Trust Income Tax Brackets: Why Your Trust Pays 37% Tax on Just $15,650 — and How to Stop It

Most people don't realize their trust could be paying the IRS's top 37% tax rate on just $15,650 of income - while individuals don't hit that same bracket until earning over $600,000. If you've set up a trust to protect your family's legacy, this compressed tax structure could be quietly eroding the wealth you worked so hard to build. Poor trust tax planning can cost families tens of thousands of dollars every year - losses that compound over time.

Here's what makes trust taxation so confusing: sometimes you pay the tax personally, sometimes your beneficiaries pay it, and sometimes the trust itself gets hit with the bill—even when no one withdraws a single dollar. Understanding how these rules work is critical to preserving your legacy.

Understanding Trust Income Tax Brackets: Why the 37% Rate Hits So Fast

In 2025, trusts hit the top 37% federal tax bracket at just $15,650 of taxable income. Add the 3.8% Net Investment Income Tax, and you're looking at over 40% combined. Compare that to individuals, who don't reach the 37% bracket until income exceeds $600,000.

This dramatic compression creates a serious problem for families. A trust earning what seems like modest investment income—say, $50,000 or $80,000 annually—can face effective tax rates normally reserved for millionaires. The result? Wealth that was meant to grow for your children or grandchildren is instead being siphoned away by federal taxes year after year.

Many trustees don't discover this until they file the trust's first tax return and see the bill. By then, opportunities to plan around it have already passed.

How Are Trusts Taxed? It Depends on the Trust Type

Not all trusts face these compressed brackets. The tax treatment depends entirely on how your trust is structured and importantly, whether it's still revocable or has become irrevocable.

Revocable trusts remain transparent for tax purposes. The IRS looks right through them and taxes all income directly to you, the grantor. These trusts are excellent for avoiding probate and maintaining privacy, but they don't provide tax advantages during your lifetime.

Irrevocable trusts are where tax planning becomes both critical and complex. Some can be designed so that you continue paying the taxes personally (even though the assets belong to the trust), which can actually become a powerful wealth transfer tool. Others become completely separate taxpayers - and that's where those brutal compressed brackets take effect.

The distinction between these structures isn't just technical. It determines who pays the tax, at what rates, and ultimately how much of your legacy reaches the next generation versus the IRS.

Why Retaining Income Inside a Trust Costs Your Family Money

Here's the mistake trustees make most often: holding income inside the trust "to be conservative" or "to let it grow."

When a trust that's a separate taxpayer retains income rather than distributing it, that income gets taxed at the trust level at those compressed rates. The difference between retaining and strategically distributing can easily reach five figures annually for a trust with significant investment income.

But distribution decisions aren't simple. You can't just "distribute everything" without considering your beneficiaries' individual tax situations, whether distributions might trigger Medicare premium increases, or how your trust document restricts your options. There's also a complex mechanism called Distributable Net Income that governs how and when income can be shifted from the trust to beneficiaries for tax purposes.

The families who get this right treat distribution planning as an annual strategic decision, not an afterthought at year-end. They model scenarios, coordinate with their advisors, and make intentional choices based on the full financial picture.

Special Situations That Create Additional Complexity

When a Trust Inherits Retirement Accounts

Naming a trust as your IRA or 401(k) beneficiary offers valuable protection and control—but it creates significant tax complications. Inherited IRAs must now be emptied within ten years under current law. How and when those withdrawals happen determines whether your heirs face a manageable tax situation or a devastating lump-sum bill.

There are strategies for coordinating these withdrawals with trust distributions, beneficiary tax brackets, and other planning goals—but they require advance coordination between your estate attorney, CPA, and financial advisor.

Real Estate Held in Trusts

If your home is in a revocable trust or certain types of grantor trusts, you can typically still claim the $250,000/$500,000 primary residence capital gains exclusion when you sell. But if your home ends up in the wrong type of irrevocable trust, that exclusion disappears. A gain that should have been tax-free could suddenly create a six-figure tax bill.

This is why reviewing your trust's structure before making major asset transfers or sales is essential - not after.

The Coordinated Approach That Preserves Family Wealth

Smart trust tax planning isn't about loopholes. It's about using strategies already in the tax code through intentional, coordinated decision-making.

The families who preserve the most wealth:

• Clearly understand what type of trust they have and when its tax status might change

• Review distribution decisions annually, not just at trust creation

• Model different scenarios before taking action

• Coordinate their estate planning attorney, CPA, and financial advisor before major decisions

The difference between a trust that protects your legacy and one that slowly drains it comes down to proactive planning. Trust documents don't manage themselves—they require ongoing strategic attention to work as intended.
