Yes, a trust earns interest whenever its assets are invested in anything that pays interest, and it can also earn dividends, rent, and capital gains depending on what it holds. The more useful question is who pays tax on that interest, and the answer turns on what kind of trust it is and whether the money stays inside the trust or gets paid out to a beneficiary.
What Income a Trust Actually Earns
The assets placed into a trust form its principal, sometimes called the corpus, and that principal is meant to be invested. Bonds, Treasury bills, and certificates of deposit generate interest. Stocks produce dividends. Real estate held inside the trust produces rent. When the trustee sells an appreciated asset, the profit is a capital gain.
The mix depends on how the trustee invests. A trust loaded with bonds will throw off interest. One concentrated in equities will produce dividends and gains. Most trusts hold a diversified portfolio and earn some of each.
Who Pays Tax on the Interest a Trust Earns
Trust income doesn’t have a single tax answer. Before anything else, you have to know which type of trust is holding the assets, because the tax treatment is completely different.
Grantor Trusts
The most common trust in estate planning is the revocable living trust, and it is a grantor trust. When the person who created the trust keeps certain powers over it, including the power to revoke it, federal tax law treats all of the trust’s income as the grantor’s personal income.1Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners
In practice, the trust is invisible for income tax purposes while the grantor is alive. Interest, dividends, and gains earned inside the trust get reported on the grantor’s personal Form 1040, not on a separate trust return. The IRS even allows the trustee to use the grantor’s Social Security number for the trust’s accounts, so a separate tax identification number isn’t needed.2Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025)
A revocable trust stays a grantor trust until the grantor dies, gives up the power to revoke, or amends it to remove the triggering powers. At death, it typically becomes irrevocable and converts to a non-grantor trust, which is where the harsher rules below start to bite.
Non-Grantor Trusts
Once a trust is no longer a grantor trust, it becomes its own taxpayer. It files IRS Form 1041 each year and calculates a figure called Distributable Net Income, or DNI.3Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts DNI is the trust’s taxable income with certain adjustments, including the exclusion of capital gains allocated to principal and not distributed.4Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D
DNI acts as a ceiling on distributions. The trust can deduct what it pays out to beneficiaries, but only up to the DNI amount. That deduction shifts tax from the trust to the beneficiaries, who report their share on their personal returns. Each beneficiary who receives a distribution gets a Schedule K-1 from the trust showing their share of income, deductions, and credits.5Internal Revenue Service. Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR
Income the trust keeps gets taxed at the trust’s own rates.
Simple Trusts vs. Complex Trusts
Every non-grantor trust is either simple or complex, and the classification can change year to year. A simple trust must meet three conditions every tax year: the trust document requires all accounting income to be distributed currently, the trust makes no distributions of principal during the year, and the trust makes no charitable contributions.6Office of the Law Revision Counsel. 26 USC 651 – Deduction for Trusts Distributing Current Income Only Break any one of those in a given year and the trust is complex for that year.
Because a simple trust must distribute all income, that income is generally taxed to the beneficiaries at their personal rates. A complex trust can accumulate income, pay out principal, or make charitable contributions.7Office of the Law Revision Counsel. 26 USC 661 – Deduction for Estates and Trusts Accumulating Income or Distributing Corpus Whatever a complex trust accumulates gets taxed inside the trust.
Why Trusts Try Hard Not to Hold Their Interest Income
Trust tax brackets are brutally compressed. For 2026, the federal income tax brackets for estates and trusts are:8Internal Revenue Service. Rev. Proc. 2025-32
- 10% on taxable income up to $3,300
- 24% on $3,301 to $11,700
- 35% on $11,701 to $16,000
- 37% on income over $16,000
A single individual doesn’t hit the 37% rate until taxable income passes roughly $626,000. A trust gets there at $16,000. That is the single most important tax fact about trust income, and it is why competent trustees push income out to beneficiaries in lower brackets instead of letting it pile up inside the trust.
On top of regular income tax, trusts with retained investment income face the 3.8% Net Investment Income Tax. For trusts, the NIIT kicks in once adjusted gross income exceeds the dollar amount where the top regular bracket begins, which is $16,000 for 2026.9Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax It applies to the lesser of the trust’s undistributed net investment income or the excess of AGI over that threshold.10Internal Revenue Service. 2Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025) The extension gives more time to file but not to pay.
Trusts that expect to owe at least $1,000 in tax for the year, after withholding and credits, must make quarterly estimated payments. The 2026 quarterly deadlines are April 15, June 15, September 15, and January 15, 2027.11Internal Revenue Service. Form 1041-ES, Estimated Income Tax for Estates and Trusts Missing a payment triggers an underpayment penalty based on the shortfall, the length of time it was outstanding, and the IRS’s published quarterly interest rate.12Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
A trust can avoid the penalty by paying at least 90% of the current year’s tax liability, or 100% of the prior year’s liability. The safe-harbor figure rises to 110% of the prior year if the trust’s adjusted gross income exceeded $150,000 in that prior year.11Internal Revenue Service. Form 1041-ES, Estimated Income Tax for Estates and Trusts
If the Beneficiary Receives SSI, Watch the Distribution
Trust income affects Supplemental Security Income differently depending on how it’s paid out. Cash paid from a trust directly to an SSI recipient reduces their benefit dollar for dollar. Money paid to a third party for shelter on the beneficiary’s behalf also reduces benefits, though the reduction is capped at $342.33 per month as of 2025. Payments to third parties for other expenses, including medical care, phone bills, and education, do not reduce SSI at all.13Social Security Administration. SSI Spotlight on Trusts
As of late 2024, the Social Security Administration no longer counts food provided by a third party as in-kind support and maintenance, so trust distributions used to buy groceries or pay for meals no longer cut the SSI payment.13Social Security Administration. SSI Spotlight on Trusts Families with a beneficiary on SSI often use a special needs trust designed to hold and distribute assets without jeopardizing benefits. Getting the structure wrong can cost the beneficiary the full monthly payment.
