Multigenerational money planning: gifts, family banks, and intra-family loans

Once a family has more than it needs and relatives who could use help, money starts flowing between generations whether or not anyone plans it — a check for a down payment here, tuition covered there, a loan that everyone pretends isn't a gift. Done casually, this creates tax surprises, resentment, and the occasional IRS problem. Done deliberately, the same transfers can move substantial wealth down the family tree tax-efficiently, keep money working inside the family instead of at a bank, and reinforce rather than erode the relationships involved. This is the machinery wealthy families use, and most of it is available to any family with a surplus and a willingness to do the paperwork.

Annual gifting: the workhorse

The foundation of multigenerational planning is the annual gift tax exclusion — the amount one person can give another each year with no tax filing and no impact on lifetime exemptions. It sits around $18,000-19,000 per recipient per year in recent years, and it's per giver, per recipient. That means a married couple can give $36,000-38,000 to each child, and to each child's spouse, and to each grandchild, every single year, entirely outside the estate. A couple with three married children and six grandchildren can shift over $400,000 a year down the family tree without touching their lifetime exemption or filing a gift tax return. Over a decade, that's millions moved out of a taxable estate, tax-free, while the givers are alive to watch it help.

Intra-family loans: beating the bank, legally

When a family member needs to borrow — for a home, a business, to consolidate high-interest debt — the family can be the lender, and everyone can come out ahead. The IRS requires only that the loan charge at least the Applicable Federal Rate (AFR), a published minimum rate that is typically well below bank and mortgage rates. The borrower pays less than they'd pay a bank; the lender earns more than a savings account, with interest staying inside the family; and because the rate is legitimate, the loan isn't reclassified as a taxable gift. The essential requirement is that it must be a real loan: a signed promissory note, a set rate and term, and actual repayments that happen.

The table shows the quiet power of the structure: on a $300,000 loan, choosing the family as lender instead of a bank saves the borrower roughly $476 a month and keeps every dollar of interest inside the family instead of paying a stranger. The lending parent earns a solid, secured return; the borrowing child gets a below-market rate; and if the parent later chooses to forgive some principal, they can do it in annual-exclusion-sized chunks that double as tax-free gifts.

The family bank: structure over one-off checks

The 'family bank' is less a legal entity than a philosophy: instead of scattered, ad hoc handouts, the family pools a defined amount of capital and lends or grants from it under written rules. It might be an actual account, an LLC, or a trust, but the core idea is governance — a clear process for who can request money, for what purposes, on what terms, and with what expectations of repayment or performance. A family bank might fund business startups as loans, education as grants, and first homes as below-market mortgages, all documented and tracked. The structure does something no individual check can: it treats family capital as a renewable resource to be stewarded rather than a series of favors to be remembered and resented.

Setting it up without wrecking the family

1. 1
   Start with the estate and gift-tax map

   Before moving money, understand your annual exclusion, your lifetime exemption, and your state's rules. A short engagement with an estate attorney and CPA pays for itself the first year and prevents six-figure mistakes.

2. 2
   Document everything like a stranger would

   Every intra-family loan needs a signed promissory note, a stated AFR-or-higher rate, a term, and a real repayment record. Undocumented 'loans' are treated by the IRS as gifts, which can consume your exemption or trigger tax.

3. 3
   Write the rules before the requests

   Decide in advance what gets granted versus loaned, who qualifies, and what happens if someone can't repay. Rules set in the abstract feel fair; rules invented in response to a specific child's request feel like favoritism.

4. 4
   Communicate as a family, in the open

   The transfers that damage families are the secret ones. A family meeting where the structure and its fairness logic are explained does more to preserve relationships than any legal document.

The bottom line

Wealth that moves between generations on purpose does more good and less damage than wealth that leaks out in unplanned checks. Use the annual exclusion relentlessly, pay tuition and medical bills directly, structure loans at the AFR with real paperwork, and if the scale justifies it, govern the whole thing as a family bank with written rules. The tax savings are real and large — but the greater prize is a family where money strengthens the relationships instead of quietly poisoning them. Get the documents right and the conversations open, and the machinery takes care of the rest.
