Section 642: Special Tax Rules for Estates and Trusts

The tax code establishes specific rules for the income taxation of estates and trusts, treating them as distinct taxable entities. These regulations, outlined in Internal Revenue Code Section 642, create a framework of deductions and credits that differ from those available to individual taxpayers. The purpose of these rules is to ensure that income earned by the assets held within a trust or estate is taxed appropriately, either to the entity itself or to the beneficiaries who receive distributions. This system governs how an entity’s taxable income is calculated before the tax liability is determined.

Core Deductions for Fiduciary Income Tax

The personal exemption for fiduciaries functions differently than the one for individuals. An estate is permitted a $600 deduction. A simple trust, which is required to distribute all its income currently, can claim a $300 deduction, while all other trusts, known as complex trusts, are allowed a $100 deduction. The suspension of personal exemptions for individuals under the Tax Cuts and Jobs Act of 2017 did not extend to estates and trusts, so they continue to benefit from these amounts.

A deduction is also available for contributions made to charitable organizations. An estate or trust can take an unlimited deduction for any amount of its gross income that is paid to a qualified charity, which contrasts with the income-based limits for individuals. For the deduction to be valid, the payment must come from the entity’s gross income and be explicitly authorized by the will or trust document.

A trust must generally pay the funds to the charity during the tax year to secure the deduction. An estate has more flexibility and can claim a deduction for funds that are permanently set aside for a future charitable distribution. The deduction is limited to amounts paid from gross income. If a contribution is made from the principal, or corpus, it does not qualify for the income tax deduction unless the governing document specifies otherwise. If the document is silent on the source, the payment is deemed to consist of a proportionate share of all income types the entity earned.

Allocating Administrative Expenses

Executors have a choice regarding the treatment of certain administrative expenses, such as executor commissions, attorney fees, and appraisal costs. These costs can be deducted on either the federal estate tax return (Form 706) to reduce the taxable estate, or on the fiduciary income tax return (Form 1041) to lower the estate’s taxable income. If an estate is subject to federal estate tax, a deduction on Form 706 may be more valuable. If the estate is not subject to estate tax but has significant taxable income, deducting the expenses on Form 1041 is often more advantageous. The decision requires comparing the marginal estate tax rate with the estate’s marginal income tax rate.

The same administrative expense cannot be deducted on both returns. To claim these costs on the fiduciary income tax return, the executor must file a waiver statement with the Form 1041. This statement affirms that the amounts have not been claimed for federal estate tax purposes and that the right to do so is irrevocably waived. Once the waiver is filed, the decision cannot be reversed.

Deductions Passed to Beneficiaries at Termination

Certain unused tax attributes can be passed from an estate or trust to its beneficiaries in the entity’s final year. This transfer of tax benefits occurs only upon the complete termination of the estate or trust, allowing beneficiaries to use deductions the entity could not.

An unused net operating loss (NOL) carryover from a trade or business can be distributed to the beneficiaries. These beneficiaries can then use this NOL on their own tax returns as a deduction against their income. Any unused capital loss carryovers of the estate or trust are also passed on to the beneficiaries, who can use them to offset their own capital gains and, to a limited extent, ordinary income.

If the deductions of the estate or trust are greater than its gross income in its final tax year, the difference is passed to the beneficiaries as “excess deductions on termination.” These excess deductions, which often include final administrative fees, retain their character when passed through. This allows beneficiaries to deduct many of these costs directly from their adjusted gross income.

Rules for Other Deductions and Credits

Deductions for depreciation and depletion are allocated between the fiduciary and the beneficiaries based on the amount of trust or estate income distributed to each. If a trust maintains a reserve for depreciation, the deduction is first allocated to the trust up to the amount of that reserve.

An estate or trust can claim a net operating loss (NOL) deduction if its deductions from operating a trade or business exceed its gross income. This NOL can be carried to other tax years to offset the entity’s income. This is distinct from the rule that passes an unused NOL to beneficiaries at termination.

The Tax Cuts and Jobs Act of 2017 suspended many miscellaneous itemized deductions for individuals, but an exception exists for fiduciaries. They can still deduct administration costs that would not have been incurred if the property were not held in an estate or trust. This allows deductions for unique fiduciary expenses, such as trust accounting and certain legal fees.

Tax credits, such as the foreign tax credit, are allocated between the estate or trust and its beneficiaries. The allocation is based on the proportion of income associated with the credit that is distributable to the beneficiaries versus the amount retained by the fiduciary.
