What Is Considered Income for an Estate: Types, Taxes, and Deductions

Income for an estate is what the decedent’s assets earn after the date of death — interest, dividends, rent, business profits, capital gains on sales, and royalties — plus certain payments the person had earned but not yet received before dying. Any estate with $600 or more in gross income during a tax year files its own return on Form 1041, and the brackets are compressed enough that undistributed income hits the top 37% rate at just $16,000 for 2026.

One quick boundary: this is the estate income tax, not the federal estate tax. The estate tax is a one-time levy on the total value of what the decedent owned, and most estates never owe it because the exemption sits above $13 million. What follows is about the income the estate earns while the executor is administering it.

Principal Versus Income

Estate administration turns on the line between principal and income. Principal (sometimes called the corpus) is whatever the decedent owned at death: the house, the brokerage account, the bank balance. Income is what those assets produce afterward. A rental property is principal; the rent that arrives after death is income. A stock portfolio is principal; the dividends it pays after the owner dies are income.

This distinction decides what goes on the estate’s income tax return, and it often decides who gets paid what. Many wills direct income to one set of beneficiaries and principal to another, so misclassifying a receipt can send money to the wrong person and put the tax on the wrong party.

What Counts as Estate Income

Investment Income

Interest earned on bank accounts, CDs, and bonds after the date of death is estate income.¹ So are dividends from stocks and mutual funds, and royalties from any intellectual property the decedent held. The underlying assets stay principal; only what they throw off is income.

Interest on state and local government bonds generally stays tax-exempt even when the estate receives it.² The estate still reports the tax-exempt interest on Form 1041, but it doesn’t add to taxable income.

Rental and Lease Income

Rent collected after the date of death is estate income. If the decedent died partway through a rental month, only the portion of that month’s rent attributable to the days after death belongs to the estate.¹ Rent for full months after death is straightforward estate income. The same rule applies to lease payments on equipment, vehicles, or other tangible property the estate owns.

Business Income

If the decedent owned or held an interest in an operating business, the net profits earned after death are estate income, whether the business is a sole proprietorship, a partnership interest, or a closely held corporation.¹ What’s income here is the ongoing operational profit, not what the executor eventually gets if the business is sold. Sale proceeds fall under capital gains.

For pass-through entities, the business issues a Schedule K-1 reporting the estate’s share. The executor needs to give the business the estate’s taxpayer identification number so the K-1 is issued correctly. If the business runs on a fiscal year different from the estate’s, the estate reports the income in the year the business’s fiscal year ends.

Capital Gains

When the estate sells an asset for more than its tax basis, the profit is a capital gain and counts as estate income. Inherited property generally takes a stepped-up basis equal to its fair market value on the date of death.³ The lifetime appreciation is wiped out for tax purposes, so the estate only owes gains tax on the change in value between death and sale.

If the decedent bought stock for $10,000, it was worth $50,000 at death, and the estate sells it for $53,000, the capital gain is $3,000, not $43,000. The stepped-up basis is one of the most valuable features of inherited property. It has an important exception, though, covered next.

Income in Respect of a Decedent

Income in respect of a decedent (IRD) is money the decedent had earned or was entitled to receive before death but that hadn’t appeared on any tax return yet. IRD is taxed as income when actually received, and it does not get a stepped-up basis.³ This is where executors and beneficiaries most often get tripped up.

Common IRD items:

Traditional IRA and 401(k) distributions. The decedent contributed pre-tax money, so distributions to the estate or beneficiary are taxable, just as they would have been to the decedent. For many estates, retirement accounts are the single largest IRD item.⁴
Unpaid wages and bonuses. A paycheck earned before death but paid after is IRD.
Accrued interest and dividends. Interest that accumulated before death but was paid after (like a bond coupon) is IRD rather than ordinary estate income.
Deferred compensation and commissions the decedent had earned but not collected.

The character of the income carries over from the decedent. If it would have been ordinary income to the decedent, it’s ordinary income to whoever receives it.⁵ The practical impact is significant. A $500,000 IRA does not get a fresh basis at death the way a $500,000 stock portfolio does. Every dollar withdrawn is taxable.

When the Estate Has to File

An estate must file Form 1041 for any tax year in which its gross income reaches $600.⁶ The estate needs its own Employer Identification Number; the decedent’s Social Security number isn’t used for estate income tax.⁷

Unlike trusts, an estate can elect a fiscal year rather than a calendar year. If the decedent died in March, the executor can choose a fiscal year ending any month up to and including February of the following year. A well-chosen fiscal year defers the first tax payment and gives the executor more time to plan distributions. A calendar-year estate files Form 1041 by April 15 of the following year.⁶

How Estate Income Is Taxed

Income the estate keeps rather than distributing gets taxed at the estate level, and the brackets are compressed. For 2026:⁸

10% on taxable income up to $3,300
24% from $3,301 to $11,700
35% from $11,701 to $16,000
37% on income over $16,000

An individual doesn’t hit 37% until taxable income exceeds roughly $626,000. An estate hits it at $16,000. That compression is the single biggest reason estate income planning matters. Leaving income inside the estate when a beneficiary in a lower bracket could receive it is one of the most expensive mistakes an executor can make.

Reducing the Estate’s Income Tax

Distribute Income to Beneficiaries

The most powerful tool is the income distribution deduction. When the estate distributes income to beneficiaries, it deducts those distributions on its own return, and the beneficiaries report the income on their personal returns.⁶ The estate issues each beneficiary a Schedule K-1 showing their share. Because most beneficiaries have far more room in the lower brackets than the estate does, this shift produces real savings.

The deduction is capped at the estate’s distributable net income, so the estate can’t deduct more than it actually earned. Timing helps too: the executor can make distributions in the first 65 days of a new tax year and elect to treat them as if they were made on the last day of the prior year.⁹ That gives the executor time to see the full picture before deciding how much to send out.

Deduct Administration Expenses

The estate can deduct the costs of administering itself against its income. Deductible items include executor commissions, attorney fees, accountant fees, court costs, appraisal fees, and expenses for selling property when the sale is necessary to pay debts or make distributions.¹⁰ The same expense can’t be deducted on both Form 706 and Form 1041, so the executor picks whichever return produces the bigger benefit.

Choose a Fiscal Year Strategically

If the decedent died in June 2026 and the executor picks a fiscal year ending January 31, the estate’s first year runs from June through January 2027, and the first Form 1041 isn’t due until May 2027. Beyond the deferral, a well-chosen fiscal year can line up more income with the years when the estate plans to make larger distributions, so the distribution deduction absorbs more of the tax.
