(A) Nonrecognition gain or loss
No gain or loss shall be recognized to the transferor on the transfer of any property to a REMIC in exchange for regular or residual interests in such REMIC.

(B) Adjusted bases of interests
The adjusted bases of the regular and residual interests received in a transfer described in subparagraph (A) shall be equal to the aggregate adjusted bases of the property transferred in such transfer. Such amount shall be allocated among such interests in proportion to their respective fair market values.

(C) Treatment of nonrecognized gain
If the issue price of any regular or residual interest exceeds its adjusted basis as determined under subparagraph (B), for periods during which such interest is held by the transferor (or by any other person whose basis is determined in whole or in part by reference to the basis of such interest in the hand of the transferor)—

(i) in the case of a regular interest, such excess shall be included in gross income (as determined under rules similar to rules of section 1276(b)), and

(ii) in the case of a residual interest, such excess shall be included in gross income ratably over the anticipated period during which the REMIC will be in existence.

(D) Treatment of nonrecognized loss
If the adjusted basis of any regular or residual interest received in a transfer described in subparagraph (A) exceeds its issue price, for periods during which such interest is held by the transferor (or by any other person whose basis is determined in whole or in part by reference to the basis of such interest in the hand of the transferor)—

(i) in the case of a regular interest, such excess shall be allowable as a deduction under rules similar to the rules of section 171, and

(ii) in the case of a residual interest, such excess shall be allowable as a deduction ratably over the anticipated period during which the REMIC will be in existence.

(2) Basis to REMIC
The basis of any property received by a REMIC in a transfer described in paragraph (1)(A) shall be its fair market value immediately after such transfer.

(c) Distributions of property
If a REMIC makes a distribution of property with respect to any regular or residual interest—

(1) notwithstanding any other provision of this subtitle, gain shall be recognized to such REMIC on the distribution in the same manner as if it had sold such property to the distributee at its fair market value, and

(2) the basis of the distributee in such property shall be its fair market value.

(d) Coordination with wash sale rules
For purposes of section 1091—

(1) any residual interest in a REMIC shall be treated as a security, and

(2) in applying such section to any loss claimed to have been sustained on the sale or other disposition of a residual interest in a REMIC—

(A) except as provided in regulations, any residual interest in any REMIC and any interest in a taxable mortgage pool (as defined in section 7701(i)) comparable to a residual interest in a REMIC shall be treated as substantially identical stock or securities, and

(B) subsections (a) and (e) of such section shall be applied by substituting "6 months" for "30 days" each place it appears.

(e) Treatment under subtitle F
For purposes of subtitle F, a REMIC shall be treated as a partnership (and holders of residual interests in such REMIC shall be treated as partners). Any return required by reason of the preceding sentence shall include the amount of the daily accruals determined under section 860E(c). Such return shall be filed by the REMIC.
