Can I Transfer Stocks to My Child? Gift Tax and Kiddie Tax Rules

Transferring stocks to your child is straightforward: you open a custodial account in the child’s name, move the shares in, and manage them until the child reaches the age set by your state. In 2026, each parent can give up to $19,000 in stock per child before any gift tax paperwork is required, and a married couple electing gift splitting can move up to $38,000 per child per year. The transfer itself is the easy part. The parts that catch families off guard are cost basis, the kiddie tax, and what a custodial account does to college financial aid.

The Account You’ll Use

Stock transfers to a minor go through either a UGMA (Uniform Gifts to Minors Act) or UTMA (Uniform Transfers to Minors Act) custodial account. Both let an adult custodian manage investments held in the child’s name. UGMA accounts are limited to financial assets: cash, stocks, bonds, mutual funds. UTMA accounts accept those plus real estate, intellectual property, and other non-financial property. For a stock transfer, either works.

One rule matters more than any other: every transfer into a UGMA or UTMA is irrevocable. Once the shares are in, the money legally belongs to the child. You cannot pull it back, redirect it to a sibling, or use it for your own expenses. You are managing it on the child’s behalf.

When Your Child Takes Control

Control shifts to the child at the termination age set by state law. Most states default to 21; several set it at 18. California, Florida, Nevada, Ohio, Oregon, and Washington are among the states that let the donor extend the termination age up to 25 at the time the account is opened. Wyoming allows extensions as far as 30. Once the child reaches the termination age, the assets are theirs to spend however they choose. That loss of control is the biggest drawback of the custodial route, and it deserves real thought before you move a significant portfolio.

How to Make the Transfer

Open a custodial brokerage account in the child’s name. You’ll need the child’s full legal name and Social Security number, along with the custodian’s identifying information. Most major brokerages charge no annual fee; some smaller institutions charge maintenance fees up to about $50 or $60 a year.

Once the account exists, initiate the transfer by specifying the ticker symbols, share counts, and the sending and receiving account numbers. Most brokerages handle this through an online portal. Double-check the ticker. Plenty of transfers have gone sideways because a parent entered the symbol for a similarly named ETF instead of the intended individual stock.

Electronic transfers through ACATS, the automated system brokerages use, typically settle within six business days when nothing goes wrong. The SEC notes that manual or paper-based transfers can stretch to two or three weeks when complications arise.¹ After the transfer settles, keep your own records of the transfer date and the shares’ original cost basis. You’ll need both later.

If You Hold Paper Certificates

Physical stock certificates add steps. You complete a stock power form, which authorizes the transfer of ownership without writing on the certificate itself. The transfer also requires a Medallion Signature Guarantee, a specialized verification stamp that protects against forged signatures on securities transfers. Banks, credit unions, and brokerages that participate in a recognized guarantee program can provide the stamp. Most provide it free to existing customers and may refuse non-customers outright, so plan on handling it where you already have a relationship.²

Gift Tax Rules

The annual gift tax exclusion for 2026 is $19,000 per recipient.³ Transfer up to that amount in stock to each child in a single year and no gift tax paperwork is required. If both parents want to give, gift splitting treats a joint gift as if each spouse gave half, effectively doubling the exclusion to $38,000 per child per year. Both spouses must consent on the tax return for gift splitting to apply.⁴

Move more than the exclusion amount to any one recipient and you have to file IRS Form 709, even when no tax is actually due.⁵ The excess reduces your lifetime estate and gift tax exemption, which is $15 million per individual in 2026.³ Unless the transfer is truly large, you won’t owe gift tax. But skipping a required Form 709 can create problems with the IRS later. The form is due with your income tax return for the year of the gift.

Cost Basis and What Your Child Owes at Sale

This is where most families underestimate the tax bill. When your child eventually sells the stock, capital gains are calculated from your original cost basis, not from what the shares were worth on the day you transferred them.

