A Bank Account for a Child: From Piggy Bank to Card

Let me tell you something I understand as a father better than many an interest rate: a child learns about money from you long before they ever touch their first card. At the checkout they watch whether money is a calm subject at home or a source of tension. And from those observations they build their attitude to every złoty long before anyone thinks about an account.

A bank account for a child is a good tool. But it’s only the last stage of a longer journey — from a physical piggy bank, through pocket money, to a card with limits. In this article we’ll walk that path step by step: when to introduce what, on what terms, and what the law takes care of for you.

First a piggy bank, not an app

Let’s start with something concrete, because financial education likes to begin with theory when it should begin with a coin in the hand. An adult understands an entry on an account. A small child understands a banknote, a coin and a transparent jar where you can see the money growing or shrinking. It sounds trivial, but this is exactly the level at which financial intuition is formed.

That’s why, at the start, a transparent piggy bank works better than a classic, closed one. The child sees the effect of their decisions right away: added some — it grew, took some out — it shrank. No banking app will show that to a six-year-old half as vividly.

A tried-and-tested trick is splitting money into three containers. It’s a simple ritual: the child gets some money, divides it into parts and sees that every złoty can have a different job.

Container	Purpose	What it teaches
„I spend”	Small treats	Decisions and consequences
„I save”	A bigger goal	Patience and planning
„I help / gift”	A gift, a collection, helping	Sharing and the intent behind spending

It’s not about building a household bank. It’s about the child physically feeling that money can be split across different purposes. The rest — an account, a card, BLIK (Poland’s mobile payment system) — will come later and will just be a digital version of the same principle.

Pocket money: from what age and on what terms

It’s worth introducing pocket money once the child grasps a simple relationship: „I have a set amount and I decide for myself what to do with it”. For one child that’s 6–7 years old, for another a bit later. There’s no point forcing the age.

And here’s a point that surprises many parents: the most important thing isn’t how much to give. The most important thing is the rules. Good pocket money sticks to a few rules that work regardless of the amount.

• Regular. A small amount every week beats random transfers „whenever it comes to mind”. Regularity teaches planning.
• Predictable. The child should know when and how much they’ll get.
• Not for every household chore. Helping at home isn’t a paid service — the child is part of the family. You can pay for extra, above-and-beyond tasks.
• Not as the main punishment tool. If money is constantly taken away over behavior, the child learns that it’s a tool of control, not of management.
• With the right to make mistakes. If they spend it all on the first day, don’t rush to the rescue. A calm „I understand, but the next one comes on Friday” is one of the cheapest financial lessons in life.

As for the amount — there’s no single right one. It depends on age, where you live, the family’s situation and on what the child is supposed to cover with that money. A simple rule applies: the younger the child, the smaller the amount and the shorter the period. For younger children weekly pocket money works better, because a month is too distant a horizon for them. For a teenager, monthly — because it resembles an adult budget.

Age	Rhythm	What for
6–8 years	weekly	small choices, a piggy bank, first saving
9–12 years	weekly or every two weeks	planning small expenses
13–15 years	monthly or partly weekly	learning budgeting, a card, an account, limits
16–18 years	monthly	greater independence, transport, going out, saving

The amount should be felt enough that something can be planned, but not so high that every whim is available on the spot. A little tension between „I want” and „I have” isn’t a bug in the system — it’s the point of it.

Needs, wants and goals — three words to introduce early

One of the most important lessons is being able to name what you’re actually doing with money. Three words are enough. A need is something necessary or very important: food, clothing, school, health. A want is something pleasant but not necessary: another toy, a skin in a game, a branded gadget. A goal is something we consciously set money aside for: a bike, a console, a trip, a gift.

It’s not about shaming the child for wants — adults have them too and nobody makes a drama of it. It’s about the child being able to say: „I’m spending on a treat”, „I’m saving for a goal”, „I’m buying something I need”. That builds awareness without moralizing, and along the way it makes the later conversation about budgeting easier.

A bank account for a child — from what age you can open one

Now the heart of the matter, which is probably why you’re reading this. In Poland a child can hold a bank account regardless of age. The Financial Ombudsman (Rzecznik Finansowy) explains that a minor can have a savings account, a personal current account or a term deposit — this rule follows from Article 58 of the Banking Law and Article 8 § 1 of the Civil Code.

