The money or property you receive as principal from a trust inheritance is generally not subject to federal income tax, but the taxes on a trust inheritance don’t stop there. Any income the trust earns and passes to you is taxable, your cost basis when you later sell inherited assets can swing your tax bill by tens of thousands of dollars, and a handful of states tack on their own estate or inheritance tax before the money reaches you. Here is what actually applies, and when.
The Principal Itself Isn’t Taxed as Income
Federal law treats an inheritance as a wealth transfer, not earned income. IRC Section 102 specifically excludes property acquired by inheritance from gross income, and that exclusion applies whether the assets come through a revocable trust, an irrevocable trust, or a will.1Office of the Law Revision Counsel. 26 USC 102 – Gifts and Inheritances You don’t report the principal on your Form 1040.
The federal estate tax is a separate transfer tax, and it’s paid by the estate before assets reach you. For deaths in 2026, the basic exclusion amount is $15 million per person, raised from $13.99 million in 2025.2Internal Revenue Service. Whats New – Estate and Gift Tax Married couples can effectively double that through portability. Estates above the threshold face a top rate of 40% on the excess. Because the exemption is so high, fewer than 1% of estates pay federal estate tax at all, and as the beneficiary you’re not the one writing that check.
The Generation-Skipping Transfer tax is another estate-level tax. It applies when assets pass to someone two or more generations below the grantor, such as a grandchild. The GST exemption matches the basic exclusion at $15 million in 2026, and the rate is 40%.3Office of the Law Revision Counsel. 26 USC 2631 – GST Exemption Like the estate tax, it’s paid before distribution.
Trust Income That Flows to You Is Taxable
Once the trust holds the assets, anything they earn — interest, dividends, rent, capital gains — is taxable. Whether the trust pays that tax or you do depends on whether the income is distributed.
The IRS uses distributable net income to keep the same dollar from being taxed twice. DNI is the trust’s taxable income for the year with specific adjustments under IRC Section 643, and it caps how much of any distribution to you counts as taxable income.4Office 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 treated as 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 distributes them. So a distribution funded by an asset sale may already have been taxed inside the trust.
Simple Trusts vs. Complex Trusts
A simple trust must distribute all income each year and cannot distribute principal or make charitable gifts. The income flows through to you, you report your share, and the trust pays no income tax because it deducts the distribution. You owe tax on your allocated share of DNI even if the cash hasn’t arrived, because the trust was required to distribute it.
A complex trust can accumulate income, distribute principal, or make charitable contributions. If it retains income, the trust pays the tax. If it distributes income, you pay the tax up to the DNI limit.
Schedule K-1 Reports Your Share
Each year you receive taxable distributions, the trust sends you Schedule K-1 (Form 1041) breaking down the type and amount of income you need to report on your personal return.5Internal Revenue Service. Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR Character carries through: municipal bond interest that was tax-exempt in the trust stays tax-exempt on your return; qualified dividends stay qualified dividends.
The trust must provide the K-1 by the date it files Form 1041, which is April 15 for calendar-year trusts unless the trust files an extension. A late or incorrect K-1 exposes the trust to a $340 penalty per form.6Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 If yours is delayed, you may need to estimate the income, file, and amend later.
Why the Trust’s Compressed Brackets Matter to You
Trust and estate income tax brackets are steep. In 2026:
- 10% on income up to $3,300
- 24% on income from $3,301 to $11,700
- 35% on income from $11,701 to $16,000
- 37% on income over $16,000
A trust hits the top 37% bracket at just $16,000 of taxable income. An individual doesn’t reach that rate until income well above $600,000. That gap gives trustees a strong reason to push income out to beneficiaries in lower brackets rather than let it sit and get taxed at trust rates.
There’s also a timing tool worth knowing about. Under IRC Section 663(b), a trustee can elect to treat distributions made in the first 65 days of a new tax year as if they occurred on the last day of the prior year.7eCFR. 26 CFR 1.663(b)-1 – Distributions in First 65 Days of Taxable Year If the trust had an unexpectedly high income year, this election can shift that income to you at your lower personal rate. It has to be made on the trust’s return for the year the income was earned, and the trustee makes a fresh election each year.
