Do Trusts Pay State Income Tax Where the Grantor Lived or the Trustee Lives? (w/Examples) + FAQs

A trust does not automatically pay state income tax where the grantor (creator) lived or where the trustee (manager) currently lives. Instead, a trust’s tax home depends on a messy patchwork of conflicting state laws. The location of the grantor, trustee, beneficiaries, and even the trust’s assets can all give a state the power to tax the trust’s income.

The central problem is that there is no single, nationwide rule that defines a trust’s “residence” for tax purposes. This forces trustees to navigate a minefield of contradictory state statutes, such as New York Tax Law § 605(b)(3) and California Revenue & Taxation Code § 17742. The direct negative consequence is the very real risk of double taxation, where two or more states legally tax the same income in the same year, severely draining the trust’s assets. ¹

This isn’t a small issue; mistakes in trust planning can be financially devastating. While it involves estate taxes, not income taxes, the widely reported estate plan of actor James Gandolfini cost his heirs an estimated $30 million in unnecessary taxes, highlighting the high stakes of getting these rules wrong. ³ With trusts themselves hitting the top 37% federal income tax bracket on income over just $15,650 in 2025, avoiding an extra layer of state tax is critical. ⁴

The Core Players: Grantor, Trustee, and Beneficiary

To understand how trusts are taxed, you first need to know the three key roles involved in every trust. These roles are the foundation upon which all the complex tax rules are built.

The Grantor is the person who creates the trust. They are also sometimes called the “settlor” or “trustor.” The grantor is the one who transfers their property—like cash, stocks, or real estate—into the trust’s ownership.

The Trustee is the person or institution (like a bank) responsible for managing the property inside the trust. The trustee has a “fiduciary duty,” which is the highest standard of care under the law. This means they must act solely in the best interests of the beneficiaries, follow the trust’s instructions, and manage the assets prudently. ⁶

The Beneficiary is the person or entity who will receive the benefit of the trust property. There can be current beneficiaries, who are eligible for distributions now, and remainder beneficiaries, who will receive the assets after the current beneficiaries’ interests end.

The Most Important Tax Question: Is Your Trust a “Grantor” or “Non-Grantor” Trust?

Before you can figure out which state can tax a trust, you must answer one question: who is responsible for paying the federal income tax? The answer depends entirely on whether the trust is classified as a “grantor trust” or a “non-grantor trust” by the IRS. This is the single most important distinction in trust taxation.

What is a Grantor Trust and How is it Taxed?

A grantor trust is a trust where the grantor keeps certain powers over the trust assets, as defined by the Internal Revenue Code. ⁷ For example, a trust is a grantor trust if the grantor has the power to revoke it or the power to swap assets of equal value with the trust. Because the grantor hasn’t fully given up control, the IRS treats the trust as a “disregarded entity.” ⁹

This means the trust is invisible for income tax purposes. All of the trust’s income, deductions, and credits are reported directly on the grantor’s personal Form 1040 tax return. ¹¹ The trust itself doesn’t pay any income tax.

For state tax purposes, this makes things simple. The trust’s income is taxed by the state where the grantor lives. ¹ The location of the trustee or beneficiaries is irrelevant for income tax.

What is a Non-Grantor Trust and Why is it So Complicated?

A non-grantor trust is a trust where the grantor has given up all control and power. It is an independent, separate taxpayer in the eyes of the law. ¹⁵ This is the type of trust that creates the multi-state tax problem.

Because it’s a separate taxpayer, a non-grantor trust must file its own federal income tax return, Form 1041, U.S. Income Tax Return for Estates and Trusts. ¹¹ It is responsible for paying federal income tax on any income it earns and does not distribute to its beneficiaries.

This is where the state tax nightmare begins. Since the trust is its own taxpayer, it must have a state of residence, or “situs,” for tax purposes. But because states have different rules for defining a trust’s residence, a single non-grantor trust can find itself being claimed as a resident by multiple states at once. ¹⁷

The Triggering Event: When a Trustee Decides to Accumulate Income

The entire multi-state tax problem for a non-grantor trust is triggered by a single decision: the choice to accumulate income instead of distributing it. This is managed through a concept called Distributable Net Income (DNI).

