US Crypto Taxes for Minors: What Parents Need to Know About Teen Traders in 2026

US Tax Mar 26, 2026

Your 16-year-old made $5,000 trading Solana memecoins. Now what?

The IRS doesn't care how old you are. Minors who trade crypto owe taxes just like adults—and their gains might be taxed at your rate, not theirs.

Here's what parents need to know about crypto taxes for minors, the "kiddie tax," filing requirements, and whether you're on the hook for your teen's unpaid taxes.


Can Minors Legally Trade Crypto?

Most major exchanges prohibit users under 18:

Exchange

Minimum Age

Coinbase

18+

Kraken

18+

Binance.US

18+

Cash App

13+ (with parent supervision)

Why? KYC regulations require identity verification, and minors can't legally enter binding financial contracts in most states.

But minors still trade. They use:

  • UTMA/UGMA custodial accounts
  • Parent-supervised accounts (Cash App Sponsor Accounts)
  • Decentralized exchanges (no KYC, but still taxable)
  • Parents trading on their behalf

If your minor child trades crypto through any of these methods, they have tax obligations.


When Must a Minor File a Tax Return?

A dependent must file a tax return if their income exceeds these thresholds:

2025 Filing Thresholds for Dependents

Income Type

Filing Required If

Unearned income only

More than $1,350

Earned income only

More than $15,750

Both types

Gross income exceeds the larger of: $1,350 OR (earned income + $450, up to $15,750)

Crypto gains count as unearned income.

Example: Your teen has no job but made $2,000 in crypto gains. They must file because $2,000 exceeds the $1,350 threshold.


The Kiddie Tax: Your Teen's Gains, Your Tax Rate

The "kiddie tax" prevents parents from shifting investment income to children to exploit lower tax brackets. It applies to most minors with investment income.

How the Kiddie Tax Works (2025)

Income Layer

Tax Treatment

First $1,350

Tax-free (covered by standard deduction)

Next $1,350 ($1,351–$2,700)

Taxed at child's rate (typically 10%)

Above $2,700

Taxed at parent's marginal rate

Example: Your 16-year-old makes $10,000 trading Solana tokens.

  • First $1,350: Tax-free
  • Next $1,350: Taxed at 10% = $135
  • Remaining $7,300: Taxed at your rate (say 24%) = $1,752
  • Total tax: $1,887

Without the kiddie tax, your teen would pay roughly $865 at their own rate. The kiddie tax more than doubles their bill.

Who Does the Kiddie Tax Apply To?

Age

Applies If

Under 18

Always applies

Age 18

Applies if earned income is less than half their support

Ages 19–23

Applies if full-time student AND earned income is less than half their support

If your teen has a part-time job that covers more than half their expenses, the kiddie tax may not apply after age 18.


Form 8615: The Kiddie Tax Form

Your minor must file Form 8615 when ALL of these are true:

  1. Unearned income exceeds $2,700
  2. Child is required to file a return
  3. Child is under 18 (or 18-23 with support limitations)
  4. At least one parent was alive at year-end
  5. Child does not file a joint return

Form 8615 requires your tax information. You'll need to provide:

  • Your taxable income
  • Your filing status
  • Your marginal rate information

The form uses your information to calculate the correct tax on your child's investment income.

Alternative: Form 8814

If your child's income is under $13,500 and consists only of interest and dividends (not capital gains), you can elect to report it on your own return using Form 8814 instead of filing a separate return for the child.

Warning: This often results in higher taxes than filing separately. Run the numbers both ways.


Are Parents Liable for a Minor's Unpaid Taxes?

No—parents are not directly liable for a minor's unpaid crypto taxes.

The IRS pursues the taxpayer (the minor), not the parent. However:

  • If parents claim the child as a dependent, incorrect information affects the parent's return
  • IRS can pursue collection from the child once they reach adulthood
  • The statute of limitations does not start until a return is filed
  • Unpaid taxes accumulate interest and penalties indefinitely

The real risk: Your teen doesn't file, turns 18, and inherits years of unfiled returns with compounding penalties. By age 25, a few thousand dollars in unpaid taxes becomes a five-figure problem.


Parents' election to report child's interest and dividends

You may be able to elect to report your child's interest, ordinary dividends, and capital gains distributions on your return. If you make this election, your child won't have to file a tax return. To make this election, attach Form 8814 PDF PDF to your Form 1040, Form 1040-SR or Form 1040-NR if your child meets all of the following conditions.

  • At the end of the tax year your child was under age 19 (or under age 24 if a full-time student).
  • Your child's gross income was less than $13,500 for the tax year.
  • Your child had income only from interest and dividends (including capital gain distributions and Alaska Permanent Fund dividends).
  • No estimated tax payments were made for your child for the tax year, and no overpayment from the previous tax year (or from any amended return) was applied to the current tax year under your child's name and Social Security number.
  • No federal income tax was withheld from your child's income under the backup withholding rules.
  • Your child is required to file a return unless you make this election.
  • Your child doesn't file a joint return for the tax year.
  • You're the parent qualified to make the election or you file a joint return with your child's other parent.

