Building Wealth That Lasts Across Generations

There is an old saying, found in many languages, that family wealth goes "from shirtsleeves to shirtsleeves in three generations": one generation builds it, the next keeps it, the third spends it. The saying survives because the pattern is real, and the cause is rarely a bad investment. More often the money passes down but the knowledge, habits and trust that built it do not. This chapter covers what lasting family wealth is made of, the accounts and documents that pass it on efficiently, how to raise children who can handle money, and how to talk about it as a family.

Three kinds of family capital

Money is only one of the things a family passes on.

Financial capital is what most people mean by wealth: savings, investments, a home, a business.

Human capital is the knowledge and skills of each family member: their earning power, their financial literacy, their judgment. A child who knows how to budget, invest and avoid high-interest debt is worth more to the family's future than a larger inheritance handed to someone who does not.

Social capital is the family's ability to talk, decide and stay on good terms when money is involved: shared values, clear communication, and an agreed way to settle disagreements. Families rarely fall out over investment returns. They fall out over surprises, unequal treatment and decisions made without explanation.

A plan that builds only the first kind tends to lose it. The rest of this chapter covers all three.

Accounts that work across generations

Some accounts are especially useful when the horizon is longer than one lifetime.

Roth IRAs. The original owner never has to take required minimum distributions, so the account can keep growing tax-free. Most heirs other than a spouse must empty an inherited Roth IRA within ten years, but qualified withdrawals remain tax-free.

529 plans. The beneficiary can be changed to another family member, so money not needed by one child can pass to a sibling, a cousin or a grandchild, and limited amounts can move to the beneficiary's Roth IRA (chapter 6).

Taxable investments held for life. Under current federal law, most assets inherited at death receive a "step-up" in cost basis to their value on the date of death, so gains that built up during the owner's life are not taxed as income to the heir. This is one reason long-held, low-cost index funds are a common core for family wealth.

A home or a business can also carry across generations, but both need a plan: who will own it, who will run it, and how siblings who do not take it are treated fairly.

Gifts during your life can move money efficiently too. In 2026 each person can give up to $19,000 to each of any number of recipients without using any of their lifetime exemption or filing a gift tax return. A married couple can each give that amount to the same person. Contributions to a 529 plan count as gifts, and a special election lets a donor spread a large 529 contribution over five years of exclusions.

Raising children who can handle money

Financial education works best when it is early, regular and practical, with real money and decisions that have small consequences.

A Roth IRA for a teenager is one of the most powerful tools on this list. It requires earned income, and contributions cannot exceed what the teen earned that year, but a parent or grandparent can give the money to make the contribution as long as the teen earned at least that much. Time does the rest. A single contribution of $3,000 made at 16 and left alone until retirement:

Over 45 years at an assumed 7.0% a year, that one contribution grows to about $63,007. Now suppose the same teen contributes $250 a month through five years of summer and part-time jobs:

The account would hold about $17,799 before the teen has even started a career, with four decades of compounding still ahead.

What tends to work: real money and real choices, letting mistakes happen while the stakes are small, talking about the family's finances in a way suited to the child's age, and modelling the habits you want them to copy. What tends not to: shielding children from every financial reality, rescuing every mistake, or leaving the first real conversation until an inheritance arrives.

The documents every adult needs

Estate planning is not only for the wealthy. Every adult needs a few basic documents, and parents of young children need them most.

• A will, which says who receives what and, for parents, who would raise minor children.
• A health care directive, which names who makes medical decisions if you cannot and records your wishes.
• A durable financial power of attorney, which names who manages your money if you are incapacitated.
• Up-to-date beneficiary designations on every retirement account, life insurance policy and bank account that allows one. These usually override a will, so an old form naming a former spouse can send the money to the wrong person.

Families with more assets, property in several states, a business, or a child with special needs often add a revocable living trust, which can avoid probate and keep the details private. Federal estate tax applies only to estates above $15,000,000 per person for deaths in 2026, so it affects very few families, but some states levy their own estate or inheritance tax at much lower levels. The estate tax calculator shows the federal picture, and the life insurance needs calculator estimates how much coverage would replace an income for the people who depend on it. An estate attorney can draft documents that fit your state's law.

Talking about money as a family

Money is often the subject families avoid most, and silence is what turns an inheritance into a dispute. A simple rhythm helps.

Once a year, a family money meeting. Share the broad picture at a level suited to everyone present: what the family values, what it is saving for, what it gives to, and where the important documents are. Include children in an age-appropriate way.

With adult children, occasional updates on the estate plan and any major decisions, so nothing important arrives as a surprise.

At life events, such as a marriage, a birth, a career change or a health diagnosis, a conversation about what changes.

Write down the essentials: where accounts are held, who your advisers are, where the will and directives are kept. A one-page "if something happens" letter saves the people you leave behind weeks of searching.