DNI is a tax calculation that determines the amount of income a trust can pass through to its beneficiaries. ⁴ When a trust distributes money to a beneficiary, it gets to take an “income distribution deduction” on its tax return. ⁴ The beneficiary then receives a Schedule K-1 from the trust and reports that income on their own personal tax return, paying tax in their state of residence. ⁴

If a trust distributes all of its income, its income distribution deduction usually reduces its taxable income to zero. ⁴ The tax liability flows out entirely to the beneficiaries.

However, if a trustee decides to keep (or accumulate) some or all of the income inside the trust, the trust itself must pay tax on that accumulated income. ¹⁵ This act of accumulation is what forces the trustee to ask: “Which state gets to tax this income?”

The Four Pillars: How States Justify Taxing a Trust

States generally use one or more of four key connections, or “pillars,” to claim a non-grantor trust as a resident and tax its worldwide accumulated income. Understanding these four pillars is the key to diagnosing your trust’s state tax risk.

Pillar 1: The Grantor’s Domicile (The “Forever Tainted” Rule)

Many states, including high-tax states like New York and Illinois, use this as their primary rule. ¹⁴ If the grantor was a resident of that state when the trust became irrevocable, the state claims the right to tax the trust’s income forever. This is true even if the grantor, trustee, and all beneficiaries have long since moved away. ¹⁴

This is often called the “forever tainted” rule because the trust can never wash off the jurisdictional “taint” of its creator’s original home state. This is the strongest and most difficult connection for a trust to break.

Pillar 2: The Trustee’s Residence

A large number of states tax a trust if its trustee resides within their borders. ¹ California is the most well-known example. ²³ If a trust has a California trustee, it is considered a California resident trust.

If there are multiple trustees, California will tax a portion of the trust’s income based on the ratio of California trustees to total trustees. ²⁵ This makes the choice of who you name as trustee a critical tax planning decision.

Pillar 3: The Place of Trust Administration

Some states, like Colorado, base tax residency on where the trust is “administered.” ¹ “Administration” refers to the physical location where the trustee’s work gets done. This includes things like where the trust’s records are kept, where investment decisions are made, and where tax returns are prepared. ¹

Unlike the grantor’s domicile, which is fixed in the past, the place of administration is a flexible factor. A trustee can often move the administration of a trust from a high-tax state to a no-tax state to change its tax home. ¹¹

Pillar 4: The Beneficiary’s Residence

A few states have tried to tax trusts based solely on the residence of a beneficiary. ¹ The logic is that the state provides services and protections to the resident beneficiary, so it should be able to tax the trust that exists for their benefit.

However, this is the weakest of the four pillars. As we will see, the U.S. Supreme Court has placed strict constitutional limits on a state’s ability to tax a trust based only on this connection. ³⁰

State	Taxes Based on Grantor’s Home?	Taxes Based on Trustee’s Home?	Taxes Based on Administration Location?
New York	Yes, if grantor was a resident when trust became irrevocable. ²¹	No (but relevant for an exemption).	No
California	No. ²⁷	Yes, taxes a portion of income based on the number of CA trustees. ¹⁴	No
Illinois	Yes, if grantor was a resident when trust became irrevocable. ³³	No	No
Colorado	No	No	Yes, if the trust is administered in Colorado. ¹
Florida	No (Florida has no state income tax on trusts). ³⁴	No	No
Texas	No (Texas has no state income tax). ⁹	No	No
Nevada	No (Nevada has no state income tax). ³⁷	No	No
South Dakota	No (South Dakota has no state income tax). ³⁹	No	No

Note: This table is a simplified summary. State laws are complex and you should always consult a professional.

The Constitution Steps In: North Carolina v. Kaestner

A state’s power to tax is not absolute. The Due Process Clause of the U.S. Constitution requires a state to have a “minimum connection” (or “nexus”) with a trust before it can tax it. ⁴¹ For decades, states pushed the boundaries of this rule, until the Supreme Court finally weighed in.

The landmark 2019 case was North Carolina Dept. of Revenue v. The Kimberley Rice Kaestner 1992 Family Trust. The facts were very specific: a trust was created in New York by a New York grantor, with a New York trustee. The trust’s assets and administration were all outside of North Carolina. ⁴³

The state’s only connection to the trust was that the beneficiaries lived in North Carolina. Critically, the trustee had absolute discretion over distributions, and the beneficiaries had not received any money and had no legal right to demand any. ³⁰

The Supreme Court ruled unanimously that this was not enough. The Court said that because the beneficiaries had no “possession, control, or enjoyment” of the trust assets, North Carolina was not providing any benefits or protections to the trust that would justify taxing it. ³¹ The mere presence of a potential beneficiary was too “tenuous a link.”

