A non-grantor trust is taxed as its own separate taxpayer: it files Form 1041, calculates its own taxable income, and either pays federal income tax on income it retains or shifts that income to beneficiaries who report it on their personal returns. The defining feature of non-grantor trust taxation is a compressed rate schedule that reaches the top 37% federal bracket at just $16,000 of taxable income in 2026, which is why trustees typically push income out to beneficiaries rather than accumulate it inside the trust.
The Compressed Trust Tax Brackets
Trust income tax brackets are steep. For 2026, a non-grantor trust pays:
- 10% on taxable income up to $3,300
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% on income over $16,000
An individual single filer doesn’t reach 37% until income exceeds roughly $626,000. A non-grantor trust hits it at $16,000. That compression is the single most important number in trust income tax planning, because it means retained income is almost always taxed harder inside the trust than it would be in a beneficiary’s hands.
The trust does get a personal exemption, but it is minimal. A simple trust — one required to distribute all income currently — gets $300. A complex trust gets $100.1Office of the Law Revision Counsel. 26 USC 642 – Special Rules for Credits and Deductions
How Distributions Shift Tax to Beneficiaries
When a non-grantor trust distributes income during the year, the tax burden generally follows the money. A concept called distributable net income, or DNI, sets the ceiling on both sides of the transaction: DNI is the maximum the trust can deduct for distributions, and it is also the maximum amount of trust income the beneficiaries have to report.
The mechanics work like this. The trust reports all its income on Form 1041.2Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts It takes a distribution deduction for amounts paid to beneficiaries, up to DNI. Each beneficiary receives a Schedule K-1 breaking their share into categories — interest, dividends, capital gains, and other items — and reports those amounts on their personal Form 1040.3Internal Revenue Service. Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR (2025) Beneficiaries pay at their own individual rates, which are nearly always lower than the trust’s.
Income retained above DNI stays taxable to the trust at those compressed rates. This is where most trust-level tax exposure comes from, and why trustees pay close attention to the distribution decision every year.
The 65-Day Election
Trustees often don’t know the trust’s final income figures until well after the tax year ends. The Internal Revenue Code gives them a cushion. Distributions made within the first 65 days of a new tax year can be treated as if they had been made on the last day of the prior year, if the trustee makes the election on the trust’s return for that earlier year.4GovInfo. 26 USC 663 – Special Rules Applicable to Sections 661 and 662
For a calendar-year trust, that means distributions made by March 6, 2027, can count as 2026 distributions. It is one of the most useful tools available to a trustee, because the full-year numbers are visible before the decision has to be made about how much income to push out to beneficiaries.
Net Investment Income Tax on Trusts
On top of regular income tax, a non-grantor trust may owe an additional 3.8% Net Investment Income Tax. It applies to the lesser of the trust’s undistributed net investment income or the amount by which its adjusted gross income exceeds the threshold where the highest trust bracket begins.5Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax For 2026, that threshold is $16,000, the same point where the 37% rate kicks in.
A trust with $50,000 of undistributed investment income would owe NIIT on $34,000, adding $1,292 to its tax bill. Distributing income to beneficiaries before year-end reduces or eliminates the trust-level NIIT, though beneficiaries may then owe their own NIIT if their personal income exceeds $200,000 (single) or $250,000 (married filing jointly).6Internal Revenue Service. Questions and Answers on the Net Investment Income Tax Because individual thresholds are much higher than the trust’s, shifting the income out usually leaves the family with a smaller combined bill.
Qualified Business Income Deduction
A non-grantor trust that receives income from pass-through businesses may qualify for the 20% qualified business income deduction under Section 199A, which was made permanent by the One, Big, Beautiful Bill Act in 2025. The trust computes its own deduction on any retained QBI and passes the appropriate share through to beneficiaries on their K-1s for QBI that was distributed. The income thresholds that limit the deduction for certain service businesses apply to trusts at much lower levels than to individual taxpayers, matching the general pattern of compressed bracket amounts at the trust level.
Filing Deadlines and Penalties
A calendar-year non-grantor trust files Form 1041 by April 15 of the following year.7Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025) A trustee who needs more time can request an automatic five-and-a-half-month extension on Form 7004, pushing the deadline to September 30.8Internal Revenue Service. About Form 7004, Application for Automatic Extension of Time to File Certain Business Income Tax, Information, and Other Returns The extension covers filing, not payment. Estimated tax still has to be paid by April 15.
The failure-to-file penalty is 5% of unpaid tax for each month a return is late, capped at 25%. If the return is more than 60 days late, the minimum penalty is $525 or the total tax due, whichever is less.7Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025) A separate failure-to-pay penalty of 0.5% per month applies to unpaid tax and also caps at 25%.9Internal Revenue Service. Failure to Pay Penalty Both can run at the same time, so a trust that files late and pays late accumulates charges quickly.
State Taxation of Non-Grantor Trusts
Federal tax is only part of the picture. Most states also tax non-grantor trust income, and they use very different rules to decide whether a trust is a “resident” for their purposes. Common factors include where the trustee lives, where the trust is administered, where the grantor lived when the trust was created or became irrevocable, where the beneficiaries live, and where the trust assets are located.
Some states will tax a trust’s entire worldwide income based on a single connection — for example, the grantor having been a resident when the trust became irrevocable — even after the trustee, beneficiaries, and assets have all moved elsewhere. A handful of states have no income tax at all, which is why some trusts are deliberately administered in states like Nevada, South Dakota, or Wyoming. Situs planning is a legitimate tool, but it requires actually meeting the chosen state’s requirements for administration, not simply naming that state in the trust document.
What Qualifies a Trust as Non-Grantor
“Non-grantor” is a tax classification, not a category of trust document. Any irrevocable trust can be a non-grantor trust as long as the grantor has given up enough control that the IRS no longer treats them as the owner for income tax purposes under Internal Revenue Code Sections 671 through 677.10Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners If the grantor keeps a disqualifying power, the trust’s income is taxed on the grantor’s personal return regardless of what the document says, and everything above about Form 1041, DNI, and compressed brackets no longer applies.11Internal Revenue Service.

The powers that block non-grantor status include:
- A reversionary interest in the grantor exceeding 5% of the trust’s value.
- The power in the grantor or a friendly party to decide who receives income or principal, without approval from someone with a competing interest.
- The ability to borrow from the trust without adequate interest, buy trust assets at a discount, or swap property with the trust.
- The power to revoke the trust and take the assets back.
- Trust income that can be paid to the grantor or spouse, used for the grantor’s life insurance premiums, or applied to the grantor’s legal obligations.
Most revocable living trusts are grantor trusts because the power to revoke is one of the clearest disqualifying triggers. Non-grantor trusts are always irrevocable, but not every irrevocable trust is a non-grantor trust — if the grantor retained any of the powers above, the trust is still taxed as a grantor trust and the trust itself pays no income tax.11Internal Revenue Service.
