Trusts are taxed differently than individuals, and the difference is not subtle. In 2024, a trust reaches the highest federal income tax bracket of 37% at just $14,450 in taxable income. An individual does not hit that same bracket until $609,350. That means a trust pays the maximum rate on income that would barely register on a personal return.
This compressed tax schedule exists because Congress did not want wealthy families parking income inside trusts to avoid individual tax rates. The result is a system where trust income retained inside the trust is taxed more aggressively than almost any other entity. Understanding this dynamic is not optional for effective trust administration. It is the foundation of every tax planning decision you will make.
"I have seen families lose more money to avoidable taxes than to bad investments, lawsuits, and poor planning combined. The reason is simple: nobody taught them the rules."
The most powerful tax optimization tool available to trust administrators is also the simplest: distributing income to beneficiaries. When a trust distributes income, the trust takes a deduction and the beneficiary reports the income on their personal return. If the beneficiary is in a lower tax bracket than the trust, the family's total tax bill decreases.
A trust earns $50,000 in ordinary income. If retained, the trust pays approximately $15,650 in federal income tax (37% on most of that income). If instead the trust distributes $50,000 to a beneficiary in the 22% bracket, the beneficiary pays approximately $11,000. The family saves $4,650 in federal taxes on one year's income. Over a decade, that savings compounds significantly.
The savings become even larger when you account for the 3.8% net investment income tax (NIIT) that applies to trusts at the same compressed thresholds. A trust pays NIIT on all undistributed net investment income above $14,450. A single beneficiary does not pay NIIT until their modified adjusted gross income exceeds $200,000 ($250,000 for married couples).
If the trust is classified as a grantor trust for income tax purposes, the grantor reports all trust income on their personal return regardless of distributions. The trust itself does not file a separate income tax return (though it may file an informational return). This is a critical distinction. Many revocable trusts and certain irrevocable trusts, including intentionally defective grantor trusts (IDGTs), are grantor trusts. The income shifting strategies in this module apply to non-grantor trusts, where the trust is a separate taxpayer.
The timing of distributions matters as much as the amount. Trust income is reported on a calendar year basis, and the trustee has until the 65th day after year-end (March 6 in most years) to make distributions that are treated as if they were made in the prior tax year. This is known as the 65-day rule under Section 663(b) of the Internal Revenue Code.
The 65-day rule is one of the most valuable planning tools in trust taxation. Without it, the trustee would have to guess at year-end income totals and make distribution decisions before the final numbers are known. With it, the trustee can wait until January or February, review the trust's actual income for the prior year, and then make distributions that optimize the overall tax result.
Effective trust tax planning happens in the fourth quarter, not in April. By November, the trustee should have a reasonable estimate of the trust's total income for the year. Working with the trust's CPA, the trustee can model different distribution scenarios and identify the optimal combination of retained and distributed income. The goal is to minimize the family's combined tax bill, not just the trust's.
Where a trust is administered can have a dramatic impact on state income taxes. Some states impose income tax on trusts based on where the grantor lived, where the trustee is located, where the beneficiaries reside, or where the trust is administered. Other states impose no income tax on trust income at all.
South Dakota, Nevada, Alaska, Wyoming, and several other states impose no state income tax on trust income. For a trust earning $200,000 annually in a state with a 10% income tax rate, moving the trust situs to a no-tax state saves $20,000 per year. Over the life of a dynasty trust designed to last for generations, those savings are transformative.
This is one of the primary reasons South Dakota has become the trust capital of America, with over $600 billion in trust assets under administration. The combination of no state income tax, perpetual trust duration, strong asset protection, and favorable trust laws makes it the preferred jurisdiction for sophisticated trust planning.
Many trusts include provisions allowing the trust protector or trustee to change the trust's governing law and situs. This flexibility is essential for long-term tax planning. A trust created in California today might benefit from moving to South Dakota in twenty years if the state tax environment changes. The trust protector provision, discussed in Module 5 on Trust Modifications, is the mechanism that makes this possible.
"Every dollar you save in taxes is a dollar that stays in your family, that compounds over time, that funds an education or starts a business or puts a down payment on a home for the next generation."
One of the most powerful and misunderstood tax rules in estate planning is the step-up in basis under Section 1014 of the Internal Revenue Code. When you hold appreciated assets until death, your heirs inherit those assets at their current market value, not your original cost. The entire unrealized gain is erased.
This has direct implications for trust tax planning. Assets held in a revocable trust receive a full step-up at the grantor's death because the trust assets are included in the grantor's taxable estate. Assets held in certain irrevocable non-grantor trusts may lose the step-up benefit, depending on the trust structure. The planning rule is straightforward: gift cash and low-basis assets to irrevocable trusts where you need estate tax reduction. Hold highly appreciated assets in your revocable trust or personal name where you want the step-up at death.
Coordination between estate tax planning and income tax planning is essential. Your attorney and CPA should work together on these decisions, because the wrong structure can cost your family hundreds of thousands of dollars in unnecessary taxes.
