A parent gifts \$100,000 to an adult child. The child uses \$100,000 to pay down a mortgage and that’s the end of the tax story, no income to the recipient, no income-tax consequences on either side, the gift consumes a small slice of the parent’s lifetime exemption under IRC §2503 and §2010(c). A different parent gifts \$100,000 worth of long-held appreciated stock with a \$10,000 cost basis to a different adult child. The child immediately sells the stock and recognizes a \$90,000 long-term capital gain, the same \$100,000 cash to spend after taxes, but only after roughly \$13,500-\$18,000 of federal capital gains tax depending on the child’s bracket. A third parent transfers a 10% interest in a closely held family business with a \$100,000 stated value to a third adult child. The reportable gift may be only \$70,000 (after applying valuation discounts for lack of marketability and lack of control), the transferred interest could be worth substantially more than the discounted value to the family unit over time, and the income-tax basis the child inherits depends entirely on whether the transfer is structured as a gift, sale, or hybrid.
Three identical-on-the-surface generational transfers; three very different tax outcomes. The mechanism that produces the divergence is the basis-and-character treatment that applies separately to each transfer type. Gifts of cash transfer no embedded gain because cash has no appreciated basis. Gifts of appreciated property under IRC §1015 transfer the donor’s basis to the recipient, meaning the recipient eventually pays the income tax on the embedded gain when the property is sold. Gifts of business interests under IRC §2701-§2704 introduce valuation considerations that can shift the effective transferred value substantially in either direction. Most coverage of wealth transfer treats “gifting \$100,000” as a generic action; the actual planning depends on which \$100,000 you’re gifting, and from which appreciated-or-not basis pool.
Gifting cash: the simplest transfer
A cash gift from parent to child has clean tax treatment. The gift is not taxable income to the recipient under IRC §102(a). The donor does not recognize gain on the transfer (because cash has no embedded gain). The gift consumes annual exclusion under IRC §2503(b) (\$18,000 per donor per donee for 2024, indexed annually) and, for amounts above the annual exclusion, lifetime exemption under IRC §2010(c). For most middle-and-upper-middle-income transfers, the cash gift fits within the annual exclusion entirely and produces no Form 709 filing requirement.
The structural disadvantage of cash gifting is that it transfers no embedded appreciation. A parent with a \$2M brokerage account holding appreciated securities and a \$200K money-market account who wants to make a \$200K gift to a child has a choice: gift the cash and keep the appreciated securities, or gift the appreciated securities and keep the cash. If the parent gifts the cash and dies later holding the appreciated securities, the children inherit the securities with a stepped-up basis under IRC §1014, the embedded gain disappears for income-tax purposes. If the parent gifts the appreciated securities and dies later holding only cash, the embedded gain has already been transferred to the child under §1015 carryover basis, meaning the child eventually pays income tax on it when the securities are sold.
The basis math typically favors holding appreciated property until death (capturing the §1014 step-up) and gifting cash during life. This is the standard estate-planning sequencing for taxpayers who have both cash and appreciated property available for gifting.
Gifting appreciated stock: the carryover-basis trap
A gift of appreciated property transfers the donor’s basis to the recipient under IRC §1015(a). The recipient takes the donor’s basis (with potential adjustments under §1015(d) for gift tax paid) and uses that basis to compute gain when the property is later sold. The embedded gain is effectively transferred to the recipient along with the property.
A specific exception under §1015(a) applies for property gifted at a loss: if the fair market value at the date of the gift is less than the donor’s basis, the recipient uses FMV (not the donor’s basis) as the basis for computing loss on a later sale. This is the “dual basis” rule, the recipient has one basis for computing gain (the donor’s basis) and a different basis for computing loss (the FMV at gift). The dual-basis rule generally disadvantages the recipient if the property is gifted at a loss and later appreciates only modestly.
For a parent considering whether to gift highly appreciated stock or to hold it until death:
- Gift now: \$100K stock with \$10K basis goes to child; child eventually sells for \$100K and recognizes \$90K gain; income-tax cost to child at typical LTCG rates is \$13,500-\$18,000+ depending on bracket and any §1411 NIIT exposure.
