Generational Wealth Management: 4 Practices for High-Earning W-2 Families

By Kevin Luu, Co-Founder and Chief Learning Officer. Reviewed on 2026-09-30.

Generational wealth management is the work of growing, protecting and handing down a family’s assets so they still help the family a generation later. For a high-earning W-2 household with young children, it comes down to four practices: cut single-stock risk on a schedule, use the tax rules that move money to children efficiently, finish the estate documents that matter while the kids are minors, and write down the reasoning behind each decision so the children inherit judgment along with the money.

This guide is written for California and Washington families earning roughly $750,000 to $3 million, mostly from salary and equity compensation, with children under 12. The numbers below are for 2026 unless labelled otherwise.

What generational wealth means for a first-generation W-2 family

Generational wealth is any asset that outlives the person who built it and keeps working for the next generation: investment accounts, retirement accounts, a home, education savings, life insurance proceeds held in trust. For most families in this income range, it is first-generation wealth. Nobody handed it to you. It came from RSU vests, a medical practice salary or a research career, and it is often concentrated in one employer’s stock and one expensive home.

That shape creates three specific risks. A large share of net worth can fall with one company’s share price. Taxes on salary and stock sales in California are among the highest in the country. And if both parents died tomorrow, the default rules could hand a large sum to an 18-year-old with no say in how it is used. The four practices below address those risks in order.

Practice 1: Reduce employer-stock concentration on a written schedule

Families at large tech and biotech employers often hold a large share of their liquid net worth in one stock, because RSUs keep vesting and selling feels like a tax bill. Diversification is the first generational practice because a portfolio that drops by half in a bad year for one company is hard to rebuild while also paying for childcare, a mortgage and 529 contributions.

RSUs are taxed as wages when the shares are delivered at vest. Shares you then hold for more than a year are long-term holdings, with a cost basis equal to their value at vest. The decision is not whether to sell, but how much to sell each quarter or year, and in which tax year.

Worked example: selling $300,000 of vested shares in California vs Washington

Assumptions (illustrative): married couple filing jointly, $1.2 million of W-2 income, taxable income already above $1 million before the sale. They sell $300,000 of long-held employer shares with a $100,000 cost basis, a $200,000 long-term gain.

California has no lower rate for capital gains, so the gain is taxed like salary (FTB). Washington taxes long-term gains at 7% only above its annual standard deduction, and 9.9% on taxable gains above $1 million (WA DOR). Washington families should also note that the state has enacted a 9.9% income tax on AGI over $1 million starting January 1, 2028 (WA DOR), which may change the timing of sales planned for later years.

The practical takeaway: at this income level a California family pays roughly a third of a long-term gain in whichever year it sells, so waiting rarely saves tax and leaves the concentration in place. Selling a fixed amount on a schedule, written down in advance, removes the guesswork. Our investment risk management work starts with exactly this schedule.

Practice 2: Use the tax rules that move money to children efficiently

Several federal rules are built for passing money down. Families in this bracket rarely use all of them.

• Gift tax annual exclusion. For 2026, each parent (and each grandparent) can give $19,000 per child without using any lifetime exemption, or $38,000 per child for a married couple splitting gifts (Rev. Proc. 2025-32). There is no “UTMA contribution limit”; the same gift tax exclusion applies whether the gift goes to a UTMA, a 529 or directly to the child.
• 529 five-year election. A parent can put up to $95,000 into one child’s 529 in 2026 and treat it as spread over five years, or $190,000 per child for a couple, by filing Form 709 (Form 709 instructions). The election uses that donor’s annual exclusion for the child in each of the five years. For two children that is $380,000 of contributions that start compounding years earlier, with the growth outside the parents’ taxable estate. California gives no state deduction for 529 contributions, but qualified withdrawals are free of California tax.
• Lifetime exemption. The federal estate and gift basic exclusion is $15,000,000 per person for 2026, made permanent by the 2025 tax law and indexed from 2027 (IRS). The often-repeated claim that it drops to about $7 million in 2026 is obsolete.
• Kiddie tax. For 2026, a child’s unearned income above $2,700 is taxed at the parents’ rate (Rev. Proc. 2025-32). Moving a large brokerage account into a child’s name therefore saves little income tax for a family at the 35% or 37% federal bracket. The reason to give is long-term growth for the child, not this year’s tax.