The Kaestner ruling was a major victory for taxpayers. It severely weakened the “beneficiary residence” pillar, confirming that a state cannot tax a trust based solely on the residence of a discretionary beneficiary who has no current rights to the assets. This decision reinforces that the strongest connections for tax purposes are the physical presence and legal control of a trustee or the tangible activities of administration within a state. ³²

Three Common Scenarios: How State Tax Rules Play Out in the Real World

The conflicting state rules create bizarre outcomes. A trust can be taxed everywhere at once, or, with careful planning, nowhere at all. Here are the three most common situations families face.

Scenario 1: The “Forever Tainted” New York Trust

This is the most common trap for trusts created in states like New York, Illinois, or Connecticut. These states follow the grantor’s domicile and will pursue the trust for taxes no matter where it goes.

Situation	Tax Consequence
A grantor, who was a New York resident, created an irrevocable trust in 2010. The grantor has since passed away. The sole trustee and all the beneficiaries now live in Florida, a state with no income tax. The trust’s assets are all in brokerage accounts managed from Florida.	New York will continue to claim the trust as a resident and tax 100% of its accumulated income and capital gains. ²¹ The trust is “forever tainted” by its New York origin. The only way out is to see if it qualifies for New York’s narrow statutory exemption. ¹⁶

Scenario 2: The California “Tax Magnet”

California’s unique rules can pull a trust into its tax net unexpectedly, often just because a family member moves there. California’s tax authority, the Franchise Tax Board, is notoriously aggressive.

Situation	Tax Consequence
A trust was created in Nevada, a no-tax state, with a Nevada bank as the sole trustee. The trust has two beneficiaries who live in Arizona. One of the grantor’s children, who is not a beneficiary, is later added as a co-trustee. That child lives in Los Angeles.	California will now tax a portion of the trust’s income. ²⁵ Because one of the two co-trustees is a California resident, California will claim the right to tax 50% of the trust’s worldwide accumulated income, even though the trust was created in Nevada and its beneficiaries live in Arizona.

Scenario 3: The “Nowhere Trust” Planning Opportunity

Sometimes, the conflict between state laws can be used to a trust’s advantage, creating a situation where no state can legally claim it as a resident for tax on its investment income.

Situation	Tax Consequence
A grantor who lives in Colorado creates an irrevocable trust. Colorado law states that a trust is a resident if it is administered in Colorado. ¹ The grantor appoints a trustee who lives and works in New York. New York law states that a trust is a resident if the grantor was a New York resident when the trust was created. ²¹	The trust may owe no state income tax on its accumulated investment income. Colorado cannot tax the trust because it is not administered there. New York cannot tax the trust because the grantor was not a New York resident. This creates a “nowhere trust” that has no state tax home. ¹⁴

Mistakes to Avoid: The Most Common and Costly Trust Tax Errors

Navigating this area is filled with traps for the unwary. A single misstep can lead to thousands of dollars in unexpected taxes, penalties, and legal fees. Here are the most common mistakes trustees and families make.

Choosing a Trustee in a High-Tax State. Appointing a sibling who lives in California or a friend in New Jersey as trustee without understanding the tax consequences is a classic error. The trustee’s residence can single-handedly create a tax liability that could have been completely avoided by choosing a trustee in a state like Florida, Texas, or Nevada. ⁴⁷
Ignoring a “Forever Tainted” State. Many trustees believe that if they move a trust’s administration and assets out of the grantor’s original high-tax state (like Illinois), they have broken the connection. They stop filing tax returns in that state, only to receive a notice years later for back taxes, penalties, and interest. ⁴⁹
Creating a “Ghost Trust.” This is the most basic mistake of all. A person pays thousands of dollars to an attorney to draft a trust document but then fails to actually transfer their assets into it. ¹³ An unfunded trust is just a worthless pile of paper; it provides no tax benefits and no probate avoidance.
Misclassifying the Trust. An inexperienced trustee might mistakenly file the trust’s income on their personal Form 1040, or treat a non-grantor trust as a grantor trust. ⁵⁰ This can lead to paying the wrong amount of tax and failing to comply with the trust document, exposing the trustee to personal liability.
Failing to Track Beneficiary Moves. A beneficiary moving to a state like California can trigger new tax obligations for the trust. ⁴⁹ A trustee has a duty to track where beneficiaries live and understand the tax implications of their moves.

