Trust Fund Taxes : Rates, Brackets, and Smart Moves

Trusts can protect your business, lock in a succession plan, and keep assets organized. The surprise comes at tax time, when trust fund taxes hit harder and faster than many owners expect.

Here’s the short version. Trust fund taxes are the rules for how a trust’s income gets taxed. Recently, the brackets are tight, and the top 37% rate can kick in at just $15,650 of income, so timing and distributions matter.

Think of Maria, a small manufacturer who set up a trust to transition ownership to her kids. If she leaves too much income inside the trust, it may face higher tax rates than if she distributed some to beneficiaries.

What Are Trust Fund Taxes? The Basics You Need to Know

Trust fund taxes decide who pays tax on a trust’s income and at what rate. For business owners, the setup you choose can change your annual tax bill, your exit proceeds, and your family’s after-tax cash flow. Here’s how the moving parts work.

Types of Trusts and Their Tax Rules

Trusts fall into two big buckets, and each has its own tax outcome. Get this wrong and you can pay more than you should.

• Revocable trusts: You, the creator, keep control. For income taxes, nothing changes. All income, deductions, and credits flow to your personal return. These are great for probate and control, not for income tax savings.

• Irrevocable trusts: The trust is its own taxpayer. Once funded, you typically cannot change terms or reclaim assets. Income may be taxed to the trust, the grantor, or the beneficiaries, depending on how it is drafted and distributed.

Within those, two tax profiles drive who pays the income tax:

• Grantor trusts: Even if the trust is irrevocable, if grantor powers exist, the IRS treats the grantor as the owner for income tax. The grantor pays the tax at personal rates, which are usually lower than trust rates. This can be a strategic “tax burn” that lets the trust compound faster.

• Complex (non-grantor) trusts: These are separate tax entities. They file Form 1041, pay their own tax on undistributed income, and take a deduction for what they distribute. Distributions carry out taxable income to beneficiaries via K-1s.

Why this matters for business owners:

• Income location: Leaving income inside a complex trust can trigger high trust rates quickly. Distributing income to beneficiaries may cut the bill.

• Sale planning: Some owners use irrevocable non-grantor trusts to manage a sale, shift income, or pair with tools like QSBS Section 1202, charitable remainder trusts, or gifting strategies. The goal is to reduce or defer tax and protect proceeds. Structure and timing decide the outcome.

Example: You gift growth shares of your company to an irrevocable trust years before a sale. If drafted as a grantor trust, you pay the tax while the trust compounds.

If set as a non-grantor trust, the trust may absorb or shift income, but you must watch those compressed brackets.

How Trusts Differ from Personal Tax Brackets

Here’s the catch with trust fund taxes in 2025. Trust tax brackets compress fast, so top rates hit at very low income levels compared to individuals.

Quick comparison for 2025:

Taxpayer	Top Rate	Income Where Top Rate Starts
Trusts and estates	37%	Over $15,650
Single filer	37%	Over $626,350

Trust brackets for 2025:

• $0 to $3,150: 10%

• $3,151 to $11,450: 24%

• $11,451 to $15,650: 35%

• Over $15,650: 37%

What this means for owners:

• Distributions matter: Leaving $50,000 of ordinary income inside a complex trust can push much of it to 37%. Distributing income to a beneficiary in a lower bracket can cut the effective rate.

• Bracket management: Spread gains over years, use installment strategies where appropriate, or time dividends and interest to avoid bunching.

• Entity mix: If your trust owns an S corp or LLC interest, coordinate trust type and distribution policy with your operating agreement and cash needs.

Smart move: Model distributions before year-end. Aim to keep trust taxable income under key thresholds, then decide what the grantor or beneficiaries should pick up.

Trust Fund Tax Rates

Trust fund taxes hit quickly because the brackets are compressed. If your trust holds business cash, rental income, or a stock portfolio, 2025 rates can push more dollars into higher brackets fast.

Here is how the numbers work this year, plus a simple way to pressure test your plan.

Income Tax Brackets for Trusts This Year

Trusts reach the top rate at far lower income than individuals. The brackets are:

• 10% on $0 to $3,150

• 24% on $3,151 to $11,450

• 35% on $11,451 to $15,650

• 37% on income above $15,650

Example, a trust earns $20,000 of ordinary income:

• First $3,150 at 10% = $315

• Next $8,300 at 24% = $1,992

• Next $4,200 at 35% = $1,470

• Remaining $4,350 at 37% = $1,609.50

•  

Total tax is $5,386.50, an effective rate near 26.9%. That is a steep climb on just $20,000 of income.

What to do if your trust holds rental income or dividends:

• Consider distributing enough income to keep the trust in lower brackets.

• Line up expenses and deductions in the same year to avoid bunching.

• Review with your advisor before year end, not in March when options are limited.

