Gifting Appreciated Stock: Tax Strategy and Basis Rules

When you own stock with a large unrealized gain, gifting it to family or charity often produces a better after-tax outcome than selling—the key is understanding basis carryover and when a direct gift beats a sale-and-gift combination.

The basic principle: basis carryover vs. step-up at death

When you die, your heirs receive property with a stepped-up basis—their cost basis is the fair market value on your date of death, not your original cost. This wipes away all unrealized gains.

But when you gift property during your lifetime, the recipient takes a carryover basis—they inherit your original cost basis, and all your unrealized gain travels with the asset.

This seems to favor waiting until death. However, gift tax and income tax interact in ways that often make lifetime gifting more attractive.

Scenario 1: gift to a family member in a lower tax bracket

Setup: You own $100,000 worth of stock that you bought for $20,000 (a $80,000 unrealized gain). You want to pass it to your adult child.

Option A: Gift now

• Gift tax (on $100,000 FMV): $0 if within your lifetime exemption. No income tax at gift.
• Your child’s cost basis: $20,000.
• If your child sells immediately for $100,000, they owe long-term capital gains tax on the $80,000 gain. At 15% or 20% federal rate, that’s $12,000–$16,000.
• Your child nets: $84,000–$88,000.

Option B: Sell, then gift proceeds

• Your sale: $80,000 long-term capital gain; federal tax at 20% = $16,000 (plus any state tax).
• Net proceeds to gift: $84,000.
• Your child’s cost basis in the $84,000: $84,000 (cash has no unrealized gain).
• Your child can hold or spend with no further tax.
• Your child nets: $84,000.

The outcomes are similar in this case, but the timing of tax differs. Gifting defers tax to your child (who can hold longer or live in a lower-tax state). Selling pays tax immediately.

Option C: Hold until death

• You die owning the stock. Heirs receive step-up basis to $100,000 FMV at death.
• Heirs’ cost basis: $100,000. If they sell at $100,000 (or close to it), zero capital gains tax.
• But if you die with $5 million in assets and the stock represents $100,000 of that, you’ve used up your federal estate tax exemption (now $13.61 million, but lower in future years). A large estate might owe federal estate tax of 40% on the $100,000 = $40,000.
• Heirs net: $60,000.

Here, gifting beats death-and-step-up because the step-up benefit is consumed by estate tax.

Scenario 2: gift to a higher-earning child who will hold long-term

Setup: Same $100,000 stock with $20,000 basis. Your child earns $200,000 and is in a 37% federal bracket (plus 3.8% net investment income tax).

If you gift now:

• Your child has carryover basis of $20,000.
• Your child holds for 5 more years. Stock grows to $150,000.
• Child sells: $130,000 gain (initial $80,000 plus $50,000 new appreciation). Capital gains tax at 20% + 3.8% = $18,733.
• Child nets: $131,267.

If you sell first:

• You pay 20% + 3.8% on the initial $80,000 gain = $19,040.
• You gift the $80,960 proceeds to your child.
• Child’s basis: $80,960. Stock grows to $150,000 (but cost basis is $80,960).
• Child sells: $69,040 gain × 23.8% = $16,430 tax.
• Child nets: $133,570.

Here, selling first saves tax because the initial $80,000 gain is realized at lower capital gains rates before the child can compound further appreciation in higher bracket. Gifting keeps the carryover basis and taxes the larger total gain at the child’s rate.

The outcomes are closer, but the timing and total tax matter—this depends on whether the stock continues appreciating.

Scenario 3: gift to charity

Setup: $100,000 stock with $20,000 basis. You want to donate to a nonprofit.

Option A: Gift stock directly

• You deduct the full fair market value ($100,000) against your income.
• Charity takes ownership and sells immediately (charities pay zero capital gains tax).
• Charity receives $100,000; you deduct $100,000.
• Result: $100,000 to charity, $100,000 deduction to you (worth roughly $37,000 in federal tax savings at 37% rate).

Option B: Sell, then gift proceeds

• You sell stock, pay capital gains tax on $80,000 gain = $16,000 (20%).
• Net proceeds: $84,000.
• You gift $84,000 cash to charity.
• You deduct $84,000.
• Result: $84,000 to charity, $84,000 deduction.

Gifting appreciated stock to charity is a pure win. You avoid the $16,000 capital gains tax and get the full $100,000 deduction. This is the strongest case for gifting appreciated securities.

Gift tax and valuation

When you gift stock, the gift tax is based on the fair market value at the date of the gift—typically the closing price on the stock exchange on that date.

You report the gift on Form 709 (Gift Tax Return) and, if within your lifetime exemption ($13.61 million as of 2024), you owe no tax. The gift simply reduces your remaining exemption.

Gift tax is based on current value, not on your cost basis or unrealized gain. A $100,000 gift is a $100,000 gift for tax purposes, regardless of whether you paid $20,000 or $90,000 for it.

Basis step-up at death: why it matters for timing

If you die holding the appreciated stock, your heirs receive a step-up basis to fair market value on your date of death. All unrealized gain is forgiven.

This is a powerful tax benefit—but only if you have room under the federal estate tax exemption. If your estate exceeds $13.61 million (soon lower), you owe 40% federal estate tax on the excess. The step-up benefit is largely wasted because the estate tax bill swallows the savings.

Wealthy individuals often use lifetime gifting specifically to remove appreciated assets from their taxable estate before they die. This allows heirs to benefit from the step-up on the remaining assets, while the gifted assets are already outside the estate.

Timing within tax years and quarters

Stock values fluctuate. If you’re planning a gift, consider timing:

• Gifting in December, when the stock might be depressed before a year-end rally, locks in a lower FMV for gift tax purposes.
• Conversely, if you plan to sell, selling before a price drop avoids the capital gains tax on further depreciation (though this is market timing, not guaranteed).

Loss harvesting and the wash-sale rule

If your stock is below your original cost (an unrealized loss), gifting it doesn’t help you—you cannot deduct the loss at gift.

However, you could sell the stock to realize the loss for income tax purposes, then gift the proceeds (or repurchase similar stock). This is called tax-loss harvesting. It requires following the wash-sale rule: you cannot repurchase the same stock within 30 days of the sale, or the loss is disallowed.

Recordkeeping and basis tracking

If you gift appreciated stock, maintain clear records:

• Cost basis of the stock you gifted (date acquired, price paid).
• Date of gift and FMV at that date (for Form 709).
• Confirmation to the recipient of the carryover basis, so they know their tax position when they later sell.

Many brokerages track cost basis, but it’s wise to keep independent records, especially for older positions or inherited stock with unclear basis.

Planning checklist

To decide between gifting appreciated stock, selling-and-gifting, and holding to death:

1. Is the recipient in a lower tax bracket? Gifting may defer tax to a lower-rate holder.
2. Will the recipient hold for decades? Long holding periods favor gifting (carryover basis, but time to grow); short holding periods favor selling-first (realize gain in your bracket, then gift proceeds).
3. Is this for a charity? Always gift the stock directly—avoid capital gains tax and take the full deduction.
4. Is your estate large? Gifting now reduces estate tax at death. Holding to death gets step-up but may trigger estate tax.
5. What are current capital gains rates? Higher rates favor gifting; lower rates may favor selling-and-gifting.