That doesn’t mean, however, that every child can do anything they like with the account. In practice there are three levels of independence, depending on age.

Child’s age	What it means in practice
under 13	the parent/guardian opens and runs the account; the child doesn’t dispose of the funds independently
13–18 years	limited capacity for legal acts; broader access to the account, but under the parent’s control
from 18	full legal and banking independence

Once they turn 13, a child gains limited capacity for legal acts. The Financial Ombudsman points out that a teenager can enter into an account agreement, but its validity depends on confirmation by a statutory representative — in practice it’s a parent or guardian who signs the documents and gives consent. In plain terms: the account „belongs” to the teenager, but it still starts through you.

What a teenager can do after turning 13

Here’s a point worth understanding precisely, because it’s sometimes a source of family misunderstandings. Under Article 58 of the Banking Law, a minor account holder can, after turning 13, freely dispose of the funds held, as long as their statutory representative doesn’t object to it in writing. The Financial Ombudsman explains that this can include transfers, cash withdrawals and card payments.

In other words: by default the teenager decides, and you have the right to narrow that scope — with a written objection. It’s the opposite of what many parents assume. That’s why a teenager’s account shouldn’t be just a technical add-on to pocket money. It’s a tool for learning how to check the balance, plan spending to the end of the month, tell a card payment from a transfer, why you never share a BLIK code, and what to do after losing a phone or a card.

There is, however, a hard limit. The Financial Ombudsman points out that a minor can only dispose of money within a positive balance and cannot run the account into an overdraft. A teenager’s account is not an adult’s account — no credit limit, no overdraft, no way to go below zero.

Does the money in a child’s account belong to the parent?

Short answer: not in the way it might seem. It’s a common error in thinking — treating a child’s account like your own „compartment”. The Financial Ombudsman points out that a parent cannot freely dispose of the money held in a child’s account. Parents manage a child’s property with due care, but acts exceeding ordinary administration require the permission of the guardianship court.

This matters especially with larger sums: gifts from grandparents, compensation payments, inheritances or savings set aside „for the child’s future”. In practice it’s worth separating two things. An educational / pocket-money account — small amounts, everyday spending, learning independence. The child’s assets — funds meant to serve them in the future, which shouldn’t be freely spent on the household’s current needs.

This distinction protects the child above all, but you too — because with larger sums „ordinary administration” ends sooner than you’d think, and the guardianship court isn’t a formality for show.

How to choose an account for a teenager

Don’t choose an account for a pretty advert or a sign-up bonus. An account for a child should be, above all, safe, simple and controllable. The rest is an extra.

Item	What to watch out for
Account fee	Whether it’s unconditionally free or you have to meet conditions
Card fee	Whether the card is free and whether it requires transactions
ATM withdrawals	Which ATMs are free
Mobile app	Whether it’s simple and clear for a teenager
Limits	Whether you can set daily, monthly, online and cash limits
Online payments	Whether they can be turned off or restricted
BLIK	Whether it’s available and from what age
Notifications	Whether you can see the child’s transactions
Card blocking	How quickly you can block the card or the app
No overdraft	Whether the account prevents going below zero

The most important thing is limits. A teenager should have room for independence, but shouldn’t have the technical ability to make a very expensive mistake with a single click. A limit isn’t a lack of trust — it’s a protective barrier, like a helmet when learning to ride a bike.

An account doesn’t replace conversation

Simply opening an account doesn’t teach finances. An account without conversation can even do harm, because the child gets a tool they don’t understand. It’s a bit like handing someone the keys without a single driving lesson.

A good habit is a short „financial meeting” once a month with your teenager. Not an inspection, just a conversation: how much came in, how much is left, what the most went on, whether some expense was a misfire, whether they managed to set anything aside, and whether all the subscriptions are still needed. That last question can be an eye-opener — because a fixed cost that quietly leaves the account every month is easiest to see only once you name it.

This habit has solid backing in the data. The OECD notes that students who talk with their parents about purchasing decisions and saving achieve better results in financial knowledge. That’s a serious argument against the „here’s a card, sort it out yourself” approach.

First goals and first earnings

A child should experience saving up for something bigger as early as possible. It doesn’t have to be anything spectacular — headphones, a game, a scooter, a trip. What matters is that the goal is concrete, visible, countable and partly funded by the child.

