((c)) ** Excess inclusion** For purposes of this section—
((1)) ** In general** The term “excess inclusion” means, with respect to any residual interest in a REMIC for any calendar quarter, the excess (if any) of—

((B)) the sum of the daily accruals with respect to such interest for days during such calendar quarter while held by such holder.
((2)) ** Determination of daily accruals**
((A)) ** In general** For purposes of this subsection, the daily accrual with respect to any residual interest for any day in any calendar quarter shall be determined by allocating to each day in such quarter its ratable portion of the product of—
((i)) the adjusted issue price of such interest at the beginning of such quarter, and
((ii)) 120 percent of the long-term Federal rate (determined on the basis of compounding at the close of each calendar quarter and properly adjusted for the length of such quarter).
((B)) ** Adjusted issue price** For purposes of this paragraph, the adjusted issue price of any residual interest at the beginning of any calendar quarter is the issue price of the residual interest (adjusted for contributions)—
((i)) increased by the amount of daily accruals for prior quarters, and
((ii)) decreased (but not below zero) by any distribution made with respect to such interest before the beginning of such quarter.
((C)) ** Federal long-term rate** For purposes of this paragraph, the term “Federal long-term rate” means the Federal long-term rate which would have applied to the residual interest under section 1274(d) (determined without regard to paragraph (2) thereof) if it were a debt instrument.

((2)) ** Amount of tax** The amount of the tax imposed by paragraph (1) on any transfer of a residual interest shall be equal to the product of—
((A)) the amount (determined under regulations) equal to the present value of the total anticipated excess inclusions with respect to such interest for periods after such transfer, multiplied by
((B)) the highest rate of tax specified in section 11(b).
((3)) ** Liability** The tax imposed by paragraph (1) on any transfer shall be paid by the transferor; except that, where such transfer is through an agent for a disqualified organization, such tax shall be paid by such agent.
((4)) ** Transferee furnishes affidavit** The person (otherwise liable for any tax imposed by paragraph (1)) shall be relieved of liability for the tax imposed by paragraph (1) with respect to any transfer if—
((A)) the transferee furnishes to such person an affidavit that the transferee is not a disqualified organization, and
((B)) as of the time of the transfer, such person does not have actual knowledge that such affidavit is false.

((B)) ** Pass-thru entity** For purposes of this paragraph, the term “pass-thru entity” means—
((i)) any regulated investment company, real estate investment trust, or common trust fund,
((ii)) any partnership, trust, or estate, and
((iii)) any organization to which part I of subchapter T applies.
((C)) ** Tax to be deductible** Any tax imposed by this paragraph with respect to any excess inclusion of any pass-thru entity for any taxable year shall, for purposes of this title (other than this subsection), be applied against (and operate to reduce) the amount included in gross income with respect to the residual interest involved.
((D)) ** Exception where holder furnishes affidavit** No tax shall be imposed by subparagraph (A) with respect to any interest in a pass-thru entity for any period if—
((i)) the record holder of such interest furnishes to such pass-thru entity an affidavit that such record holder is not a disqualified organization, and
((ii)) during such period, the pass-thru entity does not have actual knowledge that such affidavit is false.
((7)) ** Waiver** The Secretary may waive the tax imposed by paragraph (1) on any transfer if—

((B)) there is paid to the Secretary such amounts as the Secretary may require.
((8)) ** Administrative provisions** For purposes of subtitle F, the taxes imposed by this subsection shall be treated as excise taxes with respect to which the deficiency procedures of such subtitle apply.
