Text

(a) Qualified small issue bond
For purposes of this part, the term "qualified small issue bond" means any bond issued as part of an issue the aggregate authorized face amount of which is $1,000,000 or less and 95 percent or more of the net proceeds of which are to be used—
(A) for the acquisition, construction, reconstruction, or improvement of land or property of a character subject to the allowance for depreciation, or
(B) to redeem part or all of a prior issue which was issued for purposes described in subparagraph (A) or this subparagraph.
If—
(A) the proceeds of 2 or more issues of bonds (whether or not the issuer of each such issue is the same) are or will be used primarily with respect to facilities located in the same incorporated municipality or located in the same county (but not in any incorporated municipality),
(B) the principal user of such facilities is or will be the same person or 2 or more related persons, and
(C) but for this paragraph, paragraph (1) (or the corresponding provision of prior law) would apply to each such issue,
then, for purposes of paragraph (1), in determining the aggregate face amount of any later issue there shall be taken into account the aggregate face amount of tax-exempt bonds issued under all prior such issues and outstanding at the time of such later issue (not including as outstanding any bond which is to be redeemed (other than in an advance refunding) from the net proceeds of the later issue).
For purposes of this subsection, a person is a related person to another person if—
(A) the relationship between such persons would result in a disallowance of losses under section 267 or 707(b), or
(B) such persons are members of the same controlled group of corporations (as defined in section 1563(a), except that "more than 50 percent" shall be substituted for "at least 80 percent" each place it appears therein).
At the election of the issuer with respect to any issue, this subsection shall be applied—
(i) by substituting "$10,000,000" for "$1,000,000" in paragraph (1), and
(ii) in determining the aggregate face amount of such issue, by taking into account not only the amount described in paragraph (2), but also the aggregate amount of capital expenditures with respect to facilities described in subparagraph (B) paid or incurred during the 6-year period beginning 3 years before the date of such issue and ending 3 years after such date (and financed otherwise than out of the proceeds of outstanding tax-exempt issues to which paragraph (1) (or the corresponding provision of prior law) applied), as if the aggregate amount of such capital expenditures constituted the face amount of a prior outstanding issue described in paragraph (2).
For purposes of subparagraph (A)(ii), the facilities described in this subparagraph are facilities—
(i) located in the same incorporated municipality or located in the same county (but not in any incorporated municipality), and
(ii) the principal user of which is or will be the same person or 2 or more related persons.
For purposes of clause (i), the determination of whether or not facilities are located in the same governmental unit shall be made as of the date of issue of the issue in question.
For purposes of subparagraph (A)(ii), any capital expenditure—
(i) to replace property destroyed or damaged by fire, storm, or other casualty, to the extent of the fair market value of the property replaced,
(ii) required by a change made after the date of issue of the issue in question in a Federal or State law or local ordinance of general application or required by a change made after such date in rules and regulations of general application issued under such a law or ordinance,
(iii) required by circumstances which could not be reasonably foreseen on such date of issue or arising out of a mistake of law or fact (but the aggregate amount of expenditures not taken into account under this clause with respect to any issue shall not exceed $1,000,000), or
(iv) described in clause (i) or (ii) of section 41(b)(2)(A) for which a deduction was allowed under section 174A(a),
shall not be taken into account.
In applying subparagraph (A)(ii) with respect to capital expenditures made after the date of any issue, no bond issued as a part of such issue shall cease to be treated as a qualified small issue bond by reason of any such expenditure for any period before the date on which such expenditure is paid or incurred.
In the case of any issue described in paragraph (1)(B), an election may be made under subparagraph (A) of this paragraph only if all of the prior issues being redeemed are issues to which paragraph (1) (or the corresponding provision of prior law) applied. In applying subparagraph (A)(ii) with respect to such a refinancing issue, capital expenditures shall be taken into account only for purposes of determining whether the prior issues being redeemed qualified (and would have continued to qualify) under paragraph (1) (or the corresponding provision of prior law).
In the case of any issue 95 percent or more of the net proceeds of which are to be used to provide facilities with respect to which an urban development action grant has been made under section 119 of the Housing and Community Development Act of 1974, capital expenditures of not to exceed $10,000,000 shall not be taken into account for purposes of applying subparagraph (A)(ii). This subparagraph shall not apply to bonds issued after December 31, 2006.
With respect to bonds issued after December 31, 2006, in addition to any capital expenditure described in subparagraph (C), capital expenditures of not to exceed $10,000,000 shall not be taken into account for purposes of applying subparagraph (A)(ii).
This subsection shall not apply to any bond issued as part of an issue 5 percent or more of the net proceeds of which are to be used directly or indirectly to provide residential real property for family units.