Penalties for Minors Who Don't File

Standard IRS penalties apply regardless of age:

Penalty Type

Amount

Failure to file

5% per month (max 25%)

Failure to pay

0.5% per month (max 25%)

Minimum late filing penalty (60+ days)

$525 or 100% of tax owed, whichever is less

Interest

Compounds daily (federal short-term rate + 3%)

Critical: The statute of limitations does not begin until a return is filed. The IRS can pursue unfiled returns indefinitely.

A minor who doesn't file at 16 could face IRS collection actions at 26—with a decade of accumulated penalties.


Who Signs a Minor's Tax Return?

If the minor can sign: The minor signs their own return. There's no IRS age cutoff.

If the minor cannot sign: A parent or guardian signs using this format:

[Child's name], by [Parent's signature], parent for minor child

In practice:

  • Children under 10: Parent typically signs
  • Older teens: Can sign their own return
  • The parent claiming the dependent does NOT automatically have to sign

UTMA/UGMA Custodial Accounts

Many parents use custodial accounts (UTMA/UGMA) to hold crypto for minors.

Tax Implications

  • The minor is the legal owner and taxpayer
  • 1099 forms are issued in the minor's name and SSN
  • All kiddie tax rules apply
  • The custodian manages reporting until the minor reaches majority age (18-21 depending on state)

When the Child Reaches Majority

  • Account transfers fully to the child
  • Child becomes solely responsible for tax reporting
  • No step-up in basis—original cost basis carries over

Example: You bought SOL at $20 in your child's custodial account. They turn 21, take control, and sell at $150. Their cost basis is still $20—they owe tax on the full $130 gain.


What Counts as Unearned Income for Minors?

All crypto activity generates unearned income for kiddie tax purposes:

Activity

Income Type

Selling crypto for profit

Capital gain (unearned)

Swapping one crypto for another

Capital gain (unearned)

Staking rewards

Ordinary income (unearned)

Airdrops

Ordinary income (unearned)

DeFi yields

Ordinary income (unearned)

NFT sales

Capital gain (unearned)

Even a part-time job doesn't change this. Wages are earned income; crypto profits are unearned. Both count toward filing thresholds, but only unearned income triggers the kiddie tax.


Tax Planning for Minor Crypto Traders

Stay Under the Thresholds

Threshold

Strategy

Under $1,350

No tax owed, no filing required (but filing starts statute of limitations)

$1,351–$2,700

Taxed at child's rate only (typically 10%)

Above $2,700

Kiddie tax applies—taxed at parent's rate

If your teen's gains are approaching $2,700, consider whether to realize more gains this year or defer to next year.

Tax-Loss Harvesting

Minors can harvest losses just like adults:

  • Sell losing positions before year-end
  • Use losses to offset gains
  • Deduct up to $3,000 against other income
  • Carry forward excess losses

No wash sale rules apply to crypto—your teen can repurchase immediately.

File Even If No Tax Is Owed

Filing starts the 3-year statute of limitations. If your teen's income is below the filing threshold, consider filing anyway with $0 owed. This protects against IRS claims years later.


Record Keeping for Minor Traders

Keep documentation for at least 7 years:

Record

Why It Matters

Transaction dates

Determines holding period

Purchase price in USD

Establishes cost basis

Sale price in USD

Calculates gain/loss

Wallet addresses

Proves ownership

Exchange records

Supports reported transactions

Transaction hashes

Blockchain verification

Crypto tax software automates this. Connect wallets, generate reports, and keep records organized.


Common Questions

My teen used my exchange account. Whose taxes are affected?

If trades happened in your account, the income is reported on your return. You'd owe the taxes, not your child.

If you then gifted the profits to your child, gift tax rules apply (under $18,000/year is tax-free).

What if my teen traded on a DEX with no KYC?

Still taxable. The IRS requires reporting all crypto transactions regardless of whether an exchange issued a 1099. Blockchain transactions are public and traceable.

Can I claim my teen's crypto losses on my return?

No. Losses belong to the taxpayer who owns the assets. If your child's custodial account has losses, those losses offset their gains, not yours.

What if my teen didn't know they had to file?

Ignorance isn't a defense. File amended or late returns as soon as possible. Penalties continue accruing until you file.


Summary

Minors who trade crypto face real tax obligations:

  1. Filing threshold is low — Unearned income over $1,350 requires a return
  2. Kiddie tax applies — Income over $2,700 is taxed at the parent's rate
  3. Parents aren't liable — But the minor inherits the problem as an adult
  4. Penalties compound — Unfiled returns accumulate interest indefinitely

Don't let your teen's trading hobby become a five-figure tax problem at 25. Track transactions, file returns, and treat crypto taxes seriously—regardless of age.