- Hold until death: Same stock receives step-up to date-of-death FMV under §1014; child inherits \$100K stock with \$100K basis; sells for \$100K and recognizes zero gain. The income-tax cost of the embedded appreciation effectively disappears.
The basis math overwhelmingly favors holding-until-death for appreciated property, UNLESS the donor needs the property out of the estate for estate-tax reasons (which becomes more important as estate values approach the lifetime exemption, especially with the post-2025 sunset reducing the exemption).
Gifting business interests: where the valuation rules live
The third category is gifts of interests in closely held businesses, family limited partnerships, S-Corp shares, LLC membership interests, partnership-of-real-estate interests. The fundamental difference from cash or stock gifts is that the gift value is not directly observable. Closely held interests are not publicly traded; the fair market value requires a qualified appraisal under Treas. Reg. §1.170A-13(c) (which applies to charitable contributions and is generally followed for gift-tax valuation purposes).
The qualified-appraisal valuation typically reflects discounts that are not available to liquid securities:
- Lack-of-marketability discount. Closely held interests cannot be sold on a public market; a willing buyer would demand a discount for the illiquidity. Discounts typically range from 15-40% depending on the specific facts.
- Lack-of-control discount. A minority interest in a closely held entity cannot direct distributions, force a sale, or compel management actions; the minority position is worth less than the proportionate share of the entity’s gross value. Discounts typically range from 10-30%.
Combined, valuation discounts of 25-50% are common for minority interests in closely held entities. A gift of a 10% interest in a business with a \$1M stated equity value might be valued for gift-tax purposes at \$500,000-\$750,000, meaning the donor consumes that much (less) of the lifetime exemption for the same proportionate transfer.
The special-valuation rules under IRC §2701-§2704 constrain certain aggressive applications of the discount approach. §2703 disregards buy-sell agreements and similar restrictions that aren’t bona fide business arrangements. §2704 disregards “applicable restrictions” on liquidation rights that exist only in family-controlled entities. These rules are subject to ongoing regulatory and case-law development, and aggressive valuations are examination-vulnerable.
The interaction with the post-2025 estate-exemption sunset
The pre-sunset gifting window (covered in yesterday’s article) interacts with the property-type-of-gift decision. A taxpayer with available lifetime exemption capacity in 2024-2025 should think about WHICH assets to use the exemption on:
- Highly appreciated property is the best candidate for pre-sunset gifting if the goal is removing future appreciation from the estate. The §1015 carryover basis is a real cost (the recipient eventually pays income tax on the gain), but the estate-tax exemption locked in pre-sunset removes the same property from the higher-rate estate-tax exposure.
- Cash is appropriate for direct support of beneficiaries or for funding into trusts that don’t need appreciated property. The estate-tax exemption is consumed identically; the income-tax outcome for the recipient is cleaner.
- Business interests are powerful pre-sunset gifting vehicles because the valuation discounts effectively stretch the exemption, gifting an interest worth \$X to the family unit may consume only \$X × (1 – discount) of the donor’s lifetime exemption.
What to do this year
The right gifting strategy depends on the donor’s facts: total estate value, available lifetime exemption, mix of cash vs appreciated property, presence of closely held business interests, recipient bracket, and the donor’s projected longevity (which affects the §1014 step-up calculation). The decision is not generic; it’s specific to the family’s asset mix and the planning horizon.
Three principles hold consistently:
First, gift the right type of property for the goal. Annual exclusion gifts (\$18K per donor per donee in 2024) work well in cash. Lifetime-exemption-consuming larger gifts should be calibrated to the property type that produces the best after-tax outcome given the family’s asset mix.
Second, document the gift contemporaneously. Form 709 captures the federal reporting; the underlying valuation and the supporting analysis for any discount claimed should be in a file at the time of the gift.
Third, model the §1014 step-up tradeoff explicitly. The decision to gift appreciated property during life forfeits the step-up at death; the decision to hold property until death preserves the step-up but exposes the property to estate-tax computation. Which side of that trade is favored depends on the estate’s relationship to the lifetime exemption and on the recipient’s expected income-tax bracket.
The mechanism is knowable. The optimal answer is calculable. The mistake is treating all gifts as generically equivalent.
