Family Asset Management: A Guide for High-Income Parents

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

Family asset management is the work of running everything a household owns as one system: the accounts, the equity compensation, the home, the insurance, how each asset is titled and who inherits it. It is broader than investment management, which only covers how a portfolio is invested. For a two-income family earning $750,000 or more with RSUs and young children, the decisions that move the outcome are usually concentration in employer stock, tax treatment, and estate paperwork, not fund selection.

This guide covers how family asset management differs from investment, asset and wealth management, a worked example for a $1.1 million household in California, how the same family looks in Washington, and what to write down so your kids understand the reasoning later.

Family asset management vs investment management, asset management and wealth management

The terms overlap, and the industry uses them loosely. Here is how they differ in practice for a household.

The practical difference: an investment manager can run a good brokerage account while your largest risk sits elsewhere, for example in unvested RSUs at the company that also pays both your salaries, or in a 401(k) whose beneficiary form still names someone from before your kids were born. Accounts held at your employer’s plan or a stock-plan platform are often called held-away assets, and they are where gaps tend to hide. If you want the narrower distinction between the people who run funds, see asset manager vs fund manager.

Step 1: Build one asset map for the whole household

Start with a single table that lists every asset and debt with five columns: value, owner, tax treatment, beneficiary or title, and who makes decisions about it. The list is usually longer than expected once you count both spouses’ workplace plans, old 401(k)s, stock-plan accounts, HSAs, 529s and bank accounts.

Worked example: a $1.1 million W-2 household in the Bay Area

Assumptions (illustrative): married couple filing jointly, ages 41 and 39, children ages 4 and 8. Combined salary and bonus of $700,000, plus $400,000 of RSUs vesting in 2026, for $1.1 million of W-2 income. One spouse works at a large public tech company; the other is a physician.

Two things show up only when everything is on one page. First, investable assets outside the home and 529s total $2,210,000, and $450,000 of that (about 20%) is one company’s stock. Add the $900,000 of unvested RSUs and the employer’s share rises to about 43% of $3,110,000, on top of one spouse’s paycheck. Second, the net worth of $3.63 million is already relevant for estate planning in Washington (see below), even though it is far below the federal exemption.

Step 2: Decide how much single-company stock the family will hold

RSUs are taxed as wages when shares are delivered at vest, so holding vested shares is the same decision as taking cash and buying your employer’s stock. Many families never make that decision on purpose; shares simply accumulate. A written rule (for example, “sell at vest and keep no more than 10% of investable assets in employer stock”) turns a recurring judgment call into a standing instruction.

Withholding is the second issue. For 2026, employers can withhold federal tax on RSU income at a flat 22% supplemental rate, rising to 37% only on supplemental wages over $1,000,000 in the year (IRS Publication 15). In the example, taxable income lands above the 2026 joint 37% threshold of $768,700, so the whole $400,000 vest falls in the 35% and 37% brackets. Withholding at 22% collects $88,000; tax at 35% to 37% on that income is $140,000 to $148,000. That leaves a federal shortfall of roughly $52,000 to $60,000 before California tax, which needs to be covered by estimated payments or extra withholding.

Our investment and risk management work starts with this concentration question because it usually carries more risk than any choice between index funds.

Step 3: Assign each dollar of savings to the right account

At this income, the order in which savings fill accounts matters more than the funds inside them. For 2026 the main limits are:

• 401(k) or 403(b) employee deferral: $24,500 per person (IRS Notice 2025-67).
• Total annual additions to a 401(k), including employer and after-tax money: $72,000 per person. If the plan allows after-tax contributions with in-plan conversion, the room left over is the mega backdoor Roth. With $24,500 of deferrals and a $10,000 employer match, that is $37,500.
• IRA contribution: $7,500 per person. The 2026 joint Roth IRA income phase-out is $242,000 to $252,000, so this household uses the backdoor route (non-deductible contribution, then conversion).
• Dependent care FSA: $7,500 per household, up from $5,000, if the employer’s plan has adopted the new limit.
• HSA family limit: $8,750, with a qualifying high-deductible plan (Rev. Proc. 2025-19).
• Gift tax annual exclusion: $19,000 per donor per recipient, so a couple can put $38,000 per child into a 529 in 2026 without filing a gift tax return when each spouse gives $19,000 (electing to split one spouse’s larger gift requires Form 709). Each donor can also contribute up to $95,000 per child at once and elect on Form 709 to treat it as made over five years (Rev. Proc. 2025-32).