A Step-by-Step Guide to Federal Form 1041

For a non-grantor trust, the Form 1041 is the central nervous system of its tax compliance. Understanding how this form works is essential for any trustee. While it looks similar to a personal Form 1040, its rules are very different.

Here is a line-by-line breakdown of the most critical parts of Form 1041:

Page 1: Income and Deductions

Lines 1-9 (Income): This is where the trustee reports all the trust’s income for the year. This includes taxable interest, dividends, capital gains, rental income, and business income. ⁵³ This total income is the starting point for all tax calculations.
Lines 10-15a (Deductions): The trust can deduct certain expenses. This includes interest paid on loans, state and local taxes, fiduciary fees (what the trustee is paid), and fees for tax preparation and legal advice. ⁵
Line 18 (Income Distribution Deduction): This is the most important line on the form. The number on this line represents the total income passed from the trust to the beneficiaries. This amount is calculated on Schedule B on the second page of the form. ⁵³
Line 23 (Taxable Income): This is the bottom line. It is the trust’s total income minus all its deductions (including the crucial income distribution deduction). This is the amount of income the trust must pay tax on.

Schedule B: The Income Distribution Deduction

This schedule is where the magic happens for shifting tax liability. It is where Distributable Net Income (DNI) is calculated.

Line 1 (Adjusted Total Income): This starts with the trust’s income before the distribution deduction.
Line 7 (Distributable Net Income – DNI): After a few adjustments, this line shows the maximum amount of income the trust can “pass through” to beneficiaries in a given year. It acts as a ceiling for the income distribution deduction.
Line 9 (Income Required to be Distributed Currently): This applies to “simple trusts” that must distribute all their income each year. ⁵⁴
Line 10 (Other Amounts Paid, Credited, or Otherwise Required to be Distributed): This applies to “complex trusts” where the trustee has discretion over how much to distribute. ⁵⁴
Line 15 (Income Distribution Deduction): The final number from this schedule flows back to Line 18 on the first page. It is generally the lesser of the total distributions made or the DNI.

Schedule K-1: The Beneficiary’s Share

For every beneficiary who receives a distribution of income, the trustee must prepare a Schedule K-1. This form breaks down exactly what kind of income (e.g., interest, dividends, capital gains) the beneficiary received. The beneficiary uses this form to report the income on their personal tax return. ⁴

The entire structure of Form 1041 is designed around one core principle: trust income is taxed once. It is either taxed to the trust (if accumulated) or taxed to the beneficiary (if distributed). The form is the mechanism for directing that tax liability to the correct party.

How to Move a Trust to a Tax-Free State

If a trust is stuck in a high-tax state, it is often possible to move its legal residence, or “situs,” to a more favorable jurisdiction. States like South Dakota, Nevada, Florida, and Delaware have become popular trust havens because they have no state income tax on trusts and offer other benefits like strong asset protection. ¹¹

Moving a trust, a process also known as “migration,” generally involves three main methods:

Changing the Trustee. The most common and straightforward method is to replace the trustee in the high-tax state with a new trustee who lives in the desired no-tax state. ¹¹ The administration of the trust—record-keeping, asset custody, etc.—must also physically move to the new state. ²⁹
Modifying the Trust Document. Some modern trust documents contain a specific clause that allows the trustee or a “trust protector” to change the trust’s governing law and situs to another state. This can often be done with the consent of the beneficiaries and without court approval. ²⁹
Decanting the Trust. “Decanting” is like pouring wine from an old bottle into a new one. It is a powerful legal tool that allows a trustee to transfer all the assets from an old, problematic trust into a brand-new trust created in a more favorable state. ⁵⁶ This is often the best solution for escaping a “forever tainted” state. ⁵⁵

Pros and Cons of Moving a Trust’s Situs
Pros
✅ Eliminate State Income Tax: The primary benefit is potentially saving thousands of dollars each year by moving to a state with no fiduciary income tax.
✅ Better Asset Protection: States like South Dakota and Nevada have some of the strongest laws in the country for protecting trust assets from creditors. ⁴
✅ Modernize an Old Trust: Moving a trust often provides an opportunity to update its terms, add flexibility, and incorporate modern administrative provisions. ⁵⁶
✅ Increased Privacy: Some jurisdictions, like South Dakota, offer superior privacy laws that can keep trust details sealed from the public indefinitely. ⁴⁰
✅ Perpetual Duration: Moving to a state that has abolished the Rule Against Perpetuities allows a trust to last forever, creating a true “dynasty trust.” ⁴⁰

Do’s and Don’ts for Trustees of Multi-State Trusts

Serving as a trustee is a serious legal obligation with personal liability for mistakes. ⁵⁹ For a trust with connections to multiple states, the risks are even higher.

