Definitions and special rules
The term “bond” includes any obligation.
The term “governmental unit” does not include the United States or any agency or instrumentality thereof.
The term “net proceeds” means, with respect to any issue, the proceeds of such issue reduced by amounts in a reasonably required reserve or replacement fund.
The term “501(c)(3) organization” means any organization described in section 501(c)(3) and exempt from tax under section 501(a).
Property shall be treated as owned by a governmental unit if it is owned on behalf of such unit.
The term “tax-exempt” means, with respect to any bond (or issue), that the interest on such bond (or on the bonds issued as part of such issue) is excluded from gross income.
In the case of any residence with respect to which financing is provided from the proceeds of a tax-exempt qualified mortgage bond or qualified veterans’ mortgage bond, if there is a continuous period of at least 1 year during which such residence is not the principal residence of at least 1 of the mortgagors who received such financing, then no deduction shall be allowed under this chapter for interest on such financing which accrues on or after the date such period began and before the date such residence is again the principal residence of at least 1 of the mortgagors who received such financing.
Subparagraph (A) shall not apply to the extent the Secretary determines that its application would result in undue hardship and that the failure to meet the requirements of subparagraph (A) resulted from circumstances beyond the mortgagor’s control.
No deduction shall be allowed under this chapter for interest on financing described in subparagraph (A) which accrues during the period beginning on the date such facility is used as described in subparagraph (A)(i) and ending on the date such facility is not so used.
In the case of any facility with respect to which financing is provided from the proceeds of any private activity bond to which this paragraph applies, if such facility is not used for a purpose for which a tax-exempt bond could be issued on the date of such issue, no deduction shall be allowed under this chapter for interest on such financing which accrues during the period beginning on the date such facility is not so used and ending on the date such facility is so used.
This paragraph applies to any private activity bond which, when issued, purported to be a tax-exempt exempt facility bond described in a paragraph (other than paragraph (7)) of section 142(a) or a qualified small issue bond.
In the case of any financing provided from the proceeds of any bond which, when issued, purported to be a qualified small issue bond, no deduction shall be allowed under this chapter for interest on such financing which accrues during the period such bond is not a qualified small issue bond.
Any use with respect to facilities financed with proceeds of an issue which are not required to be used for the exempt purpose of such issue shall not be taken into account.
If the amounts payable for the use of a facility are not interest, subsection (b) shall apply to such amounts as if they were interest but only to the extent such amounts for any period do not exceed the amount of interest accrued on the bond financing for such period.
In the case of any person which uses only a portion of the facility, only the interest accruing on the financing allocable to such portion shall be taken into account by such person.
In the case of any facility where part but not all of the facility is not used for an exempt purpose, only the interest accruing on the financing allocable to such part shall be taken into account.
The Secretary shall prescribe such regulations as may be necessary or appropriate to carry out the purposes of this subsection and subsection (b).
A qualified scholarship funding bond shall be treated as a State or local bond.
Any qualified scholarship funding bond, and qualified student loan bond, outstanding on the date of the issuer’s election under this paragraph (and any bond (or series of bonds) issued to refund such a bond) shall not fail to be a tax-exempt bond solely because the issuer ceases to be described in subparagraphs (A) and (B) of paragraph (2) if the issuer meets the requirements of subparagraphs (B) and (C) of this paragraph.
An election under this paragraph may be revoked only with the consent of the Secretary.
Bonds which are part of an issue which meets the requirements of paragraph (1) shall not be treated as private activity bonds except for purposes of sections 147(f) and 149(d).
