You can defer capital gains tax by gifting an appreciated asset, but you cannot make the gain disappear. The recipient takes over your original cost basis, so the built-up profit becomes their tax bill whenever they sell. Whether trying to avoid capital gains by gifting assets actually saves your family money depends on the recipient’s tax bracket, how long you plan to live, and whether the asset has gained or lost value since you bought it.
The Carryover Basis Rule
When you give someone an asset, the recipient inherits your original cost basis rather than starting fresh at the current market value.1Office of the Law Revision Counsel. 26 U.S. Code 1015 – Basis of Property Acquired by Gifts and Transfers in Trust This single rule is what turns gifting into a tax shift instead of a tax escape.
Say you bought stock for $10,000 and it is now worth $60,000. Sell it yourself and you owe capital gains tax on the $50,000 profit. Gift it and you owe nothing. But the person who receives the stock takes your $10,000 basis, not the $60,000 current value. When they later sell for $65,000, they report $55,000 of gain.
The recipient also inherits your holding period. Under the tacking rule, the time you held the asset counts toward theirs.2Office of the Law Revision Counsel. 26 U.S. Code 1223 – Holding Period of Property That matters because assets held longer than a year qualify for long-term capital gains rates of 0%, 15%, or 20% depending on income. If you held the stock for three years before gifting it, the recipient can sell the next day and still get long-term treatment.
Hand over the purchase records with the asset. If the recipient cannot document your original cost and acquisition date, the IRS can treat the basis as zero, which turns the full sale price into taxable gain.
When Gifting Actually Lowers the Tax
The real savings come when the recipient pays a lower rate than you would have. Long-term capital gains rates run from 0% to 20%, so the gap between your bracket and theirs sets the ceiling on what the family saves.
A parent in the 20% long-term bracket who gifts appreciated stock to an adult child with modest income could see that same gain taxed at 0% or 15%. On $100,000 of built-in gain, the difference between 20% and 0% is $20,000. The gain does not shrink; the rate applied to it does.
The 3.8% Surtax
High earners pay an additional 3.8% net investment income tax on capital gains once modified adjusted gross income tops $200,000 for single filers or $250,000 for married couples filing jointly.3Office of the Law Revision Counsel. 26 U.S. Code 1411 – Imposition of Tax Those thresholds are not indexed for inflation. If you would owe the surtax but the recipient falls below the threshold, gifting the asset avoids the 3.8% entirely. Combined with the rate shift on the underlying gain, moving an asset from a high-income donor to a lower-income recipient can cut the effective federal rate from 23.8% to zero.
The Kiddie Tax Blocks the Obvious Move
Gifting appreciated stock to a minor to use the 0% bracket does not work the way it looks. The kiddie tax applies the parent’s marginal rate to a child’s unearned income above $2,700 for children under 18, for 18-year-olds who do not earn more than half their own support, and for full-time students aged 19 through 23 in the same support situation.4Internal Revenue Service. Instructions for Form 8615 (2025)
Capital gains from selling gifted stock count as unearned income. If a 16-year-old sells $50,000 of gifted stock at a gain, most of that profit gets taxed at the parent’s rate. The bracket-shifting strategy works with adult relatives who have their own earned income but still sit in a lower bracket than you.
Why Holding Until Death Usually Wins
Assets passed through an estate get completely different treatment. Instead of carrying over your basis, inherited property gets a stepped-up basis equal to fair market value on the date of death.5Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired from a Decedent Every dollar of appreciation that built up during your lifetime is permanently erased for capital gains purposes.
Property bought for $10,000 that is worth $500,000 when the owner dies gives the heir a $500,000 basis. Sell the next day for $500,000 and there is no taxable gain. The $490,000 that accumulated over decades simply vanishes. Inherited property is also automatically long-term, regardless of when the decedent bought it.2Office of the Law Revision Counsel. 26 U.S. Code 1223 – Holding Period of Property
This is where the gifting decision gets hard. Giving away a highly appreciated asset during your lifetime shifts the tax at a potentially lower rate but locks in the carryover basis and preserves the full gain. Waiting until death wipes the gain out. For assets with enormous embedded appreciation, the step-up almost always wins on pure tax math.