The general rule: your child inherits your basis. If you bought shares at $20 and transferred them when they were worth $100, the child’s basis is $20. Sell at $120 and the taxable gain is $100 per share.⁶

There’s a wrinkle when the stock has fallen below what you paid. If the fair market value at the time of the gift is less than your basis, the rules split. For calculating a gain, the child uses your original basis. For calculating a loss, the child uses the lower fair market value at the time of the gift. If the child later sells at a price between those two figures, there is no gain and no loss.⁷ The practical effect: gifting a losing position destroys part of the capital loss you could have used yourself. If a stock is down and you want the tax benefit of the loss, sell it, then gift the cash.

Your child also inherits your holding period. Shares you held for three years count as three years of holding time in the child’s hands, which usually means a sale qualifies for long-term capital gains rates rather than short-term rates.⁸

The Kiddie Tax on Investment Income

Transferring stock to a child does not let you escape your own tax bracket. The kiddie tax applies to unearned income (dividends, interest, capital gains) earned by children under 19, or under 24 if they’re full-time students.

For 2026, the tiers work like this:⁹

The first $1,350 of unearned income is covered by the child’s standard deduction and untaxed.
The next $1,350 is taxed at the child’s own rate, which is typically very low.
Anything above $2,700 is taxed at the parent’s marginal rate.

When the child’s unearned income tops $2,700, Form 8615 goes with the child’s return. Alternatively, if the child’s total gross income is between $1,350 and $13,500 and comes only from interest and dividends, you can elect to report it on your own return using Form 8814.¹⁰ Children with net investment income above the applicable threshold may also face the 3.8% net investment income tax.

The kiddie tax doesn’t wipe out the reason to transfer stock, but it caps the annual tax-shifting benefit at roughly the first $2,700 of investment income per child. For a modest portfolio, that’s a real if small savings. For a large one, most of the income comes back to your bracket anyway.

Impact on College Financial Aid

If college is on the horizon, a custodial account has a cost most parents don’t see coming. The FAFSA uses the Student Aid Index to determine aid eligibility, and student-owned assets get hit harder than parent-owned assets. Stocks in a UGMA or UTMA belong to the child and are assessed at a 20% conversion rate in the SAI formula.¹¹

Parental assets are assessed at 12% under the current SAI formula.¹¹ A $50,000 custodial account cuts aid eligibility by $10,000 under the student rate, compared with $6,000 if the same assets were held in your name. For families expecting need-based aid, holding the appreciated stock in your own account and paying for college directly can leave the child better off than moving the shares into a UGMA years earlier.

Other Ways to Invest for Your Child

A custodial account is not the only path, and depending on what you’re trying to accomplish, another vehicle may fit better.

529 Education Savings Plans

If the money is specifically for school, a 529 offers tax advantages a UGMA or UTMA can’t match. Earnings grow tax-free, and withdrawals for qualified education expenses owe no federal income tax. Gains inside a custodial account, by contrast, are taxable in the year they’re realized. You can also change the beneficiary of a 529 to another family member without tax consequences, flexibility a custodial account does not offer.¹²

The same $19,000 annual exclusion applies to 529 contributions, and a special provision lets you front-load up to five years of contributions at once, or $95,000 per donor in 2026, without gift tax consequences, provided you make no additional gifts to that beneficiary during the five-year window. The tradeoff: withdrawals for anything other than education expenses trigger income tax and a 10% penalty on the earnings portion. If you want your child to have the money whether or not they go to college, a custodial account keeps more options open.

Custodial Roth IRA

If your child has earned income from a job, babysitting, or freelance work, a custodial Roth IRA in their name is worth a look. The 2026 contribution limit is $7,500, but contributions can’t exceed the child’s actual earnings for the year.¹³ You can fund the contribution with your own money as long as the child earned at least that much.

You cannot transfer existing stock directly into a Roth IRA; contributions have to be cash. So this is not a substitute for moving specific shares. But for long-term wealth building, the tax-free growth is difficult to beat, and decades of compounding on even modest early contributions can produce real results.
