Income received after death is generally taxed on one of three returns: the deceased person’s final Form 1040 for anything earned up to the date of death, the estate’s Form 1041 for income the estate’s assets produce afterward, and the individual returns of beneficiaries who directly receive money the decedent had a right to but never collected. Which return a particular payment lands on depends on when it was earned, when it was paid, and who actually received it.
Which Return the Income Belongs On
The date of death is the dividing line. Everything the person earned from January 1 through that date goes on a final Form 1040, filed by the surviving spouse or the executor. Anything the person’s assets generate after the date of death belongs to the estate, which becomes a separate taxpayer the moment the person dies. If the estate takes in $600 or more in gross income during its tax year, the executor must file Form 1041.
There is a third bucket, and it’s the one that catches people off guard. When the deceased had already earned income or had a fixed right to receive it, but the payment didn’t arrive until after death, that money is reported by whoever actually receives it. Sometimes that’s the estate. Sometimes it’s a beneficiary who inherited the right to collect it. Either way, it doesn’t go on the final 1040.
Filing Form 1041 requires the estate to have its own Employer Identification Number. The executor can apply online through the IRS website and receive one immediately, or send Form SS-4 by fax or mail. When the estate distributes income to beneficiaries, it generally gets a deduction for those distributions, and each beneficiary reports their share on their own return using a Schedule K-1 from the estate.
Income in Respect of a Decedent
The IRS label for that third bucket is “income in respect of a decedent,” and it covers unpaid salary, accrued interest, installment sale payments, and retirement account distributions. It’s the income the person would have received had they lived.
Two things about this category matter to whoever ends up with the money. First, the recipient reports it as ordinary income when the payment arrives. If you inherit the right to receive an installment payment, you report that income in the year it’s paid to you, at your own ordinary income rates.
Second, the same money can be taxed twice: once as part of the decedent’s taxable estate for federal estate tax purposes, and again as ordinary income to the recipient. To offset that, whoever reports the income can claim an income tax deduction for the share of federal estate tax attributable to it.
How Common Types of Post-Death Income Are Taxed
Final Wages and Accrued Pay
A last paycheck, unused vacation, or a bonus earned before death but paid after is income in respect of a decedent. No federal income tax is withheld when the payment goes to the estate or a beneficiary.
Social Security and Medicare withholding depends on when the wages are actually paid. If the payment comes during the same calendar year as the death, the employer still withholds Social Security and Medicare taxes and reports the wages on the deceased person’s W-2, though not in the box used for income tax. If the wages aren’t paid until a later calendar year, no federal taxes of any kind are withheld, and the employer reports the payment on Form 1099-MISC to whoever received it.
Inherited Retirement Accounts
Balances in 401(k)s, IRAs, and pensions become payable to whoever is named on the beneficiary form. Distributions from these accounts are income in respect of a decedent and taxed to the recipient at ordinary income rates.
If the account owner died in a year when they were required to take a minimum distribution but hadn’t taken the full amount, the beneficiary has to withdraw the remainder. Missing that step triggers an excise tax of 25% on the shortfall, which drops to 10% if corrected within two years.
For account owners who died after 2019, most non-spouse individual beneficiaries have to empty the inherited account by the end of the tenth year after the year of death. Whether annual withdrawals are required during those ten years depends on whether the original owner had reached their required beginning date. Certain “eligible designated beneficiaries”—surviving spouses, minor children of the account owner, disabled or chronically ill individuals, and beneficiaries not more than ten years younger than the deceased—can stretch distributions over their own life expectancy instead. A surviving spouse who is the sole beneficiary can elect to treat the inherited IRA as their own.
Investment Income and Rental Income
Interest, dividends, and capital gains that settle after the date of death, along with rent from properties the deceased owned, belong to the estate for tax purposes and go on Form 1041 until the property is transferred or sold. Once the estate distributes that income to beneficiaries, the estate deducts it and each beneficiary picks it up on their own return.
Inherited Property and the Step-Up in Basis
One rule works in the beneficiary’s favor. When you inherit property, the tax basis resets to the fair market value on the date of death. A stock your parent bought for $10,000 that was worth $100,000 when they died has a $100,000 basis in your hands. Sell it a month later for $101,000 and you owe capital gains tax on $1,000, not $91,000.
The step-up applies to property acquired by bequest, inheritance, or from the decedent’s estate. It does not apply to income in respect of a decedent, which is why retirement account distributions and unpaid wages stay taxable as ordinary income no matter when the decedent originally earned them.
Filing Deadlines
The final Form 1040 follows the normal individual calendar. If the person died at any point during 2025, the return is due April 15, 2026. The standard six-month extension is available.
The estate’s Form 1041 can run on a calendar year or a fiscal year. A calendar-year estate files by April 15 of the following year. A fiscal-year estate files by the 15th day of the fourth month after its fiscal year ends. Form 7004 gets the executor an automatic five-and-a-half-month extension.
Penalties for Missing a Deadline
Late filing on either return brings the same penalties as any other tax return. The failure-to-file penalty is 5% of the unpaid tax for each month the return is late, capped at 25%. A separate failure-to-pay penalty runs at 0.5% per month. When both apply in the same month, the filing penalty is reduced by the payment penalty so they don’t fully stack.
The executor is the one on the hook for getting these filed, which is worth knowing early. Grieving family members frequently don’t realize a return is due at all, much less that someone has personal responsibility for it.
Managing the Money in the Meantime
The first practical step is opening a dedicated estate bank account. Commingling estate funds with the executor’s personal accounts creates legal exposure and erodes trust with beneficiaries. Every dollar in or out needs a record of the source, amount, date, and purpose. That documentation feeds the 1041, satisfies any accounting a court or beneficiary can demand, and protects the executor if the handling of funds is later questioned.
Beneficiary designations on retirement accounts, life insurance, payable-on-death bank accounts, and transfer-on-death investment accounts override whatever the will says. If a 401(k) form still lists an ex-spouse, the ex-spouse receives that account regardless of what the will directs. That matters for the tax analysis because it determines who receives the income and, therefore, who reports it.