For purposes of this subsection, separate lots of bonds which (but for this subparagraph) would be treated as part of the same issue shall be treated as separate issues unless the proceeds of such lots are to be used with respect to 2 or more facilities—
(i) which are located in more than 1 State, or
(ii) which have, or will have, as the same principal user the same person or related persons.
For purposes of subparagraph (A), a person (other than a governmental unit) shall be considered a principal user of a facility if such person (or a group of related persons which includes such person)—
(i) guarantees, arranges, participates in, or assists with the issuance (or pays any portion of the cost of issuance) of any bond the proceeds of which are to be used to finance or refinance such facility, and
(ii) provides any property, or any franchise, trademark, or trade name (within the meaning of section 1253), which is to be used in connection with such facility.
This subsection shall not apply to any bond issued as part of an issue (other than an issue to which paragraph (4) applies) if the interest on any other bond which is part of such issue is excluded from gross income under any provision of law other than this subsection.
This subsection shall not apply to an issue if—
(A) more than 25 percent of the net proceeds of the issue are to be used to provide a facility the primary purpose of which is one of the following: retail food and beverage services, automobile sales or service, or the provision of recreation or entertainment; or
(B) any portion of the proceeds of the issue is to be used to provide the following: any private or commercial golf course, country club, massage parlor, tennis club, skating facility (including roller skating, skateboard, and ice skating), racquet sports facility (including any handball or racquetball court), hot tub facility, suntan facility, or racetrack.
For purposes of this subsection, 2 or more issues part or all of the net proceeds of which are to be used with respect to a single building, an enclosed shopping mall, or a strip of offices, stores, or warehouses using substantial common facilities shall be treated as 1 issue (and any person who is a principal user with respect to any of such issues shall be treated as a principal user with respect to the aggregated issue).
This subsection shall not apply to any issue if the aggregate authorized face amount of such issue allocated to any test-period beneficiary (when increased by the outstanding tax-exempt facility-related bonds of such beneficiary) exceeds $40,000,000.
For purposes of applying subparagraph (A) with respect to any issue, the outstanding tax-exempt facility-related bonds of any person who is a test-period beneficiary with respect to such issue is the aggregate amount of tax-exempt bonds referred to in clause (ii)—
(I) which are allocated to such beneficiary, and
(II) which are outstanding at the time of such later issue (not including as outstanding any bond which is to be redeemed (other than in an advance refunding) from the net proceeds of the later issue).
For purposes of clause (i), the bonds referred to in this clause are—
(I) exempt facility bonds, qualified small issue bonds, and qualified redevelopment bonds, and
(II) industrial development bonds (as defined in section 103(b)(2), as in effect on the day before the date of the enactment of the Tax Reform Act of 1986) to which section 141(a) does not apply.
Except as otherwise provided in regulations, the portion of the face amount of an issue allocated to any test-period beneficiary of a facility financed by the proceeds of such issue (other than an owner of such facility) is an amount which bears the same relationship to the entire face amount of such issue as the portion of such facility used by such beneficiary bears to the entire facility.
Except as otherwise provided in regulations, the portion of the face amount of an issue allocated to any test-period beneficiary who is an owner of a facility financed by the proceeds of such issue is an amount which bears the same relationship to the entire face amount of such issue as the portion of such facility owned by such beneficiary bears to the entire facility.
For purposes of this paragraph, except as provided in regulations, the term "test-period beneficiary" means any person who is an owner or a principal user of facilities being financed by the issue at any time during the 3-year period beginning on the later of—
(i) the date such facilities were placed in service, or
(ii) the date of issue.

In determining the amount of proceeds of an issue to be used as described in subparagraph (A), there shall be taken into account the aggregate amount of each prior issue to which paragraph (1) (or the corresponding provisions of prior law) applied which were or will be so used.
This subsection shall not apply to—

In the case of any issue made after the date of enactment of this clause and before January 1, 2011, clause (ii) shall not apply and the net proceeds from a bond shall be considered to be used to provide a manufacturing facility if such proceeds are used to provide—
(I) a facility which is used in the creation or production of intangible property which is described in section 197(d)(1)(C)(iii), or

An area may be designated by a governmental unit as a blighted area only if the designation percentage with respect to such area, when added to the designation percentages of all other designated blighted areas within the jurisdiction of such governmental unit, does not exceed 20 percent.
For purposes of this subparagraph, the term "designation percentage" means, with respect to any area, the percentage (determined at the time such area is designated) which the assessed value of real property located in such area is of the total assessed value of all real property located within the jurisdiction of the governmental unit which designated such area.
