Most families plan to pass wealth to the next generation.
Far fewer plan how.
The difference shows up in two very specific places: the decision of when to transfer assets, and the decision of whether to wait.
The step-up basis mistake
The most well-intentioned wealth transfer mistake I see is gifting appreciated property to children before death.
It feels generous. It is actually expensive for them.
When you gift an asset during your lifetime, the recipient inherits your original cost basis. If you bought a property decades ago for $100,000 and it is worth $800,000 today, you have handed them a $700,000 taxable gain the moment they sell.
If they inherit that same property after your death, they receive it at a stepped-up basis, the value at time of death. The embedded gain largely disappears.
The best gift, in many cases, is patience. Keep the appreciated asset. Make sure the estate is in order. Let the step-up do the work that a lifetime transfer would undo.
This is not a corner case. It is one of the most common and costly misunderstandings in family wealth planning.
The warm hands principle
The second conversation is the one most families avoid: what to give now, while you can watch it land.
Bill Perkins calls it giving with warm hands. A dollar given to your 28-year-old when they are buying their first home, starting a business, or raising young children hits differently than the same dollar inherited at 55. The timing changes the impact entirely.
The IRS gives you a clean mechanism for this. In 2026, the annual gift tax exclusion is $19,000 per recipient, per year. That means you can give $19,000 to your son, $19,000 to his wife, $19,000 to each grandchild -- all in the same year, all without filing a gift tax return. A couple can double that. The multiplier effect across a family is significant.
Anything above $19,000 per recipient in a given year does not trigger a tax automatically. It just requires filing IRS Form 709 and drawing down against your lifetime exemption. It is paperwork, not a penalty.
The goal is not to maximize what you transfer on paper. It is to make the transfer matter. A well-timed gift, structured correctly, can do more for the next generation than a much larger inheritance that arrives too late to change anything.
What most families are missing
These two ideas, the step-up basis and the annual exclusion, are not complicated in isolation. The hard part is seeing them together as a strategy rather than two unrelated tax rules.
The family that understands both can make very intentional choices: hold appreciated assets until death, gift cash and liquid assets now while the exclusion is available, and structure the whole thing around the moments in the next generation's life where the money actually changes the trajectory.
That is the conversation worth having. Not just what to leave behind, but how to make it count while you are still around to see it.