The decision for most families: fund 529s early (the five-year election works best when children are young), keep larger transfers in a trust rather than outright, and let the parents’ own retirement accounts and taxable portfolio carry the rest. See our tax management page for how this fits with RSU and bonus planning.

Practice 3: Finish the estate documents that matter while children are minors

For parents of children under 12, the estate plan is less about estate tax and more about who raises the children and who controls the money. Four items cover most of it.

1. Guardians named in a will. A court appoints the guardian either way; naming one in your will tells the court whom you want. Without it, the court decides with no guidance from you.
2. A revocable living trust that holds the home and taxable accounts, so assets pass under your instructions rather than through a court process.
3. A trust for the children instead of outright gifts. Under California law, a UTMA account passes to the child at 18 by default, at no later than 21 for a lifetime gift that sets a later age, and no later than 25 when set up through a will or trust (Cal. Probate Code §3920.5). In Washington, gifts to a UTMA end at 21 unless the transferor extends to 25 at the start (RCW 11.114.200). A trust can stagger distributions and set conditions. More on what happens when a UTMA ends.
4. Beneficiary designations that match the plan. 401(k)s, IRAs and life insurance pass by beneficiary form, not by will. A minor cannot take control of these directly. See naming a trust as beneficiary.

Washington families: the state estate tax applies at a much lower level

Washington’s estate tax exclusion is $3,000,000 for deaths from July 1 to December 31, 2026 ($3,076,000 for deaths in the first half of the year), with rates starting at 10% (WA DOR). Illustration: a Seattle couple with $2 million of home equity, $3 million of investments and retirement accounts, and $4 million of term life insurance owned by the insured could leave a $9 million estate at the second death. That is far below the federal $15,000,000 exclusion but well above Washington’s. Whether insurance ownership, trust design or lifetime gifts should change is a question for your estate attorney, and it is worth asking now.

Our estate planning work coordinates these documents with the attorney who drafts them.

Practice 4: Write down the reasoning, then review it once a year

When family wealth fails to last, the cause is often not the investments. It is that the next generation received the money without the thinking behind it. As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.”

In practice, that means a short written record for each major decision: why you sold the stock on that schedule, why the trust pays out at 25 and 30 instead of 18, why you chose those guardians, what you believe money is for. A one-page Decision Memo per decision is enough. Families who keep these records in a FamilyKnowledge® Library can hand the children something they can read at 16 and again at 30.

Then review once a year, ideally in the same month: concentration percentage, 529 balances against the plan, beneficiary forms after any job change, and whether the guardians are still the right choice. Our family governance and Age Five Wealth Education services are built around this yearly rhythm.

Common mistakes we see in high-earning households

• Holding vested RSUs to “wait for a better price” while a single stock grows past a third of net worth.
• Opening UTMA accounts for large sums without realizing the child gets control at 18 or 21.
• Updating the will but not the beneficiary forms on a 401(k) or a group life policy.
• Assuming estate tax is irrelevant because of the federal exclusion, while living in Washington.
• Having all the documents in place but no record of why, so the children see the outcome without the reasoning.

Frequently asked questions

Is generational wealth management only for the very rich?

No. A household earning $750,000 or more with a few million in assets already has the problems it addresses: one-stock concentration, high state tax, minor children who would inherit outright, and in Washington a state estate tax on estates above about $3 million (2026). The tools are the same ones larger families use, at a smaller scale.

When should we start teaching our children about the family’s money?

Earlier than most parents think. Young children notice how decisions are made long before they understand the numbers. Start with simple choices and the reasons for them, and keep a written record you can share in more detail as they grow. The documentation matters more than the age you begin.

Next step

Pick one of the four practices and finish it this quarter. For most families that is either a written sale schedule for employer stock or a trust for the children in place of UTMA accounts. If you would like a second set of eyes on the full picture, the Tax & Wealth Assessment from Age Five Family Office™ covers all four.