Capital Gains Taxes Inside Trusts

Trusts have their own long-term capital gain and qualified dividend brackets:

• 0% up to $3,250

• 15% from $3,251 to $15,900

• 20% above $15,900

• Plus a possible 3.8% net investment income tax on investment income

Selling business stocks or funds inside a trust taps these brackets. The gain stacks on top of other trust income, which can push part of the sale into the 20% bracket, then NIIT on top.

Why timing matters:

• Spreading a large sale across calendar years can keep more gain at 15%.

• Harvest losses before year end to offset gains, then rebalance.

• Use the 65-day rule to treat early-year distributions as prior-year payouts, which can shift income out of the trust’s return when it helps.

Qualified dividends follow the same bracket thresholds as long-term gains. If your trust receives sizable dividends, stack them with planned sales and interest income, then map the tax hit before you act.

Quick checklist to reduce tax drag:

• Map expected gains and dividends by quarter.

• Set a distribution target to hold the trust below key thresholds.

• Pair gains with loss harvesting and fee timing for cleaner results.

Bottom line, trust fund taxes reward planning ahead. Small changes in timing and distributions can cut the bill and keep more cash compounding for your goals.

Strategies to Minimize Trust Fund Taxes for Your Business

Smart planning can lower trust fund taxes, improve cash flow, and speed up growth. The goal is simple, move income to the taxpayer with the lowest rate, while keeping control and asset protection.

Here are proven strategies owners use.

Distribute Income to Beneficiaries Wisely

Non-grantor trusts can deduct what they distribute using the DNI rules. That shifts taxable income from the trust, which has compressed brackets, to beneficiaries who may be in lower brackets.

Example, a family trust owns 20 percent of the family shop and receives $30,000 in dividends. The trustee distributes $20,000 to two college-age children who each have little other income.

The trust deducts the $20,000, the kids report $10,000 each, and the family’s total tax bill drops.

Watch the kiddie tax for minors. Unearned income over the annual threshold can be taxed at the parents’ marginal rate.

This does not kill the strategy, it just means you time distributions and match amounts with each child’s other income and age.

• Why it helps: Cuts high trust rates, builds beneficiary credit histories, and supports a steady wealth transfer plan.

• When to use: Non-grantor trust, beneficiaries in lower brackets, and clean documentation of distributions and K-1s.

• How to protect: Use spendthrift provisions and trustee discretion to keep assets safe while distributing taxable income.

Leverage Grantor Trusts for Tax Advantages

Grantor trusts push the income tax to the creator. You pay the tax from your personal return, which lets the trust assets grow without tax drag inside.

That can be powerful for compounding, funding a startup, or building a buyout war chest.

Sales to a grantor trust are ignored for income tax. A business owner can sell shares to a grantor trust in exchange for a note without a capital gains hit.

You lock in value shifts to the trust while you cover the tax bill, which supercharges growth inside the structure.

There are costs, like legal drafting, valuations, and possible trustee fees. For a scaling venture, the long-term savings often outweigh setup costs, especially when paired with discounts, notes, or life insurance for liquidity.

• Best fits: High-growth equity, founder stock, or pre-exit planning.

• Key wins: No capital gains on the sale to your own grantor trust, faster compounding inside the trust, and better estate outcomes.

• Guardrails: Track cash to pay taxes, maintain grantor powers, and coordinate with your operating agreement.

Maximize Deductions and Plan Ahead

Trusts can deduct ordinary and necessary expenses tied to administration. That includes trustee and accounting fees, investment advisory fees that are unique to trusts, state income taxes paid, and charitable contributions made by the trust when properly documented.

Plan the timing. If you bunch fees, state taxes, and charitable gifts in the same year you expect higher trust income, you can curb the top bracket hit.

Use DNI to decide how much income you distribute by year end, then consider the 65-day rule to treat early-year distributions as prior-year payouts.

For business owners, smart planning cuts taxes and protects assets. You keep liability at the trust level, use distributions to manage brackets, and still support growth.

Action steps:

• Map expected income, gains, and distributions each quarter.

• Prepay state estimates when it helps the trust return.

• Align charitable gifts with high-income years for larger impact.

Why it works:

• You reduce taxable income at the trust level, avoid hitting 37 percent too early, and keep more capital compounding for your next move.

Bottom line, trust fund taxes reward planning and precision. Distribute when it lowers the rate, use grantor status to fuel growth, and stack deductions in the right year.

Conclusion

Trust fund taxes reward owners who plan early. You now know the basics of who gets taxed, how the 2025 brackets compress fast, and the core moves that cut the bill, like smart distributions, grantor status, and well-timed deductions.

Trusts protect assets and support a clean succession, but the wrong tax choices get expensive fast. Take one step today, check your trust’s current income and projected distributions for the year.

Book time with a trusted advisor to review your estate plan, confirm the right trust type for your goals, and map bracket targets. Align your structure with growth, and let taxes support your next move, not stall it.
