Saving and Investing for Children in Denmark: The Four Accounts Explained

Denmark gives you a decent toolkit for saving on your kids’ behalf. The problem: none of it is explained in English, the rules interact in ways that aren’t obvious, and getting the parent-versus-grandparent distinction wrong means your child pays tax that was entirely avoidable.

Four main structures exist. They’re not interchangeable. Here’s how each works, and the order to use them.

1. Børneopsparing: The Only Fully Tax-Free Option

The børneopsparing is the place to start. It’s the only savings structure in Denmark where interest, dividends, and capital gains are completely tax-free for the duration of the binding period. No income tax. No capital gains tax. Nothing.

That’s a meaningful statement in a country where most investment returns are taxed somewhere between 17% and 42%.

The rules, drawn from Pensionsbeskatningsloven § 51:

You can invest the money in stocks, bonds, and funds, not just park it in cash. Most traditional banks let you choose your own investments within the account, though some only offer their own pooled products (puljeinvestering). If you plan to invest actively, check what the bank allows before you open the account.

Where to open it. Børneopsparinger must be opened at a traditional Danish bank: Danske Bank, Nordea, Jyske Bank, Sydbank, and others. Nordnet and Saxo Bank don’t offer them. The account is in the child’s name and linked to their CPR number.

The maths, for context. If you deposit DKK 6,000 per year from birth and invest at a conservative 5% annual return, the account reaches roughly DKK 125,000 by the time the child turns 21. At 7% it’s closer to DKK 150,000. Every krone of that growth comes out tax-free.

2. Free Depot: Using the Child’s Personfradrag

Once the børneopsparing is maxed out, a regular investment account (frit depot) in the child’s name is the next step. The strategy here is different: you’re using the child’s personfradrag to keep returns below the taxable threshold.

In 2026, the personfradrag is DKK 54,100. If your child’s kapitalindkomst (capital income) stays below that figure, they pay no Danish tax on it.

For this to work, you need to invest in assets taxed as kapitalindkomst: specifically, accumulating funds not on SKAT’s Positivliste. Assets on the Positivliste are taxed as aktieindkomst, and children don’t get a personfradrag against aktieindkomst.

One important caveat: Positivliste status changes every January. A fund that qualifies as kapitalindkomst this year can move onto the list next year, silently switching its tax treatment to aktieindkomst. Check your holdings each January before the new tax year begins.

The parent-versus-grandparent rule. This is where it gets important:

If the money came from grandparents, all returns (dividends, interest, and capital gains) are taxed in the child’s name. That’s the ideal scenario, because the child’s personfradrag can shelter the lot.

If the money came from the parents (or step-parents), ongoing income like dividends and interest is taxed in the parent’s name, not the child’s. Capital gains on the investments are still taxed in the child’s name.

This is why grandparent money is so powerful here. Each grandparent can gift up to DKK 80,600 per year to the child with no gift tax, and if that money goes into the depot, any returns within the personfradrag threshold are also tax-free.If the money is from parents, opt for accumulating (akkumulerende) funds that don’t pay out dividends. That way, there’s no ongoing income to be taxed in the parent’s name. Only capital gains on eventual sale, which are always taxed in the child’s name regardless of who gave the money.

3. Aktiesparekonto: 17% Tax, Including for Children

Yes, children can hold an aktiesparekonto (ASK). A parent can open one on their child’s behalf. The same rules apply as for adults: a flat 17% on annual gains, calculated on a mark-to-market basis each year (lagerbeskatning).

In 2026:

One important distinction from the free depot: the rule that attributes ongoing returns on parental gifts back to the parent does not apply inside the ASK. The ASK is a closed tax environment. Even if the money came from Mum and Dad, the 17% tax stays on the ASK. It’s not pushed back to the parents.

Where it sits in the priority order. The ASK makes most sense after you’ve exhausted the børneopsparing and the personfradrag strategy on the free depot. A DKK 54,100 personfradrag gives you a 0% rate; the ASK charges 17%. Once the child’s capital income exceeds the personfradrag threshold, the ASK’s 17% rate beats the standard 27%–42% aktieindkomst rates.