Your Basis When You Sell Inherited Assets
The biggest tax question after you inherit isn’t usually the year you receive the assets — it’s the year you sell them. Your capital gain or loss is measured from your basis, and the basis rules turn 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 under IRC Section 1014.8Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent All the appreciation that accumulated during the grantor’s lifetime disappears for tax purposes. If the grantor bought stock for $10,000 and it was worth $100,000 at death, your basis is $100,000. Selling right away produces zero gain.
This step-up applies to assets in revocable living trusts, which are always included in the grantor’s gross estate because the grantor kept the power to change them. It also applies to irrevocable trust assets that were pulled back into the gross estate because the grantor retained certain interests or powers. The label “irrevocable” doesn’t decide the question; the trust’s specific terms and how the estate tax return was filed do.
Carryover Basis
If the irrevocable trust successfully kept the assets out of the grantor’s taxable estate, those assets don’t get a step-up. You take the grantor’s original cost basis instead. Using the same numbers, your basis stays at $10,000, and selling for $100,000 produces a $90,000 taxable capital gain.
To figure out which basis applies, review the trust document and the estate tax return. If the estate was required to file Form 8971, you’ll receive a Schedule A listing each asset and the value the estate reported. You have 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.9Internal Revenue Service. Instructions for Form 8971 and Schedule A
Inherited Retirement Accounts Held in Trust
If the trust inherited a traditional IRA or 401(k), distributions from that account are taxable income when they reach you. Retirement funds were never taxed on the way in, so they don’t get the income-tax-free treatment Section 102 gives to other inherited assets.
The SECURE Act generally requires most non-spouse beneficiaries 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. How those distributions get taxed depends on the trust structure. A conduit trust passes the retirement distribution straight through to you and it’s taxed at your individual rate. An accumulation trust can hold the funds inside the trust, where they face those compressed brackets that hit 37% at $16,000.
Certain eligible designated beneficiaries — including surviving spouses, minor children of the account owner, disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the deceased — can stretch distributions over their life expectancy instead of following the 10-year rule. If a trust is structured as a conduit trust for one of these individuals, that stretch option may still be available.
State Estate and Inheritance Taxes
Federal treatment isn’t the whole picture. About a dozen states and the District of Columbia impose their own estate tax, with exemption thresholds ranging from roughly $1 million up to the federal level. Most sit well below $5 million. State estate tax is paid by the estate before distribution, so it reduces what you receive rather than creating a separate bill.
Five states impose an inheritance tax, which is different: you pay it, based on what you receive. Iowa eliminated its inheritance tax in 2025. Rates depend on your relationship to the deceased. Spouses are universally exempt. Close family generally pays 0% to 4.5%. Siblings typically fall in a 1% to 12% range. Distant relatives and unrelated heirs face the top rates, roughly 11% to 15%, sometimes with exemptions as low as $500.
One state levies both, though credits generally prevent full double taxation on the same assets. If the decedent lived in an inheritance tax state, or if 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.
Foreign Trust Distributions Carry Severe Reporting Penalties
Inheriting from a foreign trust triggers reporting the domestic rules don’t. Distributions of accumulated income from a foreign non-grantor trust to a U.S. beneficiary run through the throwback rules under IRC Sections 665 through 668, which were repealed for most domestic trusts in 1997 but remain in force for foreign trusts.10Office of the Law Revision Counsel. 26 USC 665 – Definitions Applicable to Subpart D The distribution is taxed as if you received it in the year the trust earned the income, plus a compounding interest charge at the IRS underpayment rate.11Internal Revenue Service. Taxation of Beneficiary of a Foreign Non-Grantor Trust
You must also report the distribution 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’s a $350,000 penalty. If you still haven’t filed 90 days after IRS notice, continuation penalties of $10,000 every 30 days begin, up to the total reportable amount.12Internal Revenue Service. Failure to File the Form 3520/3520-A Penalties
Watch Out for Means-Tested Benefits
If you receive Medicaid, Supplemental Security Income, or other means-tested benefits, a trust distribution can knock you off eligibility. Most programs count distributions as either income or a countable resource, and asset limits are low — typically around $2,000 for individuals on SSI.
A properly structured special needs or supplemental needs trust may be shielded because the beneficiary doesn’t have direct access to the funds. A lump sum from a standard trust that lands in your bank account is generally countable the moment it arrives. Spending it down afterward doesn’t undo the eligibility problem retroactively. If you’re on or applying for means-tested benefits, talk to an attorney before accepting the distribution.