DO:

✅ Conduct an Annual Nexus Review. Once a year, formally document the residency of every trustee, beneficiary, and trust advisor. Also, confirm the location of all real estate and business interests. ³²
✅ Hire Experienced Professionals. Do not rely on your personal accountant unless they have specific expertise in multi-state fiduciary taxation. The rules are unique and complex. ⁴⁹
✅ Keep Meticulous Records. Document everything: every decision, every distribution, every communication. Clear records are your best defense if your actions are ever questioned. ⁶¹
✅ Communicate Proactively with Beneficiaries. Lack of communication is a primary cause of trust litigation. Keep beneficiaries informed about the trust’s status and any major decisions. ⁶²
✅ Understand Source Income. Remember that even if your trust is in a no-tax state, you must still file and pay tax in any state where the trust owns real estate or a business. ⁴⁷

DON’T:

❌ Assume Anything. Don’t assume that because the grantor lived in Texas, the trust is a Texas trust. Don’t assume that because a beneficiary lives in California, the trust must pay California tax. Verify the rules for your specific situation.
❌ Co-mingle Assets. Never mix your personal funds with trust funds. Each trust you manage must have its own separate bank and investment accounts. ¹⁵
❌ Delegate and Disappear. You can hire professionals to help, but you cannot delegate your ultimate responsibility. You must supervise the work of any attorney, accountant, or investment advisor you hire. ¹⁴
❌ Ignore Beneficiary Requests. Beneficiaries have legal rights to information. Responding to their inquiries promptly and transparently can prevent small misunderstandings from escalating into major legal battles. ¹⁵
❌ “Set It and Forget It.” A trust’s tax situation is not static. A trustee moving, a beneficiary moving, or a change in state tax law can all create new liabilities. Trust administration requires ongoing vigilance. ⁶³

Frequently Asked Questions (FAQs)

Yes or No: Can a trust be a resident of two states at once?

Yes. This is a primary cause of double taxation. For example, a trust created by a New York resident with a California trustee could be claimed as a resident by both states under their conflicting laws. 1

Yes or No: If my trust only has a beneficiary in California, does it have to pay California tax?

No. Following the Kaestner Supreme Court case, California cannot tax a trust based solely on a beneficiary’s residence if that beneficiary has no current right to demand distributions from the trust. 31

Yes or No: Does moving a trust to South Dakota guarantee it will pay no state income tax?

No. While South Dakota has no income tax on trusts, the trust will still owe tax to any other state where it has “source income,” such as from a rental property or a local business. 47

Yes or No: Is a revocable living trust subject to these multi-state tax rules?

No. A revocable trust is a “grantor trust.” All its income is reported on the grantor’s personal tax return, so its state tax liability is simply based on where the grantor lives. 11

Yes or No: As a trustee, can I be held personally liable for unpaid state taxes?

Yes. A trustee has a fiduciary duty to comply with all tax laws. If you fail to file and pay taxes correctly, you can be held personally responsible for the resulting taxes, penalties, and interest. 59

Yes or No: Can I just distribute all the income to the beneficiaries to avoid this problem?

Yes. Distributing all income shifts the tax burden to the beneficiaries, who pay tax in their states of residence. This can be a simple solution, but it may violate the grantor’s intent for the trust. 47

Yes or No: Is a “testamentary trust” (one created in a will) treated differently?

Yes, often. Many states automatically consider a testamentary trust to be a resident of the state where the deceased person (the testator) was domiciled at the time of their death. 20

Yes or No: Does the location of the trust’s bank account determine its residence?

No. While the location of assets is a factor, the physical location of a bank or brokerage account is less important than the legal residence of the trustee who controls that account. 1

Yes or No: Is it expensive to move a trust?

Yes. Moving a trust involves legal and accounting fees to ensure the transfer is done correctly and is legally defensible. However, these costs are often far less than the long-term tax savings.

Yes or No: Do I need a lawyer to figure this out?

Yes. The rules are extremely complex and vary by state. Attempting to navigate multi-state trust taxation without an experienced attorney or CPA who specializes in this area is a significant financial risk.
