Last month a client called to tell me his financial advisor had suggested he gift his three adult children $300,000 each in Apple stock — representing shares he had bought in 2005 for about $10,000 each and were now worth $900,000 total. "He said the kids are in lower tax brackets, so they can sell more efficiently than I can."
His financial advisor is an experienced, credentialed professional at a well-known firm. He was also, in this case, about to cost the family roughly $178,000 in unnecessary federal capital-gains tax.
The Two Rules That Decide This
The difference between gifting appreciated property during life and holding it until death is one of the most consequential decisions in estate planning, and it turns on two rules in the Internal Revenue Code.
Internal Revenue Code Section 1015 — the carryover basis rule for lifetime gifts. When you give appreciated property to someone during your life, they take your original cost basis. My client's basis in those shares is about $10,000. His children's basis, after the gift, would also be $10,000. If they sold the shares immediately at $900,000, their long-term capital-gains tax would be approximately $178,000 at a combined federal rate of 23.8% (20% long-term capital-gains plus 3.8% net investment income tax).
Internal Revenue Code Section 1014 — the step-up in basis at death. When you hold appreciated property until your death, the property receives a new tax basis equal to its fair market value on the date of death. Your heirs inherit with that new basis. If my client had held those same shares until his death and his children sold them the next day for $900,000, their gain would be zero. Their tax would be zero.
Same asset. Same end value. Same family. $178,000 difference, entirely because of timing and structure.
Why the "Lower Bracket" Logic Fails
The financial advisor's reasoning — "the kids are in lower brackets" — is not wrong in every situation. For an asset with very little appreciation, or a regular-income-generating asset, a lifetime gift to a lower-bracket recipient can save tax. The reasoning fails for highly appreciated assets because the step-up is so powerful that it dwarfs any bracket-rate difference.
An asset with $890,000 of built-in gain generates $178,000 of federal tax at the 23.8% rate — in any bracket in which the recipient is meaningfully wealthy enough to be sold stock. The step-up eliminates that $178,000 entirely. No bracket-rate optimization gets anywhere close to that magnitude of savings.
The Texas Community-Property Advantage
For married Texas couples, the step-up is even more powerful. Most jointly owned marital property in Texas is community property, and both halves — the deceased spouse's half and the surviving spouse's half — generally step up at the first death. In a common-law state, only the deceased spouse's half steps up.
For a Texas married couple sitting on $2 million of unrealized gain in a community-property brokerage account, the first-spouse death can eliminate $2 million of gain — versus $1 million in a common-law state. This is why the characterization of property as community vs. separate is so consequential in Texas, and why properly maintaining community-property treatment through the marriage (or converting separate to community via a valid partition or conversion agreement) is a tax-planning act, not a paperwork act.
What to Gift During Life, What to Hold
The planning rule of thumb: gift what you do not need to step up.
- Cash: ideal for lifetime gifts. Basis is already face value.
- High-basis, low-appreciation assets: fine for lifetime gifts. Not much step-up to lose.
- Low-basis, high-appreciation assets (stock, real estate, crypto): hold until death. Do not gift during life unless estate-tax planning specifically calls for it.
- Assets you expect to depreciate: consider harvesting losses during life instead of gifting or holding.
When Gifting Highly Appreciated Assets Is Right
There is one scenario where gifting appreciated assets during life is correct: when the estate is large enough that federal estate tax will consume more than the capital-gains tax saved by the step-up. A family with a $50 million estate facing a 40% federal estate-tax rate is in a different calculus than a family with an $8 million estate that will pass free of federal estate tax either way. For the large-estate family, sophisticated gifting — through GRATs, IDGTs, SLATs, or installment sales to grantor trusts — may be worthwhile even at the cost of the step-up. For most Texas families, it is not.
The right planner asks the right question, which is not "how do I give the kids the most?" but "how does the family pay the least tax in total, across both my generation and theirs?" The answer almost always involves a more patient, less generous-in-the-moment, more tax-efficient-across-generations strategy. Your financial advisor may not be thinking in those terms. Your estate planning attorney should be.
