Section 642(g)
Election
Administration expenses can be deducted on the estate tax return or the estate’s income tax return, but not both. With a $15 million exemption, the choice now turns on portability, state estate tax, and whether the estate has income to absorb the deduction.

The rule
Administration expenses and casualty losses allowable under IRC 2053 or 2054 cannot be deducted on both the estate tax return and an income tax return. Under IRC 642(g), they can be taken on Form 1041 only if the estate files a statement that they have not been allowed under 2053 or 2054 and waives the right to have them allowed at any time. The same rule covers selling expenses used as an offset against the sales price in computing gain or loss.
The rule does not apply to deductions in respect of a decedent under IRC 691(b): expenses the decedent incurred but had not paid at death that would have been deductible on the decedent’s own income tax return, such as business and investment expenses, interest, and taxes. When the estate pays one, it is deductible twice: as a claim against the estate on Form 706 (IRC 2053(a)(3)) and again on the Form 1041, or on the return of whoever pays it. For example, property tax that accrued before death and is paid by the estate reduces the taxable estate and is also deducted on the estate’s 1041. The double benefit is limited to items that qualify under 691(b); a personal debt such as a credit card balance is deductible only as a claim on the 706.
Which return usually gets the deduction
| Situation | Usually favors |
|---|---|
| The estate owes federal estate tax | Form 706, where the deduction saves up to 40% |
| No estate tax, and the estate has taxable income | Form 1041, where it saves income tax at trust rates (37% above $16,000 in 2026) |
| Form 706 filed only to elect portability | Compare: on the 706 it can increase the DSUE; on the 1041 it saves income tax now |
| The estate owes state estate tax | Check the state return, which often follows the federal 706 deductions |
| Final year, with deductions exceeding income | Form 1041, where the excess can pass to beneficiaries |
| Expenses the decedent owed at death that would have been income tax deductions (accrued property tax, interest, business or investment expenses) | Both returns: these deductions in respect of a decedent are exempt from the rule. Personal debts, like a credit card balance, count only on the 706 |
Making the waiver
- Content: a statement that the items have not been allowed as deductions under 2053 or 2054, and a waiver of all rights to have them allowed at any time.
- Timing: it can be filed with the Form 1041 for the year the deduction is taken, or later, at any time before the limitations period for that income tax year expires.
- Claimed on the 706 first: claiming an expense on the estate tax return does not bar the income tax deduction, as long as the estate tax deduction has not been finally allowed and the statement is filed.
- Irrevocable: once the statement is filed for an item, that item can never be deducted for estate tax purposes.
- Partial elections: expenses can be divided, with some items, or portions of items, taken on each return (Treas. Reg. 1.642(g)-2).
Running the numbers
With the federal exclusion at $15,000,000 for 2026, most estates owe no federal estate tax, so the 1041 is usually the better home for administration expenses. The analysis still turns on specifics:
- Taxable estates: the 706 deduction saves estate tax at up to 40%, which generally beats the income tax benefit. Marital and charitable deduction interactions can change the effective rate.
- Portability returns: expenses deducted on the 706 reduce the taxable estate and can increase the DSUE passed to the surviving spouse. Where the survivor’s estate may be taxable, that future benefit has to be weighed against income tax saved now.
- State estate tax: many state estate tax returns start from the federal 706, so moving an expense to the 1041 can increase state estate tax. In states where no federal return is otherwise required, the state rules on deducting administration expenses control.
- Income to absorb the deduction: a 1041 deduction only helps if there is income to offset. Deductions exceeding income in the final year pass through to beneficiaries, where they are not miscellaneous itemized deductions.
- Tax-exempt income: a portion of fees allocable to tax-exempt income is not deductible on the 1041, which does not limit the 706 deduction.
- Commissions on the 706: executor commissions are deductible for estate tax only if they will actually be paid.
What we handle
- Modeling each expense on the 706, the 1041, and the state estate tax return
- Splitting expenses between returns where that produces the best result
- Preparing and filing 642(g) statements, including late statements while the year is open
- Tracking which items were claimed where, so nothing is deducted twice or lost
- Deductions in respect of a decedent on both returns
- Final-year excess deductions passed to beneficiaries