Example works better than a lecture.

At ages 16–18 the conversation about money should go beyond pocket money — a summer job, tutoring and first gigs come into the picture. It’s the moment to explain the difference between gross and net pay, the habit of reading a contract before signing it, the rule that wages land in an account, and that you don’t give account access to strangers. It’s also worth naming outright the „fake transfer”, „fake BLIK” and „fake investment” scams before the teenager starts acting fully on their own.

During Global Money Week 2026, the UKNF (the office of Poland’s Financial Supervision Authority, KNF) stressed the importance of talking with young people about, among other things, a first paycheck, entering into contracts, tracking spending and protection against financial fraud. These are exactly the topics that are best brought up at home sooner rather than later.

A practical plan: from piggy bank to account

What pays off most is grading responsibility — small steps instead of one leap into adulthood. You could adopt a model like this.

1. 4–6 years — play and observation. Coins, playing shop, a first transparent piggy bank. Simple language: „this costs money”, „we pick one thing”, „we’re saving for later”.
2. 6–9 years — first pocket money. Small, regular amounts. The child learns that if they spend it all at once, they have to wait.
3. 10–12 years — goals and simple planning. Saving up for bigger things, comparing prices, first caution toward online shopping and games.
4. 13–15 years — account, card and limits. A good time for a youth account with sensible limits. Transfers, balance, history, security, a monthly budget.
5. 16–18 years — greater independence. First earnings, covering part of their own costs, the basics of contracts and digital security.

The goal isn’t for the child to never make a mistake. The goal is for them to make small mistakes early, under your care, instead of big mistakes as an adult. A child who once blows their whole pocket money on something silly will remember more than from ten lectures about saving.

The best model is neither full control nor full freedom, but controlled independence: their own money, their own decisions and their own small mistakes — within the limits you set. Thanks to that, the child enters adulthood with practice, not just theory. And in personal finance, practice is sometimes more important than the nicest definition.

Najczęściej zadawane pytania

From what age can you open a bank account for a child?

In Poland a child can hold a bank account at any age — Article 58 of the Banking Law and Article 8 § 1 of the Civil Code allow it. Up to age 13 the account is opened and run by a parent or guardian, and the child doesn’t dispose of the funds independently. After turning 13 the scope of independence grows. The specific age thresholds for a card or an app, however, are set by each bank in its own offer, so it’s worth checking the terms of the account you choose.

Can a teenager withdraw money from the account on their own?

Usually yes. Under Article 58 of the Banking Law, a minor account holder can, after turning 13, freely dispose of the funds held — including making transfers, withdrawing cash and paying by card — as long as their statutory representative doesn’t object to it in writing. So it’s you who has the right to narrow that scope, not the other way around. The limit is a positive balance: the teenager cannot run the account into an overdraft.

Does the money in a child's account belong to the parent?

Not in the sense of freely disposing of it. The Financial Ombudsman points out that a parent cannot spend the funds from a child’s account at will. Parents manage a child’s property with due care, but acts exceeding ordinary administration require the consent of the guardianship court. This matters especially with larger sums, such as gifts from grandparents, inheritances or compensation payments.

How much pocket money should you give a child?

There’s no single right amount — it depends on age, where you live, the family’s situation and what the child is supposed to cover with that money. A simple rule applies: the younger the child, the smaller the amount and the shorter the period, ideally weekly. For a teenager, monthly pocket money can be better, because it resembles an adult budget. The amount should be felt enough that something can be planned, but not so high that every whim is available on the spot.

Can a teenager's account have an overdraft or a credit card?

No. The Financial Ombudsman points out that a minor can only dispose of money within a positive balance and cannot run the account into an overdraft. A teenager’s account therefore has, by design, no credit limit or overdraft. When choosing an account it’s worth making sure it doesn’t allow going below zero, and setting transaction limits to reduce the risk of an expensive mistake.

Should you pay a child for grades?

It depends on the goal, but it’s usually better to avoid it. Paying for every good grade can work in the short term, but it carries the risk that the child starts treating learning like a service sold to their parents. It often makes more sense to separate three areas: household chores as part of family life, learning as an investment in oneself, and separately the extra tasks you really can pay for. The child should understand that money is most often the result of work and responsibility, not of simply „being good”.
