The Bottom Line: As of 1 January, the OBBBA Tax Law 2026 has made the permanent federal estate tax exemption $15 million per individual, providing a historic opportunity for intergenerational wealth transfer. For US families, using a formal Family Loan Agreement to “seed” the newly launched “Trump Accounts” or fund property acquisitions ensures that early support remains equitable across all heirs while satisfying IRS “arm’s length” requirements.
The OBBBA Era and “Trump Accounts”
The OBBBA Tax Law 2026 (One Big Beautiful Bill Act) has stabilized the US tax code, but it has also introduced new complexities regarding how families move capital. Specifically, the July 2026 launch of “Trump Accounts”—a federal tax-deferred savings vehicle for children—allows parents to contribute up to $5,000 per year for kids born after 2025.
If you are using family wealth to fund these accounts for one grandchild but not another, you are failing your Sibling Fairness Audit. In the 2026 economy, even small imbalances in early seeding can lead to massive equity gaps decades later. Documentation is the only way to ensure these transfers don’t lead to “unintended disinheritance.” Under IRS Gift Tax rules, every transfer must be accounted for to protect your $15M exemption and prevent the IRS from reclassifying loans as gifts.
OBBBA Strategic Lending Comparison
| Provision | 2026 Rule | Sibling Fairness Impact |
| Lifetime Exemption | $15 Million per person | Documentation is required to prove “non-gift” status. |
| SALT Deduction | Capped at $40,400 | Non-grantor trusts (funded by loans) can maximize this. |
| Trump Accounts | $5,000/year cap | Requires a “loan” structure to maintain heir equality. |
Protecting the “Step-Up in Basis” and Renovation Capital
The OBBBA preserves the “Step-up in basis,” the most powerful tool in the American tax system for building generational wealth. By structuring support as a formal family loan instead of a gift, you keep the asset in your estate, ensuring your heirs receive that reset tax basis at your passing. If you simply gift the cash today, you lose this benefit and potentially expose the child to massive capital gains later.
This is especially critical when funding home improvements. If you fund a child’s $100,000 kitchen remodel, documenting it as a loan ensures it doesn’t negatively impact their Debt-to-Income (DTI) limits when they seek traditional refinancing later. It also provides the parent with a “shield” against creditors; if the child faces a lawsuit, that $100,000 is a debt that must be repaid to you, not an asset available for seizure.
