26 CFR § 1.6032-1 - Returns of banks with respect to common trust funds.
(a) Every bank (as defined in section 581) maintaining a common trust fund shall make a return of income of the common trust fund, regardless of the amount of its taxable income. Member banks of an affiliated group that serve as co-trustees with respect to a common trust fund must act jointly in making a return for the fund. If a bank maintains more than one common trust fund, a separate return shall be made for each. No particular form is prescribed for making the return under this section, but Form 1065 may be used if it is designated by the bank as the return of a common trust fund. The return shall be made for the taxable year of the common trust fund and shall be filed on or before the date prescribed by section 6072(b) with the service center prescribed in the relevant Internal Revenue Service revenue procedure, publication, form, or instructions to the form (see § 601.601(d)(2) of this chapter). Such return shall state specifically with respect to the fund the items of gross income and the deductions allowed by subtitle A of the Internal Revenue Code, shall include each participant's name and address, the participant's proportionate share of taxable income or net loss (exclusive of gains and losses from sales or exchanges of capital assets), the participant's proportionate share of gains and losses from sales or exchanges of capital assets, and the participant's share of items which enter into the determination of the tax imposed by section 56. See §§ 1.584-2 and 1.58-5. If the common trust fund is maintained by two or more banks that are members of the same affiliated group, the return must also identify the member bank in the group that has contributed each participant's property or money to the fund. A copy of the plan of the common trust fund must be filed with the return. If, however, a copy of such plan has once been filed with a return, it need not again be filed if the return contains a statement showing when and where it was filed. If the plan is amended in any way after such copy has been filed, a copy of the amendment must be filed with the return for the taxable year in which the amendment was made. For the signing of a return of a bank with respect to common trust funds, see § 1.6062-1, relating to the manner prescribed for the signing of a return of a corporation.
(b) This section applies to returns filed on or after January 30, 2020. Section 1.6032-1T (as contained in 26 CFR part 1, revised April 2019) applies to taxable years beginning before January 30, 2020.