A note for American parents. The PFIC rules that complicate the ASK for adult Americans apply equally to ASKs opened for American children. Before opening one, confirm with a cross-border adviser whether the account creates a reporting problem on your or your child’s U.S. return.

4. Aldersopsparing: Compounding Across Decades

This one is genuinely unusual. You can open an aldersopsparing (retirement savings account) for a child from birth. Total contributions across all contributors — parents, grandparents, anyone — are capped at DKK 9,900 per year into the account. Returns are taxed annually at 15.30% (PAL-skat). The money can’t be touched until the child reaches retirement age.

Retirement age, in full. If your child is born in 2026, that’s probably somewhere around 2095.

The maths still work: 15.30% PAL-skat is far lower than the rates that apply in any of the other structures, and 70 years of compounding at that rate produces a genuinely large number. A modest DKK 9,900 contribution every year for 18 years, invested at a 5% real return, would be worth a significant sum by 2095.

Whether that argument lands for you is a values question as much as a financial one. Plenty of parents would rather the money be available at 18 or 21, not 70. But if you’ve already maxed out the other three structures and want to give your child the longest possible compounding runway at the lowest tax rate, this is how you do it.

The Priority Order

This isn’t a rigid rule; circumstances vary. If a child has no Danish-resident grandparents, the free depot strategy is less powerful. If you’re an American, the ASK may not belong in your order at all.

If you’re unsure how the structures interact with your specific residency situation, family setup, or citizenship, this is a good moment to talk to a tax adviser who works with cross-border families in Denmark. The rules aren’t complicated in isolation. They interact in ways that depend on your facts.

Gift Tax: What You Can Give

Any money you put into these accounts is a gift to the child. Denmark allows tax-free gifts up to DKK 80,600 per year, per donor. That threshold applies to parents, grandparents, and step-parents alike, each separately.

Gifts above that threshold are subject to 15% gift tax on the excess.

With the børneopsparing’s DKK 6,000 annual limit, you’re well inside the threshold. But if you’re simultaneously funding a free depot and an ASK, watch the totals, especially if multiple family members are contributing.

What Changed in 2026

From 2026, children under 18 no longer pay labour market contributions (AM-bidrag) on earned income. The exemption applies through the end of the calendar year in which a person turns 17. Someone who turns 18 on any date in 2026 must pay AM-bidrag from 1 January of that year. This change is most material for teenagers with part-time jobs, not for the passive investment structures described in this article.

The personfradrag for children in 2026 is DKK 54,100 for kapitalindkomst — the same as for adults. The ASK deposit limit is DKK 174,200. The børneopsparing limits remain unchanged at DKK 6,000 per year and DKK 72,000 lifetime.

Practical Notes for Expats

Check what investments the bank actually allows in the børneopsparing. Some banks restrict you to their own pooled products, which can carry higher fees and less flexibility. Ask specifically about individual funds and ETFs before you open the account.

Don’t confuse branded “child savings” products with the real børneopsparing. Some fintechs market products as børneopsparing that are technically just regular investment accounts using the child’s personfradrag. A genuine børneopsparing under PBL § 51 must be opened at a traditional bank and has the binding period requirement. These are not the same thing.

Think carefully about binding until 21 rather than 14. You get up to seven more years of tax-free compounding. The trade-off is that the child has no legal access during that time. Many Danish parents choose 21 for exactly that reason.

Route grandparent contributions through the free depot, not the børneopsparing. The børneopsparing takes DKK 6,000 per year regardless of who contributes. Grandparent money is far more powerful in a depot where the gift threshold per grandparent is DKK 80,600 and the child’s personfradrag shelters the returns.

Keep records of who gave what. Banks don’t automatically know or report the source of gifts. SKAT expects parents to attribute dividends correctly: to the parent if the money came from parents, to the child if it came from grandparents. The records are your responsibility.If you leave Denmark: the børneopsparing stays tax-free. It’s not affected by your departure. The free depot and ASK are subject to the same exit-tax rules as any other Danish investment account. Report everything to SKAT before you go.
