for internationally mobile families – and some state-subsidised products can require repayment of subsidies if you leave the EEA.
Can I use my child's tax allowances as a foreigner?
Yes. The allowances depend on your child's tax status in Germany, not on your nationality.
If there is one thread running through all of these mistakes, it is this: expat families are usually sold products, when what they actually need is a structure.
A product is a thing you buy. A structure is a decision about how your money is organised – who owns it, what happens when you move, when your child gets access, and what it costs you over twenty years.
Get the structure right, and the product almost chooses itself. Get it wrong, and no product will save you.
We are not a tax firm, and we will tell you honestly when you need a specialist Steuerberater. But we do help international families in Germany build a structure that still works if life changes. Because for expat families, it usually does.
