(a) In general. Section 4951 contains provisions that correspond to provisions of section 4941 (relating to taxes on foundation self-dealing) and section 4946 (relating to definitions and special rules). Regulations and rulings under these corresponding provisions apply to section 4951 where appropriate.

(b) Transfer of property to trust. A transfer of personal property without consideration to a trust for which a deduction is allowable under section 192 does not constitute a sale or exchange for purposes of section 4951 unless the property is subject to a mortgage or similar lien within section 4951(d)(2)(A). The transfer to a trust of a note or other evidence of indebtedness constitutes an extension of credit to the obligor for purposes of section 4951(d)(1)(B).

(c) Deposits. A time or demand deposit made with a bank or credit union that is a trustee or other disqualified person with respect to a trust constitutes a lending of money for purposes of section 4951(d)(1)(B) even though the deposit is of a kind generally authorized for investments by the trust.

(d) Trustee. The term “trustee” as used in section 4951(e)(5)(B) includes any person having powers or responsibilities with respect to a trust similar to those of trustees.

(e) Misallocation of insurance premium. Under section 501(c)(21)(A)(ii) and §1.501(c)(21)-1(d), a trust may pay a portion of a premium for insurance which covers both black lung liabilities and other liabilities, so long as the requirements of section 501(c)(21)(A)(i) concerning allocation of the total premium are met. However, if an insurance company misallocates the total premium in a manner which benefits a disqualified person, the amount of misallocation constitutes a use of trust assets for the benefit of the disqualified person within section 4951(d)(1)(D). For these purposes, it is irrelevant whether the combination of insurance is sold under one policy or more than one policy.

(f) Effective date. Section 4951 applies with respect to acts that occur after December 31, 1977, in and for trust taxable years beginning after December 31, 1977.
