The Rich Pay Their Kids’ Income Tax Bill Every Year, and the IRS Ruled in 2004 It Isn’t a Gift. The Grantor Trust Rule That Moves Millions Without Touching the $15 Million Exemption
Wealthy parents write six-figure checks to the IRS for income their children never touched, and a 2004 ruling says those payments are not gifts. The legal mechanism behind this move has survived every congressional attempt to shut it down.

Wealthy parents write six-figure checks to the IRS for income their children’s trusts earned, while the kids keep every dollar. The IRS has said since 2004 that these payments are not gifts.
The grantor trust rule and Revenue Ruling 2004-64 let families move millions to heirs over a decade without using any of the $15,000,000 lifetime exemption that applies in 2026.
How a “Defective” Trust Turns a Tax Bill Into a Tax-Free Transfer
The grantor trust rules sit in Sections 671 through 679 of the Internal Revenue Code. If a trust creator keeps certain powers, such as the right to swap assets of equal value back out, the IRS taxes the trust’s income to that person. Estate lawyers intentionally trigger this rule, creating an intentionally defective grantor trust, or IDGT.
The “defect” affects only income tax. For estate and gift tax, the assets have left the parent’s estate and keep growing while the parent pays its tax bill with personal money.
Revenue Ruling 2004-64 says the grantor’s payment of that tax “does not constitute a gift by A to Trust’s beneficiaries for federal gift tax purposes” because the grantor is legally required to pay it. Paying your own bill can’t count as a gift.
Worked Example: $1.11 Million Moved, Zero Exemption Used
A hypothetical couple with over $1 million in other annual income funds an IDGT for their two children with $5 million of stock. Assume the portfolio earns 6% a year, taxed as ordinary income at the 37% rate in 2026.
| Item | Amount |
|---|---|
| Annual trust taxable income | $300,000 |
| Tax the parents pay each year at 37% | $111,000 |
| Gift tax exemption used | $0 |
| Tax the parents pay over 10 years | $1,110,000 |
| Estate tax avoided on that sum at a 40% rate | $444,000 |
The annual gift exclusion is $19,000 per recipient for 2026. Two parents giving to two kids can move $76,000 a year without filing anything against their exemption. The tax payments shift another $111,000 a year on top of that, and the trust’s full return compounds for the children.
The trust escapes its own tax brackets. If it paid its own tax, it would hit the 37% rate at just $16,000 of taxable income in 2026. A single taxpayer doesn’t reach 37% until $640,600, and a married couple filing jointly not until $768,700.
Where the IRS Drew Lines After 2004
Grantor trusts are routine, legal estate planning, but they come with fine print:
- Reimbursement clauses need care. Under the ruling, if the trust must pay the grantor back for the tax, the assets can be pulled back into the grantor’s taxable estate. A trustee’s discretionary power to reimburse can work if state law keeps the grantor’s creditors away from trust assets, per Tax Notes.
- Adding a reimbursement clause later can cost the kids. In Chief Counsel Advice 202352018, released December 29, 2023, the IRS said beneficiaries who agree to add one to an existing trust make a taxable gift.
- Washington has tried to close it. Recent budget proposals would have treated these tax payments as gifts. None became law. The One Big Beautiful Bill made the $15 million per person and $30 million per couple exemption permanent and left the grantor trust rules alone.
In practice, this tool mostly helps families with estates near or above the exemption. The top 1% of households held 32.5% of U.S. net worth as of April 2026, according to the Federal Reserve’s Distributional Financial Accounts.
How Ordinary Families Can Copy the Same Move
Pay a tax bill with your own money so heirs keep the full asset. You don’t need a trust to use this approach.
- Pay Roth conversion taxes from a taxable account. Converting $100,000 in the 22% bracket costs $22,000. Paying that from savings reduces your estate and leaves heirs an account they can withdraw from tax-free. A traditional IRA, by contrast, passes them a tax bill: most non-spouse heirs must empty an inherited IRA within 10 years, paying income tax as they go.
- Pay tuition or medical bills directly to the school or provider. These payments don’t count toward the $19,000 annual exclusion, and there’s no dollar cap.
- Fund a working child’s or grandchild’s Roth IRA. Your contribution counts against the annual exclusion, can’t exceed what the child earned that year, and grows tax-free for decades.
Combining a conversion with a gift plan is math worth running with a fiduciary advisor or CPA before year-end. The grantor trust move is one line item on a much longer estate checklist, and we put the rest of it, beneficiary forms and titling included, in a free report here.
