What Is Income in Respect of a Decedent?

Learn what income in respect of a decedent means, who reports IRD, why it gets no basis step-up, and when an estate-tax deduction may apply.

Income in respect of a decedent, commonly called IRD, is income a deceased person was entitled to but that was not properly included in taxable income before death. The estate, beneficiary, or other recipient generally reports the income when it is received. Unlike many inherited assets, IRD generally does not receive a date-of-death basis adjustment.

Key distinction IRD is not reported merely because cash arrives after death. It is income tied to the decedent's pre-death right that was not already included on the final return.

How IRD arises

Most individuals use the cash method of accounting. Their final Form 1040 generally includes income actually or constructively received before death. If the person had a right to income but did not receive it before death, the right and later payment may be IRD.

Common examples include:

  • Unpaid wages, bonuses, commissions, or accrued vacation pay
  • Traditional IRA and pretax retirement-plan distributions
  • Deferred compensation and certain annuity income
  • Interest accrued before death but paid afterward
  • Installment-sale gain not yet recognized
  • Rent earned before death but collected afterward
  • A cash-method owner's unpaid business receivables
  • Crop shares or other income under specialized rules

The recipient reports the item with the character it would have had to the decedent. Wages remain compensation; retirement distributions follow retirement rules; interest remains interest; and installment gain retains its character.

Example: final return versus IRD recipient

Assume Elena dies on June 20. Her employer owes her a $12,000 bonus for work completed before death, but pays it to her estate in August. Elena used the cash method and could not access the bonus before death.

The $12,000 is generally not placed on Elena's final Form 1040 merely because she earned it before death. It is generally IRD reported by the estate when received. If the estate later distributes the related income, Form 1041 and DNI rules may carry the character to a beneficiary.

Now assume Elena's bank credited interest to her unrestricted account on June 19. That amount may have been constructively received before death and belong on her final return instead. The payment date alone does not decide the taxpayer; the right to and availability of the income matter.

Why IRD does not receive a step-up in basis

Many capital assets included in a decedent's estate receive a basis generally tied to fair market value at death. IRD is different because the embedded income has not yet been subjected to income tax. Giving the right to that income a full fair-market-value basis would potentially eliminate the income tax that would have applied if the decedent had collected it.

For example, the pretax portion of an inherited traditional IRA remains taxable as distributed. Calling the account an inheritance does not turn its untaxed earnings and deductible contributions into tax-free basis. See also: Step-Up in Basis.

Who reports IRD?

IRD is generally reported by whoever receives the right or payment: the decedent's estate, a trust, a beneficiary, or another successor. If the right is transferred before collection, special rules can trigger income or determine the new recipient's reporting.

The information return may show the decedent's, estate's, or beneficiary's taxpayer identification number depending on timing and payer procedures. A mismatched Form 1099 should not be ignored. The fiduciary should document the correct taxpayer and seek correction or attach an explanation when appropriate.

IRD and Form 1041

When an estate receives IRD, it generally reports the item on Form 1041 in the appropriate income category. If the estate distributes income to beneficiaries, DNI and the income distribution deduction determine what is retained by the estate and what is carried out on Schedule K-1.

IRD can therefore intersect with two different systems: Section 691 determines that the income survives death, while the Form 1041 distribution rules determine whether the estate or beneficiary bears the current income tax.

The estate-tax deduction for IRD

IRD can be included in the decedent's gross estate for federal estate-tax purposes and later be subject to income tax when collected. When federal estate tax is attributable to the net value of IRD, the recipient may qualify for an income-tax deduction under Section 691(c).

This deduction is not automatic, is not the entire estate tax, and is uncommon when no federal estate tax was paid. It requires a calculation of the estate tax attributable to net IRD. Preserve Form 706, valuation workpapers, expenses tied to IRD, and allocation records.

California treatment

California generally follows the concept that the recipient reports income received after a decedent's death, but federal and California character, basis, and deductions should be reconciled. California has no current separate inheritance tax merely because someone receives inherited property, and an inheritance itself is generally excluded from income. Income produced by inherited property and IRD can still be taxable.

An estate or trust may report California items on Form 541 and beneficiaries may receive Schedule K-1 (541). California-source income can remain taxable to a nonresident recipient. Do not assume a federal Section 691(c) deduction produces an identical California result without checking current state instructions.

Common mistakes

  • Reporting every post-death check on the final Form 1040
  • Treating inherited retirement distributions as tax-free inheritance
  • Applying a fair-market-value basis step-up to IRD
  • Omitting a payment because a Form 1099 used the wrong identification number
  • Taxing the same item on both the final return and Form 1041
  • Missing the potential Section 691(c) deduction when estate tax was paid
  • Failing to preserve installment, retirement, payroll, or receivable records

Records to gather

  • Final pay statements and employment agreements
  • Retirement and annuity beneficiary statements
  • Forms 1099-R, 1099-INT, 1099-NEC, and W-2
  • Installment-sale contracts and basis schedules
  • Accounts-receivable and rental ledgers
  • Date-of-death account statements
  • Final Form 1040, Form 1041, K-1 forms, and Form 706
  • Documentation showing when income became payable or available

Frequently asked questions

Is an inherited IRA always IRD?

The taxable pretax portion is generally IRD as distributions are received. Any documented nondeductible basis follows separate allocation rules.

Does IRD go on the decedent's final return?

Generally no, if it was not actually or constructively received and not otherwise includible before death. The proper recipient reports it later.

Is IRD taxed twice?

It can be included in the federal gross estate and also subjected to income tax. A Section 691(c) deduction may reduce the income-tax effect when federal estate tax was attributable to the IRD.

Does every asset received after death create IRD?

No. Inherited cash or appreciated property is not IRD merely because ownership transfers after death. IRD is an untaxed income right attributable to the decedent.
