Gifting Crypto to a Child: Custodial Accounts and Tax Traps

Researched and last reviewed September 2026 · Written by the GiftMeCrypto research desk

The quick verdict

4.0/ 5

A genuinely good gift, spoiled easily by the mechanics. A custodial account is the realistic choice for most families; self-custody works only if you can guarantee seed-phrase security for a decade. Keep the amount modest, keep the records, and take advice before anything large.

Best structure: Custodial account, adult-managed
Riskiest structure: Self-custody with a paper seed
US tax note: Kiddie tax on unearned income above thresholds
Canada tax note: Attribution can bounce gains to you
Must keep: Acquisition date, cost, gift date

The four options

Structures for holding a child's crypto
Structure	Who controls it	Main risk	Best for
Custodial account (UTMA/UGMA-style)	Adult custodian until majority	Provider availability for crypto	Most families
Adult's own account, earmarked	The adult, informally	No legal separation; tax sits with you	Small amounts, short horizon
Hardware wallet, adult holds seed	Adult, then child	Seed loss is total and permanent	Technically confident families
Hold and transfer later	The adult, until a chosen date	Requires you to actually do it	When no structure is available

Custodial account — the default recommendation

An adult opens and manages the account; the assets legally belong to the child; control transfers at the age of majority. This is the structure designed for exactly this situation, and its main practical limitation is that not every provider supports crypto inside it. Check that before committing to the plan.

Your own account, earmarked mentally — the common shortcut

Widely done and worth understanding honestly: it is not a gift. The asset is legally yours, the tax consequences are yours, and if your circumstances change the money is exposed to your creditors and your estate rather than being the child's. For a small amount over a couple of years that may be acceptable. For a meaningful long-term gift it is not what it appears to be.

Self-custody with an adult holding the seed — highest risk

Think in decades before choosing this A seed phrase has to survive house moves, water damage, forgotten hiding places and — over a fifteen-year horizon — the possibility that you are not around to explain it. Self-custody removes platform risk and introduces total-loss risk. If you choose it, write the seed on metal, store it in two separate places, and leave clear written instructions with your estate documents. See our paper wallet guide for what can go wrong.

The tax traps

Three jurisdiction-specific issues that catch families out. None is exotic and all are easier to handle before the gift than after.

US — the kiddie tax. A minor's unearned income above certain thresholds can be taxed at the parent's marginal rate rather than the child's. That undercuts the assumption that holding assets in a child's name is automatically tax-efficient. Thresholds change; check the current year.
Canada — attribution. Income and, in some circumstances, gains on property gifted to a minor child can be attributed back to the giver's return. Our Canada page covers this.
UK — settlements rules. Income arising on assets a parent gives to a minor child can be treated as the parent's. Gifting is also a capital-gains disposal in the UK, so you may realise a gain on the way in.

None of this makes gifting to a child a bad idea. It means the structure and the amount should be chosen with the rules in view, and that for anything material you should pay a professional. Start at our tax hub.

Records that protect them

This matters more for a child than for any other recipient, because the horizon is long enough that memory will not do the job.

Record the acquisition Asset, amount, the date you bought it, and what you paid.
Record the gift The date it was given and the market value on that date.
Record the structure Which account, which provider, who the custodian is.
Store it where it will be found With your estate paperwork, not only in an email account. Tell one other adult it exists.
Update it if you add to the gift Each addition has its own date and cost basis.

Why this is the most valuable part In the US the child inherits your cost basis, and in fifteen years there will be no other source for it. A single page of records is the difference between a clean tax position and a guess that could cost them real money.

What happens at 18

With a custodial account, control transfers at the age of majority — which is a feature and occasionally a surprise. The child gains full control of assets that may by then be substantial, and there is no mechanism to delay it.

Talk to them about it before it happens, not on the day
Hand over the records at the same time as the account
If self-custody is the eventual plan, do the seed handover in person and verify they can access it
Expect the asset to be sold. That is their right, and it is not a failure of the gift

From our research desk

The best crypto gift to a child I have come across was $100 of bitcoin in a custodial account, plus a printed card showing the block height on the day the child was born and a paragraph explaining what a block is. The amount was small. The explanation is what made it a gift rather than a transfer.

The failure mode I would most warn against is the mental earmark — holding it in your own account and calling it theirs. It is well-intentioned and it is not a gift: the tax is yours, the legal ownership is yours, and if anything happens to you it does not reach the child at all. If it is meant to be theirs, put it somewhere it actually is.

Frequently asked questions

Can you gift crypto to a minor?

Yes, but a child generally cannot hold an exchange account in their own name — most platforms require account holders to be 18 or older. So the gift has to be held in a structure: a custodial account opened by an adult for the child's benefit, an account the parent controls informally, or self-custody where an adult holds the keys until the child is old enough.

What is a custodial account?

An account an adult opens and manages for a minor's benefit, with the assets legally belonging to the child. In the US these are commonly UTMA or UGMA accounts. The custodian manages it until the child reaches the age of majority in their state, at which point control transfers to them. Availability for crypto specifically varies by provider, so check before assuming.

Who pays tax on a child's crypto gains?

In the US, the child does — but above certain thresholds, unearned income of a minor can be taxed at the parent's marginal rate under the so-called kiddie tax rules. In Canada, attribution rules can push income or gains on gifts to a minor back onto the giver's return. In the UK, similar settlements rules can apply to gifts from a parent. Take advice before a large gift.

Should I use a hardware wallet for a child's crypto?

Only if you are confident you can manage seed-phrase security for a decade or more. Self-custody removes platform risk and introduces total-loss risk: a lost seed phrase is unrecoverable, and the time horizon here is very long. For most families a custodial account with a reputable provider is the more realistic choice, with self-custody as an option once the child is old enough to be involved.

How much should I gift a child?

Small and long-horizon is the point. A modest amount that can compound for fifteen years is a better gift than a large amount that dominates their attention. It also stays well inside gift-tax thresholds — the US annual exclusion is $19,000 per recipient in 2026, so ordinary family gifts are nowhere near it.
