Taxes on a trust inheritance usually come down to three separate questions, not one. The principal you receive is generally not taxed as income under federal law.1Office of the Law Revision Counsel. 26 USC 102 – Gifts and Inheritances Any income those assets produce after you inherit — dividends, interest, rent, capital gains — is taxable, and either the trust or you will pay it. And when you eventually sell an inherited asset, your tax bill depends on the basis you were assigned at the grantor’s death. A few states add their own estate or inheritance tax on top.
The Principal Itself Is Not Taxed as Income
Federal law treats property you inherit as a wealth transfer rather than earned income. Section 102 of the Internal Revenue Code excludes property acquired by inheritance from gross income, so a cash distribution of principal from a trust does not get reported on your Form 1040 as income.1Office of the Law Revision Counsel. 26 USC 102 – Gifts and Inheritances That holds true whether the trust was revocable or irrevocable.
The federal estate tax is a separate transfer tax, and it is paid by the estate before anything reaches you. For deaths in 2026, the basic exclusion amount is $15 million per person, raised from $13.99 million in 2025 by the One, Big, Beautiful Bill.2Internal Revenue Service. Whats New – Estate and Gift Tax Married couples can effectively shelter up to $30 million through portability. Estates above the threshold face a top rate of 40% on the excess, but fewer than 1% of estates reach that level. As a beneficiary, you do not write a check for federal estate tax.
One exception to the “principal is not income” rule matters a lot: inherited traditional IRA or 401(k) money. Those funds were never taxed on the way in, so distributions from them are taxable income when they reach you, even if the retirement account was held inside a trust. More on that below.
Income the Trust Earns After You Inherit
Trust principal is tax-free. The earnings those assets generate are not. Whether the trust pays the tax or you do depends on how the trust is set up and whether it distributes the income.
Simple Trusts vs. Complex Trusts
A simple trust is required to distribute all of its income every year. That income flows through to the beneficiaries, who report their share on their personal returns. The trust itself pays no income tax because it takes a deduction for the amount distributed. You owe tax on your allocated share even if the money has not physically arrived yet, because the trust was required to distribute it.
A complex trust can accumulate income, distribute principal, or make charitable gifts. If it keeps the income, the trust pays tax on it. If it distributes income, you pay tax on your share.
Why Trustees Push Income Out to Beneficiaries
Trust income tax brackets are harshly compressed. For 2026, trusts and estates hit each bracket at:
- 10% up to $3,300
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% over $16,000
A trust reaches the top 37% rate at just $16,000 of taxable income. An individual filer would not get there until well over $600,000. That gap is why trustees often distribute income rather than letting the trust absorb the tax hit.
How Much of a Distribution Is Actually Taxable to You
The IRS uses distributable net income (DNI) to keep trust income from being taxed twice. DNI is the trust’s taxable income for the year, calculated with specific adjustments laid out in Section 643, and it caps how much of a distribution counts as taxable income to you.3Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D If the trust distributes more than its DNI, the excess is a tax-free return of principal.
Capital gains are usually excluded from DNI and taxed at the trust level, unless the trust document allocates them to income or the trustee specifically distributes them. So a distribution that includes proceeds from the trust selling an asset may have already been taxed inside the trust.
Schedule K-1
For each year you receive taxable distributions, the trust sends you a Schedule K-1 (Form 1041).4Internal Revenue Service. Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR It breaks the income into categories — interest, dividends, capital gains — that you then report on your personal return. The character of the income carries through: tax-exempt municipal bond interest earned inside the trust stays tax-exempt when it reaches you.
The trust must deliver your K-1 by the date it files its own return, April 15 for calendar-year trusts, unless the trust requests an extension. A late or incorrect K-1 exposes the trust to a $340 penalty per form.5Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 If yours is late and your own filing deadline is approaching, you may need to estimate and amend later.
The Basis You Inherit Decides Your Capital Gains Bill
The tax picture does not end when the trust hands you the assets. When you sell inherited property, the IRS measures your gain or loss against your “basis.” Which basis rule applies to you depends on whether the assets were included in the grantor’s taxable estate.
Stepped-Up Basis
If the trust assets were included in the grantor’s gross estate, your basis resets to the fair market value on the date of death.6Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent All the appreciation that happened during the grantor’s lifetime is wiped out for tax purposes. If the grantor bought stock for $10,000 and it was worth $100,000 on the date of death, your basis is $100,000. Selling right away produces no capital gain.
This step-up applies to assets held in revocable trusts, because the grantor’s lifetime control pulls those assets into the gross estate. It can also apply to some irrevocable trust assets if the grantor retained interests or powers that caused estate inclusion.