Where investments sit also matters more in California than in most states, because California taxes all capital gains as ordinary income (FTB). Holding the least tax-efficient assets in pre-tax and Roth accounts, and the most tax-efficient ones in the taxable account, is often worth reviewing each year. The tax management side of family asset management is where this coordination happens.

Step 4: How the same family looks in California and in Washington

California. Using the 2025 schedules (2026 schedules were not yet published by the FTB), joint taxable income around $1 million falls in the 11.3% bracket, and taxable income over $1,000,000 adds the 1% Behavioral Health Services Tax, for a 13.3% top rate (FTB 2025 rate schedules). State disability insurance is withheld at 1.3% of all wages for 2026 with no cap (EDD). Selling $450,000 of low-basis employer stock adds the gain to ordinary income for California purposes.

Washington. There is no tax on wages in 2026, but a 9.9% income tax on AGI over $1,000,000 takes effect January 1, 2028 (WA DOR), which this household would likely reach. Long-term capital gains above the standard deduction ($278,000 for 2025, the latest published) are taxed at 7%, and at 9.9% on taxable gains above $1,000,000 (WA DOR capital gains tax). The bigger surprise is estate tax: Washington’s exclusion is $3,000,000 for deaths from July 1 to December 31, 2026 (WA DOR estate tax tables). This family’s $3.63 million net worth is already above it, while the federal basic exclusion is $15,000,000 per person for 2026.

Step 5: Line up titles, beneficiaries and guardians with the plan

Retirement accounts, HSAs and life insurance pass by beneficiary form, not by your will. A family asset map should show, for each account, the named primary and contingent beneficiary. Common gaps for parents of young children:

• No guardian named in a will for children under 18.
• Minor children named directly as beneficiaries. A minor cannot manage the money directly, so a court-supervised guardianship or a custodian may be needed. Naming a trust for the children is a common alternative.
• Assets left outright to a child at a young age. Under California law, a custodial (UTMA) gift transfers at 18 by default, up to 21 if the lifetime gift says so, and up to 25 if made through a will or trust (Cal. Probate Code §3920.5). Washington’s rules differ by transfer type, with up to age 25 allowed if set at the start (RCW 11.114.200).
• A revocable trust that exists but was never funded, so the house and brokerage account still sit outside it.

Our estate planning review checks each line of the asset map against the will and trust documents.

Step 6: Decide what to delegate and how you will pay for it

Busy dual-career parents rarely lack information. They lack hours. Private asset management, in the household sense, means handing the coordination to someone who sees the whole map and is accountable for keeping it current. Before you delegate, check three things: whether the adviser is a fiduciary on every account, how they are paid (flat fee, percentage of assets, or commissions), and whether their scope includes equity compensation, tax coordination and estate documents or only the portfolio. A passive, low-cost portfolio is a reasonable default for many families; the value of help is usually in the coordination, not in picking investments.

Common mistakes in family asset management

1. Tracking only the brokerage account, while 401(k)s, stock-plan accounts and 529s sit unreviewed.
2. Letting vested RSUs accumulate without a written sell rule.
3. Assuming 22% withholding covers the tax on RSU income.
4. Updating the will after a second child but not the beneficiary forms.
5. In Washington, assuming estate tax only applies to very large estates.
6. Keeping the whole picture in one parent’s head, so the other parent, and later the kids, cannot follow it.

What to document for your children

The asset map tells your family what you own. It does not tell them why. Record the reasoning behind the decisions that shaped it: why you sell RSUs at vest, why you chose a trust over leaving money outright, how much you decided to save for each child’s education and what you expect them to contribute. A one-page note per major decision, reviewed once a year, is enough. As Kevin Luu puts it: “Your kids don’t need to inherit your portfolio. They need to inherit your decision-making process.” Our family governance work and the FamilyKnowledge® System are built around this kind of record.

Frequently asked questions

What is family asset management?

It is managing all of a household’s assets and debts as one balance sheet: investment accounts, workplace plans, equity compensation, real estate, insurance and education savings, plus how each is titled and who inherits it. The goal is that every account supports the same plan, and that the reasoning is written down so the other spouse and, eventually, the children can follow it.

Is asset management the same as wealth management?

Not quite. In the financial industry, asset management usually means running investment portfolios, often pooled funds. Wealth management adds tax, retirement, insurance and estate coordination around the portfolio. Family asset management is closest to wealth management, applied to the whole household, including assets held at employers and stock-plan platforms.

How often should a family update its asset map?

Once a year is a reasonable baseline, plus after any major event: a new child, a job change, a large RSU grant or vest, a home purchase, a move between states, or a new will or trust. Each update is a chance to check beneficiaries, concentration in employer stock and whether savings still flow to the right accounts.