The counterargument is estate planning. Gifting removes the asset’s future growth from your taxable estate. If you expect it to keep appreciating fast and you have a realistic estate tax exposure, moving it out now can save estate tax later. You are trading a certain capital gains benefit for a speculative estate tax benefit, and that trade only makes sense when estate tax is actually in play.
Community Property Doubles the Step-Up
Married couples in community property states get a stronger version of the step-up. When one spouse dies, both halves of community property step up to fair market value, not just the deceased spouse’s half.5Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired from a Decedent In common-law states, only the decedent’s share of jointly held property steps up.
A couple in a community property state holding stock with a $20,000 basis worth $500,000 at the first death gives the survivor a $500,000 basis in the whole position. In a common-law state, the survivor steps up only half, leaving a blended basis of $260,000. The difference can run into six figures of taxable gain.
Never Gift an Asset That Has Lost Value
A special dual basis rule prevents donors from transferring a built-in loss.1Office of the Law Revision Counsel. 26 U.S. Code 1015 – Basis of Property Acquired by Gifts and Transfers in Trust When the asset’s fair market value at the time of the gift is below your basis, the recipient ends up with two different figures:
- For calculating gain, the donor’s original basis applies.
- For calculating loss, the fair market value at the time of the gift applies.6Internal Revenue Service. Property (Basis, Sale of Home, etc.)
Suppose you paid $10,000 for stock now worth $4,000 and you gift it. If the recipient later sells for $12,000, they use your $10,000 basis and report a $2,000 gain. If they sell for $3,000, they use the $4,000 gift-date value and report a $1,000 loss. If they sell for anything between $4,000 and $10,000, they report neither gain nor loss. Part of the economic loss evaporates in that dead zone.
Sell the asset yourself, claim the capital loss on your own return, and gift the cash. Capital losses offset capital gains dollar for dollar, and up to $3,000 of excess loss each year offsets ordinary income.7Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses Gifting the loss asset directly wastes that deduction.
Gift Tax Rules the Donor Still Has to Handle
Gift tax is a separate transfer tax on the donor and runs on its own track from capital gains. You can owe one without the other. Gift tax is based on fair market value at the time of the gift; capital gains tax is based on your original basis.
Each donor can give up to $19,000 per recipient per year with no gift tax consequences and no reporting at all.8Internal Revenue Service. What’s New – Estate and Gift Tax Married couples who elect gift-splitting can give $38,000 per recipient.
Gifts above the annual exclusion do not automatically trigger a tax bill. The excess counts against your lifetime exemption, which is $15,000,000 per individual in 2026.9Internal Revenue Service. Revenue Procedure 2025-32 The 40% gift tax rate only kicks in after you have used the entire exemption, so most donors will never write a gift tax check.
Any gift to one recipient that exceeds the $19,000 annual exclusion still requires filing IRS Form 709, even when no tax is due.10Internal Revenue Service. About Form 709, United States Gift and Generation-Skipping Transfer Tax Return The return is due by April 15 of the following year, and an income tax extension also extends Form 709.11Internal Revenue Service. Filing Estate and Gift Tax Returns The IRS uses Form 709 to track cumulative use of your lifetime exemption, and missing returns create problems for your estate later.
When Gifting Makes Sense
Gifting appreciated assets works in a narrow set of circumstances. The ideal case: an asset with moderate appreciation, a recipient in a meaningfully lower bracket, and a donor whose estate is unlikely to face estate tax. The carryover basis is a manageable cost, the rate shift produces real savings, and giving up the step-up at death does not matter because the estate exemption would have sheltered the asset anyway.
The math tilts against gifting when the asset has enormous built-in gain relative to its basis, or when the donor has realistic estate tax exposure. An asset bought for $50,000 and now worth $2 million carries $1,950,000 of embedded gain. Gifting it shifts the entire gain to the recipient at their rate. Leaving it in the estate eliminates it through the step-up. Unless the recipient’s rate is dramatically lower and the asset is expected to keep growing fast enough to create an estate tax problem, holding until death wins.
The worst mistake is gifting a loss asset instead of selling it and gifting the cash. The second worst is gifting appreciated assets to minors or dependent students without accounting for the kiddie tax, which can erase the entire bracket-shifting benefit.