Carryover Basis
If an irrevocable trust successfully kept the assets out of the grantor’s taxable estate, you generally inherit the grantor’s original cost basis instead. Using the same example, your basis would stay at $10,000, and selling at $100,000 would produce a $90,000 taxable gain. On a single appreciated asset, the gap between step-up and carryover can be tens of thousands of dollars in tax. Which rule applies turns on the trust’s specific terms and how the estate tax return was handled, not just the label “irrevocable.”
Form 8971 and the Consistent-Basis Rule
If the estate was required to file Form 8971, you should receive a Schedule A showing each asset’s reported value. Federal law requires you to use a basis consistent with that reported value. Claiming a higher basis on your return exposes you to a 20% accuracy-related penalty on any resulting underpayment.7Internal Revenue Service. Instructions for Form 8971 and Schedule A
Inherited Retirement Accounts Held in Trust
Traditional IRAs and 401(k)s held inside a trust follow different rules. Distributions are taxable income to the recipient, because the account was funded with pre-tax dollars.
Under the SECURE Act, most non-spouse beneficiaries have to empty an inherited retirement account within 10 years of the original owner’s death, and the 10-year rule applies when a trust is the designated beneficiary too. How those distributions are taxed depends on the trust’s design. A conduit trust passes retirement distributions straight through to you, where they get taxed at your individual rate. An accumulation trust can hold the funds inside the trust, where they face the compressed brackets that hit 37% at $16,000.
Certain eligible designated beneficiaries can stretch distributions over their life expectancy instead of following the 10-year rule. That group includes surviving spouses, minor children of the account owner (until they reach the age of majority), disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the deceased owner. A conduit trust set up for one of these individuals may preserve the stretch option.
State Estate and Inheritance Taxes
Federal rules are only one layer. About a dozen states and the District of Columbia impose their own estate tax, often with exemption thresholds well below $5 million, and only one state currently matches the $15 million federal exemption. These taxes come out of the estate before distribution, so they reduce what you receive rather than creating a separate bill in your name.
Five states currently impose an inheritance tax, which is paid directly by the beneficiary based on what they receive. Iowa eliminated its inheritance tax in 2025. The rate depends on your relationship to the deceased person:
- Spouses are universally exempt.
- Close family such as children and parents are either exempt or taxed at 0% to 4.5%, depending on the state.
- Siblings typically face rates between 1% and 12%.
- Distant relatives and unrelated heirs face the steepest rates, roughly 11% to 15%, with exemptions sometimes as low as $500.
If the decedent lived in an inheritance tax state, or the trust holds real property located there, you may owe the tax regardless of where you live. Trustees often withhold the estimated amount before releasing your distribution. One state imposes both an estate tax and an inheritance tax, though credits generally prevent full double taxation on the same assets.
Foreign Trusts Carry Much Harsher Rules
Inheriting from a foreign trust triggers reporting obligations that domestic trust beneficiaries never face. When a foreign non-grantor trust distributes accumulated income to a U.S. beneficiary, the IRS applies throwback rules under Sections 665 through 668.8Office of the Law Revision Counsel. 26 USC 665 – Definitions Applicable to Subpart D These rules were repealed for most domestic trusts in 1997 but remain fully in force for foreign ones. They tax the distribution as if you received the income in the year the trust earned it, with an interest charge that compounds daily at the IRS underpayment rate for post-1995 accumulation periods.9Internal Revenue Service. Taxation of Beneficiary of a Foreign Non-Grantor Trust
You must report foreign trust distributions on Form 3520. The penalty for failing to file or filing with incomplete information is the greater of $10,000 or 35% of the gross distribution. On a $1 million distribution, that is $350,000. If you still have not filed 90 days after an IRS notice, continuation penalties of $10,000 every 30 days begin accruing, up to the total reportable amount.10Internal Revenue Service. Failure to File the Form 3520/3520-A Penalties The IRS does not accept the argument that a foreign jurisdiction would penalize you for disclosing the required information.
If You Receive Means-Tested Benefits
A trust distribution can wipe out eligibility for Medicaid, Supplemental Security Income, and other means-tested programs. Most of these programs count trust distributions as either income or a countable resource, and the asset limits are low. For SSI, the individual limit is typically around $2,000.
An inheritance from a properly structured special needs or supplemental needs trust may be shielded, because the beneficiary never has direct access to the funds. A lump sum from a standard trust that lands in your checking account is generally countable the moment it arrives, and spending it down afterward does not restore eligibility retroactively. If you receive or are applying for means-tested benefits, talk to an attorney before you accept the distribution.
