§ 1.167(h)-1 Life tenants and beneficiaries of trusts and estates.
Federal Code of Regulations
(a) Life tenants. In the case of property held by one person for life with remainder to another person, the deduction for depreciation shall be computed as if the life tenant were the absolute owner of the property so that he will be entitled to the deduction during his life, and thereafter the deduction, if any, shall be allowed to the remainderman.
(b) Trusts. If property is held in trust, the allowable deduction is to be apportioned between the income beneficiaries and the trustee on the basis of the trust income allocable to each, unless the governing instrument (or local law) requires or permits the trustee to maintain a reserve for depreciation in any amount. In the latter case, the deduction is first allocated to the trustee to the extent that income is set aside for a depreciation reserve, and any part of the deduction in excess of the income set aside for the reserve shall be apportioned between the income beneficiaries and the trustee on the basis of the trust income (in excess of the income set aside for the reserve) allocable to each. For example:
(1) If under the trust instrument or local law the income of a trust computed without regard to depreciation is to be distributed to a named beneficiary, the beneficiary is entitled to the deduction to the exclusion of the trustee.
(2) If under the trust instrument or local law the income of a trust is to be distributed to a named beneficiary, but the trustee is directed to maintain a reserve for depreciation in any amount, the deduction is allowed to the trustee (except to the extent that income set aside for the reserve is less than the allowable deduction). The same result would follow if the trustee sets aside income for a depreciation reserve pursuant to discretionary authority to do so in the governing instrument.
No effect shall be given to any allocation of the depreciation deduction which gives any beneficiary or the trustee a share of such deduction greater than his pro rata share of the trust income, irrespective of any provisions in the trust instrument except as otherwise provided in this paragraph when the trust instrument or local law requires or permits the trustee to maintain a reserve for depreciation.
(c) Estates. In the case of an estate the allowable deduction shall be apportioned between the estate and the heirs legatees, and devisees on the basis of income of the estate which is allocable to each.
