How Does the Taxation of Trusts Work?
Explore the tax framework for trusts, from the entity's own obligations to the way distributions are passed through and reported by its beneficiaries.
A trust is a legal arrangement where a grantor transfers assets to a trustee to manage for a beneficiary. The trust document details the assets, names the trustee, and identifies the beneficiaries. The trustee has a fiduciary duty to manage the trust’s assets and distributions according to the grantor’s terms. This structure allows for the management of assets like investments, real estate, and business interests.
Identifying the Taxpayer: Grantor vs. Non-Grantor Trusts
The primary question in trust taxation is who is responsible for paying the tax. Trusts are categorized as either grantor or non-grantor, a distinction that dictates whether the tax liability rests with the grantor, the trust itself, or its beneficiaries. This classification is based on the specific powers the grantor retains over the trust’s assets and income as defined in the trust document.
A grantor trust is disregarded for income tax purposes, meaning its financial activity is reported directly by the grantor. All income, deductions, and credits flow through to the grantor’s personal tax return. This occurs because the grantor has not fully relinquished control over the assets. A common example is a revocable trust, which the grantor can amend or revoke at any time; these trusts often use the grantor’s Social Security number as their tax ID.
Several specific powers retained by the grantor can trigger this tax treatment. The power to revoke the trust is the most straightforward example. Other powers include controlling the beneficial enjoyment of the trust’s principal or income, such as deciding who gets distributions. Certain administrative powers, like the ability to borrow from the trust without adequate interest or security, can also result in grantor trust status.
In contrast, a non-grantor trust is a separate taxable entity, which occurs with irrevocable trusts where the grantor has given up control. As a distinct taxpayer, a non-grantor trust must obtain its own tax identification number and file an annual Form 1041, U.S. Income Tax Return for Estates and Trusts. The tax liability for a non-grantor trust falls on the trust itself for any income it retains. If the trust distributes income to its beneficiaries, the tax liability for that income shifts to them.
Calculating Taxable Income for a Non-Grantor Trust
A non-grantor trust calculates its own taxable income. The process begins with determining the trust’s gross income, which includes all income generated by its assets, such as interest, dividends, rent, and capital gains from the sale of assets. This income is reported to the IRS under the trust’s separate tax identification number.
From its gross income, the trust can subtract allowable deductions for expenses incurred in its administration. Common examples include trustee fees, professional fees for services like tax preparation and legal advice, and certain state and local taxes paid by the trust.
A non-grantor trust can take an income distribution deduction for income it distributes to its beneficiaries during the tax year. The purpose of this deduction is to prevent double taxation, ensuring that income is not taxed at both the trust and beneficiary levels. For example, if a trust earns $10,000 in interest and distributes that full amount, it can take a $10,000 deduction, resulting in no taxable income for the trust.
The limit for the income distribution deduction is determined by Distributable Net Income (DNI). DNI sets the ceiling for how much the trust can deduct for distributions. It also determines the amount and character of the income that beneficiaries must report on their personal returns, ensuring they are not taxed on more income than the trust actually earned.
Trust taxation features highly compressed tax brackets, meaning trusts reach the highest federal income tax rate at a much lower income level than individual taxpayers. For example, in 2025, a trust would hit the top 37% tax rate on taxable income over $15,650. This structure incentivizes trustees to distribute income to beneficiaries, who are often in lower personal tax brackets, rather than accumulating it within the trust.
Taxation of Trust Distributions to Beneficiaries
When a non-grantor trust makes a distribution, the tax consequences shift to the beneficiary. The taxation of these distributions is governed by the “conduit principle,” which means the trust acts as a pipeline, and income passed through it retains its original character. For example, if the trust receives tax-exempt municipal bond interest and distributes it, it remains tax-exempt for the beneficiary.
Trusts are often classified as either simple or complex. A simple trust is required by its governing document to distribute all of its income annually. In this case, the beneficiaries are responsible for paying the taxes on that income. Capital gains are typically taxed to the trust, as they are considered an addition to the principal.
A complex trust gives the trustee discretion to either distribute income or accumulate it within the trust. A complex trust can also make distributions from the trust’s principal and make charitable contributions. If income is distributed, the beneficiaries pay the tax; if it is retained, the trust pays the tax on the accumulated amount.
The trustee must provide each beneficiary who receives a distribution with a Schedule K-1 (Form 1041). This document breaks down the specific amounts and types of income they have received from the trust, such as interest income and dividend income. The beneficiary then uses the information from the Schedule K-1 to report their share of the trust’s income on their personal income tax return. Distributions of the trust’s principal are generally not taxable to the beneficiary.
Filing and Reporting Obligations
The trustee of a non-grantor trust is responsible for all tax filing and reporting duties. The trustee must obtain an Employer Identification Number (EIN) from the IRS, which serves as the trust’s tax identifier. The trustee must also maintain records of all income received and all deductible expenses paid throughout the year.
The primary tax form for a non-grantor trust is Form 1041, the U.S. Income Tax Return for Estates and Trusts. This form is used to report the trust’s income, deductions, gains, and losses, and to calculate the tax liability on any income retained by the trust.
The filing deadline for Form 1041 is April 15th, the same as for individual tax returns. If more time is needed, a trustee can file for an extension. The return can be filed by mail or e-filed.
After filing Form 1041, the trustee’s final reporting duty is to the beneficiaries. The trustee must furnish a copy of the completed Schedule K-1 to each beneficiary by the filing deadline. This allows beneficiaries to accurately report the income they received from the trust on their own tax returns.
