Same Trust, New Taxpayer: Special Needs Trust Taxes Before and After a Parent Dies

A special needs trust is built to protect your loved one’s benefits. It also earns income. That income gets taxed. Who pays that tax can change on the day a parent dies.

The legal side of a special needs trust usually gets careful attention. The tax side can end up waiting until the first trust tax return shows up. Here is how the taxes work across both lifetimes and what a trustee can do before the end of the year.

First, Whose Money Is It?

Special needs trusts come in two main types:

• First-party trust. Holds your loved one’s own money, such as an inheritance they received directly, an injury settlement, or back benefits. When your loved one dies, it must pay back Medicaid from what is left.
• Third-party trust. Holds money from parents, grandparents, or others. It does not have to pay back Medicaid.

That label sets the benefit rules. Taxes turn on a different question: who does the Internal Revenue Service (IRS) treat as the owner of the trust?

First-Party Trusts: Taxed to Your Loved One

A first-party trust is usually written so the IRS treats your loved one as its owner. Tax professionals call this a “grantor trust.” The trust’s income goes on your loved one’s own tax return, at their own tax rates.

If your loved one has little other income, the tax may be small or even zero. Ask the attorney who drafted the trust whether the trustee can pay your loved one’s income tax on trust income.

Third-Party Trusts: Two Lifetimes, Two Taxpayers

If a parent sets up a third-party trust as a revocable trust, meaning the parent can still change it, the IRS treats that parent as the owner. Trust income goes on the parent’s own return.

When the parent dies, the trust can no longer be changed and becomes its own taxpayer. From then on:

• It needs its own tax ID number.
• It files its own tax return (IRS Form 1041).
• If your loved one lives in North Carolina, it also files a state trust return (Form D-407).
• It pays tax at trust tax rates, which climb fast.

The trust is still designed to protect your loved one’s benefits. What changes is the tax picture.

Why Trust Tax Brackets Matter

Trust tax brackets are squeezed into a small range of income. In 2026, the 37% federal rate starts at $16,000 of taxable income for a trust. For a single person, it starts at $640,600.

2026 federal tax rates on income a trust keeps:

• Up to $3,300: 10%
• $3,300 to $11,700: 24%
• $11,700 to $16,000: 35%
• Over $16,000: 37%

Each rate applies only to the income in that range. Gains from selling investments and a 3.8% tax on investment income can add to the bill.

Spending for Your Loved One Can Lower the Tax

When the trust pays for something your loved one needs, like therapy or a new wheelchair, it can move up to that amount of its income to your loved one’s personal tax return rather than the trust’s. Your loved one usually pays a lower rate than the trust would. The trust sends a form called a Schedule K-1 showing the amount.

Keep two things in mind:

• Benefit rules still apply. For Supplemental Security Income (SSI), what matters is how the trust pays, not the tax form. Cash handed to your loved one can reduce SSI. So can paying rent or utilities.
• Needs come first. A distribution should serve your loved one. Saving tax is a bonus, never the reason.

Two Tools Worth Asking About

The qualified disability trust exemption. A trust that meets the IRS definition of a qualified disability trust gets a $5,300 exemption for 2026. That means $5,300 of its income is not taxed. For a trust in the 37% bracket, that saves nearly $2,000 in federal tax. To qualify, the trust must be set up only for a person who was under 65 and has a disability. Every beneficiary must also be found disabled by Social Security for at least part of the year. Ask your tax preparer whether the trust qualifies.

The 65-day rule. A trust can choose to treat payments made in the first 65 days of a year as if they were made the year before. For 2026, plan to make those payments by Friday, March 5, 2027. The rule lets the trustee see the full year’s numbers before deciding.

A Year-End Checklist for Trustees

Think of these as year-end waypoints:

• Ask the trust’s tax preparer for a projection of this year’s income and tax.
• Check gains already taken this year and any year-end payouts from mutual funds the trust owns.
• Plan distributions that meet a real need, either before December 31 or by Friday, March 5, 2027.
• Confirm whether the trust qualifies as a qualified disability trust.
• Ask the tax preparer whether the trust owes an estimated tax payment by January 15, 2027.
• Keep receipts and notes for every distribution.

Planning Across Two Lifetimes

The time to map this out is while you are here. Your trust’s attorney, a certified public accountant (CPA), and your financial planner can work through it together: who will prepare the trust’s return, how investments will be managed with taxes in mind, and how distributions will be planned each year. That way, the trustee who steps in after you inherits a plan instead of a puzzle. If you are still choosing that trustee, see “How to Choose a Trustee for a Special Needs Trust.”
